Heat Pump Payback in Chesterton, IN
Heat pump vs. gas furnace in Chesterton, IN
Here in Chesterton, 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 $5,500 more up front here. The heat pump would cost about $109 more a year to run than the furnace it replaces, a premium with no payback. That's Chesterton's own climate and rates talking, not a hedge or a caveat.

Chesterton's weather, in the numbers that matter
Degree days tell the story here: Chesterton racks up 4617 heating degree days each year (base 65°F), and summers add a moderate cooling load, with 859 cooling degree days on the cooling side. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 1.6°F, and the coldest daily reading in the 2024 station record was -7.2°F. That puts the seasonal coefficient of performance at 2.74 for the recommended cold-climate unit. A cold-climate unit is the right call in Chesterton, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings. These numbers come from Burns Harbor, the closest NOAA station, 6 miles out.
The yearly running costs in Chesterton
Electricity use for heating alone comes out to about 4,267 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $851 a year. Chesterton's gas rate of $11.49 per Mcf, applied to the 48 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $742 a year, against 17.03¢ per kWh for electricity. Because the heat pump costs more to run here, the gap only widens with time: $7,139 behind after 15 years compared with replacing the furnace and AC like-for-like.
What would change Chesterton's answer
For the verdict in Chesterton to flip, electricity would need to drop to about 14.2¢/kWh from 17.03¢, or gas climb past $13.76 per Mcf from $11.49. 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 Chesterton; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in Chesterton, compared
Not every home in Chesterton has gas service. Against electric-resistance heat, baseboard or an electric furnace, both 100% efficient but still just resistance, the case for switching gets stronger here. Switching saves about $1,329 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 7.5 years.
Where Chesterton ranks in this dataset
Among 3206 cities, Chesterton's winter puts it at rank 1072 for severity, while its size puts it at rank 2425 for population, 1 in both cases being the extreme. That's the middle third for winter severity among the cities covered here.
