Research project

Sentmatt - Heat generation with deep geothermal probe, efficient low-lift heat pump and optimised heat distribution

In this P&D-project a highly efficient heat supply for residential buildings in Obfelden was realized with new technologies. The combination of a low-lift heat pump with a deep membrane geothermal probe and a new type of control of the heating distribution system enables efficient heating in winter and cooling in summer with the lowest electrical energy consumption. The evaluation of several years shows how important monitoring and operation optimization are to realize efficient systems in the field. In addition to many valuable field experiences, the project has shown that a holistic concept can make a significant contribution to the stabilization of the Swiss energy supply.
