Robust and economical heating
KWB wood chip heating systems are multi-talented: They burn various wood chip qualities efficiently and with low emissions. Our wood chip boilers work fully automatically and cost-efficiently.
KWB wood chip boilers are the fully automatic alternative to oil or gas heating systems. They are built according to industry standards. Thanks to the robust KWB crawler burner, they can easily manage various fuel qualities. Their operation is very cost efficient.
What do wood chip boilers consist of?
- A heat-resistant combustion chamber where the fuel is burned
- A stoking screw that sends fuel into the combustion chamber
- An ash extraction
- A self-cleaning heat exchanger which ensures that the generated heat is transmitted to the heating water
A wood chip boiler must include both a storage room for the wood chips and an extraction system that transports the fuel directly to the boiler. At KWB, you get everything from one source. Our quality products are operationally safe and also guaranteed Made in Austria.
How does the KWB Multifire work?
The large power range of 20 to 120 kW combined with highest fuel flexibility makes it possible to deploy the new KWB Multifire wood chip or pellet heating system in a larger single family home, in commercial facilities and including smaller district heatingWatch the video
Highly efficient and economical combustion
The core of a wood chip boiler is its burner. KWB has developed a unique crawler burner manufactured with cast technology. This type of system was originally used in large, industrial combustion systems.
The fuel is burned in a highly efficient and economical manner thanks to the crawler burner’s continuous operation, which makes it very flexible and able to adjust automatically to the fuel quality or characteristics. It burns only as much fuel as is absolutely necessary. The wood chips are produced from domestic wood that is regionally sourced. This guarantees short transport paths, and it also keeps heating costs low.
Comfortable and safe installation and operation
KWB wood chip boilers are easy to install. Due to their modular design, they are easy to transport and place even in tight heating rooms. They function fully automatically, starting with the fuel supply from the fuel storage all the way to the heat provision. They are also self-cleaning and extract the ash automatically. Between service intervals, only the ash container, which is divided into two parts in the optional comfort version, must be emptied out. In addition, the heating system can be controlled and maintained remotely using smartphone, tablet or PC. KWB wood chip boilers are characterised by their outstanding efficiency and operational reliability and their long service life.
Quiet and clean heating
With a KWB wood chip heating, there is also no need to worry about excessive noise. The central heating can be equipped with a hopper. It is automatically filled with wood chips from the storage room. While heating, the boiler can usually pull wood chips from the hopper. In this case, the large extraction system does not even need to run, which means it is completely noiseless. KWB wood chip heating systems can be additionally equipped with the dust filter E-Plus. This ensures that the combustion remains nearly fine dust-free even with fluctuating fuel qualities.
KWB wood chip boilers are available in the range of 20-300 kW. They are used both in multi-family houses, in agricultural companies, but also in commercial and hotel businesses. Heat suppliers also rely on wood chip heating systems.
