# How to calculate the number of radiators ?

It is known to in the residential area was warm and inviting, it is required to establish high-quality radiators with adequate heat dissipation.If you need to replace outdated batteries, you need to calculate how many sections will need for a particular room.

## How to calculate the number of radiators for home

To determine how many sections will need to heat the room, you need to find out the power of the radiator.What matters is the material from which the product is made, and the quality of performance.Correct the manufacturer specifies a passport for this device option.For example, for cast-iron batteries it is 160 watts.For aluminum radiators - from 130 to 200W.Knowing this figure, it is easy to determine the number of sections needed.To do this, you need to square the premises divided by one hundredth of the value of power section.

To explain how to calculate the radiator section, we give an example.If the room - 22 square meters, and decided to buy a cast iron radiators, the calculation would look like this: (22 * 100) /160=13.75 sections.Of course, no one will buy thirteen sections "stump", so the result is rounded and output has fourteen.However, it should be noted that the alleged capacity of pig iron, as a rule does not correspond to the level of 160. Experts estimate that, in practice, under standard conditions, iron is able to pay much less "powerful" heat.Therefore, this formula does not always work in the real world.

But counting the number of aluminum sections in this formula will result in the end, is much closer to our reality.You need to divide the work (22 * 100) on the power of the model.

## How to calculate the heating radiators in any other way

Is there an easy way to count the number of sections of the radiator, which is very approximate.In this case, it takes little account of the stated capacity of the sections, so the results may not reflect reality.Calculate radiators can be as follows: we take the statement that one section of the cast-iron product is able to heat one square meter of space, and aluminum - 2 meters.Therefore, a 20 square meters of space needs iron sections 20 and 10 (!) - Aluminum.

Based on the above calculations, it is possible to judge the quality of different types of batteries.Cast iron radiators are old-timers, though, and fail-proof "campaigners", aluminum has long occupied the leading position.Of course, you can select and steel or bi-metallic products for their apartments, but they are not to the same extent as the two above-mentioned common monster.The first cheap - but short-lived, their efficiency is lower aluminum.The second (bi) - more expensive than aluminum, and heat on a level with them.And the big plus of these radiators - durability.Calculate the amount of bimetal radiators can also, like aluminum.But metal is not made for each section, so the standard calculation is not applicable here.
