My father has a heat pump that works fine in alpine climate (half of the winter snow outside) for more than a decade now. Not sure about the precise english terminology here, but his hear pump works using the deep ground water next to our house. The temperature of that water slightly dips in winter, but it is no more than a degree.
It is a very old house that before had a oil heating system and I think the replacement worked quite well.
- sgerenser 3y agoThat’s a ground-source heat pump (often called geothermal heat pump). These have been around for decades in the U.S. but haven’t been very popular due to the 2-3x installed cost vs. an air source heat pump.
- solardev 3y agoThis is common in some parts of the world (which is great!), but not in the US. They're quite a bit more expensive, especially compared to modern mini-split air-source heat pumps that can cost just a couple thousand dollars and don't require any digging or duct installations, just a small hole in the wall.
- atoav 3y agoI guess my father was just lucky, because 1m through the wall from our oil cellar we had an old well that could be used, so there was no need for much more digging (except 1m sidways). He added a ton of solar as well, which is a nice combination.
