Will a heat pump pay off in Rathdrum, ID?

Rathdrum 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). The heat pump would cost about $250 more a year to run than the furnace it replaces — a premium with no payback. That's Rathdrum's own climate and rates talking, not a hedge or a caveat.

Rathdrum's weather, in the numbers that matter

Rathdrum has a cold winter that leans hard on heating equipment — 6151 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 556 cooling degree days. -7.6°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -15°F on file. Worked through the model, that's a seasonal COP of 2.52 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, Rathdrum sits firmly in cold-climate territory, so that's the class of unit priced here. These numbers come from COEUR D'ALENE AIR TERM APT, the closest NOAA station, 4 miles out.

Rathdrum's running-cost comparison, in dollars

A 2000-square-foot house here would pull roughly 6,181 heating kilowatt-hours annually on top of cooling, totalling about $833 a year on electricity. The gas furnace it replaces burns roughly 64 Mcf a year at 7.69 per Mcf here, for a running cost near $583 a year (electricity here runs 12.52¢/kWh). Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $7,255 behind.

Electric resistance heat in Rathdrum, compared

Plenty of homes in Rathdrum heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Rathdrum's answer improves. The saving here runs about $1,207 a year, which recovers the extra $8,000 spent going electric in roughly 6.6 years.

Rathdrum against the rest of the country

Rathdrum lands at position 174 out of 3206 cities on heating severity (coldest is 1), and 2711 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.
