Which radiators are better for an apartment: market analysis

Which radiators are better for an apartment: a detailed analysis of the modern market

The choice of heating batteries is a serious event, on which not only the efficiency of heating residential premises depends, but also the operational life of heating communications as a whole. In multi-apartment buildings, the risk of water hammer is higher than in private homes, which is due to the connection to the centralized heating network. Therefore, the article will consider in detail the question of which radiators are better for an apartment.

When choosing a radiator, it is necessary to take into account the peculiarities of domestic heating systems, as well as to choose the right material, power and number of its sections

Features of centralized heating networks

The supply of coolant to the apartments is carried out by connecting to the centralized heating network (DSP). The movement of the coolant in such systems occurs in a forced manner. The liquid supply to each apartment is carried out by special pumps that are part of the DSP. The pressure pumped by the pumps averages 16 atmospheres.

When choosing radiators, it should be taken into account that the pressure of the coolant is not constant

Useful information! When choosing a radiator, first of all it is recommended to pay attention to how often pressure surges occur in the communication. In order for the battery to be able to withstand a water hammer, its material must have a sufficient margin of safety.

A fairly common phenomenon to which centralized communications are subject is a violation of conservation. As a rule, this happens in the summer. At the same time, not all batteries are able to withstand water shocks that occur during such depressurization in the system.

Individual elements of the DSP wear out greatly over time, which leads to deterioration of the quality of the coolant and the ingress of various foreign impurities into it. They can be technical impurities, rust particles, dirt and various sedimentary elements. The presence of the former in the working environment negatively affects its thermal output during circulation through the DSP. The rest contribute to narrowing the lumen of pipes and heating batteries, which also reduces the efficiency of heating residential premises.

When replacing the heating device in the apartment, check the compatibility of the materials from which the batteries and connecting elements (fittings) are made. Incompatibility of metals leads to their oxidation, which often causes emergencies in the DSP.

Any radiator must function in conditions of frequent filling and draining of the system

Which radiator to choose: types of heating batteries

To date, you can find a variety of batteries for installation in apartments. All of them are divided into types according to several criteria. First of all, all radiators are classified according to the material from which they are made:

• cast iron;
• steel;
• aluminum;
• bimetallic;
• copper.

And also, depending on the design, they can be:

• sectional;
• panel.

Each of the above types of heating devices is suitable for use in certain conditions. It is also worth saying that there are highly specialized models that are used to perform a single function. This type can include floor-type convectors used in rooms that have a large glazing area. Their use makes it possible to eliminate the possibility of fogging windows.

When deciding which radiators are better for an apartment, it is preferable to choose devices that have more heat output

On the market, you can also find another type of convectors – baseboard. They are installed in special metal boxes that replace the classic baseboards. The main advantage of such heaters is that they do not disrupt the overall interior of the room.

Today you can meet a variety of batteries, from the point of view of design. The range of modern radiators is incredibly wide and diverse. The disadvantage of batteries made in a unique design is their price. Therefore, such heating devices are not in high demand.

Characteristics of cast-iron batteries for apartments

Not so long ago, cast iron heaters were the most popular and were used almost everywhere. But today these bulky structures, covered with enamel paint, have receded into the background. With the development of production technologies, more efficient and wear-resistant steel radiators, as well as devices made of other materials, have appeared.

Pay attention! Cast iron material has a high coefficient of thermal conductivity. And it is also worth saying that it heats up for a long time, but it also cools down for a long time.

Among the advantages of cast iron is its inertial heat transfer, especially increasing due to an increase in the thickness of the metal

Cast-iron batteries are able to withstand a fairly high pressure (up to 30 atmospheres), which exceeds the standard DSP indicators by 2 times. Thus, devices made of this material are highly resistant to water shocks in the system.

Among the advantages of radiator batteries made of cast iron, it can also be distinguished that they are compatible with pipes and fittings made of other materials. This allows you to save money, since there is no need to replace the associated communications when replacing the battery.

And also cast iron products are distinguished by their resistance to destructive corrosive influences. They are unpretentious in terms of the quality of the working environment that moves through them. Prolonged interaction of the inner surface of the battery, made of cast iron, with water leads to the appearance of a dark precipitate, which has an antioxidant property. Therefore, with the normal use of such radiators, they are able to last for more than a dozen years.

Modern radiators made of this material are coated with a special protective enamel at the production stage. Unlike the old cast-iron batteries, the new models do not require annual staining, and are also easy to clean, as they have a smooth, glossy surface. Among other things, cast-iron heaters do not accumulate gases, so they do not need to drain excess air.

