Ground source heat pumps install cost is very high when used in cold areas because of the frost depth caused excavation costs; significantly higher than the cost of the heat pump unit and parts themselves. It can be good if that disproportional initial cost is paid. But it's not the same class of purchase. This cost is reflected in the lack of demand and so lack of (solvent) installers.
If the big initial cost is rolled into home construction it would be less daunting and more normal. So I expect newer homes to adopt heat pumps in cold areas but with little adoption in existing homes.
- jcgrillo 2y agoI read somewhere that you can just drill a well and install a big coil?
- superkuh 2y agoNews to me. But probably similarly expensive once the environmental regulations for wells, etc, and it's excavation are considered. And even fewer installers who are qualified to do it.
- wood_spirit 2y agoYou are making this up as you go :) Yes they are often installed in bores into bedrock. All those pesky Scandinavians must be doing it because it makes economic sense. Step back and think that if you don’t know the details then all the excuses you can imagine are probably misleading or wrong.

Here is what you missed, >If the big initial cost is rolled into home construction it would be less daunting and more normal.

- wood_spirit 2y agoIn Scandinavia heat pumps are often replacing wood burners in existing houses. Source: I live there
