How to make ventilation in the steam room with your own hands. Proper ventilation in the bath: the steam room does not need waste. Consider the schemes in the Russian bath and frame walls. Video - Arrangement of ventilation holes

The positive impact of regular bath procedures on the body is invaluable. At the same time, a bath is not just healthy, it is also a spiritual pastime, relaxation and gatherings. However, all the benefits will be easily blocked by the difficulties that will certainly appear if there is no effective ventilation in the bath.

Importance of the system

Even in the old days, architects understood that the lack of fresh air in the bathhouse can quickly cause dampness, mold, fungal spores, which inevitably leads to the destruction of the structure. That is why even in ancient times, builders left small gaps between the logs - they contributed to the improvement of air exchange and high-quality ventilation. Today, these primitive technologies have been replaced by modern, efficient systems that require effort, money and time for planning and installation.

Some homeowners skip this stage of work, but this is a very big mistake, because after a couple of years such buildings will simply become unusable due to constant high humidity, and if the bath is built using frame technology, then its service life will be even less. The first sign of the destruction that has begun will be a musty smell, which will be most noticeable at the moment the stove is kindled. This will negate any pleasure from the procedure. Being in such a steam room is not only unpleasant, but also quite dangerous for life and health, since carbon monoxide, fungal and mold spores accumulate in the air, which provoke the development of dangerous diseases of the bronchopulmonary system.

Effective ventilation in the bath must certainly comply with the basic requirements and principles of safety:

• Proper distribution of air masses. As is known from the school physics course, high-temperature air masses rush up, and cold ones, on the contrary, fall. Therefore, the flows should be directed so that the legs do not freeze, and the sunbeds have a comfortable temperature.
• Maintaining a predetermined level of heating in the steam room. Under no circumstances should ventilation interfere with the functionality of the steam room, that is, air cooling is unacceptable.
• The use of waterproof materials. For the arrangement of steam rooms and the organization of ventilation, it is necessary to use materials that are resistant to moisture and elevated temperatures.

The main difficulty in creating effective system air exchange is that it is faced with the task of quickly removing hot moist air from all parts of the bath, but at the same time it is required to prevent a decrease in temperature in the hot steam room, therefore modern systems, as a rule, use the installation of hoods that do not allow cold air to be blown in from the street. The presence of such systems is of fundamental importance for buildings equipped with solid fuel and gas furnaces, since such schemes require a large amount of oxygen to support the combustion process.

How it works?

High-quality ventilation in a steam room consists of ventilation and complete drying of all functional areas, as well as walls, floors, attic and the entire under-roofing area. Exhaust openings in the attic are made in the form of small windows, as well as aerators or spotlights - this largely depends on the type of roof and the materials for its manufacture. If the building is insulated, then a counter-lattice is additionally mounted, which allows ventilation to be achieved between the layer of thermal insulation material and other layers roofing cake. It is also installed to ventilate wall structures, which is very important to prevent the formation of condensate in the bath.

But for the best drying of the floors, a burst ventilation system is used or a ventilated floor is arranged. Such options should be considered at the planning stage of construction work. To do this, a subfloor is laid and concrete is poured at an angle, then the boards are laid in such a way that small gaps remain between them, through which excessive moisture is removed.

It should be noted that absolutely all bath rooms need airing: a steam room, a sink, a rest room, as well as other rooms. In order for ventilation to be most effective, it is necessary to select in advance such a scheme that will correspond to the characteristics of the bath and the conditions of its operation.

Experienced Builders they do not advise to carry out complex ventilation systems and recommend giving preference to the simplest and most familiar methods that may be suitable for each individual case. Here, the statement that the simpler the better is 100% true, and at its cost this option will be much cheaper.

The principle of operation of ventilation is based on the laws of physics. As a rule, 2 windows are cut out in such rooms: one of them is responsible for the supply of fresh street air, and the second allows overheated and humid air to come out. How these windows are located in relation to each other depends largely on which zone of the complex and with what intensity the air heated from the furnace will penetrate, since it moves under the influence of cold air masses coming from the street. This explains the fact that in some baths two outlets are cut instead of a single outlet, which makes it possible to redirect heat flows in the desired direction.

Of fundamental importance are the dimensions of the windows, as well as the possibility of full or partial regulation of the clearance. To do this, special valves are fixed on them, allowing you to cover any open slots.

It is very important to make the correct calculations of the window, taking into account the size of the room. If the windows are too large, then the steam room simply cannot warm up to the required temperature and you will have to spend large quantity electricity. And if the windows are too small, then the intensity of the movement of flows will be reduced and a complete supersaturation of the air with water vapor may occur.

The size and location of the ventilation windows primarily affects the ingress and uniform mixing of air, as well as its removal from the overheated room. As for the uneven distribution of temperatures in different parts of the steam room, this phenomenon cannot be completely avoided, but it is possible to ensure that the effect is invisible to visitors to the steam room and washing room and does not cause any discomfort.

Kinds

High-quality ventilation of bath rooms extends the life of the steam room up to 50 years and even more. The variant of the ventilation system in each case is selected individually and is largely determined by the location of the building and the materials that were used in its construction. All the options for arranging ventilation developed to date, according to the basic principle of operation, are divided into natural, forced, and also combined.

natural ventilation assumes that the change of air is carried out due to the unimpeded flow of flows from the outside, their mixing with the air layers of the steam rooms and the removal of the exhaust through special openings.

Forced the system is based on the use of fans. As a rule, they are installed on the hood and much less often on the inflow. Typically, fans are installed not only in the steam room, but also in the washing room, as well as in the rest room.

Combined variant, as the name implies, includes elements of natural and forced ventilation.

Among the popular schemes, “bastu” is the most common. It involves the formation of a small opening with an adjustable valve, which works for inflow and is usually located behind or below the furnace.

As additional elements, vents are equipped above the stove, which are controlled by a valve and a valve - it is through them that air enters from the outside through the vents from the underground. Usually the opening of such a box remains closed for some period, however, as soon as there is a need to reduce the level of humidity in the bath, both exhaust valves open. This scheme could be considered ideal if not for some of its limitations. Unfortunately, it is far from suitable in every case, therefore, in some situations, the installation of an exhaust system becomes a more preferable ventilation option - for this, a fan is attached to the bottom of the box. If you install it in the supply hole behind the stove, you can get a supply type of ventilation.

