Radiators and their varieties

To ensure that your home is always warm and cozy, you need to be extremely responsible when choosing batteries. Let's talk about the types of heating radiators, the advantageous characteristics of each type, their technical features and shortcomings.

On the market today heating devices a huge variety of different modifications are presented. Therefore, the consumer is often lost in the assortment and does not know which radiator to choose. It will help answer this question benchmarking the most common options.

Existing varieties based on material of execution

There really is plenty to choose from - on the shelves specialty stores Batteries of different shapes and sizes are displayed. But almost all of them are made of four main materials. Therefore, experts distinguish four main types of radiators:

• Cast iron.
• Aluminum.
• Steel.
• Bimetallic.

Pay attention! Each has its own scope of application, its own advantages and disadvantages. By comparing them, you can form a correct idea about the heating device.

Therefore, let’s take a closer look at each one separately.

Cast iron batteries - main technical characteristics

The domestic central heating system was initially focused on the use of cast iron radiators. And the devices have stood the test of time with dignity. Even today they are considered optimal, but the appearance of such batteries does not meet the requirements of modern decor.

Cast iron radiators can operate for decades without requiring special costs for repairs. And all because cast iron is resistant to impurities contained in the coolant. They are used to maintain its temperature, as well as to maintain the throughput capabilities of heating mains.

Special technical characteristics

Modern manufacturers still produce cast iron batteries. At the same time, new heating devices have become more elegant, and even interesting decorative masterpieces made in retro style have appeared.

However, when buying radiators, experts recommend not chasing beauty, but paying attention to the technical parameters of the devices:

• Firstly, these are heat transfer rates, the weight of one section and the atmospheric pressure that each battery can withstand.
• Secondly, the power of the unit, its width, height, depth of the ribs, as well as the advantages of the material from which the sections are made are of no less importance.

Positive aspects of use

Cast iron radiators have a lot of advantages:

1. The material has high corrosion resistance, which is due to interesting property metal During operation, the surface of the product becomes covered with dry rust, which prevents further spread of the process. High anti-corrosion resistance allows the use of cast iron batteries in systems where steam with a temperature of more than 150 degrees is used as a coolant.
2. The durability of cast iron batteries is ensured by their thick walls. It will take a long time for cast iron to rust through, so this type radiators are considered the most reliable. For the same reason, they can be used in open systems and where the coolant is completely drained to summer time. For comparison, steel is afraid of oxygen, so products made from it must always be filled with water. Otherwise, they will not last even two seasons; they will quickly rust from the inside and leak.
3. Cast iron is not afraid of low-quality coolant. It does not react to an alkaline environment whose pH exceeds 9.5 units. Small pebbles, salt impurities, and rust coming into the batteries from the main line do not cause dangerous damage. Cast iron is difficult to scratch or dissolve because its abrasive resource is inexhaustible. The only weak point is the seals at the joints of the sectional parts.
4. High thermal inertia and excellent storage properties also distinguish the products from analogue products. Even when the coolant supply is stopped, the batteries continue to heat the room, gradually releasing heat and slowly cooling down.

Negative points

Types of water heating radiators

However, cast iron radiators also have plenty of disadvantages:

1. The product is heavy, which makes it difficult to transport and install the heating device.
2. A large volume of coolant, which aggravates the first circumstance. To completely fill the cast iron sections, a decent amount of water is required, which further burdens the heating device. And this requires the installation of additional fasteners.
3. The narrower the radiator, the less efficient it is, and the wider and taller the model, the more ridiculous it looks from the point of view of modern decor.

By weighing the pros and cons, you can make the right choice.

Aluminum radiators

Aluminum batteries have recently appeared on the market. New products immediately attracted the attention of consumers, and for a long time only they competed with their cast iron counterparts. However, the joy was short-lived. It turned out that aluminum devices have a lot of technical characteristics that set strict restrictions on their use. Let's look at them in more detail.

