What to do if heating batteries are too hot

Often the air in radiators becomes the cause of the inoperability of the entire heating system in the house, so it is important to learn how to bleed it so that the heat comes into the apartment in a timely manner.

Air and heating

The heating system is based on the circulation of hot water through the pipes, when air enters them, the process is complicated. The result is:

1. Noises when moving water. They cause vibration of the pipes and weakening of the welds, which in the worst case can burst;
2. Air plugs that paralyze the heating system either locally or extensively;
3. Oxidized parts of pipes that corrode. Airing greatly reduces the life of radiators.

Where does the air come from

It seems surprising that air appears in a sealed system, moreover with enviable regularity. There are several reasons for this:

• Incorrect determination and determination of the slope of the pipes during the installation of heating;

• Incorrect filling of the heating system with water;
• Lack of tightness or its violation between the constituent elements of the system;
• Ignoring the installation of special devices that evacuate air;
• Repair work of radiators and heating systems;
• Fresh water in the system, enriched with a lot of air;
• Corrosion of metals from the inside.

What to do

If the heating system is closed with forced circulation, the installation of devices to help get rid of air will help. Their attachment points are the highest pipe points or kinks. Devices are manual and automatic. The first type includes a Maevsky crane, which is mounted on the side of the pipe. During the supply of heat and water, you just need to open the tap and bleed air. Automatic systems allow air-conditioning without human intervention.

Filling heating water

Pipes are filled in the heating season with cold water from the bottom up. All taps, except those that run on the drain, must be loosened. Water gradually squeezes out air, filling should not be carried out quickly. After the water passes through the tap, it is screwed. After full filling, the pump starts.

Air use

Often air jams form in the system used for many years. Usually their appearance coincides with the beginning of the heating season. You must be able to air the system on time in order to avoid emergency situations.

Sequencing:

• The place of the air plug is determined tactile (places with air are colder) or acoustically (water passes with noise);
• Searches for the closest Mayevsky crane;
• The tap opens and at the same time a fresh portion of water is poured into the system.
