Formula
- Heat pump kWh = heat needed ÷ COP
- Cost = kWh × rate
Example calculation
15,000 kWh of heat at COP 2.8 and $0.13/kWh → $696 vs $1,950 with baseboards.
Practical HVAC use
Explain operating savings to homeowners using a realistic seasonal COP.
Common mistakes
- Using the rated COP at 47 °F as the seasonal average in a cold climate.
