How to find out what heating radiators are. What heating batteries are best for an apartment: classification of radiators and their features. Resistant to high pressure and water hammer

Reading time ≈ 8 minutes

If you want to determine which heating battery is best for an apartment, then first of all, you should not discount the difference in the source of the coolant, that is, it can be both centralized and autonomous. For the effect of heating the room, there is practically no difference here, but the pressure in the circuit is different, therefore, the source material from which the device is made must be of appropriate strength. But when choosing a radiator made of any metal or alloy, there are also some nuances that will have to be taken into account.

Difference in pressure of centralized and autonomous heating systems

Differential pressure in the system with centralized heating

In order to choose heating radiators for an apartment in a multi-storey building, you will have to take into account the possible operating and pressure test pressure in the system. First of all, you should consider the load on the circuits when connected to centralized boiler houses or CHP plants. In this case, we are not interested in static (gauge) or dynamic pressure - we will leave this for the designers.

The following factors influence the pressure in the system:

• power of equipment (pumps) supplying water to the consumer;
• diameter of risers and loungers in the system;
• the height of the apartment in the building (number of storeys);
• pipeline wear (occurrence of emergency situations).

Taking into account all the factors listed above, the working pressure can be:

• 1-5 floor - 2-4 atm;
• 6-9 floor - 5-7 atm;
• 10th floor and above - 12 atm.

To detect defects and prevent breakthroughs from water hammer at start-up, a pressure test is used, which exceeds the operating pressure by 0.5-1.5 times, that is, such a check provides for a load of up to 15 atmospheres, which not every radiator can withstand.

In autonomous heating systems, this issue is most often not even considered, since the pressure there does not exceed 1-3 atmospheres, and when this threshold rises, a safety valve is triggered on the boiler. There are, of course, some brands of boilers where the heat exchanger is able to withstand up to 7 atmospheres, but this is already the safety margin of the unit, and not the need for the circuit, therefore the valve will work already at 4 atmospheres or not reaching this mark.

Radiator selection

All heating devices can be divided not only by the source material of manufacture, but also by their design. They are mainly divided into four types:

1. Sectional - they are also called columnar, since the vertically arranged sections resemble columns. Devices of this type are prefabricated structures, therefore, to change the power, the required number of sections can be added or removed.
2. Tubular - are two horizontal pipes Ø50-75 mm, connected by vertical pipes of a smaller diameter. They are used only for district heating.
3. Panel - made mainly of metal, although there are concrete options. The capacity depends on the volume of the tank.
4. Lamellar - designed as an economical option for materials. They are a horizontal pipe with plates welded onto it, which contributes to convection heat transfer.

Heating radiators - which are better

Differences in materials

Consider a number of options, taking into account the source materials. That is, the choice of heating devices depends on these parameters; they may or may not be suitable simply for technical or aesthetic characteristics.

Aluminum heating appliances

Aluminum radiators of different sizes and power

There is a lot of talk about aluminum radiators, as about some kind of know-how or just some kind of superstructure that can provide the most maximum heat transfer and energy savings for the boiler. In fact, this is far from the case, or more precisely, it does not correspond to reality at all. The only truth here is that aluminum has very good heat transfer and ... Yes, that's all! It is precisely in heat transfer that the artificially created excitement around aluminum lies, in addition, this metal has more critical drawbacks.

Firstly, this is a small resistance to pressure and, in order not to go into calculations, let's say that they are suitable exclusively for autonomous heating, where the working pressure does not exceed 2-3 atmospheres. In addition, aluminum itself is a rather "delicate" metal and water with its salts and alkalis will destroy it. Therefore, the use of aluminum depends entirely on the quality of the coolant, which is possible only in the private sector or.

More precisely, drugs such as antifreeze have to be added to the water (more on this separately). Not a single centralized boiler house in the world has yet provided the proper conditions for aluminum radiators!

Copper heating appliances

Copper heaters made according to the Buleryan principle

It would be wrong to keep silent about copper heaters made on the principle of a convector or "Buleryan" - these are, perhaps, the best devices, if we proceed from the principle of heat transfer, although they are used extremely rarely. Of course, this is not so surprising, since copper is the most expensive of non-ferrous metals (precious ones are not taken into account). Plate radiators and those made according to the "Buleryan" principle behave best here, although I did not mention them in the "Choice of Radiators" header, but this is not so important.

