Inexpensive and technologically advanced heating option- plastic pipes.

They are durable, easy to install and inexpensive. A well-welded polypropylene system can serve 30-60 years without repair, but there are factors that significantly reduce service life and reliability.

This excessive temperature, pressure, prolonged exposure to direct sunlight. Polypropylene pipes should not be used when connecting a solid fuel boiler, on steam lines, in contact with hot metal, or in heating systems of multi-apartment high-rise buildings.

Types of polypropylene pipes

The manufacturer makes markings throughout the product. It indicates the type of material, nominal pressure, operating temperature, diameter, wall thickness, ultraviolet protection .

Depending on the wall material, pipes are distinguished:

• Monolithic. They are used to transport liquids at low pressure and temperature. Used for water supply and irrigation systems. Denoted as PPH, PPB. Nominal pressure PN15, PN 20.
• Random copolymer. They are used in water supply systems and in the organization of low-temperature heating - warm floors. Designated PPR. Nominal pressure PN20 - PN 25.
• Heat-resistant reinforced - PPS. The strength of such pipes is higher than metal-plastic, and they are used in heating systems. Nominal pressure PN 25. Withstands temperature 95 °C, used in any heating systems of private houses.
• Reinforced. The walls of polypropylene pipes can be made either from monolithic polypropylene or reinforced with fiberglass or aluminum foil. Reinforcement is needed to increase strength, durability and reduce linear expansion.

Important! In heating systems, the most versatile and widely used are composites - glass fiber reinforced products.

How to solder a heating system

The huge advantage of polypropylene pipes is ease and manufacturability of docking. The connection is uniform and monolithic. Each type of pipe is connected according to own technology

End connection

Applicable for large diameter main pipes. They are soldered using heated air and a filler rod. The process is similar to welding metal with an electrode.

An irresponsible joint can also be obtained with small diameters by heating the ends up to 270 °C and joining the pipes. This method is not used, since the joint is weak, porous, and leaks are possible.

Electrofusion connection

Applicable for high-quality connections of high-pressure pipelines. The ends of the connections are cleaned and compressed with casing clamps. A coupling with electric heaters already sealed in it is installed at the joint. The clamps are loosened, a fixing and centering clamp is put on. A direct electric current is connected to the coupling contacts. Voltage, current and heating time are indicated on the coupling. After heating, the joint cools down, after which it is ready for use.

Socket soldering

Used for small diameters - up to 62 mm. To connect, you will need factory-made shaped elements: adapters, tees, couplings, taps, fittings, turns.

For soldering you will need: soldering iron with Teflon tips, pipe cutters, clean rags, degreaser, ruler and pencil.

We cut the connected pipes to the required size using spring scissors. When measuring it is left margin 8-10 mm for the joint.

Photo 1. The process of socket soldering of polypropylene pipes. A special soldering iron is used for this.

Degrease and clean the ends and seats in the fitting. Dirt, grease and water interfere with the welding of polypropylene; a sealed, reliable joint will not work.

Mark the depth at the end of the pipe seat in the fitting. A few millimeters reserve for excess plastic.

If a pipe reinforced with aluminum foil is welded, we use a special “sharpener”, it will evenly cut the reinforcement, and the joint will be reliable.

Attention! Surface of welded polypropylene must be clean and dry. We use rags and degreaser. Be sure to remove water in case of repairs or alterations to the system.

Heat the soldering iron to temperature 260-280 °C. We attach the pipe and coupling with non-Teflon tips, hold 5-7 seconds. After heating, connect the joint and fix it for 10-15 seconds.

Polypropylene is welded into a monolith during heating. Therefore, it is not worth adjusting the position, tightening or pressing - the joint will turn out to be of poor quality.

If the inside of the fitting overheats, plastic residue may narrow or even block the fitting.

Space is left in the mounting socket for excess plastic 2-3 mm.

Therefore, the marking stage is also important.

The cooled joint can be used immediately.

The connection gains strength as it cools.

Polypropylene for heating

Polypropylene pipes are used to transport coolant liquid from the boiler to the battery heat exchangers. When designing a heating system, you should pay attention to:

• Diameter. The larger the cross-section, the lower the hydrodynamic resistance and the further the coolant can be supplied.
• Material. For a “warm floor”, it is enough to use cross-linked polyethylene; for the installation of radiator heating, a fiberglass-reinforced pipe for hot water is used; for piping the boiler, it is better to use a heat-resistant PPS pipe. The piping of a solid fuel boiler is made of metal.
• Length of straight pipeline sections. Polypropylene has a disadvantage - linear expansion. When heated, the length of the pipe changes. Therefore, you should not rigidly fix corner connections, but design compensation loops and bends on long straight sections.

Polypropylene is used in any heating system.

It is suitable for both battery systems and heated floors.

Polypropylene is not suitable for use in systems with overheated coolant ( above 95 °C) or high pressure (above 10 atmospheres).

How to make a heating system in a private house with your own hands

There are a large number of heating systems. Each system has its own characteristics and is used to solve specific problems. When choosing, you should pay attention to the following initial data:

• Number of storeys and area of ​​the house. For heating several floors they are used complex systems with calculation of hydrodynamic resistance. A distribution system with a riser, a “Tichelman loop,” is suitable. For a one-story building with a simple layout, the Leningradka single-pipe system will be optimal, simple system lower spill.
• Layout and aesthetic considerations. To prevent pipes from spoiling the appearance of the walls or interfering with the installation of furniture, you can design decorative screens for the upper spill, or hide the lower spill in the walls or floor screed. Pipes should not pass under doors and should not interfere with walking. Heat is evenly distributed throughout the heated room.
• Energy dependence. If your home experiences frequent and prolonged power outages, it is better to design a gravity system with an open expansion tank. If there are no power outages, use a more efficient closed system with membrane expansion tank and forced circulation. Pipes may be of smaller diameter.
• Power. Depends on the heat loss of the house. The greater the power of the system, the larger the diameter of the pipes to facilitate coolant circulation.

Installation tools

To assemble the system you will need an inexpensive and accessible set of accessories.

• Tools for working with polypropylene. This is a soldering iron, pipe cutter, rags, ruler, pencil, degreaser. To remove aluminum reinforcement, you will need a reamer of the appropriate diameter.

Photo 2. Special soldering iron for connecting polypropylene pipes. The device has two holes of different diameters.

• Set of plumbing accessories- open-end and adjustable wrenches, fum tape, pliers.
• Kit construction tools: hammer drill, grinder, foam gun, mixer.

Stages of work, heating design diagram

The heating system is assembled in successive logical steps.

• Marking the installation of the boiler and batteries. Radiators are placed at the entrance and under windows to create proper convection currents in the room. The boiler can be installed in a boiler room; some types can be placed near any external wall.
• Determination of pipe locations. We definitely design compensation loops - the length of polypropylene pipes changes when heated.
• Hanging the boiler and its piping. If necessary, we connect water and gas to it. It is better to make the piping of a solid fuel boiler from metal. The gas boiler is connected with polypropylene pipes with heat-resistant characteristics.
• With a collector system, we connect the “comb” - distributor. If the system is two-three-arm, you can get by with tees.
• We install the expansion tank and safety group. The volume of the expansion tank is calculated based on the volume of water in the system.
• We fix fasteners to the floor or wall. If the system is with gravitational circulation, we observe the slopes.
• We install pipes and connect batteries.
• After installation is completed, we pressurize the system. We disconnect the batteries and plug all the outputs. We supply air under pressure 8-10 atmospheres. If fistulas are identified, we eliminate them.
• We connect the batteries, boiler, expansion tank.
• Fill in water system, remove air from the highest points.
• We are conducting a trial run. We pay attention to pipes, joints, and connection points. We check the uniformity of heating of the batteries.
• We seal the pipes into a screed, wall or decorative box.

You can design and install heating system elements made from polypropylene-based pipes on your own. Such heating will be of particular interest to owners of private houses and various types of country houses who carry out home improvement work on their own.

Before proceeding with the installation of polypropylene heating, it is necessary to consider the main advantages of such a solution, select a heat source, understand pipe routing diagrams, master the basic nuances of installing elements, and then carry out the wiring in accordance with the chosen scheme.

DIY polypropylene heating

Advantages of polypropylene pipes

Before you begin installing polypropylene heating on your own, you need to select a suitable heating source.

Gas

A gas boiler

If there is a gas pipeline near the house, you need to buy the appropriate equipment. The best option for arranging a heating system made of polypropylene is a modern wall-mounted boiler model with protective mechanisms, the necessary pumps and automatic monitoring and control equipment.

If desired, you can abandon the traditional chimney by choosing a boiler model with a closed combustion chamber and a special coaxial tube through which oxygen will be supplied to the unit and exhaust air will be removed from it.

The air exchange pipe can be led outside through the wall of the building, which is a much more financially beneficial undertaking when compared with installing a standard type chimney.

Electricity

Electric boiler Proterm

If electricity will be used to heat the house, then it is best to buy an automated heating boiler equipped with a pump, the necessary safety equipment, and an expansion tank.

The easiest way to install such a heating system is to do it yourself.

Solid fuel

Solid fuel boiler

If you plan to use various types of solid fuel for heating, you need to competently approach the development of a piping scheme heating boiler to avoid many mistakes. On leaving heating unit the coolant temperature reaches about 1000 degrees, which imposes a number of additional requirements for the installation of the heating system.