The ability to withstand high pressure and water hammer is a positive characteristic of cast iron radiators

In Soviet times, such radiators were manufactured in large quantities and had standard sizes. Today, the range of these devices offers customers virtually unlimited options for cast iron products that differ in shape, design and color. A wide range allows you to increase the operational area of such radiators.

Western companies engaged in the production of cast-iron radiators produce special design lines of heating devices. Such batteries are made in a fashionable retro style and are equipped with various ornaments. Of course, the cost of such products is an order of magnitude higher than ordinary cast iron, but their quality and presentable appearance are beyond doubt.

Cast-iron structures are selected, depending on the dimensions of the room. If necessary, the number of sections can be increased or decreased, which is very convenient. Let’s consider what factors influence the choice of the number of sections:

• room area;
• window size;
• number of doors;
• features of the climatic region.

Cast–iron radiators are durable – their service life, with proper operation, is at least 50 years

Cast-iron structures also differ in the volume of filling. For example, in domestic radiators it is 1.3, and in foreign – 0.8 liters. The cost of the latter is about 2-3 times higher. Brackets are used to install radiators in an apartment made of cast iron. It is also worth noting that some models are attached directly to the floor.

Why it is better to refuse to buy cast iron: an overview of disadvantages

As mentioned above, cast-iron radiators are not as popular as before. This is due to their shortcomings. The main disadvantage of these products is their heavy weight, due to which their storage, transportation and installation are accompanied by certain difficulties.

Pay attention! To mount a standard cast–iron structure, it is necessary to use bulky locking elements – brackets.

It is also worth mentioning that, from the point of view of design, standard cast iron products are not too presentable. They are categorically not suitable for rooms made in a modern style. Another disadvantage of cast iron heating batteries is low inertia. With such a battery, it will not be possible to perform operational regulation of the temperature regime in the room, and for autonomous heating systems this property is especially important.

The disadvantages of cast iron batteries are their heavy weight and not particularly aesthetic appearance

Cast-iron structures do not differ in strength characteristics and are particularly susceptible to mechanical influences (impacts). It is precisely because of the above properties that these products are not in great demand in the modern market of heating equipment.

Varieties of steel heating batteries for apartments

Steel radiators are among the most popular today. They have a lot of positive qualities, and are also quite presentable and suitable for almost any room design.

There are three main varieties of these products, which differ from each other in their design:

• panel;
• tubular;
• lamellar.

Each of these types is suitable for certain conditions and has its advantages and disadvantages. In order to answer the question of which radiator is better to choose for an apartment, it is necessary to consider the features of both panel and tubular, as well as convector structures.

Depending on the model, manufacturer and many other factors, a tubular heating radiator can have a wide variety of technical parameters

Which radiators are better for an apartment: panel batteries made of steel

The panel structure includes two steel sheets. By stamping, they are given the necessary shape. After that, the resulting blanks are joined by welding, which allows you to get a hollow panel. If necessary, it is supplemented with convectors, thanks to which the air moves in a vertical direction. This allows you to perform a kind of “barrier” that protects the room from the cold coming from the window.

After assembling such a radiator, it is painted. The protective coating is a very important element of the structure, as it protects it from corrosion, makes it more presentable, and also contributes to its care. When choosing a new steel battery, it is necessary to pay special attention to how evenly the paint layer is applied to the panel. It should not contain gaps, cracks or chips.

Steel structures are able to withstand the temperature of the working environment up to 95 ° C. They are designed for the standard pressure that is created inside the DSP, namely: 16 atmospheres.

Useful information! Steel batteries of this type can have a different number of convector elements and panels.

Panel radiators are made of two stamped metal sheets connected in such a way that channels are formed between them through which the coolant circulates

The length of such radiators ranges from 40 cm to 3 m. The minimum height of such a structure is 20 cm, and the maximum is 90. Some companies are engaged in the production of steel heating devices of this type to order, which also expands their model range, and, accordingly, the operational sphere.

Description of the principle of operation, comparison of heaters. Overview of types, firms and prices of convector heaters.

Depending on where the heating device will be docked with the pipe, there are two main variants of steel devices:

• with lower connection;
• with side connection.

When choosing a steel radiator, it is necessary to pay attention to the location of the wiring of heating pipes in your apartment. Based on this, the necessary design is selected, with the desired connection option.

Characteristics of the panel radiator

Advantages and disadvantages of panel radiators made of steel

In order to answer the question of how to choose a radiator for an apartment, you need to familiarize yourself with the pros and cons of steel panel structures. Such models are the most common today. To begin with, let’s consider the positive qualities of these heating devices.