Note. Most often, such devices are made in the form of plate structures - they are much cheaper, but less effective. The Buleryan system has the highest heat transfer possible at the moment!

Of course, copper is stronger than aluminum and can be used in high-rise buildings, it is very effective, beautiful and convenient, but ... too expensive. Firstly, if you need to find out which heating battery is better for an apartment, then first of all you are interested in heat transfer and pressure resistance, that is, the operating resource. Secondly, you ask how much it costs and the second question will most often be fatal ... You will politely refuse and buy another heating device, especially since they are more suitable for autonomous heating.

Cast iron radiators

Cast iron radiators are known to all people

Finally, we have come to such familiar and familiar cast-iron radiators, which are familiar to any tenant of an apartment in a multi-storey building, only, I want to warn you - do not consider them as "crap" - this is not something that a delusion, but an elementary technical illiteracy. First of all, cast iron is one of the metals that are least susceptible to corrosion, and this is very convenient in high-rise buildings, since when the coolant is drained, you can not be afraid of rusting. In addition, cast iron itself is a weak heat-conducting material, that is, it heats up for a long time, but it cools down for a long time. It was this factor that became the decisive argument when choosing heaters for the apartments of Soviet citizens!

But that's not all - cast iron is able to withstand operating pressure up to 16 MPa (maximum pressure test or water hammer), and also maintain temperature (this has already been mentioned, but this is not superfluous). Perhaps someone will not be satisfied with the appearance of a cast iron battery, but do not forget that this is one of the most efficient for district heating systems! For stand-alone structures, cast iron is unacceptable due to the duration of heating of the sections.

Steel radiators

Panel-type steel radiators

First of all, we can mention that the technical characteristics of steel heating appliances are no worse (and even better) than those of cast-iron radiators, but the problem is that ordinary black steel is subject to corrosion. It makes no sense to understand the characteristics of the materials - this is not a topic, just a steel battery will not last long, although it does not care about any pressure drops. Such devices can be of any configuration listed in the section "Selecting heatsinks".

Note. From personal practice. A steel radiator of 6 sections leaked for the 5th year of operation. A rusted rib on the bottom - I first sealed it up with dry welding, and at the end of the heating season I just took it off and threw it away.

Bimetallic radiators

Bimetal radiators of different sizes

Now let's talk about the best household heating appliances - about, which withstand the highest pressure and temperatures in the heating circuit and at the same time have the highest service life. So, the walls of such a device are made of two metals - steel and aluminum, therefore, one element is responsible for the maximum strength of the heater (steel), and the other for the maximum heat transfer efficiency (aluminum). Such a tandem can be called the most successful option of all devices for centralized or autonomous heating systems of radiator circuits.

Features of the choice of radiators

Conclusion

Perhaps you will not dispute the question of which heating batteries are better for an apartment, if the answer suggests itself - bimetallic. But do not rush to buy and first understand the classification of such devices - research is never superfluous!

When performing repair work, people are often faced with the task of replacing old batteries with modern, highly efficient counterparts. Naturally, the question arises - how is it right choose the most efficient heating radiators which ones are best installed in the apartment. The answer will depend on many components, the main of which are the area of ​​the future heating, the type of the intended device, the conditions of its operation, etc. Nowadays, the building materials market offers a wide range of heaters made from different raw materials and for different needs.

District heating system: main characteristics

For apartment radiators special requirements are imposed, since they will become part of the district heating system, which has its own specifics of work. All such systems have similar operating conditions - the heat carrier is supplied by heating mains from the CHP or boiler house to a multi-storey building, where, using a pump and other equipment, it is distributed through internal pipelines that deliver it directly to the dwelling.

The centralized heat supply system has its own underwater rocks and significant disadvantages:

1. Fluctuation of temperature indicators (either rapid heating, then cooling);
2. Possibility of sudden pressure drops - water hammer;
3. Low coefficient of heat transfer to the batteries, as a result, insufficient heating of the premises and the uneven temperature of the latter (some are hot, others are cooler);
4. Seasonal drainage of the coolant from the system;
5. Poor water quality - presence of aggressive components, oxygen, sludge, hardness, acidity, etc.

