Problem of chimney dimensioning - panoramic chimney as a room divider

Buy yourself an ash vacuum cleaner. I can only recommend it :)

Can you recommend a specific one? We also have one with 9 kW. A Camina S14 or 15. We really don't have much heat storage mass. Nevertheless, we don't experience the effect reported to us by friends who have a stove from the hardware store. They apparently always reach sauna-like conditions when they turn on the stove. For us, the temperature increases by a maximum of 4 degrees. So from 21 to 25 degrees. However, we also have a large open area around the fireplace (about 70 sqm with a ceiling height of 2.75m).

Take a look at the contura I51 models. They are not too big in size or in terms of performance.

I bought it at OBI. It cost 39,-. I'm glad I never have to clean with a shovel and broom again and stir up ash :-)

Well, I don't do that either. I always take a small thin but wider piece of wood and scrape the ashes into the middle. There is a catch tray under a grate there. And after lighting it a few times, I take the tray out and empty it. Only a vacuum cleaner would be really handy to suck up dirt in places that are hard to reach or where the dirt falls where you don't want it.

With the ash vacuum cleaner, you simply vacuum clean and never have to touch the ash container again. Additionally, you can also use it to well vacuum the sealing lips, which always have ash residues. If you remove the filter, you can also vacuum medium-sized coal pieces ;)

Oh dear, I always do it with the regular vacuum cleaner, at least the door and whatever falls nearby. Is that a problem?

I change the ash in the stove about every 8 weeks. That is usually enough, since the ash also burns up again and again, I've learned about 8 times. And you should never remove all the ash, about 20 percent should remain in the stove.
