Abstract

A casing support of a geothermal borehole heat exchanger having an outer casing is provided. The casing support comprises a base support element 30 incorporating an aperture 36 through it, the base support element being arranged to be supported by a ground surface around a borehole. An annular orientation guide element 58 is provided at an upper surface of the base support element and has a central conduit (60, fig.7) communicating with the aperture. The orientation guide element has an upper surface 59 at a selected angle relative to a lower support surface 57 of the base support element. A casing support ring 54 is fitted around an outer casing 46 of a geothermal borehole heat exchanger, the casing support ring being coupled to the orientation guide element to support the casing in the borehole, where the outer casing extends through the ring, the conduit and the aperture. An associated method includes the step of drilling a borehole through the central conduit and the aperture at an orientation preset by the orientation guide element.
