When you think about Ground Source & Geothermal Heat Pumps, you think about substantial ground temperatures which will deliver incredibly effective performance.
Closed Loop Borehole
Flow/return pipes running 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 majority of the thermal collection being solar/surface heat derived due to the shallow collector depth (valuable ground temperature begins at 15m depth).
Open Loop Borehole
Good levels of Heat Pump efficiency are achieved a result of the trustworthy temperatures that can be delivered from aquifer units.
Here, a flow borehole as well as more info a separate return borehole circulate ground/aquifer water to the Heat Pump.
All three methods offer application advantages to appropriate projects and can be configured as primary ground source collector-driven heat pump systems, or air/ground dual-source systems to lower civil expenses where necessary.