All of the above, over time, leads to increased equipment wear. And in a situation where a water hammer occurs, the connections themselves batteries may leak or burst altogether, having brought a lot of trouble. Also, due to the not ideal coolant, which can, during circulation, carry plaque, particles of rust, lime and other debris, the channels and pipes of the radiators are clogged. This will result in shortage of paid heating resource, as well as increased corrosive reactions inside the heaters, which significantly reduces their shelf life.

Important! To minimize all the listed risks, you need to correctly select heating devices.

Selection options

The main point at which worth paying attention, when selecting radiators is material from which they are made. Different alloys will behave differently under the same operating conditions. At the moment, the market is ready to offer four main types of heating technology:

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

For each type of heater, the manufacturer prescribes its technical characteristics:

• operating pressure;
• maximum allowable pressure;
• design feature (sectional, tubular or panel);
• water volume;
• recommended hardness and temperature of the coolant;
• warranty period of the device.

Most of the products manufactured on the market made according to the requirements of the EU states, the quality of heating networks, which is many times superior to domestic ones. Therefore, be sure to consider this fact when buying. For example, the pressure indicator in our centralized heating systems is 11-16 atmospheres for high-rise buildings and 5-10 atmospheres in standard 5-storey Khrushchev buildings. The operating temperature of the supplied liquid ranges from 65-90 ° C. Choosing heating technology, based on these data, You will protect yourself from possible emergencies.

Video. Which radiators to choose

The main products on the market can be roughly divided into several of the most popular categories:

Aluminum

This type of battery is primarily has a beautiful aesthetic appearance, correct and ergonomic shape, as well as excellent technical characteristics. They are quite compact and can be sold in separate typesetting sections. This is very convenient, since having made the correct calculations, you can choose the size that will optimally heat your room... Aluminum radiators are available in different heights and can be placed in any convenient corner of the room. Standard operating pressure at which the heater is most efficiently gives off heat, is 6-12 atmospheres, the maximum allowable, with sharp jumps up to 25 atmospheres.

The advantages of such equipment include:

• Great modern design;
• The increased heat transfer coefficient, depending on the wall thickness, can be up to 200 W per one section of a standard size;
• Low weight of the devices, which simplifies their installation, even with your own hands;
• By means of a set of elements, you can select the required size that meets your requirements;
• Excellent powder coating that resists damage.

The main minus of similar batteries, according to consumer reviews, is their possibility of long-term operation only in closed-loop systems, with strict monitoring of the level of hardness of the coolant. Such networks must be made from the same material as the radiators, since aluminum, in contact with brass and copper parts, can start electrochemical reaction processes... Modern systems are recommended to be implemented using plastic pipes, and the heaters themselves are reliably grounded.

Important! Another phenomenon inherent in aluminum batteries ispossible unpleasant sounds ... They can appear later in the interaction of the metal with a liquid abundantly saturated with oxygen, as a result of which hydrogen is released. Because of this feature, everyone is recommendedequip the radiator with a Mayevsky crane.

Taking into account all of the above, we can say that heaters made made of aluminum, despite a number of positive properties, in city apartments better not to mount.

Video. What is the difference between aluminum radiators and bimetallic

Bimetallic

This type of equipment is made from an alloy of two metals - soft aluminum and hard steel. The design of such batteries assumes that their inner part, which is in contact with the coolant, made of steel, and the outer one from aluminum... it one-stop solution allows the use of this type of heaters in systems with any (within reasonable) pressure and with different types of connections and main pipes.

The advantages of such products:

• Increased wear resistance and resistance to corrosive reactions, with any composition of the coolant;
• Allowable pressure up to 35 atm .;
• Good external data;
• Light weight and ease of fastening;
• Weak inertia - increased heating capacity, have excellent heat transfer rates;
• Equipped with taps for adjusting the intensity of the heat carrier supply;
• Type-setting type of construction, allowing you to select the device of the required configuration.

Essential there are no shortcomings of such products, perhaps a higher cost compared to competitors. But it is justified, first of all, by reliability and a longer service life. This type of radiator is most popular takes leading positions in most ratings dedicated to heating devices.

Important! When installing similar products,you must follow the instructions from the manufacturer, as well as adhere to the technical distances from the wall, window sill and floor - at least 4 cm.

