Brunner System Oven BSO 2 Tunnel
BRUNNER quality with a customizable fireplace shell
The BRUNNER BSO system stoves are a well thought-out and cost-effective solution for efficient heating with an attractive appearance. With their modular kit system, they offer quick installation and at the same time a wide range of design options, from modern exposed concrete to individually designed ceramic surfaces. Unusual plaster structures are also possible, allowing the BSO to be perfectly integrated into different living styles.
Special features of the BRUNNER BSO system stoves:
- Attractive thermal concrete: The system stove impresses with its simple and elegant concrete look, which fits perfectly into modern living concepts.
- Alternatively, ceramic surfaces or individual plaster designs are available.
- Efficient heating technology with a tiled stove effect: The cast-iron tiled stove insert is equipped with a storage mass through which hot gas flows. This enables long-lasting heat emission - even after the fire has gone out.
- Thanks to the “slow reaction principle”, the stove stores the heat effectively and releases it evenly into the room for hours.
- Flexibility: For additional efficiency, the system stove is also available as a boiler appliance, which can be ideally integrated into a central heating system.
- Easy installation and cost control: The kit reduces installation time and overall costs without compromising on quality.
