Decentralized ventilation units for larger rooms (old buildings)

Now a few filler words...

I don't understand that :rolleyes:
Is it possible to install such a device yourself if you are able to install a decentralized device?

Can you install such a device yourself if you are able to install a decentralized device?

Sure, you just have to have the volume flows calculated. Various manufacturers also design the system for you free of charge with an indication of the necessary parts.

You can't just respond here with "yes" or similar. A minimum number of words and characters is required.

very interesting.
Thanks!
Would you prefer a particular manufacturer for that?

One more question: Do you think about 20 meters of pipe length from the main unit to the room is a problem? I have now called an installer and he will take a look at the matter at the end of the month. Maybe I can save quite a bit by doing some of the work myself. So that I make wall openings and lay the pipes...

Would you prefer a specific manufacturer there?

No.

No. That should not be a problem either (select suitable devices and consider it in the calculation). Why not supply all rooms directly?

I just want to replace about 60% of the windows next year. In the other rooms with the (for now) old windows, it is not necessary at the moment. It is important that it can be easily expanded.
