Possible defects in installed controlled residential ventilation pipes - concreting will be done today

But your research does not agree with mine. What advantage is there in laying the pipes in the concrete, especially since all other lines are also laid on the concrete?

So, my research showed: + more cost-effective installation, since trimming insulation around the [Kontrollierte-Wohnraumlüftung] ducts is eliminated + round pipes are more common, produced in larger quantities, and therefore cheaper than oval pipes + less height in the floor construction, which is already significant due to underfloor heating, insulation, etc. + easier installation of the other elements on the ceiling, since nothing is allowed to intersect

What is your view on things?

Can only agree with the statements of sirhc.

Hello Sebastian,

did you receive my message from yesterday? It was supposed to be a personal message, but it probably ended up on the "wall" or something, and then I couldn't see it myself anymore.

Can you tell me the year and issue number of the CT edition on the topic KNX? I read a 15-month-old post from you there yesterday. :) I would also be interested in what you ultimately implemented, since we're already off-topic...

Thanks and best regards!

Oh, no - just saw it now.

The issue is already in the trash or in the moving container :D

There was hardly anything in it anyway - so it's not really anything worth knowing for someone who wants to implement KNX.

I don't have KNX because I never saw and still don't see any personal benefit for me. I implemented everything I wanted conventionally - some things a bit of tinkering, but it worked.

Thank you - and what a pity. I am also currently abandoning the topic BUS, as the 3 offers for conventional electrical installation that I have range between EUR 18,000 and EUR 22,000, which is already significantly above budget. :(
