Abstract

A casing support of a geotherrnal borehole heat exchanger having an outer casing, the casing support comprising a base support element incorporating an aperture therethrough, the base support element being arranged to be supported by a ground surface around a borehole, an annular orientation guide element at an upper surface of the base support element and having a central conduit communicating with the aperture, the orientation guide element having an upper surface at a selected angle relative to a lower support surface of the base support element, and a casing support ring fitted around an outer casing of a geotherrnal borehole heat exchanger, the casing support ring being coupled to the orientation guide element to support the casing in the borehole, the outer casing extending through the ring, the conduit and the aperture.
