Additionally, features that characterize the lower combustion are:

  • lower emissions,
  • better fuel afterburning
  • lower exhaust gas temperature at the boiler outlet
  • higher efficiency exceeding 86%

Use of this boiler does not require electricity because the boiler works by using natural air flow, and temperature control is carried out mechanically by means of a tumble flap wheel mounted in the door bottom or using draught regulator. An additional feature of this boiler is the possibility of regulating the secondary air stream. Series boilers DS has a built-in cooling coil, which allows for installation in closed systems.
