→Geothermal Cooling
*The pump used to circulate the heat transfer fluid through the ground loop may be powered by an electrical connection or solar panels. Larger systems may need designated electrical connections.

*Initial investigations suggest that systems can be sized based on the average pond outflow rate over a given year to achieve defined temperature thresholds most of the time.

Geothermal Cooling works best with subsurface draw outlets (1.2 m or deeper) that provide cooling of the higher flows and would be less expensive than installing additional boreholes (at least in new builds). When sized appropriately, geothermal systems can shave a few degrees off of the average pond outflow temperature.<br>

See above an example of a geothermal system configuration showing the surface heat exchanger (SHX) in the vault and the borehole ground heat exchanger (GHX). An inexpensive pump circulates heat transfer fluid through the closed loop continuously.<br>
