An important point is the correct calculation of the right number of bimetallic radiator sections. Such a calculation is carried out, taking into account many parameters of the room: heated area, ceiling height, heat transfer of radiator sections, number of windows, etc.D. In order not to make a mistake in complex calculations, it is better to contact consultants. Modern heating systems can be painted independently. Radiators should be painted with disconnected heating. Consider the fact that the radiator painted in dark tones gives heat better. Usually paint radiators no more than once every 10 years.
