Heat Pump vs Electric Resistance Heating Cost in Wisconsin

💡 Quick fix: A heat-pump-aware smart thermostat (with aux-heat lockout) cuts 10-20% on top of the heat pump itself.See top smart thermostat →

In Wisconsin’s very cold climate (effective HSPF 7.0), a heat pump cuts your heating bill by about 51.3% versus electric resistance baseboard — $1685/year instead of $3458/year. Annual savings: $1772.

Heating type	kWh used / year	Cost / year
Heat pump (HSPF 7.0, COP 2.05)	8,774 kWh	$1685
Electric resistance baseboard (COP 1.0)	18,000 kWh	$3458

Assumes 18,000 kWh of delivered heat per year — typical for an 1,800 sq ft home in a very cold climate. Wisconsin’s electricity rate: 19.21¢/kWh.

20-year cost-of-ownership in Wisconsin

Over a typical 20-year heat-pump life, switching from resistance heat saves a Wisconsin homeowner about $35,447 on electricity. A typical cold-climate heat pump install runs $8,000-$15,000 — paying back in roughly 5.6 years against a $10,000 install. For very-cold climates like Wisconsin, look specifically for ENERGY STAR cold-climate models (CCHP) rated to maintain capacity below 5°F.

How we calculated this

A heat pump’s seasonal heating coefficient of performance is HSPF ÷ 3.412. With HSPF 7.0, that’s a seasonal COP of 2.05 — meaning 2.05 units of heat delivered per 1 unit of electricity consumed. Resistance heating delivers 1-to-1.

For the same 18,000 kWh of heat per year, the heat pump needs 8,774 kWh of electricity; resistance needs 18,000 kWh. Multiplied by Wisconsin’s residential rate (19.21¢/kWh from the EIA), that’s the costs above.

FAQ

Does a heat pump work in Wisconsin’s winters?

In a very-cold climate like Wisconsin, you need a cold-climate heat pump (CCHP) rated to maintain ≥75% capacity at 5°F. Modern CCHPs work well to -15°F or lower. Pair with backup resistance strips for emergency cold snaps.

What about gas heating?

If you have access to natural gas, the comparison is different — at typical 2025 gas prices, heat pump and gas furnace heating costs are often within ±20% of each other in Wisconsin, with the exact ranking flipping based on local gas vs electricity prices. Heat pumps also do cooling (a single system, two seasons), while a gas furnace needs a separate AC.

What is the federal tax credit?

As of 2026, U.S. homeowners can claim a 30% federal tax credit (up to $2,000/year) for ENERGY STAR-rated heat pump installations, which materially shortens the payback period above.
