*The amount of heat produced by a heating appliance is measured in British Thermal Units (BTUs). One BTU represents the amount of energy required to raise the temperature of 1 lb. of water by 1 degree F. Generally, more BTUs correlate to greater heating potential. However, the amount of BTUs needed to heat a specific area varies, based on climate and home efficiency.
