Heat Pump Payback in Whitewater, WI
Should Whitewater switch to a heat pump?
Here in Whitewater, the honest answer is that a heat pump raises your annual running cost. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. Unfortunately the electric bill outweighs the gas bill it replaces by about $334 a year here, so the extra spend stays unrecovered. That's Whitewater's own climate and rates talking, not a hedge or a caveat.

How cold Whitewater actually gets
Whitewater has a cold winter that leans hard on heating equipment, 5393 heating degree days a year against a 65°F base, and summers add a moderate cooling load, at 828 cooling degree days. -5.8°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -14.8°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.56 on the cold-climate unit fit for this climate. Whitewater 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. Climate figures trace to the nearest NOAA station, Rock County Airport, 21.5 miles from Whitewater.
The yearly running costs in Whitewater
A 2000-square-foot house here would pull roughly 5,334 heating kilowatt-hours annually on top of cooling, totalling about $1,140 a year on electricity. That compares with roughly 56 Mcf a year of gas at Whitewater's $10.74 per-Mcf rate, about $806 a year with the old AC included, against a local electricity rate of 18.87¢/kWh. Because the heat pump costs more to run here, the gap only widens with time: $10,511 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Whitewater
For the verdict in Whitewater to flip, electricity would need to drop to about 12.1¢/kWh from 18.87¢, or gas climb past $16.69 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 Whitewater; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in Whitewater, compared
Gas isn't universal in Whitewater, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. The saving here runs about $1,640 a year, which recovers the extra $10,000 spent going electric in roughly 6.1 years.
Whitewater against the rest of the country
Ranked against the other 3206 cities covered, Whitewater comes in at 433 for heating severity, 1 would be the coldest place in the dataset, and 2288 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 Whitewater
