Ground source heat pumps are 2-3x the cost of air source, and require a decent sized piece of land for installing the ground loop. Vertical installations use less surface area but are even more expensive since you’re drilling holes 400’ deep for the loop.
Water source heat pumps are easier installations but require houses sited near a specific type of fresh water source that does not fully ice over in the winter or dry up in the summer.
- hinkley 4y agoAny studies in what these things do to the frostline? Heat pump is better than burning fossil fuels, but we also stop needing to treat system after system like it’s a bottomless well. We did that with real wells, then rivers, then the sky, then the ocean, then carbon dioxide and next up will be ground heat. There was a house last year that I think people were complaining about on Reddit, giant house out I’m the woods, all glass walls and heat pumps, labeled as green. It’s not a green building if you are 2x as efficient as fossil fuels but your house needs four times the BTUs of a reasonable design and 6 times a green one. Twice as efficient and half the heat loss is green. Blowing the surplus is not.
