In order for the radiators to function properly, it is necessary to ventilate them regularly. Fortunately, we can handle this task even without professional help. How to vent the radiator?
An unvented radiator is quite problematic and we can lose a lot of heat because of it. All cast iron and aluminum radiators must be vented. In this way, we can save a lot on heating bills. How to bleed the radiator? It’s not that complicated at all.
How do you know if the radiator needs to be bled?
Radiators that have not been vented for a long time often make characteristic sounds. You can hear the water humming and bubbling in them. This is a clear signal that the water level in the system needs to be maintained by venting the radiator.
If the radiator heats up unevenly, you need to vent it. When you notice that only the lower part of the radiator heats up, it means that there is a lack of water in it. The recipe for this problem is to vent the heating system.
Bleeding the radiator. How do you do it?
Bleed the radiators regularly as this helps a lot. A clogged radiator cannot work properly and cannot provide us with enough heat. This can be reflected in higher bills during the heating season. In some situations, such a radiator may stop heating completely. You don’t need professional help to vent the radiators – we can do it ourselves.
Cast iron and aluminum radiators can be vented without major problems. The procedure is quite similar in both cases. In order for everything to go smoothly, we will need a wrench or screwdriver, a cloth and a large bowl.
We start by setting the temperature to 0 or turning off the supply valve. The radiator must be cold. Then we unscrew the screws using a key. We do it very slowly and carefully. When we hear a hissing sound, it means we have done our job well. Water should start to leak out. We wait until the flow stabilizes. At first, the water will flow erratically, but when the flow stabilizes, the radiator no longer contains air. We can turn it on and use it as usual.
It is worth remembering that air in the radiators is a completely normal phenomenon – it does not indicate any malfunction of our radiator.
