Heat pump vs. gas furnace in Salem Lakes, WI
Salem Lakes is a place where a heat pump genuinely costs more to operate than the alternative. 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). Unfortunately the electric bill outweighs the gas bill it replaces by about $256 a year here, so the extra spend stays unrecovered. There's no spin on that: Salem Lakes's numbers say wait.
The climate behind Salem Lakes's payback figure
Degree days tell the story here: Salem Lakes racks up 5018 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 920 cooling degree days on the cooling side. -0.9°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -11°F on file. Worked through the model, that's a seasonal COP of 2.68 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Salem Lakes sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, KENOSHA REGIONAL AIRPORT, 10.7 miles from Salem Lakes.
The month-to-month numbers for Salem Lakes
Electricity use for heating alone comes out to about 4,741 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,043 a year. The gas furnace it replaces burns roughly 52 Mcf a year at 10.74 per Mcf here, for a running cost near $786 a year (electricity here runs 18.87¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $7,346 behind.
The other scenario: no gas furnace to begin with
Gas isn't universal in Salem Lakes — many houses run on electric heat already. Against electric-resistance heat — baseboard or an electric furnace, both 100% efficient but still just resistance — the case for switching gets stronger here. Switching saves about $1,580 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 5.1 years.
How Salem Lakes compares nationally
Salem Lakes lands at position 677 out of 3206 cities on heating severity (coldest is 1), and 2476 out of 3206 by population size (biggest is 1). 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 Salem Lakes
About 14,302 people live in Salem Lakes, Wisconsin, and every number on this page is what a contractor would actually work from when quoting a system here — the point isn't to replace that quote, it's to tell you whether to bother asking for one. Here, there's no cost penalty to waiting until your current furnace or AC actually needs replacing.
Ask a local HVAC contractor for a quote before committing either way.
More on how this number was built
The methodology guide walks through exactly how Salem Lakes's 2.68 seasonal COP and the rest of this page's numbers get built. Salem Lakes's -0.9°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
