Don Tee Supplies LtdBTU Calculator - for guidelines only
Please use this simple BTU calculator but be advised:
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.
