Radiators
A radiator's output is measured in British Thermal Units per
hour (BTU/hr) and each radiator should have enough capacity to heat
the room it is fitted in, to the optimum temperature. The BTU/hr is
calculated by multiplying the height, width and length of the room
to get the volume in cubic feet. For rooms requiring 65°F/18°C
multiply the volume by 4, 4 rooms requiring 70°F/21°C multiply by
5.
