Or affectionately called "der Backenzahn" (the molar tooth)

The body of a cast iron wood stove is made of the high-quality material cast iron. It has the highest thermal conductivity and many more advantages compared to a steel-made wood stove: a cast iron wood stove does not deform. The material is heat-resistant, robust and durable.

Ideal with top to warm up and holding
Also optional available with an upturned pipe
Ash pan made from stainless stell for easy cleaning
Grooved look

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...

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  
Kehl Herbert
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.

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...

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...
