How to choose room heating radiators. A warm house without problems: which radiators are better for heating an apartment. System characteristics and service life

Many people are forced to live in difficult climatic conditions. Not everyone can move to more acceptable regions, so most of the time has to be spent in well-heated rooms. This suggests that heating systems should be as efficient as possible, and special devices for them should be aesthetic! So which heating batteries are best for an apartment, what are their prices? You will find answers to these questions in our article.

What to look for when choosing radiators?

Modern heating appliances should be selected with extreme caution, as they must serve their owners for a long time and reliably. The main selection criteria are:

System type. Today, 4 types of radiators are especially popular, each of which has its own advantages and disadvantages. Cast iron models are distinguished by low cost, excellent thermal conductivity, durability and the ability to keep heat even after the heating is turned off. Among their disadvantages are slow heating, the need for frequent maintenance, fragility, consumption of large amounts of water and poor tolerance of water hammer. Aluminum systems have high heat dissipation, compactness, reasonable cost and light weight, but they are subject to corrosion. Steel radiators heat up quickly and are liked by customers for their low inertia and maximum heat transfer, and the most significant disadvantage of this type is the formation of rust. Bimetallic models are very demanding on water quality, but at the same time they are light in weight and are resistant to high pressure.

Price. Water heating devices are considered the cheapest, so when you purchase them, you can save a good amount of money. Foreign goods, of course, will cost more than domestic ones, but some of them will last much longer. Cast iron and aluminum radiators cost an average of 350 rubles per section, bimetallic - about 600 rubles per section, and steel in a complete set will cost 2-12 thousand rubles.

Heat dissipation. Non-sectional radiators (steel) have a total heat output of 1200 to 1600 watts. As for this criterion for one section, in cast iron it is 100-160 W, in aluminum - 82-212 W, and in bimetallic - 150-180 W.

4 Global STYLE PLUS 500

The best economical electric heaters of the new generation. Rating TOP 12.

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

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

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

A fairly common phenomenon that centralized communications are subject to is a violation of conservation. As a rule, this happens during the summer period. However, not all batteries are able to withstand the water hammer that occurs during such a depressurization in the system.

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

When replacing a heating device in an apartment, you should check the compatibility of the materials from which the batteries and connecting elements (fittings) are made. The incompatibility of metals leads to their oxidation, which often causes accidents in the DSP.

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 heating 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 operation in certain conditions. It is also worth saying that there are highly specialized models that are used to perform one function. This type includes floor-type convectors used in rooms that have a large glazing area. Their use eliminates the possibility of fogging windows.

On the market you can also find another type of convectors - plinth. They are installed in special metal boxes that replace classic skirting boards. The main advantage of such heaters is that they do not violate the overall interior of the room.

Today you can find a variety of batteries, in terms of design. The range of modern heating 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 an apartment

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 faded into the background. With the development of production technologies, more efficient and wear-resistant steel radiators have appeared, as well as appliances made from other materials.

Note! Cast iron material has a high coefficient of thermal conductivity. And also it is worth saying that it heats up for a long time, but at the same time it cools down just as long.

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

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

And also products made of cast iron are distinguished by their resistance to destructive corrosive effects. They are unpretentious regarding the quality of the working environment that moves through them. Long-term interaction of the inner surface of the battery, made of cast iron, with water leads to the formation of a dark precipitate, which has an antioxidant property. Therefore, with normal use of such radiators, they can 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 older cast iron batteries, new models do not require annual painting 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 release excess air.

In Soviet times, such radiators were manufactured in large quantities and had standard sizes. Today, the range of these devices offers customers almost 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 appliances. 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 conventional cast iron ones, 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. Consider what factors affect the choice of the number of sections:

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

Cast iron structures also differ in terms of filling volume. For example, in domestic radiators it is 1.3, and in foreign ones - 0.8 liters. The cost of the latter is approximately 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 the shortcomings

As mentioned above, cast iron radiators are no longer as popular as they used to be. This is due to their shortcomings. The main disadvantage of these products is their large weight, due to which their storage, transportation and installation are accompanied by certain difficulties.

Note! For fixing a standard cast-iron structure, it is necessary to use bulky fixing elements - brackets.

