a Power flush and what are the benefits?
A powerflush is a cleansing process which aims to remove deposits
of sludge, rust and any other debris from your central heating
system. These contaminants, if left, can seriously affect the
efficiency of a heating system and in severe cases a powerflush
is the only option available.
you might need a powerflush
There are a number of signs to look for before deciding to go
ahead with the powerflush process. These include cold areas on
radiators, excessive noise from the boiler or the heating system
pump, discoloured water when you bleed the radiators and the
slow warming of the heating system. You might also notice the
tap water getting cloudy, especially if there is a build up of
limescale as well.
It is also recommended that the powerflush process is carried
out if you intend to connect a new boiler replacement to an old
heating system. This is because most new boilers are condensing
boilers and any contaminants already present in the heating system
can quickly damage the internal pipe work of the new boiler.
The overall aim of a powerflush is to restore the full circulation
of water around the central heating system, however, it can also
eliminate noise from the boiler and the pump as well. This means
that the entire system has to be flushed in order to get the
A heating engineer will connect a powerful high flow/low pressure
pumping unit to the central heating system - either to the circulation
pump in regular boiler systems or the pump head in combination
boilers - and with the help of high strength cleansing chemicals
will flush out anything in the system.
