How a gas boiler using bottled gas works, features of operation. Installing gas cylinders in a gas cabinet for a country house. Is it possible to connect a gas boiler to a cylinder?

In suburban villages it is not always possible to connect to the heat supply mains. In order not to freeze, it is not necessary to build a wood stove or buy a boiler; heating from a gas cylinder is a good alternative to all other heating systems. Let's consider what the technology is, the features of connecting and using natural fuel.

This is a system that uses liquefied propane gas or a mixture of propane and butane as a coolant. Heating with gas cylinders is used in a private house in the absence of a main gas pipeline or other centralized structures. Experts note that the method is suitable for houses with an area of 70-100 m2, which are pre-insulated to reduce fuel consumption.

Note! To save on fuel purchases, it is recommended to install a gas boiler paired with electrical appliances.

You should know that it is strictly forbidden to disassemble gas cylinders. Fuel is pumped into a container under high pressure, passing from a gaseous state to a liquid one. Liquefied hydrocarbon gas is commonly called LPG.

Advantages and disadvantages of balloon heating

The advantages of the system include:

cleanliness of the fuel, the gas burns completely, leaving no ash or slag;
system autonomy - no connection to electricity required;
stability of work;
ease of operation and management;
relatively low fuel costs;
high efficiency;
the ability to convert the boiler to work with a main fuel supply;
long service life.

Such gas cylinders are highly valued on the secondary market and they can always be sold, returning part of the money spent. The system also allows you to supply country house hot water, that is, the heating method is suitable for houses where central communications are not connected at all.

Disadvantages include the need to refuel containers and the need to create certain conditions for the operation of the entire structure. It is worth carefully studying the connection diagram so that in cold weather you are not left without heat due to failures in the system.

Connection diagram of gas cylinders to the heating boiler

Connection to the system is carried out through a special gearbox. The device converts fuel from liquid to gaseous state for supply to the boiler. If there are 2 or more containers, several reducers are used, each of which is connected to one cylinder. This method is considered safer than connecting through one general type gearbox.

Advice! If you connect several cylinders to the boiler at once, you can increase the time between refilling the containers.

The design is formed using a ramp - a two-arm collector that distributes the tanks into two groups, the main and reserve. First, gas is taken into the boiler from the main group of cylinders, then from the reserve one. The switching is automatic, the owner hears only the warning signal from the devices. As soon as the cylinders of the main group are filled and reconnected, the ramp switches back to taking fuel from the cylinders of the main group.

You should pay attention to the installation of fuel containers - no closer than 2 m from the boiler, preferably in a separate non-residential compartment or room. You cannot place containers on open place, accessible to sunlight.

Advice! In order for the gas pipeline to be reliable, the walls of the pipes must be made of metal with a thickness of 2 mm. At the points of passage through the walls, the pipes are protected with a case, and the holes are foamed. The pipeline is connected to the boiler using a durite hose.

Components for balloon heating systems

To arrange gas heating From bottled gas the master will need:

gas boiler with burner;
cylinders (capacity 50 l);
gearboxes;
ramp;
shut-off valves;
durite hose for connection (rubber-fabric sleeve).

The entire circuit is extremely simple to install, so it is easy to implement home handyman. It should be remembered that when choosing a boiler, it is better to give preference to the one with the minimum operating pressure, but the maximum high efficiency.

Note! Manufacturers offer boiler models adapted to work with cylinders. If a main line is not expected in the near future, it is easier to choose just such equipment.

When choosing a heating unit using liquefied gas, it is important to pay attention to the burner; it should be specifically for propane. Burners for use with natural fuel are designed for lower pressure in the system and have an expanded nozzle diameter, which can lead to an accident when supplying fuel from a cylinder.

When purchasing a conventional gas boiler, the master will have to purchase nozzles for the burner, gas valve– these parts are found only in devices designed to work with LPG.

Calculation of gas consumption

To achieve comfortable heat in the house, fuel consumption must be at least 1 kW per 10 m2. Let's consider how much fuel is needed for a house of 100 m2. The boiler must have a power of at least 10 kW; to produce 1 kW of heat, the equipment consumes up to 0.12 kg/hour of fuel. Thus, the consumption per hour for the entire area is 1.2 kg, which is equal to 28.8 kg per day.

The approximate volume of a 50-liter cylinder is 22 kg; it turns out that heating with propane will cost the owner of the house 9 cylinders per week. It's expensive. But there is an amendment: enhanced mode is required only when the system is warming up, then a properly adjusted boiler will require no more than 8 kg of gas per day, that is, consumption is reduced by 3-4 times.

To maintain comfortable heat in a 100 m2 house, which is well insulated, the entire system is adjusted and equipped automatic switches, 3 cylinders of gas are enough for a week. At the same time, the temperature in the rooms inside the building will be maintained at +22 C, provided that outside it is down to -20 C.

