Heat pump vs. gas furnace in Newark, DE
Newark technically pencils out, but only past the point the equipment would need replacing anyway. $3,500 is what Newark would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Newark's residents would see roughly $164 a year back in running costs, putting the payback around 21.4 years. Newark's own numbers say this pencils out only in theory, not in practice.
Why Newark's climate drives this number
4086 heating degree days pile up here every year, so Newark has a real but manageable winter; the cooling side runs to 1272 cooling degree days, where summers are hot enough that cooling matters as much as heating. 10°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 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. A cold-climate unit is the right call in Newark — 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, NEW CASTLE COUNTY AIRPORT, 8.1 miles from Newark.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 3,519 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $803 a year. The gas furnace it replaces burns roughly 43 Mcf a year at 15.97 per Mcf here, for a running cost near $967 a year (electricity here runs 17.45¢/kWh). Buy it outright, not incrementally, and payback stretches to 82.4 years; over 15 years the net position sits $1,041 behind.
The other scenario: no gas furnace to begin with
Not every home in Newark has gas service. Swap the comparison to resistance heat instead of gas, and Newark's answer improves. Switching saves about $1,290 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 6.2 years.
Newark against the rest of the country
Among 3206 cities, Newark's winter puts it at rank 1461 for severity, while its size puts it at rank 1337 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

Nothing above is a black box: the methodology guide shows the full arithmetic behind Newark's 2.94 seasonal COP and payback figure. Newark'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.
