Gas vs Electric Heating Cost in New Hampshire
In New Hampshire, a 2,000 sq ft house with average insulation costs an estimated $2,386.15 a year to heat with a 92% gas furnace, $9,561.03 with electric resistance heat and $4,156.97 with a heat pump. In New Hampshire, the gas furnace beats the heat pump on running cost by an estimated $1,770.82 a year.

Worked example
Worked example: 2,000 sq ft in New Hampshire
A 2,000 sq ft house with average insulation in New Hampshire needs about 122.6 MMBtu of heat a year (7,300 heating degree-days). At $1.79/therm in a 92% furnace, gas delivers that heat at $19.46 per MMBtu; resistance heat at 26.6¢/kWh costs $77.96, and a heat pump at seasonal COP 2.3 (zone 6) costs $33.90. The year comes to $2,386.15 on gas, $9,561.03 on resistance heat and $4,156.97 on a heat pump. At seasonal COP 2.3, the heat pump's heat still costs more than $1.79/therm gas in New Hampshire.
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 New Hampshire, gas or electric heat?
Electric resistance heat is the most expensive of the three in New Hampshire: $9,561.03 a year for the 2,000 sq ft example, $7,174.88 more than gas. Between gas ($2,386.15) and a heat pump ($4,156.97), gas comes out $1,770.82 a year ahead; a heat pump would match it at about 15.3¢/kWh. These are estimates at 26.6¢/kWh and $1.79/therm; your bill's prices can change the answer.
How much gas does a furnace use in New Hampshire?
About 1,333 therms a year for a 2,000 sq ft house with average insulation and a 92% furnace, at New Hampshire's 7,300 heating degree-days. That averages 111 therms a month over 12 months, but almost all of it is burned in the heating months. At $1.79/therm, the year costs an estimated $2,386.15.
Electric furnace vs gas furnace cost in New Hampshire?
An electric furnace is resistance heat: every kWh gives 3,412 BTU. At 26.6¢/kWh, that heat costs $77.96 per MMBtu in New Hampshire, against $19.46 from a 92% gas furnace at $1.79/therm, 4.0 times as much. For the 2,000 sq ft example that's $9,561.03 a year against $2,386.15.
