Most ground source heat pump systems comprise three indoor elements being the heat pump itself, a hot water tank and a buffer tank which improves the efficiency of the ground source heat pump by levelling out peak heat demands. The capacity of the two tanks will be dependent on the size of the property whilst most ground source heat pumps are comparable in size to a fridge freezer. Many ground source heat pump systems combine individual elements such as the heat pump/hot water tank or the hot water tank/buffer tank into a single unit thereby saving space.
Typically, a ground source heat pump will be located in a plant room, utility room or garage. If planning a new build property, it is always advisable to consider where to accommodate it and tanks at an early stage of the design which Fervo would be pleased to discuss this with you.
