They are in the north. Heat pumps are worthless below a certain point. I think around 10-20F.

- ericd 5y agoI’m guessing in-ground heat pumps with their heat exchanger liquid lines below the frost line still work…
- flyingfences 5y agoGround-source heat pumps take advantage of the fact that the earth stays at reasonable temperatures below the frost line.
- jacquesm 5y agoThey work just fine, you're just going to go a bit deeper then. I put a thermal sensor down an old well head in mid winter, it was -20 Celsius at the surface and a 'balmy' 12 degrees at 10 meters down. That gradient will allow you to do a lot of good stuff if you use a freeze proof working fluid for your heatpump.
