Does it have to be a Helios ventilation system? Or are you allowed to choose alternatives? Then I would, for example, look out for Zehner installers. Around Nuremberg, however, there seems to be only one installer who really knows a lot about heat pumps, BAFA funding, and proper heating load calculation.I slowly feel like I live in the Dummsdorf region when it comes to this topic.