Beautiful appearance, light weight, high heat dissipation - one could only dream of such technical characteristics. But practice has shown that aluminum batteries cannot be used everywhere.

Manufacturers offered customers two types of heating devices:

1. Cast construction, where each section is a single piece.
2. Extrusion units in which a section consists of elements glued together.

It is better to purchase cast products, since extrusion ones have a weak point - it is located where the columns connect to the core. Both of them can withstand high atmospheric pressure of 16 atmospheres. In this case, the safety margin is up to 40 atmospheres.

Pros and cons of aluminum radiators

Advantages of aluminum heating devices

The advantages of aluminum heating devices include the following:

1. Aluminum models have high power. The more sections the battery includes, the larger area it can heat. The air heats up very quickly, while a smaller volume of coolant is used.
2. Aluminum radiators are much lighter than their cast iron counterparts, but at the same time they look very elegant, elegant and modern.
3. The described heating devices fit perfectly into modern stylistic concepts.

And everything would be fine, but you can’t use aluminum batteries everywhere. Aluminum is a fragile material that is afraid of an alkaline environment. Alkali literally corrodes parts, turning their surface into a porous sponge that can break at any moment.

Pay attention! That is why it is necessary to carefully monitor the quality of the coolant - its pH should be within 7-8 units. But even this indicator does not correspond drinking water, which is served to Russian residents.

Any impurities very quickly clog an aluminum battery, so install it in the system central heating it is forbidden. It should not be connected to pipes made of other materials, as this will accelerate corrosion processes.

You are not allowed to install the devices yourself. After all, there are a lot of nuances that require mandatory compliance during installation. And if you are not a professional, you can make gross mistakes that will lead to incorrect operation of the batteries and their rapid breakdown.

Steel models

Manufacturers continue to experiment and use other materials to make radiators. Therefore, steel batteries were born, which could not become a universal alternative to the two options described above.

Radiator heating Aqua-Pex

Steel is stronger than aluminum, but it is afraid of oxygen and corrodes much faster than cast iron, but its heat transfer is much higher. These models are not suitable for unstable heating systems, as they are very sensitive to water hammer and do not tolerate coolant drainage well.

Therefore, it is impossible to use steel batteries in apartment buildings and in rooms heated using a central system. But owners of private houses installing autonomous heating systems can take a closer look at this option.

Appearance steel radiators does not cause any complaints. Moreover, you can find various modifications of devices on sale, choose tubular or panel products presented in a wide range of colors.

Bimetallic products

Bimetallic batteries are a new generation of heating devices. They are made of two materials, so they incorporate the advantages of steel and aluminum devices. Manufacturers thereby wanted to compensate for their shortcomings. Therefore, the cores are made of durable steel, and the casings are made of aluminum.

What does this give? Aluminum in this combination becomes less sensitive to water hammer, while steel makes it easier to relate to the quality of the coolant. The steel core is internally treated with special polymer compounds, which reduces the risk of corrosion.

Undoubtedly, such models could be an excellent alternative to cast iron heating devices, but the high price does not make them popular and in demand. At least for now.

Generalization on the topic

As you can see, the range of radiators has increased significantly, and now you can choose the option that is most suitable for specific operating conditions. For those who live in apartment buildings and want to save on replacing heating appliances, experts recommend using only cast iron models. And steel and aluminum radiators can only be used in autonomous heating systems.

Not every battery is suitable for installation in apartment buildings, because frequent pressure surges in the system and the use of water as a coolant affect the performance of radiators. Some metals undergo corrosion and oxidation when they come into contact with water and air. The cast iron radiator remains tested.

