'POWER FLUSHING', 'JET 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 such as FX2 and HYPER-FLUSH, from Kamco.
The 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 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.
CLEARFLOW® POWER FLUSHING
The CLEARFLOW power flushing process is a versatile, easy to use and highly effective method of flushing heating systems. By utilising CLEARFLOW system flushing pumps, heating systems can be purged of sludge, scale and corrosion deposits with minimal dismantling and disruption.
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.
· Extended lifespan of heating system
Firstly, you are increasing the lifespan of your entire central heating system. Sludge can clog your pipes, leading to problems and costly bills for new components or even a new boiler, but after Power Flushing, the lifespan of your system will be extended by up to 10 years.
· Greater efficiency
After Power Flushing, your central heating system will function as well as a new system and will be up to 40% more efficient – no more cold radiators or noisy boilers!
· Cheaper heating bills
As there will no longer be any sludge clogging up your pipes and boiler, the water will circulate much more efficiently, heating the radiators throughout, so you won’t need to turn up your heating so high. This means big savings on your central heating costs – customers commonly save up to 40% on each and every subsequent heating bill after a Power Flush.
· Long-lasting results
If you have your boiler serviced regularly, your central heating system should not need to be Power Flushed again for at least 10 years – that’s 10 years free from patchy radiators, leaking systems and sludge
