With hybrid technology, DuoWIN combines heating with wood and pellets in one boiler.
The unit is designed to allow users to either use logs or pellets when its intelligent fuel switching detects when the wood gassifier is in burnout, and switches to pellet operation either automatically or at a set time.
The DuoWIN system is based on two existing Windhager models – the LogWIN Klassik and bioWIN 2 pellet boiler.
