Radiators rust internally producing black iron oxide ‘sludge’. This sludge moves around the heating system blocking pipes, valves and boilers (pumps/heat exchangers/diverter valves).
Power flush equipment, normally set up outside, connects to your central heating and cleans the whole system without having to take off all the radiators.
Powerflush cleaner is added to the system water and starts to loosen the rust. The heating is turned on and radiator surfaces checked for cold spots. By flushing water through individual radiators and vibrating cold spots the sludge is rapidly loosened. The sludge flows from radiators and is collected at our magnet filter.
