CHEMICAL FLUSHING PROCEDURE – WHICH CHEMICAL TO USE
Which chemical to use? POWERFLUSH FX2, or HYPER-FLUSH.
Both of these chemicals will remove sludge and scale from a central heating system.
POWERFLUSH FX2
Use Powerflush FX2 when:
~ You consider the system to be heavily sludged,
although basically sound and in reasonable
condition.
~ There are no aluminium heat exchangers or
radiators present in the system.
~ The system does not have elderly galvanised steel
or stainless steel pipework installed during the 1960s
copper shortage crisis.
~ You consider that there may be limescale deposits
present in the boiler or system.
How much to use?
2.1/2 litres per ten radiators (or a little more if you
consider the system to be heavily sludged).
Where and when to add FX2?
Into the tank of the Quantum whilst powerflushing,
but not beforehand.
Temperature required?
FX2 may be used cold (necessary when changing a
boiler), but works faster with a higher temperature.
The very high flow rate of the Quantum means that
during power flushing it is not necessary to work at
temperatures above 50°C.
NEVER LEAVE FX2 IN A SYSTEM
HYPER-FLUSH
Use Hyper-Flush when:
~ The system contains aluminium radiators or heat
exchangers.
~ You consider the system to have suffered severe
internal corrosion and metal wastage.
~ The system has elderly galvanised steel or
stainless steel pipework installed during the 1960s
copper shortage crisis.
How much to use?
1 litre per ten radiators (or two litres if you consider
the system to be heavily sludged).
Where and when to add HYPER-FLUSH?
Into the system 3-14 days prior to power flushing (via
the F&E tank, or a SYSTEMSURE injector unit),
Directly into the Quantum tank whilst power flushing.
Temperature required?
HYPER-FLUSH works best at higher temperatures,
and when used to pre-treat a system, it should be
operated as hot as possible.
However, the very high flow rate of the Quantum
means that during power flushing it is not necessary
to work at temperatures above 50°C.
Use both HYPER-FLUSH and FX2 if you consider the system to be VERY HEAVILY SLUDGED.
Add HYPER-FLUSH on a prior visit up to 14 days before the power flush, and ask the householder to leave
the system running as hot as possible.
Use FX2 as usual on the day of the power flush, adding directly into the Quantum tank.
