How to choose and install a hood with a timer in the bathroom

The bathroom is the place where many of us relax after a hard day's work. And because of the vapors that appear during water procedures, vapors spread throughout the bathroom, which make it difficult to breathe. Another negative point is that after the perspiration dries, stains remain on all surfaces.

An exhaust fan with a timer draws all the vapors into the ventilation shaft

But this is not the worst thing, due to such an abundance of condensate, a fungus may appear in the bathroom, and this is already a problem, not to mention the fact that household appliances in the bath deteriorate due to the presence of a large amount of moisture and fungus . Therefore, if you are thinking about repairing the bathroom, then install a fan with a humidity sensor that will draw all the vapors into the ventilation shaft.

Types of household fans

A bathroom is a room with high humidity, therefore, in order to avoid the appearance of dampness and fungus, a fan is installed in the bathroom, which will cope with excess moisture in the room. The connection diagram for such a fan is simple, and you can install the hood in the bathroom yourself.

Household fans are divided into two types:

• axial;
• centrifugal.

Whichever type and model you choose, both of them are installed in the ventilation shaft on the ceiling or wall.

In most cases, axial devices are chosen for the bathroom. This mechanism is set up as follows. A propeller is installed on the axis with an electric motor. The engine drives the blades that suck in moist air and discharge it into the ventilation duct.

Axial bathroom fans are made of plastic and therefore light in weight. The installation of such an exhaust system is simple, and the connection diagram of the hood will be shown below. It is suitable for those bathrooms where aerodynamic drag is minimized.

In other cases, it is better to use a centrifugal fan. Such a fan is recommended to be placed in places where there are problems with ventilation. Such a mechanism is much larger in design than an axial fan. It has a housing that is visible from the outside, and a turbine with blades, which is designed to pull moist air out of the room.

More models for bathrooms are divided according to the principle of operation. There are such types:

• dependent on the light switch;
• switched off by the timer;
• independent.

Models dependent on a light switch only work when the light is on. But sometimes this period is not enough to get rid of excess moisture in the bath. They will also make unnecessary noise when their work is not needed at all, such as brushing their teeth. One of the options that can be recognized as a universal model is fans with a humidity sensor.

A fan with a humidity sensor allows you to set the operating time of the ventilation system

Models that are switched off by the timer, as already clear, are equipped with a timer for the hood. It sets the desired operating time of the ventilation system, so you can safely leave the bath knowing that at the right time the fan will turn off on its own.

Independent fans have their own switch, so they can be turned on and off at any time. Such hoods do not depend on other electrical appliances, and they can be set to a mode in which the fan turns off by itself.

Additional Fan Features

Today, the market for ventilation equipment provides a large selection of exhaust systems. Anyone, even the most fastidious buyer, will find a mechanism suitable for his bathroom. Moreover, hoods with a mass of additional functions are now available. These include:

Exhaust fan with clock allows you to control the time

1. Extraction timer. Thanks to him, the hood will work even after the light is turned off, you just need to set the timer for the right time.
2. Motion Sensor. This function will allow the fan to turn on at the moment when there is movement in the bathroom, and turn off after the time specified in the settings has elapsed.
3. Humidity sensor. If the fan has such a function, it will automatically turn on when the humidity level reaches a certain limit, and turn off when the humidity in the room reaches the desired level.
4. ventilation function. If the hood has such an opportunity, then the fan will periodically turn on at minimum speeds in order to provide fresh air to the room.
5. The presence of a clock on the dashboard. This feature will help if you are limited in time and do not want to be late somewhere. The clock on the hood will help you control the time you take a shower.
6. Moisture resistance. This feature is important if water gets on the fan.

How to choose the right bath hood

Before you buy a bathroom fan, read the criteria that will help you choose the most suitable model. Here are the parameters by which you should evaluate the hood for the bath:

1. Power. You need to know exactly how much space the fan can cover. Therefore, it is worth making the following calculations: the volume of the bathroom is multiplied by the amount of air replaced per hour. On average, the figure should be 100 cubic meters per hour.
2. Noise. The switched on hood makes noise, which should not be higher than 20-25 dB.
3. Safety in operation. This is important if the room in which the hood is located is likely to get moisture on it.

Therefore, when buying a fan, you should pay special attention to this.

If you are faced with the choice of which model to take a device, less noisy, or with more power, then make a choice in favor of performance, and you will not be mistaken.

Installing a ventilation system in the bathroom

If you have thoroughly studied the ventilation equipment market and purchased a bathroom hood model, then proceed to the process of connecting an exhaust fan. The connection diagram of the hood is simple, and if you follow the instructions, then installing a fan for the bathroom will not be difficult.

1. First of all, you should make sure that the wiring is connected to the ventilation shaft, otherwise the exhaust fan with a timer will not be connected to the mains. If the power cable is available and it is operational, then proceed to check the ventilation shaft, it should not contain debris and dirt. If, after inspecting the ventilation duct, elements were found that impede the outflow of air, then eliminate them, if it is not possible to do this on your own, then contact a specialized service. Now check the diameter of the ventilation shaft and the hood itself, they must match. If all these indicators are normal, then proceed with the installation of a fan with a timer. And if you have chosen an exhaust fan with a humidity sensor, then this will be an additional plus in the fight against moisture and dampness.
2. First, remove the decorative nozzle from the fan. Next, connect the cable to the hood. This process is simple, the main thing is not to confuse the phase and zero. Another important point. During installation of the fan in the bathroom, turn off the electricity in the apartment.
3. After the cable has been connected to the hood, it is installed in the ventilation duct. This is done with the help of self-tapping screws, which manufacturers sometimes put in a kit with a hood or sealant with glue. If you have tiles in your bathroom, then in this case it is recommended to use glue, otherwise there is a risk of damaging the tiles.
4. Before installing the decorative cover, check the work done and test the fan. If all the installation steps were carried out correctly, the hood will work properly. Now install the protective cover and you are done.

If you need a timer for the bathroom exhaust fan, and it was not included with the hood, then it can be purchased separately from the fan.

In the event that it is not possible to bring wiring into the ventilation shaft, then you should not be upset, there is also a way out of this situation. In such bathrooms, the fan is fed through a light bulb. A cable is thrown and one end is connected to the light bulb, and the other to the hood. So that the cable is not visible, it is hidden in a box. In this case, the fan will turn on with the light, and turn off in the same way.

As you can see, the bathroom fan connection diagram is very simple and does not require hiring a specialized team.

And if you are just designing your own home, then pay more attention to the bathroom ventilation system. It is best to install a window in the bathroom through which fresh air enters the room. And if the ventilation in the house is designed correctly, then there will be no place for dampness and fungus in it, and the air will be fresh.
