Ground Loop 1) in a geothermal heat pump, system is a long series of pipes buried in the ground at the depth where temperatures remain consistent year-round: Vertical Ground Loop is installed in holes drilled deep into the ground with a closed-loop geothermal heat pump (Refer to the Closed Loop Geothermal Heat Pump System); Horizontal Ground Loop is installed over a wide area of ground and buried at the optimum level (Refer to the Open Loop Geothermal Heat Pump System); 2) in an electrical system, a ground loop or earth loop is two points of a circuit that is in a signal circuit referenced to ground, if enough current is flowing in the ground to cause two points to be at different potentials.
