If executed correctly (follow the assembly instructions), nothing can get between the plate and the facade. The pipe extends up to the flap, i.e., beyond the base plate. The gap between the pipe and the base plate opening is then sealed with silicone. However, the exhaust air does not reach this sealing area at all due to the protruding pipe. Only condensation moisture may accumulate here.
And with the others, where the mechanics are in the wind tunnel, condensate can form just the same. A look at the assembly drawings shows quite a few corners and edges where the air must flow past. Likewise, the other wall boxes also protrude beyond the pipe on the sides and thus have a contact surface with the exterior wall, where condensate could form as well.
Furthermore, for the remaining boxes, an incoming pipe must be inserted. How is it ensured here that the transition from the pipe to the box is sealed and no condensate forms? With Weibel, the pipe can run all the way through to the outside.
But as I said, Weibel is a fixed factor.
I only wanted to point out the disadvantage of heat loss. And regarding this topic about air volume in relation to pipe size etc., you gave me a very good and plausible answer. Many thanks for that. But I’m not concerned about “a few cents,” though theoretically that might add up over the year if you were to calculate it. But exhaust air is also a fixed factor.
If the difference in exhaust air volume is only slight and the exhaust stage does not change as a result, then a smaller pipe seems more sensible to me because it tends to cause less heat loss.
Smaller pipe means 125 is sufficient according to the Miele table.
Then the only "question" is whether I have chosen the right size.
