Retrofitting external air supply for chimney

Since it probably depends on the chimney sweep, I would like to describe my demands from him. I have no residential ventilation, a wood stove with fresh air intake from outside but without certification, an oil-fired tiled stove, and an exhaust hood. The only demand was a double extraction flap, where an additional flap would open when the exhaust hood was in operation. Whether that worked was never checked. With the new kitchen, it could have remained that way up to a certain power of the exhaust hood. Therefore, ask the black man beforehand, preferably buy the wood stove from his supplier as well.

In living spaces, air is blown in, and air is extracted from the kitchen and bathroom, so why is a residential ventilation system a disadvantage? I don't understand that. Or maybe my physical thinking is not enough :-D

Argument of the chimney sweep: improper operation of the ventilation system possible, malfunction possible (supply air not working), filter clogged (too little supply air), etc.
Just discussed this morning. The DiBT certification of the wood stove doesn't matter to him (here at my place). I can just as well use a cheaper and non-certified combustion unit.

crazy how different it is. I'll share some info on what came out.

Answer from the chimney sweep: Please only buy certified stoves in the store! Requirement: Compliance with BImSchV Stage I and II or Din plus standard!

LOL. Are there decent stoves that do not meet this requirement? Even the cheapest products from Poland or similar (Kratki, Prity, etc.) comply with this standard by 98%. DIBt certification? What does he say about that?

It is very simple: Take a local stove builder, he knows the chimney sweep, knows what he demands, and you will get a beautiful wood stove just as you wish without stress. Requirement or not - in a house with air-extracting devices I would not want to do without a pressure monitor.
