Martin Jakob opened the 9th Symposium on Solar Energy and Heat Pumps – Thermal grids.

Thermal grids were in the focus of the Symposium held in Rapperswil. In his opening speech, Martin Jakob put them into context (“The big picture - The role of thermal networks today and in the future”). In addition to the talks, there was also a small accompanying exhibition and a large collector on the roof of the SPF could be visited.
