Groundwater
If groundwater is available at a reasonable depth and quantity, as well as at an appropriate temperature, the highest annual performance factors can be achieved. A constant temperature of 8-12°C guarantees optimal heating operation. Two wells are required for this: a supply well and a drainage well. The drainage well should be located at least 15 meters away from the supply well in the direction of the groundwater flow. The required amount of groundwater is approximately 250 liters per hour for 1 kW of heating power. The yield must be demonstrated through a continuous pumping test. Certain limits for the water's constituents must not be exceeded or fallen short of, so a water analysis must be conducted. A water law permit is required.
Passive cooling: A heat exchanger is used to dissipate room heat. Additionally, the low temperatures in the groundwater are utilized for the cooling effect. In passive cooling, the heat pump itself is not in operation. Only the control system and the circulation pump are running. The cooling effect is less than that of active cooling with a heat pump.
