Heat pump vs. gas furnace in Glassboro, NJ

Glassboro is a place where a heat pump genuinely costs more to operate than the alternative. $3,500 is what Glassboro would pay extra to go electric rather than replace the furnace and AC with the same again, once the $2,000 federal credit is applied. Unfortunately the electric bill outweighs the gas bill it replaces by about $16 a year here, so the extra spend stays unrecovered. That's Glassboro's own climate and rates talking, not a hedge or a caveat.

Glassboro's weather, in the numbers that matter

3829 heating degree days pile up here every year, so Glassboro has a real but manageable winter; the cooling side runs to 1547 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 14°F, against a record low of 10.9°F. That puts the seasonal coefficient of performance at 3.04 for the recommended cold-climate unit. A cold-climate unit is the right call in Glassboro — 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, PHILADELPHIA INTERNATIONAL AI, 13.4 miles from Glassboro.

What it actually costs to run, year to year

Electricity use for heating alone comes out to about 3,189 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,050 a year. The gas furnace it replaces burns roughly 40 Mcf a year at 14.21 per Mcf here, for a running cost near $1,033 a year (electricity here runs 23.28¢/kWh). Priced as a standalone purchase rather than against a like-for-like replacement, equipment payback runs past the 15-year equipment life, for a 15-year net position $3,742 behind.

If your home heats with electric baseboard instead of gas

Plenty of homes in Glassboro heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Glassboro's answer improves. The saving here runs about $1,674 a year, which recovers the extra $8,000 spent going electric in roughly 4.8 years.

Glassboro against the rest of the country

Ranked against the other 3206 cities covered, Glassboro comes in at 1622 for heating severity — 1 would be the coldest place in the dataset — and 1648 by population, where 1 is largest. That's the middle third for winter severity among the cities covered here.
