Heat Pump Payback in Bridgewater Town, MA
Is a heat pump worth it in Bridgewater Town?
The payback math works in Bridgewater Town on paper, past the equipment's own working life. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Lower bills claw that back: about $129 saved annually, for a payback of roughly 42.7 years. Bridgewater Town's own numbers say this pencils out only in theory, not in practice.

The climate behind Bridgewater Town's payback figure
4998 heating degree days pile up here every year, so Bridgewater Town has a real but manageable winter; the cooling side runs to 849 cooling degree days, where summers add a moderate cooling load. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 10.9°F, and the coldest daily reading in the 2024 station record was 6.1°F. That puts the seasonal coefficient of performance at 2.96 for the recommended cold-climate unit. A cold-climate unit is the right call in Bridgewater Town, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, Taunton Municipal Airport, 7 miles from Bridgewater Town.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,276 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,507 a year. The gas furnace it replaces burns roughly 52 Mcf a year at $25.06 per Mcf here, for a running cost near $1,636 a year including the old AC (electricity here runs 30.15¢/kWh). Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $3,567 behind.
The break-even point in Bridgewater Town
This result holds unless electricity climbs above 33.5¢/kWh (it is 30.15¢ now) or gas drops below $22.58 per Mcf (now $25.06); past either point, gas becomes the cheaper fuel in Bridgewater Town. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $129 a year saved, a difference under $903 pays back within 7 years here, and under $1,290 within 10.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Bridgewater Town, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $2,640 a year, which recovers the extra $10,000 spent going electric in roughly 3.8 years.
