Ventilation in the bath and sauna

Bath ventilation: purpose and features

When building a bath, it is necessary at the initial stage to take measures to ensure proper ventilation of the bath in order to achieve:

• high temperature indicators and air humidity in the steam room;
• enough oxygen;
• preservation of the bath from fungus and mold.

Types of ventilation in the bath and sauna

There are two types of ventilation: natural and forced.

In the first case, the difference between the air inside and outside the bath is used: warm and humid air rises and is removed into the hood, and cold and dry air from the street enters through the inflow. To regulate air exchange, holes are made for air inflow (at a height of 30 cm from the floor next to the stove) and exhaust (on the opposite side below the ceiling by 15-25 cm). The dimensions of the holes depend on the volume of the steam room: per cubic meter. meter area, the size of the holes should be 25 sq.cm. Depending on the location of the outlets, we will be able to control the direction of the air heated from the boiler. Ventilation openings (windows) require latches or doors to prevent gaps from remaining.

There is only one good thing in this approach – ventilation will not require the cost of buying and operating equipment, such as fans.

There are more negative consequences: condensation forms due to low air exchange rate, ventilation depends on weather conditions, the tree begins to rot, fungus and mold grow.

Forced (mechanical) – indispensable for baths with more than five visitors, for baths with a pool, and ventilates the room faster than natural.
Three subspecies of forced ventilation of the bath are known:

• supply air – air is forced in, and removal occurs naturally through the outlets;
• exhaust – the air is removed forcibly, flowing in a natural way through the inlets (not recommended for a steam room, because a lack of oxygen is detrimental to a person);
• supply and exhaust – air is forced in and out (in large baths).

Mechanical ventilation does not depend on the temperature and weather outside the window, keeps the building from excessive moisture, condensation, mold and fungus, but its arrangement and use entail constant expenses. How to fix the situation?

Economical and efficient ventilation systems in saunas

Ventilation using inexhaustible solar energy is a subspecies of forced ventilation. Solar energy is used to operate fans, while air masses are heated in parallel – while we save electricity and solid fuel. For this method of ventilation baths use solar collectors. They are connected to fans that are located in the supply and exhaust systems. Russian manufacturers provide ready-made designs of solar collectors. Equipment costs pay off in 5 years due to savings on electricity and firewood costs.