Cast iron

Good old cast iron is known to almost every inhabitant of our country, due to its widespread use in the former USSR. Times change, and bulky, standard shape and painted with ordinary paint, batteries are a thing of the past... In their place are modern counterparts made from the same cast iron, but made using other technologies, according to new aesthetic requirements.

Cast iron batteries

Advantages of heating devices made of cast iron:

• Operated in any heating systems, with all types of pipe products;
• They can work for a long time in centralized heat supply networks, with a low quality of the coolant, the pH of which is in the maximum permissible range of 7-9;
• Working pressure of products is 7-10 atmospheres, maximum 18 atmospheres;
• They have a sectional typesetting design, which allows you to change the size to fit your needs.

Cast iron heaters have a number of indisputable advantages and unique qualities... The main thing is that they practically do not corrode. This is due to the fact that upon initial contact with water, a thin layer of insoluble black precipitate forms on the alloy, which serves as an obstacle to the ingress of active oxygen contained in the water to the metal. The destruction of the structure of cast-iron elements from the inside, of course, occurs, but extremely slowly. From the outside, they are coated with a modern powder paint, specially designed to withstand large temperature changes. In such batteries, gassing processes are insignificant, due to which there is no bubbling and there is no need for constant bleeding of air masses.

Against the background of all the positive aspects, there are also negative ones - these are huge weight leading to installation difficulties, and high inertia. Due to the latter, the heating of cast iron is rather slow, as well as cooling, therefore, a quick adjustment of the temperature of a room equipped with such heaters is impossible.

Steel or tubular

Batteries made from this material are universal and budget solution equip the heating system in a modern way. They are presented in the form of two plates, inside which the heat carrier passes in the steel pipes of the welded circuit. Radiators of this type have different sizes and a ribbed surface that provides excellent convection qualities and increased heat transfer. The metal has the same coefficient of thermal conductivity as cast iron, however, with some difference - its thickness is several times less than that of cast iron products. Due to this, their warming up is much faster. This type of radiator is designed for operation at an operating pressure of up to 10 atmospheres.

The advantages of steel products:

• Variety of shapes and modern design, allow you to place such batteries in any interior;
• Long period of operation, subject to proper water treatment;
• They are used in systems with any kind of pipes;
• Relatively low cost and ease of installation.

An important nuance before buying steel radiators is their correct and competent calculation, in view of the fact that they are implemented in certain standard sizes and they will not work out as sectional ones.

Also, it should be noted that in conditions of prohibitively high pressure surges, steel panels, can depressurize and leak... Therefore, it is not recommended to use them in buildings with more than five floors.

Tubular radiators are a kind of steel batteries, only they differ from panel radiators in a special design. They come in a variety of shapes and designs. All of the above characteristics of steel products are inherent in them.

How to calculate

There are certain norms by which you can calculate compensation for heat loss premises and, accordingly, find out the required thermal power of the devices in order to compensate for losses and create comfortable conditions for a person.

For the calculation itself, you can use the following formula:

K = S * 100 / Pc,

where K is the number of sections, S is the estimated area of ​​heated square meters, Pc is the heat transfer power of one battery section (this value is indicated by the manufacturer in the product passport). Such the calculation is applicable for aluminum, bimetallic and cast iron heating devices.

For steel non-separable steel-type radiators, it is customary to take the power value from the passport. The heater is selected at the rate of 100W per 1 m2. That is, if the area of ​​the room is, for example, 20 m2, then you will need a 2kW radiator, or two 1kW panels.

Counting the number of sections

Electrical

Sometimes the use of centralized heating is impossible for a number of reasons - it can be a breakthrough of the heating main, economic disadvantage, etc. In such a situation, many consumers pay attention to electric batteries... And not without reason, they have a lot of advantages- they are easy to operate, economical, perfectly amenable to adjustment, both mechanical and remote, and also have an acceptable cost. In many Western European countries, residents have long moved away from central heating systems in favor of individual electric heating networks. Today the market is represented by variety of heating devices using electricity, the most popular of which are fan heaters, oil and infrared radiators, and convectors.

Outcomes

Choosing new batteries for an apartment, don't save too much, since this in the future may result in big trouble, in the form of a flood. Therefore, to the problem of the selection of heating equipment of this type, come up responsibly, collect all the necessary information, consult with experts. Buy products only from well-known and proven brands that can reliably provide you and your loved ones with warmth.