There are also options for arranging heating systems using other energy sources, however, in the case of installing polypropylene pipes, it is better to refrain from using them.

Heating system diagrams

Select optimal scheme pipe routing for self-installation heating made of polypropylene. In the future, you will receive recommendations for connecting individual elements and place them in accordance with the chosen plan.

Single-pipe scheme

Single-pipe scheme

The simplest method of arranging a heating system. In accordance with this wiring method, each battery installed further from the heating unit will heat up to a lower temperature compared to the previously installed battery.

This method makes it possible to reduce the consumption of materials for the arrangement of the heating system. However, the heating efficiency will be low, because The temperature distribution with such pipe routing is uneven.

In view of this, you should try to refrain from a single-pipe pipe routing scheme.

Collector circuit

Collector circuit

To equip a heating system according to this scheme, you will have to spend more materials, however, the basic operational properties of such heating will be much higher.

Heat distribution throughout the rooms will be fairly uniform and high quality.

Two-pipe system

Two-pipe system

The most optimal method of arranging a heating system. The pipes are laid into the floor or into the walls of the house around the perimeter. Two-pipe heating is best suited for heating a home. Therefore, experts recommend giving preference to this particular pipe routing option.

What pipes should I use?

During the installation of a heating system from the pipes in question, you may need to connect plastic elements with metal-plastic pipes. When performing such work, make sure that the diameters of both types of pipes match each other.

Connections of polypropylene and metal pipes to each other

Follow the following pattern:

• for connection to metal-plastic products 20x2 mm, use polypropylene pipes measuring 25x4.2 mm;
• to metal-plastic pipes with dimensions of 16x2 mm, you need to connect polypropylene pipes with dimensions of 20x3.4 mm;
• To metal pipes with dimensions 26x3 mm, polypropylene pipes having dimensions 32x5.4 mm are connected.

If pipes are laid to the batteries in the house from the main pipeline, and the wiring is carried out in accordance with a two-pipe scheme, it is necessary to lay a polypropylene pipe measuring 20x3.4 mm.

Polypropylene pipes

The use of pipes with a larger diameter does not make much sense. There is also no point in using radiator valves larger than 1.2 inches. Therefore, the statement that as the diameter of polypropylene pipes and thermostatic valves increases, the rooms become warmer is not true.

To ensure the required performance of the heating system, it is important that the supply pipeline between the boiler and the latest battery is no more than 25 m long. In this case, the boiler power should not exceed 12 kW.

Thus, in order for, for example, a heating system with pipes measuring 20x3.4 to work as efficiently and correctly as possible, it must include a maximum of 6 batteries of 10 sections each.

If it is necessary to connect more batteries, the length of the pipes for their installation will have to be increased, which will negatively affect the uniform heating of batteries installed at a greater distance from the heating boiler.

Installation of heating from polypropylene pipes and aluminum radiators

However, if you cannot refuse to connect more batteries or increase the length of pipes, equip the heating system using pipes of a larger cross-section. For example, 32x5.4 mm. Connect metal-plastic pipes 26x3 mm to them.

There is also another option for solving this problem - instead of one heating circuit, you can equip two.

Important features of work

Before you begin heating installation work, familiarize yourself with the basic recommendations for connecting system elements.

To connect pipes, as already noted, a special soldering iron is used. It is most convenient to do this work together with a partner.

Soldering iron for soldering polypropylene pipes

The instructions for soldering polypropylene pipes yourself are extremely simple. It is only important to prevent overheating of the ends of the mating elements and to have time to firmly fix the fittings and polypropylene pipes within ten seconds after they are connected.

It was previously noted that polypropylene pipes normally tolerate defrosting of the heating system. However, it is important to remember that in addition to pipes, the system also includes expansion tanks and, of course, a boiler, and they can break when the system defrosts.

Heating installation guide

Soldering technology for polypropylene pipes

Pre-prepare a diagram of the system wiring, installation of batteries, and connection of the boiler. In the future, you will perform all necessary work in accordance with this scheme.

The actual work of installing pipes is carried out in several simple steps.

Welding time table for polypropylene pipes

Soldering machine plastic pipes

First step

Calculate the layout of polypropylene pipes.

Second step

Calculate the length of the polypropylene pipe sections in each section of the heating system. Install suitable look fitting.

Marking

Third step

Determine the required welding time for the joints. It depends on the diameter of the pipes used and is specified in the relevant reference literature. First bring all the elements of the heating system into the room and let them warm up to room temperature.

Fourth step

In accordance with the calculated data, mark the places where the pipes will be cut using a marker.

Fifth step

Make a cut using special scissors. Cut perpendicular to the surface.

PP pipe cutting

Sixth step

Wipe the sections with an alcohol solution and remove any dirt present with a dry cloth.

Preparing the fitting

Seventh step

Take a soldering nozzle that matches the cross-sectional diameter of the pipes, degrease it, and then set it horizontally and let it heat up to 265 degrees.

Installation of PP pipes

Place the pipe and fitting into the heater holes, select the required heating time from the table and directly heat the elements being connected. After this, carefully remove the products, insert the pipe into the fitting and hold for the required time. It is better not to touch the elements being connected until they have cooled completely.

Pipe welding

Using a similar scheme, solder all the pipes of the heating system, focusing on the drawings you have. Connect pipes to the heating device and radiators also according to the drawings.

To prevent pipes from sagging in the future, ensure that they are frequently attached to the surface using clips. For polypropylene system optimal temperature The coolant is 60 degrees.

Good luck!

Heating schemes in a private house made of polypropylene

The organization of a heating system in a private home involves the possibility of laying communications using polypropylene pipes. Thanks to the operational and technical specifications products used, a heating scheme in a private house made of polypropylene pipes can be drawn up by an ordinary person, without much experience in the construction industry. As a rule, the help of specialists is necessary only for completely inexperienced and completely unconfident homeowners. However, those who nevertheless decide to carry out the necessary work without outside assistance will first need heating schemes in a private house made of polypropylene pipes, as well as a small amount of theoretical knowledge and the desire to create comfort and coziness in their own home.

Construction industry specialists assure that there are practically no difficulties in the process of designing a heating system based on a private building. This makes it possible for anyone who wants to carry out all the calculations with their own hands, develop a project with drawings, illustrations and other materials that will fully reflect the design of the future system.

Graphic diagram of a house heating system

Main material – pipes

In the process of designing a heating system at home, you will have to face the need to clearly define the technical characteristics of the pipes that you will use in the future. Meanwhile, it is necessary to take into account that the average person who is not a professional employee of the construction industry and does not have full knowledge about the entire variety of products with different operational and technological characteristics will simply not be able to quickly study the proposed range of products in the corresponding market segment. The parameters that characterize products in this category are as follows:

• logo illustrating the manufacturer's trademark;
• abbreviation for functional purpose products, as well as data on a specific modification;
• conditional pressure indicator, which is acceptable for the working environment;
• indication of the wall thickness of the product and its diameter along the external border;
• operational class;
• product standard;
• the maximum permissible pressure value, measured in bar.

Single pipe heating system with top wiring

Combinations of these parameters directly determine the operational period of a particular product.

Product categories

It is worth noting that not only the diameter and service life determine the applicability of a particular product in the heating system of a private home. There is one more criterion that will have to be taken into account in the process of creating a heating installation scheme made from polypropylene pipes. Modern manufacturers offer us products reinforced with aluminum or fiberglass. Actually, pipes improved with the help of a material such as aluminum are relevant in terms of applicability in heating systems. Meanwhile, fiber-enhanced products are widely used. They are the optimal solution for underfloor heating systems, radiator-type circuits and hot water supply to private buildings. However, it is worth considering that those products that are covered with fiberglass on the inside require a slight elongation of sections of the linear format under conditions of rising temperatures and some permeability of oxygen.

Bottom heating system wiring

Heating system components

Of course, it is quite obvious that there is a certain number of elements in the system:

• expansion tank;
• boiler;
• radiator, one or more;
• wiring

Provided that the dimensions of a private house are large enough, it becomes possible to allocate a separate room for the boiler - a boiler room. However, in such a situation it is extremely necessary to provide combustion products with the opportunity to naturally exit the system. This refers to the installation of a chimney. If you decide to equip a small boiler room in your own home, cover the walls of the room special composition, thanks to which the fire will not be able to spread throughout the building in the event of a boiler fire. This is a traditional requirement for the safety level of the heating system in any private home.

What do you need to consider?

Before proceeding with direct calculations and subsequent development of drawings and diagrams, it is important to determine the length of polypropylene pipes. In this matter, you will have to take into account a number of factors, the main ones being:

• parameters of premises in the building;
• location, angle and number of pipe turns within the system;
• number of pipe connection points;
• actual number of piers;
• such a floor parameter as length.

Remember that ready-made heating schemes for a private house made of polypropylene are presented on the Internet in a wide variety, and therefore you can check the accuracy of your own drawings using samples published on various resources.

Single pipe heating system

Execution options

In the construction industry there are two traditional options organization of systems of the described type. Their separation is based on the type of supply carried out by the coolant. So, there are categories of upper and lower execution. If we talk about correct execution, then the liquid circulates within the functioning system naturally, that is, independently. In the second option, in order to force the liquid to move through the pipes, it is assumed that a pressure-type pump is used. The second option is perfect for multi-story buildings, because without a pressure pump it is impossible to make the liquid circulate at more than one level.

