Heat-pump savings rankings

Which states favour a heat pump on running cost — and which still favour gas.

Heat-pump savings vary widely by state because they hinge on the ratio of electricity price to gas price and on climate. These rankings use a reference 2,000 sq ft home at each state's default climate zone. Pick a list below, then check your state page. Estimates, not quotes.
