Which heating radiator is better to choose for an apartment - analysis of four options. What are the best heating radiators for an apartment? Indoor heating radiators how to choose

In the current market, which is saturated with varieties of heating devices from many manufacturers, it is sometimes very difficult for the average homeowner who has decided to replace batteries to choose suitable products for their home. Our goal is to help solve this problem and figure out which batteries are best installed in an apartment or in a private house.

Overview of heating radiators

Walking into a large heating equipment store, you get the feeling that there are countless types of heating batteries. In fact, there are only five of them:

cast iron products;
steel heaters;
aluminum radiators;
bimetallic batteries;
electric heating devices.

All these types of heating radiators have different technical characteristics, as well as their advantages and disadvantages, which determine their scope of application. Let's take a closer look at each of them, and clearly determine which type of device is best placed where.

Cast iron radiators

This type of water heater, familiar to us from childhood, is still used to this day, despite the emergence of many modern competitors whose technical characteristics are much better. This is due to several reasons, for example, the high corrosion resistance of cast iron and the ability to work in systems with high coolant pressure. In addition, for many people, tribute to tradition is important and, despite any explanations, they are still convinced that cast iron batteries are the best.

This opinion has a basis, since these devices are very reliable and durable; according to these criteria, they have no equal, since they last from 30 to 50 years. In addition, cast iron heaters retain heat for a long time, having great massiveness and inertia. This advantage is also a disadvantage: cast iron batteries take a long time to heat up and take just as long to cool down, so it is very difficult to organize automatic climate control in the room where such devices are installed.

If previously the appearance of cast iron batteries left much to be desired, now many companies offer cast iron heating radiators with various powder coatings or decorative casting.

True, this improvement has taken traditionally cheap heaters out of the budget category, since such products are much more expensive. Their other disadvantages are well known: large weight and water capacity, although recently these have been reduced to a minimum.

What’s good about cast iron batteries is that they can be installed everywhere: in an apartment, house, or cottage. But it is best to use them for heating a private house where a gravity system is organized. It itself is inertial and has a large volume of coolant flowing at a low speed. This is exactly what a massive cast iron appliance needs.

Steel batteries

This type of heaters is divided into two types

panel;
tubular.

Panel radiators are good radiators for a private home, where the operating pressure of the coolant does not exceed 3 Bar. The fact is that their design and manufacturing technology provide for operation in a system with a maximum pressure of up to 15 Bar. This is often not enough in conditions of centralized heating, especially in high-rise buildings.

The panels have good heat transfer, relatively light weight and size, and are also distinguished by their aesthetic appearance. There are also steel radiators with bottom connections, which makes it possible to install them in apartments with individual heating and piping hidden in the floor.

In addition, among all heating devices, steel panels have the lowest cost, so they often remain the only acceptable option. Disadvantages include sensitivity to corrosion and a relatively short service life (up to 15 years).

When you need to install a steel radiator in a central heating system, it is better to choose a tubular type device that has thick, massive walls that can withstand high pressure and water hammer. Therefore, such batteries can be installed anywhere, they are reliable and durable.

Another thing is that the cost of tubular devices is quite high, and there are disadvantages similar to cast iron batteries: inertia, large capacity and considerable weight. Because of this, they are rarely installed in country houses and other buildings with an individual heating system, preferring the same heaters made of cast iron or aluminum.

Aluminum radiators

One of the most popular heating devices - sectional aluminum batteries - are distinguished by the best degree of heat transfer, fast heating and cooling, low weight and remarkable appearance.

All these advantages are realized thanks to the device body made of aluminum alloy. It contains vertical channels with a cross-section close to circular, and on the outside these ducts are equipped with many ribs that intensively transfer the energy of the coolant to the air in the room. In turn, the flat surfaces of the aluminum battery produce a uniform flow of radiant heat. The physical properties of aluminum make it possible to organize automatic control of heating power, since inertia in this case is practically absent. A small capacity (up to 0.25 liters of water in each section) also contributes to rapid heating.

Aluminum radiators for the home are easy to assemble and install due to their simple design and low weight of the products. They can be attached to any building structures, even plasterboard partitions. You just need to correctly calculate the required number of sections for heating the room; sales representatives or online consultants of online stores will always help you with this.

