Whenever you think of Ground Source & Geothermal Heat Pumps, you think about significant ground temperatures which can produce extremely effective performance.
Closed Loop Borehole
Flow/return pipes operating down/up within a single borehole to depths of 150m + (a number of boreholes inside a system array).
Horizontal Collector
Pipes under the ground at circa 1200 to 1500mm deep operate horizontally, with the vast majority of the thermal collection being solar/surface heat derived mainly because of the shallow collector depth (beneficial ground temperature starts at 15m depth).
Open Loop here Borehole
Good levels of Heat Pump efficiency are attained because of the reliable temperatures which can 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 advantages to suitable projects and will be configured as primary ground source collector-driven heat pump systems, or air/ground dual-source systems to lessen civil expenses wherever necessary.
