Cost to heat a home in Maine
Cheapest to run in Maine is
a heat pump
A heat pump costs about $1260 a year less than a gas furnace here. That is a consequence of Maine's prices, not of the equipment — the same comparison goes the other way in states with cheaper gas.

About the cold
Maine sees about 165 freezing nights a year. That is enough that a heat pump needs to be a cold-climate model, and backup heat will run on the worst nights — which is already reflected in the figures above.
Common questions
Is a heat pump cheaper than gas heating in Maine?
Yes. At Maine's prices a heat pump costs about $4324 a season against $5584 for a gas furnace — roughly $1260 less a year for the same heat.
What does it cost to heat a house in Maine for a winter?
Between about $4324 and $10772 for a 1,800 square foot home, depending entirely on the system. Maine runs around 7,500 heating degree days a year.
Why is electric resistance heat so much more expensive?
It converts electricity to heat one for one, while a heat pump moves heat rather than making it and delivers two to three times as much per unit of electricity. In Maine that difference is about $6448 a season.
