How do-it-yourself ventilation is built in the toilet in the country house. Rules and schemes for arranging ventilation for a country house Does an exhaust pipe help in an outdoor toilet

The fetid odors from the country "birdhouses" - closets annoy not only the owners of the buildings, but also pester the neighbors. This explains the desire of summer residents to build such a latrine so that it is always clean, dry and comfortable in it, and unpleasant odors do not pester.

Toilet Ventilation: Possible Solutions

Traditional country toilet with simple ventilation

Since it is impossible to tightly close the pit with the processes of fermentation of fecal waste, the optimal solution to the problem is to organize productive air exchange of the "birdhouse" itself, usually made of brick or wood, and the pit under it. It is there that sewage decomposes under the influence of anaerobic bacteria, and methane is released. Air exchange is achieved through the proper arrangement of the toilet, as well as the competent selection and installation of devices for organizing air circulation.

Attention! For correct installation ventilation, even at the stage of drawing up a toilet drawing, its type and placement of functional units are indicated. The frequency of air exchange should prevent a dangerous concentration of methane and its vapor poisoning.

Do-it-yourself ventilation in the toilet in the country house can be done in two ways:

  1. The natural way. Air currents move by gravity, induced by the wind, arising from different air volumes in terms of pressure. Injection units are not used, energy is not wasted.
  2. By mechanical means. Fans, air heaters, etc. are used to move air.

Closet ventilation without the use of mechanical devices


The scheme of the simplest ventilation in a country / rural toilet

In a compact toilet cubicle, the window plays the role of a source of light penetration during the day and serves as an opening for air to move through it. Despite the fact that the geometry of the window, the shape is chosen according to the individual preferences of the owner, there are several points that you need to pay attention to:

  • The window should be "in work" all the time. To do this, you do not need to glass it. If the closet is operated in cold weather, air flows can be minimized by covering the opening with a sheet of plywood.
  • An open hole will be protected from snow and rain getting into it, if placed as close as possible to the roof, under the very visor.
  • When arranging an additional hole for ventilation, it is best to cut it in the toilet door (lower part) or in one of the walls.
  • Protection in the form of mesh, gauze, curtains will prevent insects from entering the toilet.
  • Installing a toilet bowl involves supplying an extract to it through the floor or connecting a pipe to the toilet bowl.
  • For better circulation, slotted holes disguised as gratings are arranged in the lower part of the walls of the building.

Natural pit hood


Pit toilet ventilation scheme

By providing an exhaust pit, it is possible to remove the gas accumulating in it outside the toilet (to the atmosphere), and not into the stall. You need to perform such a withdrawal in this order:

  • A hole of the desired section is formed in the pit.
  • According to the height of the back wall of the toilet, where the hood will be located, dowels and clamps or brackets are fixed.
  • A pipe is installed (asbestos-cement or PVC with a diameter of 100 mm). Its length is taken taking into account the height of the toilet and the maximum possible filling level of the pit.
  • A deflector is attached to the top. Its diameter must be identical to the pipe section.

Economical septic tanks for summer cottages with a cesspool from a barrel

Solution as a cesspool to use storage tanks can be considered effective only when the ventilation in the toilet in the country house from the barrel in the form of a ventilation pipe will be at least 100 mm in cross section. It is removed above the ground by 0.5 m and removes the accumulated methane. In the absence of ventilation, the processes occurring inside the barrel can break it. With a relatively low efficiency and dependence on climate, weather, such toilets in summer cottages are popular due to their simple installation and cost-free operation.

Natural supply and exhaust method


The pipe can be output in this way

A greater effect on removing stench from the cesspool is achieved with natural supply and exhaust ventilation. Except installed toilet some summer residents make another hole in the floor. Through these two inlets, air enters the pit, and leaves through the mounted pipe. It turns out two branches: from the closet and the pit. They are made of gray PVC pipes with a cross section of 100 mm. The pipe must be calculated in length so that one end falls into the pit, and the other (upper) rises 0.3 above the roof. It is this height that should provide sufficient air removal power. With its lack, you can apply methods to increase traction in the pipe:

  • Steal in a dark (preferably black) color exhaust pipe. Here the air duct rises slightly above the roof of the closet. The attracted rays of the sun heat the chimney and urge unpleasant odors to rise upwards.
  • The pipe is also heated with the help of a light bulb placed in it.
  • Install an exhaust device at the end of the outer part of the pipe (hood) to suck air from the booth. A puff of side wind creates air pressure between the pipe and the deflector, increasing traction.

For information! One way to reduce or even eliminate the penetration of stench into the toilet cubicle is to place the pit and cubicle at some distance. Laid between them sewage pipe connect the toilet in the "birdhouse" and the cesspool. The use of a tee makes it possible to install a ventilation pipe. For the disposal of sewage with such an organization of air exchange, a water supply is required.

Forced ventilation


The top of the ventilation pipe must be protected by a visor

A do-it-yourself mounted mechanical hood in the toilet in the country house will be more effective if:

  • forced exchange takes place in the booth, but not in the pit;
  • unpleasant odors, fumes are continuously removed;
  • circulation provides the required air exchange rate;
  • the power plant works regardless of the weather and seasons.

Significant "cons" - dependence on electricity and significant capital investments.

Organization of ventilation of the latrine ventilation device installed in the same window and connected by a cable to the mains - one of the types of forced air exchange. To control the air supply, you must also install a switch. The wiring is insulated from moisture penetration. It is laid on the outer side of the structure along the roof from the attic near standing house. Fan power in 30W window opening enough for small cabin dimensions (about 2 sq.m.). Depending on the shape and size of the window opening, the installation model is also selected. It is necessary not to forget to close the channels (exhaust, supply) with a protective mesh or grille. The fan connected to the network is checked in operation.

As for the septic pit, in its closed volume it is not enough fresh air. Therefore, a forced ventilation system is not placed directly in the pit. A fan is installed in the lowered pipe. He creates a breakdown. Air suction goes through the cabin.

It can be made easier. You will need to install a low-power duct fan in the hood: only 3 - 5 watts. The sensor regulates the speed of rotation of the blades. It is mounted directly inside the toilet. The desired speed of the exhaust air (thrust) is manually adjusted.

What type of ventilation for a country toilet to choose - everyone decides, based on financial capabilities, expediency of use.

How to make a ventilation hood in the toilet in the country and at home with your own hands

It would seem - why in the country ventilation? There is plenty of fresh air around, just open the windows and breathe! An - no. There is no way to avoid drafts, and there is no way to control the air flow. Most country houses are mothballed for the winter. “Visiting” cottages for the New Year holidays, many owners feel a musty atmosphere and heavy air, the smell of mold. This is the result of a lack of air exchange, so ventilation in country house needed.

