Whenever you think about Ground Source & Geothermal Heat Pumps, you think about substantial ground temperatures that can provide extremely effective performance.

Closed Loop Borehole
Flow/return pipes working down/up in a single borehole to depths of 150m + (several boreholes inside a system array).

Horizontal Collector
Pipes under the floor at circa 1200 to 1500mm deep operate horizontally, with the majority of the thermal collection being solar/surface heat derived because of the shallow collector depth (beneficial ground temperature begins at 15m depth).

Open Loop Borehole
Good levels of Heat Pump efficiency are accomplished due to the reliable more info temperatures that can be delivered from aquifer units.
Here, a flow borehole plus a separate return borehole flow into ground/aquifer geothermal heat pumps water to the Heat Pump.

All 3 systems offer application benefits to appropriate projects and will be configured as primary ground source collector-driven heat pump systems, or air/ground dual-source systems to lower civil expenditures wherever needed.
