Specificity of ventilation systems for baths

Bath needs regular air update. This is a safety requirement for people taking bath procedures. Also proper ventilation helps to extend the service life of up to 50 years or more.

ventilation system type is chosen individually and depends on the location, size, facilities, and materials used in the construction.

Scheme venting bath

All existing ventilation system on the principle of action are divided on natural, forced and combined. In the first case the ventilation is due to the arbitrary outdoor air admission, his room and stirring displacement exhaust through holes in a natural way.

Organization of the ventilation system in the bath is required not only to visitors, but also to the construction, especially if it is built of timber or logs

Supply of oxygen to the furnace operation

Bath stoves, wood-burning units especially, need a supply of oxygen to support combustion process

Dried accessories and finishing

To extend the service life of structures and objects of bath conditions need regular drying, which involves ventilation and airing

Supply valve next to the window

Normal conditions for the people, environment, structures and equipment in the bath ventilation through windows and doors is not enough. They only help better and faster to dry

Flue natural ventilation

By way of motivation air mass to motion of the ventilation system are divided into natural, mechanical and combined. In baths with natural ventilation air smokers change occurs on the basis of the laws of gravity

The mechanical version of the system

For venting large bath complexes, including several function rooms and recreation rooms, require a mechanical system. It moves the air due to the fan

Exhaust fan on a wooden wall

At the place of installation of the fan mechanical systems are divided into supply and exhaust. Charge air fans are installed on the inflow, the outlet air - on the hood

Supply opening combined system

In embodiments, combined: if the fan blows air, it is discharged through the exhaust port naturally if the fan draws air, its volume is renewed by natural inflow

In the second operation included in the additional device - fan. Most often it is put on the hood, but you can on the inflow. The fan is used in each of the baths Improvement. In a third - a symbiosis of the first and second embodiments.

Ventilator bath

When choosing a fan for drawing, it is necessary to pay attention to its degree of protection (IP44 above) and the body, which must be heat resistant

Additional ventilation schemes used in baths, most popular strikers. It involves opening device for controlled inflow valve, which is located behind / underneath the oven. Additionally, under the oven vents may be controlled by a valve or gate valve. Air flows therethrough from the underground penetrating from outside through the air holes in the foundation.

Low noise fan for bath

Additional fans for saunas can be found practically noiseless model. They are powerful, creating noise at work in the 22-35 dB

The upper opening of the duct is closed to the desired time. As soon as there is a need to dry the room, opened just 2 exhaust valve.

This seems to be the ideal scheme is not always appropriate. Then apply a forced ventilation option. If you add an exhaust fan in the lower part of the inlet ventilation duct in this scheme, we get exhaust system. When the fan is mounted in the supply opening of / above the oven obtain inflow circuit venting steam.

Scheme ventilation in the bath

Cold air entering the steam room, immediately warming. And the exhaust is forced into the lower opening of the ventilation ducts, arranged on the opposite wall

One more ventilation systemUsed in the baths, when the inflow occurs through vents located at the bottom of the room, near the floor, and removing - through the top hole arranged with installed ventilation valves.

Outside these openings are connected to a common air ducts rising to a certain height. The height of the lower exhaust valve - of about 50-60 cm from the floor, and upper - 30-40 from the ceiling.

Holes with valves

Basta is convenient to use scheme with openings special adjustable dampers. After opening and closing can be as required by setting the appropriate gap size / hole

Ventilation scheme in which one channel is enabled for the inflow and one for the removal of air masses, also used in the baths. Moreover, these two openings are located at the same height from the floor. The first of the furnace, and the second - on the opposite wall. There sure to install an exhaust fan to the ventilation system to work.

Kit for ventilating device

All components used for the ventilation device, you need to select the appropriate level of moisture and heat resistance, specifically designed for baths and saunas

The worst option, when supply and exhaust are arranged on one wall, just in front of the furnace. Unfortunately, this pattern is also not uncommon for other circuits can not possibly be applied in specific circumstances.

With this arrangement the fresh air entering the room, searching for a path to the furnace, passing over the floating leg bumping. Then, once in the right place and warmed up, it rises upwards, it is mixed with steam and leaving at the hole located at 20-30 cm from the ceiling. He does not have time fully to work was full of the desired extent with carbon dioxide.

Ventilation holes in the bath

Unfortunate location of the ventilation holes in the bath is fraught with drafts and insufficient oxygenation premises

Structural components of the system

In the bath ventilation is necessary for the safety of people and to ensure acceptable conditions of operation of the premises materials. Development and device ventilation system does not mean that have to spend huge money on the implementation of useless projects.

High-quality ventilation baths

Quality bath ventilation is not tantamount to an expensive ventilation. Everything will depend on the specific conditions of individual buildings

High-quality ventilation implemented in the bath includes ventilation and drying:

  • all rooms;
  • constructs the walls;
  • floor drying;
  • ventilation of the attic and roof space.