There is another scheme that is quite often used in steam rooms - with it, moist superheated air is removed from the steam room space through the upper and lower openings equipped with valves, and fresh air enters through vents in the floor under the firebox. From the outside of the building, such holes are interconnected by a special ventilation duct. Less often, an exhaust hood is installed in the baths, in which one single channel works for the entry of air jets and one for their removal, while both are equipped at the same height from the floor level: one is placed behind the stove, and the second is opposite on the opposite wall. This system requires mandatory installation of forced ventilation.

The most unfortunate way involves arranging both inflow and exhaust on one side opposite the firebox. In such a system, fresh air coming in from the street seeks its way to the stove and, during its movement, stumbles upon the feet of the steamers. This creates a draft, which significantly reduces the level of comfort from staying in the steam room. However, such an arrangement is also quite common when it is not technically possible to make holes with different sides premises.

materials

The choice of the bath ventilation system is largely influenced by the type of structure and the material from which it is made. If the bath is equipped in a separate building, then it is quite simple to plan and install the most preferred type ventilation. But if the bath has common wall with living rooms, then ventilation must be taken especially carefully in order to prevent waterlogging and rotting of the wall.

The ventilation system in the baths of the second type can only be forced, that is, it must necessarily include a fan, which will help to effectively dry the wall. The ventilation of the bath can be connected to the elements of general house ventilation or independently go outside. Ventilation ducts in frame buildings are equipped directly in the walls, and later they are brought out to the roof or even higher. For maximum air flow, functional air vents are installed in the foundation or a ventilation valve is installed.

The peculiarity of the buildings according to the frame method is that the walls in them are covered with a large number of heat-insulating layers, which completely excludes the possibility of arranging natural ventilation. That is why the best option here would be to create supply and exhaust system ventilation. In order for the air exchange to be of the highest quality, they use the creation of two channels: one is placed near the floor and supplemented with a fan, it is used for inflow, and the second serves to remove the exhaust air - it is mounted a little higher. The openings of such openings are closed with shutters.

In baths built from gas blocks and foam blocks, due to the individual characteristics of the material, galvanized air ducts are equipped. To do this, they purchase ready-made pipes, some even make them from simple sewer pipes. Some craftsmen create a ventilation duct on their own from galvanized leaves, after giving them the necessary configuration and reliably sealing the joints. As a rule, in such buildings, air ducts are laid over the side walls.

The easiest way to arrange ventilation is in a classic Russian log bath. Here it makes sense to equip a natural exhaust system. If the wood is breathable, gaps are formed between the logs from the floor to the bottom edge, and windows are provided in all the rooms of the bath, then additional ventilation structures will not be required. However, the problem often arises of creating optimal proportions between the air entering from outside and leaving the street. In order to prevent the occurrence of drafts and not to "heat the street", experts recommend additionally insulating the bath well and equipping small holes with special valves inside the thermal insulation material, which serve to enter and remove flows.

In buildings made of wood, the burst ventilation method is often used, in which all windows and doors are opened at the same time.

Brick buildings initially do not provide for the possibility of air exchange, so any natural exhaust is absolutely excluded here. Because of this, ventilation should be planned at the stage of drawing up a construction project. At the same time, it is important to accurately imagine how many bathers will take bath procedures. If the bath is being built for a small family, then you can simply arrange a small supply hole near the stove and an exhaust hole under the ceiling, and if the building is focused on a large company, then forced options should be preferred.

How to make your own?

In order to create in the steam room and other bath rooms comfortable conditions, it is necessary to properly equip the ventilation system. You can spend it in the bath both on your own and with the involvement of specialists. This will require a project of work, materials and tools, as well as a little time and effort.

What will be needed?

For the installation of ventilation ducts in the bath, preparation is needed. In the work you will need components:

• several ventilation valves;
• valve;
• metal grating;
• mosquito net;
• ventilation box;
• corrugated air duct;
• hygrometer;
• fan;

• thermometer;
• metallized adhesive tape;
• collar;
• mounting foam;
• sealant;
• fasteners;
• decorative overlays for facing inlet and outlet openings.

By the way, the latter are widely represented in any store in a variety of colors and textures, so getting the best option will not be a problem. Vent valves are installed on the exhaust and supply openings. They may differ in shape, as well as in size and material of manufacture. Gate valves are used to quickly open or close openings. They are made from the most various materials, and some home craftsmen even make them with their own hands, and in terms of strength and fixation strength, they are in no way inferior to store options.

A grid with a mesh, as in ordinary houses, is necessary in order to create a barrier to insects and rodents, whose presence is highly undesirable either at home or in a bathhouse. Most often they are made of metal, but there are options made of heat-resistant plastic.

The box, as a rule, is attached from the outer wall, but if there is no technical possibility for this, it is simply laid along the top. This arrangement is typical for buildings made of aerated concrete. Some make the box on their own, using corrugated pipes for this. Keep in mind that plastic options not suitable for steam rooms, because under the influence of high temperatures, most types of plastic begin to deform.

The fan in the steam room is used for both supply and exhaust air. It is optimal if in the room it will work only in the general direction. Such a device should be purchased in a heat-resistant version, which is specially made for Finnish saunas and baths. Thermo and hygrometers are used to make the use of the bath as practical as possible. For example, in systems with forced ventilation, temperature sensors are often installed that analyze the real state of the air and, depending on its performance, open the supply valve or start the exhaust.

Planning for the construction of the steam room

It is optimal if the entire ventilation system is thought out in advance - even at the design stage of the building. To choose the most suitable design, it is worth focusing on some of the nuances of installation work. The ventilation system, as a rule, is laid at the construction stage of the bath, it is at this time that all the necessary channels are laid and openings are formed into which they will later be walled up or to which they will be attached. Adjustable windows themselves are fixed only after work on decorative trim complex.

All ventilation openings usually have an identical size, while if the task is to increase the degree of air outflow, then the exhaust window is made slightly larger than the supply window, but in no case vice versa. The formation of an exhaust hole with a diameter lower than that of the supply one is strictly not allowed, because such a design can pose a threat to the life and health of users.

By all means, dampers and valves must be provided in the system, and the latter are considered the most preferable option, since they allow closing the holes with the greatest tightness without the formation of any gaps. Adjustable shutters are also important because the air flow depends not only on the size of the window, but also on the season. In winter, when negative temperatures prevail outside the window, cold air masses penetrate the bathhouse more intensively, which is why the windows are partially opened in the autumn-winter period, thereby delaying the entry of large volumes of frosty air masses.

As for the ventilation window, the size of its cross section is calculated based on the volume of the steam room. A standard has been conditionally adopted, according to which the window area must correspond to 24 cm2 for each cubic meter of space. If the calculations are made with violations and deviations in one direction or another, then the room will be too much ventilated, or vice versa.

