What would happen if the heating radiators did not bleed in a house? Avoid problems, here we explain how to do it correctly
With the arrival of autumn and falling temperatures, it is necessary to prepare and fine-tune the heating system. If we have hot water radiators, it is necessary to purge them to check that they are in perfect condition after several months without use.
What happens if the radiators don’t bleed?
The bleeding of the radiators will prevent air pockets in the radiator pipes and tubes and, therefore, causing noise or energy waste, because in a non-bleeding installation the upper part will be hotter than the lower one. They can also cause the gas boiler to lose pressure and therefore not work properly.
Purging process of water radiators
The way to bleed the radiators is relatively simple. First, we will need a bucket or water container to collect small leaks of water and a screwdriver to turn the radiator valve or a screwdriver if it is a screw. In addition, we must make sure that the heating is turned on and that the radiator’s hot water tap is open.
We will place the container under the screw that opens the radiator valve. We are going to slightly open the valve with the screwdriver and let the air out until only water comes out. Then we close the valve and proceed to bleed the next radiator.
It is important to start from the nearest heating radiator to the furthest. In this way, we will get the radiator to heat up perfectly and therefore save on heating.
At the end of the process, we will check if the radiator has the same temperature at the top and at the bottom, as well as the boiler pressure at 1 bar.
