Power Flushing
Central Heating System
Power Flushing
The core component of a heating system is the boiler. When a boiler is renewed,
the boiler manufacturers' Benchmark scheme requires that the system be
thoroughly cleansed to British Standard BS7593, and as from 2005, with reference
to the interim DWTA industry Standard. Currently, best factory practice is
considered to be to power flush the system.
Power flushing is the fastest and most effective way to flush heating systems,
and involves minimal disruption and dismantling.
We use purpose built power flushing pumps, designed to cure the circulation and
boiler noise problems caused by accumulations of sludge corrosion deposits and
scale which are found in most ageing central heating systems.
The power flushing pump is temporarily connected into a heating system during
the flushing process. The high water velocity, combined with instantaneous flow
reversal, dislodges and mobilizes sludge and corrosion deposits.
Having loosened the debris, the pump expels it from the system to waste, using a
high velocity flow of fresh water.
Radiators are individually flushed without removal or disconnection from the
system. After the power flush, the systems is full of clean water, and
instatement to normal operation takes only a few minutes.
A power flush can be extremely effective in cleaning systems that have corrosion
problems as a result of a design fault, but we strongly recommend that such
design faults be rectified before power flushing commences.
The success of a power flush will depend on the level of heating system
corrosion which has occurred beforehand. The process will cure most circulation
problems, but cannot undo the corrosion and gradual decay that has led to the
need to power flush the system.
Whilst it is rare for a heating system to experience leaks after the power
flushing process, it is not possible to inspect a system internally beforehand,
and the need to use a flushing and dispersing chemical for effective cleansing
means that occasionally we may find a leak.
The advanced stage of corrosion required for such a situation means that the
leak would occur imminently even without a power flush. We believe that it is
better that it occurs whilst we are present to remedy the problem, rather than
for it to arise over a weekend or whilst the house is unoccupied.
Systems which have been neglected over a period of time, or have not been
treated with an effective corrosion inhibitor, may have severely compacted
corrosion debris, in the pope work, radiators, or boiler, and it is possible
that even after the power flush, some radiators may still not be fully
effective, or boilers on the margin of failure may cease working due to sludge
and debris later breaking loose and collecting in the heat exchanger.
The price that we have stated allows for a standard power flush only and if and
of the above or similar problems arise during or after the power flush well not
hold ourselves responsible in any way, and any further work required would be
carried out at an additional cost.