As the air vents in the attic made special windows, soffits or put aerators - it all depends on the type of roof and materials. Roofing dry cake is obtained by the device ventilation of roof space.

If there is insulation, then put kontrobreshetku necessary to provide ventilation between the insulation and other layers of the roof. It is used for venting constructs walls, so that the thickness of the layers prevents condensation.

For floors used volley drying or airing equip ventilated floor. This embodiment should provide for the construction phase. To do this, perform the subfloor thoroughly Bay sloped concrete and finishing plank of hardwood planks, leaving a small gap between them. Such a floor enables rapid removal of excess moisture.

Ventilation in all rooms bath

It is important to arrange the ventilation in all rooms baths. Particular attention should be paid to the wash / shower room where humidity threatens the formation of mold and mildew

The ventilation need all bath areas, including:
  • steam room;
  • pomyvochnaya;
  • dressing room / lounge;
  • other rooms.

To arrange proper ventilation, it is necessary to select the optimum scheme suitable to the requirements and conditions of the particular bath. It is important to remember that fresh air should flow to all rooms and is also removed from all.

Installation ventkanala bath

Construct air ducts, doing a supply and exhaust openings in walls or mount an entire duct system - all very individual

Seasoned Wizard is not recommended to lay complicated air ducts system, preferring to focus on the simplest solution suitable for a particular application. It employs a rule - the simpler the better. And for the price easiest option would cost several times cheaper.

Owning a Finnish sauna and bath complexes with two or more kinds of paired, including oriental hammam, be sure to check with the specific in the sauna ventilation deviceDescribed in detail in the proposed article.

The dependence of material bath Ventilation walls

Ventilation system for a bath just depends on the room type and the material from which it was built. This can be a separate structure or several rooms in the long-built house. The first option is preferable - it is convenient to plan and arrange ventilation systems, choosing the most inexpensive way.

If the bath is adjacent to the living quarters, you should pay special attention to its drying to protect the walls from rotting house. Also, do not forget that the temperature in the steam room will be high, so the surrounding walls is necessary to make an additional heat-resistant.

Sauna in part of a residential house

Most often, in terms of residential building is not satisfied with the usual Russian bath and sauna, where less steam and more heat

In this case, the ventilation system will only be compulsory. It must necessarily take into account the safety of the walls and supporting structures of a house. Ventilation system such baths will be part of the system of the house. Air ducts may also be coupled with or separately obschedomovyh enter the roof or the wall of the street.

Depending on the type of material bath are:

  • of bricks;
  • logs;
  • of gazoblokov;
  • timber;
  • wooden frame with insulation.

In the brick and frame baths can arrange air ducts in the walls, taking them to the roof or above. For paving inflow duct, vent valve or using the air holes in the foundation. Be sure to put an exhaust fan for a better removal of the exhaust air.

ground deflector

If the bath is located in the basement, the ground mounted deflector for optimal traction

Baths of gazoblokov due to the characteristics of the material of the walls equipped with galvanized ducts buying ready-made pipe. Sometimes arrange ventkanal of galvanized sheets, giving them the appropriate form and to seal all joints. Ducts must pass over the wall.

If the material used in the logs, the possibility of natural ventilation is due to the peculiarities of wood and construction technology. When the tree breathes, has the necessary gaps between the logs are provided windows in all the rooms baths, arranged clearance from the floor to the lower edge of the door by 2-3 cm, construction of additional ventilation channels can not would need.

Old room with natural ventilation

Still alive vivid examples baths, built 50 or more years ago. They occasionally have become even stronger, and bathe in them - it is a pleasure

But to achieve the optimal balance between incoming and outgoing air, steam can be very difficult. To avoid drafts and not to heat the entire street, often prefer to further insulate wooden bath by arranging within the bore in valve to remove / air intake.

Features ventilation device

Greater role in the selection of optimal ventilation scheme plays a bath material, its location, detached or not. All this helps to make the right decision when vensistemy device.

One of the most effective methods of ventilation a volley ventilation - when you need to quickly ventilate all, open all doors and windows. Of course, this can be realized if there is a window.

Volley ventilation through windows and doors

When volley airing within a few minutes of normal moisture away, preventing wetting bath rooms made from wood

The venting baths are involved:

  • window;
  • the air holes in the foundation;
  • the holes in the wall / ceiling;
  • door and gap under them.

The solution with the installation of windows in the steam room is very good, another thing that is not always possible to implement it. It is in such cases will pick up other options for the ventilation of the room.

Inlet air opening

Devices for the fresh air and the outflow of exhaust must be provided with all the bath room, including steam room and a relaxation room

Flue yield the attic

Exhaust openings are made in the top of the bath rooms or in the ceiling, if the bath undeveloped pitched roof. In the second case the output is the air through the attic

Hatch in the ceiling for ventilation

By opening the hatch in the top ceiling for ventilating bath, increase the outflow of carbon dioxide and air, from which the oxygen is burned. It was replaced by a fresh batch comes through the supply opening

Fabric exhaust valve openings

Monitor the performance of natural exhaust system helps tissue valve, which cover the opening when it is required to reduce the flow

The air holes in the base are not often able to use. Especially if a steam room owner has decided to allocate one of the rooms of the house, the foundation of which is not equipped with special holes. Here come to the aid forced ventilation with a carefully chosen location scheme supply and exhaust openings.

