Heat pump vs gas cost calculator
Compare what it costs to heat your home with a heat pump versus a gas furnace. Enter your rates and efficiencies to see estimated annual cost for each and your likely savings.
How it works
- Estimates your annual heating energy from home size and climate.
- Costs it for a gas furnace at your gas price and efficiency.
- Costs the same heat for a heat pump at your electricity rate and COP, then compares.
What changes your result
- Your electricity rate and local gas price
- The heat pump's efficiency (COP / HSPF)
- Your climate and how cold winters get
- The efficiency of the gas furnace you're comparing against
Frequently asked questions
Is a heat pump cheaper than gas heating?
It depends on local energy prices and the heat pump’s efficiency (COP). Where electricity is moderately priced, heat pumps often beat gas because they move 2.5–4 units of heat per unit of electricity. This tool compares using your own rates.
How efficient are heat pumps in cold weather?
Modern cold-climate heat pumps work well below freezing, though efficiency falls as it gets colder. Many keep a COP above 2 near 0°F. In cold snaps, backup heat may engage, which the COP setting lets you reflect.
Will a heat pump lower my energy bills?
Often yes, especially replacing electric resistance, oil or propane. Versus cheap natural gas the savings are smaller and depend on local prices. Running the comparison with your actual rates shows whether it pays.
