If we want to keep our apartment warm in autumn and winter, we must be sure that the radiators are working properly. Strange sounds we hear from our radiators may be a cause for concern. Fortunately, we can easily deal with this problem. Check what you need to do.
Sometimes we may hear that our radiators make a characteristic gurgling noise. Combined with uneven heating of the radiator, it may this may be a sign of the presence of air in the installation. This happens when water cannot flow easily through the radiator, leaving part of its surface cold.
Typically, air enters the system when filling the installation through leaky mounting elements. So this means that we need to perform bleeding, which will allow us to get rid of the problem.
Fortunately, it is not complicated and does not require the use of many tools. We will need a bleeding key or a flat screwdriver, as well as a bowl and a cloth. Thanks to these things, we will improve the condition of our radiators completely in just a moment
When venting a classic radiator, we must know how to do it so that the process brings the desired results. We must begin our actions from closing the radiator valve.
Then we place a bowl under the vent and carefully unscrew the vent valve. If you hear hissing, it means that the air is leaving the system. After a while, water should start flowing. This will mean that the radiator has already been bled. Then this turn off the valve and turn on the radiator. As you can see, it is a simple process that will only take a few minutes.

It is also worth knowing how to bleed air other than the classic ones. In the case of a ladder radiator, we must: first close the thermostat, open the air vent and watch the water flow out. Only when it starts flowing evenly can we close the valve.
On the other hand in cast iron models, it is necessary to loosen the screw connections at the radiator valve. However, if the radiator does not have a manual air vent, we must use a thin wire or a needle to press the automatic air vent mushroom.
