Which pressure switch do you recommend? Any experiences? We want to operate a fireplace (room air-independent) that requires a pressure switch. We will have decentralized ventilation from Inwert.
The chimney sweep said the fireplace must be tested at 4 Pa (0.016 inch water column) and the pressure switch must activate at 4 Pa (0.016 inch water column).
Wouldn’t the ventilation system keep shutting off constantly then?

Hi,
You are certainly not naive.
However, what Nordanny said is correct.
Although we had laid the necessary wiring, we were able to provide the required documentation (including a *current and valid* DIBt certificate for the chimney and ventilation system, which also covers the functionality of the fireplace operation and fireplace booster), and after a longer discussion, it proceeded without the UDW.
The latter is certainly more the exception than the rule.
It is a discretionary area for the building inspector (BSFW), and the decision for or against the UDW was made by us only at the very end after reviewing all on-site conditions… before that, the topic was open and rather in favor of the UDW.
Best regards
Thorsten

I was happy to pay the 380 euros for the protector, for the sake of my family.
It also recently triggered when the oil heating system was burning inefficiently and caused negative pressure.

Absolutely correct. Seals on wood-burning stoves are wear parts.
My chimney specialist comes by once a year to check on them.
(It was the same with my first wood stove from 2000 to 2006).
At the slightest sign of wear, I always have the seals replaced.
Best regards,

Our chimney specialist recommended installing a pressure monitor because then we wouldn’t need a DiBt-certified stove, which means we would have a wider range of models to choose from. Certified stoves are usually more expensive, so the overall costs end up about the same when you consider the pressure monitor plus a non-certified stove.
He also mentioned that with a room size of approximately 70 square meters (750 square feet) for the open kitchen and living-dining area, we might not necessarily need an air-independent stove. Since we will likely install an exhaust-controlled mechanical ventilation system with decentralized wall vents anyway, fresh air supply is ensured...
Tomorrow I’m going to a specialized fireplace store again. Let’s see what advice they give us.

@ fenix.... how is your pressure switch going to be installed? Are all decentralized fans wired to the switch? Do you have any information about that yet? No. These are only decentralized passive wall vents without fans. My knowledge on the matter is still quite limited. I will inquire with the chimney specialist tomorrow.
