The first step to effectively bleeding your radiator is proper preparation. Let’s gather the necessary tools: a special vent wrench (available at a DIY store for about PLN 5) or a flat screwdriver, a water bowl and an absorbent cloth that will protect the floor against any possible leaks. To ensure that the entire process runs smoothly, make sure that the radiator is cold – it is best to bleed it before the heating season starts or after turning off the heating. Let’s identify the air vent, which is usually located at the top of the radiator, on the opposite side of the control valve.
Before we start the actual bleeding, let’s set the thermostatic valve to maximum value. This procedure ensures free flow of water in the installation and prevents additional problems during operation. Using a bleeder wrench or a screwdriver, gently unscrew the bleeder, keeping a bowl under it in case water leaks out. In the first phase, you will hear a characteristic hissing sound, which means that the air is starting to leave the radiator. Let’s wait patiently until the hissing stops and a steady stream of water starts flowing from the vent. This is a key moment that proves… complete removal of air from the radiator.

Once the water flow has stabilized, tighten the vent thoroughly, taking care to ensure that do not damage the thread – Unnecessary voltage may lead to leaks. Next, let’s check that the air vent is working properly and that there are no leaks. Let’s return the thermostatic valve to its original setting and then repeat these steps for each radiator in the house that requires bleeding.
This is crucial when bleeding radiators being careful and preciseto avoid problems that could affect the operation of the heating system. If we notice that the water flows out under too much pressure, is dirty or contains impurities, it may be a signal of more serious problems in the heating system – in such a case, it is worth considering consulting a specialist. Malfunctioning installations may result from buildup in the pipes or incorrect pressure in the system.

Another important aspect is appropriateness sequence of bleeding radiatorsespecially in multi-story buildings. It is best to start this process with radiators located on the lowest floors and then gradually move on to devices located above. This strategy allows for more effective removal of air that naturally moves towards the top of the installation. Remember to carry out each bleeding step with patience and precision, especially if we are dealing with more complicated systems, such as old cast iron radiators.
Once you’ve finished bleeding, it’s crucial checking the pressure in the heating systemthis applies in particular to installations using an individual boiler. The pressure drop after bleeding is a natural phenomenon, so it may be necessary to top up the water in the installation to the recommended level. Incorrect pressure leads to uneven heating of radiators or disruptions in the operation of the entire system. Regular inspection and maintenance of your heating system, including annual bleeding, are key activities that ensure long-term efficiency and minimize the risk of costly repairs.
