How To Bleed a Radiator?

If your heating system is not doing its job, chances are, it contains air bubbles.

To bleed a radiator, you will have to release basically pockets of air trapped in the central heating system that keeps it from functioning properly.

The only way of getting the heating of the system back to optimum levels is by letting out air that has become trapped inside. This process is known as “bleeding” and it can either be done by yourself. Otherwise please call a professional to get rid of the cold spots and improve the efficiency of your radiator. Since bleeding radiators is relatively easy, let’s take a look of how you can accomplish this by the DIY method.

Step One:

First, you will have to turn on the heating system so that all of the radiators that have been installed in your home are on.

Step Two:

You will have to wait a while to make sure that all of the radiators in your home are fully heated before moving on to the next step. In order to force out the trapped air in the heating system you will have to build up pressure inside the radiators.

Step Three:

Once the radiators have been heated properly, check each of them individually to make sure all of the parts of each radiator is warm. Since the radiators are going to be hot, it is advised to be careful while inspecting so you don’t burn your hands. If you find that there are cool spots particularly towards the top portion of the radiator, it could be trapped air which you will need to bleed out of the radiator. Once you have found all the cool spots in the radiators, it’s time to move to the next step.

Step Four:

Now it is time to bleed the radiators. Switching off the heating system will allow you to handle the radiators without getting burnt. You will require a radiator key you can purchase it at any hardware store, or a flat blade screwdriver. You will find a valve at the top end of the radiator. Attach the radiator key to the square bit that is in the center of place the screwdriver into the groove. Be careful to hold the radiator key or the screwdriver with a cloth, and have another cloth ready to catch the leaking water. Then slowly turn anti-clock wise. If the air is escaping you will hear a heating sound. Once there is no more gas left inside the radiator, liquid will begin to pour out. Therefore you will need to close the valve as quickly as you can. You should be careful here too. Since the liquid is likely to escape like a jet instead of a slight dribble.

Step Five:

Once you have bled the radiator it’s time to find out if it worked. Take a look at the boiler gauge. If you find that the pressure is low you will have to top up. Please top up with the filling loop which is in place at the top of the boiler. Now, run another hot test to check if your efforts were successful.
