And centralized heating systems have fundamental differences that are taken into account when choosing equipment. Working hours autonomous heating a private house allows you to choose radiators based on the maximum heat transfer coefficient, materials with the best characteristics, high quality and optimal price... The operating conditions of the heating equipment of apartments differ sharply - here, reliability and resistance to loads are in the foreground. We will figure out which heating radiators are best placed in an apartment, where and how to buy them, and what users say in reviews about this equipment.

There are basically two different kinds heating of housing: centralized (open) and autonomous (closed). In the first case, steam or hot water from the boiler room or CHP is piped into the apartments multi-storey buildings... The second option is a separate heating system for a private house or cottage, which includes its own boiler, heat supply pipelines, radiators and pumps.

When determining which heating batteries are best for an apartment, we proceed from the operating conditions of radiators in such systems:

1. temperature from 100 ° С;
2. pressure up to 10 atm;
3. sudden pressure surges and hydraulic shocks during flushing of systems and secondary start-up.

When choosing a radiator, the consumer must know the load limit values ​​for the model in question.

Cast iron radiators

Resistant to high pressure and water hammer. There are models that can cope with heavy loads, but do not meet aesthetic needs. These examples include cast iron batteries, known to us since Soviet times. A good example modern cast iron radiators can be considered retro-style batteries that fit perfectly into the interior.

To the benefits cast iron radiators we attribute:

1. operating pressure 6 - 10 atm, peak loads 18 and more atm;
2. installation with different types pipes;
3. long service life;
4. high heat transfer (100 - 200 W);
5. quick change of size if necessary;
6. minimal corrosion.

Disadvantages of cast iron radiators:

1. heavy weight;
2. fragility;
3. slow heating and cooling, inability to control temperature.

Bimetallic radiators

For the production of such batteries, steel and aluminum are used. Inner surface such radiators, playing the role of a coolant, are steel.

Advantages of bimetallic radiators:

1. working pressure over 35 atm;
2. anti-corrosion resistance;
3. fast heating and cooling, no inertness;
4. modern attractive design;
5. light weight;
6. easy set of the required number of sections.

The disadvantage is the high cost.

Comparison of the two options does not reveal the superiority of either of them. Cast iron batteries cost 250 - 400 rubles per section in the normal version and 1500 - 6000 rubles in the "retro" version. Prices for bimetallic radiators are 400 - 1500 rubles per section, imported ones are more expensive. Outwardly, bimetallic batteries look more attractive: they are more compact, more modern, and easy to clean. Based on the cost, we consider bimetallic radiators for an apartment to be more preferable.

What heating radiators are best for a private house

Autonomous heating systems for private housing differ in other working conditions: low pressure and the absence of water hammer in the networks. The choice of radiators in this case is based on maximum heat transfer, price and quality. Any of the existing radiators is suitable for heating a private house. We will briefly consider the types of such equipment in order to choose which radiators are best for heating a private house.

Steel tubular and panel radiators

Such radiators are compact and visually attractive.

Advantages of steel radiators:

1. high efficiency;
2. corrosion resistance with properly prepared water;
3. long service life;
4. compactness and light weight;
5. low price.

Disadvantages:

1. not very good design;
2. the need for periodic flushing;
3. the need for constant filling to prevent corrosion.

Aluminum radiators

They are distinguished by modern design and excellent heat dissipation. Imported models are much more expensive than Russian ones, but we recommend buying them.

Special requirements for use:

• Careful control of the acidity of the coolant - aluminum corrodes quickly if this condition is not met.
• Due to the high heat output, uneven heat distribution in the room is possible. Accurate calculations are required before purchasing radiators.

In general, very good radiators for home heating. Subject to the rules of operation, they will last long enough. The price for aluminum radiators is relatively low.

Bimetallic radiators

Combined steel radiators ( interior) and aluminum fins. Such radiators are treated with a corrosion primer. They can withstand pressures up to 20-35 atm and are unpretentious to the composition of the circulating water.

The main disadvantage is the high cost. There are no water shocks and high pressure with autonomous heating, and the use of expensive radiators is impractical.

Cast iron radiators

The large thermal inertia of these radiators reduces the cost of heating the house. Cast iron batteries are corrosion resistant. At a price they are higher than aluminum and steel, but much lower than bimetallic.

The disadvantages of cast iron batteries are fragility and heavy weight.

