Boiler features
  • The boiler BENEKOV C 250 demonstrates seasonal dust emissions of mere 3 mg/m3 in coal combustion (the Ekodesign standard requires 40 mg/m3).
  • The boiler utilizes one universal burner which can burn both brown coal and wood pellets.
  • The thickness of the metal plate of the combustion chamber walls is 8 mm.
  • The control unit Siemens is capable of controlling two independent heater power circuits and allows for distant online control.
  • Boiler draught is regulated by an outlet fan according to a pre-set parameter of underpressure in the combustion chamber.
  • The boiler consumes for its operation 130 - 430 W of electric energy, including all secondary devices.
  • BENEKOV C 250 may be delivered also in a form of a mobile boiler-room, which is connected to the interchanger inside a building through an external energy channel.
