POWER FLUSHING
What is power flushing?
New installations
Power flushing is the process by which heating
systems are forcibly cleansed using water at
high velocity, but low pressure, so that no
physical damage is caused to the system.
Our services
The objective is to restore systems with
circulation problems and boiler noise problems
caused by sludge and corrosion deposits to
optimum operation.
Power flushing removes these deposits and
the problems that they cause.
Power flushing, is 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.
Existing installations
It is prudent to power flush a heating system
immediately before fitting a new boiler to an
existing system in order to prevent possible
future problems. Many central heating systems
are found to contain corrosion and sludge, even
if no flow problems have yet shown themselves.
The existing debris is often mobilised by
alterations to the system/piping and by the
increased efficiency of the new boiler. This debris
may then accumulate in the boiler's 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 they
are more susceptible to problems caused by
debris in the system water.