When choosing which heating batteries are best for a private house, two groups should be considered - steel or aluminum batteries... Aluminum are more interesting - they are lighter, more economical and give off more heat.

Which bimetallic heating radiators are better

The choice of bimetallic batteries is large - the models are structurally different, in terms of characteristics, design and cost. Comparing the characteristics different radiators, we will determine which bimetallic heating radiators are better.

Bimetallic and semi-bimetallic radiators

Bimetallic radiators only have an aluminum upper part. They are made of steel, and then poured with aluminum under pressure. The coolant is in contact with steel. There are models in which the interior is made of copper. Such radiators are used with a coolant to which antifreeze is added.

The interior of a semi-metallic battery consists of two metals: steel and aluminum. Top Models such radiators are manufactured by Sira, Rifar, Gordi. They are not cheap, but the quality is excellent.

Sectional and monolithic bimetallic radiators

Monolithic radiators are characterized by a one-piece steel or copper collector, on which an aluminum "jacket" is put on. This design is called monolithic. Radiators of this type are more reliable than sectional ones, the weak point of which is the joints between the sections. Features of monolithic radiators:

• service life up to 40 years (2 times more sectional);
• working pressure up to 100 bar (3 times more than sectional);
• thermal power per section 100-200 W (equal to sectional).

The cost of monolithic radiators is about 20% higher than sectional ones, and it is impossible to change the dimensions by adding or removing sections. Big choice models allows you to select the desired radiator.

Bimetal radiator manufacturers

Imported radiators are presented on the Russian market by Italian, South Korean, and Polish firms.

Italian radiators

Represented by the equipment of companies Sira, Global Style and Radena. Cost 700 - 1500 rubles per section, service life from 20 years. Main characteristics:

• thermal power of the section 120 - 185 watts;
• maximum water temperature - 110 ° С;
• working pressure up to 35 bar.

South Korean radiators

Batteries from MARS with a copper core cost from 400 rubles with characteristics:

• thermal power of the section is 167 watts;
• maximum water temperature - 130 ° С;
• working pressure up to 20 bar.

Polish radiators

REGULUS-system equipment with a copper core is well known in Russia.

Specifications:

• working pressure - 15 bar;
• maximum water temperature - 110 ° С.

Russian radiators

The most famous are the batteries of the manufacturer Rifar, which cost 500 - 900 rubles per section.

Specifications:

• thermal power of the section is 100 - 200 watts;
• maximum water temperature - 135 ° С;
• working pressure up to 20 bar.

Chinese radiators

They are distinguished by low cost, modest design and low quality. If the budget does not allow you to buy quality equipment, then you can get by with a cheap "Chinese". At the same time, one cannot count on high performance, of course.

In my opinion, the RIFAR MONOLIT radiator is considered the best Russian product. Characteristics: thermal power of the section 134 - 196 watts; maximum water temperature - 135 ° С; working pressure up to 100 bar.

On the photo is a radiator of the RIFAR brand

Which aluminum radiators are better

Aluminum radiators are produced by Russian and foreign companies in a wide range. Major manufacturers include:

Rifar, Russia

The best Russian company. Prices are higher than the Russian average - on average 580 rubles per section. Main characteristics:

• working pressure up to 20 atm (maximum 30 atm);
• the maximum temperature of the coolant is 135 ° C;
• 10-year warranty, 25-year service life.

Royal Termo, Russia

• thermal power 140 - 184 W;
• working pressure 16 atm (check 24 atm).

Global, Italy

Renowned Italian manufacturer offers radiators excellent quality and elegant design. A section of such a radiator costs about 400 rubles. One of best offers on the market, taking into account the cost and quality.

SMART, China

A budget option for aluminum radiators. The design is simple, versatile, good quality. The cost of the section is about 300 rubles.

It is not difficult to choose an aluminum radiator - there are many offers in different technical and price categories. If you choose from domestic equipment, then Rifar radiators will be a worthy purchase, from imported we recommend the Italian Global. Of course, the proposals are the most general - when choosing a buyer, one should proceed from his own capabilities and needs.

Which heating radiators are better - aluminum or bimetallic

Comparison of bimetallic and aluminum radiators begins with the design and characteristics of the batteries.

1. Aluminum radiators consist of individual sections, which are connected by nipples. Gaskets are installed between the sections. Ribs with inside increase the heat transfer area.

