CAN A GROUND SOURCE HEAT PUMP PROVIDE SPACE HEATING AND HOT WATER

Energy storage ground source heat pump

Geothermal heat pumps, also known as ground-source heat pumps (GSHPs), earth energy systems, or ground-source systems, utilise a closed-loop system that combines a heat pump with a ground heat exchanger (GHE). In certain cases, an open-loop system can be employed, utilising ground water.
