The heat exchangers may be installed using a penetrator that is driven into ground by a driving assembly. The driving assembly may drive the penetrator via a central drill string or drill rod and/or by overlapping driving members of alternating orientation. Tubes of the heat exchangers may be configured in a helical configuration and/or a straight configuration and/or be configured with an extended tube-to-tube spacing. Such extended tube spacing reduces tube-to-tube thermal conduction and increases tube-to-ground thermal conduction and thereby increases efficiency, effectivity, etc. of the geothermal heat exchanger. Sheathing may be positioned around the tubes for protection during installation. The sheathing and/or the driving assembly may place grout and/or other material around and or adjacent the tubes. A housing may be positioned around a fluid return portion of the heat exchanger tubing, and fluid passages may deliver fluid into the ground to facilitate penetration and/or to backfill grout during withdrawal. A removable sheath may be positioned around the tubing and selectively retained and released to permit sheath retrieval while leaving the tubing installed.
