Cost to heat a home in Wisconsin
Cheapest to run in Wisconsin is
a gas furnace
A gas furnace costs about $3 a year less than a heat pump here. Cheap gas relative to electricity is the reason, and no amount of equipment efficiency closes that gap at these prices.

About the cold
Wisconsin sees about 155 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 Wisconsin?
No. At Wisconsin's prices a gas furnace costs about $2438 a season against $2441 for a heat pump, so switching would raise running costs by roughly $3 a year. Cheap gas, not poor equipment, is the reason.
What does it cost to heat a house in Wisconsin for a winter?
Between about $2438 and $6081 for a 1,800 square foot home, depending entirely on the system. Wisconsin runs around 7,200 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 Wisconsin that difference is about $3640 a season.
