I saw a geothermal set up where they buried 8 copper lines each 150 feet long horizontally at a depth of 6 ft. They ran to a central feed line to the house to heat. Seemed to work fairly well. I'd think a pump would be involved.
I saw another set up where 300 ft deep wells were drilled and that water was used to heat the floor via pex tubing.
I don't entirely understand the principles of geothermal other than the ground has a constant 54 degree temp. If the ground gets 54 degrees below the frostline why wouldn't a 25 ft well work? We have a ton of nurseries around here with equipment for tractors that drill to 25 ft that we could utilize.
Has anyone installed a DIY geothermal system?
