Question about everyday life with a controlled residential ventilation system

How does it actually work when integrating a heat pump that cools in summer? Is an evaporator then installed in the ventilation system to cool the house? With the FB water circuit it probably doesn't help much except cold feet.

We once inquired about this at Viebrockhaus, there it is done exactly like this via the underfloor heating. That's why it's also uninteresting for us; I don't need cold feet.

Apparently just as little as you - but sure, let's leave it at that.

Well, Pneumatics is not just a Greek word for me... apparently you are not quite clear on the difference between controlled and uncontrolled ventilation, but I am. Unlike you, I can also directly observe the pressure changes in my system as soon as a window or door opens. That's why I know what I'm talking about.

But as I said, if you're happy opening windows, then go ahead, but I wouldn't recommend it if you don’t know what’s going on behind the scenes. The next person will think it must be that way and if their system then doesn’t work as desired, they'll look for the fault with the manufacturer and not in their own user behavior.

You should really read carefully - I didn’t recommend anyone to open a window. Furthermore, I didn’t write that the system would still run correctly afterwards - I was solely referring to your (completely exaggerated) statement that this would increase the wear and tear of the system (to whatever extent - it sounded alarmingly high, at least).

So don’t put such nonsense in my mouth...

And if that were the case, what would be so bad about leaving a window open? It would then be a temporarily constant state - or are you also not allowed to go through a patio door anymore or even open the front door for a chat?

Well, I did read correctly... your initial post reads exactly like instructions for permanently leaving windows open despite controlled residential ventilation...

No, you interpreted that into it – and the discussion was about the wear and tear, which you simply ignored afterwards.

But for you, here it is again: I also find window ventilation stupid, but I can understand people who miss the feeling of fresh air with the [Kontrollierte-Wohnraumlüftung]. In my opinion, it is also stupid to talk here about increased wear and tear of the system.

But what is unfortunately the truth, even if you do not want to believe it...
