Draught damper

Pellet boilers require stable draught conditions to ensure consistent and efficient burning of wood pellets. As the draught is affected by temperature, weather and wind, a draft hatch must be fitted into the boiler flue inside the boiler room air. This ensures:
  • more stable draught and flue gas temperature
  • reduced stoppage losses
  • ventilation of the flue
  • drier flue gases, which reduces the risk of condensation
