Should Delaware switch to a heat pump?

In Delaware, a heat pump would cost more to run each year than what you have now. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $3,500 after a $2,000 federal tax credit. Running costs here land $34 a year HIGHER than the furnace it replaces, so that premium is never recovered. That's Delaware's own climate and rates talking, not a hedge or a caveat.

How cold Delaware actually gets

5002 heating degree days pile up here every year, so Delaware has a cold winter that leans hard on heating equipment; the cooling side runs to 868 cooling degree days, where summers add a moderate cooling load. 5°F is the figure equipment gets sized against here — the 99th-percentile cold snap, not an average day — with a record low of 1.4°F on file. Worked through the model, that's a seasonal COP of 2.82 on the cold-climate unit fit for this climate. Delaware needs the cold-climate class of unit: past a 25°F design temperature a standard heat pump falls back on resistance backup often enough to eat the savings.

What it actually costs to run, year to year

Electricity use for heating alone comes out to about 4,491 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $963 a year. That compares with roughly 52 Mcf a year of gas at Delaware's 13.85 per-Mcf rate — about $928 a year — against a local electricity rate of 18.40¢/kWh. Buy it outright, not incrementally, and payback stretches to beyond the 15-year equipment life; over 15 years the net position sits $4,012 behind.

Electric resistance heat in Delaware, compared

Plenty of homes in Delaware 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 $1,575 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.

Delaware against the rest of the country

Ranked against the other 3206 cities covered, Delaware comes in at 690 for heating severity — 1 would be the coldest place in the dataset — and 879 by population, where 1 is largest. 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 Delaware

Delaware, Ohio is home to about 46,521 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 Delaware, nothing is lost by holding off until the current equipment genuinely fails.

Where Delaware's figure comes from

Every constant behind this page — the 2.82 seasonal COP, the degree-day corrections, the equipment costs — is documented in the methodology guide. Delaware's 5°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.