The first and perhaps the most important advantage of the panel design is the simplicity of its installation. Installation in the heating circuit is carried out according to the instructions quite quickly. If necessary, you can do it yourself. In addition, the radiator design eliminates the need for assembly, as it is one-piece, which also saves time.

Panel radiators are characterized by high inertia, so they warm up very quickly. Thanks to this, they can be easily adjusted to the required temperature regime. And also such steel structures have a fairly large area, which contributes to the rapid and efficient heating of the room.

Steel batteries in the form of panels are compact in size and have an attractive, modern appearance. Such models are the most suitable for apartments equipped with an autonomous heating system. This is due to the fact that a minimum amount of coolant is required to fill them.

The disadvantages of panel radiators include low operating pressure, high sensitivity to various kinds of impacts, including hydraulic ones, as well as vulnerability to corrosion

Like any other products, steel panel batteries have their drawbacks. The main one is that they are not designed for strong hydraulic shocks. They differ in reliability only at normal pressure values in the DSP. However, this problem can be dealt with. When installing a panel structure in an apartment, it is recommended to use a special device – a reducer. This device allows you to reduce the load level on the panel during a water hammer.

The inner walls of such radiators, as a rule, are not equipped with a special protective coating against corrosion. It follows from this that their shelf life will depend on how high-quality coolant circulates through them.

Tubular (sectional) steel batteries

Unlike the previous type of steel radiators, such batteries include several sections. The fixation of these elements with each other is carried out by welding. Such products do not need to be assembled, which is undoubtedly their advantage.

Pay attention! How to choose a tubular type battery? Before buying a tubular heater, a mandatory item is the selection of the required power. This indicator is calculated taking into account the total area of the room that the sectional model will heat.

 

Diagram of tubular (sectional) steel batteries

Sectional heaters are used in systems whose pressure ranges from 8 to 10 atmospheres. As a rule, this is not enough for apartment buildings heated by DSP. Therefore, experts recommend using such models to purchase a gearbox that is able to protect the tubular battery from water shocks.

The standard wall thickness of sectional gearboxes is 1-1.5 mm, so they have a high coefficient of inertia. But the small thickness of the walls is also a disadvantage of such products, since they differ in rather weak strength characteristics.

Tubular type structures are characterized by good resistance to the contaminated medium of the coolant. Unlike panel models, their inner surface is equipped with a special protective layer of polymer material at the production stage. Due to this, they are resistant to corrosion and have a longer service life.

Such devices are available in different sizes. The width depends on the area of the room and the number of sections. The height can vary from 0.2 to 2.5 m, and the depth – from 10 to 25 cm.

Basically, tubular radiators are made of high-quality steel, which has a light weight and is able to withstand heavy loads

Sectional products have two main disadvantages:

• low heat transfer coefficient;
• the presence of welds that are unstable to hydraulic shocks.

Thus, sectional batteries are a good option for installation in autonomous heating utilities. However, they are not quite suitable for use in DSP conditions, since they are susceptible to water shocks.

The choice of tubular batteries, depending on their design

Many apartment owners are interested in the question of which radiator to choose, depending on the design. Tubular batteries made of steel (and not only) are a common solution for installation in an apartment. The range of such devices is distinguished by a variety of design solutions. Depending on the location of the sectional radiator, you can purchase a wall or floor product.

Such devices are mounted at different points of the living space. For example, the most common option is to install a tubular battery under the window, however, if desired, the location can be any. They are often used for mounting in the center of the room (vertical version). In this case, the height of the battery corresponds to the height of the ceiling.

With the help of tubular radiators, you can not only fully heat the room, but also make it more attractive

Useful information! Some sectional radiators include special wooden panels that are mounted at the top of the device and function as a work surface. Such a shelf can be adapted for a variety of needs, but most often it is used to dry shoes.

The presence of a wide range of shapes, a variety of color solutions and the presence of additional structural elements significantly expand the operational scope of such steel products.

Plate radiators made of steel (convectors)

The working medium in the plate radiator moves along straight or curved steel pipes. Plates made of the same material are attached to them. The purpose of these elements is to increase the thermal output of the structure.

Plate batteries are resistant to hydraulic shocks. And it is also worth saying that the steel rods located inside the structure are heated to fairly high temperatures. However, they are covered by a protective casing, the temperature of which is no more than 40 ° C.