2. The bimetallic radiator is composed of a steel core and an aluminum body with fins.

Comparative characteristics:

• In terms of heat transfer, aluminum is much preferable - already 10 minutes after turning on the room is warm.
• Aluminum radiators have a lower working pressure (up to 20 atm) than bimetallic (up to 40 atm), i.e. they can only be installed in autonomous heating systems of private houses.
• Aluminum radiators are more sensitive to the quality of the coolant. When the pH rises above 8, aluminum batteries will quickly fail.
• The limiting temperature for bimetallic batteries (130 ° C) is higher than for aluminum (110 ° C).
• The service life of bimetallic batteries is 15-20 years, aluminum - 10 years.
• The cost of bimetallic radiators is 20 - 35% higher than that of aluminum.

When choosing radiators, you need to take into account the conditions in which they will have to work. For autonomous heating of a private house, aluminum batteries are more suitable, for an apartment in a high-rise building - bimetallic ones.

Installation and installation of heating radiators

The high cost of installing heating batteries in an apartment or a private house often forces the owners to perform these works on their own. The cost of heating installation depends on the total volume, the number of installation elements, the selected connection scheme, the type and model of radiators, etc.

For self-assembly heating radiators are necessary:

1. familiarize yourself with the connection methods;
2. know the connection rules;
3. correctly calculate and accurately measure the location of the radiators;
4. have the tools you need for installation.

The heating battery is installed in such a way as to ensure maximum efficiency heating. The greatest heat loss is through the windows, therefore, the location of the batteries under the windows creates a thermal curtain, preventing the escape of heat.

The installation of radiators must be carried out strictly at right angles in the horizontal and vertical planes - incorrect location leads to air accumulation and rapid corrosion of the radiator.

Distances to be ensured during installation for normal heat exchange and warm air circulation:

• from the upper grill of the battery to the window sill - 5-10 cm;
• from the bottom edge of the battery to the floor - 8-12 cm;
• from the radiator to the wall - 2-5 cm;
• When installing reflective insulation on a wall, use longer hooks.

Calculation of the number of radiator sections

When buying radiators, find out how to calculate the required number of sections. It is better to collect sections in the store when buying batteries. Remember a simple rule: one section goes for heating 2 square meters area with a ceiling height of 2.7 m. Rounding up.

To install the radiators, you will need tools:

1. pliers;
2. screwdriver;
3. hammer drill;
4. wrench for branch pipes;
5. construction level;
6. tape measure, pencil.

Battery replacement is done in the following order:

1. the old battery is dismantled;
2. markings are made for attaching a new one;
3. brackets and battery canopy are installed;
4. assembly kit is assembled;
5. a valve, a valve under the thermal head and a Mayevsky valve are installed;
6. heating pipes are connected.

Installation of heating radiators with bottom connection in which hot water is introduced into the bottom of the battery and expelled from the bottom of the other side. Such radiators are outwardly more attractive, fit perfectly into the interior and allow you to hide the routing of pipes under the floor.

Thermostats for heating radiators

To regulate the heat supply during the heating season, we recommend installing a thermostat on each radiator. Installation of a thermostat on a heating radiator is described in detail on sites on the Internet. More sophisticated programmable thermostats will automatically turn on and off radiators, maintaining the desired temperature. You can install thermostats on each battery when two-pipe heating typical for a private house. At one-pipe system(in apartments of houses) to install a thermostat, a bypass is installed in front of the radiator - a pipe, perpendicular between the supply and "return". The diameter of the bypass pipe is always less than the diameter of the distribution pipes.

If the radiators close blackout curtains to the floor, then the circulation of warm air is disturbed and only the window is heated. A window sill that covers the top of the battery also interferes with normal air circulation. The efficiency of the radiator is reduced by 20%.

Heating radiator connection diagrams

Basic radiator connection diagrams:

1. Side one-way connection

Most commonly used and provides maximum heat dissipation. The supply pipe is connected to the upper branch pipe, the outlet pipe is connected to the lower one.

2. Bottom connection

It is used if the heating pipes are hidden under the floor or skirting board. The most aesthetically pleasing way. The supply and return pipes from below go vertically to the floor.

