Bleeding a radiator is a process which allows you to safely remove air that is trapped inside. When gas or air is trapped inside it prevents your device heating properly. By bleeding the radiator you will be able to make a huge difference in how your heater functions and also save energy. It is a very simple process that can be completed in just four easy steps. However, while this is not a difficult process, you should follow each step carefully so that no damage will occur to your heating system and there will not be any injuries. If you are at all unsure about the process, then call a qualified professional instead.
First of all you'll need to switch your heat system on so that your radiator will become hot. You'll need to ensure that each radiator inside your home is powered on and working properly. This may require you to increase the temperature gauge.
Next, you'll need to figure out which of the radiators located inside of your home need bleeding. Once each one has heated up you should evaluate each heater to make sure that every part is getting warm. Radiators can become very hot so be sure to use caution so that you will not end up burning yourself. If there is a problem, it could end up getting much hotter than normal so be aware of that fact before starting your inspection so that you do not injure yourself.
If there are cool spots located on your radiator that means that it is very likely that gas or air is trapped on the inside and you'll need to bleed the device. It is likely that gas or air will become trapped on the highest level that is located inside of your home. This is because on many occasions air will become trapped inside of a coil that is located inside of a cylinder used to transport hot water which is often located in the highest part of the entire system.
Next you'll need to bleed the radiators, before you do this you'll need to ensure that the central heating system has been turned off. In order to bleed the heater properly you'll need to have the correct key for older models. Most new models will allow you to do so by using a flat screwdriver. You will want to hold onto the key or if you are using a screwdriver then you must hold that with a towel and have another towel on hand in order to absorb any dripping that may occur. Turn the key slowly counter clockwise. If any gas happens to escape you will hear a sound similar to hissing while you are turning the key. When no gas is present inside liquid will start to come out of the valve and you'll need to close the valve immediately.
Afterwards, you'll need to do a pressure check by looking at your gauge which is located on the radiator. If you have low pressure then you'll have to go through a process that is known as topping up by the use of the lever that is on your radiator, often referred to as the loop. It is wise to conduct an additional heat test to make sure that you did the job correctly.
