THIS CALCULATOR 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 suffient to supply all connected radiators to the sum of their maxmium demand.