Specifics of installation work

When developing a diagram of a communication system made of polypropylene pipes with your own hands, you need to understand that there are certain nuances of installation work. First of all, you should carefully study the capabilities and applicability of elements such as wiring, as well as a radiator. Experts with many years of experience in the construction industry strongly recommend giving preference to hydraulic modification of heating, which involves two-pipe forced circulation of liquid, as well as the use of radiators made of aluminum. Aluminum batteries They have excellent properties, due to which they heat up very quickly, while cooling down for quite a long time.

Tools

Since working on organizing heating from polypropylene pipes with your own hands involves carrying out a number of construction operations, it is necessary to collect an appropriate set of tools and devices. These traditionally include:

• electric jigsaw;
• marker;
• fitting;
• perforator;
• roulette;
• trimmer

If you provide yourself with this set of tools and devices in advance, the process of implementing a heating communication project will be significantly simplified and will take a minimum amount of time.

Two-pipe heating system

Of course, tools alone are not enough in construction. In many ways, the success and quality of the result depend on the experience of the employee. If you cannot boast of having a sufficient number of practical skills, you should turn to the recommendations of professionals that are offered, for example, on the Internet. So, experienced experts suggest paying attention to the following points:

• You can start directly cutting pipes only after the installation of all large equipment, for example, batteries, boilers, dispensers or expansion tanks, has been completed;
• in order to divide the existing pipes into a certain number of blanks, it is best to use special construction scissors, strictly observing an angle of ninety degrees;
• when the holding elements are installed, the sagging is eliminated, and a sufficient level of installation reliability is ensured;
• any work related to the use of polypropylene products requires a certain temperature regime in the room;
• with the help of fum tape it is easiest to achieve reliability and high quality connections of fitting elements;
• when polypropylene pipes are cut, sloppy cut edges remain on the product, which can be easily removed using a trimmer;
• in order for the connection to be fixed in the best possible way, it is enough to use a welding device;
• after connection using welding machine it is necessary to give the material some time to completely cool and, accordingly, harden.

Example horizontal wiring

To make your home safe and, at the same time, warm and comfortable, you need to analyze absolutely everything. You will have to thoroughly study the methods of laying pipeline systems, the number of floors of an architectural object, the load exerted on each specific battery, and much more. You should not completely refuse the help of qualified specialists, because the information that you can study on your own may simply not be enough if you plan to build heating in unusual conditions. Remember that the main thing is to achieve a result, which in this case involves creating the most efficient object that can easily cope with heavy loads and will last for many years.

Heating from polypropylene pipes in a private house

Today's rating modern technologies impresses its consumers (SNiP). Thanks to them, you can install and solder heating systems of various variations. Installation of heating from polypropylene pipes can be carried out either with the help of specialists or with your own hands.

Do-it-yourself heating connection in a private house using a manifold and polypropylene pipes is one of the best options. The welding scheme for this method does not require complex equipment. Professionals especially recommend using a manifold and polypropylene pipeline, as they increase the service life (SNiP).

High temperatures damage the aluminum pipe; it becomes covered with rust from the inside, but if you use a polypropylene pipeline (fiberglass), its technical characteristics will protect you from such welding problems.

Marking polypropylene pipes according to GOST for heating, if you do it yourself, has its advantages, but also disadvantages of welding.

1. Simple connection - this battery installation scheme is easy to do with your own hands, and everything can be done with little time using a collector.
2. Large operational flow – more than 50 years. Reliability - since the pipeline has high quality, water supply problems will not bother you, just like the riser. Leakage is excluded;
3. Low price for materials, connection, riser, manifold. Installing batteries with polypropylene pipes in a private house will cost much less;
4. The technology is harmless to nature;
5. The efficiency of GOST pipes is excellent thermal insulation characteristics: acceptable temperature, the riser is not affected;
6. Sound insulation. This quality ensures silent operation;
7. You can install heating from polypropylene pipes with your own hands in a private house inside a building structure;
8. The decision to choose one material or another depends on the collector, in what condition the riser will be, as well as the quality of the work done, in general. If you want to solder the heating system and manifold, it is best to choose reinforced fiberglass for the pipeline;
9. Temperature affects the riser and the performance of the unit. Be sure to make sure that the temperature is not too high, otherwise the pipeline is GOST and the insulation may fail.

How to choose polypropylene pipes for heating

Which diameter to choose

There is a large selection of polypropylene pipes, so you need to know their diameter and properties for an error-free PN-10 connection.

1. Outside diameter is 20, 25, 32, 40-110 mm.
2. Inner diameter – 16.2, 25, 32, 40 – 90 mm.

A rare species that makes it possible to use pipes at temperatures of 80 °C. PN-20.

1. Inner diameter – 10.6, 25, 32, 40 -73.2 mm.
2. External diameter – 16, 25, 32, 40 -110 mm.

Can be used with wall thicknesses from 16 mm. up to 18.4 mm. for welding. The pipes are universal - temperatures during their use are allowed up to 80 °C. The pressure cannot exceed 2 MPa. PN-25.

It is best used for installing and welding batteries in a private home with your own hands. The peculiarity is two layers of plastic, between which an aluminum gasket coated with glue is laid. The aluminum unit has an internal diameter with dimensions ranging from 13.5, 25, 32, 40 -50 mm, external diameter 21.2, 25, 32-77.9. They operate at 90 °C and pressure up to 2.5 MPa.

Hot water supply does not harm the pipes, thanks to the aluminum layer. In the event that you had to choose reinforced products for welding, it will be necessary to take into account its location, as well as take into account how its taps are located. Soldering and insulation will be difficult if placed on the outside.

Can be done reinforced pipelines using fiberglass. The quality is similar to foil welding technology. The first option is reinforced (fiberglass), their technical characteristics guarantee high thermal expansion, however, installation is quite simple. The technology for connecting a pipeline (diameter not exceeding 25, 32.63 mm) has two methods:

1. Socket soldering.
2. Socket welding.

A plus option is a threaded connection. To implement this, you will need fittings equipped with a socket. The pipeline can also be connected if butt soldering occurs - no couplings are required. Fittings – if they are selected correctly, you can also use couplings.

Correct step-by-step installation (SNiP).

For correct installation batteries, there is a diagram - follow it. (1) Ext. Pipe diameter (2) Heating (sec) (3) Connection (sec) (4) Cooling (min). (mm)

(1) 75 (2) 30 (3) 10 (4) 8 (1) 16 (2) 5 (3) 4 (4) 2 (1) 20 (2) 7 (3) 4 (4) 2 (1) 25 (2) 7 (3) 4 (4) 2 (1) 32 (2) 8 (3) 6 (4) 4 (1) 40 (2) 12 (3) 6 (4) 4 (1) 50 (2) 18 (3) 6 (4) 4

(1) 63 (2) 24 (3) 8 (4) 6

Step 1. The layout of polypropylene pipes according to GOST must be calculated; Step 2. Next is the length. It is necessary to accurately calculate the size of the pipes in each heating location and install the necessary fittings; Step 3. One or another welding time for the connection is determined - it depends on the diameter of the pipes used. Next, we bring all the elements into the room: their temperature should be room temperature; Step 4. Mark (using a marker) the places where the pipes will be cut; Step 5. Use scissors to cut PP pipes. Pipes are cut perpendicularly; Step 6. Fittings are prepared: the elements are cleaned of all dirt with a dry cloth; Step 7

After preparation, we move on to the process. Based on the cross-section of the pipes, take a fat-free nozzle for the welding machine. Installs and heats horizontally up to 265°C.

The fittings and pipe fit into the heater opening and are heated accordingly to the desired connection. After removal, the elements are connected.

Wait until they cool completely

Water heating scheme (SNiP)

You can choose your own polypropylene water supply schemes for a private house based on the stages of economy and comfort - non-volatile, pressure, one- or two-pipe scheme. Series connection chain of a radiator - a system with conventional circulation, for heating in a small private house

Wiring examples

1. Single-pipe wiring Serial pipeline (fiberglass) - water passes through the batteries in series. The last pipeline (battery) receives water at a temperature much lower than the initial one. When it breaks down, the radiator becomes a problem - fixing it requires shutting down the entire system and disconnecting the entire radiator. Therefore, repairs are considered difficult.
2. Two-pipe wiring This system is suitable for almost any building and home. It differs from single-pipe wiring in that the heat is distributed evenly - the temperature does not decrease. From the radiator, water is directed into the riser, and then into the pipeline, evenly distributing heat. From one radiator, water flows into another, thus passing through each one.

Also, with this wiring it is possible to turn off each radiator individually. The system is equipped with two tubes that have their own taps:

1. Outlet tube;
2. Supply tube.

Two-pipe wiring is divided into a pipeline with upper and lower wiring. Each of them uses its taps, riser, fiberglass differently, and the flow of water from the radiator to other welding elements depends on the type of wiring.

