Anyone seen or heard of cold weather heat pumps working with an Airstream? |
Nope. They "pull heat" from the outside air. Residential heat pumps have an electric heat strip as a backup. Some of the AS's can be ordered with a heat strip. My thermostat automaticly switches over from Heat pump to Furnace around 45.
