There are thousands of ageing central heating systems with circulation and boiler noise problems caused by the accumulation of sludge, corrosion deposits and scale, but traditional methods of flushing just don't get rid of all the debris, and problems often quickly return.
  Power Flushing is an expression used to denote the process by which heating systems are forcibly cleansed using water at high velocity, but low pressure, so no physical damage is caused to the system. The process can be made even more effective with the addition of powerful cleansing and mobilising agents. View diagram showing system requiring a power flush.Power flushing is also an excellent way to pre-commission clean new heating systems, to remove excess flux, swarf and other debris and the grease and oil used to prevent rusting of components before use.

When To Carry Out a Power Flush
It is prudent to power flush a heating system immediately before fitting a new boiler to an existing system to prevent possible future problems. Many systems are found to contain corrosion and sludge, even if no flow problems have yet shown themselves.

scaled pipeExisting debris is often mobilised by alterations to the system/piping and the increased efficiency of the new boiler, and may then accumulate in the boiler heat exchanger, causing noisy operation, reduced efficiency and, in extreme circumstances, failure of the boiler. The high efficiency and compactness of modern boilers, developed to minimise fuel costs and pollution, means that they are more susceptible to problems caused by debris in the system water.

Power Flushing

By utilising the flushing pump, it enables heating systems to be purged of sludge, scale and corrosion deposits with minimal dismantling and disruption.

How does it work?
The power flushing pump is simply connected into the heating system, either across standard circulator pump couplings, across the tails of one radiator, or wherever most practicable. The powerful flow, combined with instantaneous flow reverser device, will dislodge and mobilise deposits and corrosion which resist traditional system cleaning methods.

Power Flush FX2:  dissolves iron oxides, sludge and limescaleOnce the corrosion and sludge deposits have been loosened and mobilised, fresh clean water is forced through the heating system, pushing the contaminated water out through a full bore dump valve to waste. 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.

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.

System flushing will not remedy design or mechanical faults, which should be rectified, but in many cases it will cure the problems caused by these.  Power flushing prices start from £375.00.

Employ a Trained Engineer to Perform Your Power Flush
It is advisable to employ a trained engineer to carry out your power flush because an untrained person can easily ruin your central heating system by, for instance, using an incorrect solution to clean a boiler containing an alumnium heat exchanger. Click here to see if your boiler has an aluminium heat exchanger.  If it has, make sure FX2 isn't used to clean the system!

tds meterPower Flush Training
Fox & Co tradesmen have attended the Kamco training courses in power flushing and use only the latest, most up to date Kamco equipment when performing a power flush. We also analyse the water on completion using a TDS meter to compare the contents of your system with the water from your kitchen tap!
