Gas vs Electric Heating Cost in Missouri
In Missouri, a 2,000 sq ft house with average insulation costs an estimated $1,288.49 a year to heat with a 92% gas furnace, $3,881.97 with electric resistance heat and $1,386.42 with a heat pump. Gas and a heat pump land within about 10% of each other here, $97.93 a year apart, so your own prices decide it.

Worked example
Worked example: 2,000 sq ft in Missouri
A 2,000 sq ft house with average insulation in Missouri needs about 82.3 MMBtu of heat a year (4,900 heating degree-days). At $1.44/therm in a 92% furnace, gas delivers that heat at $15.65 per MMBtu; resistance heat at 16.1¢/kWh costs $47.16, and a heat pump at seasonal COP 2.8 (zone 4) costs $16.84. The year comes to $1,288.49 on gas, $3,881.97 on resistance heat and $1,386.42 on a heat pump. Heat pump and gas are within about 10% here; type your bill's rate and gas price above to see which wins for you.
Load = sq ft × 0.35 × heating degree-days × 24 ÷ 1,000,000. Gas $/MMBtu = $/therm ÷ 0.1 ÷ 0.92. Resistance $/MMBtu = $/kWh × 293.07. Heat pump = resistance ÷ COP.
Questions
FAQ
Which is cheaper in Missouri, gas or electric heat?
Electric resistance heat is the most expensive of the three in Missouri: $3,881.97 a year for the 2,000 sq ft example, $2,593.48 more than gas. Between gas ($1,288.49) and a heat pump ($1,386.42), the cheaper of the two is gas, by $97.93 a year, a margin your own bill's prices can reverse. These are estimates at 16.1¢/kWh and $1.44/therm; your bill's prices can change the answer.
How much gas does a furnace use in Missouri?
About 895 therms a year for a 2,000 sq ft house with average insulation and a 92% furnace, at Missouri's 4,900 heating degree-days. That averages 75 therms a month over 12 months, but almost all of it is burned in the heating months. At $1.44/therm, the year costs an estimated $1,288.49.
Electric furnace vs gas furnace cost in Missouri?
An electric furnace is resistance heat: every kWh gives 3,412 BTU. At 16.1¢/kWh, that heat costs $47.16 per MMBtu in Missouri, against $15.65 from a 92% gas furnace at $1.44/therm, 3.0 times as much. For the 2,000 sq ft example that's $3,881.97 a year against $1,288.49.
