There seems to to be no one interested in developing the geothermal potential possibilities of shallow 100'-500' wells. I think if a heat pump were used to extract heat from the 53 deg f wells the cost effectiveness of suppling 70 deg f water for subfloor radiant heat systems would be excellent.
Has anyone tried such a system?
Are there any books or papers on the subject anyone could refer me to please?
Thank you, Jim
