Bleeding A Radiator

Clearing the valve in the radiator and getting rid of trapped air is the best way to get the hot water radiator functioning properly. If you experience any problems with the heating process, you should try to bleed it out as this will help in improving the performance of the radiators. Continue reading to learn just how to bleed the radiator:

Turn On the Radiator to Heat it Up

It is important to heat the radiator before the bleeding process starts. Increase the temperature on the thermostat and try to get the radiator as hot as possible. Before you move further, you should make sure that the radiators have been fully heated so the liquid is free flowing.

Inspect the Radiator

Before you move further, you should use caution and remember that the radiator and its components are hot. Check every area of the radiator individually. This will help you in understanding which part is not heating and which area is functioning properly. The areas that have cool spots mean that there is gas or air trapped in that area. Most of the time, the top part of the radiator tends to be cool as air usually gets trapped here.

Use the Radiator Key or a Screwdriver  

During this process, you should first make sure that central heating system of the radiator is switched off. To bleed the radiator you need a radiator key, or a flat-blade screwdriver. Older radiators may require using the key. You need to move the valve counterclockwise and make sure that the water starts dripping out of the radiator. This process helps in getting rid of air and lets the hot water move into the cold areas.

Keeping a Check on the Pressure

Keeping a check on the pressure is important to do while you are bleeding the radiator. Since the pressure tends to decrease during the process, you should try to use the tap or the lever in your radiator to keep the pressure steady in the boiler.

Once you have completed the process and the radiator is cold again, turn it on to see if it's heating properly. If you were successful, the radiator should heat up and you shouldn't feel any cool spots. If bleeding the radiator didn't work, you should call a professional to inspect and troubleshoot your radiator so you are able to keep your home warm all winter long.