Even at the design stage of the bath, it should be remembered that ventilation windows should not be located exactly opposite each other at the same level. In this case, warm air masses will not have normal circulation and will not be able to cover all the required areas of heating. Exhaust openings should be located slightly below ceiling level. This is due to the fact that warm air rises up. If the system has an outlet for superheated air flows, then they are effectively removed to the outside, and if the holes are low, then the exhaust air cannot find a place for removal and the general microclimate in the room becomes uncomfortable.

Separately, floor ventilation should be provided, since with constant contact with water, wooden surfaces lose their performance characteristics, That's why important requirements for a ventilated floor:

• to form the possibility of a flow in the foundation, it is necessary to build small vents;
• the floor should be laid in such a way that there are gaps up to one centimeter in size between the boards;
• the finishing floor must be laid without fail above the level of the blower, which contributes to the fact that the stove starts to work as an additional hood;
• after taking bath procedures, you should leave the front door completely open until the floor dries.

As for the dressing room, it is easiest to equip ventilation here, since there is no direct contact with water in such a room. As a rule, a combined or natural ventilation method is formed here, when cool air enters through the supply duct and is removed using the exhaust mechanism of the steam room, where it enters under the action of a fan.

In addition, the installation of ventilators is allowed here, which may require a connection to the network. electric current and exit to the street .. As for the washing room, forced ventilation is usually built here, and air exchange here occurs with the help of an electric motor.

We organize the hood in an already built bath

Even ancient architects, far from the laws of physics, invented a method of ventilation, which was based on the creation of natural draft. Depending on how the bath was heated - in black or white, it also depended on where the heated air was discharged. In the first case, the stove did not function during direct soaring, so open windows and doors were used for ventilation. The white scheme provides for the construction of a chimney. As already mentioned, the main elements of the air exchange system should be laid at the construction stage, however, there are options when it becomes necessary to equip the hood in an already built building.

To do this, you should punch holes right in the walls and supplement them with special plugs. One hole is punched in the area of ​​​​the furnace blowing, and the second - near the ceiling on the opposite side. Of course, this is easiest to do if the bath is built of logs. If the building is built of aerated concrete, and even more so of brick, then it will be much more problematic to form holes and equip the hood, since in the process of such work it is possible to violate the integrity of the walls at all in the wrong place, and the risk of destruction of the bath as a whole is quite high. That is why you should not independently do ventilation in already operated baths. Entrust these works to professionals who have the necessary skills and special tools. But if you are still determined to do all the work yourself, study the step-by-step guide.

In conclusion, it should be noted once again that the basic principles for creating an effective ventilation system largely depend on the dimensions of the bath and the materials from which they are made. However, in any case, there are a number of requirements that must be observed regardless of the specified parameters. Each steam room must have at least two openings. One is used for inflow, the second - for the removal of air masses. If you plan in advance the hood in the bath under construction, you can avoid serious problems with the installation of the ventilation system, which can cause air exchange problems in the steam room.

It is absolutely unacceptable that the installed ventilation creates the following problems:

A visit to the bath is not only a way to get rid of week-long dirt, but also to lose extra pounds or remove toxins from the body. However, a beneficial effect on the body can be felt only when correct device ventilation in the bath, which in most cases is far from ideal.

It would seem that in order to preserve heat and increase the rate of warming up the room, it is necessary to close up all the cracks, and lay a seal around the perimeter of the doorway so that the door closes tightly and does not serve as a source of cold air inflow. However, everything is exactly the opposite, since well-planned ventilation contributes to:

• creating a comfortable microclimate by getting rid of excessive heat, humidity levels, as well as reducing the concentration of carbon dioxide;
• rapid heating of the room due to the mixing of air masses, which is also accompanied by minimal cost fuel;
• protection of the interior finish, as well as the floor of the building, from the appearance of various kinds of mold, fungi, which contribute to the occurrence of an unpleasant odor;
• high-quality ventilation of all rooms of the bath, prolonging the service life.

Thus, ventilation in the bath plays a very important role both for the safety of the bath building over a long operational period, and for health benefits. At the same time, it will not be difficult to choose the required type of ventilation system, since you will have to choose from only 2 typical systems.

Types of ventilation systems, their characteristics

Before you learn how to make ventilation in the bath, you need to familiarize yourself with the main types and types of ventilation systems.

Based on the method of air inflow / outflow, there are 2 types of ventilation systems, each of which has undeniable advantages and disadvantages.

natural ventilation

Air exchange at natural system ventilation occurs under the influence of natural factors without the use of additional equipment in the form of fans, electric motors.

Among the natural factors of no small importance are:

• Wind pressure. The influx of fresh air into the bath is carried out under the influence of the force of the wind through the cracks in the walls, in the openings of doors or windows on the windward side. In this case, the flow of air is accompanied by the simultaneous displacement of rarefied air masses through the existing slots, which accumulate inside the bath at the top of the opposite wall.

An increase in wind pressure leads to an increase in the mass of rarefied air, thereby improving the ventilation of the bath room.

• Aeration. Cold air entering the heated bath through the slots at a small height from the floor or specially arranged holes gradually displaces hot air masses down, contributing to uniform heating of the room due to the mixing of air layers and the outflow of polluted air from the bath.

The benefits of natural ventilation in the bath are as follows:

• security associated with the lack of devices operating from the network;
• simplicity, since small gaps in the doorway or on the wall are an integral part of the wooden bath;
• low cost, as there is no need to purchase additional materials, as well as paying the costs of operating such a system.

Among the shortcomings it is worth highlighting:

• ventilation efficiency is entirely dependent on external natural factors;
• inability to adjust the degree of ventilation.

Therefore, natural ventilation in wooden bath it is quite enough for one family, since the tree itself is a breathable material, and cracks in the wooden structure during the drying process still take place. At the same time, for proper ventilation in brick bath it is better to dwell on an artificial system, since the formation of gaps when using such a building material is quite rare.

mechanical ventilation

Air exchange in the bath takes place regardless of the influence of external factors of nature using various kinds of fans, pumps and other equipment that promotes renewal and faster heating of the air.

Advantages of artificial ventilation:

• maintaining the microclimate in the bath at a given level;
• the possibility of filtering the incoming air;
• adjustment of the uniform distribution of heated air masses inside the room.

Flaws:

• higher cost relative to natural ventilation;
• the complexity of installation;
• noise during operation;
• energy costs for appliances.

