Individual heating in the apartment

Centralized heating systems of apartments are currently not satisfied with many, because they do not give the desired comfort. Residents freeze at the beginning of the cold period of the year, waiting for the beginning of the heating season. Then, when the batteries are hot, and it warmed on the street, people open the windows because they are tormented by stuffiness. A lot of effort goes to the fight against mold, condensate and dust that provoke radiators, and how much you have to pay for heating, you should not even mention.
