Abstract: An installation tool for installation of earth loops includes a cylindrical body with slots in its outer surface, for receiving of tubes of the earth loops, and a central passage extending therethrough from a grout fitting to a central opening at a leading end face of the cylindrical body. An anchor fits over the end face and includes a face plate with tube apertures extending therethrough, a retainer ring which serves to hold the earth loops in place within the slots during insertion of the tool into the borehole, and a pair of flexible plates extending from opposing positions on the retainer ring, approximately in parallel with the longitudinal axis of the cylindrical body.
