In order for the room to be warm and cozy all year round, it is necessary to correctly calculate the number of batteries to be installed in each specific room. For this, several conditions must be met. One of them is the technological features of the heating radiator itself.

## Types of heating batteries and their characteristics

To date, there are several varieties of heating coils:

- Melting. This is one of the most reliable, durable and proven representatives. Its main feature is slow heating rate and high heat transfer during operation. It holds more water than other heaters, and when it cools down, it can give off heat for a long time. As a result, these batteries will require much less than others.
- Aluminum. Differs in high heat transfer and maximum heating rate. It is lightweight and easy to install.
- Steel. It has the smallest liquid capacity, and therefore the smallest heat transfer.
- Bimetallic. In appearance, they resemble aluminum ones, however, they have one important feature, which is the presence of a metal interior, with the help of which the lightness of aluminum and the strength of metal are combined.

## Ambient heat loss

The second important characteristic is the heat loss, which is typical for each particular room. The less heat loss there is, the fewer radiators will need to be installed. This parameter is checked using a special device called a thermal imager.

There are several reasons for a leak:

- walls;
- the window;
- ventilation;
- ceiling.

## heat dissipation

Another important characteristic is the heat transfer of a section. That is, to calculate the number of radiators, it is necessary to take into account the amount of heat that one section can give off. The cast iron battery has the highest heat transfer. Which is able to accommodate the maximum amount of liquid.

## Types of calculations

The simplest is the calculation of the number of heating radiators depending on the area of the room. If the height of its ceilings corresponds to the frame from 2.7 to 3 m, then after calculating the number of radiators, the obtained result should simply be multiplied by 100 W (the standard figure adopted for heating 1 m²) . Any heat losses are compensated by adding an additional 20% from above. To find out how many radiator sections you need, the final value is divided by the heat transfer of one. If there are a lot of windows in the room, its walls border the street, then another 15% of the thermal power must be added, which means that the number of sections must be increased.

On the other hand, you must take into account the space that the room has. Since hot air tends to rise, a room with a higher ceiling will heat up much more slowly than a room with a lower ceiling.

Based on the above, when calculating the number of batteries, all the main parameters of the room should be taken into account, from the number of windows to the height of the ceiling and floor. That is, all components are important in determining the heat loss in the room. If there is the highest quality insulation, the heat loss will be minimal. Otherwise, you will have to install a much larger number of sections than necessary.

If you have additional questions, you should seek the advice of a specialist who can perform an accurate professional calculation.
