Flushing radiators can certainly help improve their efficiency of performance, however it is quite an involved job and not really a ‘quick fix’.
You can check for cold spots at the foot of your designer radiators to see if they need flushing – if they are hot at the top and cold at the bottom, it probably indicates a conglomeration of debris and sludge within the radiator.
To flush the system, you can remove the radiator from the wall and flush it out using a pressure washer or hosepipe, ridding it from any unwanted debris that could be causing a blockage and preventing the rad from running efficiently.