Important! If you automatically configure the system so that at night the temperature in the house is maintained no higher than +18 C, that is, it decreases in relation to the daytime by 4-6 degrees (more is possible), you can reduce fuel consumption by up to 30% per week, and this is only 2 cylinders.

Automatic adjustment allows you to reduce the temperature when there are no people in the room. For example, at the dacha in winter period A thermometer reading of +5 C is enough to keep the heating system in working order. In this case, one bottle lasts for 7-10 days.

Safety precautions when working with gas cylinders

Propane heating requires strict safety precautions. In addition to the fact that you should not place the cylinders closer than 2 meters from the boiler, avoid direct rays and overheating. Still unacceptable:

In case of freezing, use an open flame to warm the cylinders. In general, fire and gas containers are an explosive combination, so if an accidental fire occurs, the fuel container should be removed first.
When arranging a room for cylinders, it is necessary to ensure that there is no cellar or basement next to the room. The gas is odorless but has physical property go down. Thus, a person who goes down into the cellar may become poisoned. Also, if there is an unnoticed gas leak, large accumulations of fuel in the cellar will lead to an explosion.
To minimize the risk of fire, a gas leak meter must be installed in the system.
Storing empty cylinders in the house is strictly prohibited. A warehouse with full containers should be located no closer than 10 meters from a residential building.

Important! Preventive maintenance and inspection of the system and the integrity of the cylinders must be carried out at least once every 4 years.

Features of cylinder operation in winter

Using liquefied gas to heat a house is a good option for country houses. The safety requirements are reasonable, the system can be equipped independently, but it is important to take care of keeping the fuel in working order during the winter.

When the cylinders are located outside the building, with negative temperatures the pressure decreases and the boiler may stop working. In order not to be left without heat, during the winter fuel containers should be placed in a closet with an equipped ventilation system and protection from non-flammable insulation. As a last resort, an extension without heating, where the cylinders are placed, is suitable.

City residents are actively constructing dachas and country houses, developing territories nearby the populated area. Areas near which there is no gas pipeline are no exception. In the absence of supply lines and a centralized supply of hot water, property owners decide to connect gas boilers for heating from a cylinder. The use of liquefied gas makes it possible to heat houses and heat water. Let's look at the connection features and evaluate the advantages and disadvantages of balloon heating.

Is it possible to connect gas boilers for heating from a cylinder?

When wondering whether it is permissible to use a gas boiler for heating from a cylinder, you need to know that the design features of most heating units provide the ability to operate on various types of gas:

main, which is supplied through centralized gas supply lines;
bottled propane, which can be pumped into containers of various sizes.

Due to the fact that in the delivery state the main part of the heating units is designed to operate on main fuel, it is necessary to perform one of the types of work related to conversion:

replace injectors;
dismantle the burner.

After the conversion, all types of heating devices will be able to operate on liquefied fuel, regardless of their heating capacity and combustion chamber design:

single-circuit and double-circuit;
wall-mounted and floor-mounted.

When choosing a gas boiler for heating from a gas cylinder, pay attention to the following points:

the feasibility of using units with reduced operating pressure, which will allow the use of liquefied bottled gas with the maximum degree of efficiency;
the use of devices with increased efficiency, ensuring efficient combustion of fuel at minimal cost.

Having answered the question in the affirmative about the possibility of connecting heating devices to tanks, we will dwell on them in more detail.

Bottled gas is the main power source

Metal containers intended for storing liquefied gas under pressure differ from other types of containers:

volume, which is 5, 12, 27 and 40 liters;
degree of filling, which should not exceed 85%;
design of the adapter fitting;
red, indicating explosive hazard.

Refueling possible various types gas:

propane;
butane;
a mixture of propane and butane.

When heating a dacha with gas cylinders, the latter option is used.

The gaseous fuel, which occupies an increased volume, is liquefied in a special way. When compression is carried out, the gaseous fraction becomes liquid, which makes it possible to fill the container with a gaseous substance in an increased volume. In order to prevent a fire hazard, it is prohibited to connect cylinders directly to consumers without using a special reducer.

To power the boiler with liquefied propane, you need to prepare:

a reducer designed to reduce pressure;
shut-off valves that allow you to shut off supply lines;
pipes connecting individual elements into a common system.

When using bottled gas, you must pay special attention to compliance with the rules fire safety.

The main advantages of bottled gas:

environmental cleanliness;
autonomy;
ease of use;
constant pressure.

The main disadvantages of using household containers:

insufficient volume;
the need for periodic refueling.

Connecting a group of tanks with a common network will allow you to reduce the number of trips to update tanks. Let's look at this point in more detail.

Features of connecting reserve cylinders

During the operation of a gas heating system, situations arise when the gas supply is interrupted at night and heating stops. This causes a lot of inconvenience for residents, since it is necessary to regularly monitor the filling of containers.