The forced ventilation system in the bath, based on its inherent task, involves the use of such types of ventilation as:

1. Supply - provides access to the premises of the required volume of clean air. A typical mechanical ventilation system includes an air duct, an air intake grille, a filter, and an air valve. However, the greatest effect of the construction supply ventilation in the bath is achieved by installing an electric fan.

2. Exhaust - contributes to the removal of exhaust air from the bath room through a system consisting of an air duct, a grate, an electric motor, and a fan.

3. Supply and exhaust - a combination of the functions of the supply and exhaust systems. In this case, the distribution of air masses inside the bath occurs by:

• displacement of hot air outside the premises as a result of the gradual rise of air masses newly entering through the supply ventilation;

• mixing of hot and cold air due to the constant influx of fresh air.

Regardless of the type of ventilation, the cross section of the ventilation hole should be 24 cm per 1 m³.

Thus, forced ventilation is several times higher than the natural ventilation system. Based on this, the artificial ventilation system is the most optimal solution for arranging ventilation of a frame bath. At the same time, one should not forget that the supply and exhaust openings have a strictly ordered arrangement relative to each other, and not chaotic.

Vent placement options

The intensity of air exchange inside the bath room largely depends on the correct distribution of ventilation openings in relation to one another. Despite the many different variants alternative arrangement of openings for the inflow / outflow of air, the following bath ventilation schemes have become most popular:

1. The air flow is carried out behind the heater through an opening located at a distance of 30-40 cm from the floor level. In this case, the exhaust opening has a similar height, but is located on the opposite wall from the air inlet and is equipped with a fan. The cold air entering the room hits the wall of the heater and rushes up, gradually warming up in the process of lifting. At the same time, the exhaust air begins to move downwards and, under the action of the fan, is discharged outside. Such mixing of air masses leads to uniform heating of the air.
2. The principle of air movement in the bath is similar to the first option, with the only difference being that the height of the inlet is taken about 50 cm from the floor surface, and the exhaust is located at a distance of 10-20 cm from the floor line. In this way, even more intensive air exchange is achieved.
3. The supply opening is created at a distance of 30 cm from the finished floor in the wall opposite the stove. At the same time, the functions of the hood are performed by a chimney, along with a furnace blower. However, such a scheme is valid only during the operation of the furnace.
4. The distance from the floor to the air inlet located in the wall opposite the stove is taken 20-30 cm. At the same time, the hood equipped with a fan is located on the same wall at a distance of 20-30 cm from the ceiling. The air that has entered the room hits an obstacle in the form of a furnace and begins to rise, heating up and displacing the polluted air as it rises.
5. The air flow occurs at a distance of 20 cm from the floor in the wall behind the stove. The newly arrived air masses rise, gradually warming up, to the ceiling. As it cools, the air descends and leaves through the sex gaps, after which it enters the ventilation pipe, and from there outside the building.

Thus, the exhaust opening can be located below the supply opening only if there is a fan.

Several excellent ventilation schemes in the bath, the video of which is presented below, will help you make the final decision regarding your own design.

Bath ventilation device

Every year the design of the bath becomes more complicated, creating more comfortable conditions for those who like to take a steam bath or just wash in the bath. If earlier the bathhouse included a dressing room and a washing room combined with a steam room, today the bathhouse consists of 3-4 rooms:

• dressing room;

• washing;

• steam room;

• restroom.

Of course, the most important of these are the steam room and the washing room. However, the ventilation system must be arranged not only in these rooms, but also in the dressing room, as well as the rest room, since humidity also spreads to the rooms adjacent to the steam room.

steam room

For ventilation of the steam room of the bath, any of the above schemes is suitable. However, before firing the stove, it is necessary to completely ventilate the steam room by opening the door and all ventilation openings for 5-10 minutes. After the ventilation is completed, the door, as well as the exhaust openings, are closed. When the temperature in the steam room reaches the required limit, you can slowly open the exhaust outlet, adjusting the intensity of air exchange by means of a valve. In this case, the diameter of the exhaust hole cannot be less than the inlet, otherwise there will be reverse thrust, resulting in reduced airflow. However, it is necessary to ensure that the air flow does not violate the temperature regime inside the steam room.

washing

Along with the steam room, washing room baths are also associated with a large amount of moisture, the timeliness of getting rid of which is very important, since mold and dampness have a detrimental effect on both the human body and the duration of the operation of the building. Due to the fact that a large amount of water accumulates under the floor, an asbestos pipe placed in the corner of the sink can be used for ventilation in the washing bath. In this case, one end of the pipe should be between the finishing and subfloor, and the second is brought out to the roof and equipped with a deflector.

If the stove is located in the washing room, then the blower of the stove, located below the finishing floor, will also play the role of a good hood.

Foundation

When planning a building, you must immediately think about the ventilation of the foundation of the bath, since the laying of ventilation holes occurs at the stage of concrete reinforcement. To create holes for ventilation, asbestos pipes are quite suitable, which are strictly horizontally fixed in the intended places by means of wire and reinforcement rods, after which the pipes are covered with dry sand. At the same time, the distance from the ground level to the pipe should be at least 10-15 cm, so that when lifting ground water during the off-season, do not worry about the possibility of flooding. After fixing the pipes, the foundation is poured with concrete. In this case, the sand is removed only after the concrete has completely hardened. For normal ventilation of the foundation, 2-4 holes with a diameter of 10 cm are sufficient, located in opposite places to each other. To protect against insects, the openings are protected by installing mesh grilles on the ventilation openings.

dressing room

An integral part of any bath is the dressing room, where a mini-dressing room is arranged. In addition, a stove is often placed in the dressing room. In most cases, this is due to the small area of ​​the steam room or in order to prevent the accumulation of debris directly in the steam room. At the same time, the stove copes remarkably well with the functions of ventilation in the dressing room of the bath, because it is necessary to get rid of the condensate that appears as a result of opening the steam room door.

If there is no stove in the dressing room, then after the bath procedures, you can simply open the window or the door to the street and ventilate the room well.

An alternative ventilation option is to install an exhaust vent equipped with a fan at the top of the wall bordering the street.

Based on the specific situation, one of several options for ventilating the room is used. However, it is necessary to think through all the details of arranging the dressing room during the planning period.

Thus, it is not so difficult to build ventilation in the bath with your own hands. The main thing is to carefully approach the planning process and choose the right type of ventilation system, which largely depends on the structural features of the structure and the location of the bath.

