This central heating boiler BTU calculator will give you an estimated guide to the heat output in BTU and Watts needed for one room only.
Outdoor temperatures, external walls, insulation, heated adjacent rooms (i.e. above, below and to the side) all play a part in determining boiler BTU output. The boiler should be sufficient to supply all connected radiators to the sum of their maximum demand.
As a rough guide, measure the Height, Length and Width of the room and input them into the calculator below. Then click on whether you measured in feet or metres to get your BTU output.
