When you consider Ground Source & Geothermal Heat Pumps, you think about substantial ground temperatures which can produce very economical performance.

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

Horizontal Collector
Pipes within the floor at circa 1200 to 1500mm deep operate horizontally, with virtually all the thermal collection being website solar/surface heat derived as a result of shallow collector depth (valuable ground temperature begins at 15m depth).

Open Loop Borehole
Good levels of Heat Pump performance are achieved as a result of trusted temperatures that can be delivered from aquifer methods.
Here, a flow borehole plus a separate return borehole circulate ground/aquifer water to the Heat Pump.

All three systems present application advantages to suitable projects and may be configured as primary geothermal heat pumps ground source collector-driven heat pump systems, or air/ground dual-source systems to lower civil costs where necessary.
