🔥 Maine heating

Heat pump or gas furnace in Maine?

At Maine's average electricity rate of 29.6¢/kWh, and US-average gas at $1.50/therm, a typical gas-heated home (600 therms a year) would heat about $1,002 a year cheaper with gas — the heat pump only wins here if your gas is dearer or your power cheaper than average. The tie point is 14.0¢/kWh. Your gas price decides it — put your real one in below.

Why the answer comes out this way in Maine

Maine homes pay about 29.6¢/kWh for electricity — 10.9¢ above the US average. A heat pump delivering COP 2.6 heat ties a 95% furnace when electricity costs 14.0¢/kWh at $1.50/therm gas, so at average prices gas keeps the edge here. Local gas prices vary as much as power prices do, though — the calculator's gas field is the one to get right.

A worked example for Maine

The heat pump would use about 6,425 kWh a year for the same heat. No federal credit applies — the §25C heat-pump credit ended 31 December 2025 — but state and utility rebates may; check DSIRE.

Pair it with solar?

Electrifying your heat makes rooftop solar offset more of your total energy bill — with the honest caveat that panels produce least in the heating months. See whether solar stacks up at all in Maine with our Maine solar payback calculator, or check your EV charging cost too.
