ᐅ Mechanical ventilation with heat recovery in the hallway as well? We don't have that – the air feels stuffy.

Good morning everyone,

Quick question,
We have a controlled mechanical ventilation system from Wolf Excellent.

I keep noticing that the two hallways feel stuffy in the mornings. We have been living in the new build for about 1 year.
There is neither supply air nor exhaust air installed in our two hallways. Is this a mistake?

We have supply air in the following rooms:
Living room
Office
Bedroom
Child’s room
Guest room

Exhaust air:
Bathroom 1
Bathroom 2
Utility room
Dressing room
Kitchen

What do you think about this?
At the moment, I go there every morning and ventilate the hallways properly to get some air exchange.

Regards and thanks
Y

The only time it runs at reduced capacity is from 11 PM to 2 AM. Otherwise, it hums steadily.

We also have a Wolf unit, though I’m not sure which model.
In our case, it switches on for about an hour at 7 AM, 11 AM, 5 PM, and also for an hour at night. (No guarantees, something like that). It may run at other times as well, but you can’t hear it then.

But aren’t these systems supposed to run continuously to ensure that moisture is removed and fresh air is brought in? Otherwise, there is a risk of mold since the windows remain closed.

No, the systems can also be operated with sensor control, which may even switch everything off completely. It depends on the specific configuration.

But just because you keep the windows closed and don’t ventilate for a couple of hours, you don’t immediately get mold....

Yes, I understand, I’m just repeating what our heating engineer said.

Our system operates according to demand: after sleeping, after cooking, and so on.
