Whenever you think of Ground Source & Geothermal Heat Pumps, you think about significant ground temperatures that may provide very efficient performance.
Closed Loop Borehole
Flow/return pipes running down/up within a single borehole to depths of 150m + (multiple boreholes inside a system array).
Horizontal Collector
Pipes beneath the floor at circa 1200 to 1500mm deep run horizontally, with virtually all the thermal collection being solar/surface heat derived mainly because of the shallow collector depth (valuable ground temperature starts off at 15m depth).
Open Loop Borehole
Good levels of Heat Pump efficiency are accomplished due to the reliable temperatures which can be delivered from aquifer methods.
Here, a flow borehole along with a separate return borehole circulate ground/aquifer water to the Heat Pump.
All more info 3 methods provide application benefits to appropriate projects and might be configured as primary ground source collector-driven heat pump systems, or air/ground click here dual-source systems to scale back civil expenses where expected.