It is possible to perform a group connection of a heating device using a special ramp. Design features ramps allow you to combine up to ten backup power tanks. Operating principle of the ramp:

containers are divided into separate groups, each of which is equipped with its own pressure regulator;
the working group of cylinders supplies gas to the main line that supplies the heating unit;
switching work to backup power carried out automatically after the end of gas in the main tanks with automatic signal generation;
automatic switching to operation from the main group is carried out after full refueling.

Using a group arrangement allows you to increase the time interval between refills. Possible various options connections:

a common reduction gearbox, which is mounted on the output line;
an individual device installed on each container.

Despite the increased costs, the second option is safer.

How to heat a gas boiler using a propane cylinder

It is important to correctly connect the heating system to the tank, while ensuring that safety requirements are met. It is necessary to use a gearbox that matches the performance:

a device designed for gas flow up to 2 m3/hour can be used to supply liquefied gas;
A gearbox with a capacity of up to 1 m3/hour, intended for stoves, cannot be used for heating.

Please note the following points:

availability of free access to containers with liquefied gas for maintenance;
inadmissibility of gasification of premises located in the basement or basement of the building;
maintaining the distance from the tank to the boiler or stove, which should be more than 100 cm;
the maximum volume of tanks, which for residential premises should not exceed 55 liters;
vertical arrangement of containers that are prohibited from being used in an inclined position or lying down;
the metal box with tanks must be closed and located in a safe place;
diameter of corrugated hoses or copper tubes, which, with a size of more than 2 cm, will ensure gas supply at maximum unit performance;
the use of a purchased unit for connecting tanks, equipped with a pressure gauge, will allow you to control the pressure and check the presence of gas.

Carrying out connection activities heating system should be entrusted to professionals who have undergone special training and are licensed to perform explosive work.

Is it allowed to install refilled cylinders in the boiler room?

Current regulatory documents on fire safety regulate the rules for installing liquefied gas tanks. Regulations prohibit placing them in a common room with boilers.

Main requirements:

it is allowed to install tanks in a nearby room or outside the building in a special metal box;
Empty containers should be stored outdoors, but it is better to refill containers on time;
to prevent freezing of containers installed in a metal box, it is necessary to use thermal insulation materials, not subject to combustion;
heating containers with frozen gas using an open flame is prohibited;
storage of supplies is permitted only in a ventilated room without pits;
It is necessary to monitor the tightness of tanks at intervals of four years during the certification process.

Remember that compared to air, propane is a heavier gas, which, if leaked, concentrates in basements and pits. When a critical concentration is reached, an explosive situation is possible.

Is it necessary to reconfigure a gas boiler for heating from a gas cylinder?

There is no need to reconfigure the heating device if it is correctly converted and connected in compliance with all requirements. Prerequisites functioning:

installation of additional elements designed to maintain constant gas pressure;
possibility of stable work heating unit when gas pressure drops to 4 mbar.

You should read in detail technical description and the boiler operating manual, which indicates the possibility of operating on liquefied fuel and regulates the operating pressure.

How to provide gas heating for a dacha using cylinders

The process of switching the boiler to liquefied fuel involves performing the following operations:

installation gas burner and dismantling the metering nozzles. This will ensure the boiler operates at a reduced pressure that corresponds to the cylinder pressure;
installation of a reduction gearbox. The device allows you to reduce the output pressure of a substance when it transitions to a gaseous state;
checking the functionality of the gas valve. A number of heating devices need to replace the specified unit when switching to bottled gas.

Switching work is carried out only by representatives of specialized organizations.

Method for calculating the volume and need for cylinders for a boiler

the amount of gas contained in one tank allows heating a room of 50 square meters for a week. m;
The average consumption of “blue fuel” by the boiler, spent on generating 1 kW of heat, is 120 grams per hour.

Once you have specified the area of the heated room, you can easily perform a simple calculation. For example, for a house with an area of 150 sq. m weekly you will need 3 propane tanks of 40 liters each. Multiplying the resulting value by 4 weeks, we get the monthly requirement - 12 pieces. For uninterrupted operation, you can simultaneously connect 6-8 tanks in two groups of 3-4 each.

Equipping the heating system with automatic elements will reduce gas consumption by regulating the temperature at night. For periodic stays, for example, only on weekends, a significantly smaller amount of fuel will be required, which will significantly reduce its consumption.

Heating with a gas boiler from a cylinder - pros and cons

The main advantages of an autonomous heating system connected to cylinder tanks:

accelerated and simplified connection;
no need to obtain a launch permit;
possibility of installation without design documentation;
independence from centralized systems fuel supply.

