When you think about Ground Source & Geothermal Heat Pumps, you think about high ground temperatures that will provide very efficient performance.
Closed Loop Borehole
Flow/return pipes functioning down/up in a single borehole to depths of 150m + (numerous boreholes within a system array).
Horizontal Collector
Pipes beneath the floor at circa 1200 to 1500mm deep run horizontally, with the vast majority of the thermal collection being solar/surface heat derived as a result of shallow collector depth (useful ground temperature starts at 15m depth).
Open Loop Borehole
Good levels of Heat Pump performance are accomplished due to the trusted temperatures which 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 three methods provide application benefits to appropriate projects and might be configured as primary ground source collector-driven heat pump systems, or air/ground dual-source systems to cut get more info back civil prices wherever required.
