    BRUNNER Water-bearing system stoves

    BRUNNER water-bearing system stoves are the perfect combination of long-lasting heat storage and modern hot water generation. While the ceramic storage stove releases gentle radiant heat for many hours, the integrated heat exchanger simultaneously supplies the heating system with hot water – an ideal way to support the central building heating system.

    As a modular kit, it guarantees quick installation. With precisely manufactured components and flexible design options – such as exposed concrete, plaster, or ceramic – the stove blends seamlessly into any living concept.
