The most common causes of problems associated with central heating systems are those resulting from corrosion, scale and microbiological contamination.

Whilst there are products designed to resolve these problems the best solution is prevention through the correct flushing and treatment at installation.

The kinds of problems that can be encountered are:

Corrosion affects all water systems with metallic components. The rate of corrosion and possibility of component failure will be determined by materials present, the water quality, system design and operating characteristics.

Failures like pitting which leads to perforation can cause leakage and sludge build-up which can lead to blockages in pipes and radiators, pump and boiler problems and ultimately system failure.

We know that 1.6mm of scale build-up in heating systems will cause a 12% loss in heating efficiency and that 65% of the UK is situated in a hard water area.

Over the years, scale forms around heating coils which means boilers will run longer and hotter, wasting more energy. Scale will reduce the life of hot water cylinders, showers, washing machines, immersion heaters and increase maintenance and repair charges along the way.

Microbiological contamination
Central heating systems can be susceptible to biological fouling by bacteria or mould growths. For example, leathery skins or films caused by fungal growth can be found on the surface of expansion cisterns.

Analysis of the system water will highlight the cause of the problem, and if done early on will identify any risk before significant damage occurs to any component.
