Do not bask in the batteries ?It can be fixed


  • 1 air in the apartment
  • 2 air in a private house
  • 3 Methods for removing air

Before the start of the heating season is often a problem zavozdushennosti system.This leads to partial or complete blocking of heating circuits for coolant leaks on them.As a consequence, do not heat the battery.Also, this problem is often found in apartment buildings built on old projects.They are usually not set at all, and does not provide for automatic air.And then the question arises: "How to pull air from the battery in an apartment building?" Usually, when you turn on the central heating system utilities workers independently bypass all the apartments in these homes and the air is lowered.But if it does not, you probably forgot about you.And then you must take the matter into their own hands.Call in housing or own bled.

air in the apartment

so as to let the air out of the battery in the apartment?If your apartment is cold, even below the neighbors do not know where to hide from the heat.It

is likely you have there is air in the heating batteries.In order to pull it, you need to open specifically for this valve.It is usually found at the top of the Con in homes with radiators, built-in wall.To access it you will need a special key, which can be made independently.In new houses radiators are inside the apartment and on them are the so-called Majewski cranes.It is a nut and bolt in the middle.Bolt has a conical shape and closes the air vents.

must be remembered that in apartment buildings the pressure is very high, so much the union can not twist.All actions are performed slowly and carefully as possible.

in a private home is much easier, because the heating system is autonomous.If necessary, it is always possible to turn off.Especially that for effective removal of air in the system is just recommended.Air pocket in the radiator in a private home may be for two reasons:

  1. Poorly venting after the last repair.After carrying out all kinds of repairs to the heating system it is necessary to produce each of the radiator of his descent.But if the cork is far enough away from the valve, it is possible to simply wait for its release.
  2. Chemical processes in the radiators, and zavozdushennost - a gas formation.When poor-quality radiator castings with a variety of shells not only lost the strength of the radiator, but also reduces the efficiency of its heat.

Methods for removing air

Depending on the type of heating system can be identified and several ways to get rid of the air in the batteries:

bleed screw

  • In a system with natural circulation.In this case, to remove the air in the expansion tank can be used batteries.It must be installed at the highest point of the house, and it has an air valve - nipple.For greater effectiveness of the system is recommended to heat well.When heated air as a vapor begins to rapidly rise up, thereby necessarily fall into the tank.
  • special air vent can be installed in case of forced circulation.They are also installed in high points for the same reasons.When using such systems on their own to lower the air is not required.Unfortunately, this in theory, because in practice these devices only operate well in the floor heating system, when the distribution manifold to be low.Automatic nipple is located on the far end of the entrance.

In carrying out venting of batteries in a system with forced circulation boiler or recommended to disable the boiler.Because when the valve is opened due to a sufficiently high pressure (0.8-1.5 atmosphere), air can enter into it even more, and it may be in other radiators.

To bleed air from the battery is necessary to open the valve, usually installed valve Majewski, and under his removal to substitute a small container.There in the air vent will flow and water.Today there are various types of valves and even universal.To open them you need to be in possession of an ordinary flat screwdriver or a special 4-sided key.It is sold freely, and there is a complete radiator.Recommended merging not less than 200 g of water, it will leave the air around which could get into the radiator.After prevention system pressure drops and should be raised to the desired level.When using the brand Ariston boiler required pressure from 1.5 to 2 atmospheres.It is enough to heat the cottage.
