Heat Pump Savings Calculator (Ontario)
Estimate how much electricity a heat pump could save compared to electric baseboard/resistance heating. Uses a simple COP model in plain English.

Quick guidance: COP changes with outdoor temperature. Try COP 2.0 for colder periods and 3.0 for milder periods.
Heating need
If you don’t know, start with a rough estimate and compare scenarios. This represents heat delivered to your home.
Efficiency + price
Optional: include delivery/GA changes you notice with higher usage.
How it works
- Electric baseboards are ~1:1 (1 kWh electricity ≈ 1 kWh heat).
- Heat pumps move heat. COP 2.5 means ~2.5 kWh heat per 1 kWh electricity.
- Higher COP = lower electricity use for the same heating output.
Educational estimator only. Real-world results depend on temperature, system sizing, backup heat, and how the home is operated.