In ancient times, when houses were built entirely of logs, no one thought about how to make ventilation in the country. Because the "live" wood passed fresh air from the street through itself. He penetrated into the window cracks, and into the caulked joints between the logs. Unplastered walls supported optimal humidity and temperature. An important element of ventilation country house served as an oven. Exhaust air was drawn through the chimney.

Thus, the design of a house built according to old models implies natural ventilation.

The toilet in the country also needs ventilation, especially if the cottage is used all year round, and faeces accumulate in the cesspool. How to make effective ventilation in your favorite country house, spending a minimum of money?

Stoves and fireplaces for ventilation of small cottages

Natural ventilation oven

Modern execution of ancient building technologies: it is cottage from a bar, with a fireplace or a stove and always wooden window frames. Such a country house is ventilated perfectly without special investments.

Wall material will not let the summer heat into the rooms. In winter, the stove will serve as a hood and heater simultaneously. But in order to assemble such a dacha ventilation system with your own hands, you will need the skills of a stove-maker.

A good option for ventilation in the country can be a fireplace. The air flow will go through the cracks in the frames or open windows (if the windows are made of plastic). Blowing - through the chimney.

At the same time, the problem of heating is also solved for country house used all year round.

Such a system is suitable for a building made of any materials, a small area and used mainly in the warm season.

Mechanical dacha ventilation system

Scheme of mechanical ventilation

In the country, mechanical ventilation is justified in the following cases:

  • large house;
  • house 2 or 3 storey;
  • the house was built using frame technology, which excludes natural air exchange.

Forced-type ventilation in a country house can be done completely mechanical or combined.

The combined system is easier to install, it will cost less, including during operation.

Forced air outflow

The supply part of the combined ventilation of a country house can be equipped with your own hands.

If the windows are plastic, supply valves are installed in them. These devices are on sale, they are inexpensive. Exist various models window inlets. They are attached to the upper crossbar of the window sash.

The supply valve can be inserted directly into the wall of the house. This is a fairly simple mechanism, consisting of a pipe for which you will have to make a hole with a diameter of 5 cm and a damper that regulates the intensity of the air supply. In winter, the damper is closed as much as possible to avoid cooling the room. You should not buy complex valves with filters, because clean country air does not need to be cleaned.

Air outflow is provided mechanically. And only skilled craftsmen can handle this work of installing ventilation in a country house with their own hands. Exhaust ducts are extended from places of the greatest air pollution (for example, kitchens) to the attic. An exhaust fan is installed here, which throws the exhaust air out. A negative pressure is created in the house, due to which fresh air is drawn through the supply valves.

Cons of mechanical extraction:

  • during a long absence of the owners, the house remains without ventilation;
  • ventilation ducts need to be hidden under beams or boxes;
  • additional power consumption for air extraction;
  • it is advisable to select structural elements with the help of a professional.

It is better to entrust the calculation of the thickness of the air ducts and the fan power to a fan engineer.

Forced air supply

You can go the more expensive way by equipping your own hands with a forced air supply to the cottage ventilation system.

At the level of 2 meters from the soil surface is installed Supply unit. The air from the street is collected in the chamber, where it is heated (if necessary) and supplied to the rooms by a fan.

There are two ways to heat the air:

  • electric heater;
  • heating pipe.

The second is much more practical, but it must be designed simultaneously with the planning of the heating system. The outflow is provided by ventilation vents in the kitchen, bathroom or toilet (if they are located in the house).

Do-it-yourself supply ventilation of the cottage

Air flows at supply ventilation Houses

Do-it-yourself construction of forced ventilation of a summer house is a complex and rather expensive process. But some craftsmen, thinking about how the ventilation of the dacha is done, come to original solutions. The air supply is carried out with the help of an air intake. It is mounted from the north wall. The unit consists of a pair duct fans and two pipes through which air goes into the body of an old but sealed refrigerator. Here, 2 radiators from the car are connected, connected to the recuperator. 2 - 4 pipes are sent to each room of the cottage (depending on the power of the installation and the area of ​​\u200b\u200bthe room) with ventilation grilles. Supply grilles are placed 0.2 - 0.3 m from the floor.

The outflow of air is carried out in a natural way. High blood pressure inside the rooms squeezes air into the corridors, kitchens and bathrooms. Ventilation pipes are equipped here.

Caring owners use waste warm air in cold weather to heat the greenhouse. Those who want to take advantage of their experience will have to run the ventilation pipe not up through the roof, but in the direction of the greenhouse. The air will be evacuated forcibly by the “snail” pump.

Country house floor ventilation

To ensure good ventilation of the country house, you should also take care of air exchange in the underground. Ventilation of the floor in the country house protects it from decay and the whole house from distortions, prolonging the service life.

If the basement is not planned, the ventilation of the floor of the country cottage is provided by a system of vents (holes) in the basement. Most often, country houses are built with basements. The vents are left at different heights of the plinth, which improves the movement of air flows. The size of the vents is usually 10 x 15 cm. The number of holes is calculated depending on the terrain, the architecture of the building, the wind rose and the climate.

Floor ventilation wooden dachas consists of wall grilles that are mounted above the floor vents (also called ventilation outlets).

The grate must be placed at the junction between the boards.

In this way, it is possible to make a recess in a smaller board, so the strength of the floor does not suffer.

Before installing sockets, you should definitely calculate the air flow pattern, which depends on the arrangement, type and power of heating devices.

Do not lay carpets, cabinets or sofas on top of the grilles for ventilation of the country floor.

To improve the movement of air in the subfield of a country house, ventilation plinths will also help.

Holes are drilled in the baseboards through which air circulates freely from the room to the basement. This is a simple and affordable method of building ventilation in a country house with your own hands. The holes in the baseboards should be up to 1.5 cm in diameter. They are installed along opposite walls. Sometimes a ventilation plinth is required on only one side of the room, and a ventilation pipe is used to ensure sufficient air movement. Its exit is located 1.5 meters above the roof.

Try to make such ventilation of a country house with your own hands, just ask a specialist to make the necessary calculations.

Do-it-yourself ventilation in the country toilet

Scheme of ventilation of a country toilet

Most country toilets are built like a cesspool, which has a serious drawback - these are fetid gases that appear as a result of fermentation of feces. It is impossible to hermetically close the pit, therefore, in country toilet ventilation is required.

