When choosing an aluminum radiator, it is important to take into account several important factors. First of all, it is necessary to determine the heat conductivity of the apartment. If there are windows in the room that are not hermetically sealed, then they may cause a large amount of heat loss. That’s why you should determine the correct amount of the junctions of aluminum radiator. It depends on the size of heated space. For example, if the heating area is 20 square meters, then another additional radiator is required to install for equal heat distribution.