Characteristics of cast iron radiators

• The material used is resistant to corrosion.
• Due to the resistance of cast iron to physical influences, batteries are used with any type of coolant. Its maximum temperature can be 150 degrees. Distinctive feature serves as oxidation resistance, because cast iron does not react when in contact with water, even if acid-base balance reaches 9-10 Ph.
• It perfectly accumulates heat, which increases its heat transfer when compared with other materials. Cast iron batteries retain heat for a long time after the coolant supply is turned off.
• The durability of heating devices is up to 30 years. At correct installation and care climate control technology lives longer than expected.
• Thick walls are the reason why cast iron radiators live a long life.
• The number of sections can be varied to achieve the required level heating
• If one section is damaged, only replace it, and not the entire battery.

Design modern devices heating differs from the usual old “accordions” that are installed in some apartments. Devices created using artistic casting and made in retro style are popular.

Suitable for three types of connection.

• Lower. With this connection, the pipes are connected to the lower outlets on both sides. Minus bottom connection– low circulation.
• Side. This connection method provides for maximum coolant circulation, since the pipes are connected to the outer section into the lower and upper outlets of one side.
• Upper. The pipes are connected to the upper outlets of the outer sections. The circulation with this connection is much higher than with the lower one.

Cast iron radiators are cast from an alloy of homogeneous mass, intended for use in heating systems of apartment buildings. Sections are manufactured separately and connected using engineered gaskets and nipples for tightness.

The heater power stated in the technical specifications almost always differs from the actual one. This is due to the testing of the radiator in laboratory conditions, which differ from real ones.

The heated coolant flows through the pipes of the heating system into the radiator compartments and heats the air in the room, releasing heat.

Types of cast iron radiators

• Single channel. In the design of radiators of this type, each section has a channel through which the coolant circulates. Climate control devices of this type are easy to clean, which is why they are installed in medical institutions.
• Two-channel. In one section of heating devices of this type there are 2 channels, which increases heat transfer.
• Three-channel. The heat transfer rates are higher compared to other species, while their weight and depth are much greater than those of their counterparts.

Two- and three-channel heating radiators use fins, which increase heat transfer. Sections can be stylized in different styles, from retro to futuristic. Sometimes a metal casing is used to hide the battery.

Double-channel heating radiators are popular because they are compact and have good heat dissipation.

Cast iron heating radiators are divided according to installation method:

• Wall-mounted. They are mounted on walls using reinforced brackets; this type of fastening is classic.
• Floor-standing.The batteries are supplied with four legs. They are part of the outer sections, so they are difficult to break off. These do not require additional fasteners, which will save the wall. In addition, not all walls can withstand cast iron. It is more convenient to clean after them, since the distance from the wall can be much greater than that of classical types fastenings.

In terms of height, on average, sizes range from 35 to 150 cm. The length depends only on your preferences, because the number of sections can be different, and the width directly depends on the number of channels.

Disadvantages of cast iron radiators

• Weight. This is the main disadvantage for cast iron products, and radiators are no exception. Because of the weight, and not because of aesthetics, the production of batteries with “legs” began, because not every wall is capable of supporting the considerable weight of cast iron.
• Thermos effect. They are classified as pros and cons. Cold radiators take a long time to warm up. When the heating is turned off, cast iron, due to the same property, remains warm for a long period of time and continues to give off heat.
• Water hammer. Some models of cast iron heating devices cannot withstand water hammer. The shocks occur in apartment buildings connected to a centralized heating system. This can be solved by installing a pressure regulator.
• Pollution. Cast iron batteries collect a lot of dust, and the design does not always allow for complete and high-quality cleaning.
• Appearance. Externally, cast iron devices are attractive, however, it is worth paying extra for beauty. Products made from this metal are sold unpainted, so the appearance is not attractive.

Ways out of this situation:

Paint the battery yourself. A painted battery may look unsightly if the layers of paint are applied unevenly.

Install a grill over the climate control unit. With the help of metal covers, you can “hide” the battery from prying eyes, however, such covers reduce the quality of heat transfer, and the room becomes cooler.

Order a cast iron radiator made in the style of an artistic cast. Batteries cast in different styles, do not need painting. This radiator is not suitable for all interiors.