You can do all the work on installing the ventilation of the toilet in the country with your own hands. The ventilation of a country toilet is usually a single pipe leading from a pit along rear wall toilet. It ends 75 cm above the roof level. Pipes made of PVC or asbestos cement with a diameter of 10 cm are used. Metal brackets are convenient as fasteners.

A special hole for ventilation is provided in the cesspool, where the pipe is installed even before concreting. However, sometimes such a ventilation scheme for a country toilet is not always effective and odors penetrate into the cabin. Can be assembled with my own hands ventilation of the cabin of the country toilet. To do this, you need to purchase:

  • two pieces of PVC pipe 0.5 m and 2 m with a diameter of 11 cm;
  • gusset 90 degrees;
  • umbrella or deflector;
  • decorative lattice;
  • fixture.

The exhaust hole for ventilation of the toilet in the country is drilled in the wall, as close as possible to the roof. The diameter of the hole must match the diameter of the pipe. The pipes are connected with a corner, a short piece is inserted into the hole. An extra piece of pipe from the inside of the room is sawn off. A deflector or umbrella is put on the upper cut of a long pipe, using a level, it is necessary to check the vertical position of the pipe, after which it is attached to the wall with long screws and clamps. A ventilation grill is installed at the outlet of the pipe inside the toilet. To prevent a blow in the slot, they are filled with silicone or mounting foam.

To ensure the flow of clean air into the booth, a small hole is made on the opposite wall (from the one where the exhaust pipe was inserted). It should be no higher than 0.2 m from the floor level and covered with decorative ventilation grilles.

The ventilation of an outdoor toilet will work according to the following principle: fresh cool air enters the cubicle, rises up along with unpleasant odors and goes out into the street. But before you make the ventilation of the toilet cubicle in the country, you need to take care of the removal of gases from the cesspool. Otherwise, do-it-yourself ventilation of the country toilet will not be effective enough to deal with the stench.

Ventilation in the country toilet

During the construction of a toilet and a shower in a suburban area, we missed the moment when it was necessary to make ventilation in the country toilet. After six months of operation of this important facility, we decided to correct this oversight.

Ventilation issues in the design of the country toilet and shower were taken into account, but not the cabins, but the cesspool. We removed a ventilation pipe from it, through which an unpleasant smell was supposed to go out into the street. But, perhaps, the room is made airtight, or the seat cover does not close tightly, but there were sometimes extraneous smells in the cabin of the country toilet. To get rid of them, we decided to ventilate the country toilet, directly to the cabin itself.

WE MAKE VENTILATION OF THE COUNTRY TOILET

For the ventilation device, we need: sewer plastic pipes with a diameter of 110 mm, a length of 2 m and 50 cm, a 90-degree connecting angle, an umbrella for rain protection, a decorative ventilation grill, clamps.

The first step in the wall of the building is to drill a large diameter hole for ventilation. Since we built the country toilet from a board 20 mm thick, in order to cut through it, we need a metal cutting crown with a diameter of 120 mm. We mark the place where the exhaust hole will be located (according to the law of physics, warm air rises from the bottom up, so the hood must be done in the upper part of the room), fix the crown on the drill and drill 2 holes, outside the country toilet and inside the cabin. After a window appeared for a few seconds, we admire the winter landscape of the Russian village and continue to work further.

We connect the pipes to each other using a 90 degree transitional corner. Insert the resulting structure into the hole, make a mark with a pencil and cut off the excess from a short piece of pipe. Now we will fix the ventilation system on the wall of the building. The distance between them is 13 cm. To fix the connecting clamp, take a piece of metal-plastic, cut it 13 cm long (it will be used as a stop between the clamp and the wall of the country toilet) and fasten it to the wall using a 15 cm self-tapping screw. We will also fasten the second clamp.
We snap the ventilation pipes into the fixtures, not forgetting to put an umbrella on top from natural precipitation. Check the system vertical with building level.

In continuation of the work, we will fasten the ventilation grill inside the room to a couple of screws. The gaps between the pipe and the wall can be filled with mounting foam or cover up silicone sealant.

Now let's drill a hole in the wall from below for access to the fresh air toilet to make a small draft in the cubicle.

We close it on both sides with decorative grilles, screwing them onto self-tapping screws.
Fresh air, entering from below into the room through the ventilation window, rises up and exits through the hood, taking with it extraneous odors.

This completes the installation of the ventilation system for the country toilet. The unpleasant smell from the cabin will now go outside.

Types and features of ventilation in the country toilet

You have your own summer cottage and it is imperative to build a toilet on it. Whatever type of toilet you choose, whether it is built of wood or brick, the issue of creating a ventilation system always remains relevant. Ventilation in the country toilet - quite important point and it is necessary to approach its creation with all seriousness.

A toilet that is separate from other buildings should not cause inconvenience not only to its owners, but also to neighbors. Most often, these problems are associated with unpleasant odors that spread several meters around him. We want to tell you how to get rid of all these odors. The toilet in the summer cottage must always be kept clean, but there is little guarantee that it will not contain odors, so it is important to make good ventilation that will ventilate the air well and not cause inconvenience to you and your neighbors.

What types of ventilation are there?

Ventilation in the country toilet is of two types:

  • natural;
  • Artificial.

The first type is provided without any additional mechanisms or devices, but as a result of natural processes: it depends not only on the direction of the air flow, but also on internal and external pressure.

But forced ventilation in the toilet is provided only with the help of special systems, this also applies to those that are connected to electricity. If you decide to build a toilet yourself, then you can handle ventilation without the help of a professional.

natural ventilation

You can equip the natural type with the help of a window or a special hole, which is located at the bottom of one of the walls. If you decide to make a window, then place it as close to the roof as possible or equip it with a special visor. This is necessary in order to protect your building from rain, leaves and dirt getting inside.

It would also be appropriate to close it mosquito net to keep insects out. And if you want not only to make a window, but also an additional hole in the wall, then make it at the bottom of the door or in the wall. Be sure to cover this hole with a special grate.

forced type

Forced ventilation, also called artificial, is created using special pipe or a box that supplies fresh air to the room, and removes an unpleasant odor. You can choose any pipe made of metal or plastic. One end of it should be lowered into the pit, and the other should rise a couple of meters above the roof. It is best if the pipe is installed outside the building. If you installed a toilet in a toilet on the street, then the pipe must be passed through a hole in the floor or attached to the toilet, and if you have a toilet with a pit, then it is better to carry out ventilation to it.

A box that provides good ventilation and a sufficient supply of fresh air inside the cabin is a special fan. For such a small structure, it is necessary to choose it with a power of no more than 5W. The fan is installed inside the pipe, so that the sensor responsible for the rotation speed is inside the cabin.

