For our new building with controlled residential ventilation, he says: I am only interested in the output of the stove in relation to the cross-section of the flue pipe in the chimney draft. The stove fitter must certify the correct construction of the stove, the ventilation installer that the system extracts as much air as it supplies, then they neither need a pressure monitor, nor a room-air-independent stove, nor a Dibt approval.
What the district chimney sweep wants, no one will ever sign, and the sweep is a pain in the ass that first lets you believe otherwise. My opinion on the whole thing is well known here. However, during construction, it is particularly sensible to talk to the district sweep and do things the way he wants. Or just go for a pressure monitor right away, because that is the only method the sweep can never object to (it is theoretically the best method).
No one will issue the aforementioned signatures to you permanently. The ventilation installer will definitely not sign off on this story. As always, no one wants to be responsible for anything. Of course, you can also take the ventilation system out of operation for the stove inspection ^^ in the end, it's a lot of fuss about nothing. If the weather is just unfavorable, even a pressure monitor will not help at all. The whole thing basically exists only to shut off the ventilation system if all supply air points in the house are simultaneously closed off and thus no new air is introduced into the house while air is still being extracted. Of course, this creates a huge underpressure.