As for the shortcomings, there are only two. The first is similar to steel panels: a low threshold for maximum operating pressure (up to 16 Bar), which makes the installation of aluminum batteries in centralized heating systems risky. The second is ordinary and electrochemical corrosion of the alloy due to exposure to low-quality coolant from central heating networks. Therefore, aluminum ones are the best radiators for any individual heating systems, where the quality of the coolant is controlled by the homeowner himself, and the pressure in the system is controlled by the boiler automation. But in apartments with central heating it is better to install bimetal.

Bimetallic radiators

In fact, bimetallic batteries are the same products made of aluminum, inside of which there is a welded frame made of steel pipes with thick walls. As a result of this modernization, the shortcomings associated with the quality of the coolant and its pressure were successfully eliminated.

At the same time, the heaters have slightly less heat output than purely aluminum ones, but much more than those of steel or cast iron appliances. Therefore, in the case of centralized heat supply systems for heating, it is better to install bimetal radiators; they will serve for a long time and reliably, while releasing heat much more intensely than other types of devices. But it should be said that the cost of bimetallic batteries is significantly higher than aluminum ones.

Conclusion

Before we draw the line, it’s worth saying a few words about products such as electric heating radiators. They are very effective and easy to install, all they need is a 220 V outlet. Another thing is that the cost of electric heating is quite high, so heaters are often used as additional heat sources.

From the above we can conclude that the choice of batteries largely depends on the type of heating system. If you have the financial opportunity, it is better to install aluminum appliances in a private home as they are the most economical. When this is not possible, then steel panels will do, and with a gravity system - cast iron heating devices. The same applies to apartments with an individual heat source. But in centralized networks, cast iron or bimetallic batteries, as well as tubular steel ones, would be appropriate. The choice largely depends on the homeowner's budget.

Not only the efficiency of the heating system, but also its durability depends on the choice of suitable batteries. Therefore, this step is very important and special attention is given to it. You also need to take into account that heating in apartment buildings is most often centralized, which means that the batteries will be exposed to various dangers, for example, water hammer. Which heating radiators are best for an apartment? Our detailed review will tell you about this, in which we will look at the radiators available on sale and find out which of them are suitable for apartment installation.

Features of centralized heating systems

Scheme of central heating in apartment buildings.

Heating a multi-storey building requires the construction of a large boiler room, where a powerful gas boiler is installed. From here, thick pipes are sent to the house, through which the coolant moves. And the higher the multi-story building, the higher the pressure of the coolant, since it needs to rise to a greater height and pass through hundreds of radiators, overcoming high hydraulic resistance.

As for multi-storey buildings with individual apartment heating, they are much less common. This is how houses with a height of 3-5 floors are built, where it is more profitable to create several autonomous heating systems than to build and maintain a common boiler room - this requires additional funds and additional human resources to maintain boiler equipment. But the pressure in autonomous systems is much lower - the batteries will be relatively safe.

As you may already understand, the main enemy of heating batteries in apartment buildings with a centralized heating system is high coolant pressure. Due to this, batteries often begin to leak, or even burst, when exposed to pressure from water. Subsequent repairs result not only in replacing the batteries themselves, but also in a complete renovation of the apartment (sometimes not your own, but the neighbor’s).

It must be remembered that the higher the building, the higher the pressure in the pipes. The highest rate is in modern buildings up to 20-26 floors (and higher).

Centralized heating systems also pose other dangers:

Water hammer instantly increases the pressure in the heating system and not all radiators can withstand it.

Water hammer - they occur as a result of pressure changes. If boiler room employees open the coolant supply too abruptly, or shut it off just as abruptly, then the pipes and heating radiators in the houses will suffer a powerful blow. And many radiators, for example, aluminum ones, may not withstand such exposure and burst, flooding rooms and household items with hot water;
Low quality coolant is another factor that negatively affects not only pipes, but also radiators. It often contains quite active chemical components that spoil the metal. Corrosion is also affected by fine mechanical impurities of various origins - they have no less negative effects on radiators and pipes;
Temperature changes - it cannot be said that they have a direct effect on heating equipment, but as the temperature rises, the pressure also increases. Therefore, some batteries simply cannot stand it and burst, since they are not designed for such temperature loads.

Which batteries are best to install in an apartment?

We already know what threatens radiators in centralized heating systems. This is high pressure and water hammer - the rest can be neglected (to some extent). How do you still choose heating radiators for an apartment and what are the requirements for them? Everything here is easy and simple, as will be described below.