Such designs are great for use in rooms with high ceilings. This is due to the fact that the heated air is steadily moving upwards and can rise to a fairly significant height. If necessary, you can independently adjust the temperature regime in which such a heating device will function.

Plate heaters are so called because they are made of several plates mounted on curved or straight pipes

Plate batteries are capable of withstanding standard pressure in the DSP (16 atmospheres). And the maximum pressure indicator for them is 24 atmospheres. It follows from this that convector structures are suitable for use in apartment buildings. The price of a battery for heating of this type averages 6-9 thousand rubles.

Such heating devices have some disadvantages. For example, the vertical orientation of the heated air movement is not only the positive, but also the negative side of the plate product. This is due to the fact that the heating of the room is performed unevenly.

The convector plates are very quickly polluted with dust, which affects the heat transfer coefficient. Cleaning these elements is a rather difficult undertaking. And it is also worth noting that such devices do not differ in aesthetics and are not suitable for every interior. Such batteries are most suitable for installation in rooms that have high ceilings. They are often installed in corridors, swimming pools, etc.

Which radiators are better for an apartment: an overview of aluminum models

Structures made of aluminum differ in their appearance, as they have a stylish design. However, such products are not the best option for installation in apartments with DSP. This is due to the fact that the aluminum structure has rather thin walls that are unstable to the destructive effects of corrosion. Given the low quality of the coolant, such a battery may fail after 5 years of operation.

Aluminum radiators, neat and stylish, consist of several sections connected by nipples

Useful information! For apartments that are heated by autonomous heating communications, an aluminum radiator can be a good option. A high coefficient of thermal conductivity, as well as a presentable appearance are the main advantages of such products, thanks to which the demand for them remains good.

Aluminum models are designed for operation in systems with a pressure of 15-20 atmospheres. However, the thin-walled structure used in the DSP cannot boast of resistance to hydraulic shocks. Considering this fact, it is worth saying that a radiator for a house of this type is best suited for installation in conditions of autonomous heating.

Experts advise not to use such batteries if the pressure in the communication exceeds 12 atmospheres. As for the quality of the coolant, aluminum structures function best at a Ph of 5-6 units, which is a rarity in domestic DSP.

Such heating devices are characterized by a small mass, therefore they are easy to store, transport and install. It is important to remember that the installation of such a battery requires not only care, but also the selection of fittings made of compatible material. Otherwise, areas affected by corrosion will form at the docking points. Consider the materials that absolutely cannot be used when installing an aluminum battery:

• steel;

Aluminum batteries are subject to corrosion processes, so the inner layer of radiators must be protected from contact with the coolant

• brass;
• copper.

The ideal option for installing an aluminum radiator is a heating circuit made of plastic. In this case, the occurrence of corrosion is excluded, and the heating structure itself is easy to repair or dismantle.

Today you can find a wide selection of aluminum products. They differ in size, color and design. The height of such products ranges from 25 to 50 cm, however, if necessary, you can order a non-standard model (70-80 cm).

Experts note that such batteries have excellent compatibility with temperature-regulating equipment. When installing an aluminum structure, it is recommended to select a thermostat in advance. And they also have a glossy surface, so in case of contamination, it will not be difficult to clean such a radiator. How to choose an aluminum heating battery, depending on the brand?

If we talk about companies that produce aluminum radiators, then the most popular among consumers is the ROYAL THERMO company. Products from this brand are of good quality and reasonable cost. Such radiators are adapted specifically for use in the CIS countries. They are characterized by good corrosion resistance and a long service life (above 10 years).

Lightweight, with excellent heat dissipation models of aluminum batteries attract consumers not only with their technical characteristics, but also with a pleasant appearance

Aluminum batteries with anodic coating are an ideal option for an apartment

Heating devices made of aluminum can be made with a special anti-corrosion coating, which is called anodic. For the production of such batteries, a high-quality aluminum alloy is used, which is pre-cleaned, and a layer of oxidized anode is applied to the surface.

The technological process of manufacturing such products is quite complex. During it, the structure of aluminum is changed several times, which is a kind of hardening. Thus, the final product is characterized by increased resistance to corrosion and can be used in DSP conditions.

Such radiators are made by casting. After that, the resulting sections are assembled into a single structure. One of the main advantages of such products is that, if necessary, you can repair the radiator in the apartment. Replacing the section that has been damaged is quite simple due to the design of the heater.

Useful information! If necessary, additional sections can be added to the anode battery.

