Family house with 11 kW heat pump system

The heat demand of this family house is 11 kW, so a Junkers heat pump was installed with 10,7+9 kW nominal performance.

 

This heat pump supplies the domestic hot water demand, too and it has a weather-dependent regulator.
There are 2 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. This system utilized ~ 8,8 kW geothermal heat.
The free-cooling is done by heat exchanger on the primary side. The heat pump makes domestic hot water in a 165-liter tank.
According to the plan this heat pump system was installed by the HGD Ltd.

The owner gained financial support for the heat pump system installation in 2008
