Heat Pump Payback in Gloucester City, NJ
Gloucester City, NJ: the heat pump payback math
Here in Gloucester City, the honest answer is that a heat pump raises your annual running cost. $5,500 is what Gloucester City would pay extra to go electric rather than replace the furnace and AC with the same again. Unfortunately the electric bill outweighs the gas bill it replaces by about $16 a year here, so the extra spend stays unrecovered. There's no spin on that: Gloucester City's numbers say wait.

Why Gloucester City's climate drives this number
Gloucester City has a real but manageable winter, 3829 heating degree days a year against a 65°F base, and summers are hot enough that cooling matters as much as heating, at 1547 cooling degree days. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 14°F, and the coldest daily reading in the 2024 station record was 10.9°F. That puts the seasonal coefficient of performance at 3.04 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, Gloucester City sits firmly in cold-climate territory, so that's the class of unit priced here. Climate figures trace to the nearest NOAA station, Philadelphia International Ai, 6 miles from Gloucester City.
The yearly running costs in Gloucester City
Modelled on a typical 2000-square-foot house, the heat pump draws about 3,189 kWh a year to keep it warm, plus cooling, for a combined electric bill near $1,050 a year. Gloucester City's gas rate of $14.21 per Mcf, applied to the 40 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $1,033 a year, against 23.28¢ per kWh for electricity. With running costs higher every year, there is no payback at any purchase price; over 15 years, against a like-for-like replacement, a household here would end $5,742 behind.
How sensitive Gloucester City's result is to prices
The heat pump would become the cheaper option in Gloucester City if electricity fell to 22.6¢/kWh (from 23.28¢) or gas rose above $14.61 per Mcf (from $14.21). At today's prices a cheaper quote cannot rescue the gas comparison in Gloucester City, since there is no yearly saving to recover it from.
If your home heats with electric baseboard instead of gas
Gas isn't universal in Gloucester City, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. Switching saves about $1,674 a year here, a heat pump moving heat rather than generating it needs far less electricity than resistance coils, so the extra $10,000 spent up front comes back in about 6 years.
How Gloucester City compares nationally
Gloucester City lands at position 1624 out of 3206 cities on heating severity (coldest is 1), and 2875 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.

Where Gloucester City's figure comes from
Every constant behind this page, the 3.04 seasonal COP, the degree-day corrections, the equipment costs, is documented in the methodology guide.
