How Wisconsin compares
Wisconsin ranks 15th most expensive of 50 places with a real heating season when each uses its cheapest option, and 15th for a gas furnace. Its gas figure of $1,023 is 23% above the US average of $831.
The climate explains part of it. Wisconsin averages 7,439 heating degree days a year (1991-2020 normal, weighted by where people live), 1.8 times the contiguous US figure of 4,230, so the same house needs 93.7 million BTU of heat a winter against 53.3 nationally. The rest is prices: electricity at 18.2 cents per kWh against a US average of 17.3, and the fuel prices below.
Is a heat pump worth it in Wisconsin?
On running cost alone, an air-source heat pump costs $2,579 a year here. That is $2,038 a year less than heating oil, $515 more than propane and $2,410 less than electric baseboards. A gas furnace is still $1,556 a year cheaper where gas service is available.
Because Wisconsin is in a cold climate zone, these figures use a cold-climate heat pump rating of 6.6 HSPF2 rather than the 8.1 printed on most labels. A cold-climate model listed by NEEP holds its output better below freezing; a standard unit will lean more on backup heat.

Lowering the bill
- A setback schedule on a smart thermostat trims heating energy by about 8% by ENERGY STAR's estimate, about $82 a year on the natural gas furnace figure here.
- A space heater only saves money if the rest of the house is allowed to cool. At 18.2 cents per kWh a 1,500 W heater costs about $0.27 for each hour it runs on high; see what a space heater costs to run.
- Air sealing and attic insulation lower every number on this page in proportion, because they cut the heat the house needs.
Wisconsin heating cost FAQ
How much does it cost to heat a house in Wisconsin?
For a 2,000 sq ft home with average insulation in a normal Wisconsin winter: $1,023 with a natural gas furnace, $2,064 with a propane furnace, $2,579 with an air-source heat pump, $4,617 with a heating oil boiler, $4,989 with electric resistance heat. That uses EIA prices for Wisconsin and its 1991-2020 normal of 7,439 heating degree days.
What is the cheapest way to heat a home in Wisconsin?
A natural gas furnace, at about $1,023 a year for our reference home. The next cheapest is a propane furnace at $2,064, and the most expensive is electric resistance heat at $4,989. If you have no gas line, the choice is usually between a heat pump, propane and oil.
Is a heat pump cheaper than oil or propane in Wisconsin?
Yes against oil: about $2,038 a year less. Against propane it costs about $515 a year more. That already uses a cold-climate rating of 6.6 HSPF2, lower than the 8.1 label figure, because Wisconsin winters are cold.
How much heating oil or propane does a house in Wisconsin use in a winter?
Our 2,000 sq ft reference home needs about 796 gallons of heating oil in an 85% efficient boiler, or 1,079 gallons of propane in a 95% furnace, in a normal Wisconsin winter. Smaller or tighter homes use less; a cold winter uses more in proportion.
