ᐅ Decision: Single-Room Ventilation or Centralized Whole-Home Ventilation

What do you want to hear from us now?

Both solutions are practical and feasible...

Thank you for the response.

I would like to discuss the pros and cons of both options.

For example, hear about experiences forum members have had with either solution.
What to pay attention to.
Or hear from experts which solution they would prefer and why.

Hello,

This topic has been discussed very intensively in recent weeks – please take a look in the relevant forums or use the search function. I can well imagine that users are currently less inclined to revisit this subject again.

Kind regards

Usually, the conclusion is that there is nothing better than the solution the particular poster has chosen! ;-) Sometimes the debates get really heated ;-)
Honest statements like "I really messed up back then..." are as rare as finding a needle in a haystack and are far more valuable than the usual self-praise!

This usually requires a sufficient basic assessment and examination of the data related to the individual requirements. That means effort and ultimately costs, which of course no one wants to pay.

For every pot, an individually suitable lid can be found, but this requires a certain amount of effort = cost.
The variety of lids available is almost endless! ;-) It becomes difficult to find the right fit if you don’t actually know how big the pot is! ;-)

Best regards

Hi,

these two threads were suggested by Bauexperte:

https://www.hausbau-forum.de/Lüftungsanlagen-Wärmerückgewinnung/9077-ventilatoren-fuer-feuchtraeume-und-abluftdunstabzugshaube.html
https://www.hausbau-forum.de/Lüftungsanlagen-Wärmerückgewinnung/8498-kfw-70-36er-ytong-lüftungsanlage.html

They openly discussed the pros and cons of different ventilation system models (without focusing on any specific system). I found the discussion very insightful because it helped clear up some reservations and prejudices (including my own). However, this discussion mainly applies to new construction. I cannot say how the specifications would affect an existing building.

Otherwise, as €uro nicely put it: contributors often strongly support their preferred system model, especially if they have had positive experiences and are convinced by it.

Thank you for all the contributions!

I have already gathered extensive information and am still undecided between a central system for each apartment and individual units.

Opinions are of course just opinions, but they are valuable to avoid falling into a "trap."

In our area, more and more decentralized ventilation systems can be seen on the air inlets and outlets on the facades of new buildings.

One question about decentralized ventilation (see picture in the original post):

How would the ventilation for the bathroom (which has no toilet) and the separate toilet be implemented?
The kitchen and living room could be ventilated through one unit, as the door between these rooms is usually open.
A unit would also be necessary for the bedroom.

Please only posts that focus on technical details, no general comments like the one from e.g. 12/11/2013, 11:35.