It is also worth mentioning that, in terms of design, standard cast iron products are not very 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 carry out operational regulation of the temperature regime in the room, and for autonomous heating systems this property is especially important.

Cast iron structures do not differ in strength characteristics and are especially susceptible to mechanical stress (impact). It is because of the above properties that these products are not in great demand in the modern market for heating equipment.

Varieties of steel radiators for an apartment

Steel radiators are one of the most popular today. They are distinguished by a mass of positive qualities, and are also quite presentable and fit 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 own advantages and disadvantages. In order to answer the question of which heating 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.

Which heating radiators are best for an apartment: steel panel batteries

The panel construction includes two steel sheets. By stamping, they are given the necessary shape. After that, the resulting blanks are joined by welding, which makes it possible to obtain a hollow panel. If necessary, it is supplemented by 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 emanating from the window.

After assembling such a radiator, it is painted. The protective coating is a very important element of the design, as it protects it from corrosion, makes it more presentable, and also helps to care for it. When choosing a new steel battery, special attention must be paid 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 temperatures of the working environment up to 95 ºC. They are designed for the standard pressure that is created inside the DSP, namely: 16 atmospheres.

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

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

Depending on where the heater will be docked with the pipe, there are two main options for steel devices:

• with bottom connection;
• with side connection.

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

Advantages and disadvantages of steel panel radiators

In order to answer the question of how to choose a heating 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, consider the positive qualities of these heaters.

The first and, perhaps, the most important advantage of the panel structure is the ease 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 design of the radiator 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 are easy to adjust to the desired temperature. And also such steel structures have a rather 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 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.

Like any other product, steel panel batteries have their drawbacks. The main one is that they are not designed for strong water hammer. They are reliable only at normal pressure indicators 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 gearbox. This device allows you to reduce the level of load on the panel during 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, these batteries include several sections. The fixation of these elements among themselves is carried out by welding. Such products do not require assembly, which is undoubtedly their plus.

Note! How to choose a tubular 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 ​​\u200b\u200bthe room that the sectional model will heat.

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, when using such models, to purchase a gearbox that is able to protect the tubular battery from water hammer.

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

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

These devices are available in various 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.

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 communications. However, they are not entirely suitable for use in DSP conditions, as they are susceptible to water hammer.

Selection of tubular batteries, depending on their design

Many apartment owners are interested in the question of which heating 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.

Mount such devices at different points of the dwelling. For example, the most common option is to install a tubular battery under the window, however, if desired, the location can be any. Often they are 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.

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

The presence of a wide range of shapes, a variety of colors and the presence of additional structural elements significantly expand the operational area of ​​such steel products.

Lamellar heating radiatorssteel (convectors)

The working medium in a lamellar radiator moves through 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 not 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 upward and can rise to a fairly significant height. If necessary, you can independently adjust the temperature regime in which such a heater will operate.

Plate batteries are able to withstand 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 this type is on average 6-9 thousand rubles.

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

The convector plates are very quickly contaminated with dust, which affects the heat transfer coefficient. Cleaning these elements is a rather difficult undertaking. 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 best for an apartment: an overview of aluminum models

Designs made of aluminum are distinguished by 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 harmful effects of corrosion. Given the low quality of the coolant, such a battery can fail after 5 years of operation.

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, due 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 construction used in DSP cannot boast of resistance to water hammer. Given this fact, it is worth saying that a radiator for this type of house is best suited for installation in autonomous heating conditions.

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 value of 5-6 units, which is a rarity in domestic DSPs.

Such heaters are lightweight, so 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 from a compatible material. Otherwise, areas affected by corrosion are formed at the docking points. Consider the materials that categorically cannot be used when mounting an aluminum battery:

• steel;

• brass;
• copper.

An ideal option for installing an aluminum radiator is a plastic heating circuit. In this case, the occurrence of corrosion is excluded, and the heating structure itself is simple for repair or dismantling.

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 control 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 ROYAL THERMO. Products from this brand are of good quality and reasonable cost. Such radiators are specially adapted for use in the CIS countries. They are characterized by good corrosion resistance and long service life (over 10 years).

