Heat Pump Payback in Kennett, MO
Should Kennett switch to a heat pump?
The payback math works in Kennett on paper, past the equipment's own working life. Against a like-for-like gas furnace and AC swap, going electric costs $5,500 more up front here. Lower bills claw that back: about $235 saved annually, for a payback of roughly 23.4 years. Kennett's own numbers say this pencils out only in theory, not in practice.

The climate behind Kennett's payback figure
2774 heating degree days pile up here every year, so Kennett has a mild winter by US standards; the cooling side runs to 1986 cooling degree days, where summers are hot enough that cooling matters as much as heating. The 99% winter design temperature here, the cold snap equipment must be sized for, not the seasonal average, is 8.6°F, and the coldest daily reading in the 2024 station record was 5°F. That puts the seasonal coefficient of performance at 2.91 for the recommended cold-climate unit. The average winter here is gentle, but sizing follows the cold snaps, and 8.6°F is below the 25°F point where a standard unit leans on resistance backup, so a cold-climate unit is what gets priced for Kennett. These numbers come from Kennett Mem, the closest NOAA station, 1.1 miles out.
What it actually costs to run, year to year
Modelled on a typical 2000-square-foot house, the heat pump draws about 2,414 kWh a year to keep it warm, plus cooling, for a combined electric bill near $527 a year. The gas furnace it replaces burns roughly 29 Mcf a year at $14.94 per Mcf here, for a running cost near $762 a year including the old AC (electricity here runs 12.83¢/kWh). Buying outright rather than at replacement time stretches payback to longer than the 15-year equipment life. Over 15 years, compared with a like-for-like replacement, the heat pump leaves you $1,976 behind.
The break-even point in Kennett
This result holds unless electricity climbs above 28.2¢/kWh (it is 12.83¢ now) or gas drops below $6.81 per Mcf (now $14.94); past either point, gas becomes the cheaper fuel in Kennett. When quotes arrive, compare the heat pump price with a like-for-like furnace and AC replacement: at $235 a year saved, a difference under $1,645 pays back within 7 years here, and under $2,350 within 10.
Electric resistance heat in Kennett, compared
Gas isn't universal in Kennett, many houses run on electric heat already. Compared with baseboard or electric-furnace resistance heat, the numbers shift in the heat pump’s favor. About $704 a year comes back this way, enough that the 14.2-year payback clears the $10,000 premium comfortably within the equipment's life.
