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, in conjunction with SYSTEM PRE-CLEAN, is also 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.
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.
I liked how clearly Andy explained what he was going to do. He was very thorough and I was very pleased with the boiler service. Andy looked very smart and came across in a professional manner. I will definitely be using him again and would be happy to recommend him to anyone I know. Thanks very much. P.S. Liked the shiny shoes!Miss Bishop (Bath)
