Wood gasifier

Efficiently recovering thermal energy

Wood is a natural, domestic raw material. Compared to oil and gas, it is inexpensive and not subject to large price fluctuations. That is why more and more people choose wood heating. Wood gasification boilers achieve the highest heat yield.

Wood boilers by BRUNNER are high-quality, durable wood gasifiers. They are completely developed and built in Germany. All important components are made of cast iron and come from our own production. Wood gasification boilers have a high degree of efficiency. The unique and patented combustion chambers make it possible: lowest emissions not only in the type test, but also in practice by recurring measurements, because the post-combustion is more efficient due to a gasifying blower.

The combustion process of the log boiler starts in the filling chamber. In the lower area, the pyrolysis process is started and the change of the aggregate wood state is initiated. In the afterburning chamber with targeted oxygen supply, complete combustion takes place. The heating gases flow into the boiler with heat exchanger and the water is heated. The operation of the log boiler is simple and intuitive, it works via a modern glass touch display.

Higher safety

BRUNNER log boilers have an automatic door lock. Accidental opening during combustion, with the risk of flames and heating gases escaping as a deflagration, is impossible. And what happens in the event of a power failure? There is an emergency power supply for that, too: The NV 500/1000 is a special inverter; in combination with a rechargeable battery, in the event of a power failure it stops the combustion in the wood-fired boiler without disruption.

Specialist tip

The modern log boiler shines with low emissions and technical innovations. It is not only cost-efficient but also provides safety.
