Radiators can fail to give optimal functionality from time to time, and in many case, the solution lies in bleeding the radiators. This gives the system that necessary boost and enhances its efficiency. Those with radiators installed in their homes are advised to bleed them on a regular basis. The process of bleeding a radiator may sound complicated to a first time user. However, this is a simple process that only required a key and a suitable container or rag. It also does call for care and attentiveness when being handled.


The holistic function of any radiator is to provide heat. If that heat is not circulating properly in the radiator it means that it has trapped air, which is blocking the circulation. You can tell if that is the case with your home radiator by feel the heat at the top and the bottom of the radiator. You will note that the top is cold while the bottom section is warm. In some radiators the effective are quite apparent with the entire system failing to heat up.


This calls for bleeding, and before you begin working on your home radiator to bring it to its prime functionality, you need to ensure that the system is not running. You can also opt to give it some time to cool a bit, depending on the heat in the radiator.


Most radiators will have a section on the top edges where the bleeding takes place. At times, people will buy a radiator and fail to note whether it has a key to the bleeding valve or not. You can as well go and buy the key or improve using a screwdriver. Of note however, is that you will not turn the valve and completely open it. Bleeding only requires a slight opening of the valve, and the trapped air will escape through the valve. Usually turning the key half way counterclockwise is enough for the radiator to bleed.


It is important to bear in mind that heat in a radiator is trapped; hence, there is compressed pressure and hot air and water in the radiators. Therefore, when bleeding it, you will note a hissing sound that will be as a result of the air escaping through the open valve. You will also not some water dripping from the valve and this is where the container or rag comes in, to ensure that the water does not find its way to the floor. When hissing subsides and only water is coming out, you can then close the valve and then turn on the radiator.