It is better to choose a connection in your home, having studied all the characteristics of the water supply, see what the maximum insulation is with aluminum foil, etc. Check the taps, riser, manifold, fiberglass, condition of the radiator; insulation of the material is also very important. In order to competently and accurately produce a unit with your own hands, you need to study all the elements of welding, be able or learn to solder parts (reinforced, with aluminum foil), know the exact diameter, since it is very important: 32, 25, 40 mm, etc. Knowing the diameter of the part, you can safely start soldering all the elements, be it wiring taps, reinforced pipes or wall sections.

Do-it-yourself heating from polypropylene pipes in a private house

aqueo.ru » Heating » Do-it-yourself heating from polypropylene pipes in a private house

The topic of reliability, efficiency and durability of the heating system of private houses in our country will always be relevant due to climatic conditions. Therefore, homeowners have to think about how to achieve this with minimal costs financial resources and time.

Heating system made of polypropylene pipes in a private house

To do this, at a minimum, the following conditions must be met:

• competently draw up a project for the location of the main elements of the heating system in the house;
• choose quality equipment, tools and pipes;
• plan the sequence of installation work;
• If possible, do all or most of the installation yourself.

Rich long-term operating experience steel pipes and cast iron radiators indicates the difficulties in these heating systems during installation and operation. The main disadvantages include the large weight of all elements, which complicates installation work and contributes to the clogging of pipes with scale and rust products. Gradually people are moving away from these ancient technologies.

It is very practical to use a heating system with copper pipes; it does not rust, therefore it is durable, but very expensive. More and more people are inclined to use polypropylene pipes. Let's consider this option.

Advantages

• In heating systems, one of the advantages of polypropylene pipes is high thermal insulation. This ensures low heat loss on the way to the radiator, less fuel is consumed for heating, and higher efficiency.
• In terms of service life, polypropylene pipes are superior to metal products. Some manufacturers claim that their products will last at least 50 years.
• Installation technologies are quite well thought out and practically tested. They are simple and do not require heavy welding equipment, gas cylinders, hoses or transformers. Installation of polypropylene elements can be compared to a children's construction set, only for adults. All products and tools, simple and light, appearance It is intuitively clear what to attach and where. A person who does not have special professional skills can assemble everything with his own hands with a high level of quality.

Technologies for installing polypropylene pipes

• The elasticity of the material allows it to better withstand the freezing process in comparison with metal products.
• Polypropylene parts do not rust and do not accumulate scale during operation. The pipes are neutral to the chemical components of the coolant and do not enter into a chemical reaction with it.
• The cost of polypropylene products is significantly cheaper than metal and especially copper.

Disadvantages and methods for eliminating them

• The main disadvantage of polypropylene pipes is their high expansion coefficient. At a coolant temperature of 100°C, 10 meters of pipe lengthens to 15 cm. This leads to deformation of the structure. In order to prevent destruction, flexible supports are installed and compensation loops are made. Later, pipes began to be used foil reinforced, which significantly reduced the expansion coefficient. Now the most practical pipes, reinforced with glass fiber: under the same conditions they extend by only 1 cm.
• Polypropylene products, especially connecting elements, are inferior to metal pipes in strength. It is not even correct to compare them: when subjected to strong impacts with hard objects, polypropylene is deformed and may collapse.

Choice

There are many models of polypropylene pipes. We will describe what can and should be used.

Mandatory requirement for a heating system - only heat-resistant pipes and connecting elements are selected that can withstand temperatures of at least 80°C.

They must be reinforced; there are three types:

• PPV foil-reinforced pipes along the outer diameter;
• PPV foil-reinforced pipes along the internal diameter;
• PPV pipes reinforced with glass fiber.

Pipe reinforcement with foil along the inner diameter

The best option is fiberglass reinforced pipes; they are soldered well and have a low expansion coefficient. Pipes reinforced at the outer diameter must be stripped of reinforced foil at the joints before soldering. This unnecessary problems and the likelihood of deformation. All listed options must withstand pressure of 6-7 atmospheres.

It is advisable to use couplings, rotary fittings, and valves without metal elements. Connections are made only by welding, with both ends inserted into the coupling - this is the most reliable and durable connection.

Control valves: couplings and fittings

It is recommended to buy pipes and all components from European manufacturers, for example, Germany, the Czech Republic. Turkish production is still far from perfect: uneven reinforcement layer and wall thickness along the outer and inner diameter.

Installation

If you want to do a high-quality installation yourself, you should start by drawing up detailed diagram indicating not only the locations of the main elements, but other parameters:

• pipe laying routes;
• places of connections, turns and connections;
• pipe diameters;
• number and location of couplings, fittings and valves.

Heating layout in the house

The common pipes are chosen with a large diameter, and the radiator bends have a smaller diameter.

Based on this data, you can accurately calculate what you need to buy and which ones. Consumables, tools will be required.

For a private home, the best option for assembling a heating system is considered to be “Upper Spill” - a gravity-flow type scheme. It is simple and can be done with your own hands. There is no need to install forced pumps to circulate coolant fluid. You should not increase the diameter of the common main pipe, this will only slow down the circulation and increase heating costs. The optimal diameter for these purposes is 63 mm.

After purchasing all the necessary materials, installation occurs. It begins with cutting pipes with special scissors to pre-calculated sizes. Then the pipes are laid out according to the laying route diagram. It is important that the ends of the cuts are 90 degrees.

The soldering apparatus must be placed horizontally on the surface, with a fat-free nozzle selected according to the size of the pipe. Preheat it to 360°C. At the same time, the connecting surfaces are heated in the working hole of the soldering iron. Then we insert the pipe into the fitting.

The parts must be heated to room temperature before soldering. If you solder a fitting brought in from the cold, the structure of the plastic will be damaged due to a sharp temperature change. This connection will not last long.

Soldering points on pipes and fittings must be thoroughly cleaned and degreased, using vodka or alcohol with water 1:1. At the end of the work, you need to make a connection: fill the system with water and check its functionality for two hours at a maximum temperature of up to 90 degrees.

Tools

• scissors for cutting polypropylene pipes;
• electric soldering iron with attachments for welding polypropylene pipes;
• hammer drill for drilling transition holes in walls;
• tape measure, marker;
• pipes, couplings, fittings, adapters, crosses, everything according to the previously compiled list.

Soldering pipes. Video

You can watch about the mistakes a novice master makes when soldering polypropylene pipes in this video. It also contains current ideas for optimizing this process.

Polypropylene pipes have become actively used for the installation of heating systems in private homes. Consumers are attracted by the affordable price, ease of assembly, which can be done by hand, high quality and reliability of the work performed. This largely explains their popularity these days.

Wanting to make their home more comfortable and cozy, owners often face the problem of creating or upgrading a heating system with their own hands. This task is quite within the power of everyone. Let's take a closer look at where to start and how to act so that your water heating served reliably for many years.

Most owners today choose polypropylene pipes and fittings for heating a private home. And this is quite natural, since polypropylene has a large number of advantages over other materials at a relatively low cost and ease of installation.

Polypropylene pipes and fittings

Water heating is characterized by relatively high temperature coolant, which can cause significant thermal elongation of pipelines. In this regard, ordinary polypropylene cannot be used; only reinforced polypropylene pipes for heating are used. To reinforce polypropylene, fiberglass or aluminum is used.

Polypropylene pipe with fiberglass

The reinforcing layer has a significantly lower degree of linear expansion than polypropylene and prevents the occurrence of such undesirable phenomena as bending and sagging of pipelines when heated.

Sagging of heated pipelines

In addition to being unsightly from an aesthetic point of view, temperature deformations can create serious stresses in pipelines and cause cracks in building structures or coolant leaks.

Strengthening polypropylene pipes for heating with the introduction of an internal aluminum layer can be done in 3 different ways:

• A layer of solid metal is inside the polypropylene pipe;
• A layer of solid metal is located at the very surface;
• A perforated layer of aluminum is located at the surface of the material.

Soldering is used to connect polypropylene elements. The end of the pipe and the required fitting are heated with a soldering iron, and then rigidly connected to each other, creating a reliable, uniform joint after solidification.

The reinforcing aluminum foil is removed at the joint. If the metal is near the surface, then it is cleaned using a special stripper or a knife, and if it is inside, then the inner layer is cleaned using a trimmer. This ensures a reliable connection between the pipe end and the fitting and protects the aluminum from possible damage and delamination during operation.

Before you begin to independently install a heating system with polypropylene pipes, be sure to carefully study all the recommendations and complete several training rations!
It is better for a novice installer to choose fiberglass-reinforced polypropylene pipes for heating his home, since they do not require processing before soldering, which speeds up the work and eliminates the need to purchase additional tools.

In addition, they clearly win in terms of cost-quality ratio. You just need to take into account the slight increase in length when heated for pipes with fiberglass fiber. When crossing walls, pipes are enclosed in sleeves that allow the polypropylene pipe to move freely, and between internal corners walls and pipeline turns leave space for compensation stroke during thermal expansion.

Without professional skills, it is quite difficult to understand the wide range of brands and decide what is best to install your water heating from. Therefore, as practice shows, it is better to trust the experience of the majority and give preference to the most common well-known brands. More expensive pipes, in addition to increased reliability, also have a very important advantage for a beginner - they are usually easier to solder, they forgive minor flaws when joining elements.

Thus, a glass fiber reinforced polypropylene pipe from a well-known manufacturer is ideal solution for installing a heating system for a private house with your own hands.

