How to Bleed Radiators

Is your radiator taking a long time to heat up? Or does it feel cold at the top or to the sides? Then perhaps you need to check your radiator’s status. How to bleed radiators is not entirely difficult with the right instruction and can help your heating system if trapped air is the problem.

How to bleed radiators is a simple task, and here’s a very simple guide on how to do it correctly. First of all and most important; turn off your central heating so that it’s safe to bleed the radiator.
Next, find the bleed valve. This is located one side of the radiator and is usually coloured red. Take a cloth and wrap it around the valve to stop water going everywhere when bleeding. Also put a bowl or bucket under the valve and then cover your hands with kitchen gloves or cloth as the water you bleed might be very hot.

Each radiator comes with a bleed key. Take the key and then insert it into the bleed valve. Turn it anti-clockwise so that the air pressure lowers and water begins to escape. Let this run for a few moments then turn the key back clockwise.

If it is still not working and the water inside is dirty, then you may need a central heating flush. This clears all of the debris, dirty and limescale in the heating system, preventing those colder radiators and cold spots on the radiator.

If the water appears dirty, then we at My London Tradesman advise that you seek some immediate services. Your radiator might have a build-up of debris. This is what radiator bleeds are meant to detect.