The temperature regime of operation of bath rooms is very different from the microclimate of ordinary living rooms. Accordingly, more stringent requirements are put forward for air exchange inside the steam room. This guide discusses the traditional technique of how to properly ventilate a bathhouse built with your own hands from any materials - timber, logs or foam blocks.

Why do bathrooms need ventilation?

In the process of washing the air inside the sauna is heated and saturated with moisture. The higher the temperature in the steam room and washing room, the more water vapor the air can absorb. At the end of the bath procedures, the building cools down and the contained moisture begins to condensate on all wooden surfaces, provoking the formation of mold and fungus.

The supply and exhaust in the bath are designed to solve 3 tasks:

1. Renewal of the air environment during washing in accordance with the requirements of sanitary standards.
2. Removing excess moisture from the premises, drying wood.
3. Creating a circulation of moist air in the steam room.

The last point requires clarification. When you steam in a heated Russian banya and add a parka, hot humidified air rises to the ceiling. A properly installed hood removes cooling air masses, due to which circular flows arise that equalize the temperature throughout the entire height of the room. Without ventilation, the lower zone of the steam room will remain cold.

Reference. The physical processes occurring in the Russian and Finnish baths are almost the same. The difference lies in the temperature and degree of air humidity. In the first case, the temperature reaches 70-80 degrees, humidity - up to 70%, in the second - 100 ° C and 30%, respectively (the so-called dry steam).

In the washing room, rest room and dressing room, ordinary ventilation is needed to renew the air environment. For gas operation, an additional inflow is provided to ensure combustion.

Universal air exchange scheme

The most economical and efficient is considered classic version- natural ventilation in the steam room, shown in the diagram. The main washing system operates as follows:

1. The inflow is organized through a gap of 2-3 cm under the front door, where heated air from the adjacent room penetrates.
2. Receiving a dose of heat from the stove and saturated with steam, the hot air mass rises to the ceiling.
3. Cooling from contact with surfaces and people, the air descends to the lower zone, from where it is removed by means of an exhaust grille and a separate channel arranged in the opposite corner.
4. The volume of inflow is regulated by a valve installed on the exhaust port.

An important nuance. Hot moist air is much lighter than cold dry air, so the hood is provided from the bottom of the steam room. If you make a ventilation hole near the ceiling, the lion's share of the heat will go outside, it will be uncomfortable in the microclimate near the shelves.

How the bath ventilation system should work, the expert will tell in his video:

An auxiliary hood, made near the ceiling, is designed to ventilate and dry the steam room at the end of bath procedures. During washing, the hole is tightly closed with a valve. Instead of an exhaust opening, it is allowed to use ceiling diffusers or a regular swing-out window.

Consider several alternative steam room ventilation schemes shown below in the picture:

1. Supply of inflow directly from the street through a hole made near the stove. From contact with a hot surface, the air instantly warms up, circulates through the steam room and leaves through a vertical box to the outside.
2. A similar scheme with heating the inflow at the furnace, the exhaust is organized through a hidden channel under a wooden deck. In a steam room with a concrete floor, such a solution is difficult to implement.
3. Role exhaust duct the stove chimney plays, in which a priori there is good draft.

Note. These schemes are used in certain conditions- when air is supplied from the street, exhaust through the floors or in the case of placing the firebox inside the steam room.

In other rooms, the ventilation device is simpler - the hood is provided in the upper zone, the inflow is supplied to the lower one. Moreover, in winter, fresh air must be heated or first passed through a dressing room so that it does not blow cold in the steam room. To clean and heat the street flow, it is advisable to use local supply units with forced air injection.

Choosing the Right Materials

The very idea of ​​a Russian or Finnish bath involves the use of environmentally friendly materials and the corresponding heating equipment. If you are, the use of polymer insulation, glass wool and various plastic elements is not allowed.

To arrange ventilation in the bath (especially in the steam room) with your own hands, it is recommended to purchase the following materials:

• air ducts made of galvanized steel or wooden boxes;
• grilles, shutters and diffusers - made of wood or painted metal;
• sealing pipes with access to the wall - tow, moss, jute;
• fans - made of special plastic, with a high degree of electrical protection against moisture.

Advice. Try to use a minimum in the steam room metal elements. If you raise the temperature to 80-100 ° C, the parts will get very hot and can burn you if accidentally touched.

Inside the steam room, it is categorically not recommended to make ventilation from a plastic pipe. When heated to 100 degrees, the polymer begins to lose stability and releases harmful substances. In a good way, you can’t put fans in the steam room either, and there’s no need to.

Forced exhaust creates a powerful air flow, entraining a large amount of heat, the oven will run idle. For drying the bath, the fan is also not a panacea - just open the window and the front door, organizing a draft. Injection is appropriate in one case - when it works Supply unit with heating.

Ideally, ventilation is designed and laid down at the construction stage of the bath. The placement of air ducts is thought out in advance, the furnace model and the air exchange scheme are selected. The best option the main hood - through the floors into the side vertical channel, more economical - grill or diffuser in the wall.

An important point. Often there is a mistake when the owner competently equips the hood, forgets about the inflow and gets a deplorable result - mold in the corners. Remember: without fresh air replacement exhaust ventilation will not work. Installing a suction fan will not solve the problem either.

When installing ventilation, we suggest following simple recommendations:

If a bath with a steam room has already been built, the ventilation duct can be brought out through the wall and raised to a height of 3-4 m next to the chimney. It is desirable to insulate the pipe, otherwise you will have to deal with condensation. How best to organize the ventilation of bath rooms, look at the video:

Do-it-yourself ventilation in the bath? - easily, the event can be carried out by a man without professional skills. Why do you even need to monitor how to properly ventilate the bath? The answer is obvious. Right arranged ventilation in the bath affects the maintenance of temperature in the locker room, washing room, steam room, or relaxation room. The second, but no less significant impact, the movement of air masses has on safety wooden structureand the service life of its parts.

When designing a bath complex and its construction, it must be taken into account that the ventilation of the bath complex should be carried out taking into account established rules complemented by subtle nuances. Information on how to make ventilation in the bath with your own hands, with detailed instructions, photos and videos abound. We will outline the main stages of installing air exchange inside the bath space and the steam room below.

Properly arranged ventilation in the bath is guaranteed to keep the temperature at a comfortable level inside the steam room. Extending the life of wooden structures.

The operation of the ventilation system based on the known laws of physics, as well as the ventilation scheme, is understandable and does not raise questions. To fulfill the condition of air circulation in a constant mode, we need only a pair of holes of two types:

• exhaust;
• supply.

