Reasons for power flushing
We are experts in Power Flushing old systems. All systems need power-flushing before a new boiler is fitted, and need power-flushing to maintain the good regulation of the system. Power-flushing will soon be a regulation to be followed for all official installers.
This is 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 is made even more effective with the addition of powerful cleansing and mobilising agents.
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.

Boiler Manufactures will not guarantee your new boiler installation if the system is not chemically cleaned. The British Standards and the Benchmark demand that the system should be thoroughly cleaned. 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.
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.

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.
