HeatPumpPayback

Will a heat pump pay off in New Providence, NJ?

Here in New Providence, the honest answer is that a heat pump raises your annual running cost. 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). The heat pump would cost about $139 more a year to run than the furnace it replaces — a premium with no payback. That's New Providence's own climate and rates talking, not a hedge or a caveat.

How cold New Providence actually gets

4806 heating degree days pile up here every year, so New Providence has a real but manageable winter; the cooling side runs to 942 cooling degree days, where summers add a moderate cooling load. The 99% winter design temperature here — the cold snap equipment must be sized for, not the seasonal average — is 12.2°F, against a record low of 6.8°F. That puts the seasonal coefficient of performance at 2.99 for the recommended cold-climate unit. Below the 25°F line where a standard machine starts leaning on resistance backup, New Providence sits firmly in cold-climate territory, so that's the class of unit priced here.

New Providence's running-cost comparison, in dollars

Electricity use for heating alone comes out to about 4,070 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,134 a year. The gas furnace it replaces burns roughly 50 Mcf a year at 14.21 per Mcf here, for a running cost near $995 a year (electricity here runs 23.28¢/kWh). Looked at as a full purchase rather than an incremental one, payback here is longer than the 15-year equipment life, leaving the 15-year total $5,585 behind.

The other scenario: no gas furnace to begin with

Not every home in New Providence has gas service. Swap the comparison to resistance heat instead of gas, and New Providence's answer improves. Switching saves about $1,983 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 4 years.

How New Providence compares nationally

Among 3206 cities, New Providence's winter puts it at rank 946 for severity, while its size puts it at rank 2518 for population — 1 in both cases being the extreme. That's the coldest third of the dataset, where climate does most of the work behind this figure.
