Power Flushing
Power Flushing in Kingston & SW London
Clears the sludge that's costing you heat and money.
About this service
Power Flushing in South West London, done properly the first time
Cold radiators at the bottom, a kettling boiler, or repeated pump failures usually mean magnetite sludge built up in the system. We connect a high-flow pumping unit, reverse the flow through each radiator to lift the debris, then dose the system with corrosion inhibitor and recommend fitting a magnetic filter so it doesn't build up again.
