Heat Pump Payback in Shorewood, WI
Should Shorewood switch to a heat pump?
Shorewood is a place where a heat pump genuinely costs more to operate than the alternative. $5,500 is what Shorewood would pay extra to go electric rather than replace the furnace and AC with the same again. Running costs here land $293 a year higher than the furnace it replaces, so that premium is never recovered. That's Shorewood's own climate and rates talking, not a hedge or a caveat.

Shorewood's weather, in the numbers that matter
Shorewood has a cold winter that leans hard on heating equipment, 5284 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 652 cooling degree days. Sizing runs off the design temperature, not the average day: -0.4°F here (coldest 2024 reading -7.1°F), which works out to a seasonal COP of 2.69 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, Shorewood sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, Milwaukee, 2.9 miles from Shorewood.
The yearly running costs in Shorewood
A 2000-square-foot house here would pull roughly 4,974 heating kilowatt-hours annually on top of cooling, totalling about $1,043 a year on electricity. The gas furnace it replaces burns roughly 55 Mcf a year at $10.74 per Mcf here, for a running cost near $750 a year including the old AC (electricity here runs 18.87¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $9,895 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Shorewood's answer
For the verdict in Shorewood to flip, electricity would need to drop to about 12.6¢/kWh from 18.87¢, or gas climb past $16.06 per Mcf from $10.74. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Shorewood; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Gas isn't universal in Shorewood, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $1,641 a year comes back this way, enough that the 6.1-year payback clears the $10,000 premium comfortably within the equipment's life.
Shorewood against the rest of the country
Ranked against the other 3206 cities covered, Shorewood comes in at 507 for heating severity, 1 would be the coldest place in the dataset, and 2584 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.
What to do with this number in Shorewood

Nothing above is a black box: the methodology guide shows the full arithmetic behind Shorewood's 2.69 seasonal COP and payback figure. Shorewood's -0.4°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.
