Heat pump vs gas heating cost in Colorado

$101 a year saved by heating a typical Colorado home with a heat pump instead of a gas furnace.

A typical home here burns about 540 therms of gas a year for heat, about $918 at the national average of $1.70/therm. A heat pump would use about 4,804 kWh instead, $817 at 17.00¢/kWh. Electricity would have to pass 19.1¢/kWh before gas became the cheaper way to heat.

What these numbers assume

  • A heating load estimated from about 6,000 heating degree days a year: 540 therms of gas, 590 gallons of propane, 414 gallons of oil or 13,453 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 2.8.
  • No federal tax credit: Section 25C ended for equipment placed in service after December 31, 2025.
