Heat Pump Payback in Stillwater, MN
Is a heat pump worth it in Stillwater?
In Stillwater, a heat pump would cost more to run each year than what you have now. 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 $184 more a year to run than the furnace it replaces, a premium with no payback. That's Stillwater's own climate and rates talking, not a hedge or a caveat.

How cold Stillwater actually gets
5994 heating degree days pile up here every year, so Stillwater has a cold winter that leans hard on heating equipment; the cooling side runs to 749 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 -5.1°F, and the coldest daily reading in the 2024 station record was -8°F. That puts the seasonal coefficient of performance at 2.58 for the recommended cold-climate unit. A cold-climate unit is the right call in Stillwater, below 25°F design temperature, a standard heat pump leans hard on electric-resistance backup, which erases most of the savings.

Stillwater's running-cost comparison, in dollars
Electricity use for heating alone comes out to about 5,883 kWh a year on the 2000-square-foot reference house; folding in cooling puts the electric bill near $1,022 a year. The gas furnace it replaces burns roughly 62 Mcf a year at $10.98 per Mcf here, for a running cost near $838 a year including the old AC (electricity here runs 15.67¢/kWh). Because the heat pump costs more to run here, the gap only widens with time: $8,265 behind after 15 years compared with replacing the furnace and AC like-for-like.
The break-even point in Stillwater
For the verdict in Stillwater to flip, electricity would need to drop to about 12.3¢/kWh from 15.67¢, or gas climb past $13.93 per Mcf from $10.98. 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 Stillwater; 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 Stillwater 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. About $1,509 a year comes back this way, enough that the 6.6-year payback clears the $10,000 premium comfortably within the equipment's life.
Where Stillwater ranks in this dataset
Stillwater lands at position 237 out of 3206 cities on heating severity (coldest is 1), and 1982 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.
