Power flushing  is a highly effective cleansing operation which works by pumping water at a much higher velocity then usual through the heating system, to loosen and mobilise harmful corrosion deposits, and to suspend them in the rapidly moving water. The process is made more effective by specialist cleaning chemicals, an instantaneous flow reversal device which creates turbulence in the radiators to optimise pick up of the debris.

A power flush can restore circulation and efficiency to the heating system by removing these undesirable products. It purges them from the system, and replaces aggressive water with clean water, chemically treated with a corrosion inhibitor to prevent future problems.
