Brunner BKH 5.0 Tunnel 50-122 ST KT green

The BRUNNER ‘Green’ range of wood-burning stoves sets new standards in stove technology by offering a unique, patent-protected hob firing system. This innovation ensures a perfect flame pattern while minimising emissions, which are well below all current limits. The ‘Green’ and ‘Green+’ fireplaces from BRUNNER are therefore pioneers in sustainable, environmentally friendly heating technology.

Main features of the BRUNNER ‘Green’ fireplaces:

• Patented trough firing: The specially developed combustion chamber geometry is a major innovation. This shape enables efficient and clean combustion, as the primary air flows laterally into the combustion chamber recess and the secondary air is supplied from above as disc scavenging air. The grate and ash box are completely eliminated, which makes maintenance and handling easier.
• Clean burning without laboratory conditions: A particularly noteworthy advantage is that BRUNNER fireplaces do not only achieve their low emissions under laboratory conditions. With the correct operation and the right fuel, verifiably clean emissions can also be achieved in domestic use. This makes it possible for everyone to heat ‘green’ at home.
• Green+ with catalytic converter and combustion control: To achieve the highest quality level, versions with an integrated catalytic converter and intelligent combustion control are available. These ensure even more efficient and environmentally friendly combustion.
• Optimised air flow: A front control element can be used to set the optimum ratio of primary and secondary air, which has been determined on the basis of test bench tests. This precise air control helps to optimise combustion and minimise pollutants.

BRUNNER's ‘Green’ technology shows that efficiency, design and environmental awareness can be harmoniously combined. These fireplaces not only offer a visually appealing and powerful fireplace, but also actively contribute to reducing emissions, making them a forward-looking choice for anyone who wants to heat their home sustainably and responsibly.