How to make a hood in the toilet from the boards?

In our modern time, many owners of private houses are trying to equip their houses with a bathroom, but there are also those who, in the old fashioned way, put wooden toilets on the site. So that you and your neighbors are not disturbed by extraneous odors emanating from it, it is necessary to make good ventilation.

Ventilation in a wooden country toilet is done according to a simple scheme, most often the owners choose a natural type. They equip the booth with a window or a hole in the wall. If someone is not satisfied with this type, then a forced system can also be made, no great forces and special skills are required. Everyone can install the pipe, the main thing is to correctly direct one end into the cesspool, and raise the other a couple of meters up above the roof of the cabin.

Hood in a brick cabin

Ventilation in a brick country toilet can also be both natural and artificial, you can equip a window in the wall or make a hole in it closer to the floor. Or, as in the previous case, equip it with a ventilation pipe, into which a fan was previously inserted. But let's take a closer look at how to make ventilation in the toilet on your own without the help of a specialist and so that it is effective and durable?

If you are about to start building a toilet on your personal plot, separate from other buildings, then you need to initial stage construction work to take care of ventilation. Before removing the walls of the building, make a ventilation pipe for the pit. With its help, you can protect not only yourself, but also your neighbors from extraneous odors that go out into the street, and not gather in a booth. But you should also take care of ventilation inside the building, if the building is solid, with tightly closing doors, and the lid most often remains open, then all unpleasant odors will accumulate inside.

Installation of the ventilation system

Do-it-yourself ventilation in the toilet is a simple matter, the main thing is to correctly calculate and install everything. In order to install special ventilation pipes, you just need to purchase a plastic pipe with a diameter of 100 mm in a hardware store. You will also need a 90 degree connecting angle. Do not forget about a protective metal or plastic umbrella that will protect your ventilation from dust, dirt and precipitation. Also, a special grille may be suitable for these purposes.

You need to make a hole in one of the walls, it will serve as the basis for the future ventilation system. Everyone knows that warm air always rises, so it is more expedient to install the hood at the highest point.

Ventilation installation

You have already made a hole, now you need to install a pipe, if you have more than one pipe, but several, then you can connect them together using transitional corners, now install assembled structure into the prepared hole. Excess parts can be cut off. Be sure to fix the ventilation system to the wall, special clamps are suitable for this purpose. Put an umbrella on top of the pipe to protect it from moisture and debris.

Inside you can put a grate, so your ventilation system is ready. Now cover all the cracks and defects on the wall. Slots can be sealed with mounting foam or sealant, and covered with cement on top.

But that's not all, in order for your ventilation to work and give the desired result, you need to create an additional draft that will help bring odors out. Therefore, you additionally need to make a hole at the bottom of one of the walls. After that, do not forget to close it with a decorative grill, in this way you can create ideal conditions for the operation of your ventilation system.

  1. Before building a country toilet, choose the right place, it is best if it is longer from buildings and located in a lowland.
  2. When making ventilation, it is better to calculate everything in advance and do all the steps without missing anything, only in this case you can be sure that extraneous odors will not bother you and your neighbors.
  3. The best material for a country toilet is wood, because thanks to the gaps between the boards, you can create additional ventilation, but still this will not be enough, so supplement the building with forced ventilation.
  4. Today, construction stores offer a wide range of modern forced hoods, for example, you can buy a decorative grille with a fan built into it. This wonderful device can be easily built into your country toilet and thus equipped with a high-quality ventilation system. And this is not all the opportunities that manufacturers offer their consumers.

Our article talked about how to properly install and design ventilation in an outdoor toilet. There is nothing difficult in installation, so each owner country house will be able to independently carry out the installation, and thanks to the manufacturers, you can purchase new ultra-modern ventilation systems that will help to efficiently remove odors and deliver a fresh smell to the toilet. Properly installed ventilation will allow you to be near the toilet and not feel its close presence.

Crafts for giving from waste material do it yourself

It would seem - why in the country ventilation? There is plenty of fresh air around, just open the windows and breathe! An - no. There is no way to avoid drafts, and there is no way to control the air flow. Most country houses are mothballed for the winter. “Visiting” cottages for the New Year holidays, many owners feel a musty atmosphere and heavy air, the smell of mold. This is the result of a lack of air exchange, so ventilation in a country house is needed.

In ancient times, when houses were built entirely of logs, no one thought about how to make ventilation in the country. Because the "live" wood passed fresh air from the street through itself. He penetrated into the window cracks, and into the caulked joints between the logs. Unplastered walls maintained optimum humidity and temperature. An important element of the ventilation of the country house was the stove. Exhaust air was drawn through the chimney.

Thus, the design of a house built according to old models implies natural ventilation.

The toilet in the country also needs ventilation, especially if the cottage is used all year round, and feces accumulate in the cesspool. How to make effective ventilation in your favorite country house, spending a minimum of money?

Stoves and fireplaces for ventilation of small cottages

Modern execution of ancient building technologies: this is a one-story house made of timber, with a fireplace or stove and, of course, wooden window frames. Such a country house is ventilated perfectly without special investments.

Wall material will not let the summer heat into the rooms. In winter, the stove will serve as a hood and a heater at the same time. But in order to assemble such a dacha ventilation system with your own hands, you will need the skills of a stove-maker.

A good option for ventilation in the country can be a fireplace. The air flow will go through the cracks in the frames or open windows (if the windows are made of plastic). Blowing - through the chimney.

At the same time, the problem of heating for a country house used all year round is also being solved.

Such a system is suitable for a building made of any materials, a small area and used mainly in the warm season.

Mechanical dacha ventilation system

In the country, mechanical ventilation is justified in the following cases:

  • large house;
  • house 2 or 3 storey;
  • the house was built using frame technology, which excludes natural air exchange.

Forced-type ventilation in a country house can be done completely mechanical or combined.

The combined system is easier to install, it will cost less, including during operation.

Forced air outflow

The supply part of the combined ventilation of a country house can be equipped with your own hands.

If the windows are plastic, supply valves are installed in them. These devices are on sale, they are inexpensive. There are various models of window inlet valves. They are attached to the upper crossbar of the window sash.

The supply valve can be inserted directly into the wall of the house. This is a fairly simple mechanism, consisting of a pipe for which you will have to make a hole with a diameter of 5 cm and a damper that regulates the intensity of the air supply. In winter, the damper is closed as much as possible to avoid cooling the room. You should not buy complex valves with filters, because clean country air does not need to be cleaned.

