Cost to heat a home in Oregon
Cheapest to run in Oregon is
a heat pump
A heat pump costs about $395 a year less than a gas furnace here. That is a consequence of Oregon's prices, not of the equipment — the same comparison goes the other way in states with cheaper gas.

About the cold
Oregon sees about 60 freezing nights a year. A modern heat pump handles that without much backup heat, so the running costs above are what you would actually see.
Common questions
Is a heat pump cheaper than gas heating in Oregon?
Yes. At Oregon's prices a heat pump costs about $1331 a season against $1726 for a gas furnace — roughly $395 less a year for the same heat.
What does it cost to heat a house in Oregon for a winter?
Between about $1331 and $3317 for a 1,800 square foot home, depending entirely on the system. Oregon runs around 4,600 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 Oregon that difference is about $1986 a season.
