Willoughby, OH: the heat pump payback math
Here in Willoughby, the honest answer is that a heat pump raises your annual running cost. $3,500 is what Willoughby 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. The heat pump would cost about $14 more a year to run than the furnace it replaces — a premium with no payback. There's no spin on that: Willoughby's numbers say wait.
Why Willoughby's climate drives this number
Degree days tell the story here: Willoughby racks up 4809 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 727 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: 9°F here (record low 4.5°F), which works out to a seasonal COP of 2.92 for the cold-climate class of unit this climate calls for. Willoughby 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 WILLOUGHBY, the closest NOAA station, 2.7 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 4,170 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $881 a year. The gas furnace it replaces burns roughly 50 Mcf a year at 13.85 per Mcf here, for a running cost near $867 a year (electricity here runs 18.40¢/kWh). Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $3,715 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Willoughby — 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 $1,533 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 5.2 years.
Willoughby against the rest of the country
Ranked against the other 3206 cities covered, Willoughby comes in at 937 for heating severity — 1 would be the coldest place in the dataset — and 1654 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
