Air in a heating radiator is a problem that prevents the system from working efficiently. The fact is that the battery in this case cannot be completely heated. An air cushion prevents the spread of water throughout the radiator. Naturally, the issue needs to be addressed immediately. Otherwise, you will pay money for low-quality heating and freeze, wrapped in a plaid.
The cause of this problem is the repair or preparation of the system for the season, improper filling of pipes with water, poor tightness of the elements, the presence of air in the liquid itself. If the radiator heats up very poorly, then you need to learn the information on how to bleed air from the batteries. In principle, the procedure is not difficult, so you can do it yourself. Naturally, all actions must be done very carefully so as not to break the radiators.
First of all, you must make sure that your system is equipped with special air vents with valves on which the faucets are installed. Before bleeding the batteries, decide if you need any tools for the job. In principle, they are only required for manual air vents. In this case, for the procedure you will need a simple key or a screwdriver. With automatic descent systems, things are much simpler. However, they are very sensitive to dirt.
Before blowing air out of the batteries, try gently tapping them with a hammer. If you hear a very loud sound, then there is a traffic jam in this place. Now you can begin to bleed air. Since water will begin to drip after it leaves the pipe, you will also need a towel or a small container to collect it. Now take a key or other tool and open the valve. At this time, you should listen to the sounds that will be heard from the battery. The air should come out with a whistle or hiss.
Since bleeding air from the batteries is quite simple, one should not forget about accuracy. After the cork leaves, water will ooze from the radiator. This indicates that there is no more air in the system and the valve can be closed. Do this carefully so as not to break anything. Otherwise, you cannot close the battery, and you will have to call the repairman.
If, after carrying out these works, the heating does not work efficiently enough, then you will have to rinse or blow out the batteries. If this procedure also did not help, then the system is not well filled with water. You should also take into account the fact that the air plug comes out faster if the fluid in the radiator is hot.
It should be noted that it is rather difficult to remove the problem from batteries made of aluminum. Therefore, try to bleed air regularly, even if the system heats well. If the heating is autonomous, then to fight the cork sometimes you have to flush the water through the expansion tank.
Now you know how to bleed air from a radiator with your own hand. Let your home be warm and comfortable during the winter cold. Good luck
