During the operation of the batteries, it is often necessary to burst the excess air inside the radiator. Provided that the radiator began to heat up uneven, bouffaging or hissing came from it, which most likely air got inside. In order to avoid bringing heating systems, it is necessary to take prevention measures.
Causes of importance
Sources, due to which air may appear in the heating system, are diverse, here are some factors due to which the central system can happen to be treated:
- Depressurization. (Depressurization can occur when performing repair work).
- Leak.
- Wrong installation.
- Seasonal repair work.
The individual heating system is rarely delivered, as a rule, an error in design may be caused.
Signs and danger of air traffic jams
Signs of the appearance of air traffic jams can be: a significantly reduced air temperature in the house, uneven heating of the battery, the appearance of hissing and bugging sounds. Because of the accumulation of air, the battery works are violated, such problems may occur as damage to the battery due to the difference in temperatures, damage to the circulation pump, acceleration of corrosion.Crane Maevsky
Maevsky's crane is a specialized air booming device, open which is possible with the help of a specialized key. There is a crane on the end of the radiator.
Interesting fact: to prevent illegal water drainage, Maevsky crane was installed on the heating system.
There are several situations due to which air traffic can occur:
- Improving the upper long corners of the battery due to the slow filling of the empty system.
- Air traveling in the coolant together with water starts to accumulate in favorable places for this. Such as the upper deaf areas of the radiator.
The design of this device is quite simple. The device consists of a brass housing, a working screw with streams, a nylon cap and a sealing ring, designed to provide tightness when mounting. The life of this device is about 30 years.
Maevsky crane varieties:
- Manual
This is one of the most popular modifications having a reliable mechanism. It is necessary that the crane is conveniently located, otherwise it cannot be unscrewed.
- Auto
This device is able to work in automatic mode, without the participation of a person, which is a huge advantage.
- With built-in fuse
This is an improved version of the manual crane with a high-pressure sensor. The operation of this device is to prevent the coolant malfunction, provided that the pressure in the heating system will exceed the mark.
Tip: Automatic crane is great for private houses that support the purity of the radiator well, and this kind is better installed in hard-to-reach places.
How to put air from the battery of heating?
First, you need to weaken the screw. Then, it is required to insert the tip of the key into the deepening on the crane of Maevsky. Rotate counterclockwise. To completely unscrew the screw is no need. There are 1-2 turns. No need to make too much effort, it is not possible to damage the valve. Next, give air to exit. After the screw will weaken, hearing hiss and there will be some amount of water.

Tip: The position of the air opening can be adjusted - so that the water does not spray the wall, it is worth lowering it down.
After the uniform stream of water is pioneering, and the hiss stops, it is necessary to spin the screw.
Automatic air vent
Automatic air vent is designed to output the air from the radiator. But this device has a significant drawback: it is susceptible to the quality of water. Therefore, you will have to resort to the help of filters. In addition, from time to time it is necessary to change the sealing ring and the needle of the valve. Otherwise, leakage may appear. The service life of the automatic air vent is about 35 years old.
Types of air vent:
- Straight. This species releases excess air upwards, and is connected from the bottom.
- Corner. It has an angular connection, air release is made up, calculated for installation in hard-to-reach places.
- Radiator. Connects from below, and releases the air to the side.
Methods of prevention
At the beginning of the heating season, it is necessary to keep the accumulated air from the battery, in winter it is to control the pressure in the radiator, whether the pipes do not proceed, track the consumption of the heating device. Observing these simple rules, you can prevent battery mappings.
How to wash heating batteries
There are several methods, how to quickly wash the radiators. These are such ways as dry and wet cleaning.
Dry cleaning
Dry cleaning is the removal of dust, web and crumbs with a dry cloth or vacuum cleaner. This method must be made once a year.Wet cleaning
Wet cleaning should be carried out at least once every 2 years. It contributes to the removal of fatty and appeared spots. But in advance it is necessary to produce dry cleaning. Then you need to determine the degree of contamination to understand what means must be used.
Useful tips How to wash the batteries:
- Before washing a cast-iron or aluminum battery, you need to remove the protective layer if it is available.
- When the heating is disconnected, it is possible to remove the radiator and wash it in the bath, but it is necessary to be causing a dense cloth to avoid damage to the enamel, it is also possible to add detergents.
- It is worth it to be sealed with water-repellent material wallpaper and parquet when wet cleaning.
- It is necessary to wear rubber gloves when using household chemicals or when cleaning the cast-iron battery, so as not to damage your hands.
- You can use acrylic paint with an extremely unattractive appearance of the battery.

