Power Flushing

Power flushing is an excellent way to pre-commission clean new heating systems.
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 mobilized by alterations to the system/piping and the increased efficiency of the new boiler 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 minimize fuel costs and pollution means that they are more susceptible to problems caused by debris in the system water.

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 mobilize deposits and corrosion which resist traditional system cleaning methods.
Once the corrosion and sludge deposits have been loosened and mobilized, 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.

Does My Heating System Need A Power flush?

Little or no hot water coming from taps is due to blocked pipes from build up of 'sludge' and poor functioning heat exchangers.
If black or brown water appears during the bleeding of radiators this means that the central heating system has started to corrode internally.
If the boiler is loud or cuts out it is often A result of accumulated ‘sludge’ or lime Scale in the system. If not rectified it could result in the costly repair or replacement of a boiler.
Black sludge builds up over time at the bottom of radiators due to internal corrosion. A powerflush will remove the sludge and make the central heating system more efficient.
Radiators will be cold at the bottom if the 'sludge' is allowed to build up without powerflushing. The heating system works harder while producing less heat and ends up costing more to run.
Radiators that are cold at the top when the heating is on need ‘bleeding’ due to the build up of hydrogen gases, a by product of rusting.

How Much Will A Powerflush Cost?

An average 3 bed house with seven radiators will cost £300.00. Please add on £30.00 for each extra radiator. This price includes the cost of the chemicals and V.A.T.
