ECOTWIN – Combined wood and pellet unit
ECOTWIN is a combined unit for combustion of wood manually and pellet with an automatic pellet burner. The boiler lower door is equipped with a mounting flange for installing a pellet burner, as well as an air door actioned by a chain thermostat regulator for wood combustion.
An additional door can be installed for easy change between wood and pellets (optional). Depending on the fuel used, the corresponding door is being closed.
ECOTWIN is offered as a complete pellet unit including the boiler, pellet burner and feeder. The silo volume can be chosen according to the desired autonomy.
