Should Weymouth Town switch to a heat pump?
Weymouth Town technically pencils out, but only past the point the equipment would need replacing anyway. 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. Weymouth Town's residents would see roughly $157 a year back in running costs, putting the payback around 22.2 years. Weymouth Town's own numbers say this pencils out only in theory, not in practice.
The climate behind Weymouth Town's payback figure
5029 heating degree days pile up here every year, so Weymouth Town has a cold winter that leans hard on heating equipment; the cooling side runs to 807 cooling degree days, where summers add a moderate cooling load. Sizing runs off the design temperature, not the average day: 14°F here (record low 10°F), which works out to a seasonal COP of 3.04 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, Weymouth Town sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, GEN E L LOGAN INTERNATIONAL A, 11.1 miles from Weymouth Town.
Weymouth Town's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 4,189 heating kilowatt-hours annually on top of cooling, totalling about $1,470 a year on electricity. That compares with roughly 52 Mcf a year of gas at Weymouth Town's 25.06 per-Mcf rate — about $1,628 a year — against a local electricity rate of 30.15¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 85.7 years, leaving the 15-year total $1,138 behind.
If your home heats with electric baseboard instead of gas
Not every home in Weymouth Town has gas service. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. About $2,684 a year comes back this way, enough that the 3-year payback clears the $8,000 premium comfortably within the equipment's life.
Weymouth Town against the rest of the country
Among 3206 cities, Weymouth Town's winter puts it at rank 662 for severity, while its size puts it at rank 667 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where Weymouth Town's figure comes from
Every constant behind this page — the 3.04 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Weymouth Town's 14°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
