heat calculator

The output of radiators is measured in BTU or watts. The dimensions and construction type of a room are used to culculate the BTU/watts required to heat it. It is easy to calculate the radiator heat output you need to heat your room. You can find the heat output of all our radiators in the product description. Remember that towel rails are not normally expected to heat a room.

This is a guide only. A radiator with insufficient output may never raise the temperature to that required. Outdoor temperatures, external walls, insulation, heated adjacent rooms (i.e. above, below and to the side) all play a part. The boiler should be able to supply all connected radiators to the sum of their maximum demand.
