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.

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.
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.
