Restore your system to new
‘POWER FLUSHING’, ‘JET FLUSHING’ & ‘HARD FLUSHING’…
…are all expressions used (in the heating trade over many years) to denote 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.
The process can be made even more effective with the addition of powerful cleansing and mobilising agents.
Symptoms diagramThe objective is to restore systems with circulation 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, in conjunction with a SYSTEM PRE-CLEAN, 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 before use.
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.
It is always a good idea to power flush your system before fitting a new boiler.
REDUCED NOISE & INCREASED EFFICIENCY
New boilers are highly efficient which means that they are more susceptible to problems caused by debris in the system water
Removing dirt and junk from your radiators makes them much more efficient and of course, warmer.
How does it work?
The CLEARFLOW 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 CLEARFLOW process, radiators are individually flushed, without removing or disconnecting them from the system, by directing the full output of the pump through each radiator separately.
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.