Video. 10 mistakes when replacing radiators

A warm and cozy apartment is the best reward in winter. In many ways, the quality of heating depends on the heating radiators installed in the apartment.

When choosing the right equipment, you need to take into account many nuances and technical characteristics. Which radiators are best for heating an apartment? To answer this question, it is necessary to consider in detail all the existing types of batteries.

Varieties of apartment radiators

Classification by design

For an apartment, the best batteries are type-setting sectional radiators. The panels often do not withstand high pressure in the central heating system, and the lack of a beautiful appearance of the tube-type battery does not allow its installation in the room.

Classification by material used

To find the right heater, you should consider the technical characteristics of all radiators offered by manufacturers:

Classification by the cost of devices will also help to select batteries for heating an apartment. The budget versions include cast iron and aluminum, steel and bimetallic products have an average price category. The most expensive are copper heaters and stainless steel models.

The cost of replacing heating batteries in an apartment directly depends on the cost and quality of heating devices.

What heating radiators are better to put in an apartment

Replacing heating batteries in your apartment can be a serious investment. Low-cost versions of radiators are mainly intended for connection to systems with a pressure of less than 7 atm.

How to choose a heating battery for an apartment

• Performance... You do not need to calculate the battery power for an apartment. When replacing radiators, it is required to install a completely identical heating device with respect to heat output. Any performance gains are illegal. The calculation of the number of radiators is carried out in a similar way.
• Maximum pressure- the optimal indicator is 15 atm. This pressure ensures that the device is able to withstand water hammer.
• Coolant quality... The substances added to the water used in the central heating system are corrosive. Over time, scale settles in the pipes. Leaks appear under the influence of corrosion. For this reason, it becomes necessary to replace pipes and batteries. It is not recommended to install aluminum radiators and steel panels in high-rise buildings.

Which company radiators are better for an apartment

How to connect a heating radiator

When restoring a heating system or installing a new one, a natural question arises - which radiators to choose so that they are not only efficient and heat the home well, but also fit perfectly into the interior. Despite the fact that the appearance of heating elements is important, first of all, you should pay attention to technical characteristics, such as operating pressure, temperature limit, as well as the material from which the batteries are made. However, which heating radiators for an apartment is better to choose among all the variety on the heating system market? Let's try to figure out the main criteria for choosing heating devices.

Read in the article:

Which is better to choose a heating radiator for an apartment

The water coming from the centralized water supply to the heating system goes a long way, carrying various chemical and mechanical impurities, which slowly but surely lead to the destruction of pipes and heating elements. Not the least role in the failure of the radiator is played by frequent water shocks, which cause the devices to burst and leak, flooding everything around with hot water. Therefore, before choosing heating radiators for an apartment, you need to study the main criteria that high-quality and efficient heating devices must meet.

What you should pay attention to in the first place is the metal from which the radiator is made, in particular, its physical and chemical parameters. The battery must withstand a pressure 1.5 times that created in the heating circuit. For example, in Soviet houses this figure does not exceed 5-8 atm., While in the heating circuit of modern high-rise buildings it is 12-15 atm.

Also, the metal from which the heating battery is made must be resistant to sudden pressure surges in the system, to the so-called "water hammer". For your information, if it is noticed that clicks and hum are heard in the pipes, then it is better to contact the utilities, since this is a sure sign that not everything is in order with the pressure and it is better to immediately prevent the possibility of an accident.

Before choosing a heating battery-radiator, it should be borne in mind that the water in our water supply system is full of various chemical compounds and mechanical particles, therefore the metal used for the production of heating devices must be able to resist corrosion and other damage.

Heat transfer is an indicator of efficiency. Accordingly, if you want warmth in the room in winter, you need to choose heating radiators that have a high heat output.

Terms of operation. Everything is clear here, because the larger it is, the less often heating batteries will have to be changed, which means that there is an opportunity to save significant money and effort.

The design of the radiator is very important, since the heating device must harmoniously fit into the interior of the room. A huge assortment of heating devices on the market allows you to purchase batteries for every taste and budget, but at the same time makes it difficult to choose.

So, before choosing heating batteries for an apartment, you need to weigh the pros and cons and only then make a purchase and start installing them.

The main types of heating radiators for an apartment

As we already understood, the choice of radiators is not an easy task, and in order to make it easier for yourself, you first need to learn a little about the types of heating batteries in apartments in modern houses.

