ᐅ Installation of a Fireplace on an Exterior Wall with 50 cm Brick Construction

Hello everyone,

We are currently finalizing the very last details in our construction plan and are facing a challenge regarding the planned stove (or tiled stove / masonry heater). We hope you can provide some input.

According to the plan, the stove is to be installed directly adjacent to an exterior wall. Our initial idea was to make the stove accessible from the outside (through the 50 cm (20 inch) thick exterior wall). However, the builder is far from enthusiastic about this idea (keyword: thermal bridge, which may compromise long-term airtightness).

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

Thanks and best regards from Fuchsbauer.

What benefits do you expect from this solution? Less dirt? The chimney sweeper can come when no one is home (holiday home)?

We don’t have a cleaning door in the exterior wall – with the thickness of today’s walls, I would consider that a burden for the chimney sweep. The wood stoves the guys use connect to an interior, clad stainless steel chimney, and the masonry stove leads to an exterior stainless steel chimney.

I’m not happy with the whole detail: in all the plans in this thread https://www.hausbau-forum.de/threads/Planung-efh-in-Hanglage-Grundstück-optimal-ausnutzen.31172/, the chimney passes through the exterior wall—and an access hatch for cleaning would also penetrate the external thermal insulation composite system (ETICS). Who comes up with such nonsense, and what advantage is this supposed to have?
