Fuel Efficiency Calculator

The following energy savings calculator was developed by the Hearth, Patio & Barbecue Association and is provided for estimating purposes only. Actual energy savings may vary based on use and other factors.

A central furnace cycles on and off several times an hour and heats your entire house – even unoccupied rooms – wasting money. Using a supplemental hearth appliance to heat the rooms your family occupies most, or "zone heating," allows you to turn down the thermostat for the central furnace, decreasing your fuel bill.

A good way to determine the energy savings a hearth product provides depends on the fuel, fuel cost and the efficiency of the hearth appliance (along with use and your home). The following calculator can assist you in determining the cost saving benefits of the hearth product that you are considering purchasing, and the best fuel of an appliance.