Resistant to high pressure and water hammer

The best heating batteries for an apartment are those that can withstand high pressure. The higher the house, the higher the maximum possible pressure in the battery should be. You also need to remember about possible water hammer, so this figure is doubled. If we consider that the pressure in the heating systems of high-rise buildings reaches 15-16 atmospheres, then the batteries must withstand a maximum pressure of up to 32 atmospheres.

Corrosion resistance

Many radiator models are susceptible to corrosion. Electrical corrosion, which can occur at the junction of different metals, is especially dangerous.

Far from pure water flows in the pipes of heating systems. There are also quite aggressive components used to clean pipes and radiators from traces of corrosion. Along with rust and scale, aggressive components also eat through metal. And if the same cast iron can still boast of durability, then aluminum is subject to destruction under such influence. Mechanical impurities require the use of thick-walled metal that is resistant to mechanical stress.

Design and brand

Which heating batteries are better for an apartment, and which ones are better for a home? In private homes, we are free to use any heating radiators, since there we are independently responsible for the absence of water hammer and for the quality of the coolant. Therefore, there we often use fairly cheap radiators, which do not require great endurance (especially if an open-type heating system is installed in the house).

As for apartment buildings, you need to pay attention to the most durable batteries from leading brands. For example, these could be heating radiators from Kermi, Global or Fondital. Products from German manufacturers have the best quality, but here you need to be prepared for high costs. But such radiators can be used in heating batteries of any type - they are as reliable and durable as possible.

As for Chinese batteries, there is always a chance of running into trouble. For example, some manufacturers openly “cheat” by reducing the thickness of the metal. As a result, the batteries are thin and flimsy. Therefore, it is best to rely on European brands.

Modern models of cast iron radiators, made in an antique style.

Battery design plays a huge role. Recently, thin panel and sectional radiators have become the most popular. They have an attractive appearance and good efficiency - manufacturers do everything possible to combine high build quality, excellent design and high heat dissipation. An interesting fact is that cast iron batteries have begun to appear on the market again, but now they have a rather interesting retro design.

It is cast iron batteries that can withstand almost any trouble that heating systems can create. But this comes at the cost of their bulkiness and low efficiency.

High heat dissipation

Since we are talking about efficiency, then When choosing radiators, you need to pay attention to heat transfer. The higher this parameter, the warmer it will be in your apartment at the same coolant temperature. Some models of aluminum and bimetallic heating radiators have a heat output of up to 200 W or more per section. For old cast iron batteries, this figure is approximately one and a half times higher, but they are more reliable and durable.

Which radiators to choose for heating an apartment

Which heating radiators are best to choose for your apartment? Consumers can choose from cast iron, steel, aluminum and bimetallic radiators. Let's try to figure out how they differ from each other and which of them are best suited for apartment installation.

Cast iron radiators

These are the oldest radiators on the heating equipment market. They are distinguished by their solid dimensions, as they are made of thick cast iron. Such radiators can withstand pressure changes, resist water hammer and high temperatures. They are also capable of working with aggressive coolant. Everything would be fine, but they are characterized by low heat transfer, which makes them somewhat unsuitable for use in cold regions.

Their disadvantages also include:

Inconvenient to install due to high weight;
Not very attractive external data;
Not suitable for use in high-rise buildings (above 5-9 floors).

Otherwise, these are good radiators, durable and strong. Recently, quite modern models have appeared on the market, with acceptable dimensions and decent appearance. And they can be installed in low-rise buildings, where they will serve for many years.

Steel radiators

Looking at modern steel panel radiators, you immediately begin to understand that they clearly cannot withstand high pressure. And this is true, because thin metal is used here, which is not particularly durable. Steel radiators can be useful for heating small private houses or country estates, but they are not suitable for use in high-rise buildings.

The only exceptions are some models of steel radiators through which relatively thick pipes pass - their endurance is somewhat higher. They are often called tubular radiators. Today they are found in some buildings with a height of 9-16 floors.

Steel radiators have high heat transfer and heat rooms well. They are also very light and do not pose any difficulties during installation. An undoubted advantage is the small internal volume. But all these advantages become useless if you need to install these radiators in an apartment - in low-rise buildings they will still serve (the use of tubular models is required), but in high-rise buildings they will not withstand high pressure.

