Heat Pump Savings Calculator
Calculate how much you can save by switching to a heat pump.
Compare costs vs gas furnace, oil, or electric resistance heating.
Heat Pump Savings
How heat pumps save money:
Heat pumps move heat rather than generating it, making them 2-5x more efficient than other heating methods.
Coefficient of Performance (COP):
COP = Heat delivered / Electricity consumed
A COP of 3.0 means for every 1 kWh of electricity, you get 3 kWh of heat.
Typical COP values:
- Air-source heat pump: 2.5-4.0
- Ground-source (geothermal): 3.5-5.0
- Gas furnace: 0.80-0.96 (80-96% efficient)
- Electric resistance: 1.0 (100% efficient but costly)
- Oil furnace: 0.80-0.90
When heat pumps save the most:
- Moderate climates (most savings)
- Replacing electric resistance or oil heat
- Where electricity is cheap relative to gas
