Pellet heating boiler DRACO DUO 50 kW

Pellets heating boilers DRACO DUO is stipulated for heating with solid fuel as in automatic mode, so traditional mode. The constructive solutions applied in the manufacturing of the boilers DRACO DUO, provide for a high safety of boiler operations, convenient exploitation and comfort owing to the operation in the automatic mode, as well as universality of fuel choice. The construction of the boiler allows to heat with pellets and coal fraction up to 25 mm in the automatic mode, in the traditional mode with coal and wood. The upper combustion chamber (the traditional mode) is provided for the heating with solid fuel in emergency situations, it is not stipulated for exploitation throughout the entire heating season. The heat exchanger of the boiler is manufactured of 8 mm thick certified boiler steel. The boiler is equipped with a modern, very simple in application regulator providing for over 30 functions, including the automatic regulation of modes depending on weather conditions, as well as it is possible to install a room thermostat. If it is necessary, it is possible to equip the boilers of 15 – 35 kw capacity with a rotating burner. The pellet heating boilers DRACO DUO are characterized by ecological and high efficiency combustion of fuel, achieving even 86%. With a wide range of boiler capacities it is possible to heat a detached house, as well as a block of flats, recreation premises, shops, etc.
