WESPE Project
Berlin (GER), October 2026 - Heat pumps are an efficient and future-proof key technology for the energy transition in heating systems and for achieving Germany’s climate goals. In the WESPE project, Fraunhofer researchers and their partners are working to make heat pump installation faster, more productive and more efficient to support the transformation of the heating sector, despite a shortage of skilled workers. Innovative, standardized digital tools and practical installation solutions tested in real-world conditions are to significantly speed up future heat pump retrofits.
