Brunner System Fireplace BSK 42-42 DT green
BRUNNER quality with a customisable fireplace surround
A system fireplace is installed when atmosphere is the primary requirement. The design, fuel quantity and the associated heat output are matched to this.
System fireplaces are also known as ‘rapid reaction stoves’ due to their heat output. The heat is released during combustion. The heating effect results from the combustion chamber radiation through the large viewing window and the hot air.
There is no simpler or cheaper way to build a fireplace or stove. Precisely dimensioned moulded parts made of thermal concrete enable quick installation. Components and moulds are designed so that the fireplace system can be installed in a minimum of space, taking into account function and safety. Only components used in handcrafted stove construction are offered as a ready-made kit. An original BRUNNER heating insert is installed in all versions.
The panelling is available in different quality levels:
- In the functional version with a thermal concrete casing, untreated and deliberately left in exposed concrete as an architectural element.
- Or a hand-finished surface that is painted, plastered and decorated with ceramic elements.
The cladding elements can also be extended in height. Room-height versions have thermal insulation to the ceiling and on-site hot air outlets. If the system cladding is to be extended structurally, all ideas and concepts can be realised with BRUNNER fireplace construction panels. The distance to the extension wall can be minimised with heat protection plates (accessories) fitted to the fireplace insert.

*EASY-LIFT’ - AN INVENTION FROM BRUNNER.
There's no easier way to open a sliding door!
This is our solution for a smooth-running and durable disc mechanism. When opening, the door lifts from the stove body and slides upwards. Only when it is closed does the door and its sealing surface move automatically towards the fireplace body.
This door guide, which is unique to fireplaces, is easy to operate and ensures a durable and permanently tight door seal.
