If I ever had a GSHP system installed, there would be a "performance" clause in the contract. If my inlet water temp EVER fell below 40F, the installer would have to repair/replace/agument the ground loop. I would try to hold 50% of his installation fee in escrow for at least 1 year.
If you are going to pay the premium of having a GSHP,
you want one that is designed and installed for optimal performance !
