Preheating supply air chimney

härmä-air-AIR

Air IN supply air chimney has been developed to convey fresh and preheated combustion air brought from outside, directly for the burning in the fireplace. Thanks to the air circulation, fire safety is improved, which means that only minimal safety distances are required for the chimney.

By means of closed cycle, exiting flue gases heat the supply air to temperatures close to 100°C, improving the efficiency of the fireplace. The chimney suits excellently for houses where the conveying of combustion air has not been taken into account. This chimney allows more options for the placing of fireplace, and the solution helps to solve the most common problems in densely built houses, such as the adverse draught caused by the range hood and the built-in vacuum cleaner.

Some benefits of Air IN chimney:

  • The fireplace will have fresh, preheated combustion air through the chimney.
  • The fireplace is fully independent of other ventilation solutions used in the building.
  • Preheated combustion air will make the burning in the fireplace more efficient.
  • Improved fire safety, thanks to air circulation.
  • No other separate make-up air inlets are required in the structures of the dwelling.
