Cost to heat a home in Massachusetts
Cheapest to run in Massachusetts is
a heat pump
A heat pump costs about $351 a year less than a gas furnace here. That is a consequence of Massachusetts's prices, not of the equipment — the same comparison goes the other way in states with cheaper gas.

About the cold
Massachusetts sees about 130 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 Massachusetts?
Yes. At Massachusetts's prices a heat pump costs about $3025 a season against $3375 for a gas furnace — roughly $351 less a year for the same heat.
What does it cost to heat a house in Massachusetts for a winter?
Between about $3025 and $7535 for a 1,800 square foot home, depending entirely on the system. Massachusetts runs around 5,900 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 Massachusetts that difference is about $4510 a season.
