Power Flushing


Power Flushing is a very important part of the heating engineers toolkit, restoring efficiency to boilers and radiators, giving customers real savings on energy bills.


The causes of sludge in a heating system are poor design of the system pipework, continual loss of water, whereby the make up tank or filling device is constantly replenishing the water in the heating system or, simply, as in most cases, the age of the heating system. If the problem is due to poor design and continual water replenishment then these faults will have to be addressed before the powerflush is carried out.


If your boiler is noisy or if your radiators are cold at the bottom and hot at the top or you have cold spots on the radiators this usually indicates that there is a build up of sludge at the bottom of the radiators.


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.