Anodized aluminum batteries - ideal for an apartment

Aluminum heaters can be made with a special anti-corrosion coating called anodic. For the production of such batteries, a high-quality aluminum alloy is used, which undergoes preliminary cleaning, and a layer of oxidized anode is applied to the surface.

The technological process of manufacturing such products is quite complicated. During it, the structure of aluminum undergoes changes several times, which is a kind of hardening. Thus, the final product is characterized by increased resistance to corrosive effects 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, it is possible to repair the heating radiator in the apartment. Replacing a 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.

The inner walls of such models are smooth, which contributes to heat transfer. The coolant moves without any difficulty along the aluminum structure. 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 the 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 heating 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 it is worth noting the versatility. From the name it becomes clear that two metals are used in the production of such heating devices. Combined manufacturing can significantly improve the performance of these products.

The outer part of the bimetallic structure is usually made of aluminum. This allows you to achieve high rates of 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 corrosive effects.

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

The long service life of bimetallic heaters is determined by their structure. The aluminum shell does not come into contact with the working medium and acts as a kind of "case" for internal steel channels through which the coolant moves.

The steel part of the bimetallic radiator is highly resistant to the loads in the system. Such products are able to function at very high pressures (35-40 atmospheres). This makes them ideal for installation in apartments heated by DSP.

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

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

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

Batteries made of this material occupy the smallest segment in the heating appliance 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 produced from high-quality copper material that does not have 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 heaters made of this material is a high coefficient of inertia. They are able to quickly warm up, which contributes to efficient heat transfer. And also copper structures are distinguished 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.

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

It is also worth noting that such heaters do not need to be painted, as they have high anti-corrosion qualities. The service life of copper products exceeds 10 years. They have a presentable appearance and thanks to this they can become an adornment 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 heating radiators for an apartmentfrom different materials

Vertical radiators have several advantages over appliances that are mounted in a standard way. They are lightweight, versatile and easy to install. Tall batteries are a great solution if there is not enough free wall space to install a conventional device. Vertical models are made from different materials:

Cast iron. High heaters made of this material are quite unpretentious. For them, the quality of the coolant does not matter. 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 minuses of such high batteries, one can note - a large mass, which makes their installation difficult.

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 steel radiators are susceptible to water hammer and are most often used in private houses equipped with an autonomous heating circuit.

High heaters are distinguished by their efficiency and aesthetics. You can buy a vertical heating radiator for an apartment in any specialized store or place an order via the Internet. 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 space heating due to their dimensions. The temperature of the working medium in such radiators ranges from 60 to 70 °C. They are able to provide a standard temperature regime in the room (from 20 to 24 ° C). Aluminum vertical radiators are lightweight and have the ability to add sections. Such products are most often used in autonomous heating circuits.

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

Whatbuy a heating batteryfor an apartment: the main selection criteria

Before buying a heater for an apartment, you need to pay attention to a few key points. There are certain criteria, the study of which will allow you to answer the question of how to choose a radiator. Heating batteries must meet all the necessary technical specifications, have a passport and instructions.

Consider the main factors by which it is necessary to select a battery for an apartment.

Operating pressure. The operating pressure must be indicated in the documentation for the heater. Experts recommend purchasing batteries with a certain margin. The operating pressure of the battery must exceed the same indicator in the central heating circuit by approximately 1.5 times. This will allow you to play it safe, since pressure surges often occur in the DSP.

Note! In five-story old-style buildings, the pressure in the heating circuit is about 6-8, and in modern high-rise buildings - 10-15 atmospheres.

Resistant 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 act on 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.

Number of sections. If, when choosing a heater, there were difficulties in determining the required number of sections, then it is recommended to pay attention to models that can be “built up” if necessary.

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

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

The composition of the coolant. You should also not forget that the battery life is also affected 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.

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.

Ease of installation. Such a criterion is not among the necessary ones. However, if you decide to install the heating structure yourself, then you should select products that are lightweight. And also to study the options for fasteners and the features of connecting a particular model to the heating circuit.