3. Diagonal connection

It is done with a large number of sections (more than 12). The supply pipe is connected to the upper branch pipe on one side, and the return pipe is discharged from the reverse side through the lower branch pipe. The Mayevsky valve on the radiators serves to remove excess air. Connection is inconvenient because when replacing or repairing a radiator, you need to turn off the entire heating system

4. Parallel connection

With this connection, the coolant is supplied through a heat pipe that is built into the heating system. The retraction also takes place. Taps at the inlet and outlet allow you to replace the radiator without shutting down the system as a whole. The disadvantage of this scheme is that at low pressure, the radiator heats up weakly.

conclusions

1. When choosing radiators for a private house or apartment in a high-rise building, one should take into account the operating conditions characteristic of autonomous or centralized heat supply. For an apartment, cast iron or bimetallic radiators are suitable, for a private house - aluminum or cast iron. Otherwise, you need to be guided by specific conditions: requirements for the interior, financial capabilities, equipment cost, manufacturer's reliability, etc.
2. We recommend that you check the calculation of the required number of radiator sections for a specific room after receiving the seller's recommendations upon purchase.
3. During installation, it is necessary to maintain all the necessary distances of the radiator from the floor, walls, etc., as well as the horizontal position of its position in different planes. The thermostat installed on the radiators helps to save money - you can turn off unnecessary radiators or set the automatic temperature maintenance mode.

Many people are forced to live in difficult climatic conditions. Not everyone can move to more acceptable regions, so most of the time they have to spend in well-heated premises. This suggests that heating systems should be as efficient as possible, and special devices for them should be aesthetically pleasing! So which radiators are best for an apartment, what are their prices? You will find the 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 distinguished by their low cost, excellent thermal conductivity, durability and the ability to keep heat even after the heating is turned off. Their disadvantages include slow warming up, the need for frequent maintenance, fragility, a large amount of water consumption and poor water hammer tolerance. Aluminum systems have high heat transfer, compactness, reasonable cost and a light weight, but at the same time they corrode. Steel radiators heat up quickly and are popular with customers for their low inertia and maximum heat transfer, and the most significant drawback of this type is the formation of rust. Bimetallic models are very demanding on the quality of water, but at the same time they are light in weight and are resistant to high pressure.

Price. Hot 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 - about 600 rubles per section, and steel in complete set will cost 2-12 thousand rubles.

Heat transfer. Non-sectional radiators (steel) have a total heat transfer 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.

The model has beautiful design and requires only 210 ml of water per section for normal operation. The disadvantages of the model include not very good sound insulation and a rather high percentage of rejects.

4. Global STYLE PLUS 500

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

Overview of heating radiators

Having entered a large heating equipment store, it seems 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;
• electrical heating devices.

All these types of heating radiators have different technical characteristics, as well as their own advantages and disadvantages that determine the scope of their application. Let's take a closer look at each of them, and clearly define which type of device is better to put.

Cast iron radiators

This type of water heaters, well known to us from childhood, is 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 pressure of the coolant. In addition, a tribute to tradition is important for many people and, despite any explanations, they are still convinced that cast iron batteries are the best.

This opinion is justified, since these devices are very reliable and durable, according to these criteria, they are unmatched, since they serve 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 warm up and cool down just as long, so it is very difficult to organize automatic climate control in the room where such devices are installed.

If earlier appearance cast-iron batteries left much to be desired, but now many companies offer cast-iron heating radiators with various powder colors or with decorative casting.

True, this improvement brought traditionally cheap heaters out of the budget category, since such products are much more expensive. The rest of their shortcomings are well known: high weight and water capacity, although recently they have been reduced to a minimum.

The good thing about cast-iron batteries is that they can be installed everywhere: in an apartment, house, dacha. 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 heater is divided into two types.

• panel;
• tubular.

Panel is good radiators for a private house, where the working pressure of the coolant does not exceed 3 Bar. The fact is that their device and manufacturing technology provides for operation in a system with a maximum pressure of up to 15 Bar. This is often insufficient in a district heating environment, especially in high-rise buildings.

The panels have good heat transfer, relatively low weight and size, and also have an aesthetic appearance. There are also steel radiators with bottom connection, 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 most low cost, so they often remain the only viable option. Among the disadvantages are sensitivity to corrosion and a relatively short service life (up to 15 years).

When you need to put a steel radiator in a central heating system, it is better to choose a tubular type device with 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, while there are disadvantages similar to cast iron batteries: inertia, large capacity and considerable weight. Because of this, they are rarely placed 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 radiators - are distinguished by the best degree of heat transfer, quick heating and cooling, low weight and excellent appearance.

