Installing controlled residential ventilation in the basement - outdoor air / exhaust air, tips?

2020-05-02 18:52:36

Hi ,

I am facing the same question. I want to install a Zehnder Q350. Initially, two ducts were recommended to me. However, there are various reports on the internet about mold, especially on the exhaust duct. Therefore, I will probably use the ComfoPipe System 2 stainless steel pipes for supply and exhaust air below ground level. It doesn’t look particularly nice, but I don’t want mold on the house wall.

PS: The mold sometimes only appears after a few years.

: How did you solve it?

Regards, Joachim

We have the system in operation. Great device. Supply and exhaust air through stainless steel towers. Placed so that they don’t bother anyone. Exhaust noise on level 1 is almost inaudible, on level 2 quite noticeable, and level 3 is extreme, especially at night.

But usually, the system only runs on level 1. Level 2 is only sometimes during the day. So no problem at all.

Thank you for your feedback. Are the noises heard inside at the outlets or do you mean outside by the towers?

How was the system installed? Flat duct or round duct? In the concrete ceiling or in the floor structure? Are the outlets in the ceiling, wall, or floor?

I meant noises outside at the towers. Inside you can hardly hear anything, except for the fan somewhat in the equipment room. The system was installed as a round duct in the concrete ceiling. Outlets are installed in the ceiling.

My exhaust air goes into a pseudolight shaft (so just a shaft without windows) and I've never heard anything... It probably also depends on the system.
