You’re always ranting, but apart from speculations, there’s nothing to read – if you come to the district plumber with that, he’ll just smile at you tiredly and walk away. Whole forums? You tend to exaggerate...

By the way, carbon monoxide poisonings don’t happen exactly rarely and people really notice nothing...

You can keep playing the H-man, no one will care.

Just because you can’t imagine something doesn’t mean it’s always nonsense.

Manipulation? I just call it a failure of the fresh air fan, then you have your case...

But it’s all exaggerated and typically German anyway.

please show me a court ruling where a chimney sweep had to pay even 1 lousy euro to anyone for anything.

Due to current circumstances and data protection, unfortunately not possible Also: not everything ends up in court!

if you come to the district chimney sweep with that, he will smile at you tiredly and then leave.

After initial doubts about this guild, I have come to trust it.

These people are very responsible.

Their word simply counts. There is hardly any opposing it.

However, it is possible to argue with appropriate documents and expertise. For this, you really have to be perfectly prepared and know everything, be able to provide evidence. That is my experience. My last conversation in that regard lasted almost 3 hours.

My former "enemy" (the BSFM) almost became a friend; he has now also received a long-term assignment from me.

We are having the Leda LUC-2 installed. We were also very naive about the topic. We knew that the switch for the decentralized ventilation was a special request, and so the matter was settled for us, and we had a room-air-dependent stove. Bad luck, because that was not the case. Our electrician later connected the ventilation to the fuses and ran a cable from there to the LUC. Many phone calls took place beforehand with the chimney sweep. It is best to involve the chimney sweep from the beginning regarding the model as well.

Hi,

This has less to do with building law. There is the SchfHWG, from §8 on the tasks of the district chimney sweep are dealt with.

By the way, the BSFM performs sovereign tasks – he puts his head and his license, thus his existence, on the line if he is sloppy. Being sloppy obviously also includes letting something slide that he considers unsafe.

It is also not called arbitrariness, it is called discretion!

Happy Easter!

what you write is exactly the definition of _arbitrariness_. It is completely irrelevant whether something is "unsafe in his eyes." What should count solely is whether it is objectively unsafe. And that is indeed absolutely clear and definable. The physics of a chimney and the thermodynamic processes of combustion follow certain regularities, namely natural laws. And those are the same all over this planet, there simply is no room for discretion!

If a certain combination of chimney, stove, ventilation, and extractor hood is safe in Hamburg, then it is also safe in Munich, Hintertupfingen, and Timbuktu. It is more than just silly to leave it dependent on the goodwill of whoever happens to be responsible.

Aside from this silliness, such a non-objective decision-making procedure also opens the door wide to errors. The reverse case can easily occur, namely that the BSFM gives his approval for something where he should rather have said no.

I hardly believe anyone would willingly get into a car whose brakes were designed and tested according to "discretion"...

Please don't misunderstand, the usefulness of a pressure monitor is not in question here. I am simply once again amazed, for the umpteenth time, at how completely unregulated and essentially random many things in construction (and everything around it) are. In mechanical and plant engineering, I struggle with God knows how many regulations that prescribe every little detail of crap, and for that I can really only compare building law to the Wild West...

Slightly dismayed greetings,

Andreas

Of course he has to show you the basis if he wants something from you. Otherwise, you just refuse the changes and he has to report it. At the latest then, it will be clear whether his demands are lawful. And I consider it completely impossible that anyone in Germany has to be liable for anything. Please show me a court ruling where a chimney sweep had to pay even 1 lousy euro to anyone for anything. It's all huge scaremongering and nonsense, because he can talk his way out with the simplest tricks (he only checks the condition at exactly the time of the inspection, parameters can have changed already when he leaves...)
A chimney with DiBT approval is completely sufficient, as there is no technical condition where the ventilation system can build up really strong pressure, except through extreme! senseless manipulation of this system (you would have to airtight seal ALL supply air ducts in the house simultaneously—makes no sense and cannot happen technically on its own). And then you are actively involved and can prevent the damage. It’s not like you suddenly collapse.
Not without reason, there are entire forums against chimney sweeps, where the sweepers come with completely exaggerated demands and courts have to deal with this nonsense. Either there is a clear law and you are out of luck or there isn’t one, and the sweeper is just talking rubbish.

As I already said, for new builds better the pressure monitor instead of the DiBT approval. The sweeper then has all hands tied (simply because everything has been done) and theoretically you can use any chimney you want.

Sorry, but what you write is nonsense—at least regarding the area of negative pressure and ventilation systems or DiBT certification.
A certified chimney is not enough. This is also nowhere stated to show the “clueless” sweeper. Furthermore, there are enough ventilation systems that continue to extract air from the rooms if the supply air fails. Or what happens if the door to the combustion chamber is accidentally not closed properly? Then the certification is useless...
So please do not give advice that later has to be corrected at great expense.
