Heat pump vs. gas furnace in Malden, MA
Malden 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. Lower bills claw that back: about $157 saved annually, for a payback of roughly 22.2 years. Malden's own numbers say this pencils out only in theory, not in practice.
Why Malden's climate drives this number
Degree days tell the story here: Malden racks up 5029 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 807 cooling degree days on the cooling side. 14°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 10°F on file. Worked through the model, that's a seasonal COP of 3.04 on the cold-climate unit fit for this climate. Malden needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings. These numbers come from GEN E L LOGAN INTERNATIONAL A, the closest NOAA station, 5.3 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 4,189 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,470 a year. The gas furnace it replaces burns roughly 52 Mcf a year at 25.06 per Mcf here, for a running cost near $1,628 a year (electricity here runs 30.15¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs about 85.7 years, for a 15-year net position $1,138 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Malden — 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 $2,684 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 3 years.
Where Malden ranks in this dataset
Ranked against the other 3206 cities covered, Malden comes in at 660 for heating severity — 1 would be the coldest place in the dataset — and 588 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where Malden's figure comes from
Nothing above is a black box: the methodology guide shows the full arithmetic behind Malden's 3.04 seasonal COP and payback figure. Malden's 14°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
