Heat Pump Payback in West Lafayette, IN
Should West Lafayette switch to a heat pump?
Here in West Lafayette, the honest answer is that a heat pump raises your annual running cost. $5,500 is what West Lafayette would pay extra to go electric rather than replace the furnace and AC with the same again. The heat pump would cost about $167 more a year to run than the furnace it replaces, a premium with no payback. That's West Lafayette's own climate and rates talking, not a hedge or a caveat.

How cold West Lafayette actually gets
Degree days tell the story here: West Lafayette racks up 4684 heating degree days each year (base 65°F), and summers are hot enough that cooling matters as much as heating, with 1024 cooling degree days on the cooling side. Sizing runs off the design temperature, not the average day: -8°F here (coldest 2024 reading -9°F), which works out to a seasonal COP of 2.51 for the cold-climate class of unit this climate calls for. A cold-climate unit is the right call in West Lafayette, 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 Purdue University Airport, the closest NOAA station, 2.3 miles out.
What it actually costs to run, year to year
Electricity use for heating alone comes out to about 4,725 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $953 a year. The gas furnace it replaces burns roughly 49 Mcf a year at $11.49 per Mcf here, for a running cost near $787 a year including the old AC (electricity here runs 17.03¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $8,003 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in West Lafayette
For the verdict in West Lafayette to flip, electricity would need to drop to about 13.1¢/kWh from 17.03¢, or gas climb past $14.91 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 West Lafayette; the case for one here rests on comfort, cooling, or replacing electric heat instead.
Electric resistance heat in West Lafayette, compared
Plenty of homes in West Lafayette heat with electricity alone, no gas line involved. 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 $1,292 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 7.7 years.
West Lafayette against the rest of the country
West Lafayette lands at position 1016 out of 3206 cities on heating severity (coldest is 1), and 884 out of 3206 by population size (biggest is 1). That's the coldest third of the dataset, where climate does most of the work behind this figure.
