The need for power flushing comes from a build-up of oxide sludge and calcium in the central heating system. Sludge or calcium build up in a heating system means there could be an underlying problem that is allowing air to get into the central heating system, causing radiators and heat exchangers to corrode. This leaves rust and debris in the bottom of radiators which corrodes down into oxide sludge. This then leads to blocked waterways in radiators, pipe work and heat exchangers. Blockages slow down the transfer of heat which causes pipe, valve and heating control server damage. It will, in some cases, lead to boiler replacement.
A power flush is designed to remove this sludge build up which should improve the efficiency and lifespan of your central heating system, and will mean less breakdowns. A power flush should be carried out by a qualified central heating engineer - it is dangerous to try and attempt it yourself. We would recommend getting a power flush when you notice the following symptoms in your boiler.
