> more than twice the initial cost

Here in Norway you can get a decent air-to-air minisplit installed for $2k. I've not heard of anyone who paid less than 10x that for an air-to-ground or water-to-ground system, drilling 500-1000 feet is expensive.

Sorry, I actually meant air-water vs. water-water for my comment, makes less sense this way...