Aluminum radiators

Modern aluminum radiators are lightweight and have high heat output. And aluminum itself is a fairly strong metal. Radiators made from it are ready to withstand high coolant pressure, but there is no resistance to water hammer. An equally disadvantage is the lack of resistance to the effects of coolant - aggressive impurities literally corrode such radiators, leading to ruptures and leaks.

The appearance of aluminum radiators captivates with their magnificence - they are compact and neat, they are easy and pleasant to install, but the lack of resistance to water hammer and corrosion spoils everything. But they can be an excellent solution for private households.

Sometimes it is allowed to use aluminum radiators in low-rise construction, where the coolant pressure is not as high as in high-rise buildings. They are also successfully used in apartments with individual heating.

Bimetallic radiators

If you don’t know which heating radiators are best to install in an apartment, then we recommend that you turn your attention to bimetallic models. Inside them we will find:

Steel base - it can withstand pressure up to 50 atmospheres and resists corrosion well;
The aluminum body, which is not in contact with the coolant, provides simply excellent heat transfer.

Bimetallic radiators are not afraid of water hammer and high pressure; they are easy to install and dismantle. They are also resistant to high temperatures and are lightweight, and thanks to the presence of effective corrosion protection, they can boast a long service life. Exactly bimetallic radiators are the best for installation in apartments, be it a small three-story building or a solid 26-story building.

Despite many advantages, bimetallic batteries have one disadvantage - their high cost. Therefore, the costs of purchasing them will be quite significant.

The choice of heating devices for a water system always remains the prerogative of the homeowner, even when the installation is carried out by hired craftsmen. But choosing batteries based on the advice of sellers or reviews of Internet users is not easy - the former often do not understand the topic and repeat advertising slogans, the latter “praise their swamp,” which is understandable. To find out which heating radiators are best to choose for an apartment or private house, we suggest using a simple and understandable algorithm.

Instructions for choosing batteries - a simplified approach

We hope the previous description helped you figure out which heating batteries are best for an apartment in terms of price and technical indicators. Finally, here are some practical tips:

Please use the instructions at the beginning of this publication. Choose radiators that best suit your design and budget.
The operating pressure of the coolant is important only for apartments in high-rise buildings; only bimetallic and aluminum batteries can withstand pressure above 10 bar. Any water heating devices are suitable for dachas and private cottages.
If you are on a limited budget, feel free to buy steel panels - their heat output is not inferior to other heaters or convectors.
For a gravity-flow system, you need to take radiators with a large cross-section of internal channels. It is better not to install stamped steel heaters, only tubular ones.
In terms of price-quality ratio and set of operating parameters, the first place is occupied by sectional batteries made of light aluminum alloy.
It is worth paying for bimetal when there is no confidence in the parameters of the coolant - the pressure is unknown, hard water is used.
Try not to purchase frankly cheap radiators made from unknown material in China. They will warm, but probably not for long.

Characteristics of heaters of the same size, made of different materials - comparison table

Conclusion regarding cast iron. Heating radiators of the old type MS-90 and MS-140 are cheap, but they look unsightly. Beautifully designed models are incredibly expensive, and therefore beyond the reach of average homeowners. Cast iron is becoming rare, and the outdated “accordions” of the MC series are becoming a thing of the past.

If your budget allows you to install designer heaters, carefully select each battery according to its dimensions. It is better to place a vertical steel heating radiator in a narrow wall niche, and stylish cast iron products under the windows. It is advisable to additionally attach heavy floor-standing versions to the wall using a pair of brackets.

Residents of southern countries do not care about the problem of winter cold and home heating. But in our conditions, no house or apartment without heating devices will be considered a sufficiently cozy room. In village huts, the good old stoves are still preserved, but for urban housing a water heating system is more suitable.

In the process of repairing and changing the appearance of the apartment, a desire arises to replace old batteries with more modern and practical ones. But how can an ignorant person choose heating radiators so that they heat effectively and look beautiful?

Advantages of water heating

The principle of its operation is the same for both a city apartment with a centralized coolant supply and for cottages with their own heating boiler. Hot water, flowing through pipes and radiators, carries heat to each room and heats them evenly. Then, gradually cooling, the water returns back to the water for a new portion of heat.

Compared to the use of electric heaters or underfloor heating systems, water heating is more efficient and economical. Most practical.

The problem of choosing radiators

Modern city dwellers are trying to install heating batteries of new models in their homes to replace those that have served their useful life. But with the current assortment, it has become difficult for the consumer to make a rational choice. The characteristics of heating radiators differ quite significantly. And the aesthetics of the appearance of the radiator should correspond to the style of the home interior.

