Cost to heat a home in Florida
Cheapest to run in Florida is
a heat pump
A heat pump costs about $112 a year less than a gas furnace here. That is a consequence of Florida's prices, not of the equipment — the same comparison goes the other way in states with cheaper gas.

Heating barely matters here
Florida runs only about 700 heating degree days and sees around 5 freezing nights a year. Heating is a small enough share of the bill that the choice of system matters far less than it does further north — cooling is where the money goes.
Common questions
Is a heat pump cheaper than gas heating in Florida?
Yes. At Florida's prices a heat pump costs about $189 a season against $301 for a gas furnace — roughly $112 less a year for the same heat.
What does it cost to heat a house in Florida for a winter?
Between about $189 and $471 for a 1,800 square foot home, depending entirely on the system. Florida runs around 700 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 Florida that difference is about $282 a season.
