Air Ventilation

To have a soothing sauna, there should be a proper mixing of hot and cold air inside the sauna room.

Another reason for ventilation is to draw air around the heater and to move the heat to the farthest part of the sauna. The positioning of the inlet and outlet vents may vary depending on the design of the sauna room or preference of the owner.

The inlet vent may be installed on the wall directly below the heater (as shown on the picture).

When using the mechanical ventilation, inlet vent is placed at least 60 cm above the heater or on the ceiling above the heater.

Through these positions, the heavy cold air that is blown into the sauna is mixed with the light hot air from the heater, bringing fresh air for the bathers. The inlet vent must have a diameter of 5-10cm (recommended).

The outlet vent should be placed diagonally opposite to the inlet. It is recommended that the outlet vent is placed under the bench in a sauna as far as possible from the fresh air vent. It may be installed near the floor, or led outside through a pipe from the floor going to a vent to the sauna ceiling, or under the door (to the washroom). In this case, the sill slot must be at least 5cm and it is recommended that there is mechanical ventilation in the washroom.

The size of the exhaust should be twice that of the inlet.
