Wood pellet biomass heating system manufacturer Windhager has added to its range of wood pellet boilers with the BioWIN Plus

The unit comes in four outputs: 10kW, 15kW, 21kW and 26kW, and is suitable for applications such as blocks of flats, hotels or public buildings. Where higher outputs are required, two or three boilers can be linked, producing an output of up to 78kW. The BioWIN technology features modulated operation which means it can be controlled to provide anywhere between 30% and 100% of the total capacity, avoiding the on/off operation of some boilers and the need for a buffer tank. The units have fully automatic pellet feed and ash removal.
