Radiator BTU Calculator

The efficiency of radiators, old and new, is measured in British Thermal Units (BTU).  The dimensions of a room are used to calculate the amount of BTU needed to heat that room. Radiators all have a known and calculated BTU output. Using the BTU outputs it is easy to calculate the size of radiator you need to heat your room.