Which heating batteries are best for an apartment: professional advice

So what kind of heating radiators is better to put in an apartment? Experts recommend that you consult with a plumber before purchasing a heater. In any case, you will need to find out the features of the DSP and coolant, including:

• pressure in the heating circuit;
• Ph working environment;
• Heat carrier temperature.

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

Useful information! For residential buildings that have more than 12 floors, a bimetallic battery would be an excellent option. Also in this case, cast iron models can be used. If the working pressure index does not exceed 14 atmospheres, and the Ph index 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 DSPs, the pressure in which exceeds 20 atmospheres.

Rating of heating radiators for an apartmentbimetal

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

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

The number of sections for such batteries varies from 4 to 12. Also, bimetallic radiators of this model are of high quality painting and aesthetics. Of the minuses, one can note increased sensitivity to the working environment.

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

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

RIFAR MONOLIT 500. The most popular bimetallic radiator, which is highly resistant to water hammer and has a working pressure of as much as 100 atmospheres. The Rifar company is located in Russia and specializes in the production of heating appliances adapted to domestic conditions of use.

Such a model may 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 required 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 minuses of this radiator, weak sound insulation can be distinguished.

Which heating radiators are best for an apartment: pricesand characteristics of aluminum models

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

TERMAL 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 working pressure for the RAP-500 model is 24 atmospheres, which exceeds the standard values ​​in the DSP.

Note! When buying an aluminum heating device, it is imperative 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 TERMAL brand can withstand is 130 ° C.

RIFAR ALUM 500. Such aluminum batteries, as in the previous case, are produced 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 aluminum model from this manufacturer can withstand pressures up to 20 atmospheres and is resistant to minor hydraulic shocks in the DSP. Its service life can reach 25 years under normal use. The main disadvantage of this model is a low-quality protective coating.

ROYAL THERMO REVOLUTION 500. 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 conditions for rooms with an area of ​​​​up to 40 m². This model is suitable for use in DSPs, the working pressure of which does not exceed 20 atmospheres. Thus, we can conclude which heating radiator is best for an apartment. The price and photo of such a battery can be easily specified on the Internet.

Of the minuses of this heating equipment, one can single out the fact 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.

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

Steel radiators are affordable, however, they are not very popular in the heating equipment market. Consider the models that have proven themselves best in an apartment building with 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 is capable of heating reaches 50 m².

Among other things, this type of steel structure is lightweight and is the most convenient of all for self-installation in an apartment. It can be used in heating circuits with a pressure not exceeding 10 atmospheres, which is a rather tangible disadvantage.

KERMI FTV (FKV) 22 500. This model allows you to answer the question of which battery is better to install 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.

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

A steel radiator of this type is suitable for use in heating systems with a coolant temperature not higher than 110°C. Of the minuses of such a model, one can note a small indicator of working pressure (10 atmospheres) and the low quality of the enamel coating.

Cast iron models have many disadvantages, but are still used in apartments. Among the whole variety of models from this material, one can be distinguished, which has many positive reviews, namely: STI NOVA 500.

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

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

The radiator must provide a normal temperature 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 you perform the appropriate calculation.

First of all, when calculating the power and number of sections of the heater, 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 center line of the window. The temperature norm of the heating radiator in the apartment affects the heating of the living space, so you should take the location of the device seriously.

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 windowsill is 5 cm.

Often, to increase the efficiency of the device, the wall is covered with foil materials. Consider what parameters will be required to correctly calculate the power of the radiator:

• room dimensions;
• number of windows and doors;

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

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

Heating battery pricesfrom different brands

Today, the range of heating equipment is wider than ever. But from 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 technical parameters. The price of the most popular bimetallic heater RIFAR MONOLIT 500 is about 5500 rubles. Thus, for 5-6 thousand rubles. you can buy a good battery for your apartment.

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

Aluminum radiators are less expensive. You can buy 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 STI NOVA 500 cast iron battery costs about 7,500 rubles. The price of the most popular steel appliances ranges from 6-7 thousand rubles.

When choosing 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.

The question of choosing a suitable radiator for heating a house or apartment plays an important role. After all, safety, the possibility of saving on energy resources, compliance with interior design, warmth, and hence the feeling of comfort in housing depend on this. To answer the question, for central heating, you first need to establish the technical characteristics and features of each type of modern batteries.

