I think this could be Resolved by scale, but that’s precisely what the west is really bad at
If we standardised ground source heat pumps as a must have all multi dwelling developments like apartment blocks and rows of terraced houses who could share one well et cetera, It would not be a noticeable cost at all
Maybe, where are live there isn't much ground water and so no well can deliver enough water to be useful for a large building HVAC needs. There are a lot of ground source heat pumps around me, but they are all the coil in the ground style which doesn't scale the same way and so will be a lot more expensive to install.