Air outflow is provided mechanically. And only skilled craftsmen can handle this work of installing ventilation in a country house with their own hands. Exhaust ducts are extended from places of the greatest air pollution (for example, kitchens) to the attic. An exhaust fan is installed here, which throws the exhaust air out. A negative pressure is created in the house, due to which fresh air is drawn through the supply valves.

Cons of mechanical extraction:

  • during a long absence of the owners, the house remains without ventilation;
  • ventilation ducts need to be hidden under beams or boxes;
  • additional power consumption for air extraction;
  • it is advisable to select structural elements with the help of a professional.

It is better to entrust the calculation of the thickness of the air ducts and the fan power to a fan engineer.

Forced air supply

You can go the more expensive way by equipping your own hands with a forced air supply to the cottage ventilation system.

An air handling unit is installed at a level of 2 meters from the soil surface. The air from the street is collected in the chamber, where it is heated (if necessary) and supplied to the rooms by a fan.

There are two ways to heat the air:

  • electric heater;
  • heating pipe.

The second is much more practical, but it must be designed simultaneously with the planning of the heating system.
The outflow is provided by ventilation vents in the kitchen, bathroom or toilet (if they are located in the house).

Do-it-yourself supply ventilation of the cottage

Do-it-yourself construction of forced ventilation of a summer house is a complex and rather expensive process. But some craftsmen, having thought about how the ventilation of the dacha is done, come to original solutions. The air supply is carried out with the help of an air intake. It is mounted from the north wall. The installation consists of a pair of duct fans and two pipes through which air enters the body of an old but sealed refrigerator. Here, 2 radiators from the car are connected, connected to the recuperator. 2 - 4 pipes are sent to each room of the cottage (depending on the power of the installation and the area of ​​\u200b\u200bthe room) with ventilation grilles. Supply grilles are placed 0.2 - 0.3 m from the floor.

The outflow of air is carried out in a natural way. Increased pressure inside the rooms squeezes air into the corridors, kitchens and bathrooms. Ventilation pipes are equipped here.

Prudent owners use the exhausted warm air in cold weather to heat the greenhouse. Those who want to take advantage of their experience will have to run the ventilation pipe not up through the roof, but in the direction of the greenhouse. The air will be evacuated forcibly by the “snail” pump.

Country house floor ventilation

To ensure good ventilation of the country house, you should also take care of air exchange in the underground. Ventilation of the floor in the country house protects it from decay and the whole house from distortions, prolonging the service life.

If the basement is not planned, the ventilation of the floor of the country cottage is provided by a system of vents (holes) in the basement. Most often, country houses are built with basements. The vents are left at different heights of the plinth, which improves the movement of air flows. The size of the vents is usually 10 x 15 cm. The number of holes is calculated depending on the terrain, the architecture of the building, the wind rose and the climate.

The ventilation of the floors of wooden dachas consists of wall gratings that are mounted above the air vents in the floor (also called ventilation sockets).

The grate must be placed at the junction between the boards.

In this way, it is possible to make a recess in a smaller board, so the strength of the floor does not suffer.

Before installing sockets, you should definitely calculate the air flow pattern, which depends on the arrangement, type and power of heating devices.

Do not lay carpets, cabinets or sofas on top of the grilles for ventilation of the country floor.

To improve the movement of air in the subfield of a country house, ventilation plinths will also help.

Holes are drilled in the baseboards through which air circulates freely from the room to the basement. This is a simple and affordable method of building ventilation in a country house with your own hands. The holes in the baseboards should be up to 1.5 cm in diameter. They are installed along opposite walls. Sometimes a ventilation plinth is required on only one side of the room, and a ventilation pipe is used to ensure sufficient air movement. Its exit is located 1.5 meters above the roof.

Try to make such ventilation of a country house with your own hands, just ask a specialist to make the necessary calculations.

Do-it-yourself ventilation in the country toilet

Most country toilets are built like a cesspool, which has a serious drawback - these are fetid gases that appear as a result of fermentation of feces. It is impossible to hermetically close the pit, so ventilation is necessary in the country toilet.

You can do all the work on installing the ventilation of the toilet in the country with your own hands. The ventilation of a country toilet is usually a single pipe leading from a pit along the back wall of the toilet. It ends 75 cm above the roof level. Pipes made of PVC or asbestos cement with a diameter of 10 cm are used. Metal brackets are convenient as fasteners.

A special hole for ventilation is provided in the cesspool, where the pipe is installed even before concreting. However, sometimes such a ventilation scheme for a country toilet is not always effective and odors penetrate into the cabin. You can assemble with your own hands the ventilation of the cabin of the country toilet. To do this, you need to purchase:

  • two pieces of PVC pipe 0.5 m and 2 m with a diameter of 11 cm;
  • 90 degree corner connection;
  • umbrella or deflector;
  • decorative lattice;
  • fixture.

The exhaust hole for ventilation of the toilet in the country is drilled in the wall, as close as possible to the roof. The diameter of the hole must match the diameter of the pipe. The pipes are connected with a corner, a short piece is inserted into the hole. An extra piece of pipe from the inside of the room is sawn off. A deflector or umbrella is put on the upper cut of a long pipe, using a level, it is necessary to check the vertical position of the pipe, after which it is attached to the wall with long screws and clamps. A ventilation grill is installed at the outlet of the pipe inside the toilet. To prevent blowing into the slots, they are filled with silicone or polyurethane foam.

To ensure the flow of clean air into the booth, a small hole is made on the opposite wall (from the one where the exhaust pipe was inserted). It should be no higher than 0.2 m from the floor level and covered with decorative ventilation grilles.

The ventilation of an outdoor toilet will work according to this principle: fresh cool air enters the cubicle, rises up along with unpleasant odors and goes outside. But before you make the ventilation of the toilet cubicle in the country, you need to take care of the removal of gases from the cesspool. Otherwise, do-it-yourself ventilation of the country toilet will not be effective enough to deal with the stench.

A street closet located in a summer cottage, in the vast majority of cases, is a compact building built of bricks or wood. The building above the cesspool is the only potential source of stench among fresh natural scents. It is impossible to hermetically cover the pit, so you need to take care of a constant flow of air. You can make ventilation in the country toilet with your own hands both during construction and later.

Types of ventilation systems and their principle of operation

The organization of air exchange depends on the chosen type of ventilation system, each of which has its own characteristics, advantages and disadvantages. In this regard, ventilation in the toilet in the country can be natural or forced.

Natural air circulation is carried out as a result of natural processes. Such ventilation is characterized by:

  • minimal financial costs;
  • ease of installation;
  • complete dependence on weather factors (wind, difference between internal and external pressure).

