Corrosion within central heating systems has been a problem for the end user and heating engineers and plumbers for years.

Although most system components are designed with a life expectancy of 15-20 years, the build up of magnetite sludge and subsequent corrosion can often shorten this and lead to lower heat transfer and poor system performance. This dense corrosive, black sediment can clog pumps, reduce water flow and lead to cold spots in individual radiators with advanced states of corrosion indicated by black water being drawn from a radiator drain valve or air bleed.

Power flushing is the generic term for cleaning a central heating system of this damaging sludge with the aid of chemicals and a powerful self-contained flush-ing unit that combines a flow-reversing valve to ensure a high degree of system cleanliness.

Cost guide goes here, underpinned by potential savings and lower carbon emissions

• Extended boiler life
• Lower carbon emissions
• Save £'s on boiler repair/replacement
• Higher fuel efficiency
• Hotter radiators & quicker warm up
• Quieter boiler
