Ground-Source(Geothermal)

What is Geothermal? Ground Source (Geothermal, Ground Loop Heat Pump or GeoExchange) - Two types... –Ground Water - open loop/well water Direct water use –Ground Coupled - closed loop Vertical earth loop Horizontal earth loop Surface water

Open Loop Systems

Vertical Loop System

Surface Water (Lake/Pond) Loop System

Horizontal Loop System (Slinky shown)

Hybrid Systems Ground Loop/Tower Ground Loop/Aquifer –Auxiliary Geothermal Heat Sink Benefits: –Off Peak Operation –Lower First Cost
