order to flush air from the radiator heating, must first read the instruction Trapped air in the heating system, it is a major obstacle to its proper functioning. With this question, residents of apartments and houses are dealing, as a rule, in the fall, at the beginning of the heating season. Whistling and noise in batteries, a cold riser and radiators, corrosion of metal elements - all this leads to the formation of air plugs. This happens even with a well-designed and installed heating system.

Why are cold battery: the air pull out
radiator for reasons of air into the seemingly looped heating system, there may be several, but the result is - cold radiators. That is why many residents of apartment buildings and freeze in the winter in a cold apartment or a private house.
The radiators are also smothered by the draining of water from the pipes for the summer, which is so popular for employees of district heating services.
Poorly connected joints of pipelines, which are also present in central heating systems, give not only a leakage of water. Through them, the system sucks in air.
If the batteries are a lot of air, in which case they will not be heated
Causes of air into the tube:
- End repair system( assembly, cleaning, blowing, pumping, demolition of the pipeline);
- Incorrect installation of a new heating system;
- Malfunction of air intake systems;
- Low pressure in water pipes;
- Connection of the system of water "warm floor", the pipes of which are located at different heights;
- Incorrect filling of the heating system.
The latter factor most often causes the air to enter the looped system. There are special rules according to which it is necessary to drain and pour water into the pipes, but, sometimes, unscrupulous employees do not observe them, and voids form in the pipes.
Consider how to remove the air plug from the heating system
If cold bimetal radiators are observed in homes, then it is necessary to remove air from the heating system. This operation can be carried out in various ways.
Before discharge air, it is necessary to determine the method of air circulation in the coolant
Selectable method depends on the mode of circulation of the coolant. It can be: natural, or forced.
- In a system with natural circulation of water, appeared airlock may be removed with the help of the expansion tank, which is located at the top.
- With bottom wiring, air purge is usually performed in a manner similar to air removal in systems with a circulation pump;
- You can deactivate or purge air from a heating system with natural circulation by using the expansion tank;
- Heating systems using a pump, at the highest point the air collector is specially installed, designed for the descent or discharge of accumulated air.
In the latter case, the supply pipe must be installed correctly. In this case, ascending the clump of air, are removed through a special auto-shutter. In all methods, the return pipeline must be laid with a slope in the direction of draining the water. So, if you need to repair heating, get rid of water can be most quickly.
bleed screw, vent how to pull air from the heating system
air vent are manual and automatic. Hand-held air vent devices, or Maevsky air-separator, are small in appearance. Usually they are installed on the front of the battery. Adjust the tap-razvozvoshivatl Mayvsky using a conventional wrench, a screwdriver, and some even manually.
By itself, the Mayevsky graduate is small, and its performance is relatively small. In view of this, its installation is applied only to eliminate small air plugs in a separate heating system. In the water pipe, this tap is practically not used.
A second type of instrument capable of draining or purging air is automatic devices that operate without human intervention.
quickly and easily release the air from the heating system can be by means of special air vent, which may be either manual or automatic
Properties Air vent:
- Have a high efficiency in the operation, however, a very sensitiveTo contaminated water;
- They are usually mounted together with filters;
- The airgun is usually installed in closed-type heating systems using a gas boiler at different points;
- Air discharge from each device is done separately;
- An efficient multi-stage air-handling system, which successfully pushes plugs, is considered to be the most effective.
With proper piping and installation of pipes, the air through this device will be easy and not problematic. According to customers of the site Tovago, crane-razvozdushivatel Maevskogo today is very popular.
How to let the air out
battery usually that the system zavozdushena indicate other sounds such as gurgling, hissing water flow. Air bleeding in these cases is simply necessary.
In order for the water to circulate freely through the system, it is necessary to remove this air and carefully pump the system.
After deflation should be properly bled
If zavodushivanie system strong, you first need to identify the place of air congestion. It is determined by tapping the hammer on the heating system. In a place where there is an air cork, you will hear a more sonorous and strong sound. Air is collected, usually in radiators, which are installed on the upper floors.
