    You can dig straight down, and run the ground loop vertically, but it’s surprisingly expensive to dig the hole. Like 15-40k expensive.

      I gotta say I understand the cost. Dig a full size grave by hand some time. It’s freakin exhausting. And sure, an excavator can do it in minutes, but that means you’re paying for time on a very expensive machine.