Calculation of sections of cast iron radiators

Before purchasing a cast iron unit, you will need calculations that will allow you to more accurately determine required quantity sections. The example uses the following data:

1. The amount of heat generated by one section is 145 watts (the average figure is taken, the exact data is in the product data sheet).
2. The calculation is made for a room with normal insulation, one street wall and one window. According to SNiP, the amount of heat required to heat it is 100 watts.
3. The dimensions of the room are 4 x 3 meters.

Calculation

1. The area of ​​the room is determined. It is equal to 12 m2.
2. Multiply the area and the amount of heat needed to heat one square meter of room. According to SNiP, the room in the example requires 100 watts/m2. After performing this action, you get 1200 watts.
3. The amount of heat required for the room must be divided by the heat transfer of one part of the battery. Afterwards, round the result up.
4. The number of sections required for installation is obtained. For the room indicated in the example, a radiator consisting of 9 sections is installed.

The calculation is focused on rooms whose height does not exceed 3 meters.

Since each room is unique, there are coefficients that allow more accurate calculations:

To accurately measure the amount of heat per square meter, you need to divide the ceiling height by a factor of 3. For a room with a ceiling of 2.5 m, it will be 0.83.

For calculations, the average coolant temperature is used, which is 70 degrees. When this indicator increases, 15% must be subtracted from the final number every 10 degrees; when the temperature decreases, do the opposite.

If the room has not one, but 2 or 3 street walls, then it is worth multiplying the amount of heat for 1 m2 by a factor of 1.75. After this, the number of sections must be divided by the number of windows and radiators installed under each of them. This will ensure uniform heating of the entire room.

If the room has additional thermal insulation layers, as well as if double-glazed windows are installed, the amount of heat for 1 m2 is allowed to be divided by 0.8.

For houses located in regions with extreme low temperatures, the amount of heat for 1 m2 increases by 2 times.

Before installation cast iron radiator, you need to disassemble it into sections, check the fastening of the nipples, then reassemble it. You need to install it taking into account the weight of the battery and the material of the wall in the room. The minimum set of tools is an angle grinder, a hammer drill, an adjustable wrench, a building level and a die.

1. If the wall is brick or concrete, select fasteners that are designed to support the weight of the radiator with coolant. According to SNiP, the use of 3 or more brackets is recommended.

2. You cannot hang cast iron radiators on walls made of wood or plasterboard. because they may not be able to withstand the load. In this case, you can install the radiator on a floor stand or legs. It is attached to the wall only to maintain it in an upright position.

After installing the radiator, it is connected to the central heating using connecting sleeves and a conduit. Threaded connections It is recommended to seal.

Cast iron radiators must be periodically tinted with paint that can withstand heating temperatures without changing color.

Connection to the heating system:

1. Diagonal. Used when connecting multi-section units. The supply pipe is connected at the top on one side, and the return pipe at the bottom on the other.

2. Lower. Used when pipes are hidden in the floor of a room or behind baseboards. This is an aesthetic way to connect. The supply and return pipes are located at the bottom.

3. Lateral. The supply pipe is connected to the upper fitting, the return pipe to the lower one. Side connection has the greatest heat transfer. In case of poor heating in multi-section heating devices, it is recommended to install a coolant flow extension.

4. Consistent. The coolant moves under the pressure of the heating structure. Mayevsky taps are used to remove air. The disadvantage is the need to remove batteries and turn off heaters during repairs.

5. Parallel. The connection is made through a pipeline connected to the supply riser. The coolant leaves through a pipe connected to the return line.

We all know what cast iron heating radiators are, but not everyone knows their history, technical specifications, as well as how modern specimens differ from their predecessors. All this and much more will be discussed in the material below.