Advantages and disadvantages of cast iron radiators

Nondescript and massive cast-iron radiators are familiar to the older generation since the existence of the USSR. Modern cast iron radiators look neater and sleeker. Like everything in this world, a cast-iron heating battery, the price of which fluctuates depending on the model and manufacturer, has its advantages and disadvantages.

The advantages include:

• long service life, which is over 50 years;
• resistance to corrosion;
• undemanding to the purity of the coolant;
• long-term preservation of heat, in cases of shutdown of the heating system;
• acceptable cost.

The disadvantages are that cast-iron batteries heat up for a long time, are heavy, are difficult to install and are practically not protected from hydraulic shocks.

General technical characteristics of cast iron heating radiators MS-140-500

The standard section has a volume of 4 liters and a weight of 7.5 kg. The heating area is 0.23 m 2. Heating occurs due to convection flows (no more than 20%), and the rest is due to radiation. That is why cast iron batteries are mounted under windows.

Heating batteries made of steel

Steel heating radiators are available in two versions - panel and tubular. Schematically, panel batteries look like two steel panels, 1.2 mm thick, with stamped channels for the coolant and welded together. For greater efficiency of the radiator, 2-3 panels are connected parallel to each other. As a result, such a steel three-panel battery, the size of a cast-iron analogue, weighs almost the same, and with a thickness of 160 mm. even exceeds it. Having decided to buy steel heating radiators for your apartment, you need to take into account that the indicators of panel batteries, in terms of heat transfer, are no better than cast iron models.

Among the positive aspects of panel radiators, it is worth noting:

• Efficiency up to 77%;
• high heat transfer;
• environmental Safety;
• low cost.

The disadvantages, the owners of steel panel heating radiators, include:

• susceptibility to corrosion;
• inexpediency of installation in high-rise buildings due to the high risk of water hammer;
• the convection inherent in this type of battery contributes to the formation of drafts.

Consumer interest in tubular steel heating radiators is more caused by a variety of shapes, which makes it possible to fit this heating device into almost any interior. Tubular batteries are stronger than panel ones due to the 1.5 mm wall thickness and can withstand up to 16 atm. For this reason, steel radiators are installed only in houses with autonomous heating.

The advantages of this type of battery are:

• high working pressure;
• greater efficiency compared to panel counterparts;
• corrosion protection.

In principle, comparing panel and tubular radiators, it is worth noting that their strengths and weaknesses are almost the same. However, having the ability to withstand higher working pressures, tubular steel radiators are much more expensive than panel counterparts.

Aluminum radiators

Heating radiators are also produced in two modifications - cast and extrusion. This nuance must be taken into account when deciding which aluminum radiator to choose for your apartment.

Cast battery sections are made individually from an aluminum-silicon alloy (silumin). Sewing takes place at increased pressure, which makes it possible to obtain sections of the most different shapes that can withstand 6-16 atm. For strength, the walls of the battery are made thick, and expanded channels for water are created for free circulation of the coolant. Cast sections can be combined into a single battery

Elements of extrusion aluminum batteries are made separately, by extrusion and then connected together. This method is cheap, but in such a radiator, you cannot remove or add a section.

Structurally, aluminum batteries are more perfect than their cast iron counterparts. The aluminum section is 110 mm deep. against 140, the heating area is 0.4 m 2, and the volume is 0.5 liters. Heat transfer by convection and radiation is about the same - almost 50% each. When adding new sections, the heating area increases to 0.5 m 2, which increases the proportion of the convection component to 60%. Heat transfer indicators of an aluminum heating radiator in the table presented after the types of batteries.

Positive characteristics of aluminum heating radiators:

The disadvantages are:

• short service life;
• susceptibility to corrosion;
• vulnerability to water hammer;
• tendency to leak.

And we will complete the listing of the advantages and disadvantages with a rating of an aluminum heating radiator.

Bimetallic batteries: pros and cons

The design of these heating devices successfully combines the strength of steel and the thermal conductivity of aluminum. Bimetallic radiators are capable of withstanding pressure up to 35 atm., And well withstand water hammer. When deciding which bimetallic or other material heating batteries are best for an apartment, it is worth taking into account that radiators of two materials can be connected to the heating system in several ways to ensure maximum efficiency.