Type of toilet

Forced ventilation is a method of artificial ventilation, which includes the use of a special electrical equipment(fans, air conditioners, etc.).

Distinctive nuances of the system:

  • fast reverse of air masses;
  • does not depend on external factors;
  • relatively high cost;
  • the need for maintenance.

The intensity of ventilation is affected by the direction and strength of the wind.

Scheme of functioning of the air exchange system

How to properly install a ventilation system

It is possible to make effective ventilation of a country toilet with a cesspool with your own hands only with an integrated approach. Stable air circulation is required not only for the toilet cubicle, but also for the cesspool.

Installation of a natural ventilation system

The main element in the implementation of natural ventilation is most often a window provided in a door or wall. In order to prevent precipitation, it is recommended to place it at the highest possible level. It is not necessary to glaze the window, it is better to simply equip the opening with a mosquito net. It will also protect against mosquitoes, and will not interfere with the ventilation of the internal space.

You can increase the intensity of air exchange with the help of holes, which are best located in the lower part. It is important that the window is on the opposite side of the bottom holes

Air access to the cesspool is provided by a vertical pipe. The main condition for installation is the location of its lower part above the maximum filling level of the tank. The pipe must be at least 7 cm higher than the closet, and its circumference must be greater than 10 cm.

PVC pipe is ideal for this task. It is easy to install and allows you to quickly install a deflector on the outer end to prevent freezing of water.

The pipe is attached to the back of the building

Step-by-step instruction:

  1. Calculations are made to determine the required pipe length.
  2. With a shovel, they dig a passage to the cesspool.
  3. The pipe inserted into the dug hole is fixed to the wall of the building.
  4. The entry point is covered and rammed with sand.

Installation of a forced ventilation system

The fan extracts air from the toilet room here. If the booth area is about 2 square meters, a power plant with a power of 30 watts is quite suitable. The fan attached at the top must be powered. To do this, you must first carry out work on the connection of the electrical cable.

Fan for forced air exchange

Because of cesspool does not have sufficient air volume, it is not recommended to apply artificial ventilation to it. During the operation of the power plant, a rarefied atmosphere will be formed. And it can be restored only due to the air from the booth.

Having decided to do the ventilation of the country toilet with your own hands, it is very important to carry out everything construction works in strict accordance with technology and standards. In case of the slightest lack of self-confidence, it is strongly recommended to seek help from specialists.

Now few people build traditional huts with stoves, preferring modern engineering and architectural solutions. As the diverse and inexhaustible mail shows, ventilation problems in the minds of an ordinary owner of a country house occupy 47th place at best (I hope I will not offend anyone with this statement). And psychologically, this is easily explained: if a city dweller has escaped the boundaries of the metropolis and found himself in nature, then he will be provided with fresh air by definition.

Agree, why spend on the fan in the bathroom while there is no one there? Nothing at all! Therefore, such fans are equipped with different (according to the principle of operation) sensors - movement, humidity, etc. In the toilet, for example, it is reasonable to connect the fan to the switch.


In the toilet, for example, it is wise to connect the fan to the switch. Photo from allwantsimg.com

However, even in such a seemingly simple thing there are some nuances. So, for obvious reasons, it is advisable to extend the operation of the toilet fan for 5-10 minutes after turning off the light. A simple time switch included in the fan's electrical circuit will solve this delicate problem.

Wall fans remove air through channels provided in the walls during the construction of the house. If you are building a house again, then already in the project you should lay the possibility of optimal ventilation of the premises. To do this, it is better not to “scatter” on local ones, but to install them in the back room or in the attic. central exhaustfan, one for the whole cottage. It is connected to the exhaust objects by air ducts. For the central exhaust fan is structurally used centrifugal scheme, capable of "shoveling" air from several suction ducts. Such devices have a reduced noise level, and yet it is better to place them away from the bedroom and nursery.

We blow in both directions: supply and exhaust ventilation systems

It is difficult to find shortcomings in the considered systems in warm weather, but they are revealed with the advent of cold weather. The fact is that the air in winter goes inside without preheating. Of course, this leads to drafts and to local hypothermia of the rooms. Both in winter and in summer such systems not designed to clean the air from dust and odors. This set of shortcomings led to the creation of a more advanced supply and exhaust ventilation systems. It supplies the premises with a sufficient amount of purified and, if the weather requires it, heated fresh air. And the exhaust outputs with the help of fans.


The heat exchanger is the heart of the heat-saving ventilation system

It is reasonable to install such ventilation systems in houses next to freeways. They won't let the car stench poison country life. Such an installation is also required in rooms with a pool. But creating a comfortable microclimate in them is a big separate topic, which we will not consider today.

To force the supply of fresh air, it is reasonable to use factory monoblock air handling units rather than being self-employed. Although creative and skilled gardeners may not agree with me. For this we respect them.

Installations are mounted in the attic or outside the house. After cleaning and heat treatment, the air enters the rooms through a network of air ducts. The location of the air ducts should also be provided at the design stage. Most often they are placed behind a false ceiling. And this "eats" 10-15 cm of the height of the room.

Often used in conjunction with a supply unit roof exhaust fan. Of course, the supply unit and the exhaust fan are required to “pull” synchronously, otherwise there will be high or low pressure in the country house.

Let's move on to serious technology. That is, not to the "clumsy" distillation of air from empty to empty, but to the careful use of the thermal energy accumulated in the house. This is a ventilation system based on an energy-saving air handling unit with a plate heat exchanger or a rotary heat exchanger.

Traditionally, the installation is mounted in the attic. For air exchange, 2 duct networks are constructed:

  1. The intake of air from the garden, as well as its delivery from the installation to the premises, is carried out via the network supply air ducts.
  2. From the premises, the air is returned to the supply unit.
  3. And then goes outside the building over the network return ducts.
The outlet cuts of the inlet and return ducts are the only visible elements of these complex engineering systems, the presence of which is easy to determine by design ventilation grilles.


Air handling units with a heat exchanger reduce the cost of supply air heating by 10-70%. They are based on a plate cross-flow heat exchanger - a package of thin metal plates, between which gaps are left. The air removed from the room flows into every second gap between the plates, and fresh air goes through the remaining channels. Since the plates are very thin, they easily transfer heat from a heated air stream to a colder one.

Air handling units with rotary heat exchangers imported - the pinnacle of ventilation with maximum energy savings. But they are quite expensive and have not yet received distribution in ordinary dachas.


