Is a heat pump cheaper to run than a gas furnace?

Heat pump (COP 3.0) vs 96% AFUE gas furnace: heat pump wins if electricity ($/kWh) / gas ($/therm) ratio < (100 / (AFUE% × COP × 29.3)). At $0.12/kWh and $1.50/therm: heat pump is cheaper by ~30%.

Do heat pumps work in cold climates?

Cold climate heat pumps (ASHP) rated for operation at -13°F (-25°C) are now available (Mitsubishi, Bosch, Trane). HSPF2 ratings of 7-10 (8.2+ is ENERGY STAR) ensure good efficiency even at low temperatures.

What is the heat pump break-even gas price?

Break-even gas price = electricity price × COP × 29.3 / (AFUE/100). With $0.12/kWh electricity and COP 3.0 heat pump vs 95% AFUE furnace: break even at $10.55/MMBtu or ~$1.05/therm gas.