It would be desirable to protect the room from the steam leakage, carefully covering the vapor barrier materials and a tight-fitting doors, do so not worth it. The door to the steam room must be sure to leave a gap of 2-3 cm, and not otherwise.

Gap under the sauna door

Gap under the door of the steam room will provide a more uniform flow of air that will benefit the people hovering

For air flow is desirable to make holes in the bottom of the room, communicating with the street. After all, the room needs to be clean and fresh air, especially if the room is located outside the city near the coniferous or deciduous forest.

Openings intended for the removal of exhaust air, is arranged in the upper part of the walls, opposing walls with supply valves. Moreover, their height depends on the chosen ventilation circuit and starts from 80 cm above the floor level or more. It is also possible exhaust valve device in the ceiling with the output ventkanala the roof.

Supply opening in the bath

Blowing holes close valves, gate valves, it was convenient to manage them in the process of receiving bath treatment

Components for the construction of ventilation

To create favorable conditions in the sauna bath and in all other areas to be properly arrange the ventilation system. Otherwise, neither of which comfort and speech can not be.

Components used for the ventilation device are as follows:

  • a vent valve;
  • valve;
  • lattice;
  • mosquito / protective mesh;
  • airbox;
  • or galvanized corrugated duct;
  • fan;
  • hygrometer, thermometer;
  • a metal tape, clip, foam, sealant, mounting and other consumables for mounting and registration of the input and output openings.

The vents for ventilation in the bath put on the supply and exhaust openings. They come in different sizes, shapes and materials. So do not be difficult to choose a valve that is ideal for color.

Twist-Off Valves for ventilation

Valves for ventilation are untwisted / curl, are most convenient in use, allow to leave very small gap for receipt of a micro air servings

Catches are also found in various designs. They need to open / close the holes if necessary. Often domestic craftsmen make a homemade design that is not worse than coping with the function remove / inflow of air masses from the premises.

Mesh grille and need to protect the vent from getting into the rodents, moths, mosquitoes, and other animals. Lattice selected from wood, heat-resistant plastic, and the grid is most often made of metal.

Metal rack bath

An array of soft material impractical to put on the intake hole - rodents can spoil it. Better to choose the metal options

Airbox equip a wall niche or if conditions do not permit, paving on top, for example, if the material aerated concrete walls used. The box can make from scrap materials or used as a duct or galvanized corrugated pipe. Plastic analogues are not suitable for steam - must take into account the temperature to which the room will be heated.

The fan in the bath is used for both the inflow and to the hood. The best is to use it only in one direction - to the inflow or removal of air masses.

Buy need refractory device that is specifically designed for baths and saunas with IP 44 and higher. Do not forget about the specifics of the room - there are a lot of steam and high temperature.

Ventilation in the sauna with a swimming pool

If the room is equipped pool bath, that can not do without mechanical ventilation. Swimming pool - is an extra room where the clock water evaporates. A tree is not like

Consumables used during assembly for mounting duct, the installation arrangement of air ducts and valves, fans. Hygrometer and thermometer is necessary to effectively use the ventilation system.

If arranged with mechanical ventilation, climate equipment, there is integrated a temperature sensor and a humidity regulator. Based on the actual performance of devices the system runs an exhaust fan or open the supply valve.

Apparatus bath ventilated floors

Installation of ventilated floor plan is still in the construction phase. Implement this type of ventilation together with the construction of the rough, then the finished floor, for picking themselves the most acceptable option for the price

Properly invested ventilation will provide a comfortable stay in every room bath, not clouded by external smells and water droplets running down the walls and falling over the collar from the ceiling.

Another important condition for long life - timely and complete drying after use. It is up to the implementation of this item depends on how long an bath and whether replacing rotted boards need new next 3-5 years.

Rotting bath ceiling

When there is no ventilation, and the owner of the bath seals the doors and windows after use, can be a year to detect the fungus, mold, rot

Conclusions and useful videos on the topic

Effective ventilation circuit organization in the steam room:

Options ventilation device in the new bath:

The freestanding bath is realized ventilation of the interior and attic. Also in the basement there are air holes, and to improve air exchange between the steam room and relaxation room is used fan - all this can be seen in the video:

The lack of air ducts in the bath can result in costly troubles:

For rational and long-term use of the bath it is important to equip the system of its ventilation. It is necessary to choose the most viable option under suitable specific conditions capable of providing a supply of fresh air and removal of waste in the required volume. If the broken bath dry and comfortable heated and nothing drips on your head, then the ventilation problem could cope perfectly well.
