Ventilation in the sauna should provide at the same time a sufficient amount of fresh air and high temperature indoors. More often than not, proper ventilation in the sauna runs on natural draft.
Natural ventilation in the sauna
The main task when installing ventilation in the sauna with your own hands is to ensure the replacement of hot exhaust air with fresh. But the trick is that the hottest air, located under the ceiling of the sauna, must remain indoors. Due to this, a high temperature is maintained. Thus, the movement of air in the sauna should be carried out from the supply pipe to the exhaust valve.
Ventilation scheme in the sauna
Before you make ventilation in the sauna, you need to calculate which of the existing types is more suitable: forced, natural or combined.
The operation of forced ventilation is associated with the consumption of electricity, so most owners of saunas are equipped with combined or natural draft. With a combined ventilation scheme, a fan draws air in the sauna. The inflow is provided by natural traction. Often manual control of air flow is inconvenient.
The presence of the furnace in the steam room makes it easy and without extra costs to equip the ventilation in the sauna with your own hands.
The subtleties of arranging ventilation in the sauna with your own hands
One of the most difficult moments in organizing proper ventilation in the sauna is selecting a place for the exhaust valve.
It is the place of the valve that affects the microclimate parameters in the steam room to a greater extent. The optimal location of the valve is opposite the furnace. 25-30 cm should be retreated from the ceiling. Using the gate valve, it is easy to control the air flow. But with it, heat will also be blown out of the sauna. To prevent this, the sauna ventilation circuit provides two valves. The first, as described above, the second under the shelves. While people are in the steam room, only the lower valve is opened. It connects to the pipe leading to the upper valve. When the bottom is open, air partially flows out of it, and partially remains in the room, rising up. Air is supplied through the supply duct.
Before starting work, you should calculate how to make ventilation in the sauna. The cross section of the supply pipe must be 15 percent smaller than the exhaust section and 20 percent larger than the chimney section. The exhaust pipe is discharged through the roof, a diffuser is installed on top.
