Benefits of wood chip heating systems
Highly efficient combustion
The burner is the heart of a wood chip heating system. KWB developed the unique crawler burner using robust cast technology originally derived from large industrial systems. During continuous operation, it adapts automatically to the relevant fuel quality, ensuring particularly efficient and economical combustion. The wood chips are produced from regional wood with short transport routes, helping to keep heating costs low.
Easy installation and a long service life
Thanks to their modular construction, KWB wood chip boilers are easy to install and can be brought into confined boiler rooms without difficulty. They operate fully automatically and handle cleaning and ash removal independently. Between service intervals, only the ash container needs to be emptied. The systems can also be controlled and maintained remotely using a smartphone, tablet or PC. A KWB wood chip heating system provides high efficiency, dependable operation and a long service life.
Quiet and clean heating
KWB wood chip heating systems also offer a high level of acoustic comfort. An automatically filled intermediate hopper allows the boiler to draw fuel directly from the hopper during much of its operation, meaning the main discharge system remains idle and noise is kept to a minimum. The systems can also be equipped with the optional KWB dust filter E Plus, which ensures particularly low fine dust emissions even where fuel quality varies.

What does a wood chip heating system consist of?
KWB crawler burner
The KWB crawler burner consists of high-alloy, self-cleaning cast grate components. During continuous operation, the robust grate adapts automatically to the relevant fuel quality. Optional fuel recognition plus optimises combustion control accordingly, allowing wood chips or pellets to burn efficiently and completely. No unburned residues remain in the ash, fuel is not wasted and heating costs are reduced.
Stoker screw
A stoker screw supplies the combustion chamber reliably with fuel. It ensures a consistent fuel supply and therefore an efficient and clean combustion process.
Storage and discharge
Our systems for large storage rooms are designed for high-output heating systems. The conveyor system for wood chips or pellets is adapted individually to the structural conditions, regardless of whether the storage room is located beside, above or below the boiler room, further away or outside the building. KWB stirrers with diameters from 2.5 to 5.5 metres ensure that the available storage space is used effectively.
Storage systems
Wood heating systems operate particularly efficiently when combined with buffer storage tanks. These absorb excess heat, store it and release it to the heating system or domestic hot water supply when required. With KWB, you receive everything from a single source, from the boiler and combustion chamber to the matching accessories. Our premium products provide a high level of operational reliability and are made in Austria.
