HeatPumpPayback

Heat pump vs. gas furnace in Southbridge Town, MA

In Southbridge Town, the extra upfront cost technically comes back, just not before the equipment wears out. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Southbridge Town's residents would see roughly $70 a year back in running costs, putting the payback around 50.1 years. Southbridge Town's own numbers say this pencils out only in theory, not in practice.

The climate behind Southbridge Town's payback figure

Southbridge Town has a cold winter that leans hard on heating equipment — 5603 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 656 cooling degree days. Sizing runs off the design temperature, not the average day: 8.1°F here (record low 3.9°F), which works out to a seasonal COP of 2.89 for the cold-climate class of unit this climate calls for. Below the 25°F line where a standard machine starts leaning on resistance backup, Southbridge Town sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from WORCESTER REGIONAL AIRPORT, the closest NOAA station, 16.8 miles out.

The month-to-month numbers for Southbridge Town

Modelled on a typical 2000-square-foot house, the heat pump draws about 4,909 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,649 a year. The gas furnace it replaces burns roughly 58 Mcf a year at 25.06 per Mcf here, for a running cost near $1,719 a year (electricity here runs 30.15¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is roughly 193.1 years, leaving the 15-year total $2,451 behind.

Electric resistance heat in Southbridge Town, compared

Gas isn't universal in Southbridge 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. Switching saves about $2,885 a year here — a heat pump moving heat rather than generating it needs far less electricity than resistance coils — so the extra $8,000 spent up front comes back in about 2.8 years.

Southbridge Town against the rest of the country

Southbridge Town lands at position 341 out of 3206 cities on heating severity (coldest is 1), and 2085 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
