bortelHello 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

Hello,
If the unit is installed in the attic, the ground heat exchanger option is probably not feasible...
There are these roof vents that basically replace a roof tile. They look somewhat similar to a gas boiler chimney.
I wouldn’t take the outside air from the street side if the street has more than very light traffic. Just one polluting car is enough to spread the smell throughout the entire house.
If you’re building with a fireplace, it’s important to position the outside air intake as far away from the chimney as possible.
Best regards,
Andreas

So, we don’t have a chimney; the flue for the gas condensing boiler is located somewhere else. The street is only used by residents and occasional visitors, so traffic is absolutely negligible, in my opinion. There are only 17 houses in the entire area, and our building plot is situated in the middle of the development.