Choosing a heating radiator is necessary considering many factors.

When purchasing a radiator, the following aspects are of no small importance:

• Efficiency of functioning, that is, the ability to heat the room.
• Safety and durability.
• Availability in terms of price.

Also, the choice of heating radiators is largely determined by the system in which they will be installed - central or autonomous.

The centralized system used in apartment buildings has the following features:

1. Typically, the operating pressure in this system when supplied is in the region of 4-5 kgf / cm 2 and slightly less at the outlet. In private homes, the maximum pressure is only 2 kgf / cm 2.
2. In central systems, the probability of unforeseen circumstances associated with water hammer, the use of heat carriers with a temperature above the permissible level, etc. is much higher.

The technical characteristics of the heating system, which are determined by:

• Working pressure.
  The basic rule: the pressure of heating batteries is greater than in the room in which they are installed. Otherwise, a leak will soon appear. The technical characteristics of the heating system, which are determined by:
• The type of heating system is one- or two-pipe.
• Radiator power. The most important value, which indicates the efficiency of heat transfer from the source to the consumer, that is, how well the radiator heats the house. The power indicator is influenced by the presence of windows and the material from which they are made (wood or plastic), the type of house (panel or brick), the number of external walls, and the area of ​​\u200b\u200bthe room. The value required is determined by multiplying the area of ​​​​the room by 100 W and increases by a certain percentage depending on various factors:
  • in the presence of 2 external walls and 2 windows - by 30%;
  • when the windows go to the north side - by 10%.

• Radiator sizes. The device must correspond in size to the place intended for installation. The optimal distance between the window and the radiator is from 10 cm or more, the floor and the radiator - from 6 cm. The width of the radiator should exceed 50% of the width of the window under which it is installed.

The main types of radiators have the following characteristics:

Also, do not forget about such nuances as the presence of a thermostat, pipe diameter, window width.

The main types of radiators for central heating, their disadvantages and advantages

Cast iron radiators. The leading type of radiators in terms of prevalence for several decades. Only the appearance has changed significantly - there are models that are real design samples (their cost is appropriate). Good for use in residential and industrial high-rise buildings.

Advantages:

• high heat transfer;
• strength and durability;
• unpretentiousness and endurance;
• large flow area, allowing you to maintain the throughput even with the accumulation of deposits.

Flaws:

• the need for washing 2-3 times a year;
• vulnerability to strong mechanical stress (the battery may crack);
• high price.

aluminum radiators. Currently enjoys great popularity among Russians. They consist of sections, the number of which depends on the area of ​​\u200b\u200bthe heated room. It is this type that is characterized by the highest degree of heating, achieved due to the high thermal conductivity of the metal itself and an increase in the area of ​​\u200b\u200bthermal conductivity, thanks to the developed finning system. According to the design, sectional and solid models are distinguished.

Aluminum radiators are not recommended for centralized heating systems. Since, in the presence of oxygen in the coolant, this metal is oxidized, and the sections are “aired” due to the release of hydrogen. To avoid this, the device requires regular maintenance and evacuation of air.

Advantages:

• ease;
• external attractiveness;
• strength and reliability;
• excellent heat dissipation.

Flaws:

• susceptibility to corrosion;
• the need to regularly bleed air from the radiator through the air vent valve;
• deformation of aluminum during water hammer;
• solid particles present in coolants contribute to the destruction of the walls of the device from the inside, which reduces the life of the device (this problem is solved by equipping the radiator with mud collectors and additional filters that require regular cleaning);
• when connecting aluminum pipes with copper, the rapid destruction of aluminum.

Steel radiators. A common view in the conditions of low-rise private construction. Not the best option for centralized heating, because:

• usually the working pressure in the heating system exceeds the allowable one;
• with hydraulic shock, the service life is significantly reduced and is only a few months.

Advantages:

• attractive design;
• occupation of a small space in the room.

Flaws:

• susceptibility to corrosion;
• average service life at observance of operational rules - no more than 7 years.

