Controlled residential ventilation / DIBT stove / pressure monitor

Yes, I have news - the fireplace is about to be installed, the BezirksSchorni "doesn't need" a pressure monitor because the stove is certified. The power cable has already been laid and is now dangling around the chimney.

Gives hope

I also planned a conduit from the stove to the controlled residential ventilation, better safe than sorry.

For us, it will be an external chimney, but that doesn’t matter.

So either install a pressure switch or an "intrinsically safe controlled residential ventilation system."
Since the controlled residential ventilation system installed in our house is intrinsically safe, the pressure switch can be omitted in our case.

Hello Michael,
may I ask which controlled residential ventilation system you had installed in your house? Are you satisfied with your controlled residential ventilation system?

Hi.

We have installed a system from Pluggit.
I’d say it does what it’s supposed to do, fresh air.

Hello,
I am bringing up this topic again.
I have a single-family house built in ’55, made “airtight” in 2009 with new windows, vapor barriers, and insulation. To avoid mold formation, I installed a controlled residential ventilation system (Helios Controlled Residential Ventilation EC 450 Pro).

Now I have indulged in the luxury of a wood stove. After talks with several stove builders, it was clear that I need a certified RLU (room air-independent) stove. So I willingly spent 500 euros more and now have a hard-to-access ash pan – never mind.

The chimney sweep is now causing trouble who, despite the RLU, demands a pressure monitor. I do have letters from the Association of Chimney Sweeps and from the DIBt, stating that for certified RLU further safety measures would be excessive; nevertheless, the chimney sweep demands a certificate that the KLW cannot generate more than 8 Pa.
The system manufacturer and ventilation company cannot provide this confirmation. It’s clear that if the system runs at the highest level and then the supply air fan fails, 8 Pa will probably be reached.

Now I do not want to install a pressure monitor because: breaking walls for cables, about 1000 euros, ugly control panel in the living room, and why did I buy RLU at all.
Besides, the pressure monitor is not a 100% safety device either. What if I have a negative pressure below the triggering threshold (4 Pa) and the door is slightly open, e.g., by a piece of wood?

Isn’t it much more sensible to install a CO detector?
Those things sound an alarm only when there really is a problem, are battery-operated and easy to install anywhere, have a self-test, and cost only a fraction.

Unfortunately, only your responsible chimney sweep can answer this question for you. He and only he approves or rejects it. If he requires a pressure monitor, you will unfortunately have to bite the bullet.

We discussed the possible options with the chimney sweep before purchasing the stove and manage with an RLU stove and controlled residential ventilation without a pressure monitor.