All these advantages are realized thanks to the body of the device, made of aluminum alloy. Vertical channels with a cross-section close to circular are made in it, and on the outside these channels 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 emit an even flow of radiant heat. Physical properties aluminum make it possible to organize automatic regulation of the heating power, since inertia in this case is practically absent. Promotes rapid heating and small capacity (up to 0.25 liters of water in each section).

Aluminum radiators for the home are easy to assemble and install due to their simple design and low weight. They can be attached to any building structures, even drywall partitions. It is only necessary to carry out the calculation correctly the required amount sections for heating the room, in this you will always be assisted sales representatives or online consultants for online stores.

As for the shortcomings, there are only two of them. The first is akin to steel panels: low threshold maximum working pressure (up to 16 bar), which makes the installation of aluminum batteries in centralized heating systems risky. The second is the usual and electrochemical corrosion of the alloy due to the impact on it of a low-quality coolant from the central heating networks. Therefore, aluminum is best radiators for any individual systems heating, 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 put bimetal.

Bimetallic radiators

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

At the same time, heaters have a slightly lower heat transfer than purely aluminum ones, but much higher than that 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 giving off heat much more intensively than other types of devices. But it should be said that the cost of bimetallic batteries is significantly higher than that of aluminum ones.

Conclusion

Before drawing the line, it is 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 socket. Another thing is that the cost of electric heating turns out to be 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 there is a financial opportunity, then it is better to put aluminum appliances in a private house as the most economical ones. 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 steel tubular ones, will be appropriate. Much of the choice depends on the homeowner's budget.

The heating season is close, and you still haven't got heating radiators? We need to hurry, because few people want to catch the cold in cold apartment... Many users are interested in one important question: how to choose heating radiators by area? There are many nuances here that we will have to get acquainted with. Each heating element must be selected, starting with determining the amount of heat generated that is required for an apartment or house. This important indicator can be calculated different ways from the simplest to the most difficult. The lightest involve using the area and height of the room. Let's find the most accurate and optimal one.

Classical determination method

How to choose a heating battery by area if the height of the room is less than three meters? Everything looks something like this:

1. First, you need to determine the size of the room in which this radiator will be located. For example, let's take 25 square meters.
2. We multiply the resulting figure by 100 watts. For our case, the result will be - 2500 W.
3. We take the power that has turned out and divide it by the heat transfer of only one section of the device.

WITH panel radiators the story will take on a slightly different form. Panel batteries are a one-piece design that cannot be increased or decreased in size, so the full power will have to be taken into account. Installing such devices with a power of more than 2500 watts would be a huge mistake, since the calculation method would look very different.

Some features of the standard method

For the accuracy of the calculations, you need to enter the following adjustments:

1. The final value should be increased by 20% if the room is corner, that is, it has two outer walls.
2. The total power increases by 10% if the connection type is lower.
3. The total amount of heat should be reduced by 15-25% if the room has plastic windows.

Important! For each of the cases, the required amount of percent is added or subtracted to the final power. If each of these criteria is met, then the value of 2500 watts will turn into 2625 watts, then you will need to purchase a heating device for 18 sections.

The easy way

If you follow the instructions, then one radiator fin is required to heat two square meters. You should also pay attention to the fact that one more will have to be added to the total number of edges. For those cases where the room has a size of 25 square meters, you will have to take a device with 12.5 ribs. You need to round the value and add one more to it - you get 14. As you can see, this result less number, which was obtained by the classical method for the same room.

Of course, the absence of three sections will affect the heating of the room, which is why this method of calculation should be used only for an approximate result. Do not take the resulting value as a basis for choosing a radiator.

Important! Are you planning to install heating devices yourself? We have prepared a lot of useful and informative information on this topic:

Calculation for the second type of heating device

How to choose a heating radiator for a private house by area, if you need a panel type of devices? For this method, only one area of ​​the room is not enough, here we need its height, as well as a factor of 41. According to the standards, the battery should create 41 watts per unit cubic meter as you can see, we need to perform mathematical operations with the volume.

The algorithm looks pretty simple:

1. Determine the area of ​​the room.
2. Calculate the volume. To do this, simply multiply the area by the height.
3. Multiply the resulting value by a factor of 41.
4. The end result needs to be adjusted according to the criteria that were described just above.

Important! After all the actions, you should get the required power at the output. You can install one powerful heating device to achieve the goal. This option will be acceptable for those rooms in which there is one window, but if there are two or more of them, then it is better to use the action of two panel batteries with a heat transfer of 1250 watts at once.