Household devices for washing radiator
Many housewives care how to wash the radiator from dirt, what kind of sweater means to use. The following household appliances can be used for washing the battery:
- Hairdryer. He fades dust well.
Tip: So that the dust does not fly around the room, you can hang the moistened tissue material from behind the radiator.
- A vacuum cleaner. A very useful device in everyday life, but few knows that it can be used for washing batteries.
- Steam cleaner. Many housewives dream of this device, but it is necessary to be very careful when using it, in order to avoid burning burns.
- Electric kettle. If you pour a pig-iron battery with boiling water, then most of the garbage will be cleaned. But under the radiator it is necessary to put the pallet in order not to fill the floor.
Battery wash brushes and sponges
You also need to choose brushes and sponges to effectively remove contaminants. For cleaning batteries from dirt and dust it is necessary: Toothbrush capable of getting into the most hard-to-reach places; sponge; A brush for washing the dishes and a spray gun, with which you can wash away the contamination, pour into it a detergent and spraying it, after some time wipe wet rag.
Battery washing detergents
Provided that ordinary water cannot cope with pollution, you will have to use special means. Before using household chemicals, it is necessary to familiarize themselves with the composition, if there is aggressive substances that contribute to the destruction of the radiator surface, this tool is not recommended. List of means capable of help when removing contaminants:
- Lemon acid . For cooking, it is necessary to dilute in half the liter of water of 6 teaspoons of powder. This solution removes dirt, dust and unpleasant odor.
- Soda. To prepare a solution, you need to mix 1l water with 1 tablespoon of soda.
- Household chemicals for plumbing.
- Hydrogen peroxide 3% . For cooking, it is required to dilute 1 liter of water half the bottle.
- Washing powder . You need to mix it with water and wash with this solution with a battery. Then rinse thoroughly with water.
Important! It is necessary to close the respiratory tract if household chemicals with a sharp smell apply when washing the radiator.
What do you need to wash the batteries
Batteries are quickly covered with dust, which negatively affects the body's respiratory system. Fat stains are formed on radiators, if you do not wash the batteries for a long time, which subsequently can cause corrosion and violation in the operation of the radiator.
How the room is heated by the radiator of central heating
Central heating is the main complex that provides the necessary temperature in the rooms.

Radiators tend to have a sectional device. The design of sections consisting of a hollow vessel, inside which moves the coolant.
Battery depending on the material from which they are made are:
- Cast iron.
- Aluminum.
- Steel.
- Consisting of bimetallic alloy, namely from aluminum alloy and steel.
They have distinctive physical characteristics, the coefficient of heat transfer is considered one of the main indicators of these materials.
The heat carrier moves in the inner parts of the battery, the walls of which are heated, the external surface of the radiator gives the heat room. This is the basic principle of the heating system.
There are several components of heat recoil methods:
- Radiant - thermal radiation
The radiant heat exchange is a heat transfer using heating located around things, also calls it thermal radiation. When heated, the items transmit heat air.
- Convective - heating air flows.
Promotes heat transfer by heating of circulating air. The convective movement of air is based on the difference of densities - the cold air tends to be closer to the floor, and the heated invariably is at the top.
Heating systems are usually installed in places with the greatest heat loss, mainly under the windows.
To improve the quality of heat exchange, the surface of the battery is equipped with plates of fins. These plates contribute to an increase in heat transfer area and improve efficiency during battery operation. The change in the temperature of the heating system occurs with the help of shut-off-regulating reinforcement.
The heating radiator is considered the most popular view of the heating system in residential buildings. They perfectly perform the task of heat heat in the rooms and to maintain comfortable conditions for living.
Mass of the section of the cast iron heating system
The mass of the pig-iron battery sections is ~ 7.5 kilograms. Accordingly, the weight:
- 2-section battery equals 15 kg;
- 3-section battery equals 22.5 kg;
- 4-section battery equals 30 kg;