The intake of fresh air into the room will provide an inlet. The best place the location of the supply ventilation in the bath - near the stove, at a height as close as possible to the floor. Such an arrangement will provide rapid heating of the incoming air, not allowing it to cool the room, maintaining a constant temperature.

Scheme of air movement inside the steam room.

Extraction slots are necessary to remove superheated moist air and carbon monoxide (carbon monoxide) from the steam room. Exhaust openings should be located opposite, as high as possible, slightly below the edge of the ceiling. It is desirable to place both eyes opposite each other, for effective creation and maintaining a continuous exchange of air.

Attention! Do not plan the location of the exhaust outlet directly in the ceiling! A hole for the exit of air masses in the ceiling part leads to a sharp cooling of the bath, preventing hot masses from lingering.

With the concept of locating the supply and exhaust openings, everything is clear and there are no problems in organizing work on the ventilation device in the bathhouse with your own hands. But the task of maintaining a high temperature in the steam room and at the same time effective removal exhaust air and carbon monoxide remains open.

You should also pay attention that the ventilation in the bath should work to maintain an acceptable temperature in the rooms for hygiene procedures, in the dressing room, and other parts of the room: in the dressing room, in the washing room and in the rest room. And if you are faced with the task of implementing a ventilation scheme in a steam room with your own hands, you should think about correct execution work.

The correct scheme of air circulation in the bath

Main types of ventilation

There are two main types of ventilation:

• natural;
• forced.

Which one to choose depends on the design of the bath and the volume of its premises.

Ventilation using an electronic control unit

Natural ventilation of the bath

It starts up on its own due to the difference in temperature and pressure inside the room and outside. The efficiency of natural flows depends on the placement of air inlet and outlet openings. It is better and more optimal when the feed holes are close to the floor. Place them at a height of 200-350 mm, next to the stove. It is better to place the exhaust pipes of the hood on the opposite wall, below the ceiling level of 150-200 mm.

Ventilation systems with natural air movement are not suitable for ventilating a steam room or sauna, as the cold air in this room accumulates at the bottom of the floor, and the hot air at the top. We also need hot streams to linger in the steam room as long as possible.

Adjusting the movement of the air flow is accompanied by difficulties, but with correct location do-it-yourself ventilation system components, you can deal with this problem.

Natural ventilation for a steam room is not desirable, it is advisable to organize it in a recreation area

Forced ventilation

This kind of air recirculation in a steam room of a Russian bath or a Finnish sauna can be divided into two subspecies:

• The ventilation controls the temperature and humidity through the automation of the electronic system, by automatically adjusting the supply and filtration. Such systems are expensive, and their use often does not match the allocated budget.
• Combined ventilation system sharing normal natural air exchange combined with a forced fan.

Scheme of internal ventilation ducts in the wall of the bath

Ventilation in the bath depends on the type of construction

The natural movement of air with the correct location of the ventilation holes and their sizes corresponding to the volume of the premises works well in a Russian bath, assembled from round logs or timber.

The structure of the frame of the steam room must be airtight. Appropriate in frame baths from a bar, use forced ventilation. Air vents for filing suit in outer wall steam room and must be additionally equipped with a blower fan. In bath structures made of brick or concrete blocks, it is possible to achieve high-quality air movement only through forced ventilation.

Depending on what material the bath is built from, the ventilation system is selected.

We plan ventilation in the bath: subtleties and nuances

Before proceeding to the choice of ventilation scheme in the bath and the device of its design with your own hands, you need to understand the subtleties and nuances of the design.

Carefully! Even a slight mistake in the location of the air inlet and outlet leads to backfire. In the steam room or go down the right hot temperature or increase the concentration of carbon monoxide (carbon monoxide).

The ventilation system is laid down at the design stage of structures - the necessary channels are planned and the location of the inlet and outlet windows is determined. During the construction of the bath, adjustable windows are installed after the decorative sheathing of the room. The organization of the exchange of air masses in the room and the question "How to make ventilation in the bath" must be resolved at the design stage.

The ventilation ducts of the dressing room, bathroom, steam room, rest room, as well as openings for the inflow of fresh air and the removal of a mixture of carbon monoxide, including moist air masses, must be installed at the appropriate stages of construction. On the stage final finishing rooms, valves and gratings are installed to control the size of the supply and exhaust openings and the cross sections of the ventilation ducts.

Basically, two factors affect the effective functioning of the ventilation of the bath:

• ventilation window size. Both supply and exhaust air openings are determined by the amount of space, whether it is a dressing room, a washing room, a steam room or a relaxation room;
• location of slots relative to each other.

1. Vent size

The dimensions of the slots depend on the number and volume of rooms: dressing room, steam room, bath room or lounge. It is necessary to choose the optimal size of these holes, as well as to provide the possibility of its regulation. To adjust the gaps in the holes, install the door damper and the grille. The exhaust opening is made with approximately the same dimensions as the dimensions of the supply opening. In any case, the "hood" should not be less than the "supply", otherwise it is impossible to ensure a full outflow of moist and carbon monoxide air from the steam room.

In the photo on the left. air vent with slider to regulate the amount of fresh air. Keep in mind that with a large number of ventilation windows, it is more difficult to heat the sauna room to the correct temperature.

Large ventilation windows lead to excessive consumption of fuel or electricity. In addition, there are problems with adjusting the cross section of the ventilation ducts. It is difficult to relax if you constantly have to change the position of each valve.

IMPORTANT! The dimensions of the ventilation hole are calculated as 24 cm2 per 1 m3 of the volume of the ventilated area. For a good supply of fresh air from outside, the outlet eye must be larger than the inlet.

If the area of ​​the ventilation holes is insufficient, the temperature, humidity and concentration of carbon monoxide in the room can rise to critical levels.

The required dimension of the ventilation opening is designed at the rate of 24 sq.cm per 1 cubic meter bath volume

2. The location of the ventilation holes relative to each other

The functioning of any ventilation system is based on the replacement of a mass of hot air with cold air. The movement occurs under the pressure of cold air from outside, as it is heavier. It remains only to provide for the possibility of adjusting the direction of the flow of hot air coming from the stove installed in the bath.

For this reason, ventilation in a steam room is not limited to equipping a single supply hole. It is necessary to plan two windows. To optimize the heat flow, it is enough to adjust the gaps of a certain width in the holes with the help of a valve - a valve.

Ventilation in the Russian bath

Collect ventilation in the bath with my own hands easier if you follow a simple rule. Qualitative indicators of the ventilation system in the bath are laid at the initial stage design work. In the bath, the circulating air flows in the rooms have a pronounced temperature difference, to level discomfort from this mixture is the main task.

