Newburyport, MA: the heat pump payback math
In Newburyport, the extra upfront cost technically comes back, just not before the equipment wears out. Against a like-for-like gas furnace and AC swap, going electric costs $3,500 more up front here (already netting out a $2,000 tax credit). Lower bills claw that back: about $109 saved annually, for a payback of roughly 32.2 years. Newburyport's own numbers say this pencils out only in theory, not in practice.
The climate behind Newburyport's payback figure
Degree days tell the story here: Newburyport racks up 5514 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 759 cooling degree days on the cooling side. 10°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 3.9°F on file. Worked through the model, that's a seasonal COP of 2.94 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Newburyport sits firmly in cold-climate territory, so that's the class of unit priced here.

The month-to-month numbers for Newburyport
Modelled on a typical 2000-square-foot house, the heat pump draws about 4,749 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,627 a year. Newburyport's gas rate of 25.06 per Mcf, applied to the 57 Mcf a year the furnace burns, puts its running cost near $1,736 a year, against 30.15¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to 124.2 years; over 15 years the net position sits $1,869 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Newburyport — many houses run on electric heat already. Swap the comparison to resistance heat instead of gas, and Newburyport's answer improves. About $2,879 a year comes back this way, enough that the 2.8-year payback clears the $8,000 premium comfortably within the equipment's life.
Where Newburyport ranks in this dataset
Ranked against the other 3206 cities covered, Newburyport comes in at 368 for heating severity — 1 would be the coldest place in the dataset — and 1998 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

More on how this number was built
Every constant behind this page — the 2.94 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Newburyport's 10°F design temperature is below the 25°F line, which is why a cold-climate unit is the right call here — see what that changes in the cold-climate unit guide.