The buyer needs to take into account many criteria: among them are the design of the radiator, the type of metal, heat transfer and power.

Cast iron. They differ from old “Soviet” batteries only in that they are newer. Their disadvantages remain the same - large mass, poor heat transfer and a rough appearance. Even the low price does not justify the use of cast iron batteries in modern homes. One advantage, perhaps, can be called the durability of cast iron, the experience accumulated over the years by specialists and its resistance to corrosion.

Aluminum. These radiators are considered the most popular on the market. I am attracted by their lightness, strength and beautiful design. Aluminum has the ability to conduct heat well, so this metal is well suited for the manufacture of heating devices. Aluminum radiators are available in two types. One of the modifications is suitable for use in apartments with central heating and high pressure in the system. Another model can be used in private homes with a lower pressure load.

Steel. These radiators are most often used to heat country houses. The simplicity of manufacturing steel products allows you to give radiators an original, attractive look. This type is aesthetically attractive. High heat transfer along with affordable cost make them one of the favorites among buyers. One of the disadvantages is poor resistance to sudden water hammer.

Bimetallic. The name of these radiators makes it clear that they are made of two types of metal. Steel pipeline elements are laid under the aesthetically pleasing aluminum shell. This technology provides a guaranteed ability to use them at any pressure. They also have high resistance to internal corrosion. The high price due to the complexity of the design makes them less accessible.

Power is an important characteristic

Depending on the type of room where the heating radiator will be installed, you will have to make some calculations. It is necessary to determine in advance the required power of heating radiators so that you do not have to freeze in the room later.

Different types of radiators have different capacities. The radiator power characteristic is a value that determines the heat transfer efficiency of each of its sections. So, one battery section has a power (W):

cast iron - 80–150,

aluminum - 190,

bimetallic - 200,

steel (entire radiator) - 450–5700.

When making calculations, we must not forget about important points: wall thickness, room size, number and type of windows, etc. It is believed that in a standard apartment room with one window and a door, it is enough to install a radiator with a power of 90–125 W per 1 square meter.

10% if the window faces north;

20% if the radiator is hidden under a solid decorative panel;

30% if the room is corner and has two windows.

The “safety margin” characteristics should also be added to the power category. This indicator determines the radiator’s ability to withstand the maximum coolant pressure. For cast iron it is 10–15 atm, for aluminum 16 atm, bimetal can withstand 35 atm, and steel only 6–8 atm.

Methods of wiring and installation of radiators

It does not matter what type of battery is purchased, but the general rules for installing them remain standard. It is better to entrust it to an experienced plumber to do the right job. It is very difficult for a homeowner who is far from technical problems to determine the angle of the pipes or find the right place to mount the radiator.

Only a professional will tell you which type of connection to prefer: one-sided, bottom or diagonal. It is advisable to resolve such issues in contact with the designer who creates the interior project. He will express his opinion on how organically the radiators can fit into the overall design style.

Painting for beauty and protection

After the most careful installation of system elements, chips and scratches still form on the surface of the radiator. In other cases, batteries are repainted to refresh the paint or to change the color.

It is important to understand that not all paint can be applied to radiators. The most suitable paint for heating radiators should, firstly, be heat-resistant. It must withstand temperatures up to 100 degrees, keep up with the metal and not change color.

There are special paints for heating radiators; they are durable and protect the metal well. Paints containing metal powder (bronze, aluminum) also have good heat resistance.

When answering the question: “How to choose heating radiators?”, you should not lose sight of many little things. The most complete consultation can be obtained in the store when you are directly acquainted with the product. This will help you purchase the most suitable product.

Video on the topic of choosing heating radiators:

Many people are forced to live in difficult climatic conditions. Not everyone can move to more suitable 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 aesthetically pleasing! So which heating batteries are better 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 devices should be selected with extreme care, 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 characterized by low cost, excellent thermal conductivity, durability and the ability to retain heat even after the heating is turned off. Their disadvantages include slow heating, the need for frequent maintenance, fragility, consumption of large amounts of water and poor tolerance to water hammer. Aluminum systems have high heat transfer, 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, but 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 resistant to high pressure.

Price. Water heating devices are considered the cheapest, so when purchasing 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 on average 350 rubles per section, bimetallic ones - about 600 rubles per section, and steel ones 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 W. 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.