However, I would like to end the article with an encouraging story about a remarkable domestic development worthy of being embodied in metal. It was created in industrial Omsk, at the Ecoterm enterprise. The installation is called UVRK-50. To understand the essence of her work, we can draw an analogy with how we breathe on severe frost- through a warm woolen scarf. When exhaling, part of the heat and moisture is given to it, and when inhaling, fresh air, passing through matter, absorbs heat and moisture and returns them to the body. This ensures ventilation of the lungs with optimal energy saving.

When using this system, joint operation of two units in adjacent rooms. They alternate automatically switch on the different direction of flow and provide fresh clean air apartment of 60 sq. m with minimal energy loss. Power consumption does not exceed 30 W, and the noise level is 42 dB.


The inlet openings of the installation are lined with gratings, located both in the interior and on the facade of the dacha.

The unsatisfactory, I would say ugly state of air in rooms with closed double-glazed windows prompted the development of this design by Siberian craftsmen. And although UVRK-50 was created for urban conditions, there are no restrictions for its use in summer cottages.


Here you have a suburban light version of supply and exhaust ventilation. Honor and praise to these engineers!

How is the ventilation in your country house?

Ventilation of an apartment or a country house is an obligatory component of creating a normal microclimate. In addition to maintaining comfortable temperature and humidity requires high-quality and regular air exchange. Properly calculated ventilation in the bathroom and toilet is especially important.

Despite the common points, there is some difference between the ventilation of these rooms. If the main emphasis in ventilation in the toilet is on rapid air exchange, then it is more important for the bathroom to get rid of high humidity. Taking into account the requirements for air exchange rate optimal type ventilation can be considered supply and exhaust with forced action.

Exhaust ventilation for the bathroom and toilet: how to calculate the device of the system?

The peculiarity of air exchange in the bathroom leaves its mark on the calculations. Thinking about how to make ventilation in the bathroom or toilet when performing calculations, it is necessary to make certain adjustments. So, when choosing a fan, its performance is selected in such a way that it provides a complete change of the entire volume of air in the room 2 times per hour. For bathrooms, this indicator is selected with coefficients from 3 to 5.

This leads to an increase in energy costs. With continuous operation of the fan, even a small power for a year, this can amount to a considerable amount. It is possible to reduce these costs somewhat.

Extractor in the toilet with your own hands

The easiest way to do-it-yourself ventilation in the bathroom is to combine the fan on with the light switch. When you turn on the light in the bathroom and toilet, the fan starts working at the same time, and after the light goes out in these rooms, the fan turns off.

But if such a scheme is still suitable for a toilet, then a fairly high level of humidity remains in the bathroom for some time. There is a more complex scheme for how to make ventilation in the toilet and bathroom. The fan is switched on not directly, but through a special unit with a time delay relay. After turning off the light, the fan continues to run for a while. Moreover, the owners have the opportunity to adjust this interval according to their wishes. The adjustable range of autonomous operation of the fan can range from several tens of seconds to several minutes.

Ventilation in a country toilet: how to make a hood in a wooden stand-alone bathroom?

Many country houses have the same comfortable conditions as in city apartments. But if earlier a simple combined bathroom with a shower and a toilet was the ultimate dream, then in modern cottages equip full-fledged bathrooms, showers and baths with hydromassage. Bathroom ventilation in a private house is carried out almost in the same way as in an apartment with a slight amendment.

In an apartment building, ventilation from all apartments is led to a common channel, which has access to the roof of the house. With this arrangement, the air leaving the ventilation does not enter the lower apartments. In a private house, such a ventilation duct must be installed independently, and if the house has 2 or more floors and each has its own bathroom, then you have to calculate and create an integrated exhaust system. In some cases, a simplified ventilation scheme is allowed in the toilet of a private house. If there are no windows of rooms or other rooms above, then it is allowed to output the hood directly to outer wall. But it’s better to spend a little money so that later you don’t have to rebuild the ventilation system in an already built and finished house.

However, on many summer cottages you can find a separate toilet, built according to the classical scheme. And in this case, ventilation is necessary in the toilet in the country. Of course, it is done according to a simplified scheme and in the vast majority of cases it is of a natural type. But it would be a mistake to consider this task too simple.

Most owners limit themselves to installing this structure in the corner of the plot in the area of ​​outbuildings, and the ventilation device comes down to cutting out a heart or a rhombus on the door.

But at the same time, they do not take into account the interests of neighbors who can put their summer kitchen or guest house nearby. Sometimes this leads to serious conflicts. In order not to spoil relations with neighbors, it is enough to install a metal or plastic pipe with a head. The pipe can have a height of 1.5-2.5 meters relative to the roof, and this is quite enough for normal air removal.

Connection diagrams and ventilation output

How to choose the right exhaust unit for the toilet?

There is a ventilation hole in the toilet of each apartment. But, due to old mines, the resistance of the air column decreases and there may be problems with the removal of exhaust air. To provide good ventilation fans will be used in the toilet:

  • axial - contribute to the removal of large volumes of air in the absence of resistance;
  • channel - more difficult to install, but more efficient than axial;
  • centrifugal - provide good traction, but have large dimensions, their price is higher.

Which toilet hood will be effective?

If you have a standard vertical duct, it is better to buy a centrifugal fan. The duct model will be appropriate when combining several ventilation ducts. The economical axial unit is effective only in the presence of short horizontal ducts, it is suitable for installation on the top floors of a building.

What you need to know before laying ventilation in the bathroom?

Before ventilating the bathroom and toilet, it is necessary to examine the air supply channel. In private houses, it joins the hood, or is displayed directly on the roof.

In apartments of multi-storey buildings, all exhaust systems are connected to a single channel. It is located vertically, next to the bathroom and kitchen. The air vent is connected to an accelerating satellite channel, which, after 1-2 floors, enters the common ventilation shaft of the house.

Due to the difference in air temperature outside and inside the apartment, a draft is formed in the ventilation duct, which lifts the air from the apartment up the shaft. The air pressure in the room decreases and fresh air is supplied from the street, which makes up for the pressure difference.

But over time, the air ducts become clogged, and problems arise with the ventilation of apartments on the lower floors. Therefore, it is better to install a forced fan for the bathroom in the apartment.

Which ventilation device is suitable for a private house?

For effective air exchange, natural ventilation in a private house is not enough, it will be necessary to organize a forced system. To supply and purify fresh air, it uses supply devices with built-in fans, filters and a noise-absorbing mechanism. The outlet of the exhaust air can be carried out naturally, or with the help of exhaust devices. More efficient is supply and exhaust system. It can be additionally equipped with a heating unit, which will allow the incoming air to be heated to a comfortable temperature.

