Ventilation in the bathroom and toilet: features of the device

The bathroom is a room with high humidity, and condensation is often formed in the bathroom due to the high temperature of the water during bathing. In order for dry walls, floor and ceiling to remain in the room, it is important to ventilate the room well, otherwise the mold will start to develop, and being in the bathroom will not only be unpleasant, but also dangerous. Having properly equipped the ventilation system, you can save yourself from the unpleasant consequences of its absence.

Any room in an apartment or house should not only be habitable, but also be used with comfort. So, if there are no windows in the living room, the air will be stale and stale there, which will contribute to the development of pathogens, and the person who lives there will constantly be sick.

It is equally important to make sure that the stay in the toilet and shower is as comfortable. The bathroom can be both combined and separate, which, in turn, implies a different ventilation device. The hood for the bathroom and toilet should efficiently cope with its task, providing intensive air exchange and constancy of the temperature in the room. Ventilation is especially important in those conditions where a high level of humidity is present, because constant contact with water spoils any covering of the walls, floor or ceiling and causes the appearance of undesirable microorganisms on it that adversely affect human health.

In the toilet hood is needed to effectively remove unpleasant odor, which is very important for this room, especially in the conditions of the apartment. Regardless of the room in question, it is necessary to create optimal conditions for the existence of a person of any age.

Based on the different configurations of the rooms in the apartment or house, their dimensions, there are several ventilation options that can be installed in them. The easiest will be natural ventilation, which is laid in the process of housing construction, but if you want you can do it or upgrade later.Such a system helps to promote air masses, effectively renewing them indoors, while not requiring the installation of any electrical equipment.

The principle of its operation is that air ducts are installed on top of the room leading to the roof., the hot air in the room rises and falls into these secret paths due to the temperature difference. This principle has the name of convection and works quite effectively if there is a different temperature in the room and on the street.

When such a hood is created, it is necessary to provide some nuances.

• The duct must be positioned vertically. Each room in the room should have its own mine.
• If the rooms are located side by side and have similar specifics in the form of high humidity, large temperature differences and strong odor, then they can be combined with one ventilation shaft.
• Natural type of ventilation at a neutral temperature has a small burden, because it is desirable to do the air ducts with smooth walls.
• Being engaged in installing the ventilation yourself, it is better to take care that there are no sharp corners,which impede the passage of air and its output to the outside.
• One-story houses should have wiring near the ceiling, which goes to the attic and is displayed on the roof.

The air that is discharged from the room has a certain voltage and circulation, which is called the force of thrust.

Check the operation of ventilation in several ways.

• Bring the match to the ventilation. If there is a movement of the flame, then the ventilation is fully functional.
• Take a sheet of paper and bring to the ventilation. If he keeps on it, then the thrust is good, if he falls, the air is removed poorly. The indicators will be inaccurate if the air temperature in the room and on the street is approximately equal.

If natural ventilation is inefficient, it is advisable to use a reinforced version. Forced ventilation involves the presence of an electrical device in the form of a fan. Ceiling ventilation of this type must be equipped with a suitable apparatus that can cope with a given amount of air masses. For such a device, it is enough to have in the room one channel through which all the polluted air from the room will be discharged.To calculate the optimal power of the device, multiply the volume of the room, where the length is multiplied by the width and height of the room, by the frequency of use, which varies from 5 to 10, which is dictated by the number of people living in the room and using a bath, toilet or kitchen.

Using forced fans in the bathroom can be dangerous, because the contact of electrical appliances with moisture can cause a short circuit. In order not to risk the device performance and the safety of residents, it is necessary to install moisture-proof fans.

When choosing a fan, it is important to pay attention to various indicators.

• The presence of a humidity sensor, which itself calculates the time to turn on when the humidity threshold has been overcome. This type of inclusion helps to save on electricity.
• Fans with a timer allow you to set the ventilation on time, so as not to waste time on this, but to actively use the room under optimal and comfortable conditions.
• With the presence of a motion sensor that activates the fan, if there is someone in the room.
• A device with a check valve to prevent the ingress of polluted air from the environment into the room.

Modern devices can be equipped with smart technologies that have many functions and are easy to manage. Clever ventilation allows to achieve the desired result, even for people with disabilities. Exhaust ventilation can have an autonomous option and be located in the ventilation shaft of the bathroom, in the window in the kitchen or in any other place where it can take the air out of the room to the street. The operation of such a device is carried out on batteries, which means that there is no risk of short circuits and a threat to humans.

Having thought about installing a fan in the duct, you need to decide on the need for this device. If the hood copes with its work, then there is no point in mounting additional devices.