Bimetal radiators. They combine the advantages of the two previous types of radiators, due to the special design - an aluminum shell and a steel core. They are used for any type of heating, but they have proven themselves especially well in high-rise buildings with central heating.

Advantages:

• the ability to withstand significant loads and hydraulic shocks, strength;
• high heat transfer;
• light weight and thoughtful shape, contributing to the efficient heating of the room.

Flaws:

• high price due to the complexity of the design.

conclusions

So, it is not possible to give an unambiguous answer to the question of which heating radiators are best for central heating, since each specific situation is individual and the choice depends on the characteristics of living conditions and the price range. But in general, the opinions of experts boil down to the following:

1. Due to the unpredictability of central heating, those that combine mechanical strength, high heat transfer and aesthetic appearance are currently considered the best. The main disadvantage is the high cost.
2. Cast iron radiators also deserve attention, but require more maintenance.
3. It is better to refuse steel and aluminum radiators in houses with central heating, due to the characteristics of these metals - susceptibility to corrosion, interaction with other metals, etc.

The radiator is an important part of the home heating system. Its thermal conductivity and aesthetics affect the appearance of the room and comfort. Price is also an important factor. This is especially true for apartments. We will try to tell you in this article how to make the right choice of a heating radiator for an apartment.

Heating system and radiator compatibility

There is a wide range of heating radiators on the market:

• steel;
• aluminum;
• cast iron;
• Copper;
• Bimetallic devices.

The choice of a particular radiator depends on various parameters of the entire heating system. The allowable temperature, pressure in the system and the composition of the coolant are taken into account, as well as heat transfer and inertness, which must correspond to the indicators of the heating system of an apartment building.

Important! Heating radiators for open systems of apartment buildings differ from those designed for closed heating systems of private (individual) houses. If the radiator does not match your heating system, not only rapid wear is possible, but also a complete failure of the radiator.

How to choose a radiator?

First of all, when buying a battery, you should pay attention to its technical and operational characteristics, and only then to the cost or appearance.

Regardless of the country of manufacture, it must be clearly understood that not every battery can withstand the operating conditions of our heating networks: fluctuations in pressure and temperature, poor quality of water supplied to the pipes (coolant) and others. For example, in high-rise buildings for a single-pipe open heating system, the design temperature is 105 ° C, and the pressure is 10 atmospheres. But, despite this, the limits of these parameters can go off scale, and heating radiators of foreign manufacturers that do not have the necessary margin of safety may simply not withstand a water hammer.

Note! Before buying a radiator, it is necessary to take into account the allowable temperature and pressure of the coolant in the heating system. These data are indicated in the passport of the heating device.

The heat transfer of the heating battery is also important. The efficiency of air heating depends on this indicator, which is also determined by the design of the radiator. For example, the heat transfer of aluminum is higher than that of steel, and copper gives off heat better than cast iron. However, relying only on these technical parameters is also not entirely correct. It is necessary to comprehensively evaluate all the advantages and disadvantages of each element of the heating system before buying the best heating radiators for the apartment in which you live.

Heating radiator options

Consider the most common types of heating batteries on the market

Cast iron radiators

Cast iron batteries have been used in domestic heating systems for over a hundred years. They have shown excellent resistance to corrosion, are sufficiently durable, have good heat dissipation and are able to withstand pressure and temperature drops in the system. Almost ideal option for operation in the territory of the countries of the former USSR.

Cast iron radiators are able to retain heat for a long time, even after an emergency shutdown of the system. These batteries withstand both poor water quality in the system and water hammer. They are not affected by rust or air pockets, compared to appliances made from other materials. All these advantages make cast-iron radiators an ideal option for a heating battery for an apartment.

The disadvantages of cast-iron radiators include high inertia, unsightly design and bulkiness. The inertia makes these batteries unsuitable for heating systems with thermoregulation.

The exception is modern models in retro style, with monograms, patinated, painted to look like copper, bronze or brass, which fit perfectly into the interior, being both a heating device and an art object.

Aluminum radiators

Sectional radiators made of aluminum are very popular today. Light weight, aesthetic appearance, high heat dissipation, these batteries are good for arranging heating systems in apartments and houses.

