Is a heat pump worth it in West Valley City?
In West Valley City, the extra upfront cost technically comes back, just not before the equipment wears out. 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). West Valley City's residents would see roughly $110 a year back in running costs, putting the payback around 31.9 years. That's a technicality, not a recommendation, for anyone actually living in West Valley City.
How cold West Valley City actually gets
Degree days tell the story here: West Valley City racks up 4667 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1804 cooling degree days on the cooling side. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 19°F, against a record low of 12.2°F. That puts the seasonal coefficient of performance at 3.16 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, West Valley City sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, SALT LAKE CITY INTERNATIONAL, 6.6 miles from West Valley City.
The month-to-month numbers for West Valley City
Electricity use for heating alone comes out to about 3,740 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $692 a year. That compares with roughly 49 Mcf a year of gas at West Valley City's 10.19 per-Mcf rate — about $802 a year — against a local electricity rate of 13.12¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 123.2 years, leaving the 15-year total $1,856 behind.
The other scenario: no gas furnace to begin with
Plenty of homes in West Valley City heat with electricity alone, no gas line involved. 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 $1,165 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 6.9 years.
How West Valley City compares nationally
Among 3206 cities, West Valley City's winter puts it at rank 1021 for severity, while its size puts it at rank 206 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.
