Cost of a stainless steel chimney

About exactly 2 years ago (energy crisis!) about 10% cheaper, however DN150 (is that enough?) at 9 m. Also wall and roof penetration. Measure has been coordinated with chimney sweep?

The stainless steel chimney for the masonry stove cost €3568.

Text from invoice 2019: The chimney system (stainless steel double-wall lightweight chimney) was installed and mounted from the ground floor up to approximately 1.80 m above the roof surface. This is a double-walled stainless steel chimney with F 90 fire protection. The chimney system was connected to the masonry stove on the ground floor (terrace) via a core bore through the house wall and a T-piece. A Coolblock was installed in the house wall for fire protection reasons. Stainless steel pipes in double wall were installed in the visible area up to under the ceiling. The chimney was integrated into the roof surface, sealed, and extended approximately 5 m above the roof surface. A chimney outlet piece with a rain cap serves as the chimney cover. Two inspection openings were installed in the chimney system for the chimney sweep.

I paid 2500 for 10 m only material costs back then.

Back then. We also about the same.

10m, 150mm,

However, no asparagus, that must have been at least 20cm wide. Considering that you don't get brackets or extensions for free either, plus the installation, then it fits.

180mm diameter is actually not standard and expensive. Roof penetration is expensive. If it is a timber frame house, the area around the pipe must be bricked up, which is also expensive. You have an offer with material prices and can compare them with the internet prices. A craftsman should only be 20-30% more expensive.

The pipe diameter is calculated based on the connected stoves. 180mm is a usual diameter.

If it is a timber frame house, the area around the pipe must be masonry, which is also expensive.

No, that is not necessary - see my previously posted offer keyword Coolblock. I am attaching a picture of the house penetration to the outside and see that I did not describe a penetration in the offer. So: The chimney of the main apartment has one penetration through the house wall, one through the flat roof over the terrace, and one through the tiled roof. Cost €3568.