To understand how effective ventilation works, you can look at the following indicators:

• how much the windows and mirrors in the bathroom sweat during the shower;
• wet background of the room, the slow process of drying towels;
• the beginning of the development of the fungus in the seams of tiles, in the corner of the room and on the ceiling.

Check whether the ventilation of the air from the room is simple - for this you can take a match and watch the movement of the flame. If it does not move, then the air duct is clogged and needs to be cleaned. With a weak movement can be observed weak traction, which indicates the need to install a fan. It is important to carry out such a check under optimal conditions, when cold air is blowing outside, and the house is warm. It is in these conditions that the draft goes and one can judge the condition of the ventilation shafts. Ventilation must cope with a given amount of air in the room, because it is important to choose sufficiently powerful devices.

When installing a forced fan while it is turned on, you can clearly hear its noise. It buzzes quite noisy in case of improper installation, but if you do everything right, then the sound will be almost inaudible. The noise threshold for the bathroom is 25 dB. Noise can also occur due to the strong power of the device and the high speed of movement of the blades. Making a choice in favor of a product, it is important to pay attention to the performance indicators, because they will affect the rate of air exchange, and, importantly, the performance of additional functions, such as a timer or a motion sensor.

In order to make the right choice and install a suitable fan, it is important to know what exactly you need to pay attention to:

• Availability of certificates and quality assurance. The device must be safe and do its job well.
• Electrical parts of the hood should be placed in a plastic case that protects them from moisture and steam.
• The optimal level of power to quickly bring all the air in the room, updating it. If the bathroom is shared, then the hood must be more powerful in order to serve two rooms at once.

• Fans with a variety of sensors and a timer will attract fans of modern technology.
• It is important to correlate the size of the exhaust opening with the dimensions of the fan itself, so that it enters it, but at the same time it does not hang out.
• The choice of ventilation devices is better to produce among the range of well-known brands that have proven themselves in the market.
• Selection of the fan is carried out taking into account the noise of the device, which should not be above 25 decibels.
• Selection of a good device for the best price.

The most favorable fan option will be a device that runs on ball bearings.that makes them quiet and maximizes its service life. It is most convenient to use a fan with a motion sensor and a humidity level, which is turned on by itself at the right time, which does not require any human participation and ensures the latter a comfortable use of the room.

If you need to install a fan in the bathroom with your own hands,it is easiest to purchase a suitable device for this, place it in a ventilation shaft, connect it to electricity and fix it to a wall. If possible, it is better to buy a fan that is equipped with a humidity sensor, which ensures its inclusion at the right time. The apartment usually provides special air ducts in which the grid is mounted for natural ventilation or a fan for forced. If there is no such construction, then it should be done independently, doing it in the wall opening or in the ceiling. This is true for a private house, which was built as a summer residence and did not assume a year-round stay.

If the bathroom has a window, this is an opportunity to ventilate the space., but it is much more effective to add an electric appliance to it for a quick pumping of air and saturation of the room with freshness. In those cases when there is no ventilation and even a window is not provided, the output of the shaft will be through the wall of the house along the top, in the direction of the roof. Having assembled all the structures, you need to check how well the air goes over them, and only then mount the fan itself.In the process of work, something can clog the channel or partially clog it, so it is important to check the permeability of both self-made airways and those that were provided during construction.

Selection of the fan is made on the existing hole in the wall. If they do not match, you will have to either expand it or compact it. Installation is done by removing the grille and fixing all the necessary wires. Fix the equipment can be screws or liquid nails. When everything is ready, you must install the grille in place and cover the joint between the fan and the wall with a sealant.

Ventilation for the bathroom and toilet may be ready and be in the wall, and may be absent, then you need to mount it yourself. The choice of materials in this case plays a big role. Air ducts may have a different appearance, be round or straight. The main material for their manufacture is steel, it can have a different thickness depending on what temperature the air will have and how much it will move.

The main parts are the piping for the passage of airbut apart from them, it is important to use also shaped parts, due to which the turns and bends of the structures are formed. For areas where the ventilation shaft passes from the outside, you can use copper, textile and plastic parts, which will have not only a high quality factor, but also a decorative effect.

To fix the air ducts, you can use a flange, a bandage, a bell or a coupling. Having made a plan for future ventilation and having decided on the type of attachment and future materials, you can start work. The next important step will be the selection of the fan itself and its components.

Each ventilation system designed to clean the air must have a filter that can be of several types:

• dry porous;
• porous dipped;
• electric.

