ᐅ Controlled ventilation system + fireplace + kitchen exhaust – does this work?

Hello!

After some back and forth, we decided on the option “ventilation system – room air-independent stove – recirculating hood” for our apartment, since actually all three things (i.e., ventilation system – room air-dependent stove – exhaust hood) exclude each other.

Additionally, a pressure monitor was installed, which will shut off the ventilation system in case of emergency (we were told at the time that this can only be omitted if a certain stove is installed, but we didn’t like that one).

We were strongly advised against using an exhaust hood in this setup.

I have contacted the chimney sweep to see what he thinks about this.

But I can easily do without the exhaust air, so I think it will probably come down to the same combination as you have.

I have an appointment at the kitchen studio next week and will get updated on recirculation options. They say there are now very good filters available that capture odors.

Vaillaint recoVair will be used, but there are definitely many different models..

No, there are currently only three different sizes, nothing more.

Otherwise, I guess the local chimney inspector will require a USA. This can then disable the controlled residential ventilation and the extractor hood if a negative pressure occurs when the fireplace is burning. This simply means that the hood might suddenly turn off, even if you are cooking at that moment.

It will be a Vaillant recoVair 260/4.

I’m waiting to see what the chimney inspector says, and then we’ll decide if everything can be done at the same time without a lot of extra effort.

We have to install a negative pressure monitor in our home, even though we have a room-air-independent stove (tested according to DiBt standards), which will shut off the mechanical ventilation system in case of emergency... Initially, we also did not opt for the negative pressure monitor and chose this stove in part because of that... However, since our ventilation contractor does not provide written confirmation that the maximum negative pressure of 8 pascals (0.03 inches water column) will not be exceeded, the monitor is required.

As mentioned above: Even if you present a test certificate, it is ultimately up to the chimney sweep’s discretion, and they usually prefer to play it safe.
