Is a heat pump worth it in St. Clair Shores?

In St. Clair Shores, a heat pump would cost more to run each year than what you have now. 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 $270 a year here, so the extra spend stays unrecovered. That's St. Clair Shores's own climate and rates talking, not a hedge or a caveat.

How cold St. Clair Shores actually gets

St. Clair Shores has a real but manageable winter — 4925 heating degree days a year against a 65°F base — and summers add a moderate cooling load, at 868 cooling degree days. 5.7°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of -0.9°F on file. Worked through the model, that's a seasonal COP of 2.84 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, St. Clair Shores sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, ST CLAIR SHORES, 2.2 miles from St. Clair Shores.

The month-to-month numbers for St. Clair Shores

Electricity use for heating alone comes out to about 4,391 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,063 a year. St. Clair Shores's gas rate of 10.92 per Mcf, applied to the 51 Mcf a year the furnace burns, puts its running cost near $793 a year, against 20.72¢ per kWh for electricity. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $7,550 behind.

The other scenario: no gas furnace to begin with

Plenty of homes in St. Clair Shores 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. The saving here runs about $1,754 a year, which recovers the extra $8,000 spent going electric in roughly 4.6 years.

St. Clair Shores against the rest of the country

Ranked against the other 3206 cities covered, St. Clair Shores comes in at 834 for heating severity — 1 would be the coldest place in the dataset — and 704 by population, where 1 is largest. That's the coldest third of the dataset, where climate does most of the work behind this figure.

Where St. Clair Shores's figure comes from

Every constant behind this page — the 2.84 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. St. Clair Shores's 5.7°F design temperature falls on the cold side of the 25°F cutoff the cold-climate unit guide walks through.
