Power Flushing

.
Over time, sludge and dirt can build up in your central heating system reducing circulating efficiency and causing a degradation in performance.Cold spots on your radiator could be an indication that your central heating system needs a clean.
.

How It Works A Power Flush works by connecting a powerful cleaning unit and magnet filter to your central heating system in such a way that water flows from the radiators to the magnet filter to collect iron oxide sludge.A phosphoric acid based rust removal chemical is added to the system and the boiler is switched on. Radiator surface temperatures are then measured using infrared thermometers to detect cold/rust spots.

By concentrating flow through individual radiators and vibrating the radiators with a special device, rust particles are dislodged and pass through the pipework to the magnet filter where they are trapped and prevented from re-entering the heating system.Once the rust has been collected, all radiators, heating coils and pipe work are power flushed with clean water until water samples tested using special electronic meters show clean and neutral readings.

.
After this stage a small amount of neutraliser is added to ensure there is no residual phospohoric acid in the system, then a rust inhibitor is added.Finally the power flush system is removed, the heating turned on and all radiators balanced to optimise system efficiency.
