What is it? Why do I need it?
System alterations and the increased efficiency of a new boiler can dislodge accumulated debris which may then gather in the boiler heat exchanger resulting in system noise, reduced efficiency and, in severe cases, boiler failure.
An increasing number of systems are found to contain corrosion and sludge, even if no flow problems are currently apparent.
Modern high efficiency, compact boilers, are more susceptible to circulation problems caused by corrosion and debris in the system water.
Parry and Tweed highly recommends that older heating systems are power flushed immediately before renewing a boiler or replacing thermostatic valves to prevent possible future problems.
Power flushing is a process by which water, at high velocity but low pressure, is forced through a central heating system. The effectiveness of the process is increased by adding chemical cleansing and mobilising agents.
The power flushing equipment is connected to the system across the flow and return pipe work. The high speed flow generated by the equipment, together with its quick reverse capability, will dislodge and flush deposits and corrosion through the machines full-flow drain whilst, at the same time, filling the system with fresh water from a hard connection via your water main. Power flushing is much more effective than traditional methods.
Boiler manufacturers are increasingly reluctant to carry our warranty repairs where it is suspected that the fault has been caused or exaggerated by debris/sludge in the system.
