How this heat pump vs electric heat savings calculator works
Resistance input energy equals heat demand ÷ efficiency. Heat-pump input energy equals heat demand ÷ seasonal COP. Both are multiplied by the same electricity rate.
How to use it
- Annual heat delivered. Enter the value in kWh thermal.
- Resistance efficiency. Enter the value in %.
- Heat pump seasonal COP. Enter the value that applies to your situation.
- Electricity rate. Enter the value in $/kWh.
- Request the result. Select “Show my result.” No account or email is required.
What to do with the number
Seasonal COP depends on climate, equipment and operating temperature, so this is a scenario comparison rather than a utility-bill forecast. Use a seasonal performance estimate for your climate instead of the unit’s best-case laboratory COP.
Planning estimate
Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
