Abbey Boilers heating engineers are fully experienced and qualified cleaning out your heating systems. We operate in HorshamWest Sussex,  Surrey and South West London.

POWER FLUSHING  &  SYSTEM CLEANING are commonly known  terms 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 Kameo.

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 is 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.

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.

How does it work?

The 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 cleaning  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.