The image below is a sectional view that clearly shows the structure of this heater.

The advantages of bimetallic batteries include the following:

• high level of heat transfer;
• resistance to hydraulic shocks;
• a small amount of coolant is required for normal operation;
• ease of installation;
• attractive appearance.

Among the few disadvantages:

• lower heat transfer in comparison with aluminum counterparts;
• high price.

The given table of heat transfer of a bimetallic heating radiator and batteries made of other materials will help determine the choice of the desired design.

In principle, we figured out the types and brief characteristics of heating radiators, and now it is worth familiarizing ourselves with the basic calculations of the required number of sections, heat transfer and other characteristics.

How to calculate the required number of radiator sections

When reconstructing or creating a new heating system, in order not to suffer from the cold in a poorly heated room, you first need to carry out some calculations that will allow you to select and install effective heating devices. To select the necessary heating devices, as we have already found out, you need to know the material from which they are made, their resistance to corrosion, heat transfer from the heating radiator, the table was given above, the number of sections and much more. The required number of heating radiators is calculated in two ways - by the volume of the room or by its area. It is also necessary to take into account the estimated pressure in the central heating battery.

Basic calculations to determine the number of sections and heat output

Area calculation

It is believed that in order to compensate for the heat losses of a building and create a comfortable temperature regime for a person, it is required to provide a thermal power within the range of 100 W / m 2. You can use a calculator to determine the required number of heating radiator sections or make simpler calculations using the formula

N = S × 100 / Pc, where

• N - the number of battery heating elements;
• S - the area of ​​the room;
• Pc – thermal power of one element of the heating structure (data are indicated in the technical data sheet of the battery).

Volume calculation

To make a more accurate calculation of the number of heating radiator sections, they resort to calculating the volume of the room that will be heated. Moreover, for a brick house, the power of the heating system should be 34 W / m 2, and for a panel house - 41 W / m 2. Calculations are done using almost the same formula that was given above, but slightly modified:

N = S × h × 34 (41) / Pc , where

• h - ceiling height.

Of course, when deciding to purchase a one-piece non-separable battery, there is no need in the calculations to divide by the thermal power of 1 radiator element. Then the resulting value will mean the total power of the heating battery, which is required for a particular room.

It should be noted right away that these formulas will be correct only for standard average conditions. For this reason, when making calculations by volume or area, it is imperative to take into account the correction factors determined by the minimum winter temperature prevailing in the region of residence, the location of the room, the degree of wall insulation, the number and type of windows, and the location of the doors. Even the installation layout and location of the radiators can play a big role in calculating the thermal power of the battery.

It is rather difficult to list all this in one article and therefore it is best to use a special calculator.

Buying a heating radiator (RO) is not a trivial task. There are many models, they cost differently, and it is not always clear which of the items presented on the store shelves meets our requirements. Therefore, we will save your time and tell you what to be guided by when choosing. We bring to your attention rating of the 20 best heating radiators for an apartment and a private house. Choose any of them - you won't go wrong!

For a private house or apartment?

There are tens and hundreds of companies specializing in RO production. The competition is fierce. Marketers are coming up with new arguments in favor of their products. This makes the choice in terms of characteristics richer, and making a purchase for an ordinary buyer more difficult. Let's start with the simplest.

If you need a device for a private house or apartment with an individual heating system, then choose according to power and design. Those. they saw the model they liked externally, picked it up in terms of power / size - and that's it. For an apartment in a multi-storey building, where the coolant is supplied through the pipes of a centralized heating system, it is also necessary to take into account the working pressure set by the manufacturer. It should not be lower than 10-12 atmospheres. Otherwise, the structure will break when water is supplied.

And now let's figure out the types of heating radiators, traditionally presenting the data in the form of a "tiny" table.

* Before choosing a device, you need to check with the ZhES the maximum pressure in the heating system. Remember that all radiators except aluminum are suitable for a centralized heating system!

** We are often asked about how to choose the right heating radiator in terms of power. To make life easier for you and yourself, we have developed a handy calculator. Use it to your health!

