Why is system flushing important?
Flushing of a central heating system in accordance with BS 7593 is carried out to remove contaminants such as flux residues, grease, jointing compounds, oxides produced by the corrosion process, bacteria and in hard water areas limescale. If they are not removed, these contaminants form a harmful sludge in the system which reduces the efficiency of the system, causes noise and could potentially reduce the useful life of the appliance.
