Cold-climate heat pumps in Maryland, and what they cost to run
At Maryland’s electricity price of 21.84¢ 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 21.84¢/kWh, the EIA average for MD in June 2026 and gas at $22.57/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.
