Chimney pipe through the house wall, need information

Good morning everyone,

we want to install a stainless steel chimney pipe on the outside ourselves. For this, we need to make a core drilling into the house. Can someone tell me at what height it should approximately be installed and how far away the power cables and empty conduits must be? What regulations are there for ventilation? We have a Kfw70 house without ventilation.

We haven't chosen a chimney yet, but we want a (masonry?) studio chimney with glass on three sides and a ledge for sitting.

Regards
Tobi

It's best to ask your responsible district chimney sweep master, who will also have to carry out the acceptance later, and if he is on board from the very beginning, nothing can go wrong. He can also help you with ventilation.

OK, spoke with him and clarified a few things. We have a kitchen island in the kitchen, where cooking is also done. Above it, we want to install a flat extractor hood in the suspended ceiling with an exhaust motor on the outside of the house wall. However, he now says that we have to connect it with a window contact to prevent air from being sucked out of the chimney. That is clear and logical so far. But he also said that recirculation hoods with charcoal filters are almost just as good and much more energy-efficient, as the external motors suck a lot of air out of the house. What do you think? I actually didn’t want recirculation...

Hello,

I can only agree with your district chimney sweep master.

In terms of energy efficiency, exhaust hoods (in winter) are not very good.

Take a look at recirculation hoods from "Berbel" on Aunt Google. They are not exactly cheap, but definitely as good as an exhaust hood and have (due to their design) quite low follow-up costs.

Regards,

Dirk