The marking of the pipe must contain the inscription PN 25. The diameter of polypropylene pipes for heating is selected by calculation, proportional to the required coolant flow according to the heat load and the selected heating system design.

Advantages and disadvantages of polypropylene pipes

A heating system made of polypropylene pipes has the following advantages:

1. Affordable price and quality.
2. Smooth inner surface pipes allows coolant to pass through minimal losses pressure.
3. Reliability.
4. Resistant to corrosion and water hammer.
5. Good maintainability.
6. High heat and sound insulation.
7. Great elasticity, providing resistance to freezing of water in the system.
8. Environmental friendliness.
9. Working pressure up to 10 atmospheres.
10. The temperature of the transported liquid is up to 95 °C.
11. Estimated service life is more than 50 years.
12. Possibility of hidden installation in walls and floors.
13. Simplicity of assembly allows you to quickly and easily install the heating system of a private home with your own hands.

To be fair, it is worth noting the minor disadvantages characteristic of polypropylene pipes:

• High coefficient of linear expansion;
• The need for protection from sunlight, because they negatively affect the structure of the polymer;
• When heated to 175 °C, polypropylene melts;
• Purchasing from an unverified manufacturer may lead to unexpected surprises due to a significant decrease in all indicators due to low-quality raw materials and violations of production technology.

Heating system diagrams

If apartments usually use a dependent heating circuit powered by a heating network, then in a private house you have to think about installing your own heating boiler and how to connect it. For independence from external factors and the ability to independently set a comfortable temperature in the premises comes at the cost of additional hassle when arranging a heating system and the cost of boiler equipment plus components.

An independent scheme for organizing heating of a private house involves, in addition to laying pipes, also installing a heating boiler. The most economical option today is to combine electric with solid fuel boiler. Due to the nature of this equipment, the following precautions must be taken:

1. Due to the release of a large amount of heat during the combustion of wood, it is advisable to use metal pipes for piping a floor-standing solid fuel boiler, followed by a transition to polypropylene using special couplings.
2. For reliable operation of an electric boiler, it is necessary to ensure a constant voltage in the network.
3. The piping scheme for a floor-standing solid fuel boiler must necessarily include the presence of an expansion tank and a safety group.

Depending on the tightness, the heating system can be open or closed type. The first implies the presence in the attic of an open container for the coolant that expands when heated, the second has a special closed tank with a membrane near the heating boiler.

An open system can only be used with natural coolant movement. In this case, it moves by gravity due to gravitational pressure. In a closed type system, the transfer of working fluid is ensured using circulation pump.

Despite the apparent cheapness of heating without a pump, the gravity-flow scheme will require significant costs for pipes, since it only works well with large diameters and, accordingly, requires significant capital costs for pipes. In this case, only open installation is possible.

Heating schemes with forced circulation in practice turn out to be more economical and aesthetically pleasing, are better adjustable and provide more high efficiency. A closed-type water heating system with a pump operates more stable than a gravity-fed one. It always ensures constant pressure and good circulation, and therefore uniform heat distribution.

An open system can only be justified for small houses and in areas with power outages. Before you create water heating for a private house with your own hands, you need to decide on the circuit diagram, circulation method and pipe layout, carefully design everything and draw up the necessary drawings.

The efficiency of heating circuits, ease of use and comfort of residents depend on the correct choice at the design stage.

Based on the type of wiring used, there are 3 main heating schemes made from polypropylene pipes in a private house: single-pipe, collector and two-pipe.

Single-pipe scheme

The cheapest and easiest to implement heating wiring diagram. The coolant in a single-pipe heating system consistently fills all heating devices. At the same time, each subsequent radiator receives increasingly cooled water, and the heat is not distributed evenly. In closed systems, where the pump provides good circulation, this drawback is almost unnoticeable.

Single-pipe heating system, closed circuit

As practice shows, under certain conditions it is possible for the water to completely cool down even before entering the last heating radiators and, as a result, rooms remote from the boiler remain cold.

If you need reliable water heating that operates reliably and at a comfortable temperature in all rooms, then a single-pipe heating system should be avoided. It can be justified only for small houses, and the first to be connected along the flow of the coolant are the living rooms, and then the technical premises.

Collector circuit

A more complex and materials-intensive water heating scheme, but one that allows for uniform heat distribution, ease of operation and high reliability of the system. At the outlet of the heating boiler or at each branch from the riser, a collector comb is installed, to which horizontal branches or individual devices are connected.

The most relevant use of this scheme for connecting devices is in large cottages with complex branched systems. It allows you to adjust the temperature and pressure parameters for each branch or device separately.

If your home uses a combined heating scheme, that is, a combination of classic radiator heating with heated floors, then you will definitely make the right choice by choosing a collector scheme.

Provides parallel connection of heating devices to the supply and return pipelines. Each radiator is independent from the others and receives coolant at the inlet of almost the same temperature.

In an emergency, you can turn off one or more devices without compromising the functionality of the system. The two-pipe installation scheme allows for hidden installation and easy hiding of pipelines in the floor. In most cases, this particular heating scheme for a private house is the most optimal.

Two-pipe heating circuit with bottom wiring

In a private house, both horizontal and vertical piping can be used. Vertical wiring is used in houses with 2 or more floors. It is most typical for large cottages.

The coolant moves along the risers from floor to floor. It is possible to organize heating with bottom and top wiring, depending on the location of the supply pipeline relative to the radiators. The heating scheme for a two-story house can also be carried out with horizontal wiring, when horizontal branches radiate from one riser throughout the house on each floor. Heating scheme one-story house will definitely be horizontal.

Horizontal layout

The horizontal connection diagram for radiators in modern private homes is the most common. It allows you to make a heated house comfortable both in terms of thermal conditions and aesthetics. Individual devices and branches can be turned off without damaging the main system and adjusted as needed.

The heating concept can be one-pipe or two-pipe. Depending on the method of laying, there are perimeter and radial.

Perimeter wiring

Perimeter wiring involves laying pipes along the walls around the perimeter of the apartment; hidden installation in the floor structure is also possible. Such a water heating system is convenient to install both during new construction and during reconstruction. The main disadvantage is the significant length of the pipelines and the difficulty of ensuring the ability to drain water from the system.

Heating scheme with horizontal perimeter wiring

Radial wiring provides for a separate connection of each radiator to a common collector using the shortest route; the device connection diagram resembles the sun's rays. It allows the user to individually configure each device and provides easy hydraulic balancing.

This heating system scheme is convenient for new construction; the pipes are laid on the rough surface of the floor and filled with screed. The disadvantages include the difficulty of repair, since in the event of an emergency it is very difficult to get to the pipelines. The consumption of pipes during beam distribution is greater than in other options, but this is compensated by a reduction in their diameters. It is this piping layout that is typical for most modern cottages.

conclusions

When starting to install a heating system made of polypropylene pipes in a private house, carefully study the polypropylene soldering technology and analyze everything possible schemes water heating, determine the required thermal loads, draw up plans and 3D drawings.

Try to first consult with a specialist in the field of heating engineering and agree with him on the design of the future system. By enlisting the support of an experienced person in technical matters and having carefully prepared, you can easily cope with installing a water heating system for a private home with your own hands.

In the arsenal of the plumbing industry today, significant positions are occupied by polymer and combined products, which replaced cast iron and steel.

Installation of heating from polypropylene pipes is a proven and reliable technology that occupies one of the leading positions in the arrangement of water supply and heating.

Advantages of polypropylene pipes

Installation of heating from polypropylene pipes is considered one of the cheapest ways to arrange a system, since the price of work and materials is quite affordable. Polypropylene is also not inferior, and sometimes even superior, in quality to other materials. The service life of pipes of almost any class is 50 years, provided they are used in standard (according to GOST) conditions.

Advantages:

1. Light weight. Facilitates work and also reduces the load on supporting structures.
2. Durability.
3. Smooth walls prevent blockages from forming.
4. The cost is one of the lowest among heating systems.
5. Elasticity - will not burst when the water inside freezes.
6. Resistance to high temperatures, which allows them to be used in a number of heating systems.
7. No stray currents.
8. Easy to install. The cost of welding (soldering) equipment is quite low.
9. Soundproofing. You can't hear water hammer or water movement.
10. Low thermal conductivity. Allows you to do without insulation.
11. Aesthetics. They look neat.

Among the disadvantages, elasticity can be noted: unlike pipes made of cross-linked polyethylene, these cannot be bent; the bending angle is possible only within the framework of existing fittings.

Another feature is the large linear expansion, which makes it difficult to use in closed options, that is, in the walls, and also necessitates the use of expansion joints in open ones. In simple words: when heated, pipes expand, which can lead to both deformation of the wall material and breaks in the pipe itself.

Classification of polypropylene hoses (4 classes)

Often four classes of hoses are indicated, since the third is practically not used, but GOST specifies five classes for polymer products.

Polypropylene hoses are divided into classes according to heat resistance and operating pressure values:

• 1 class- hot water distribution systems up to 60 °C;
• 2nd grade- hot water distribution systems up to 70 °C;
• 3rd grade- underfloor heating, low temperature radiators up to 50 °C;
• 4th grade- underfloor heating, low temperature radiators up to 70 °C;
• 5th grade- high temperature radiators up to 90 °C;

There is also a class “XB” - intended for cold water supply.

