Installation of a chimney on an exterior wall with 50 cm bricks

Hello everyone,

we are currently going through the very last details in our polishing schedule and are still facing a challenge regarding the planned stove (or tiled stove/heating fireplace) and hope that you can provide some input here.

According to the plan, the fireplace is to be placed directly adjacent to an exterior wall. Our initial approach was to make the fireplace accessible from the outside (through the 50 cm thick exterior wall). However, the builder is anything but enthusiastic about this idea (keyword: thermal bridge, cannot guarantee airtightness in the long term).

Has anyone of you installed the cleaning door in the exterior wall? And if so, how did you do it?

Thanks and best regards from the Fuchsbau.

Our first approach would have been to make the chimney accessible from the outside (through the 50 cm thick exterior wall).

Why should it be like that? Which chimney sweep would be happy to clean the chimney through a 50 cm thick wall (if he can even reach it)? Will he even agree to do that? In my opinion, a stupid and nonsensical idea.

Yes, stupid idea, you can do that with an external stainless steel cable.

Your answer is unfortunately not helpful like this. Could you perhaps make suggestions on how you think the matter could be approached better?

Thank you.

Hello Lumpi_LE,

we are seriously looking for a sensible solution. So, if you have a tip, we would appreciate your opinion.

Thank you very much.

Yes, it is. Talk to your mechanic. He knows the possibilities or can tell you whether he even gives his approval. By the way, you shouldn't be surprised that there are no concrete or convenient answers to nonsensical questions. There is probably no one who has implemented something like that and could answer you.