Along with the positive aspects, there are certain disadvantages:

the need to use a ramp to connect to the system;
the need for regular monitoring of the availability of “blue fuel”;
increased costs of maintaining a comfortable temperature;
additional costs for boiler conversion;
hiring specialists to connect the tanks into a network and replace the burner.

Despite a number of disadvantages, gas heating of a dacha with cylinders is alternative option in the absence of a centralized gas supply.

Conclusions

Individual heating systems powered by liquefied fuel allow you to maintain a comfortable temperature at any time of the year. When deciding to switch to bottled gas, it is necessary to carefully analyze the pros and cons of the specified heating system. Using the services of specialists, you can safely connect and quickly put the equipment into operation.

Nowadays, energy sources such as electricity, gas and solid fuels are becoming popular. Some users try to combine options and heat private house using gas, and, for example, solid fuel boiler. A controversial question arises: does this method really save money? Not always. One of the most profitable options for heating a home (if it is impossible to connect to the main gas pipeline) is to use gas cylinders. Of course this method, in addition to the advantages, there are also disadvantages, which every owner of a private house planning to know about this type heating.

Basic elements of gas cylinder heating

For a gas heating system, the home owner must purchase the following:

A boiler that runs on both main and liquefied gas. Of course, if you have extra funds, you can buy 2 boilers, each of which will be adapted for a specific type of gas. But, as it turned out from user reviews, such a solution will only lead to unnecessary waste of money. You should know that before connecting another type of gas, the boiler jets or the entire burner should be replaced. In more modern devices, it is also necessary to reconfigure the automation and control system (see video below).

Shut-off valves. Allows you to shut off the gas flow in emergency situations or when necessary, for example, during repairs. A common element of any gas main is a standard valve.

Automation and control system. There is no particular need to install this system, but automation eliminates human intervention. Also, such systems are very often equipped additional elements protection.

Important! Bottled gas is heavier than air and, if leaked, will accumulate in the lower part of the room. For this reason, a ventilation system must be provided that will work effectively throughout the entire volume of the boiler room. Contact the services of qualified specialists!

Gas reducer is a device for reducing the pressure of a gas or gas mixture at the outlet of a container (for example, in a cylinder or gas pipeline) to operating pressure and for automatically maintaining this pressure constant, regardless of changes in gas pressure in the cylinder or gas pipeline. Proper functioning of the system without a gearbox is impossible.

If possible, use gas cylinder units, one of the manufacturers of which is the German company GOK.

All of the above elements of the gas cylinder system have different pricing policy. It all depends on the owner of the house, but it should be remembered that the use of low-quality and cheap gas cylinders can lead to very bad consequences.

A little theory

Before you install gas equipment in the house, you should find out its operating principle, as well as familiarize yourself with the structure of the entire system.

Propane-butane is pumped into the cylinders.

Propane-butane- universal synthetic gas obtained from associated petroleum gas or during oil refining, i.e. in fact, for most manufacturers it is a by-product.

In order for gas to be transported and used in cylinders, it must be converted from a gaseous to a liquid state. Therefore, before filling the tank, the gas is diluted, this allows it to be pumped in larger quantities.

Lukoil cylinders in warehouse ready for shipment

After connecting the cylinder to the main line and opening the tap, the gearbox starts working. The reducer reduces the pressure several tens of times, because of this the gas returns to its original state and can be used as fuel for heating rooms. The reducer allows you to use the entire capacity of the cylinder.

It should be remembered that any gas cylinder has high blood pressure inside and therefore requires appropriate handling and maintenance.

The main advantages of heating a house with gas cylinders

This system is most often used for heating small area– up to 100 m². Ideal for country houses, cottages, as well as small private houses.

The main reasons why people choose gas heating:

The cylinder heating system has a higher efficiency than solid fuel or electric boilers. According to average indicators, from 6 to eight cylinders per month are enough to heat an area of 100 m².
To re-equip the system, you do not need to purchase a special boiler; it is enough to install new nozzles on the old one. In the same way, the system can be returned to its original state.
When installing cylinders, the heating system becomes autonomous - the owner of the house becomes independent from breakdowns and maintenance of the central line.
When purchasing high-quality gas equipment, the user can rest assured of its durability. For a long service life of this system, it is only necessary to carry out maintenance on time, for which time is usually allocated before the heating season.
High demand for heating systems with cylinders. This means that, if necessary, the system can be quickly sold, either as a complete unit or separately.

Of course, no system can be perfect. Disadvantages exist in any design: high consumption fuel, insufficient level Efficiency, high cost of maintenance and repair. In gas-cylinder systems, these are additional costs for refueling and transporting containers (cylinders). The installation of the system and the purchase of the following elements are also high: boiler, gas cylinder installation, cylinders.

