When you give thought to Ground Source & Geothermal Heat Pumps, you think about substantial ground temperatures that can provide extremely successful performance.

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

Horizontal Collector
Pipes within the ground at circa 1200 to 1500mm deep run horizontally, with the vast majority of the thermal collection being solar/surface heat derived mainly because of the here shallow collector depth (valuable ground temperature get more info starts off at 15m depth).

Open Loop Borehole
Good levels of Heat Pump performance are achieved due to the reliable temperatures that can be delivered from aquifer systems.
Here, a flow borehole and a separate return borehole flow into ground/aquifer water to the Heat Pump.

All 3 methods present application advantages to suitable projects and may be configured as primary ground source collector-driven heat pump systems, or air/ground dual-source website systems to scale back civil charges where required.
