Wouldn't it be cheaper/easier to dig a well, fill it with tubing, and pouring concrete all over? The concrete being the constant-ish temperature heat reservoir

  Would concrete have sufficient thermal conductivity compared to damp soil?

  My parents built a new home a couple years ago. The property had a well despite being on city water. They have other homes with ground source heat pumps. When asking the geothermal contractor if they could use the same well borehole, the contractor said why don’t we just circulate the water and not bother the existing well. So that’s what they do - their geothermal system uses the well water, circulates it through the condenser, then sends the water back down into the ground.

    This is fascinating! Is it possible to do this while utilizing the well for drinking water? I would assume so - it would just go through the condenser to exchange heat before being used elsewhere, and less would be pumped back down to the well?
