What causes sludge in your central heating system? many factors can influence sludge in your heating system, it can be caused by corrosion of your radiators and other parts on your heating system like pumps and motorised valves, the different metals in your system react with each other causing the brown sludge also known as iron oxide, if you bleed your radiators and you see brown sludge then it is more than likely your system requires a power flush.

Having a build up of sludge in your heating system can cause failure to system components like your pump, motorised valves, radiators and your boiler, in worst cases it can cause your boiler to completely shut down due to a complete blockage or with a partial blockage cause your boiler to only run for a short period of time, some components in your boiler are very small and need to pass a certain volume of water through them, when these become blocked or partially blocked the heat from the boiler is not allowed to flow around the system because of this the boiler thinks the boiler is up to temperature and will not produce any more heat until the hot water inside the boiler is cooler in temperature, when your system has a bad build up of sludge it can cause pump failure and many unwanted boiler breakdowns.
