Worked example

Worked example: 2,000 sq ft in Pennsylvania

A 2,000 sq ft house with average insulation in Pennsylvania needs about 94.1 MMBtu of heat a year (5,600 heating degree-days). At $1.45/therm in a 92% furnace, gas delivers that heat at $15.76 per MMBtu; resistance heat at 21.7¢/kWh costs $63.66, and a heat pump at seasonal COP 2.5 (zone 5) costs $25.46. The year comes to $1,482.78 on gas, $5,988.91 on resistance heat and $2,395.57 on a heat pump. A heat pump would need electricity near 13.4¢/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 Pennsylvania, gas or electric heat?

Electric resistance heat is the most expensive of the three in Pennsylvania: $5,988.91 a year for the 2,000 sq ft example, $4,506.13 more than gas. Between gas ($1,482.78) and a heat pump ($2,395.57), gas costs less to run in Pennsylvania, by an estimated $912.78 a year. These are estimates at 21.7¢/kWh and $1.45/therm; your bill's prices can change the answer.

How much gas does a furnace use in Pennsylvania?

About 1,023 therms a year for a 2,000 sq ft house with average insulation and a 92% furnace, at Pennsylvania's 5,600 heating degree-days. That averages 85 therms a month over 12 months, but almost all of it is burned in the heating months. At $1.45/therm, the year costs an estimated $1,482.78.

Electric furnace vs gas furnace cost in Pennsylvania?

An electric furnace is resistance heat: every kWh gives 3,412 BTU. At 21.7¢/kWh, that heat costs $63.66 per MMBtu in Pennsylvania, against $15.76 from a 92% gas furnace at $1.45/therm, 4.0 times as much. For the 2,000 sq ft example that's $5,988.91 a year against $1,482.78.
