Hello,
we are planning a new building according to KfW 297, EH40 standards. Currently, we are looking for a suitable central ventilation system with heat recovery. Now the energy consultant mentioned that only units with DIBt approval are allowed? I am not sure about this—does anyone have experience with this? Thanks! Good luck

Are there any without DIBt approval? You can check the DIBt website. Just enter “dibt / controlled residential ventilation” into a search engine. That will lead you to the overview.

Thank you! Unfortunately, the search only shows non-preferred systems…

Due to installation under the ceiling, as well as reviews etc., the Viessmann Vitoair FS and Blauberg Komfort are favored.
