Floor construction in height with Vallox KWL pipe routing questionable

Yes, it still isn't the best solution. For flat ducts, everything is usually made flat; otherwise, they lose their purpose.

For example, like this:

or like this, where no distributor boxes are used at all:

The problem was your planner, who should have explained the space requirement to you—or even better: banished the boxes to the technical room. But that won’t work with the wiring routing for round pipes anymore, right?

How about coming up with flat ducts from the technical room and laying them under the screed? And: definitely do not use distributor boxes that are two units high, only single-row ones!

Alternatively, you can also play 3D Tetris—do you have half-height pre-walls in the bathroom, like at the toilet? Maybe you can also fit the boxes in if you extend the wall there all the way up.

Exactly, the planner was not really impressive. Two new holes had to be drilled in the ceiling because the outlets were not planned correctly. The distributors were already the flattest variant.

With us, two very thick sheet metal ducts run through a riser from the basement up to the attic, meaning that from the basement three floors would have to be supplied via the two main ducts by the flat ducts. These flat ducts, then branched off multiple times, should not be able to deliver the required capacity without a distributor.

ValloFlex VVK 12563/6 air distributor

already saved 2 cm installation height....

The currently installed distributor is 16 cm high and the 75 mm piping does not fit. It should not be sufficient according to the calculation.

Hi,

which unit is for which air in your first picture? Is only this one vent connected to the right unit (exhaust air?) or is something missing in the photo? Maybe these two round red ducts could be replaced by flat ducts and led directly into the utility room. That way you could save one unit.

So on the left is the supply air and on the right the exhaust air. However, the picture is from the bathroom on the upper floor, i.e. the utility room is two floors below. You can't see all the connections on the right box... there are also four.