What if airy system:
- Take the key or screwdriver, and prepare a container under the water;
- After opening the thermostat for the whole, open the valve of the Maevsky crane, and replace the container;
- Keep the valve open until water flows from it;
- After receiving a clear flow of water from the tap, it is closed.
happens that after cleaning the radiator heating system heats the apartment house for long or weak. Then it is necessary to purge and rinse, since the accumulated debris and rust make the congestion, and can also cause the formation of air congestion. If after this procedure there are no improvements, then it is necessary to check the water level in the heating system. Air jams are constantly formed at the bends of pipelines. In view of this, during the installation it is important to observe the direction and degree of slopes of the distributing pipelines. Where the deviation differs from the design, an airship must be additionally installed, from where it will be possible to release air. The most intense air plugs are formed in aluminum radiators. This is mainly due to poor material quality. To ensure that the heating of the apartment was normal, it is necessary before the system is filled with water, to release air from it in a timely manner, which interferes with the normal movement of the coolant. That is why, many tenants of apartment buildings and can not drive the cold out of the apartments.
Heating air: the causes of the formation of the plugs
The problem of removing the formed air congestion from the heating system is very relevant at the moment, since almost all people face this problem, at least once in their life. In the absence of Mayevsky cranes in radiators, sometimes air can be vented using the method of unscrewing a cap on the radiator in which air is accumulated. This method of etching air is very dangerous, since in the case of an inadvertent, or very strong unscrewing of the plug, it can break down. This will entail a flood in the room. And since the heating system is provided with a lot of pressure in the system, the elimination of the problem can drag on for a long time, and not one apartment will suffer, but several. And pumped air does not help you get rid of problems.
Basically, the airing of the system is the result of errors in the design of heating, or after a partial replacement.
Often, the violation of the central heating system has a different origin. Sometimes heating radiators can be filled with air plugs due to physical deterioration of the heating system elements.
In the heating system, air plugs can be accumulated which must be lowered in time
What you need to ensure that the system does not accumulate air plugs:
- Make sure that the heating system is in a normal, Technical condition, and is able to pass water;
- Specify when exactly the heating system was replaced in your area, it may be necessary to overhaul the heating main;
- The central heating system of a residential building can only be commissioned by specialists, and in accordance with the installation rules.
- When installing individual heating, it is absolutely necessary to observe the general requirements for this type of heating circuit.
- When filling the water in the system, it is necessary at the same time to gradually remove air from it.
- to timely remove air from the system, in its upper point or towel warmer at the top, it is recommended to set the automatic air vent.
The nuances of operation depend on the types and characteristics of the individual heating system. Usually, with proper design and competent installation of the system, the water circulates correctly, and is not airborne.
Learning how purged heating system: coolant recovery operation
methods of air removal from the system depends on how precisely the coolant circulating therein. In the case where water flows through pipes in a natural way, the air plug is removed through the expansion tank located at the top of the system. With the so-called top wiring, the pipeline that feeds water comes to the expander at a certain angle. In the case where the wiring is lower, the accumulated air is discharged in the same way as the forced circulation of the coolant.
With forced circulation of water, the system provides an air tank, usually located at the top, and is responsible for the discharge of air pressure. The supply pipeline is located with a rise in the direction of movement of the water, and the air in it is accumulated in the air inlets and must be removed through special air vents.
If the system is closed, the data is replaced with air intakes on the automatic air vent, which are installed at several locations of the heating system. Through them, the air is discharged separately.
acquainted with how purged heating system, you can own, studying in detail the step by step instructions
How purged the entire heating system:
- determine the place where supposedly going to air. This can be determined by the noise in the pipes and radiators. The air-struck places are colder.
- Find a point located above the movement of the coolant, in which there is the presence of air vent Majewski, through which air can be released.
- Switch on the whole system and bleed the air.
This is a universal standard set of actions that allows you to not have to worry about how to eliminate the airing of the entire heating system and clean the pipe from the air alone.

In order to increase the indoor air temperature in winter, we resort to a variety of methods. Even we warm water in the boiler. Although sometimes the issue is solved by simply fanning the heating system.
