If you are experiences any of the following symptoms then the chances are your central heating system is in need of a forced cleaning process commonly known as Power Flushing
Heating system slow to warm up
Combination boilers being unable to deliver constant hot water
Unusual system or boiler noises
Repeated pump failure
Radiators need frequent bleeding
Radiator water black with iron oxide sludge
Power flushing is a highly effective cleansing operation which works by pumping water at a much higher velocity than usual through the heating system, to loosen and immobilize harmful corrosion deposits and suspend them in the rapidly moving water. The process is made more effective by specialist cleansing chemicals and an instantaneous flow reversal device which creates turbulence in the radiators to optimize “pick up”. Once loosened, the unwanted debris is purged from the system with clean water. At the end of the flushing process the system contains fresh clean water, and reinstatement of the system to normal operation takes only a few minutes. During the process, radiators are individually flushed without removing or disconnecting them from the system by directing the full output of the pump through each radiator separately. The objective is to restore systems with circulation and boiler noise problems (caused by sludge and corrosion deposits) to optimum operation. Power flushing removes these deposits and the problems that they cause.
Clean Heat UK uses the latest equipment and chemicals to restore your heating system. We constantly analyze the system before, during and after the cleaning ensuring the process was successful
Under part L of the Building Regulations Power Flushing should also be carried out to all new systems and before fitting a new boiler, it is important when installing new boilers into old systems that all the sludge is first removed from the system or this could accumulate in the new boiler and lead to premature failure.