IMPORTANT! A comfortable atmosphere in the bath depends not only on the absence of sudden changes in temperature "horizontally", that is, when moving from one room to another: from the relaxation room to the locker room or from the steam room to the washing room. Synchronous mixing of air masses in the vertical plane is necessary: ​​the air temperature near the floor should not be significantly lower than the temperature at the level of human growth.

The microclimate in the bath is directly affected by the number, size and location of ventilation windows.

The uniformity of intake, mixing and removal of air masses depends on the number of supply and exhaust openings, their size and location relative to each other, as well as heating devices and equipment of additional devices.

Block diagram of the ventilation device in the bath

Any scheme of the ventilation system in the bath is designed with one goal in mind - maintaining the temperature, humidity and freshness of the air in the steam room. Bath rooms, especially steam rooms, are exposed to water and steam, so periodic ventilation and drying is required. But airing and drying will be ineffective if proper ventilation is not organized in the bath. Proper and continuous ventilation of the steam room greatly reduces the effects of wood absorption of moisture.

Ventilation in the bath controls the temperature, humidity and freshness of the air in the steam room.

Do-it-yourself floor ventilation in the bath

Air exchange in baths and saunas, among other things, provides a ventilated floor.
in constant contact with water, they lose their appearance and become unusable after 4 years. Requirements for ventilation organized by means of the floor:

• it is necessary to create a stream, and make a small vent in the foundation part of the building;
• the floor should be laid, leaving a gap between the boards of 1 cm;
• position the air inlets in parallel walls(not forgetting to protect the adjustment grids from rodents);
• it is desirable to make the stove work as an additional hood, for this it is necessary to plan the level of the finished floor above the blower;
• required after completion water procedures, leave the door to the steam room open until the floor in the room is dry.

Ventilation in the bath - a general scheme of the system

Ventilation in the dressing room of the bath

There is no direct contact with water in the dressing room. That is why it is not difficult to make ventilation with your own hands in the wardrobe room, armed with photos and videos with instructions.

Use natural or hybrid ventilation. Use a fan to supply fresh air. Install vents with ventilators that need direct access to the street and a power cable connection to the power supply.

Natural and combined ventilation is allowed in the dressing room.

Ventilation in the washing area

To optimize the air exchange in the washing room, a forced ventilation system is used. It is driven by an electric motor. The air flow is removed in the direction of the vestibule (vestibule). The air supply and exhaust ducts are mounted with the same cross section. section. The inlet opening is located above ground level (2 m) and the outlet of the outlet pipe is led out to the roof.

Steam room ventilation

Special requirements are imposed on the microclimate of the steam room. The steam room must be heated quickly, while maintaining the optimum level of humidity and without drafts. Thus, for a steam room, the actual position and dimensions of the inlet and outlet channels that are used in the construction of the bath are very important.

To regulate the inflow and outflow of air, there are enough valves in the ventilated openings. A large amount of space will most likely require the use of a blower or exhaust fan.

Scheme: ventilation in the steam room

We have given typical schematic diagrams for designing ventilation in a bathhouse. Video and images, attached instructions, will definitely help those who want to build a bath complex on their own. We wish you the speedy realization of your dreams in concrete forms!

Can be done by different schemes, but there is no doubt that this structure cannot be dispensed with without it.

The presence of ventilation in the bath depends not only on the correct distribution of heat in the room, but also on the safety of visitors, as well as longevity services of a wooden bath building. In a bath, especially in a steam room, there is always a large amount of water and steam, and wooden surfaces absorb moisture, and periodic drying of the room is simply necessary. However, it will not be effective enough if constant ventilation is not organized in the premises, which significantly reduces the effect of moisture absorption by wood, since the air is in continuous movement.

The principle of operation of ventilation in the bath

The operation of the ventilation system is based on the known laws of physics, and the principle of its arrangement is quite simple and understandable.

• In the bathhouse, two ventilation windows are arranged, one of which provides fresh air, and the second allows hot and waterlogged air to exit.
• From the exact location of the ventilation windows will depend on which area of ​​the room the heated air will flow more intensively, which moves under the pressure of the heavier cold air coming from outside. Therefore, sometimes two outlets are arranged instead of one - this is done in order to be able to direct the flow in the right direction by opening one of them or both at the same time by a certain amount.

Thus, a very important factor is the size of the windows, as well as the ability to adjust the clearance they open. To do this, they install gate valves, which can be completely covered or left open a small gap.

• Another important task is correct calculation the total size of the ventilation window, taking into account the area of ​​​​a particular room.

- If you install too large openings, the steam room will either never be able to heat up to the desired temperature, or this will lead to excessive consumption of fuel or energy, or in order to achieve the required temperature, it will take a long time to adjust the distance to which you need to open each of the ventilation windows.

- When not enough large sizes ventilation windows, the intensity of air movement will be noticeably reduced, which means that the room may overheat or oversaturate the air with moisture.

So, from the size of the ventilation openings, their location and the equipment of the system additional elements adjustments will depend on soft intake, uniform mixing and removal of air from the room. That is, it is necessary to provide for all these parameters so that there are no sharp thermal drops in the room for individual parts of the body of a person washing in the bath, for example, when cold air blows from the street down the legs, and at the same time the head is under the influence of very high temperatures.

In any case, there will be a difference in air flow temperatures, and this is normal, but visitors should not feel any discomfort from this. Therefore, the air should be mixed as evenly as possible - this depends on correct scheme ventilation system.

Important nuances of planning the ventilation system in the bath

Before proceeding with the choice of a ventilation system and the most suitable design, you need to understand some of the nuances that apply when installing any of them:

• The ventilation system is laid in the process - the necessary channels are laid and openings are made into which they are embedded or connected. Directly adjustable windows themselves are installed after the decorative sheathing of the room.

For that, to to carry out these works without problems, it is necessary to include ventilation in the bath project in order to carry out all further construction work based on it.

• Ventilation openings, ideally, should be the same size. If it is necessary to accelerate the outflow of exhaust air, then the exhaust hole is made a little larger than the inlet, but for safety reasons, in any case, it is forbidden to make it smaller than the latter. Sometimes, as mentioned above, instead of one, two exhaust windows are arranged, not only to adjust the distribution of flows, but also to ensure safety.
• Ventilation windows must necessarily have doors or shutters. It is preferable to install the latter, as they close more tightly, leaving no gaps.

