How to make a hood in a steam room bathhouse do it yourself

An extract in the bath is necessary and everyone understands this. At the same time, various criteria of need are evaluated, among which there may be both dampness and stuffiness, and even carbon monoxide. Later we will briefly go over all the consequences of insufficient ventilation, but now we note that literally everyone can do high-quality ventilation in the bathhouse with his own hands. The specific design will depend on the type of steam room, furnace, location of the heating zones. But in general, the ventilation system of the bath is not difficult.

What causes the lack of ventilation in the bath

Whatever structure is involved, the first thing that guarantees the absence of a hood is a reduction in service life. Buildings in general, if a wooden blockhouse is considered. And the finishes in the steam room or bathhouse as a whole, if it is made as a reinforced concrete structure with a wooden coating of the walls inside. In addition, a missing or malfunctioning hood made in the steam room can cause the following troubles:

• poisoning vacationers with products of their own breathing;
• damage to the lungs with carbon monoxide if it is released due to an insufficient flow of fresh air to the furnace;
• lack of comfort, because the steam room rises extremely quickly in temperature and humidity.

In addition, the hood must be done efficiently to guarantee drying of benches, flooring, wall covering after rest. This will ensure the absence of mold, fungal infections, which will not only extend the life of the tree, but also will not worsen the health status of those who relax in the bath.

Mold and fungal crops are the most dangerous things that can happen in a bathhouse. Inhalation of spores has an extremely negative effect on health. Therefore, if the bath is a log cabin with a wooden floor, the hood should be extremely effective. In addition, even during the construction of the building, it is necessary to provide ventilation of the floor.

What are the requirements for an extract in the bath

Although it is relatively easy to make a hood in a steam room with your own hands, you must ensure that the following situations do not occur:

• the flow of incoming cold air into the steam room directly falls on vacationers;
• there are clearly defined zones with low temperature flows;
• the hood works so that part of the room is much hotter than the rest of the area.
• To avoid such troubles, just when designing a hood in a bath with your own hands, you should adhere to these rules:
• intake ducts are located in the floor area;
• if possible, preheating of the incoming stream should be carried out, for which it is better to place the intake channels near the furnace or other used heating devices. This will not only provide heating, but also guarantee the supply of a sufficient amount of oxygen to the furnace if an open flame is used;
• the exhaust ducts must be adjustable so as not to allow a situation where the hood made in the steam room cools the room extremely quickly.

When planning the supply and exhaust ventilation in the steam room and bath, you must either be able to change the heat transfer rate, or change the air in the steam room 2-3 times per hour.

An ideal, always existing channel for extracting air in a bathhouse with an oven is its firebox. Therefore, it is important to supply enough fresh air to the combustion zone. Heated gas rises through the exhaust pipe and is thrown out.If the draft is strong enough, you can arrange the ventilation grilles at the bottom of the front door in the steam room. This is the easiest hood you can do yourself.

Air flow patterns

Below is a diagram by which air moves in the bath when it enters from the outside and exits through exhaust ducts or openings.

The above figures show that the above principles are observed:

• low-temperature incoming air comes from below or is preheated, passing near heat sources;
• The furnace furnace and its exhaust pipe can be an excellent outlet channel.

In practice, when the exhaust system in the steam room is created by oneself, the circuit shown in the upper right corner of the figure is tried on. This type of ventilation has a number of advantages:

• exhaust openings or channels can be equipped with mechanical blowers that allow flow control;
• the inlet channels do not require the installation of pressure equipment, in which case the flow of cold air will be smooth, and the amount of cold can be easily regulated by a simple damper.

In addition, the air line is smooth, as is its heating. A good atmosphere with a constant temperature throughout the volume is formed in the steam room. It is advisable to place the inlet channels for the intake of cold air under the benches to ensure that the bodies of vacationers will not be sharply cooled.

What mechanical means can be used

When a hood is being built in a bathhouse or steam room, you can do with simple dampers and grilles to regulate air flow. However, the use of mechanical and electrical devices is not as difficult and costly as it seems. When you build a ventilation system with your own hands, you can apply:

• exhaust anemostats, which will ideally fulfill their functions both during the natural circulation of air masses and when using fans;
• simple electric fans isolated from moisture show excellent results. There are few such devices, ideally at two points located in the upper corners of the wall;
• if you want to save money, you can arrange simple fans without moisture protection outside the steam room, where they will work in normal humidity. To collect condensate from incoming from the fresh air, nets are used, which are folded inside the ventilation pipe. In order for the formed water to be removed, a vertical section of the channel is usually made with the bottom open;
• very simple and not very expensive electronic temperature control circuit. Its task is to work in two modes, ensuring the inclusion and constant operation of exhaust fans, as well as their inclusion when the specified temperature level is exceeded and off when it falls.

As a result of simple work, you can make a high-class sauna, where all modes are literally set with one adjustment knob on the wall.

Anemostats can be successfully used to form a two-point exhaust channel, which simultaneously captures moist air close to the floor surface (or from under the grating) and in the ceiling area, where the air is overheated and saturated with carbon dioxide. The diagram below shows how a well-ventilated bath is arranged, which can be quickly dried and at the same time, by adjusting the anemostats, achieve the desired balance between air flows at floor level and close to the ceiling.

Conclusion

In conclusion, it should be noted that the best performance is the hood in the bath, built by yourself and working on the principle of natural circulation. It can be easily adjusted with simple dampers, does not require maintenance and the availability of electricity.However, greater comfort can be achieved by using simple electrical devices.

To guarantee the safety of vacationers, to eliminate the very possibility of electric shock, it is necessary to use devices designed for power supply of 12 or 36 volts. And then you can do it yourself do-it-yourself hood in the bath, which will provide maximum comfort and the best convenience of adjusting the temperature inside the steam room.
