Hourly operating costs are impacted by the BTUs for the product and the price of natural gas or propane.
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.
