When you think about Ground Source & Geothermal Heat Pumps, you think about significant ground temperatures that can produce extremely efficient performance.
Closed Loop Borehole
Flow/return pipes working down/up inside a single borehole to depths of 150m + (a number of boreholes inside a system array).
Horizontal Collector
Pipes within the floor at circa 1200 to 1500mm deep run horizontally, with the majority of the thermal collection being solar/surface heat derived due to the shallow collector depth (beneficial ground temperature starts off at 15m depth).
Open Loop Borehole
Good levels of Heat Pump efficiency are attained due to the trustworthy temperatures which can be delivered from aquifer systems.
Here, a flow borehole as well get more info as a separate return borehole flow into ground/aquifer water to the Heat Pump.
All three systems present application advantages to suitable projects and might be configured as primary ground source collector-driven heat pump systems, or air/ground dual-source systems here to reduce civil charges wherever expected.