Selection and operation of a gas boiler

As mentioned above, there is no need to look for a “special” heating boiler running on liquefied gas - modern products can run on both natural gas and liquefied gas. Accordingly, when choosing a boiler, you should proceed from the total area of the heated room. You can install a convection or condensing boiler. The convection device is mounted on the wall and can cope with an area of up to 300 m². Condensing boilers are not only more powerful (heated area is at least 400 m²), they are also more economical.

The topic should be addressed separately hot water. Many users specifically install an electric boiler, believing that this way great savings can be achieved - this approach is incorrect. It would be correct to purchase a double-circuit gas boiler. Gas consumption does not increase much, but the quality of hot water changes dramatically.

Popular models of double-circuit boilers include Buderus Logamax U072-24K - designed to operate on both natural and liquefied gas.

In order for the boiler to function properly, maintenance should be carried out correctly and in a timely manner, which includes:

Replacing the coolant in the heating system (at least once every 5 years) if non-freezing liquids of the “type” are used Warm home"etc. When using water as a coolant, replacement is not required.
Cleaning the internal parts of the boiler from carbon deposits.
Replacement (if necessary) of rubber components - rings, gaskets, bushings, etc.

Setting up the boiler for liquefied gas

The pressure of the gas coming from the cylinders is much higher than the natural pressure. For this reason, the purchased boiler must be reconfigured. As a rule, the procedure is limited to two steps:

Installation of jets with holes of smaller diameter (or replacement of the entire burner).
Setting the gas pressure according to the passport data.

Important! No matter how simple it may seem to set up a boiler for liquefied gas, it must be done by specialists.

The video below shows the setup process for the most popular models.

Correct use of gas cylinders

Tanks for storing and transporting liquefied gas must undergo annual verification if they are in constant use, unless heating season– 1 time every 2 years.

Cylinders cannot be installed in either basements or basements. Where the cylinder will be installed, a solid floor must be installed, without cavities or free space. This requirement is due to the fact that the gas is heavier than air, and if the system is not tightly sealed, its accumulation leads to the possibility of an explosion. If there are no other rooms, then the basement should be properly equipped: install a concrete floor, and also eliminate free space in the walls, if any.

Containers should not be used in an inclined position or lying down. Only vertically, having previously secured it to the wall using a special clamp. The clamp prevents the container from accidentally falling. To ensure that the cylinder can be checked or quickly replaced, it should be installed separately from the main equipment. Near the product in use, for better practicality, you can mount mounts for spare containers.

More details about cylinder cabinets are described in the video below.

Gas cylinder equipment in cars and private homes is identical, and when operating it, you should be guided by the basic rule - do not fill the cylinder completely. Products that are more than 90% filled have a sharply reduced service life and an increased risk of explosion.

Gas cylinders should not be left in direct sunlight - gradual heating of the outer surface of the product can also lead to an explosion.

When using a heating system in your home based on the use of gas cylinders, you must not forget about periodic maintenance. Typically, users try to do maintenance before the heating season, or immediately after it ends.

How to calculate a heating system using gas cylinders

To understand the practicality and cost-effectiveness of this heating system, you should carry out preliminary calculations and answer an important question: for what period of time is one cylinder enough?

The sequence of calculations based on average statistical readings:

The boiler power must correspond to 1 kW of energy per 10 m2 of room. For a private house with a total area of up to 100 m2, it is necessary to purchase a gas boiler with a capacity of at least 10 kW. Installing heating radiators, instead of ordinary multi-section radiators, will facilitate faster heat transfer throughout the entire area of the house.
For the gas boiler described above, at least 0.86 kg/h of liquefied gas will be required, taking into account the fact that the boiler efficiency must be at least 90%.
The heating season usually takes no more than 6 months, sometimes 7 (if April is too cold). 7 months – 5040 hours. Of course, the boiler will not work at the same power all this time; for greater efficiency, you should alternate operating modes.
1 cylinder with a capacity of 50 liters holds 21.2 kg of liquefied gas. The calculation is made: 5040 is multiplied by 0.86 kg/h and the resulting value is divided by 21.2 kg of gas. The final value (rounded down) is 204 cylinders for the entire heating season. This figure will be even greater if, instead of cylinders with a capacity of 50 liters, you use products with a capacity of 27 liters.

Such calculations are very superficial, because no user will constantly keep a gas boiler at full power. But, based on these values, which should also be multiplied by the price of gas (add transportation and refilling of cylinders), you can decide whether it is worth installing a gas-cylinder heating system.

How long does one gas cylinder last?

When alternating temperature conditions, one cylinder is enough for 1-2 days. IN given value also includes the use of hot water. At this flow rate, the temperature in a house with an area of up to 100 m2 will be from 21 0 C to 23 0 C. An important factor here is the weather outside. For example, at -15 0 C, up to 4 cylinders can be used per week, and when the temperature drops to -25 0 C, a gas boiler of insufficient power may simply fail.