Aluminum batteries with anodic oxidation are produced from metal that has undergone the process of ematalization

The inner walls of such models are smooth, which contributes to heat transfer. The coolant moves through the aluminum structure without any difficulty. The working pressure of anode products is 20-25 atmospheres, which is much higher than necessary in an apartment building with a DSP.

When purchasing such a heating device, experts advise to be careful. This is due to the fact that anode products look no different from conventional cast radiators. Therefore, before buying a particular model of this type, it is recommended to familiarize yourself with the documents for it. Checking the passport and quality certificate allows you to avoid problems when buying an anode radiator.

Bimetallic radiators: which are better for an apartment?

Bimetallic batteries are the most popular in the modern market of heating equipment. They have many positive qualities, among which versatility is worth noting separately. From the name it becomes clear that two metals are used in the production of such heating devices. Combined manufacturing allows to significantly improve the performance characteristics of these products.

The outer part of the bimetallic structure is usually made of aluminum. This makes it possible to achieve high heat output and increase heating efficiency. In turn, the internal channels necessary for the circulation of the coolant are made of high-quality steel, which is resistant to corrosion.

Bimetallic radiators are made of two main components: the internal elements are made of high—quality steel, and the external ones are made of aluminum

Separately, it should be said that the outer part, made of aluminum, is additionally provided with a layer of enamel, which gives such radiators a presentable appearance. Bimetallic batteries have a sectional design. The docking of individual elements is carried out by means of coupling couplings, which are equipped with sealing rings.

The long operational life of bimetallic heating devices is determined by their structure. The aluminum shell does not come into contact with the working medium and performs the function of a kind of “case” for internal steel channels through which the coolant moves.

The steel part of the bimetallic radiator is characterized by high resistance to loads in the system. Such products are capable of functioning at very high pressure values (35-40 atmospheres). Due to this, they are excellent for installation in apartments that are heated by a DSP.

And also such radiators have a small mass, which simplifies their installation in the apartment. Of the disadvantages of such products, perhaps only one can be noted – a rather high cost. However, their quality characteristics and shelf life fully justify the price.

The appearance of bimetallic radiators is sometimes compared with analogues made of aluminum, but the former will cost much more

If we talk about choosing the best bimetallic radiator for an apartment, then it is necessary to pay attention to several popular models. Among them: SIRA RS BIMETAL 500, GLOBAL STYLE PLUS 500, as well as RIFAR MONOLIT 500. Each of these models has proven itself well in working in an apartment building with a central heating circuit.

Which heating batteries are better for an apartment: prices and features of copper batteries

Batteries made of this material occupy the smallest segment in the heating appliances market. Their low popularity is primarily due to the fact that they are quite expensive. However, they are distinguished by high technical characteristics and in this they can compete even with bimetallic products.

Such batteries are made of high-quality copper material that does not have foreign impurities that can reduce the efficiency of the device. Such radiators have a number of positive qualities, although they are rarely used when replacing radiators in an apartment. The main advantage of such products, of course, can be called high efficiency, which is 4-5 times higher than that of cast-iron models.

Another advantage of heating devices made of this material is a high coefficient of inertia. They are able to warm up quickly, which contributes to effective heat transfer. As well as copper structures are characterized by high strength characteristics and resistance to hydraulic shocks. They are able to function in systems with a pressure of 20-25 atmospheres, which exceeds the standard indicators in the DSP.

The heating system with copper batteries is not afraid of water shocks – the softness of the metal contributes to the uniform distribution of loads and prevents depressurization

Useful information! If the coolant is not water, but antifreeze, then the use of copper radiators is the only solution.

And it is also worth noting that such heating devices do not need to be painted, since they have high anti-corrosion qualities. The operational life of copper products exceeds 10 years. They have a presentable appearance and thanks to this they can become an ornament of any interior, especially decorated in a classic style.

It is important to remember that for such batteries it is necessary to select fittings from the same material in order to exclude the possibility of an oxidation reaction.

Vertical radiators for apartments made of different materials

Vertical radiators have several advantages over devices that are mounted in a standard way. They are light in weight, versatile and easy to install. High batteries are an excellent solution if the free wall space is not enough to install a conventional device. Vertical models are made of different materials:

Cast iron. High heating devices made of this material are quite unpretentious. The quality of the coolant does not matter to them. They are distinguished by a good heat transfer coefficient, as well as resistance to hydraulic shocks. They are located in the middle price segment. Of the disadvantages of such high batteries, it can be noted – a large mass, which makes it difficult to install them.

