Description : We are about to renovate our apartment and I would like to know how many radiators to calculate for a room of a certain air size?
Last Answer : Multiply the floor area of the room by the ceiling height and multiply by 30-55 w. What we choose between 30-55W is influenced by the features of the building and the condition of the doors and ... w = 1.155 W. You can now select how many radiators to deliver heating power to the room.