For those who want to estimate the thermal power on their own, you can use the following technique. Determine the required values ​​per unit area of ​​the room: 100 W / m 2 - one window and one outer wall; 120 W / m 2 - one window and two outer walls (corner room); 130 W / m2 - two windows and two outer walls (corner room). For example, there is a corner room of 20 m2 with two windows. Then the estimated power of the RO will be: 20 × 130 = 2600 W. Let's make an allowance for the fact that the passport characteristics of the radiators are tied to the ideal operating conditions of the device - 10% is quite enough. In total, we get the required thermal power: 2600 × 1.1 = 2860 W.

It remains only to decide on the desired model, which you can find among the 20 devices we have selected.

In addition to the heat exchanger itself, do not forget about the control valves (thermal head) and the Mayevsky valve (if not included), which must be purchased separately. This also applies in some cases to mounting kits. For one-pipe heating systems, a bypass is required.

We offer you a small rating, which contains the best models of heating radiators. To make it easier to compare, we tried to choose devices with the same number of sections - most often there will be 6 of them. This borderline solution is the most demanded for standard apartments. All prices are for comparison purposes only.

5 bimetallic radiators

1. Global STYLE PLUS 500, 6 sections - from 4600 rubles.

STYLE PLUS 500 model of the famous Italian manufacturer Global. STYLE PLUS 500 features an increased safety margin - the product can withstand pressures up to 35 atmospheres - as well as an increased diameter of vertical channels connecting horizontal collectors. To seal the joints of the sections, special silicone gaskets are used, designed for contact only with prepared water - other types of coolants are not allowed. This bimetallic product is designed in such a way that air pockets do not form inside, preventing the correct operation of the device. The guarantee is 10 years.

2. RIFAR ALP-500, bimetal, 6 sections - from 3800 rubles.

In 2002, the Russian company Rifar quickly broke into the field of production of heating radiators for private houses and apartments, and since then has achieved considerable success. The main specialization of RIFAR is the development and production of bimetallic and aluminum devices. In the model of the bimetallic radiator RIFAR ALP-500, high heat transfer is achieved due to the developed lateral surface of the section. Therefore, the design turned out to be very slender - only 75 mm thick! On sale there are models with the number of sections from 4 to 14, connected through silicone gaskets, which provide uncompromising tightness. RO can be made in any of the colors of the RAL 9016 palette. However, it should be borne in mind that the coolant for such a device should only be specially prepared water - "anti-freeze" used in heating systems of private houses will not work here. 10-year warranty.

It differs from other solutions in the absence of sharp corners. The warranty is 20 years. However, it should be borne in mind that the mounting kit is non-standard, not available everywhere on sale, so it is better to buy it first.

4. Rifar Monolit 500, bimetal, 6 sections - from 5600 rubles.

It is no coincidence that the Monolit 500 model from the previously mentioned manufacturer Rifar appeared in our rating. Everything is due to the fact that the Russian company has really succeeded in developing innovative solutions for heating. The product fully justifies its name - it is monolithic, the sections are conditional here, because they are welded together, forming an integral structure. Thus, the possibility of coolant leakage is reduced to zero. This RO can withstand pressure up to 100 atmospheres! Plus, there are practically no restrictions on the coolant used. The manufacturer's warranty is 25 years.

5. Royal Thermo PianoForte 500, bimetal, 6 sections - from 9,000 rubles.

5 cast iron radiators

16. Viadrus Styl, cast iron, 6 sections - from 9000 rubles.

Positioned by the Czech manufacturer as designer, but in fact - almost classic cast-iron radiators also got into our small rating. Unlike their counterparts, the capacity of each of the sections of such a reactor is small, which means that the amount of heat received can be quickly varied. The disadvantage of this approach is low power. With regard to the advantages, one cannot fail to note the possibility of side and bottom connection. A thermoregulatory valve is already built into the product for this purpose. Various color solutions are possible. Manufacturer's warranty - 10 years.

17. MLOO MS-140M-05, cast iron, 7 sections - from 3500 rubles.

19. Arbonia Karotherm KM90 - from 100,000 rubles.

The Swiss-German Arbonia design radiators are in the premium segment for the price, so you should not be surprised at such a high cost. What does a renowned manufacturer offer us? A stainless steel product that will be an organic addition to the interior of a modern home. It is at home, because it has a working pressure limit of 4 atmospheres. This device can only be considered as an auxiliary RO, because its thermal power is small, and an increase in size (and power) can increase the cost to sky-high heights.

20. GuRaTec Apollo 765/05, cast iron, 5 sections - from 33,200 rubles.
