Whenever you consider Ground Source & Geothermal Heat Pumps, you think about substantial ground temperatures which can produce incredibly successful performance.
Closed Loop Borehole
Flow/return pipes operating down/up inside a single borehole to depths of 150m + (multiple boreholes inside a system array).
Horizontal Collector
Pipes beneath the ground at circa 1200 to 1500mm deep run horizontally, with nearly all the thermal collection being solar/surface heat derived as a result of check here shallow collector depth (useful ground temperature starts at 15m depth).
Open Loop Borehole
Good levels of Heat Pump website performance are attained because of the reliable temperatures which can be delivered from aquifer methods.
Here, a flow borehole and 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 charges where expected.