The material used for vertical radiators has no restrictions, they can be metal, bimetallic, glass, wooden, stone

Steel. Experts recommend using panel steel structures in apartments. The wall thickness of such batteries ranges from 1 to 1.5 mm. The outer walls of such products are equipped with a protective layer of enamel, which also gives them aesthetics. High radiators made of steel are susceptible to hydraulic shocks and are most often used in private homes equipped with an autonomous heating circuit.

High heating devices are distinguished by their efficiency and aesthetics. You can buy a vertical radiator for an apartment in any profile store or place an order online. When buying steel devices, it is recommended to pay special attention to whether they have a protective anti-corrosion layer.

Aluminum. High aluminum batteries are low temperature. They provide heating of the room due to their dimensions. The temperature of the working environment in such radiators ranges from 60 to 70 ° C. They are capable of providing a standard temperature regime in the room (from 20 to 24 ° C). Aluminum vertical heaters are light in weight, and also have the ability to add sections. Such products are most often used in autonomous heating circuits.

Bimetallic. They are characterized by high quality and efficiency due to the use of two metal shells (aluminum and steel). They are best suited for use in multi-family residential buildings.

Vertical radiators can be made in the form of sections and monolith, fixed size and customized

Which heating battery to buy for an apartment: the main selection criteria

Before buying a heating device for an apartment, it is necessary to pay attention to several main points. There are certain criteria, the study of which will answer the question of how to choose a radiator. Heating batteries must meet all the necessary technical specifications, have a passport and instructions.

Let’s consider the main factors for which it is necessary to choose a battery for an apartment.

Working pressure. The documentation for the heating device must necessarily indicate the operating pressure. Experts recommend purchasing batteries with a certain margin. The working pressure of the battery should exceed the same indicator in the central heating circuit by about 1.5 times. This will allow you to be safe, since pressure surges often occur in the DSP.

Pay attention! In five–storey buildings of the old model, the pressure in the heating circuit is about 6-8, and in modern high-rise buildings – 10-15 atmospheres.

Resistance to hydraulic shocks. This factor has a direct impact on the operational life of heating equipment. If a gearbox is not installed in front of the radiator, then hydraulic shocks will affect the structure with full force. When choosing a battery, it is recommended to take into account the specifics of the heating circuit in your home.

In apartments with centralized heating, it is recommended to use cast-iron radiators, which are most resistant to corrosion and have a long service life.

Number of sections. If, when choosing a heating device, there are difficulties with determining the required number of sections, then it is recommended to pay attention to models that can be “increased” if necessary.

Power. This indicator is perhaps the most important. Not all heating devices are able to maintain the required temperature regime in a residential area. This is especially problematic in the northern regions, where the temperature can drop 40 °C below zero. In such situations, experts advise to select models that are able to withstand the high temperature of the coolant (up to 130 ° C).

The temperature in the radiator of heating in the apartment must meet the necessary standards and provide a suitable microclimate in the room. To date, it has been established that the temperature of +18 °C is considered the norm for residential premises. For corner rooms, the walls of which are in direct contact with the street, this indicator is increased by 2 °C. Therefore, when choosing a heating device, it is necessary to calculate its power taking into account specific operational features.

The composition of the coolant. Also do not forget that the shelf life of the battery is influenced by the characteristics of the working environment circulating through it. High quality coolant is a rarity. As a rule, it includes various harmful (for radiator walls) impurities. Thus, it is necessary to select a structure with thick walls or a protective coating.

Today, innovative solutions have come out to replace the old cast–iron and standard steel batteries – designer radiators that surprise with a variety of their shapes, colors and mounting methods

Radiator design. This factor is completely individual and depends on the preferences of the owners of the apartment, as well as the features of the interior.

Easy to install. Such a criterion is not among the necessary ones. However, if you decide to install the heating structure yourself, then it is worth selecting products that have a small weight. And also to study the options of fasteners and the features of connecting a particular model to the heating circuit.

Which heating batteries are better for an apartment: professional advice

So which radiators are better to put in the apartment? Experts recommend consulting with a plumber before purchasing a heating device. In any case, you will need to know the features of the DSP and the coolant, among which:

• pressure in the heating circuit;
• Ph of the working environment;
• The temperature of the coolant.

After receiving all the necessary information regarding the heating circuit, it is recommended to inquire about the jumps occurring in the system. This data will help you choose the right radiator for the parameters.

In order to choose the right type of radiator for an apartment, it is necessary to study the characteristics of each of them

Useful information! For residential buildings that have more than 12 floors, an excellent option would be to install a bimetallic battery. Cast-iron models can also be used in this case. If the working pressure index does not exceed 14 atmospheres, and the Ph value is in the range from 5 to 8, then not only cast iron and bimetal, but also aluminum and steel can be used.

