Supply valves in the wall: prices, installation. Supply air vent

The need to create special channels until recently was completely absent. The function of natural ventilation was provided by defects in the house in the form of cracks, large gaps and bridges of cold. However, with the improvement of construction technologies, the walls and finishes became more sealed, which necessitated the introduction of special systems for air exchange. To date, supply valves in the wall are the simplest means of ventilation, which is implemented artificially. The effectiveness of such installations depends on many factors, including installation, climatic conditions of the terrain and configuration of the location of the system.

Types of inlet valves

Inflow valves are available on the market in two main versions. These are models with constant ventilation, and options with the possibility of adjustment. In the first case, the owner receives a device that provides the same parameters and volumes of air exchange. In a pinch, the permanent supply valves in the wall can be completely closed for the time of departure. Usually such a choice is made because of atmospheric conditions, when the pressure drops outside and indoors are very different. Models with the ability to adjust more technologically, more functionally and more profitable from the point of view of ergonomics. Special management of such devices is due not only to the interests of ease of operation, but also to more productive operation of the system. These are valves in which the throughput is adjustable - the user can adjust the intensity of the airflow depending on the conditions.

In which rooms to install?

In the selection of valves should be guided by the needs of specific premises. It is important to take into account that air masses from living rooms are inflow to the toilet, bathroom and kitchen, as they are removed with the help of the ventilation channels located there . Taking into account the capacity of the supply valves, the number and location of the installation are determined. There are two approaches to determining the number of valves for installation in the house. According to a simplified scheme, the inlet valves in the wall must be installed in each room. A more economical configuration involves calculating the needs of a house or apartment in the open air - further, in accordance with these indicators, the capacity for each room is determined. Most of the difficulties in the planning process is caused by the kitchen, as there are certain limitations when combining valves and household appliances. For example, if there is a gas stove in the room, then a model with adjustable capacity should be used. If the kitchen is provided with a boiler or stove, then a model with a permanently operating valve is recommended for safety reasons.

Identify installation points

It is desirable to install the valves at a level of 2 m from the floor surface. This arrangement is most rational in terms of the comfort of the tenants. In addition, if the room is heated, then the air at this level will be warm enough. In winter, this approach will also help to get rid of drafts. The installation itself can be performed in the upper window part or in the doorways. However, experts recommend the installation of supply valves in the wall, since this method will ensure reliable fixation of the device and will not cause any special problems with dismantling. For comparison, if you install the valve in a door or window box, you will inevitably have to revise the design of the system's media, and this will entail additional costs.

Installation technique

During the installation, a special hole is made for the valve, after which the free niches are sealed, and a protective visor is introduced. Also, the installation of a supply valve in the wall can be carried out in combination with a special profile. In this case, the device will be integrated into the protective case, which will facilitate the fixing process. But there is a minus in similar solutions - they will occupy more space in the wall and will require the creation of a hole of a larger diameter.

In general, wall valves are recommended to be installed during the construction phase, as in the finished house this event will cause much more trouble. As an alternative solution, you can also provide for installation through special openings, but in this case, you can lose the warranty. In addition, the installation of a supply valve in the wall can be carried out either in a living room or in the kitchen. Due to humidity, such installation is not allowed in the bathroom.

Methods for regulating valves

It has already been noted that some types of valves allow you to adjust the parameters of their operation. In particular, there are systems with automatic and manual regulation of volumes of supplied air, degree of filtration and even humidity level. Models with manual tuning are usually equipped with a special leaf, in which the position changes and, accordingly, the capacity is adjusted. If it is planned to install a supply air vent valve into the wall without the user's intervention in its adjustment, automatic models should be purchased. Such devices independently control the throughput depending on the pressure, the humidity level of the air and the temperature from the outside.

Price issue

In the simplest versions, the ventilation valves are inexpensive. Only for 500-700 rubles. You can buy a good model from a well-known manufacturer. However, if you need several devices with installation for a long time, it is better not to save and purchase more technologically and reliable supply valves to the wall, the price of which will be about 2-3 thousand rubles. It can be hygro-controlled devices that react to changes in humidity values and independently change operating parameters. The most expensive models include a sensor made of a polyamide tape that controls the flaps, increasing or reducing the flow of air. Also, the installation costs that can be quite impressive when installing the valve in the wall should be considered. As a rule, specialists mount devices purchased at their own companies with significant discounts, but still the cost of this part can be 1-2 thousand rubles.

Feedback on the effectiveness of the valve

Despite the simple design and extensive management capabilities of such systems, they are not widely used. Nevertheless, there are many consumers who use such valves in private homes. They just leave positive feedback on the performance that the homeowner who installed the intake valves to the wall receives. Criticism of this approach to ventilation is based on two points. First, with a similar function, complete air conditioning systems are being managed. Secondly, interference in the wall for the sake of such a minor adaptation does not justify itself - again, with a similar trouble you can introduce a more functional system.

For which houses is the supply valve suitable?

Either way, and a small valve with ventilation can be useful. It is advisable to use it in houses that are operated in conditions of sharp temperature changes, but do not require the provision of large volumes of air exchange. It is important to understand that the supply ventilation valve in the wall is mostly a filling element of natural ventilation. That is, one should not expect high efficiency from it, but one can expect to correct the microclimate.

Conclusion

The market offers different models of air-supply systems, so judging the very principle of their work with only one design is not worth it. Even within the family, there are quite different possibilities for the system. For example, if you integrate the supply and exhaust valve into the wall with the possibility of automatically adjusting the operating parameters, this will ensure maximum ventilation function without the use of overall equipment. A compact device, neatly embedded in the wall, will not spoil the facade of the building, but it will provide autonomous control of the air environment inside the premises. With regard to costs, they are minimal compared to special climate equipment, so you can count on the economics of such ventilation.
