This year, in the summer of 2022, a new Brunner WF 33 insert was installed in my current tiled stove (36 years old) by the specialist company Schömig from Höchberg/Würzburg. Batch no. C011.002-05.000.787010. With the start of the heating season, our new WF 33 burns almost every day and we are every time more and more enthusiasti...

Competent service technicians can no longer be taken for granted today
Jochen Gräve, Niederwerth: Good morning, Yesterday, between 4:00 and 5:30 p.m., your service technician Mr. Kieswimmer changed the brackets on my masonry heater door and checked and readjusted various settings on the EOS.

Michael Schmidkonz: Dear Ladies and Gentlemen, We have bought a Brunner HKD 5.1 tiled stove. It is a top class product. Whether for ignition, continuing to heat or keeping embers burning - simply outstanding! With kind regards from Tirschenreuth Michael Schmidkonz

Our tiled stove was put into operation 37 years ago. Our chimney sweep is very enthusiastic. He has also already taken measurements with my consent. Top values

Better some euros more for the brand quality of BRUNNER
Ralf Lenz: Dear Ladies and Gentlemen, The chimney sweep just came. He wouldn’t believe that we had left our stove burning all winter. It turns out that it's better to spend a few euros more on brand quality such as a Brunner stove than to buy cheap junk. It pays off in the long run - and the environment is happy too :-) Cordia...

Corner fireplace of BRUNNER is the eye-catcher in the living room
Dr. Buch, Tutzing: Dear Ladies and Gentlemen, With the installation of the corner fireplace Architektur-Eck 38/86/36 from Brunner, our newly created living room has become a real eye-catcher. Without being obtrusive, it is a compelling fireplace installed in steel. The convincing quality-oriented technology and the perfectly...

After we got a new gas condensing boiler in 2017, Kachelofen Schulz from Rastatt-Rauental built a water-bearing heating fireplace for us at the same time. We are still totally enthusiastic about this combination, Mr. Schulz also showed us wonderfully how to fire optimally and burn wood effectively. Now we have obtained another B...

We heat the first winter with a stove installed by stove builder Stefan Hock from Bessenbach. Not only does the stove look great and fit perfectly into the picture, it also makes you really warm, and with far less wood than we needed before.
