Log wood boilers from BRUNNER are high-quality, durable wood gasifiers. They are fully developed and manufactured in Germany. All key components are made of cast iron and produced in-house. Wood gasification boilers have a high efficiency level. Their unique, patented combustion chambers make it possible to achieve extremely low emissions — not only in type testing but also in real-world operation during recurring measurements — thanks to a gasifier fan that ensures efficient post-combustion.
The combustion process in a log wood boiler begins in the filling chamber. In the lower section, the pyrolysis process starts, initiating the change in the wood’s physical state. In the post-combustion chamber, with precisely controlled oxygen supply, complete combustion takes place. The hot gases then flow into the boiler’s heat exchanger, where the heating water is warmed. Operation of the log wood boiler is simple and intuitive, controlled via a modern glass touch display.
Extra safe
BRUNNER log wood boilers feature an automatic door locking system. This prevents accidental opening during combustion, which could otherwise cause flames or flue gases to escape as a flashback. And what happens during a power outage? There’s an emergency power supply for that as well: the NV 500/1000 is a special charging inverter that, together with a battery, ensures that combustion in the wood boiler can be safely completed even in the event of a power failure.
Conclusion
Heating with wood is environmentally friendly and saves fossil fuels. Thanks to their design, modern BRUNNER log wood boilers are also extremely efficient while keeping emissions very low.
Expert advice
The modern log wood boiler stands out for its low emissions and technical innovations that not only save costs but also make the boiler safer.
