Hood in the bathroom in a private house do-it-yourself

On how well ventilation in a private house is thought out, the freshness of air in all rooms depends. However, excellent ventilation in the kitchen, in the bathroom and in the bathroom is a rare occurrence. Replacing wooden window frames and door structures with plastic and metal prevents natural air circulation. Therefore, you need to pay attention to the fact that the windows are equipped with supply valves. This will provide additional fresh air. But there are many other nuances, which will be discussed further. So, the topic of this article: an extract in the bathroom in a private house with your own hands - which option should I prefer?

How does the supply and exhaust ventilation work?

The most efficient ventilation system to date is a forced air supply and exhaust system, with heat recovery. As a rule, it is used in those rooms where the greatest problems arise with air exchange - in the kitchen and in bathrooms. The use of special equipment - hoods, makes it possible to remove exhaust air.

Device

The ventilation unit is the main component of the system. It includes such elements:

• Control block.
• Filters
• Fans
• Heat exchanger recuperator.

In addition to the ventilation unit, the system contains the following components:

1. Exhaust duct.
2. Exhaust anemostat.
3. Deflector.
4. Supply anemostat.
5. Air intake

Operating principle

Through the exhaust air intake, air is discharged from the room to the deflector located on the roof. The arrival of a fresh air stream occurs through the supply air intake, which, through the supply and exhaust ventilation unit, is distributed to all rooms.

How does heat recovery work?

In the cold season, air jets (warm - exhaust and cold - incoming) are found in the heat exchanger.

Important! Air jets do not mix. Warm air gives off heat to the cold coming from the street.

Recuperation makes it possible to distribute already heated air throughout the house. Thus, heating costs are reduced by about a quarter.

Important! Thanks to modern technologies, the ventilation unit is equipped with auxiliary means for humidification and purification of the supplied air.

The advantages of such a system:

• An efficient heat exchanger saves money on space heating.
• Providing all rooms of the house with warm air, regardless of the weather.
• Effective removal of the smallest dust particles due to the filtration system.
• The ability to change the temperature and humidity of the air coming from the street.
• The ability to control air exchange, based on personal preferences and the desired indoor climate.

Important! The system of diagnostics and assessment of the system performance allows to identify malfunctions and signals the need to replace filters.

Are there any disadvantages?

The disadvantages of a forced ventilation system include:

• Additional power consumption of the fan and control unit.
• In the event of a power outage, the ventilation system shuts off automatically.
• Technical complexity, and hence the need for regular maintenance.
• High price.
• Noise during work.

Important! It is advisable to entrust the installation of the system to a highly qualified specialist, and this is an additional cost.

Hood in the bathroom do-it-yourself

If you neglect the arrangement of the hood in the bathroom, then moisture will begin to accumulate in the room, which leads to the development of mold and fungi. Thoughtful ventilation due to quick air exchange will forget about mold and unpleasant odors.

Important! For the bathroom, the best option would be a wall mounted fan on the bushings, preferably without bearings. Unlike the design on bearings, they work not so noisy and have a low price.

A mandatory accessory for the bathroom and toilet is a hood. It is thanks to the installation of the hood in a private house that active air exchange is necessary to maintain a normal microclimate in the room.

The use of modern technology allows the use of ventilation systems more efficiently. For example:

• motion sensor helps turn the system on and off autonomously;
• a humidity sensor helps maintain this value, including ventilation when necessary.

Important! It is advisable to place the hood switch in the bathroom itself. Automatic inclusion of ventilation is not always justified. For example, you can go into the bathroom to clean the room or brush your teeth.

As for connecting the hood in the bathroom or toilet, the following options are possible:

• Indoor switch (for independent control of turning the ventilation system on and off).
• Automatic activation of the hood with the inclusion of lighting and an additional switch. In this case, the “machine” will work when it is really necessary.

Hood in the kitchen in a private house

The kitchen is a room with high humidity. In addition, the air is polluted by the smells of cooked food, particles of carbon monoxide. For this reason, good ventilation in the kitchen is an objective necessity.

The requirements are as follows:

• Ventilation should be such that the exhaust air is diluted with fresh as soon as possible and removed as soon as possible outside the house.
• The volume of the kitchen should be related to the number of rings on the stove: 2 rings - 8 cubic meters, 12 cubic meters - no more than 3 rings. Four rings on the stove are permissible if the cubic capacity of the room is 15 or more.
• According to regulatory documents, the air exchange rate for kitchens with gas stoves is 140 cubic meters per hour. For a kitchen equipped with an electric panel, a similar figure is 110 cubic meters per hour.

Forced ventilation in the kitchen involves:

• Installation of special equipment in the opening of the ventilation pipe, which will artificially distill the air. The easiest way is to install a hood that works from the mains and directs polluted air to the street.
• The height of the hood above the stove is 600-800 mm, but not higher. Otherwise, the device will not be able to cope with its tasks.

Important! A slightly more complicated option is the arrangement of the supply and exhaust ventilation system, which not only removes dirty air, but also simultaneously contributes to the influx of fresh. The kitchen, therefore, is part of the ventilation system for the entire house. If necessary, it is easier to equip such a system with heating and filtering devices. Of course, the supply and exhaust ventilation is an expensive undertaking, but having invested money in it only once, you will use it for a long time.

Kinds

The hood is located above the stove, and the natural channel is under the ceiling, from the side of the stove. There are such options for cooker hoods:

• Hanging. It works according to the circulation principle. This is an option for a small kitchen, as it cannot cope with large volumes of air.

Important! A significant minus is the need to replace a carbon or acrylic filter. The advantage is that there is no need to install an additional duct.

• Recessed. The device is located in a hanging cabinet. For installation, an additional duct is required, which can be brought into the finished ventilation system.
• Dome. This is the most effective and powerful option. Modern models have a fairly aesthetic design. Can be used in any location of the plate.

Important! Most often, the hood is installed in the kitchen in a private house in the wall or roof.

Tips for installing a kitchen hood in a private house:

• Steel and aluminum hoods are strong and durable.
• It is necessary to change the filter in the hood at least once every six months.
• Too powerful a fan can cause clogging of the duct. So - unpleasant odors and water vapor rush into the next room.
• Ducts and ventilation ducts must be periodically cleaned of greasy deposits and soot.
• For a spacious (more than 15 square meters) kitchen room, it is advisable to provide 2 ventilation ducts: for extracting and for receiving fresh air.

Important! Hoods often use round corrugated pipes. As for connecting electricians, it is better to entrust this work to professionals.
