Do you use it as part of a geothermal system, or are you talking about extracting the heat from the air?
My thermodynamics class is some time ago, but pumping the heat stored in arctic air to a sufficiently high level for residential heating sounds indeed like an electric heating effectively.
- geon 3y agoYes, when you get down to -20 C or so, the efficiency drops below 1. Depending on the model. I think air heat pumps are more common due to their low price. They are easy to install and work well as a complement to other heat sources. Geothermal is popular too, but the installation cost is significantly higher.
