Always drill straight down to the water table at $12-$15 per foot.. Insure that you couple into the water tablemaking your GSHP the most efficient. Slinky tubes only 10 foot down are to much affected by the ambient outside air temperature making for less efficiency. 150ft of vertical loop per ton of cooling on a 15 ft square grid is good rule of thumb depending on soil conditions. The more vertical loop the higher the efficiency.. Heavily Insulate the top 15 foot of the vertical loop and its entry into the inside GSHP equipment. Your ground loop using modern pex tubing will outlive your homes 50 year life so yearly amortization is very low and significantly less than than your natural gas or electricity bill you would otherwise pay.