So, the first weighty radiator was presented to the world back in 1857, but its creator was the famous Russian engineer and entrepreneur of German origin, Franz San Galli. Of course, the batteries of that time were significantly different in appearance from those that we are used to seeing in our apartment. They were a pretty pipe large diameter having protruding disk elements. This structure was empty and was filled, however, like modern examples, with hot water. So despite the slightly different appearance, the essence still remains the same.

As you can see, such batteries have been popular for more than a century, but not every invention manages to stay afloat for such a long period. And all thanks to the fact that cast iron heating radiators have a very necessary for a person characteristics. One of the main advantages of this material is its corrosion resistance, thanks to which the internal surface of the heating device remains in excellent condition for many years.

In addition, it should be noted that the water entering the heating system your home, goes a long way and turns into a chemically aggressive environment. It is also possible that various abrasive particles such as pebbles, etc., may enter the system. However, even this is not a problem for cast iron batteries, so they are better suited for installation both in private buildings and in apartments of multi-storey buildings.

The next advantage that should not be ignored is the long operating period. You'd rather do it major renovation and replace old cast iron radiators with new heating elements that are more modern and suitable in design, rather than having to update them due to failure. After all, when proper care the service life can reach half a century, but in ideal conditions Such batteries will generally be able to celebrate a century in working order. True, manufacturers usually indicate in the characteristics a service life of no more than 30 years, but these data are underestimated.

It is also necessary to mention the inertia of cast iron. Such units heat up slightly longer than their analogues, while retaining heat for a long period, unlike the same aluminum batteries, which cool down literally in a matter of minutes, and the technical characteristics of steel are in many ways incomparable with cast iron. And thick walls and a fairly large internal cross-section not only have the most favorable effect on their thermal properties, but are also the key to long-term operation. And the cost of cast iron radiators is affordable for all segments of the population.

Everything is clear about the advantages, there really are a lot of them, but we should also mention the disadvantages inherent in such elements of the heating system. Let's start with the basics, one section has a mass of about 6 kg, so, using simple mathematics, we get the weight of a six-section cast iron radiator equal to 36 kg. But it is not always possible to limit yourself to just this number of segments. This weight will not only complicate transportation, but also the installation process. Firstly, it is really harder to work with it in the literal sense. Secondly, due to such weight, not every wall can support the battery. So, for example, if we are talking about, then it is better to play it safe and install radiators on special legs.

The next minus after weight is dimensions. Basically, these heating devices are quite bulky, which again complicates the installation process, steals the space of already small rooms and does not always fit organically into the design. In addition, to fill them, you need a large volume of liquid. Not the most best characteristic The heat transfer of all cast iron radiators is also the same. And all because it is only 20% dependent on the convention, and the remaining 80% is carried out due to thermal radiation. Therefore, if we compare them with analogues made from other materials, the designs of cast iron batteries should consist of a larger number of sections. And also due to the long cooling of the alloy, their joint work with thermostats is impossible.

Having discussed all the pros and cons, we can move on to another important question, namely, what technical characteristics are characteristic of such heating elements. Some may think that it is important to know only power, but much more will be interesting. Basically, they all have a sectional design, and the number of segments can be adjusted depending on the size of the room and desired results. However, there are also solid specimens. Inside, as mentioned above, the batteries are hollow, and a coolant flows through them, the maximum temperature of which can reach as much as 130 °C, although in practice this is not always the case, it can also reach 90 °C.

When calculations are carried out, parameters such as heat transfer and power of cast iron radiators are always taken into account. Moreover last characteristic mainly indicated for one section and is about 160 W. Already from this value their optimal number is determined if you know the desired power of the future battery. You should also say a few words about the width of one section, it is almost 10 cm, but the weight has already been mentioned, this parameter ranges from 5 to 6 kg. One more most important characteristic, which plays a decisive role is the crimping pressure, it reaches 15 atm. The working temperature ranges from 6 to 9 atmospheres.

The site’s site masters have prepared a special calculator for you. You can easily calculate required quantity sections.

