AC_Hacker I will approach this with some caution. The ground loop now is a mixture of propylene glycol and water protecting from freezing down to -15 Deg C. But if my loop approaches 2 Deg C I'm going to stop the system I don't what to freeze the ground around the loop tubes. I've heard some stories about making permafrost. And airconditioning in the summmer is not the cure.
