Heat pump vs gas heating cost in Oklahoma

$178 a year saved by heating a typical Oklahoma home with a heat pump instead of a gas furnace.

A typical home here burns about 306 therms of gas a year for heat, about $520 at the national average of $1.70/therm. A heat pump would use about 2,382 kWh instead, $342 at 14.35¢/kWh. Electricity would have to pass 21.8¢/kWh before gas became the cheaper way to heat.

How Oklahoma compares

Ranked by yearly saving against gas, Oklahoma is 8th of 51. At U.S. average figures a heat pump saves $27 a year. Oklahoma has the 10th cheapest residential electricity of the 50 states and DC at 14.35¢/kWh, 22% below the U.S. average of 18.31¢.

Winters here are mild, with an estimated 3,400 heating degree days a year, so the calculator uses a seasonal COP of 3.2: each kWh of electricity delivers 3.2 kWh of heat.

Against propane the heat pump saves $502 a year, against heating oil it saves $934 a year, and against electric baseboard heat it saves $752 a year.

What these numbers assume

  • A heating load estimated from about 3,400 heating degree days a year: 306 therms of gas, 335 gallons of propane, 235 gallons of oil or 7,623 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 3.2.
  • No federal tax credit: Section 25C ended for equipment placed in service after December 31, 2025.
