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 65oF / 18oC multiply the volume by 4, 4 rooms requiring 70oF / 21oC multiply by 5.
