A biomass heating specialist has just launched its brand new combination biomass boiler. With hybrid technology, the device combines heating with wood and pellets in one unit. This sophisticated biomass boiler system allows users to either use logs or wood pellets and its intelligent fuel switching detects when the wood gassifier is in burnout and switches to pellet operation, either automatically or at a desired time.

The DuoWIN system from Windhager is based on two previously proven biomass boilers, the compact log boiler LogWIN Klassik and the recently launched compact BioWIN 2 wood pellet boiler, and thus takes up only 4.19m² of space.

The new boiler is available as either a comfort or energy optimised variant. The PowerBoost function can meet short-term higher heat demands up to 56kW. With the energy optimised version, pellet operation is up to 25% more efficient than conventional combination boilers. Available in four models from 33 kW – 56 kW output, the heater has a filling volume of 145 litres for 50cm split logs and 164 litres of wood pellets, the feed for which can be either manual or fully automatic.

Within the boiler there are two independent heat exchanger systems which ensure maximum reliability yet with a smaller space requirement than that of other combination solutions. Both the wood combustion chamber and the stainless steel pellet burner bowl are not wearing parts and are included in Windhager’s five year warranty. The ignition elements ignite silently, are robust and maintenance-free and are also included in the warranty.

One special feature is that you can upgrade anytime to dual fuellling if you have Windhager’s LogWIN Klassic log boiler as this is ‘pellet-ready’, meaning that the pellet boiler BioWIN 2 can be added at a later date.
The LogWIN Klassic has a large filling chamber opening for easy access with logs, and has a detachable ash pan for easy removal. The log boiler also features automatic ignition meaning that no kindling is required to start the boiler burning.

The device has very long maintenance intervals. Its robust stainless steel burner with LowDust technology burns so cleanly that the pellet boiler is well below the international emissions standards.