If the acidity index exceeds the permissible level (>8.5), then the use of steel and aluminum structures is categorically not recommended. In such an environment, only bimetallic heating structures can function normally. They are also suitable for DSP, the pressure in which exceeds 20 atmospheres.

Rating of radiators for apartments made of bimetal

Among bimetallic radiators, as mentioned above, there are three main models. Consider their characteristics:

SIRA RS BIMETAL 500. Such a model has several main advantages, which include: a high heat transfer coefficient, as well as good sound insulation qualities. Similar products are made in Italy. They are able to provide heating of a room with an area of up to 40 m2.

The number of sections in such batteries varies from 4 to 12. As well as bimetallic radiators of this model are distinguished by high quality of painting and aesthetics. Among the disadvantages, we can note an increased sensitivity to the working environment.

Wanting to replace the old radiator with a better quality device with decent characteristics, a person inevitably faces a difficult choice – which model to purchase

GLOBAL STYLE PLUS 500. Bimetallic heating device from an Italian manufacturer, characterized by high build quality. The operational life of such products is 25 years, as reported by the manufacturer. Another advantage of such a radiator is its resistance to hydraulic shocks. The model of this type is capable of withstanding pressure up to 35 atmospheres. The maximum temperature indicator of the coolant for this heating device is 110 °C.

The main disadvantage of such batteries is the enameled coating, which is characterized by uncertain quality. And it is also worth saying that the price of a heating battery of this type is higher than that of other representatives.

RIFAR MONOLIT 500. The most popular bimetallic radiator, which is highly resistant to hydraulic shocks and has an operating pressure of as much as 100 atmospheres. The company “Rifar” is located in Russia and specializes in the production of heating devices adapted to domestic conditions of use.

Such a model can have a different number of sections. The maximum heat transfer rate of such a battery reaches 2744 watts, which is quite enough to maintain the necessary microclimate in a room with an area of 27 m2. The maximum temperature of the working environment that such a battery can withstand is 135 °C. Of the disadvantages of this radiator, weak noise insulation can be distinguished.

Evaluating the products of the GLOBAL brand, experts say that the company confidently occupies a leading position in this industry in terms of price-quality ratio

Which radiators are better for an apartment: prices and characteristics of aluminum models

In turn, aluminum heating structures have many varieties. Consider those of them that are most popular among buyers:

THERMAL RAP-500. The company that produces this model of radiators is located in Russia. Products of this type are designed to work in rather difficult conditions. The maximum operating pressure for the RAP-500 model is 24 atmospheres, which exceeds the standard values in the DSP.

Pay attention! When buying an aluminum heating device, it is necessary to pay attention to its operating pressure. This indicator is indicated in the relevant documentation attached to the radiator.

The aluminum battery of this model is resistant to hydraulic surges, therefore it is popular among buyers in Russia. The maximum temperature of the working environment that the RAP-500 radiator from the THERMAL brand can withstand is 130 °C.

RIFAR ALUM 500. Such aluminum batteries, as in the previous case, are manufactured by a Russian company. They are able to function in severe temperature conditions (up to 135 °C). The maximum area that a model of this type can heat is 25.6 m2.

The RIFAR ALUM 500 radiator model is adapted to the extreme climatic conditions of any region

The aluminum model from this manufacturer can withstand pressure up to 20 atmospheres and is resistant to minor hydraulic shocks in the DSP. Its operational life can reach 25 years under normal use. The main disadvantage of this model is a low–quality protective coating.

ROYAL THERMO REVOLUTION 500. The aluminum radiator from the Italian brand ROYAL THERMO differs in that it has the best heat transfer coefficient among similar designs. The maximum power of such a heating device can reach 3982 watts.

The installation of such an aluminum radiator allows you to provide the necessary temperature regime for rooms with an area of up to 40 m2. This model is suitable for use in DSP, the operating pressure of which does not exceed 20 atmospheres. Thus, we can conclude which radiator is better for the apartment. The price and photo of such a battery can be easily specified on the Internet.

One of the disadvantages of this heating equipment is that they are quite demanding on the quality of the working environment. The approximate cost of the above devices ranges from 2500 to 5000 rubles. There are also more expensive options, the price of which can reach 12,000 rubles. and even higher. These include vertical aluminum heating devices.

The main emphasis of the manufacturer of the ROYAL THERMO REVOLUTION 500 model is on the production of resource-saving equipment that does not harm the environment

Steel and cast iron heating batteries: which are better for an apartment?