Is it possible to reduce gas consumption

This is not only possible, but necessary. Since several simple elements in the gas cylinder system help to significantly reduce gas consumption.

Install special sensors that indicate the presence of gas in the room. This allows you to timely identify a leak (which leads not only to an explosion, but also to excessive overspending) and eliminate it.
Without fail, gas system heating should be automated. Only with the use of automation elements can lower fuel consumption be achieved.
Use only high-quality and real fuel, without additives. If there are impurities in the gas, its consumption increases significantly.
Monitor the temperature in the room in which gas equipment is installed. It, like the rest of the rooms, should be heated. Insufficient temperature in the combustion chamber may cause a gas boiler to fail.

In addition to the above measures, the outside of the house should be insulated. High-quality insulation will help achieve minimal gas consumption and a more comfortable temperature in the house.

Costs and reviews

There are many videos on YouTube in which residents of the former Soviet Union share their experience of heating with gas cylinders. The video also includes real gas costs.

An autonomous heating system is both an opportunity to save money and the ability to independently set the room temperature at any time of the year. But there are situations when frosts can strike in mid-May (and central heating disconnected already in April) is not uncommon for us lately.

It’s at moments like these that you realize: independent heating– this is a necessity. The only question that arises is: what type of boiler to choose? The answer suggests itself - gas. It is no secret that this resource is the cheapest and most cost-effective in comparison with others. But what to do when your house cannot be connected to the gas mains. There is a way out - you can use bottled gas boilers. We will talk about them further.

Advantages and disadvantages of bottled gas boilers

Among the main advantages of gas boilers, the following are worth highlighting:

low cost of gas itself;
high efficiency (due to not high content in gas of sulfur compounds);
easy operation;
large range of boilers different models and manufacturers.

In addition, during combustion, gas emits very few harmful substances that can harm human health. Such boilers work properly for much longer, due to the fact that they are less susceptible to corrosion than other types.

Among the disadvantages is the need to build a chimney through which combustion products will be discharged. Also, for installation in an apartment building you will need to obtain permission. Although in most cases electric boilers are not allowed to be installed in such houses at all, since the electrical network may simply not withstand such a load.

When should bottled gas boilers be used?

Another disadvantage of gas boilers is the mandatory presence of a main gas network. But as we mentioned above, this problem can be solved - you can use gas cylinders. In this case, there is no need to install additional spare parts: gas boilers are usually designed for both main and bottled gas supply. Unfortunately, bottled gas boilers cannot be used for constant heating of a room. This is rather a temporary solution until the gas pipeline is installed. Let's figure out why.

In order to heat a room with an area of one hundred square meters You will need to use about two cylinders of gas per week. Simple calculations will show that up to 9 cylinders will be needed per month to heat such a house. A total cost their refueling will exceed the cost of main gas, if only because of transportation costs. However, using even bottled gas will be cheaper than operating an electric boiler.

The inconvenience lies in the need to constantly replace cylinders. Of course, many of these boilers provide for the use of a group at once (up to four cylinders), but even these will have to be changed over time and sent for refueling.

The use of boilers running on bottled gas can be a good solution permanent source heating only for a country house, which you rarely visit in winter. If there is no gas main in that area and the house will only be heated for a few weeks in winter, then don’t even think twice about it - install a boiler with cylinders.

Features of connecting and choosing bottled gas boilers.

Considering that a gas boiler using bottled gas and a boiler using main gas are the same type of boilers, the rules for installing and selecting this heating element are different sources gases are the same.

Boiler selection

When buying a gas boiler, consider the following parameters:

number of circuits: there are single-circuit boilers designed exclusively for heating, and double-circuit boilers that can also heat water;
installation type: floor or wall;
combustion chamber type: open or closed;
boiler power.

It is worth considering that when choosing a boiler that will operate on bottled gas even for a short time, you need to pay attention to the operating pressure. You will need a boiler that can perform its functions even at low pressure (3-4 mbar). The efficiency indicator is also taken into account, especially when using cylinders. It is best to choose boilers with high efficiency - about 90-95%.

Features of installing gas boilers

The boiler must be installed taking into account the following requirements:

the boiler is installed in a room with a ceiling height of at least 2.3 meters;
the boiler should be placed from the wall at a distance of 50 centimeters;
the boiler can be installed in rooms larger than 8 sq.m.;
in the room where the boiler will be installed, there must be a window for ventilation and a door, access to which is always free.

At making the right choice, proper installation and careful operation of a boiler running on bottled or main gas, you will receive a cost-effective and non-toxic source of heating. This means that your home will always be cozy and comfortable, regardless of the weather outside.

Those who own private houses or summer cottages are one way or another faced with the question of how to maintain a comfortable temperature in it even in the most severe frosty winters. The variety of types of heating is quite large, but one of the most common is gas heating with cylinders. Why it is so widespread and how they can provide for their home should be understood in more detail.

