How Mississippi compares
Mississippi ranks 46th most expensive of 50 places with a real heating season when each uses its cheapest option, and 46th for a gas furnace. Its gas figure of $505 is 39% below the US average of $831.
The climate explains part of it. Mississippi averages 2,369 heating degree days a year (1991-2020 normal, weighted by where people live), 56% of the contiguous US figure of 4,230, so the same house needs 29.8 million BTU of heat a winter against 53.3 nationally. The rest is prices: electricity at 14.0 cents per kWh against a US average of 17.3, and the fuel prices below.
Is a heat pump worth it in Mississippi?
On running cost alone, an air-source heat pump costs $517 a year here. That is $1,044 a year less than heating oil, $548 less than propane and $710 less than electric baseboards. A gas furnace is still $12 a year cheaper where gas service is available.

Lowering the bill
- A setback schedule on a smart thermostat trims heating energy by about 8% by ENERGY STAR's estimate, about $40 a year on the natural gas furnace figure here.
- A space heater only saves money if the rest of the house is allowed to cool. At 14.0 cents per kWh a 1,500 W heater costs about $0.21 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.

How much does it cost to heat a house in Mississippi?
For a 2,000 sq ft home with average insulation in a normal Mississippi winter: $505 with a natural gas furnace, $517 with an air-source heat pump, $1,065 with a propane furnace, $1,227 with electric resistance heat, $1,561 with a heating oil boiler. That uses EIA prices for Mississippi and its 1991-2020 normal of 2,369 heating degree days.
What is the cheapest way to heat a home in Mississippi?
A natural gas furnace, at about $505 a year for our reference home. The next cheapest is an air-source heat pump at $517, and the most expensive is a heating oil boiler at $1,561. If you have no gas line, the choice is usually between a heat pump, propane and oil.
