When you give thought to Ground Source & Geothermal Heat Pumps, you think about high ground temperatures which can deliver very efficient performance.
Closed Loop Borehole
Flow/return pipes operating down/up in a single borehole to depths of 150m + (multiple boreholes within a system array).
Horizontal Collector
Pipes within the floor at circa 1200 to 1500mm deep operate horizontally, with virtually all the thermal collection being solar/surface heat derived mainly because of the shallow collector depth (beneficial ground temperature starts at 15m depth).
Open Loop Borehole
Good levels of Heat Pump performance are attained because of the reliable temperatures which can here be delivered from aquifer methods.
Here, a flow borehole along with a separate return borehole flow into ground/aquifer water to the Heat Pump.
All 3 systems present application benefits to suitable projects and will be configured as primary ground source collector-driven heat pump systems, or air/ground dual-source systems to scale back civil expenses wherever needed.
