IMHO the costs of a controlled residential ventilation system are largely dominated by the installation and the ductwork. With only a small additional cost compared to the bare installation, you can then complete the controlled residential ventilation system... ...
Hello,
thanks for your tip.
So the system is supposed to be installed entirely by myself.
Well, the ventilation ducts with ceiling outlets will cost me about €1300.
The complete ventilation system then about €6000. I’m calling a dealer today.
As already suggested by , I have adjusted the drawing and marked the duct routing as I would install it. Cleared with a structural engineer, running ducts perpendicular under load-bearing walls is okay; he is now reviewing these drawings.
Now, the longest ventilation duct determines the highest pressure loss. Should I make a loop on the shorter ducts? Is that sensible??
Best regards
