Heat pump vs gas heating cost in Wyoming

$138 a year saved by heating a typical Wyoming home with a heat pump instead of a gas furnace.

A typical home here burns about 657 therms of gas a year for heat, about $1,117 at the national average of $1.70/therm. A heat pump would use about 6,820 kWh instead, $979 at 14.36¢/kWh. Electricity would have to pass 16.4¢/kWh before gas became the cheaper way to heat.

How Wyoming compares

Ranked by yearly saving against gas, Wyoming is 13th of 51. At U.S. average figures a heat pump saves $27 a year. Wyoming has the 11th cheapest residential electricity of the 50 states and DC, near the middle, at 14.36¢/kWh, 22% below the U.S. average of 18.31¢.

Wyoming is a cold-climate state, with an estimated 7,300 heating degree days a year, so the calculator uses a lower seasonal COP of 2.4. Cold-climate heat pumps rated for low temperatures can do better.

Against propane the heat pump saves $831 a year, against heating oil it saves $1,757 a year, and against electric baseboard heat it saves $1,371 a year.

What these numbers assume

  • A heating load estimated from about 7,300 heating degree days a year: 657 therms of gas, 718 gallons of propane, 504 gallons of oil or 16,367 kWh of baseboard heat.
  • Natural gas at $1.70/therm, the U.S. city average for September 2026. Gas prices vary a lot by state and utility, so enter the price per therm from your bill.
  • Propane at $2.52 and heating oil at $5.43 a gallon, EIA forecasts for winter 2026–27.
  • Furnaces 85% efficient (oil 80%), and a heat pump with a seasonal COP of 2.4.
  • No federal tax credit: Section 25C ended for equipment placed in service after December 31, 2025.