Prices for gas cylinders

Gas equipment for heating a cottage

When the question arises about heating with gas cylinders, it is best to contact specialists about this, so the likelihood of error will be reduced to zero. But this does not mean that you do not need to know thoroughly the process of heating with gas cylinders. In order to install this type of heating into a house, a certain combination of devices is needed:

Using a gas boiler, gas fuel is converted into heat energy.
In order for the boiler to function, it is necessary to install a burner that ignites the liquefied gas in the boiler.
Directly a gas cylinder as a source of fuel.
The reducer connects the cylinder and the boiler.
Pipes are necessary so that the entire system is interconnected and can work holistically.

Can be used for heating a home various types cylinders, which have their own positive and negative characteristics, taking into account which a choice should be made. They are:

Cylinders made of metal or steel.
Polymer-composite.
Metal-composite.

Metal cylinders

This type of cylinders became popular a long time ago for a simple reason - previously there were only cylinders of this type.

However, time-tested, they have a fairly large number of disadvantages, which are not known to everyone, because they continue to be used to this day:

The first disadvantage of this type of gas tank is its heavy weight. When empty, it ranges from 4 to 30 kilograms.
The lack of transparency is not a very convenient characteristic for a device in which it is desirable to see the amount of content remaining there. With a design made of opaque material, it is not possible to control the filling level of the cylinder.
Lack of a sufficient level of safety due to the fact that there is no equipment with the necessary protection if such a tank is affected by improper operation. There is a high probability that it may explode, scattering into many small fragments.
It is not resistant to corrosion processes, because it is made of metal. The possibility of being exposed to water, which causes corrosion, is great during transportation, storage and during use. In addition, there is water in the form of steam in the inside of the tank, which is also dangerous due to the occurrence of a corrosion process.
The material is not strong enough to be impact resistant. Even though the metal itself is strong, due to long-term operation may be damaged in various ways. As a result, it may turn out that another blow will lead to cracking of the cylinder shell, which promises unpleasant consequences.
During transportation, cylinders often come into contact with each other, and this is dangerous due to the possibility of spark formation. What will a spark in combination with gas lead to?
There is no supply of a bypass valve, which serves as insurance in the event of an overinflated tank, or an incorrect filling process, or heating of the surface of the cylinder.

Polymer composite cylinders

This type of gas container was invented recently. They are produced using fiberglass thread. They have a mass that is 40% less than those made of metal. They are quite convenient for storage and require little space. The advantages can be listed:

Providing the housing with impact-resistant properties and explosion protection. This is due to the fact that the cylinder is braided with a special casing, which in the event of an explosion will compensate for the force of the impact. In case of an emergency, only this casing will have to be replaced.
There is no possibility of sparks forming during contact, which also plays a role regarding the explosion.
The gas containers are made in such a way that if they are near an open flame or in conditions of temperature exceeding 100 degrees, they do not succumb to explosion.
In addition, such cylinders are transparent, which makes it easy to observe the amount of fuel in it.
It is not subject to corrosion due to its composition. This ensures good visibility and maintains the integrity of the material.

Important: the cylinder can operate in a temperature range between -40 and +60.

The cylinders are equipped with a bypass valve, which eliminates excess pressure in the event of overheating of the cylinder and pumping its contents. These parameters exist due to the presence of a fusible link, which, if necessary, will melt and give space for excess gas to escape into the environment.

Metal-composite cylinders

A type of gas container that is intermediate between the two previous options. All the parameters that the cylinder has are at an average level, such as weight and safety. There is internal corrosion in it, since it is equipped with a metal liner inside. The material is not transparent; the design provides for various monograms.

Choosing a boiler for heating a dacha with gas cylinders

When choosing a boiler for a heating system using a gas cylinder, you need to pay attention to the following number of parameters:

The amount of fuel consumed per hour. This parameter depends on how much area needs to be heated.
Pressure level. Gas consumption depends on pressure; the lower this indicator is, the lower the consumption will be.
Automatic equipment. Some boiler models have the ability to switch the heating power and set the required level.

Also important parameter is the efficiency, which should be close to 100%. The type of burner that will be installed in the system depends on this:

Inflatable.
Atmospheric.

The first type of burner is characterized by the fact that the gas is burned to its fullest extent, which ensures the highest degree of efficiency. Plus, equipping with automatic heating level switching systems can save 20% of gas. Some models of this type are produced without a chimney, which significantly saves material investments in assembly and purchase of additional equipment.

When choosing heating equipment, you should carefully consider the choice of the cylinder itself, if the type for choosing one is metal. This type of container must have a special inscription indicating the date on which the fuel was filled and the number of the cylinder itself. The color of gas containers should be red or orange.

Important: it is not recommended to use cylinders without the characteristics listed above.

