Heat Pump Payback in De Pere, WI
Will a heat pump pay off in De Pere, WI?
Here in De Pere, the honest answer is that a heat pump raises your annual running cost. $5,500 is what De Pere would pay extra to go electric rather than replace the furnace and AC with the same again. Running costs here land $366 a year higher than the furnace it replaces, so that premium is never recovered. That's De Pere's own climate and rates talking, not a hedge or a caveat.

De Pere's weather, in the numbers that matter
5968 heating degree days pile up here every year, so De Pere has a cold winter that leans hard on heating equipment; the cooling side runs to 605 cooling degree days, where summers add a moderate cooling load. -2.9°F is the figure equipment gets sized against here, the 99th-percentile cold snap, not an average day, with a low of -9°F in the 2024 station record. Worked through the model, that's a seasonal COP of 2.63 on the cold-climate unit fit for this climate. Below the 25°F line where a standard machine starts leaning on resistance backup, De Pere sits firmly in cold-climate territory, so that's the class of unit priced here.

The yearly running costs in De Pere
Electricity use for heating alone comes out to about 5,746 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,182 a year. De Pere's gas rate of $10.74 per Mcf, applied to the 62 Mcf a year the furnace burns, puts the current furnace-and-AC running cost near $815 a year, against 18.87¢ per kWh for electricity. Because the heat pump costs more to run here, the gap only widens with time: $10,991 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in De Pere
For the verdict in De Pere to flip, electricity would need to drop to about 12.2¢/kWh from 18.87¢, or gas climb past $16.63 per Mcf from $10.74. 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 De Pere; the case for one here rests on comfort, cooling, or replacing electric heat instead.
The other scenario: no gas furnace to begin with
Not every home in De Pere 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 $1,818 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 5.5 years.
