Posted on October 9, 2012 · Posted in Power Flushing

Does your radiator have cold spots? If so you may need to bleed your radiators to release the trapped air. This article shall explain how to bleed radiators. You can install automatic radiators bleeders; however, the process is quite straightforward and possible to complete yourself.

Before bleeding radiators we suggest covering the carpet or floorboards under the radiator with a towel or kitchen paper. This shall ensure that any water that escapes will not mark your floor. Next, turn off your central heating system for safety reasons. Then, use a screwdriver with a flat blade or a radiator key (available to buy from any DIY store) to open the radiator valve counterclockwise until the trapped air and water escapes. The valve can usually be found on the side of your radiator and often is easily identified by its bright red handle. Once all of the water has finished trickling out you should retighten the valve. It may be necessary to top up your boiler after bleeding your radiators. Finally, turn your heating system back on and check to see whether the problem has been rectified.

If bleeding your radiators does not solve your heating problem you may wish to consider having one of Gas Boilers Servicing qualified engineers give your system a power flush. A power flush can help to remove harmful iron oxide (rust), limescale, magnetic particles and debris from your system (usually referred to as ‘sludge’). This sludge can corrode the copper pipes if left to accumulate, which will result in you having to replace your whole system sooner, an expensive inconvenience.