• During the initial heating of the steam room, the gate valves are completely closed until the required temperature is reached.
• Adjustable dampers are also necessary because the flow of cold air depends on the season. So, at a negative winter temperature, cold enters a warm room more intensively. Therefore, during this period, the ventilation windows do not open completely, holding back the flow of cold.
• The cross-sectional area of ​​​​the ventilation window is calculated based on the volume of the bath room. There is a norm that for its one cubic meter a window area of ​​​​24 square meters is required. cm.

• With incorrect calculations, with deviations in one direction or the other, the room will not be sufficiently ventilated or vice versa, it will be too cold.
• Ventilation windows are never located opposite each other and at the same level, since hot air will not have normal circulation and will not cover all the necessary heating areas. Its uniform mixing will not occur, so you need to carefully calculate the correct placement of the ventilation elements.
• The windows for the hood are always located at a height slightly below the ceiling, because the superheated air mass rises up. If an exit is provided for it, it rushes into the exhaust opening, which contributes to the timely cleaning of the air in the room. Only under these conditions will the bath house be beneficial, and a favorable and healing atmosphere can be created in it.

Types of ventilation

IN different occasions, depending on the design of the building and the total volume of the bath room, one of the types of ventilation is arranged.

natural ventilation

This type of ventilation system is based on the difference in temperature and pressure in the street and indoors. The effectiveness of such ventilation is achieved by the correct placement of the inlet and outlet windows. So, the entrance for external air is located next to, at a height of 250 ÷ 350 mm from the floor, and exhaust windows are usually on the opposite wall of the room, 150 ÷ ​​250 mm below the ceiling.

It is believed that this option is not particularly suitable for a steam room, since the hottest place in this room is its upper area, and the coldest is the floor. Setting up natural ventilation in such conditions is quite difficult, but if you place its elements correctly, then even with this distribution of air flows, you can achieve the desired effect.

Forced ventilation

There are special electronic systems for saunas and steam Russian baths, which are trusted to control the temperature and air flow.

Displayed on the control panel desired temperature and the level of humidity that must be maintained in the room, creating a comfortable atmosphere in the bath. Such systems are carried out and connected by specialists, and such services are quite expensive.

Another option for forced ventilation is simpler in design and more affordable. This method of bath ventilation can be called the most widespread, as it will create the right atmosphere, regardless of weather conditions"overboard".

In this system, in addition to properly located ventilation windows, a device such as an exhaust fan will be needed. The combined version is especially good for baths located inside the house, where ventilation windows are not built into the outer wall, but a long ventilation duct is laid to them from it. In this case, the fan provides the required amount of air inflow and outflow.

The duct exhaust fan must comply with the special conditions of the "bath" operation

It should be noted that special fans are purchased for the bath, which have reinforced waterproofing of the elements of the electrical circuit and the mechanical part. In addition, such devices must withstand high temperatures without losing performance. The working diameter and power of the device are selected depending on the volume of the room.

The required type of ventilation is selected individually for different rooms and types of baths, so when choosing a scheme, you need to carefully think through and calculate everything. Very often it makes sense to provide a combined scheme that combines both the natural circulation of air flows and the possibility, if necessary, to resort to forced circulation.

Video: basic principles and schemes of bath ventilation

Common bath ventilation schemes

The presented diagrams show different options for the relative position of the heater and shelves in the steam room, and the distribution of supply, hot and mixed air flows advising them.

First scheme ( A)

The most used ventilation scheme in the bath is when the window for incoming air is located next to the stove, at a height of 250 ÷ 350 mm from the floor.

During the heating of the stove, cold heavy air coming from the ventilation window moves a light hot stream to the opposite wall, lifting it up to the exhaust opening, which is located at a distance of 150 ÷ ​​250 cm from the ceiling.

Going all the way, from the lower window to the upper, hot and mixed flows cover the entire room, warming the area of ​​​​the upper shelf located under the exhaust window as much as possible. If there is insufficient air movement, a fan is installed in the upper vent.

A regulator in the form of movable shutters can be built into the inlet, which will help both regulate the intensity of the intake of fresh air and, to a certain extent, set the direction of the flow in the right direction.

The second scheme ( b)

Natural intensive blowing is carried out through the lower window, arranged on the opposite wall from the furnace. The movement of air in this case is directed towards the heating device, where the hot flow emanating from it is picked up, rises and rushes to the exhaust hole along a wide arc covering the entire volume of the room.

This scheme is well suited for placing a bath, arranged in a house, and having one external wall. In order not to stretch the ventilation duct to the opposite side of the bath, both windows are installed in the wall facing the street.

The third scheme ( V)

This scheme is suitable for a bath with a leak. The air intake window is located exactly in the same place as in the first scheme, near the stove-heater. The output is organized a little differently.

The air, after warming up the upper area of ​​the steam room, goes down, passes through the slots of the flooring, thereby helping to evaporate the moisture that has collected there, which significantly extends the life of the wooden floor.

The exhaust vent is located in an adjacent room or in an isolated channel that no longer has access to the steam room. It is usually equipped with a fan to ensure stable air circulation along such a complex trajectory.

The scheme cannot be called very popular - it is used infrequently because of its complexity in accurate calculations of the location of the ventilation windows, a rather laborious device with the movement of air flows in its cavity. However, it should be borne in mind that it is very effective, and contributes to the most uniform heating of the steam room and, at the same time, helps to quickly evaporate moisture from the wooden floor structures and dry them out.

The fourth scheme ( G)

The fourth option is designed for a constantly working furnace - only in this case, its blower hole will act as an exhaust hood. The inlet window is located under the shelf installed on the opposite wall from the furnace, at the level of its blower.

Cold air is directed towards the furnace and raises the air heated by it to the ceiling. Cooling down, the air masses are forced down and go into the blower hole.

There are also more complex schemes in which there are two supply and two exhaust ventilation windows with forced air circulation. Such a scheme requires careful adjustment, but allows you to set the required temperature in the room as accurately as possible.

As stated above, ideal option the installation of the ventilation system will be carried out simultaneously with the construction of the bath. In the event that an already finished room is being converted into a bath, or its arrangement is being made, it is best to choose a room or separate a corner that has two external walls. In this case, there will be no problems with the device of the ventilation system.

If this is not possible and the bath is located in the middle of a private house, then there are two options to arrange ventilation of the room - to install a ventilation duct that will connect the room to the street, or to bring the ventilation pipe through the ceiling and roof. In this case, the pipe must be closed from above. protective umbrella, to prevent precipitation and fallen leaves from entering the ventilation ducts.
