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. 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
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.
Existing 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.
The power flushing process is a versatile, easy to use
and highly effective method of flushing heating systems. 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.
Once 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
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!
Power 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!
