    > 100 meter borehole into the ground
I have heard from a couple of different Swedes talking about when this was installed in their childhood/high school years. It must be reasonably common at this point in Sweden. Are there special machines that pull up to your home and bore a deep hole? That seems like very specialised work for the average contractor! Also, does the gov't offer subsidies from this (presumably) expensive home improvement?

It's a specialized job but it's not difficult finding a contractor for it. When my parents did it ~30 years ago I think it cost around $10k. https://www.thermia.se/bergvarme-jordvarme/bergvarme/install...

Standard well drilling rig. Most farms around the world have their own well, so it isn't uncommon. Self sufficiency magazines used to have ads for DIY drills.

Expect to pay $10-20k for the hole but it is common in large parts of the world.
