Reine Energie Reinertrag

Family house with 17 kW heat pump system

The heat and cool demand of this family house are 17 and 9 kW, so a Buderus heat pump was installed with 16,8+9 kW nominal performance.


This heat pump supplies the domestic hot water demand, too and it has a weather-dependent regulator.
There are 3 pieces BHEs with 100 m depth on the primary side of this system. The pipes are single BHE with 40 mm diameter and the primary side is filled with ethylene glycol and water. The grouting material is bentonite-cement.
The free-cooling is done by heat exchanger on the primary side. The heat pump makes domestic hot water in a 433-liter combined tank.
According to the plan this heat pump system was installed by the HGD Ltd.
This implementation was state-supported in the frame of NEP-2009