It is assumed that the system will operate in certain temperature conditions, which differ for each season and off-season. For example, for high temperature radiators, the system should last 50 years: 14 years at 20°C, 25 years at 60°C, 10 years at 80°C and 1 year at 90°C. This means that in a region with increased heating season service life will be reduced.

The emergency temperature for classes 1-2 is 95 °C, for class 3 - 65 °C, for classes 4-5 - 100 °C. That is, pipes can withstand significant excess operating loads for a short time, up to 100 hours over the entire period.

The maximum working pressure of thermoplastics should be:

• 0.4 MPa;
• 0.6 MPa;
• 0.8 MPa;
• 1.0 MPa.

Heating system diagrams

The scheme option depends on the technical characteristics of the object, as well as the financial capabilities of the owner. The same object can be equipped in any of the ways.

Three heating schemes are most commonly used:

• single-pipe;
• two-pipe;
• collector

The first is the simplest, the second is more complex, but also more effective, the third is used for large wiring, for example for arranging heated floors or walls.

Single-pipe

Initially, if it was necessary to provide centralized heat large residential areas, then this type of piping was used in order to save materials and simplify installation.

Such a system has one riser and one circuit, and the coolant supply is a closed system in which everything technical units connected in series. It can be vertical or horizontal. The first is used in multi-apartment buildings, the second is suitable for private houses.

Previously, the main problem with such a scheme for the consumer was that the further the radiator is from the source, the colder it is, since heat is wasted as it is delivered. The accompanying difficulties in regulating and distributing temperature also did not add to its popularity.

The single-pipe system did not take into account many factors of loss of both heat and resources, the costs required to deliver it to the consumer. IN apartment buildings This arrangement does not allow you to control and maintain the same pressure in all elements of the system. A pump is needed, however, it cannot provide consistency, which leads to water hammer and leaks.

In the event of a breakthrough, the coolant must be replenished, which also leads to additional costs.

If one battery fails without a valve system, the supply of coolant to all radiators of the system is stopped for the period of repair.

For normal operation in a private home, an expansion tank is required, which performs the functions of stable temperature balancing. The technical room and this container are located in the attic.

Positive aspects:

1. New technologies have eliminated the problem of uneven temperature distribution. Modern radiators are equipped with thermostats and thermostatic valves, which significantly eliminates heat loss from delivery to distant batteries.
2. The use of valves, ball valves and bypasses allows you to repair an individual radiator without shutting down the entire circuit as a whole.
3. Installation of such a scheme is simpler and less expensive, moreover, it requires half as many pipes, and accordingly the number of fittings is reduced. Using modern innovations, you can eliminate most of the disadvantages and save a lot, which makes this option extremely attractive in private housing construction.

Two-pipe

Unlike a single-pipe system, in a two-pipe system the coolant is supplied to each radiator separately through one riser, and through the second it returns back to the heating boiler. That is, the battery is served by two pipes - supply and return.

The disadvantage of such piping is a doubling of the number of pipes, as well as a significantly larger number of fasteners, fittings, and valves. Which naturally affects the costs of both materials and installation.

Now to the pros:

1. Ensures uniform heat supply to all radiators.
2. Allows you to avoid pressure losses. If a less powerful pump is required, the water can circulate by gravity.
3. If necessary, it is possible to repair a separate radiator without damaging the heating.

It is possible to use associated and dead-end water movement in the system. The first involves installing radiators of the same power, otherwise it is necessary to install thermostatic valves. It is used in long-distance pipelines and provides ideal hydraulic balancing. The second, accordingly, is used in short harnesses.

It can be vertical or horizontal. The first is more often used in multi-apartment buildings, the second - in private houses (like a single-pipe system).

In private buildings, when using horizontal wiring, it is recommended to install a Mayevsky valve in each radiator, which is necessary for bleeding air.

In addition, a two-pipe system can have an upper and lower piping, respectively, the first involves placing a hot water supply riser on the ground floor, in the basement, the second requires placing the distribution line in the attic.

Collector

A metal comb with leads for connecting pipes and devices is called a manifold. Such a system, in fact, is also a two-pipe system; the supply to the comb is carried out from one common pipe, as is the return of the cooled coolant through the return manifold. The difference is that here the coolant is supplied through a separate pipe to each radiator or to floor and wall heating.

This scheme requires an expansion tank with a volume of at least 10% of the total volume of all heating devices and a circulation pump.

The manifold cabinet should be located at approximately equal distances from each radiator.

Both bottom and top feed are also possible here. The first is more preferable, as it allows you to hide the pipes in the floor.

Each circuit is an independent hydraulic system with its own shut-off valves, which allows you to turn off each of them without damaging the rest of the network.

Advantages:

1. Uniform heat distribution, the ability to adjust the temperature of each radiator without compromising the others.
2. The efficiency of the system is higher, since the coolant is supplied directly to each individual heating device.
3. High efficiency makes it possible to use pipes of smaller diameter and a boiler of lower power, which reduces both one-time costs for the purchase of materials and equipment, and constant costs for heating and the purchase of fuel.
4. The possibility of using heated floors makes it possible to heat without the use of traditional radiators, which is practical and aesthetically pleasing.
5. Allows you to repair each individual element without reducing the efficiency of the rest of the system.
6. Ease of design: no need to make complex calculations.

Disadvantages can be divided into two categories: cost and practical. The construction of a collector is significantly more expensive than other options.

You will need:

• fitting;
• combs;
• shut-off valves;
• circulation pump;
• expansion tank;
• collector cabinet;
• a large number of pipes.

In addition to cost, there are other disadvantages that you should be aware of, but which, nevertheless, are not critical.

Practical disadvantages:

1. All radiators must be equipped with Mayevsky taps, since airing of the collector system is a common phenomenon.
2. Despite the simplicity of the project, installation of such a system is labor-intensive and costly.
3. Space is required for the manifold cabinet, which should ideally be located in the center of the entire system (in a spatial sense).

System diagrams by type of coolant supply

The main problem of the correct functioning of the radiator is the need to organize uniform distribution of coolant throughout all its sections. Warm water has a lower density, so it tends to rise in the battery, displaced by cold water - with a higher density.

The coolant supply can be carried out in many ways.

Common options:

• bottom eyeliner;
• top;
• diagonal;
• lateral.

Visually, everything looks as it is called: with a bottom connection, the pipes are connected to the radiator from below, with a top connection - from above, and so on.

However, everything is not so obvious in the design of the radiator itself. To control the movement of hot water along the required route, various types of jumpers are used.

Different connection methods also involve the use constructive solutions the entire heating system. In some cases, an expansion tank is needed, in others - a circulation pump, in others - both. Depending on the vertical or horizontal system, Utility room must be installed above or below the heated room.

With top liner

The radiator has upper and lower horizontal collectors and vertical channels that connect them.

When connecting pipes at the top of the radiators, there is a danger that warm water will only heat the upper collector. In order to avoid this, a jumper is placed in front of the last rib. Thus, the coolant, before entering the return, is forced to pass through all sections. Essentially, this jumper transforms the top connection into a diagonal one, which increases heat transfer.

If there is no jumper, practice diagonal strapping: the pipe supplying the coolant is connected at the top, and the return pipe at the bottom.

With bottom liner

The bottom harness is considered the simplest scheme. The boiler is installed in the basement or basement, the main supply pipe goes up to the expansion tank, from which the booster or starting section is built. The height of this section of the pipe should be located at a distance of at least one and a half meters above the first radiator. The supply pipe is connected at the bottom of the battery, and the return pipe is connected on the opposite side. The remaining radiators are connected in series in the same way.

If natural circulation is assumed, a slope must be ensured when laying pipes. The last radiator in the chain should be higher than the boiler, but no more than three meters.

It is optimal to install a circulation pump, as well as the use of bypasses and shut-off valves on each battery.

It is worth considering that in the event of a power outage, the pump will be turned off, and a complete exchange of coolant will be ensured by natural circulation, and in this case the slope of the pipes is intended to improve it.

Bypasses and a valve system will allow you to avoid shutting down the entire system if one of the radiators fails. In this case, only the emergency section will be disabled.

In addition, it is worth remembering the need to install Mayevsky taps or automatic air vents.

Which pipes to use

Almost all polypropylene products are suitable for cold water supply, but with hot water the situation is somewhat different.

In order to use pipes for the delivery of drinking water, they must have a certificate of conformity. For hot water supply, first and second class hoses are used with operating temperatures up to 70 degrees. For heating and arrangement of heated floors, special products are used that have reinforcing and anti-diffusion (protecting against oxygen access) layers.

The pipes are marked accordingly.

It is necessary to take into account some features. For example, polymers are not used when combined with solid fuel boilers. At least one and a half meters of the initial supply and return sections must be made of copper or steel pipes.

Prices for polypropylene pipes from different manufacturers

How to choose the right diameter

To accurately select the diameter, a hydraulic calculation of the system is required, however, in houses up to 250 m² you can do without it.

The diameter directly depends on the total power of the radiators, and it should be understood that different sections of pipes serve part of the system, and not its entirety, so the supply often has a smaller diameter than the connection and return pipes.

For accurate balancing, it is still necessary to use a hydraulic calculation, with the help of which the diameter and length of different sections, as well as the radiator valves and circulation pump are selected.