Steel radiators are characterized by a democratic cost, however, they are not very popular in the heating equipment market. Consider the models that have proven themselves best in an apartment building with a DSP:

PURMO COMPACT 22 500. Finnish heating equipment has always been famous for its versatility. The steel radiator of this series is no exception. This model has a convenient wall mount, as well as a high maximum power (5572 watts). The area that this battery can heat reaches 50 m2.

Among other things, a steel structure of this type is light in weight and is the most convenient of all for self-installation in an apartment. It can be used in heating circuits with a pressure of no more than 10 atmospheres, which is a rather noticeable disadvantage.

KERMI FTV (FKV) 22 500. This model allows you to answer the question of which battery is better to put in an apartment with large rooms. It is a product of the German company KERMI. The main advantage of this type of steel radiator is that it has a high heat transfer coefficient. The panel design contributes to the heating of the living space. The power of such a device can reach 5790 watts.

The cost of cast-iron radiators is higher than that of their aluminum and steel counterparts, but much lower than bimetallic heating devices

Useful information! The area that this battery can heat is 57.9 m2. Therefore, it is perfectly suitable for installation in large rooms.

A steel radiator of this type is suitable for use in heating systems with a coolant temperature no higher than 110°C. Among the disadvantages of such a model, we can note a small indicator of the working pressure (10 atmospheres) and the poor quality of the enameled coating.

Cast-iron models have many disadvantages, but are still used in apartments. Among the variety of models made of this material, we can single out one that has a lot of positive reviews, namely: STI NOVA 500.

This radiator is the most popular among consumers. It is a product of an Italian company and has a good heat dissipation. This battery is perfect for small rooms (no more than 20 m2). The maximum temperature of the coolant that a structure of this type can withstand is 150 °C. Of the minuses, you can single out a large mass and considerable coolant consumption.

Steel radiators do not tolerate the ingress of oxygen inside, after several summers, even high-quality batteries can rust through

How to calculate the power of radiators and the number of sections?

The radiator should provide a normal temperature regime in the room. To do this, it is necessary to calculate the number of sections before purchasing it. Let’s look at some rules that will help to perform the corresponding calculation.

First of all, when calculating the power and number of sections of a heating device, it is necessary to focus on its dimensions. It is important to remember that the width of the battery should not be more than 70% of the window opening. To ensure normal heat transfer, the product is installed taking into account the central line of the window. The temperature norm of the radiator in the apartment affects the heating of the living space, so it is worth taking seriously the location of the device.

The distance from the working surface (wall) to the heating structure should not be lower than 3 and higher than 5 cm. And it is also worth considering the distance from the floor to the battery. It should not exceed 12 cm. In turn, the recommended distance to the window sill is 5 cm.

Often, to increase the efficiency of the device, the wall is covered with foil materials. Let’s consider what parameters will be required to carry out the correct calculation of radiator power:

• dimensions of the room;
• number of windows and doors;

Without the help of specialists and additional programs, it is quite difficult to calculate the number of sections of radiators

• the material from which the building is made;
• the location of the apartment.

Among other things, it is necessary to take into account the individual characteristics of the heating circuit.

Prices of heating batteries from different brands 

Today, the range of heating equipment is as wide as ever. But of the many different models, the most popular ones can be distinguished, which differ in adaptability to domestic operational features. An important factor when choosing a heating device is its cost. The price of batteries for heating should correspond to their quality.

Bimetallic devices are rightfully considered the most adapted to domestic conditions. Their cost depends on the company, as well as on the technical parameters. The price of the most popular bimetallic heater RIFAR MONOLIT 500 is about 5,500 rubles. Thus, for 5-6 thousand rubles. you can buy a good battery for your apartment.

Pay attention! The average cost of replacing a radiator in an apartment is 2000-3500 rubles. The total amount depends on the type of heating device and its installation features.

The cost of the radiator should not be a decisive factor for the purchase – an incorrectly selected battery, even very expensive, will not last long

Aluminum radiators are less expensive. You can purchase a device of this type for only 2500-4500 rubles. In turn, steel and cast iron models are the most expensive. For example, the most popular cast iron STI NOVA 500 battery costs about 7,500 rubles. The price of the most popular steel appliances ranges from 6-7 thousand rubles.

To choose a heating device for an apartment, it is necessary to take into account many nuances. But first of all, it is desirable to determine the financial capabilities and features of the DSP in your home. If necessary, you can seek advice from a specialist who will help you choose an effective device.
