On how well ventilation in a private house is properly thought out, the freshness of air in all rooms depends. However, excellent ventilation in the kitchen, in the bathroom and the bathroom is a rare phenomenon. Replacement of wooden window frames and door constructions with plastic and metal prevents natural air circulation. Therefore, you need to pay attention to the fact that the windows were equipped with supply valves. This will ensure an additional influx of fresh air. But there are many other nuances about which we will talk later. So, the topic of this article: an extract in the bathroom in a private house with your own hands - which option should you prefer?
to the contents ↑How does the intake and exhaust ventilation work?
The most effective ventilation system to date is a forced supply and exhaust system, with heat recovery. As a rule, it is used in those rooms where the air problems have the greatest problems - in the kitchen and in the bathrooms. The use of special equipment - extracts, makes it possible to remove the exhaust air.
Device
The ventilation unit is the main component of the system. It includes the following elements:
- Control unit.
- Filters.
- Fans.
- Heat exchanger-recuperator.
In addition to the ventilation unit, the system contains the following components:
- Exhaust air duct.
- Exhaust air thermostat.
- Deflector.
- Supply air anemostat.
- Air Intake.
Operating principle
Air is exhausted from the room to the deflector located on the roof through the exhaust air intake. The arrival of a fresh air jet occurs through the intake air intake, which is distributed through all the rooms through a unit of supply and exhaust ventilation.
to Contents ↑How does heat recovery work?
In the cold season, air jets( warm - retracted and cold - incoming) are found in the heat exchanger.
Important! Air jets do not mix. Warm air gives warmth to the cold coming from the street.
Recuperation gives the possibility to distribute heated air already in the premises of the house. Thus, the cost of heating the premises is reduced by about a quarter.
Important! Thanks to modern technologies, the ventilation unit is equipped with auxiliary means for humidifying and cleaning the supply air.
Advantages of such a system:
- An efficient heat exchanger allows you to save money on heating the premises.
- Providing all rooms of the house with warm air, regardless of the weather.
- Effective removal of the finest dust particles due to the filtration system.
- The possibility of changing the temperature and humidity of air coming from the street.
- Possibility to regulate the air exchange, based on personal preferences and desired indoor climate parameters.
Important! The system for diagnosing and evaluating the efficiency of the system allows you to identify malfunctions and signals the need to replace filters.
Are there any disadvantages?
The disadvantages of the forced ventilation system are:
- Additional power consumption by the fan and the control unit.
- In case of power failure, the ventilation system is turned off automatically.
- Technical complexity, and hence - the need for regular maintenance.
- High cost.
- Noise during operation.
Important! Installation of the system should preferably be entrusted to a highly qualified specialist, and this - additional costs.

If you neglect the arrangement of the hood in the bathroom, the moisture will begin to accumulate in the room, which leads to the development of mold and fungi. Thoughtful ventilation due to rapid air exchange will allow to forget about mold and unpleasant smells.
Important! For a bathroom the best option would be a wall fan on the sleeves, preferably without bearings. Unlike the design on bearings, they work not so noisy and have a low price.
A must-have accessory of the bathroom and toilet is the extractor. It is thanks to the installation of the hood in the private house that there is an active air exchange necessary to maintain a normal microclimate in the room.
Application of modern technologies allows to use ventilation systems more effectively. For example:
- motion sensor helps to turn the system on and off autonomously;The
- humidity sensor helps to maintain the optimum value of this indicator, including ventilation, when necessary.
Important! It is advisable to place the extractor switch in the bathroom itself. Automatic activation of ventilation is not always justified. For example, you can go to the bathroom to clean the room or brush your teeth.
With regard to the connection of the hood in the bathroom or toilet, the following options are possible:
- A switch installed inside the room( for independent control of the switching on and off of the ventilation system).
- Automatic activation of the hood with the inclusion of lighting and an additional switch. At the same time, the "machine" will work when it is really necessary.
Cooker hood in the private house
The kitchen is a room with high humidity. In addition, the air is polluted with the smells of food prepared, 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 as soon as possible with fresh and as soon as possible removed from the house.
- The volume of the kitchen should be correlated with the number of hotplates on the stove: 2 burners - 8 cubic meters, 12 cubic meters - no more than 3 burners. Four hotplates on the stove are permissible if the cubic capacity of the room is 15 or more.
- According to the normative documents, the air exchange rate is 140 cubic meters per hour for kitchens with gas stoves. For a kitchen equipped with an electric panel, a similar figure is 110 cubic meters per hour.
Forced ventilation in the kitchen assumes:
- Mounting of special equipment in the vent hole, which will artificially distill the air. It is easiest to install a hood that works from an electrical network and directs polluted air to the street.
- The height of the hood above the plate is 600-800 mm, but not higher. Otherwise, the device will not be able to cope with its tasks.
Important! A slightly more complicated variant is the arrangement of a supply and exhaust ventilation system that not only removes dirty air, but also contributes to the influx of fresh air. The kitchen is thus part of the ventilation system for the entire house. If necessary, such a system is easier to equip with heating and filtering devices. Of course, supply and exhaust ventilation is an expensive exercise, but by investing money in it only once, you will use it for a long time.
Types
Extract is located above the stove, and the natural channel - under the ceiling, from the side of the stove. There are such options for kitchen hoods:
- Suspended. Works on a circulating basis. This is an option for a small kitchen, since it can not cope with large volumes of air.
Important! A significant disadvantage is the need to replace a carbon or acrylic filter. The advantage is that there is no need to mount an additional duct.
- Built-in. The device is placed in a pendant locker. For installation, an additional air 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 rather aesthetic design. Can be used for any location of the plate.
Important! Most often, installation of the hood in the kitchen in a private house is done in a wall or roof.
Tips for installing kitchen hoods in a private home:
- Steel and aluminum hoods - durable and durable.
- It is necessary to change the filter in the hood at least once every six months.
- Too powerful a fan can cause plugging of the duct. So - unpleasant smells and water vapor rush into the next room.
- Ducts and ventilation ducts should be periodically cleaned of grease and soot.
- For a spacious( more than 15 square meters) kitchen area, it is desirable to provide 2 ventilation ducts: for drawing and for fresh air intake.
Important! The hoods often use corrugated tubes of circular cross-section. As for the connection of electricians, it is better to entrust this work to professionals.
In this article you have read the basic principles of the organization of hoods in the bathroom and kitchen in a private house. Next, you will have a thorough calculation, selection of materials and directly installation of the entire system. We hope, you will manage to do it qualitatively, because this will determine the overall microclimate in your home.
