Biomass boiler can burn logs or wood pellets
Euroheat now offers a range of biomass boilers that can burn logs or pellets and switch between these fuels automatically. The TDA Thermodual range is made by SHT-Austria and available with outputs from 15 to 40 kW. These boilers can be fired with logs or other dry wood manually; when this fuel has been used up, the boiler will automatically switch over to its built-in pellet hopper.
The hopper can hold up to 130 kg of pellets, giving automatic operation for up to 26 hours, representing four to five days’ usage. Longer periods of operation can be achieved by connecting the boiler to a remote pellet store with an automatic screw feed or an air-powered delivery system.
Ignition is automatic. Pellets are first ignited, and then any wood in the log chamber is burnt. The grate is self cleaning, and several operating cycles can be completed before the ash pan needs emptying.