One of the disadvantages that heating radiators of this type have was their bulkiness and, as a consequence, the inability to fit into modern interior. However, this is not entirely true. If we talk about standard inexpensive models, then you will surely face the above difficulties. Modern products harmonize much better with the ideas of designers and can not only lift your spirits with their original and colorful appearance, but will also easily add zest to the interior.

Batteries come in various shapes and have original castings of various patterns and ornaments. Incredibly interesting options are antique-style products that will fit perfectly into almost any interior, but best of all they will decorate a room designed in classic style. What about ordinary models, they can always be painted, while the variety color range makes it easy to choose the perfect shade. And bold experiments will provide an opportunity to decorate the room in an original way. Therefore, it is up to you to decide which batteries will decorate your walls.

Radiators can be solid or sectional.

Let's take a closer look at cast iron designs and which ones are better. The most common models are sectional, which are prefabricated devices. Their main advantage is the ability to adjust the dimensions and power by selecting the number of fragments. The next type is solid cast iron radiators. The advantages of this type include the absence of joints, which has the most favorable effect on the strength and tightness of the structure. But you won’t be able to adjust the power and dimensions; these parameters will be clearly defined. But this is not big problem, the main thing is to do it correctly preliminary calculations and buy a battery with a power that will immediately meet your needs.

So, cast iron radiators, the design and technical characteristics of which were discussed above, have been extremely popular for many decades, and today, despite the variety of thermal elements, their contribution to heating apartments is significant. And which of them are better suited for your purposes, you can easily determine.

“Everything new is well forgotten old,” people say, but not about cast iron radiators. The dimensions and parameters of old models formed the basis for improved designs made from this metal. It is not without reason that many consumers prefer to install stylish heaters instead of boring “accordions”, but again made of cast iron.

This is due to the fact that for several decades these radiators have been reliable allies in the fight against the cold.

General indicators of cast iron radiators

In truth, it is this metal that heating devices are most suitable for “survival” and long-term operation in conditions of centralized heating. Since 1857, when cast iron radiators were invented, they have brought heat to the homes of people in different countries. Currently Western countries They stopped using this metal for heating homes, but in the CIS most houses built in the 60s and 70s are still heated with their help.

The parameters of modern cast iron batteries are the same in some respects, although both they and older models have their own advantages and disadvantages.

• The level of heat transfer and power are the first points that consumers pay attention to when choosing heating devices for their homes. These indicators are largely influenced by the size of cast iron heating radiators, but the average power of one section is 140-160 W.
• Low inertia ensures uniform heat radiation and long-term cooling of the structure when it is turned off.
• The size of the cast iron radiator section affects its weight. There are elements that weigh 3 kg, and there are also those that weigh 7 kg.
• Medium-sized heating devices made of cast iron have become a classic standard. So the width of the cast iron radiator section is 80-100 mm, the height is from 370 mm to 570 mm, and the depth is from 70 mm to 120 mm.
• The volume of old types of radiators is 1.5 l, for domestic models of the new generation it is 0.7-0.8 l, and for foreign analogues– 0.4-0.6 l.
• Working pressure is another important factor, which should be taken into account when installing radiators. So for Soviet models it was 6-9 atmospheres, and the wall thickness and size of the new type of cast-iron battery can withstand a load of up to 12 atmospheres. Some manufacturers are disingenuous when they indicate that their cast iron products working pressure is 15-18 atmospheres. This is actually the testing pressure that every battery is subjected to at the factory to test its resistance to water hammer.
• The stated warranty period for cast iron radiators is 20-35 years, although there are companies that give their products 50 years of operation, and this is not surprising. Such a long active “life” of these devices is due to the presence of a wide channel through which the coolant passes without difficulty, without leaving debris at the bottom and corrosive scale on the walls.

These are the main indicators that are inherent in many models, but since today there are manufacturers from different countries on the market, the size of the cast iron radiator section may differ, its weight, and other parameters.

