A system heating power flush is the use of specialist equipment and chemicals to clean a heating system of sludge and debris which can cause blockages in pipework, cold spots on the radiators or damage to the boiler.
Power flushing can be beneficial in increasing the life of the heating system including the radiators, pump and the boiler. also increasing the efficiency of the heating by removing debris in the radiators making them more efficient and saving gas and money. A power flush can also be used to help with flow problems where there may be a blockage or partial blockage in the pipework stopping one or more radiators from getting hot or causing them to heat up slowly, the high flow pump used pushes water around the system at high velocity to move the debris and help solve circulations and flow issues.
Having a power flush before a new boiler is installed can be very important when it comes to the warranty that comes with a new boiler especially when it is a combination boiler (Combi) boiler that is to be installed. It is important that the system is power flushed because the water ways inside a combi boiler are smaller than a conventional or system boiler, this means that it can become block easier than other types of boiler. These blockages can cause the boiler manufacturer to invalidate the boilers warranty.
