Heat Pump vs Furnace Calculator
Work out what a heat pump would actually cost to run compared with your current heating, using your own bill and local rates.
Illustrative prices and performance. Converts variable heating fuel spending to delivered heat and prices that heat at your seasonal COP. Excludes fixed charges, cooling, maintenance, financing and future price changes. Fuel heat content is approximate; use a seasonal COP that includes backup heat.
How the math works
units burned = annual cost ÷ fuel price delivered heat = units × BTU per unit × efficiency heat pump kWh = delivered heat ÷ (3,412 × COP) heat pump cost = kWh × electricity rate
Frequently asked questions
Will a heat pump be cheaper?
The fuel price, electricity rate, current efficiency and seasonal heat-pump performance determine the result. Neither technology always has the lower running cost.
What seasonal COP should I enter?
COP is delivered heat divided by electricity used. Use a local seasonal estimate for the proposed system, including defrost and backup resistance heat. A single laboratory rating or HSPF label value is not a seasonal COP.
Will a heat pump meet my winter heating load?
Check the specific equipment capacity at your local design temperature and any backup heat requirement with the installer. This cost calculation does not size equipment.
Does this include cooling?
No. Cooling, maintenance and replacement timing may improve or worsen the comparison. Excluding them does not make the result automatically conservative. Compare equivalent complete installation quotes.