Thanks to the sections, you can dial any length of the radiator, and ease of installation is another indisputable plus. This type of batteries is not inertial, which makes it possible to install them in systems with temperature controllers. In addition, a large amount of coolant (water) is not required.

A significant disadvantage of aluminum batteries, experts consider susceptibility to corrosion at high concentrations of alkali in water, as well as a tendency to form air bubbles inside the structure and the risk of leakage between sections.

Steel radiators

In the heating systems of houses and offices, you can often find batteries made of steel. They may look different:

• Type-setting panel from separate sections;
• One-piece rectangular construction;
• tubular construction.

The advantages of steel batteries are in an affordable price, inertia, attractive appearance, excellent heat dissipation and corrosion resistance.

However, steel batteries are not capable of withstanding water hammer in excess of 25 atmospheres, which makes them unacceptable for use in high-rise apartment buildings. In addition, steel is quite sensitive to the presence of oxygen in the coolant.

The optimal pressure for the normal operation of steel batteries ranges from 6 to 16 atmospheres and depends on the thickness of the steel and the design of the device. The operating temperature must not exceed 110°C. Heat transfer is carried out by convection and radiation through the walls of the device and the grate located in the upper part of the radiator.

Bimetallic radiators

Bimetal radiator consists of aluminum fins and steel piping. This type of battery is optimally suited for operation with our city district heating networks. In this design, hot water circulates through seamless steel pipes, welded together by a method that prevents corrosion and destruction of the metal. And aluminum, in turn, due to its high thermal conductivity, perfectly transfers heat from the core to the room.

The radiator is able to withstand pressure in the system up to 40-50 atmospheres. Modern designs have a fairly attractive appearance. Thus, in a bimetallic radiator, the properties of steel and aluminum are combined in the best way as heating devices.

Among the advantages, one can also point out that bimetallic batteries contribute to the turbulent distribution of air masses (with eddies). Thus, there is no local overheating of the air, the formation of a positive ionization field in the heater zone. Bimetallic heaters can serve for about 20 years and come to the retail network already painted, which simplifies their maintenance.

The disadvantages of bimetallic heating devices include their rather high cost, as well as the tendency to accumulate slag deposits along the inner walls over time and sensitivity to the presence of oxygen in the coolant. They also distinguish the resistance that occurs at the interface between the two metals, which reduces the efficiency of heat transfer as a whole.

Copper radiators

Copper heating radiators are made of seamless copper pipe. The design consists of a pipe with a diameter of about 28 mm, complemented by copper fins and a wooden casing. The efficiency of air heating is achieved due to the high thermal conductivity of copper, which is 2 times higher than that of aluminum and 5-6 times higher than that of steel and cast iron. Copper has a low inertia and can be used in systems equipped with thermostats.

Despite the fact that copper batteries require less coolant, they heat up in 3 minutes. In this case, there is no need to drive large masses of hot water through copper batteries (for example, as is the case with cast iron appliances).

The advantages of copper are undeniable:

• Corrosion resistance;
• Plastic;
• It is not subject to wear when exposed to an aggressive environment;
• Plastic;
• High efficiency at low coolant temperature;
• Suitable for installation in apartments of multi-storey buildings.

Interesting! After the first 90 hours of operation of copper radiators, an oxide layer forms on the inner surface, which subsequently protects the battery from mechanical and chemical damage from poor quality hot water.

Almost the only drawback is the high price of copper heating appliances.

Calculation of the power of heating radiators for an apartment

For a normal microclimate in a living room, the heating radiator should not overlap 70-75% of the width of the window opening. Then the cold air from the window and the warm air from the battery mix freely and move around the room, without fogging the windows. Therefore, instead of 5-6 powerful sections, it is better to put 8-10 sections with less power, but occupying the required area under the window.

To find out the required power of the radiator, it is necessary to multiply the area of ​​\u200b\u200bthe room by 100 watts. If a:

• If the room has 1 window or outside door and 2 outside walls, then the battery power is increased by 20%;
• 2 windows and 2 external walls - by 30%;
• The window faces north or northeast - by 10%;
• Battery in a niche - by 5%;
• The radiator is closed by a panel with slots - by 15%.