The supply and exhaust system belongs to energy-saving technologies, since air exchange in it can be carried out simultaneously with heat recovery (when part of the energy is returned for reuse).

The figure below shows a do-it-yourself ventilation scheme in a private house.

How to make ventilation in an already built house with an attic?

The ventilation system is laid at the design stage of the house, but it can also be laid in old houses. In this case, it would be preferable natural ventilation. It will ensure constant air exchange, without heat loss and the formation of drafts. To install an exhaust hood in a private house, it is necessary to punch a hole in the attic wall to the street, lay a ventilation duct along the facade, and bring it to the roof (at least 50 cm). In order for the walls of the pipe to match the walls of the house in terms of thermal conductivity, they must be insulated. To enhance natural draft, a deflector can be installed at the top of the ventilation duct.

All doors in the rooms of the house must have gaps at the bottom for air intake. And in the hood for the toilet and bathroom, it is better to equip it with a fan that facilitates the removal of exhaust air.

The figure shows a variant of laying exhaust pipes in a small house in the country.

What preventive measures will help to avoid the formation of mold in the bathroom?

During the operation of the bathroom, problems often arise with the accumulation of moisture, as a result of which mold forms, finishing elements become unusable, taps rust. Ventilation in the bathroom will help to avoid this, which will allow you to maintain optimal humidity and temperature conditions, and ensure proper air circulation in the room. She may be:

  • natural;
  • mechanical (forced).

The natural system assumes the presence of ventilation shafts, which are included in the building design. Their exits in the bathroom are closed with decorative bars. Fresh air enters the room through opened window, air vents at the bottom of the door.

However natural system does not always work effectively, in which case it should be completed exhaust fan. It is mounted in the shaft and turns on when necessary.

Below are different schemes for organizing the hood for the bathroom.

What is the difference between natural and forced exhaust systems?

Air exchange in a house / apartment can be arranged in two ways:

  • based on the movement of natural air currents - provides for the presence of cracks in the windows and doors for fresh air. The disadvantage of the system is the dependence on environmental factors (wind, temperature difference, pressure). Advantages - the ability to make additional wiring from the central highway;
  • by laying a mechanical exhaust system. Forced ventilation can be forced ventilation (air is supplied with the help of blowing devices, and is removed naturally) and supply and exhaust (air is supplied with the help of supply devices, and is removed with the help of exhaust devices).

Natural ventilation in houses with metal-plastic windows is ineffective, since air circulation is blocked. Suitable for houses up to 300 m2 supply system, and if Vacation home larger area? supply and exhaust.

How to connect a fan in the bathroom?

Bathroom fans can be connected in different ways. It depends on the chosen model and type of room. Their connections can be made by hand.

In order for the fan to turn on with the light, zero and ground are connected directly from the junction box, and the phase? after the switch, from which the phase wire for the lamp goes to the toilet.

Very convenient to use two-gang switch when one key turns on the light and the other? fan. The connection diagram will look like this.

To connect a fan with a timer, 4 wires are required. Contact L is connected to the direct phase from the transfer case and the light switch, Lt ? with lamp, on N ? zero, and the last conductor is grounded.

In order for the exhaust fan to operate from a humidity / motion sensor, it is necessary to connect the phase, zero and ground? directly from the transfer case, bypassing the switches.

During the construction and decoration of a private house, a lot of questions arise regarding the arrangement of internal communications, in particular, the installation of a ventilation system in the bathroom. To make a hood or not, the owner of the house should think about even when drawing up a project. But it’s still worth doing in order to avoid problems with fungi and damage to the finish in the bathroom in the future.

How to make a hood in a brick or wooden house

First you need to decide what kind of house you have: wooden or brick. Big difference. In a private house made of wood, most likely, natural shrinkage will occur over time. This must be taken into account when laying internal engineering networks to avoid warping.

Selection, installation, performance of ventilation in the toilet of a private house

Brick houses and buildings made of reinforced concrete will not sag.

To avoid displacement of the ventilation system, leave expansion gaps or install a special damping device.

It is simply necessary to install a hood in a private wooden house. Wood, like nothing else, is subject to negative impact excess moisture and suffer from condensation. Even if it's processed protective equipment on several layers, destruction cannot be avoided.

For more information, consider each type separately.

natural ventilation

During construction, ventilation ducts are constructed of bricks or ready-made plastic tubes are used for their manufacture, closed with decorative protective grilles.

There is another way. Installation on plastic windows a special nozzle with an inlet valve, which will provide additional outflow.

Some helpful tips if you decide to make natural ventilation in the bathroom:

  1. Combine channels leading from different rooms together if they are on the same floor level.
  2. Channels from different rooms can be connected together in the attic. But only if they are located on the same side of the house.
  3. Consider the fact that natural ventilation has a small head. Therefore, the inner surface of the air ducts must be made smooth. Avoid unnecessary bends and turns (radius of at least 10 cm).

Forced ventilation

It is necessary to make this type of hood in the bathroom in a private house if natural ventilation cannot cope.

Or it was not equipped properly and stopped working.

Safety requirements and installation in a wooden house:

  1. Choose for the arrangement of the ventilation duct exclusively non-combustible materials. When mounting, avoid contact with wood, use brackets.
  2. Buy an extract only with fire dampers, which, in the event of smoke, will limit the air supply.

Installation rules:

  1. The hood in the room should be made as high as possible.
  2. Install fans away from water to avoid short circuits.
  3. It is better to install ventilation before cosmetic finishing, when you can still hide the wires in the wall.
  4. To reduce the noise from the hood in the bathroom - pour a layer of silicone sealant.

    Or buy a silencer.

For more information, watch a video about arranging a bathroom in a wooden house.

Which fan to choose

When choosing a fan, it is necessary to calculate the size of the room. The required power of the device will depend on it. In addition, there are generally accepted sanitary standards for air supply:

  • l 25 m 3 per hour - for a separate bathroom;
  • l 50 m 3 per hour - for combined.

If there is no time to count, you can opt for models that remove from 60 to 250 cubic meters of air. This will be the most the best option. Also pay attention to the presence of a special product class label - IP. The index should be higher than 30. Choose a hood with automatic sensor motion for bathroom and toilet. It will cost more, but it will fully justify itself by saving on electricity in the future.

It is not so easy to make a hood in a private house, sometimes it is also difficult to choose equipment that would correspond to the declared price and have maximum efficiency. But some owners do not deserve to blame manufacturers ventilation systems in the manufacture of products that "do not pull." So, sometimes incorrect installation can reduce the efficiency of the device. Therefore, in addition to all other conditions, consider the presence of a gap under the door in the room where the installation is planned.
