Heat Pump Payback in Bayonne, NJ
Should Bayonne switch to a heat pump?
Bayonne is a place where a heat pump genuinely costs more to operate than the alternative. Swap a failed furnace and AC for a heat pump rather than buying like-for-like, and the extra cost here runs $5,500. The heat pump would cost about $54 more a year to run than the furnace it replaces, a premium with no payback. That's Bayonne's own climate and rates talking, not a hedge or a caveat.

Bayonne's weather, in the numbers that matter
Degree days tell the story here: Bayonne racks up 4067 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1039 cooling degree days on the cooling side. 18.5°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of 12.7°F in the 2024 station record. Worked through the model, that's a seasonal COP of 3.14 on the cold-climate unit fit for this climate. Bayonne 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.

Bayonne's running-cost comparison, in dollars
A 2000-square-foot house here would pull roughly 3,280 heating kilowatt-hours annually on top of cooling, totalling about $970 a year on electricity. The gas furnace it replaces burns roughly 42 Mcf a year at $14.21 per Mcf here, for a running cost near $915 a year including the old AC (electricity here runs 23.28¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $6,316 behind after 15 years compared with replacing the furnace and AC like-for-like.
How sensitive Bayonne's result is to prices
For the verdict in Bayonne to flip, electricity would need to drop to about 21.4¢/kWh from 23.28¢, or gas climb past $15.49 per Mcf from $14.21. A utility offering a lower heat pump rate can change this. Until then, no quote price makes a heat pump pay back against gas in Bayonne; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Plenty of homes in Bayonne heat with electricity alone, no gas line involved. Swap the comparison to resistance heat instead of gas, and Bayonne's answer improves. Switching saves about $1,741 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 5.7 years.
Bayonne against the rest of the country
Bayonne lands at position 1479 out of 3206 cities on heating severity (coldest is 1), and 517 out of 3206 by population size (biggest is 1). That's the middle third for winter severity among the cities covered here.