What you should know before installing a gas cylinder in your dacha

One of the main elements in a gas heating system is the reducer. It is needed for the reason that the degree of pressure in the cylinders is often an unstable value; it may depend on the volume of remaining fuel, what composition the mixture has, or the distance from the consumer. In this regard, you need a device that can produce a constant level of pressure, regardless of the factors that interfere with this.

You can select a gearbox according to the parameters indicated on its body:

Performance. To calculate what performance gearbox to buy, you need to start from the fuel consumption per unit of time. The ratio should be such that this gearbox parameter is greater than or equal to the boiler intake capacity. Gearboxes with minimum parameters performance cannot be installed in the house for heating.
Working pressure level. There are reducer models that allow you to adjust the pressure level in the range of 20-60 mbar. If you purchase another type of device, you need to pay attention to ensure that the indicators of the heating devices and the gearbox are equal. Standard models assume a working pressure of 30 to 50 mbar.

If necessary, connect the system using flexible hoses, you need a gearbox equipped with a herringbone fitting. When installing rigid pipes, it is necessary to purchase a device that has threaded outlets.

Principles of installing a heating system

There are several options for connecting the entire heating system with gas cylinders in the house:

First option involves connection using curved pipes made of metal, manifolds and plastic hoses with reinforcement. The connection diagram in this option is linear, in which all gas containers are combined into one flow and they operate synchronously.
Second option is a system of cylinders that switches between each other. This is done using a gearbox with the ability to carry out such switching automatically or manually. The connection diagram looks like this: some of the cylinders are connected and in operation, and some are a reserve stock. In the event that the gas in the main part of the fuel tanks runs out, it switches to another. This allows you to save time when you need to fill the cylinders, because turning off the fuel supply to the system is not required. Another advantage is that gearboxes of this type have special valves that regulate the pressure level when it increases due to various external influences.

How to install a gas cylinder for heating a summer house

Rules should be followed when installing gas cylinders for heating, which will ensure the correctness of the process and safety:

The installation position of the gas container should only be vertical;
it must be installed in a place to which there is access so that, if necessary, the equipment can be inspected or replaced;
the distance from heating devices must be at least 1 meter;

Important: installing gas heating in basements or basement-type rooms is strictly prohibited.

It is important to remember that even if you are confident in your abilities and knowledge of how to install gas cylinders for heating, it is forbidden to do this yourself; you need to use the services of specialists, as in the case of repairing or replacing equipment. The sequence of actions during installation by the wizard is as follows:

The room (dacha, house) in which the gas cylinder will be installed must be well ventilated.
First, in an open space, the container with fuel is checked for leaks. This is checked by soaping the monograms and fitting holes. If soap bubbles appear, the use of such a cylinder is prohibited.
The next thing to be checked is the integrity of the rod seals and connections in the uncorked state and in the closed state of the valves after the connection. The check is carried out in the same way soap solution according to a similar principle. If bubbles are detected, you should call the emergency service and take the cylinder out into the open air.
After checking the tightness of all devices, you can connect the entire system together using pipes and a gearbox. The scheme according to which the installation is carried out is selected in advance and the pipeline is laid according to the scheme.

Important: the pipe material must be steel, the pipe type must be bellows. The use of other types of pipes for gas heating is prohibited.

Storage and safety rules

The first thing you need to pay attention to is the amount of fuel that is allowed to be stored:

ten-liter containers in residential premises, provided that the container is sealed;
three-liter containers that have characteristics that are resistant to fire and shock.

Rules to follow when sending cylinders for storage:

when choosing a place to store gas containers on outdoors, you need to make sure that there is no direct sunlight in this place;
Only containers that have been checked for integrity are allowed to be stored;
if corrosion processes are detected on the surface of the cylinder, it is strictly prohibited to send it for storage;
the residue pressure level must be below 0.05 MPa;
the temperature regime for storage must be maintained within 45 degrees;
When storing, keep the distance between fuel containers more than half a meter from each other and from heating devices.

Advantages and Disadvantages

The gas cylinder heating system has many positive characteristics:

are economical;
do not require additional devices for normal operation;
easy to install and replace;
no need for electricity consumption;
With this type of heating, oxygen is not burned.

However, there are several negative aspects to using gas equipment:

there is a possibility that the heating system will turn off if gas cylinders freeze on frosty days;
choosing a room for installing cylinders is quite difficult, since their installation in rooms with poor ventilation is prohibited;
gas has a higher density than air and if the system is not tight, it will fall into the lower parts of the building and, accumulating there, can cause unpleasant consequences.

Conclusion

The heating system, which uses cylinders, is quite simple and convenient, and also saves a good amount of money both during installation and during the period of operation. If you carefully approach all installation processes and equipment selection, you can eliminate all the disadvantages of this heating system.