Main dimensions of cast iron batteries

Although the main criterion, which is accepted by all manufacturers, is the center distance, there are products that, with the same parameter, have differences in height, depth and width.

Key indicators:

• The center distance is quite varied. It can vary from 220 mm to 900 mm.
• The height of the cast iron battery ranges from 330 mm to 950 mm.
• The depth is 85-200 mm.
• There are products with a width from 45 mm to 100 mm.

Given such a wide range, all products are divided into low, high and standard cast iron radiators. In each of these model ranges you can find the usual “accordion”, and antique products, and chic palace or modern styles, or modern samples with a flat outer panel.

As a rule, for low models, a place is found in rooms with panoramic windows, or where the walls are weak, for example, made of plasterboard. Their center distance does not exceed 30 cm, and their height is 38.8 cm. On the domestic market they are represented by models such as MS-110 and 90. Modern low analogues have a basic center distance of almost 40 cm. The most popular are products from such manufacturers as like Bolton220 (Turkey) and Viadrus (Czech Republic) - 34 cm.

The height of a standard size cast iron radiator is based on a center distance of 50 cm. If you choose a Soviet “accordion” of the usual type for your apartment, then domestic manufacturers produce them under the following markings: MS-85 and 90, MS-110 and MS-140.

In this segment you can most often find designer models in old style. They are expensive, but they look impressive and heat wonderfully.

You should not look for a section size of a cast iron battery that is too high. Although new devices weigh half as much as old ones, radiators made of this metal cannot be found above 1 m. In this model range The leaders are cast iron batteries from the company Demir Döküm (Türkiye). Their designs are original, highest quality cast iron and high cost.

Before making a choice, you should carefully study the product data sheet and become familiar with its main parameters. Since any installation of radiators is preceded by a calculation of the power based on the area of ​​the room, and their size directly affects this parameter, you should immediately check all the indicators so as not to subsequently purchase or remove sections.

MS-140 – main parameters

Today, of all the models that were installed at one time in apartment buildings, the most popular of them remains - MS-140. The lowest center distance had cast iron radiators 300 mm, and the highest - 800 mm. Currently, factories produce only batteries of two parameters - MC 500 and 300.

Key indicators:

• Working pressure 9 atmospheres.
• Heat dissipation up to 175 W.
• Consists of two-channel sections.
• The cast iron radiator 500 has a height of 50 cm and a width of 9.8 cm.
• The coolant volume is 1.35 l.
• Heating of the coolant up to +130 degrees.

Thanks to these parameters, the MS-140 is in demand among the population. His low cost and high reliability, proven over decades.

Heating radiators STI nova

If you are looking for stylish cast iron batteries from a domestic manufacturer, you won’t find a better one than the new STI. Their main parameters:

• The cast iron radiator Nova 500 can withstand pressure up to 18 atmospheres. Crimping pressure of 16 atmospheres allows you to survive water hammer centralized system heating
• The thermal power of the structure is 150 W, which is enough to provide heat to a room of 15 m2.
• Externally, the Nova 500 heating radiator (cast iron) looks as stylish as its aluminum counterparts.

If you believe consumer reviews, this type of heating device is distinguished by its quality, reliability and interesting design.

Cast iron batteries Konner

Another “favorite” of the public is the Konner company, which was able to find its place in the Russian market. A fairly wide variety of models, their price and reliability earned it fame.

Main product parameters:

• Thermal power ranges from 120 W to 180 W depending on size. For example, a 300 mm cast iron radiator from this company produces 120-130 W of heat.
• Water heating +110 degrees.
• The working pressure is 12 atmospheres, and the test pressure is 20 atmospheres.

The size and stylish appearance make it possible to install batteries of this type not only under windows, if the design of the room requires it.

Today there are dozens of manufacturers of cast iron batteries on the market. All of them correspond to the parameters of the domestic heating network and have affordable price, are reliable in operation and look great in the interior.
