HeatPumpPayback

Will a heat pump pay off in University Place, WA?

This one's marginal in University Place: it only clears if you stay long enough. 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). That premium is recovered through $326 of lower running costs every year, landing the payback clock at roughly 10.7 years. It's a genuine toss-up here — University Place's numbers don't point clearly either way.

University Place's weather, in the numbers that matter

4444 heating degree days pile up here every year, so University Place has a real but manageable winter; the cooling side runs to 243 cooling degree days, where summers rarely ask much of an air conditioner. Sizing runs off the design temperature, not the average day: 19.9°F here (record low 17.1°F), which works out to a seasonal COP of 3.18 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in University Place — below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. Climate figures trace to the nearest NOAA station, TACOMA NARROWS AIRPORT, 3.9 miles from University Place.

The month-to-month numbers for University Place

Electricity use for heating alone comes out to about 3,539 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $535 a year. That compares with roughly 46 Mcf a year of gas at University Place's 17.62 per-Mcf rate — about $860 a year — against a local electricity rate of 14.27¢/kWh. Looked at as a full purchase rather than an incremental one, payback here is roughly 41.4 years, leaving the 15-year total $1,389 ahead.

If your home heats with electric baseboard instead of gas

Plenty of homes in University Place heat with electricity alone, no gas line involved. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,116 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 7.2 years.

University Place against the rest of the country

Among 3206 cities, University Place's winter puts it at rank 1222 for severity, while its size puts it at rank 1168 for population — 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.

What to do with this number in University Place

University Place, Washington is home to about 35,160 people, and the figures above are the same ones a local HVAC contractor uses to size and quote a system — this site doesn't guess where a real quote would land, it just tells you whether it's worth asking for one. In University Place, nothing is lost by holding off until the current equipment genuinely fails.

Every constant behind this page — the 3.18 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. University Place's 19.9°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.
