How Florida compares
Florida ranks 50th most expensive of 50 places with a real heating season when each uses its cheapest option, and 50th for a gas furnace. Its gas figure of $185 is 78% below the US average of $831.
The climate explains part of it. Florida averages 566 heating degree days a year (1991-2020 normal, weighted by where people live), 13% of the contiguous US figure of 4,230, so the same house needs 7.1 million BTU of heat a winter against 53.3 nationally. The rest is prices: electricity at 15.2 cents per kWh against a US average of 17.3, and the fuel prices below.
Is a heat pump worth it in Florida?
On running cost alone, an air-source heat pump costs $134 a year here. That is $225 a year less than heating oil, $269 less than propane and $184 less than electric baseboards. It also beats a gas furnace by $50 a year, so it is the cheapest way to heat in Florida.

Lowering the bill
- A setback schedule on a smart thermostat trims heating energy by about 8% by ENERGY STAR's estimate, about $11 a year on the air-source heat pump figure here.
- A space heater only saves money if the rest of the house is allowed to cool. At 15.2 cents per kWh a 1,500 W heater costs about $0.23 for each hour it runs on high; see what a space heater costs to run.
- Air sealing and attic insulation lower every number on this page in proportion, because they cut the heat the house needs.
Florida heating cost FAQ
How much does it cost to heat a house in Florida?
For a 2,000 sq ft home with average insulation in a normal Florida winter: $134 with an air-source heat pump, $185 with a natural gas furnace, $319 with electric resistance heat, $359 with a heating oil boiler, $403 with a propane furnace. That uses EIA prices for Florida and its 1991-2020 normal of 566 heating degree days.
What is the cheapest way to heat a home in Florida?
An air-source heat pump, at about $134 a year for our reference home. The next cheapest is a natural gas furnace at $185, and the most expensive is a propane furnace at $403. If you have no gas line, the choice is usually between a heat pump, propane and oil.
Is a heat pump cheaper than oil or propane in Florida?
Yes against oil: about $225 a year less. Against propane it saves about $269 a year. That uses a 8.1 HSPF2 heat pump.
How much heating oil or propane does a house in Florida use in a winter?
Our 2,000 sq ft reference home needs about 61 gallons of heating oil in an 85% efficient boiler, or 82 gallons of propane in a 95% furnace, in a normal Florida winter. Smaller or tighter homes use less; a cold winter uses more in proportion.
