It is possible to install pellet burners of different producers, like Ariterm or Ala-Talkkari to wood chip boilers, and this ensures heat and domestic hot water with minimum maintenance and time. For maintaining burners, there are separate maintainance hatch on the boiler.

The fuel can be P45, M30 wood chips with a fraction of 45 mm and humidity of 30%. Likewise, it is possible to heat with pellets, grain, sawdust and wood shavings. Wood chips are stored in a special container located in a boiler plant or in case of larger boilers, outside the boiler plant. In case of BIO-35 and 50, 440-litre or 950-litre indoor containers with mixing wheels are used.

In case of BIO-80, 100 wood chips are stored in scraper or spring scraper containers which volume reaches up to 15m³. It is also possible to establish a wood chip storehouse which enables to store much more fuel.

The boiler’s efficiency exceeds 90% and requires minimum maintenance – the wood chip boiler is equipped with automatic ash isolation system that helps to collect ash to the ash box located in a boiler plant or further in a larger yard container.

In addition, it is possible to order a pneumatic cleaning device for a boiler that enables to clean the boiler automatically and efficiently.
