Powerflushing
Why a Powerflush ?
There are thousands of ageing central heating systems with circulation and boiler noise problems caused by the accumulation of sludge, corrosion deposits There are thousands of ageing central heating systems with circulation and scale, but traditional methods of flushing just don't get rid of all the debris, and problems often quickly return. Power Flushing is an expression used to denote the process by which heating systems are forcibly cleansed using water at high velocity, but low pressure, so no physical damage is caused to the system. The process is made even more effective with the addition of powerful cleansing and mobilising agents.
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 it works
Its a 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 process, radiators are individually flushed, without removing or disconnecting them from the system.
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. Prices start from £320 based on an average 2-3 bedroom house.
