With the arrival of autumn and the first days of temperature drops, the houses begin to cool down. The normal thing is that they begin to make use of the heaters on colder days, but first of all it is recommended to make a verification of the state of the radiators and if they are prepared to operate at full capacity during the winter.

Bleeding the radiators is an option to think about before the cold temperatures hit and the radiators start working. The OCU points out that the first indications that a purge needs to be done are in the noises of gurgling produced by the appliances, as well as that one area is hotter than another. In particular if the upper part is colder than the lower part, since the air tends to rise.

In the event that it is needed purge it It must be taken into account that this action must be carried out with the heating off and cold. Therefore, the water stopcock to the radiator must be closed.

Then you will have to take a wrench or a screwdriver to turn the valve on the top of the device. This must be left open so that the water comes out constantly and without gurgling. This process will have to be repeated in each of the radiators in the house.

When the purge is finished, a checking the water pressure, which must be between 1 and 1.5 bars. The pressure gauge is usually at the bottom of the boiler.

In the event that the radiators do not heat or do it irregularly, the system may not be balanced. At the bottom there is another tap, the one that comes out of the circuit, the holder. To identify it, pay attention to the metal or plastic cover that hides an Allen screw, which opens the passage of water.

The function is precisely to compensate the water flow between the radiators of the system. When the boiler is in operation and the inlet valves and stoppers are fully open, it will be possible to check which ones heat up earlier and at a higher temperature.

In those areas that are needed, the inside can be closed a little more to divert the flow of the system to the radiators that need more temperature.
