Hello everyone,
Since I now have to decide which wall or roof penetrations we need to use for the fresh air intake and exhaust air, I am looking into the various options available on the market.
On the north side, we have the possibility to take in fresh air through the gable. The north gable faces the street, so the solution should also look decent.
The idea is to route the exhaust air through the roof, but the south gable can also be used for exhaust air. The south gable faces the garden.
We are building a house on a slope, which means that from the street side you see one full story and the pitched roof with the attic and loft. The heat recovery ventilation unit will be installed in the loft.
So far, I haven’t found a fresh air intake and exhaust air solution that really convinces me.
What have you installed, and what makes sense?
We have a planner for the heat recovery ventilation system, but I want to take a broader look at what is available.
Regards,
Micha

You simply need two of thoseThat is incorrect; only one is needed. The Vallox weather protection grille is designed for both supply and exhaust air, so you could install it on the south side of your building and wouldn’t need a grille on the north side at all.
It has worked perfectly for us so far.

Sebastian792 Jun 2016 07:14Yes, I’m familiar with these issues, but I simply don’t trust such solutions—especially when there is poor air quality inside the house coming from certain corners...
Everyone talks about ventilation short circuits, but is it supposed to work there?

Sebastian792 Jun 2016 07:32That also doesn’t make sense from a ventilation perspective, because these are just weak airflows that cannot effectively circulate through the room…
Especially when you have a system for the first time, you might think everything is great – it’s definitely better than having nothing. In our rental apartment, there were also things like supply air above the door, incorrect disc valves, and so on.
