Without fail, the calculation of heating radiators must be done before proceeding to the issue of their purchase. At least it looks logical. After all, if you do not calculate the required number of sections, there will be no opportunity to purchase the required amount of goods.
It’s worth mentioning right away that the calculation of the number of heating radiators should be carried out by a specialist, because in addition to the fact that he will have the necessary experience and knowledge in this area, he has special software available.
But, despite this, to know the basic principles of such an event as the calculation of
heating radiators, obviously does not hurt. So, it is accepted that the standard amount of power needed to heat one square meter is 100 kW. But the fact is that this is exactly the standard value. That is, if the room has only one
window block and a standard floor height, then it certainly will do. However, this does not happen everywhere and not always.
It is also worth considering that if a room has two or more external walls, then the calculation of heating radiators should be carried out on the condition that the total power will be increased immediately by 20 percent. But at the same time, the installation of a plastic window with a double-glazed window allows to reduce this increase in power to nothing. The fact is that such windows perfectly retain heat.
Now let's move on. The calculation of sections of heating radiators is also influenced by the following factors: the presence or absence of an insulation layer; the material from which the walls of the room were made; radiator connection diagram; the presence of decorative grilles on those same radiators and so on. In fact, even if the window sill was too wide and it closes the radiator too much - this, again, requires an increase in heating power. Indeed, in this case, the heat flux is significantly deteriorated, which creates such a peculiar thermal curtain directly in front of the window.
If the ceilings in the room are higher than standard, again you have to increase the heating power. This happens by multiplying the increasing factor by the calculated power. At the same time, the increasing coefficient is the ratio of the calculated and actual heights.
After the calculation of the heating radiators was carried out, you can already decide on how many sections you need to purchase. For this, the total calculated power is divided by the heat transfer of one section. This parameter can be found directly in the store. You can also find out about it on the Internet on specialized sites. In general, counting the number of required sections is really not a problem provided that the total heating power is correctly calculated.
Well, of course, it is worth remembering that choosing a heating radiator is an extremely important task. Indeed, the correct functioning of the entire heating system directly depends on its solution. We can say for sure that few people have a desire to freeze on cold winter evenings.