As a result of the calculation, the following data is obtained:

• coolant flow for the entire system, kg/s;
• pressure loss in the system;
• pressure loss from the boiler (pump) to each radiator.

The coolant flow rate is equal to the ratio of the heat loss of the building to the product of the heat capacity of water and the temperature difference between the boiler supply and return.

The speed of movement of the coolant is equal to the ratio of the flow rate through a section of pipe (kg/s) to the product of the density of water and the cross-sectional area of ​​the pipe in square meters.

The pressure loss is equal to the product of the specific friction losses in the pipe and the length of the pipe section. Friction information should be provided in the manufacturer's reference literature.

Resistance losses on fittings, fittings, and equipment are also calculated. The coefficient is indicated by the manufacturer of each fitting. To calculate, the coefficient is multiplied with the density and speed squared, divided by two.

As a result, the resistances of all sections are summed up and compared with the control value.

If independent calculation is difficult, contact a specialist.

Installation features

Installation begins with installing the boiler. Many manufacturers recommend carrying out this work with the assistance of specialists. It is advisable to have a document confirming that the installation was carried out by a specialized organization, otherwise you may lose the manufacturer’s warranty.

Strapping sequence:

1. Radiator installation locations are marked.
2. If necessary, a hydraulic calculation is made.
3. The boiler is equipped with a riser, an expansion tank and an accelerating manifold.
4. Radiators are installed in the designated locations.
5. Places for inserting tees for joining radiators, installation locations for taps and shut-off valves are outlined.
6. A circulation pump is installed.
7. As the circuit is being assembled, if the pipes are sewn into the walls, they must be insulated.
8. Radiators are connected to the circuit.

After assembling the system, control tests are carried out - the system is filled with either water or air and checked for leaks or pressure drop. If everything is in order, a test run is carried out using coolant.

Pipe connection methods

There are several ways to solder pipes. The most commonly used option is the socket version: when the pipes have different diameters, that is, at the connection point, one is inserted into the other. The parts must be preheated with a special soldering iron. In the same way, welding occurs using couplings, as well as connecting with a fitting.

Often the socket connection is secured using an adhesive or an O-ring retaining ring.

With end brazing, both elements have the same diameter; in this case, soldering occurs in a butt manner. Melted to a state of viscous fluidity, the ends are connected to each other under pressure and maintained until completely cooled.

When butt welding special equipment is required, since joining the pipes evenly and holding them under uniform pressure manually is extremely problematic.

In both the first and second cases, equipment can be rented, since it is not cheap.

How to solder pipes

Pipe welding is carried out using a soldering iron, the fundamental design of which is practically no different from a conventional one. This device is equipped with special nozzles for different pipe diameters.

The cost of such units starts from approximately 1,200-1,300 rubles (20 US dollars), more complex models will cost 4,000-5,000 rubles (60-70 US dollars).

Welding order:

1. The pipes are cut with a pipe cutter. The edge should be smooth, without roughness or debris.
2. A corresponding nozzle is installed in the soldering iron.
3. Both elements being connected are heated simultaneously.
4. They are inserted into each other until they stop, turning is not allowed.

Polypropylene cools quite quickly, so some skill is required, and it is not necessary to hold the connected parts for a long time.

Methods for laying pipes in walls

Since materials can expand when heated, insulation is used when laying in walls or screeds.

In closed areas, a minimum number of connections is highly desirable, since if a leak occurs in such an area, it will be necessary to eliminate not only the problem itself, but also the forcedly dismantled layer of the wall or screed. In such areas special hatches are equipped.

Also, these places are insulated with mineral wool, glass wool or other insulation. This prevents them from fogging up. It is necessary to leave a gap between the walls of the slot in the wall and the pipes.

The slots are made with a hammer drill or grinder. The material between them is removed with a chisel or, again, with a hammer drill. After this, you can insert the pipes and test them for leaks. Then you can close them cement mortar. Instead of cement, it is allowed to use gypsum.

DIY installation

In private homes, installation is often done independently. To do this, you need to draw up a project, acquire the necessary materials and tools.

Drafting

The project is essentially a master plan and a guide to action. Allows you to determine in a timely manner what materials and in what quantities will be needed.

During the development process it is necessary to consider:

• type and number of pipes and manifolds;
• number of pumps and filters;
• number of water points;
• volume of the water heater and expansion tank;
• the location of all elements of the system, the distance between them.

In order to determine the dimensions, you will need a drawing of all rooms and, if necessary, sections of the external part of the structure. The project is drawn up on a single scale.

Required tools and materials

In accordance with the project, materials and their quantity are determined.

Basic:

• tubes;
• fitting;
• shut-off valves, valves;
• radiators;
• expansion tank;
• pump.

In addition, you will need materials for fastening and finishing, that is, various kinds of hardware, clamps, as well as construction primers, putties, and solutions.

You will need two sets of tools: for fastening to the walls and for connecting the system elements. The first set will depend on the materials of the walls, the need to sew up pipes and the degree of readiness of the premises.

Common construction tools:

• perforator, drill;
• Bulgarian;
• roulette, level;
• hammer;
• screwdriver (screwdriver).

Connection tools depend on how they are installed. For welding you will need a soldering iron and nozzles. To connect fittings, radiators and other elements, you will need adjustable wrenches.

Pipeline installation

The pipeline is one of the most important elements of the entire system. It must also be displayed in the project.

Installation sequence:

1. Marking.
2. Installation of fasteners, clamps, gutters.
3. Connecting areas.
4. Insertion of fittings, valves.
5. Installation to radiators.

To ensure reliable pipeline connections, installation work must not be carried out at room temperatures below 5 C.
All components (pipes, fittings, valve fittings) must be free of contamination and damage
Therefore, it is important to observe safety precautions when transporting and storing the material.
It is important to keep open flames away from the material. Otherwise, the pipes and fittings will become deformed and will be unusable.
If it is necessary to intersect pipes, you need to use special (triple, cross) fittings.
Where there should be a threaded connection, threaded fittings are installed
It is unacceptable to cut threads on polypropylene pipes with your own hands.
To ensure the tightness and tightness of the threaded connection, use flax tow or FUM tape.

Materials and tools

Polypropylene pipes PN 10 are intended for cold water supply, PN 20 - for hot water with temperatures up to 80o.

PN 25 pipes, reinforced with aluminum foil and withstanding temperatures of 95 degrees, have been developed especially for heating in a private house with polypropylene.

Polypropylene pipes PN 25 have the following characteristics:

• Melting point - 150 degrees
• Maximum operating pressure - 25 atm
• Density - 0.9 g/cu. cm
• Coefficient thermal expansion- 0.15 mm/mmS
• Thermal conductivity - 0.24 W/mS
• Outer diameter - 21.2 - 77.9 mm
• Inner diameter - 13.2 - 50 mm
• Wall thickness - 4 - 13.3 mm

The advantages of polypropylene pipes for heating are:

• Resistance to corrosion and scale deposits on internal walls
• Pipes do not burst when water freezes
• Low cost
• Light weight
• Plastic
• Resistance to temperature changes
• High level of sound insulation
• Long service life - up to 50 years

Disadvantages include low melting point and exposure to ultraviolet rays.

To install polypropylene heating, you will need the following special tools:

• Soldering iron with a set of nozzles for connecting pipes
• Plastic pipe shears or roller pipe cutter
• Deburring and chamfering cutter
• Shaver for removing foil

Every home must have heating. However, summer houses are an exception. For example, frame garden houses, which are designed for relaxation during the hot season. Therefore, it is not worth installing a heating boiler, because... summer temperature will warm up such a house itself.

If you plan to relax only in the summer, then you can build such a garden house with your own hands. Read about how to build such a wonderful building here.

Pipe selection

Before making a selection, you should carefully analyze the specifics of the room, decide on the type of heating system, and also take into account the fact that certain skills and knowledge are required when installing this or that pipeline fittings, consider whether you can do everything yourself or will have to seek help from a specialist .

Types of polypropylene pipes: (1- with aluminum reinforcement, 2- with fiberglass reinforcement).

Manufacturers provide a wide range of products for heating installations made from various materials: metal, metal-plastic, polypropylene, each of which has its own positive and negative sides.

Today, both specialists and non-professionals recognize polypropylene pipes as the most popular and optimal option.

Metal pipeline products are the most expensive, susceptible to corrosion, which, accordingly, reduces their service life, and there are certain difficulties in assembly.

Metal-plastic pipes are well known for their low cost and easy installation process, but they are not strong and durable.

For heating and plumbing systems the best option is polypropylene pipes, especially when installing it yourself. It should be noted that, depending on the purpose of use (heating, hot or cold water supply), pipeline fittings vary significantly in technical characteristics and in no case can be interchangeable.

The wide scope of use of polypropylene pipes is justified by a large number of advantages: reliability and durability (up to one hundred years of operation); corrosion resistance; resistance to chemical influence; protection from mineral deposits; easy installation and subsequent repairs.

And yet this material also has a drawback - low fire resistance.

To make a choice which polypropylene pipes are needed for the heating system, you should choose a diameter that does not affect the water pressure, but also not too wide, since then you will have to overpay unreasonably.

