Cost to heat a home in Colorado
Cheapest to run in Colorado is
a heat pump
A heat pump costs about $106 a year less than a gas furnace here. That is a consequence of Colorado's prices, not of the equipment — the same comparison goes the other way in states with cheaper gas.

About the cold
Colorado sees about 150 freezing nights a year. That is enough that a heat pump needs to be a cold-climate model, and backup heat will run on the worst nights — which is already reflected in the figures above.
Common questions
Is a heat pump cheaper than gas heating in Colorado?
Yes. At Colorado's prices a heat pump costs about $1814 a season against $1920 for a gas furnace — roughly $106 less a year for the same heat.
What does it cost to heat a house in Colorado for a winter?
Between about $1814 and $4520 for a 1,800 square foot home, depending entirely on the system. Colorado runs around 6,000 heating degree days a year.
Why is electric resistance heat so much more expensive?
It converts electricity to heat one for one, while a heat pump moves heat rather than making it and delivers two to three times as much per unit of electricity. In Colorado that difference is about $2706 a season.
