Combustion of pellets is ensured by the burner made from the best quality refractory steel. Burner operation is fully automatic. Boiler body is welded from the high quality boiler steel of 6 mm thickness, ensuring long life. Refractory concrete parts are made from the best quality material, strengthened by the refractory reinforcement. Furthermore, the most strained nozzle is treated by a special refractory cast iron, prolonging the boiler’s life, because it is resistant to scoring.
Big volume of the feeding chamber
To provide the high comfort, the boiler is equipped with the feeding chamber of big volume. Thereby there is an option of the continuous burning at full output for 6 hours. Moreover, if the boiler detects signal for heating, it can automatically start the pellet burning process, after the wood in the wood-gasifying boiler part burns out, without any action into the boiler operation. Thereby you can easily use advantages of the cheapest heat source – wood, in combination with the comfortable and also very cheap heat source – pellets.
High Efficient Combustion
Boiler achieves particularly high efficiency, exceeding 90,5 % by wood and 90,4 % by pellet combustion. This has been reached also thanks to the vertical tubular exchanger with extraordinary heat exchange area and special, automatically moved turbulators. Thereby is the declared efficiency ensured for the whole boiler’s life.
The boiler is equipped with the integrated aftercooling circuit, connected to the cold water and ensuring safe cooling down of the boiler in the case of its overheating. The emergency thermostat is the next safety element. In the case of overheating, it stops electrical power supply into the all electrical parts of boiler, except of the pump to cool the boiler down as soon as possible. If the boiler gets overheated, the electronics warns the user by a sound signal. If the boiler works under the pellet mode, it is able to lock the main door by the electrical lock, not to leave the door unperfectly closed or partly open. The boiler has a double protection against the backward burning – the high efficient turnstile feeder and the self-extinguishing hose.
Boiler cleaning is very easy. Turbulator and pellet combustion chamber are cleaned automatically. Boiler electronics can be supplemented with the additional modules, enabling control of accumulation tank, mixing circuits, D.H.W. storage tank, solar panels and other heat sources.
Boiler state can be also controlled via the LAN internet connection. Electronics is able to provide a month record of the information about operation.
