Calculating the number of sections in the bimetallic heating radiators

Calculating the number of sections in the bimetallic heating radiators

How to calculate the number of sections in the bimetallic heating radiators - this question torments many people who have decided to change the heating system in the house.

After Bimetallic radiators deservedly popular in many homes and apartments.

Ability to adjust the number of sections and calculate the required number of them makes it easy to select a heating system for large offices, and for a very small room.

Today Bimetallic radiators become a real replacement for outdated cast-iron batteries.

Section correctly calculated for the room can give a sufficient amount of heat during the cold season.

This fairly easy to install compared to other heat sources such as radiators and are of high quality, durability and reliability.

Their only disadvantage - price.

fact by complexity and high cost of materials, such sections are not cheap, especially when compared with the same cast-iron units.

Therefore, it is especially important to know how to calculate the number of radiators, or rather,

their sections.

There is always taken into account such characteristics as power.That it is necessary to calculate and take into account with great responsibility.


material from which made sections, can also affect the procedure for calculating, for these or other metals give off heat in different ways.

So before you count the number of sections, it is necessary to understand how to choose such radiators and what their operating principle.

  • How many sections should be in the radiator?
  • Additional factors and nuances

Features choice bimetallic radiators

For qualitative heating in the room set, modern and compact bimetallic radiators.Such designs are well suited for private homes and apartments.

Actually, the name "bimetallic" appeared on the double structure of the device.A radiator located inside the iron core and the outside - aluminum fins.

calculated that it is steel and aluminum are the ideal combination for the heating system, as the first for maximum tensile strength, while the second has a remarkable thermal conductivity.

In addition, these metals provide an excellent combination of both apartments, and for the house.

It turns out that such sections are ideal for projects with central heating and private.

fact that aluminum, steel, and perfectly kept the pressure drops in any system that makes them quite versatile.

For example, if one uses a flat copper pipe, and the other - aluminum, there is nothing to worry about.

Of course, you can choose a combination with copper, which is also in demand in the radiator market.But the price of copper today is impressive.

Compare radiators

If you have a small room in the apartment - it's still not a bad option.But for the few rooms in the house radiator replacement can cost quite expensive.

In general, we can distinguish the following main types of radiators:

  • considered the most traditional cast-iron construction.They are characterized by long life, good given the heat and the pressure is maintained, but very cumbersome, they are hard to change;
  • aluminum sections, the number of which may not be very large, show a remarkable power, are relatively inexpensive, with their appearance fits perfectly in many interior solutions;
  • Bimetallic radiators in high demand today, as combine several advantages of metal vapors.It is also believed that they quickly and efficiently transfer heat than find fame affordable heating systems;
  • There is a category of steel radiators that are made of high-strength materials.Correctly calculate the number of such sections allows heat necessary area without difficulty.

Whatever the type and number of sections has not been selected, we should not forget that over time, this heating system will lose its power and heat.

choosing a more powerful design, you can reduce the load on the boiler.Therefore, it is believed that counting the number of required sections, you need to take a few more options for the stock.

To calculate the correct number of elements into account technical characteristics, heat transfer and capacity of each section.

These parameters indicate in the passport to the device.Also estimate the area of ​​a house or apartment.

radiator power calculation for heating

When you select the number of sections for heating, the logical question is: Do I need to buy a large, but a warm radiator, or limited to small and hot model?

When installing small batteries over time, you can simply increase the temperature of the coolant, which is also called "high-temperature heating."


can calculate heat transfer by all the rules for a particular house or flat, how much heat is needed for heating and the exact parameters of the battery.

here means that the radiator will operate at lower power.Obviously, with such an embodiment of the overheating safety will be tangible, and it will be possible to save on heating.

It is often at high heating Bimetallic radiators are heated so that you can burn yourself, putting a hand to them.

Therefore, in order to heat a room, it is necessary to choose a low-temperature method.

defined the type of heating, you can proceed to the calculation of the area of ​​bimetallic radiators.And this can not be done without knowing the capacity of the batteries, or the room temperature is far from comfortable.

To calculate how much concrete you need bimetallic sections, you need to know the volume of the room.To this end, the length of the room should be multiplied by the height of the ceilings and the width of the room.

Required power or heat depend on the type of room.

For example, if the count rates for a panel apartment, which has a good insulation of the walls, then there per cubic meter will account for 0.04 kW.

When it comes to modern homes, where met all standards of thermal insulation, the capacity is only 0.02 kW per 1 cubic meter of space.

also important to consider in the bimetallic heating radiators for indicators such as the specific heat flow.

on how much of this value depends on the speed of movement and space heating the coolant in the sections.This option should always be to learn from the sellers or the data sheet.

How many sections should be in the radiator?

Perhaps calculate the number of sections that should be enough for the bimetallic radiator heating systems, it is essential for the room, so it was not always cold and uncomfortable.

necessary to use a special formula.Thus, the volume of space is first multiplied by the characteristic quantity of thermal energy (for each room has its own value).


resulting number is divided by the rated battery current.That is why we say that this value to be recognized in advance at the store or the manufacturer's website.

may result can not be called a whole, so it is rounded up.For example, if you got 9.2, it should be rounded up to 10.

However, the disposition of the number of sections?You can put one in the radiator 10 branches, or choose two designs by the five elements in each.

Here it is necessary to assess the heating power, and area of ​​the room.For example, if the room is quite large, it is more logical to use more than one heating appliance.

can further calculate the circulation of warm air stream, but without it, it is clear that a number of sources of heat to be uniformly heat the area - it's better than a bimetallic radiator.

Additional factors and nuances

should be understood that the above method, which allows you to calculate the power and the number of required sections is very simplistic.

It is suitable for standard houses, where the ceiling height, for example, no more than three meters, and the coolant flowing through the pipes, the temperature is not above 70 degrees.

So, if you live in a cold region where winter temperatures are much lower than typical rates, it is necessary to multiply the figures by the correction factor of 1.1.

significant for the northern regions, but not for the middle band.

And if the corners of the room, it is also taken into account.Here it is necessary to multiply the results by 1.2.In addition, each window adds energy consumption indicators 100 watts.

This is due to the fact that even with good insulation through cracks still in the room gets a small amount of cold air.

Also if the room area covers more than 25 square meters, for the heating of standard indications is small.The result is multiplied by 1.2.

If the coolant temperature in the battery is below 50 degrees, the calculations should be carried out taking into account the (multiplied) by a factor of 1.5.


also plays the role of the place of installation of bimetallic radiators.It is best to set them under the windows to cover the heat losses in this place.

also need to choose a design to an already assembled form, if you plan to self-assembly.

properly connect all the sections will not be easy, because they have to withstand very high pressures.

wiring diagram is better to think in advance a detailed plan, vymeryat all sizes.

It is understood that there are several connection schemes for heating.When you connect the lower heat losses are considered to be large.

better to give preference to the side or diagonal installation process.
