Gas vs Electric Heating Cost in Indiana
In Indiana, a 2,000 sq ft house with average insulation costs an estimated $1,114.83 a year to heat with a 92% gas furnace, $4,530.63 with electric resistance heat and $1,812.25 with a heat pump. Gas heat costs $12.07 per MMBtu here, against $19.61 from a heat pump at seasonal COP 2.5.

Worked example
Worked example: 2,000 sq ft in Indiana
A 2,000 sq ft house with average insulation in Indiana needs about 92.4 MMBtu of heat a year (5,500 heating degree-days). At $1.11/therm in a 92% furnace, gas delivers that heat at $12.07 per MMBtu; resistance heat at 16.7¢/kWh costs $49.03, and a heat pump at seasonal COP 2.5 (zone 5) costs $19.61. The year comes to $1,114.83 on gas, $4,530.63 on resistance heat and $1,812.25 on a heat pump. A heat pump would need electricity near 10.3¢/kWh to match gas here.
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 Indiana, gas or electric heat?
Electric resistance heat is the most expensive of the three in Indiana: $4,530.63 a year for the 2,000 sq ft example, $3,415.81 more than gas. Between gas ($1,114.83) and a heat pump ($1,812.25), gas costs less to run in Indiana, by an estimated $697.43 a year. These are estimates at 16.7¢/kWh and $1.11/therm; your bill's prices can change the answer.
How much gas does a furnace use in Indiana?
About 1,004 therms a year for a 2,000 sq ft house with average insulation and a 92% furnace, at Indiana's 5,500 heating degree-days. That averages 84 therms a month over 12 months, but almost all of it is burned in the heating months. At $1.11/therm, the year costs an estimated $1,114.83.
Electric furnace vs gas furnace cost in Indiana?
An electric furnace is resistance heat: every kWh gives 3,412 BTU. At 16.7¢/kWh, that heat costs $49.03 per MMBtu in Indiana, against $12.07 from a 92% gas furnace at $1.11/therm, 4.1 times as much. For the 2,000 sq ft example that's $4,530.63 a year against $1,114.83.
