Cold-climate heat pumps in Kentucky, and what they cost to run

At Kentucky’s electricity price of 14.26¢ per kilowatt-hour, these are the ENERGY STAR cold-climate heat pumps that keep the most of their heating capacity when it is 5 °F outside — the moment a heat pump either works or does not.

8,791 of 9,168 certified cold-climate models hold at least 70% of their 47 °F capacity at 5 °F. The register publishes this for nearly every model and nobody makes it browsable.

Computed from electricity at 14.26¢/kWh, the EIA average for KY in June 2026 and gas at $33.20/Mcf for June 2026. A kilowatt-hour is 3412 BTU. Gas volume is converted to heat at 1.037 million BTU per thousand cubic feet, EIA's published average. This is a rate times a rating, not a prediction of your bill.
