Why is it so important to consider the dimensions of aluminum heating radiators?
Aluminum — a lightweight material that is widely used.
Among other things, heating batteries are made from it.
In their creation it is very important calculation of characteristics.
The influence of the size of the aluminum heating radiator
Aluminum batteries come in a wide range of sizes. Length has a primary effect on power.
Accordingly, to achieve the required heating it is necessary increase the number of sections. The total length of the battery depends on the calculations.
Depth and height also change the values because they affect volume. Unlike length, these two meanings - variable, due to which there are many different models.
The next indicator is - center distance. It is responsible for the speed of heating of radiators, since it means the gap between the supply and return pipes.
The performance is also affected by the manufacturing method:
- Metal casting increases the strength and durability of the device. In this case, each section is a single unit from which the device is assembled. This is done in a certain sequence: first, the upper parts are welded, then the lower ones.
- Extrusion method involves forcing heated aluminum through a metal lattice plate. This produces a profile of a given shape, which is then divided into parts and assembled into a radiator.
Attention! Such heating devices are rare and are usually made to order. This is due to inability to make changes into the design after production is completed.
Center distance
The indicator is the gap between the radiator axes. They are located symmetrically, one on top, one on the bottom. They are connected to pipes through which they are connected to the heating circuit.

Depending on the manufacturer, the value varies. in the range of 150-2000 mm. Most devices have this indicator equal to 500. This is related to heating systems in apartment buildings: in old buildings, calculations are made for cast iron radiators. When replacing batteries, the costs of rewelding the pipeline are undesirable.
Reference! Most models have this in their name number, indicating the center distance.
Depth
Depends on the material the battery is made of. The minimum value is 52 mm. It is sufficient to create high power of small sections. The maximum indicator is 180 mm. It is quite rare and requires strength. There are models with greater depth, but their use is impractical due to insufficient heating.
Determining the volume of a section
To calculate, you need to know the value described above, as well as the length and height. First meaning, visually - width.
She makes up 80 or 88 mm, what is indicated in the passport.
Second — variable. Usually the vertical component of the section dimensions is — 570 mm.
To find the volume, it is enough multiply three indicators.
Section Calculation Method
To determine the required number of elements, you need to determine the power. There are several rounded values calculated for a room with ceiling height 2.7 meters:
- For a standard room you need 100 Watts.
- For each window add 10 each.
- If it is angular, the value multiply by 1.2.
- If the ceilings are higher or the windows are larger than usual, add 10%.
- Heating weakens from the upper floors to the lower ones, so for each one you should add another 2% each.
The obtained standard power multiplied by the area of the roomThe result is a total value calculated with a margin.
Then the number is divided by Passport indicator of one section, rounding up. The approximate calculation looks like this:
- (100 + 10) * 1.2 * 1.04 = 137.28, where the extreme multiplier is chosen for the apartment third from the top floor.
- 137.28 * S = 151 * 18 = 2471, where S (18) - square.
- 2471 / 190 = 13. In this case, at power one section of 190 watts will require 13 pieces.
Radiator weight
Aluminum is a light metal. Products made from this material have a small mass, which makes them easier to move and reduces the time required for installation. strengthIt should be noted that in the manufacture of batteries, metal is alloyed with silicon. This slightly increases the weight.
The average weight of one section is 1.25 kg. The value varies between from 1 to 1.35, which depends on the dimensions and thickness of the walls. For example, for mounting a radiator from 10 units with a small reserve of sufficient fasteners by 15 kg.
Important! Of all types of radiators, aluminum ones the easiest ones. This makes them easy to transport.
Height and width of non-standard radiator shape
There are batteries of unusual appearance. The device can be created from metals up to three meters high, up to two meters wide.
The depth of vertical devices, taking into account the fastenings, rarely reaches 100 mm.
The volume of radiators of other shapes depends on their dimensions. The size varies depending on the manufacturer, but there are also items made to order.
To find out their characteristics, you should refer to technical data sheet.

The dimensions of the battery affect warm, which she transmits to the premises. In order not to make a mistake in the calculations, it is recommended to invite specialist, which will help you with your choice.
