Heat Pump vs Electric Resistance Heating Cost in Missouri

💡 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 Missouri’s cool climate (effective HSPF 8.0), a heat pump cuts your heating bill by about 57.4% versus electric resistance baseboard — $717/year instead of $1681/year. Annual savings: $964.

Heating type	kWh used / year	Cost / year
Heat pump (HSPF 8.0, COP 2.34)	5,118 kWh	$717
Electric resistance baseboard (COP 1.0)	12,000 kWh	$1681

Assumes 12,000 kWh of delivered heat per year — typical for an 1,800 sq ft home in a cool climate. Missouri’s electricity rate: 14.01¢/kWh.

20-year cost-of-ownership in Missouri

Over a typical 20-year heat-pump life, switching from resistance heat saves a Missouri homeowner about $19,283 on electricity. A typical cold-climate heat pump install runs $8,000-$15,000 — paying back in roughly 10.4 years against a $10,000 install.

How we calculated this

A heat pump’s seasonal heating coefficient of performance is HSPF ÷ 3.412. With HSPF 8.0, that’s a seasonal COP of 2.34 — meaning 2.34 units of heat delivered per 1 unit of electricity consumed. Resistance heating delivers 1-to-1.

For the same 12,000 kWh of heat per year, the heat pump needs 5,118 kWh of electricity; resistance needs 12,000 kWh. Multiplied by Missouri’s residential rate (14.01¢/kWh from the EIA), that’s the costs above.

FAQ

Does a heat pump work in Missouri’s winters?

Missouri's mild winters are ideal for heat pumps — they operate at peak efficiency. Almost any modern model will work well.

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 Missouri, 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.
