When you give thought to Ground Source & Geothermal Heat Pumps, you think about high ground temperatures that will provide very efficient performance.
Closed Loop Borehole
Flow/return pipes running down/up inside of a single borehole to depths of 150m + (several 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 (valuable ground temperature begins at 15m depth).
Open Loop Borehole
Good levels of Heat Pump efficiency are reached as website a result of dependable temperatures that can be delivered from aquifer units.
Here, a flow borehole as well as a separate return borehole circulate ground/aquifer water to the Heat Pump.
All 3 methods offer application advantages to suitable projects and can be configured as primary ground source collector-driven heat pump systems, or air/ground dual-source systems to lower civil expenditures where expected.
