Gas vs Electric Heating Cost in Massachusetts
In Massachusetts, a 2,000 sq ft house with average insulation costs an estimated $2,563.10 a year to heat with a 92% gas furnace, $8,707.34 with electric resistance heat and $3,482.94 with a heat pump. In Massachusetts, the gas furnace beats the heat pump on running cost by an estimated $919.84 a year.

Worked example
Worked example: 2,000 sq ft in Massachusetts
A 2,000 sq ft house with average insulation in Massachusetts needs about 97.4 MMBtu of heat a year (5,800 heating degree-days). At $2.42/therm in a 92% furnace, gas delivers that heat at $26.30 per MMBtu; resistance heat at 30.5¢/kWh costs $89.36, and a heat pump at seasonal COP 2.5 (zone 5) costs $35.74. The year comes to $2,563.10 on gas, $8,707.34 on resistance heat and $3,482.94 on a heat pump. A heat pump would need electricity near 22.4¢/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 Massachusetts, gas or electric heat?
Electric resistance heat is the most expensive of the three in Massachusetts: $8,707.34 a year for the 2,000 sq ft example, $6,144.25 more than gas. Between gas ($2,563.10) and a heat pump ($3,482.94), gas costs less to run in Massachusetts, by an estimated $919.84 a year. These are estimates at 30.5¢/kWh and $2.42/therm; your bill's prices can change the answer.
How much gas does a furnace use in Massachusetts?
About 1,059 therms a year for a 2,000 sq ft house with average insulation and a 92% furnace, at Massachusetts's 5,800 heating degree-days. That averages 88 therms a month over 12 months, but almost all of it is burned in the heating months. At $2.42/therm, the year costs an estimated $2,563.10.
Electric furnace vs gas furnace cost in Massachusetts?
An electric furnace is resistance heat: every kWh gives 3,412 BTU. At 30.5¢/kWh, that heat costs $89.36 per MMBtu in Massachusetts, against $26.30 from a 92% gas furnace at $2.42/therm, 3.4 times as much. For the 2,000 sq ft example that's $8,707.34 a year against $2,563.10.
