The DuoWIN offers an intelligent combination of the heating benefits of two biomass technologies. This hybrid boiler unites inexpensive split-log heating with the convenience of heating with pellets in a single device. For a quick blast of extra warmth, the PowerBoost function sees the split-log and pellet units heat up at the same time for an output of up to 56 kW. With the DuoWIN, pellets can either be fed in manually or automatically. What’s more, the DuoWIN pellet unit can even be retrofitted further down the line with the pellet-ready model of the LogWIN Klassik split-log gasification boiler. Up to 25 per cent more efficient when using pellets PowerBoost function for peak performance pellet ready - pellet unit can be retrofitted Intelligent fuel switching The hybrid boiler's automatic fuel changeover detects if the wood gasifier is in burnout. If there is too little energy available in the boiler or heat exchanger, the unit will change to pellet operation either automatically or after an individually adjustable time. Individual pellet feed The DuoWIN can be equipped with either a manual or fully automatic pellet feed. Two separate heat exchangers Both independent heat exchanger systems guarantee maximum security. The wood combustion chamber and the stainless steel pellet burner are not considered wearing parts and are included in the guarantee. More power or more efficience The DuoWIN is available as either a comfort or an energy optimised variant: the PowerBoost function enables short term higher heat demands up to 56 kW. Thanks to the EnergySaver, the DuoWIN's pellet operation is up to 25 % more efficient than conventional combination boilers.
