BTUs are ‘British Thermal Units’, the unit in which radiator efficiency is measured. Factors such as room dimensions, window size and wall material are used to calculate the required outputs of radiators, in order to adequately heat a room. Use our BTU Calculator to determine the heat requirements of your room.
To use the heating BTU calculator, you will first need to measure the place you want to heat up. You need to know if you’re heating up a 1000 sq ft, 1500 sq ft, or a 3000 sq ft home, or a 400 sq ft room, for example. Secondly, you need to figure out what climate zone you live in.
BTU or ‘British Thermal Unit’ is a unit of heat. 1 BTU is enough heat to raise the temperature of 1 pound of water by 1°F. US households require anywhere from 20,000 BTU to 300,000 BTU of heating output in the winter. To calculate how many BTU of heating output you need, you have to know only 3 factors:
The British Thermal Unit, or BTU, is an energy unit. It is approximately the energy needed to heat one pound of water by 1 degree Fahrenheit. 1 BTU = 1,055 joules, 252 calories, 0.293 watt-hours, or the energy released by burning one match. 1 watt is approximately 3.412 BTU per hour.
