Power Flushing of your Central Heating System
Power flushing 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 can be made even more effective with the addition of powerful cleansing agents. The objective is to restore you central heating system with circulation and reduce boiler noise problems so that it works at optimum operation. Power flushing your central heating removes deposits and the problems that they cause.It is prudent to power flush a central 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.J Thirkell Heating recommend you power flush your central heating system every 5 years in order to maintain the efficiency of your system.
HOW DOES IT WORK?
The power flushing pump is connected into the heating system, either across standard circulator pump couplings, across the tails of one radiator/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 powerflush process, radiators are individually flushed.At the end of the flushing process we finally add an “inhibitor”. This protects your central heating system from further deterioration caused by sludge and scale.