Disadvantages and methods for eliminating them

• The main disadvantage of polypropylene pipes is their high expansion coefficient. At a coolant temperature of 100°C, 10 meters of pipe lengthens to 15 cm. This leads to deformation of the structure. In order to prevent destruction, flexible supports are installed and compensation loops are made. Later, foil-reinforced pipes began to be used, which significantly reduced the expansion coefficient. Nowadays, the most practical pipes are reinforced with glass fiber: under the same conditions they extend by only 1 cm.
• Polypropylene products, especially connecting elements, are inferior to metal pipes in strength. It is not even correct to compare them: when subjected to strong impacts with hard objects, polypropylene is deformed and may collapse.

Heating system diagrams

Select the optimal pipe layout for self-installation of polypropylene heating. In the future, you will receive recommendations for connecting individual elements and place them in accordance with the chosen plan.

Single-pipe scheme

Single-pipe scheme

The simplest method of arranging a heating system. In accordance with this wiring method, each battery installed further from the heating unit will heat up to a lower temperature compared to the previously installed battery.

This method makes it possible to reduce the consumption of materials for the arrangement of the heating system. However, the heating efficiency will be low, because The temperature distribution with such pipe routing is uneven.

In view of this, you should try to refrain from a single-pipe pipe routing scheme.

Collector circuit

Collector circuit

To equip a heating system according to this scheme, you will have to spend more materials, however, the basic operational properties of such heating will be much higher.

Heat distribution throughout the rooms will be fairly uniform and high quality.

Two-pipe system

Two-pipe system

The most optimal method of arranging a heating system. The pipes are laid into the floor or into the walls of the house around the perimeter. Two-pipe heating is best suited for heating a home. Therefore, experts recommend giving preference to this particular pipe routing option.

Advantages of polypropylene

Pipes and connectors

• the heating system made of polypropylene is not subject to corrosion;
• more reasonable price than metal analogues;
• there are no reactions from exposure to acidic or alkaline environments;
• there is no accumulation of deposits on internal surfaces;
• there are no significant changes in coolant temperature, depending on the microclimate of the room, due to the low thermal conductivity coefficient;
• the movement of the coolant is not accompanied by noise;
• due to the property of plasticity, it is possible to make bends in the required places;
• changes in coolant temperature do not affect the design in any way;
• durability and ease of installation.

The main advantages of polypropylene pipes

If we list all the advantages of polypropylene pipes, it is worth noting their high level of quality, as well as their affordable cost. Heating systems created from these elements will serve their owners well for decades. The use of unique technologies in the manufacture of polypropylene pipes allows us to speak with complete confidence about the high strength of the products.

Polypropylene pipes do not yield during operation negative influence corrosion, and also perfectly resist mechanical influences from the outside. Dirt and impurities will not accumulate on the pipe walls. Consequently, the water will be clean and transparent for a long period of time.

As for installation, this is another advantage inherent in polypropylene pipes. Installing polypropylene heating with your own hands is not difficult.

Heating system planning

The main components of the system under consideration include the boiler, the pipes themselves, radiators (batteries) and fasteners.

Heating planning scheme for a private house.

Heating elements (or boilers) vary in fuel types and characteristics. Their installation is recommended in a specially designated area (room, outbuilding) with good ventilation and a gas sensor. The boiler must be installed below or at the level of the lowest point of the heating system, in no case higher.

It is necessary to develop a pipe installation project that includes diagrams in all rooms where the heating installation will be organized. If you are planning to do it yourself, you should remember that you will need additional components, such as angles and angles of rotation, couplings and various adapters. These points must be reflected in the project at each site where these parts will be used according to the plan. In addition, the diagram should indicate the installation locations of radiators and indicate the length of pipes between them.

You should take care of the fasteners for attaching the pipes. Fastening elements are selected in accordance with the type and diameter of pipes, the weight of radiators (batteries).

There are several options for constructing a heating system made of polypropylene. First of all, there are systems with top and bottom spill.

The first method involves the principle of gravity movement of water. In this case, there is no need to install a circulation pump, since the water will flow through the pipes on its own. This type of heating system is effective in cases of frequent power outages, when the use of a pump is excluded.

Bottom-spout heating systems usually involve radial wiring and the use of a pump to increase water pressure. In this case, it becomes possible to use pipes with a smaller diameter, which, accordingly, allows you to save a little.

The next classification option is the division into one- and two-pipe systems with side and bottom connections to radiators (batteries).

Existing types of polypropylene pipes and their characteristics

Today, manufacturers offer a wide range of polypropylene products. And before purchasing pipes, you should understand their markings and properties.

There are several categories of such products:

PN-10 - available with an internal diameter of 16.2-90 mm, external diameter - 20-110 mm; For such pipes, thin-walled polypropylene is used (its thickness can be 1.9-10 mm), designed for operating pressure in the system up to 1 MPa and temperature up to 20 0C, therefore it is not used for heating systems.

• PN-20 - such products can have an external/internal diameter of 16-110 mm and 10.6-73.2 mm, respectively; the thickness of their walls is 1.6-18.4 mm; they are designed for operating pressures up to 2 MPa and temperatures up to 80 0C. Despite the fact that this category is considered universal, these pipes in the heating system can only be used in the return pipeline, provided that the coolant temperature does not exceed the previously specified value.

PN-25 is the best option for heat supply, distinctive feature which is multi-layered (the cross-section of the pipe consists of two layers of plastic, between which a thin layer of aluminum treated with glue is laid). Manufactured reinforced products can have an internal/external diameter of 13.5-50 mm and 21.2-77.9 mm, respectively, and a wall thickness of 4.0-13.3 mm. Such polypropylene is capable of functioning in a system with a coolant temperature of up to 95 0C and operating pressure of up to 2.5 MPa.

• PN-16 - can be used for pipelines with coolant temperatures up to 80 0C, however, this variety is not common and therefore is practically not used.

There is another variety: pipes reinforced with fiberglass, which are similar in quality to products with a foil layer. However, the first type has a slightly higher coefficient of thermal expansion, but their installation is somewhat simpler (category PN-25 requires preliminary removal of the foil on the area to be welded, if it is located close to the outer surface).

Do-it-yourself installation

When installing heating from polypropylene pipes, it is initially necessary to calculate the laying diagrams. With this installation, it is necessary to maintain the slope level to the lowest point of the system, because a tap or valve for draining is installed in this place. The length of pipe sections must be calculated for each section of communication. If the pipeline is divided into sectors that can be shut off individually at any time, the operation of the communication system will become significantly safer. All tools and installation parts must be at room temperature, for which they must be brought into the room immediately before the installation process. This action is necessary to prevent the material from cracking during operation. Using a felt-tip pen, it is necessary to apply marks according to the calculations performed on the measured pipe sections.

You need to cut the polypropylene with your own hands evenly and perpendicular to the surface with special scissors or a pipe cutter, after which the cut edges of the pipe are treated with an alcohol solution, and the rest of the dirt is removed with a dry rag. A nozzle with the appropriate cross-sectional diameter is installed on the soldering apparatus, which must first be degreased, the apparatus is installed horizontally and heated to 260 °C. Pre-prepared parts (pipe and fitting) are placed in the holes of the heater in a horizontal position, then the time is determined from the table and the parts are heated.

Then the parts are removed, the pipe is inserted into the fitting and a certain period of time is maintained for the elements to completely harden; twisting the parts during the hardening process is prohibited. This method of welding (soldering) parts is reliable and the most durable. Communication parts must be dry and clean when carrying out soldering work; if installation is carried out in a working (operating) system, then the water must be drained from the heating systems. To conduct trial tests of the heating system, you should not purchase water meters; instruments that show the deaeration of pipes are quite sufficient.

Choosing a heating source

Before you begin installing a polypropylene pipeline, you should decide on the heating source. This will affect general scheme heating systems and selection of additional elements.

Gas

It is considered very economical and environmentally friendly look fuel. However, it is appropriate to talk about efficiency only if the house is already gasified or is at least located near the main gas pipeline. Otherwise, connecting to a remote network will cost the owner a tidy sum.

The best option for installing a heating system using gas fuel is a modern wall-mounted gas boiler equipped with a complex necessary devices And defense mechanisms, providing maximum automation of system management processes.

Another advantage of this solution is the ability to abandon the chimney that is so common in private households. Modern gas boilers are equipped with a closed combustion chamber, the supply of oxygen and the removal of exhaust air from which is carried out through a thin tube.

Electricity

Another environmentally friendly way to heat a room, although more expensive than gas. To ensure the operation of the heating system, you will need a special boiler equipped with safety equipment, a pump for circulating coolant (depending on the chosen scheme) and an expansion tank.

Solid fuel systems

They are characterized by a higher coolant temperature at the boiler outlet, which imposes increased requirements on the organization of the safety system.

Advantages of polypropylene. Material and tool

Metal-plastic pipes are perfect for heating.

Internal almost mirror-like and slippery surfaces prevent various types of deposits. The price category of this type of pipe is much lower than its cast iron and metal counterparts. Polypropylene pipes are distinguished by their plasticity; you can make any turns and bends along the way of laying the heating main with your own hands. They react neutrally to almost any influence of an aggressive environment, are resistant to sudden temperature changes and have excellent performance characteristics. In addition, heating made from polypropylene pipes is distinguished by high sound insulation properties; water flows through the system almost silently. The long service life of polypropylene heating, easy assembly and production from environmentally friendly materials are additional advantages.