Another component is a silencer that allows you to make the fan less noticeable and loud.Usually they are made of tin in the form of two cylinders, which separates the absorbent material. In some cases, it is advisable to install dampers that allow air to open when they open and stop when they close.

By itself, a fan for a bathroom or toilet can be of four types.

• Axial. Used in apartments and houses, has high efficiency with relatively simple installation.
• Centrifugal. Applied to large industrial facilities, because the ventilation capacity of this device is very powerful and can recycle a huge stream of air, while using the same energy resource.

• Channel. Installed in the air duct itself. These devices have a humidity sensor and shutdown. Most often, the device is placed in a plastic case, which makes it possible to use it in a sauna or swimming pool.
• Domestic. Serves for serving the kitchen or bathroom in the apartments. For such rooms it is recommended to choose a device equipped with a check valve, which will not allow air from the toilet or kitchen to get into other rooms.

To install a fan, you must follow certain instructions. Often, on the package itself with a fan, there are already some recommendations on how to properly mount it. However, before you can mount something, you need to check the efficiency of the ventilation shaft, whether it copes well with the air intake and if it fully removes it from the room. If there are any problems with the air flow, you must carefully check the canals and clean them.

To install the fan first thing you need to remove the decorative grille., then try on the fan to a specific duct. It is important to fix the device in the hole with a sealant or special glue, but the most reliable option would be to use screws. Once the main fixture has been made, it is important to take care that no minor flaws remain. Once everything is finished, you can put in place the grill and check the operation of the device.

If there is no ventilation shaft in the room, then it should be organized at least two meters high. It is advisable to position the outlet opposite the door or diagonally fromof them. This will help create the necessary air flow for active ventilation of the space. Fan performance can be selected as desired. It can turn on automatically if it has the appropriate devices, and you can activate it by turning on the switch of the fan itself or combined with the light in the bathroom.

The choice of the fan must be justified, so that its power is enough for the bathroom, and the design of the lattice is selected on the basis of the appearance of the space, in order to emphasize its style and supplement it if necessary. By installing such a device, you can extend the safety of all coatings in the bathroom and ensure comfortable and safe use of both the bath and the toilet.

If the fan is installed correctly, then there should be no problems with its work, and it will effectively cope with the amount of air intended for it in the room. However, if during the installation process mistakes were made or the work was done by an unqualified master without due attention, then very soon the first problems may appear.

Before you install the fan in the mine, it is important to check the cravings in it. If it is not there or it is weak, it is advisable to clean the entire system, otherwise the problem with time will only worsen, and to clean the moves you will need to dismantle the fan. Checking the traction, it is important to do two tests at once - one with the doors and windows open, the other with the doors closed to cut off access to a source of fresh air.

Combined bathroom with toilet requires a more powerful device, because it is important to correctly calculate the power of the device, choosing it. Knowing the area of ​​the entire bathroom, you can decide on the type of fan. Often, more powerful units have a larger size, because they need to pump a large amount of air at times. Choosing the size of the fan, it is important to know in advance the size of the vent hole, so that you do not have to expand it or put something in place for fixation.

If over time when the fan is turned on, problems start to appear and the device does not work, you need to check the wires and the switch, if it is the triggering element. When installing the fan, it is desirable to securely fasten all the cables so that they do not unwind with time,because during work there is a slight fluctuation of the surface, which can affect them, because over time the contacts will weaken and move away.

The correct height and location can guarantee optimum fan performance., and the cleared air ways will give free passage of air from the room out of its limits and its replacement with fresh and pure.

When choosing a fan, it is important to pay attention to many details. If the installation site is a bathroom, then the humidity level in it will be high enough, so you need to look for markings with letters IP, which mean additional protection of the case from moisture and are ready for moist air masses that will pass through it.

As for power, it is recommended not to take devices that have parameters less than 100 m3 / h. To save electricity, the most relevant will be models equipped with a motion sensor that turns on the device when someone appears in a bathroom or toilet and turns it off upon the disappearance of an object.If there is a desire to use a fan only in case of need, it is better to choose a device with a humidity sensor in the room, then the fan will start its operation at the moment as soon as the norm level is exceeded and stop when the air is fresh and clean.

If there is a desire to take a shower in a well-ventilated room, you can set the timer to automatically turn on the fan, which itself will turn off at a predetermined time by the owner himself. When choosing a fan for high-rise buildings, it is very important to check the presence of a check valve that will block foreign debris and dirty air, not letting it into the apartment.

Only a careful selection of the device will ensure the comfort of living in an apartment or house. and the use of the bathroom and toilet in compliance with all norms of humidity, clean air and the complete absence of harmful factors that appear when such norms are not observed.
