MagnaClean Professional sets an industry standard for plumbing and heating engineers when it comes to protecting and maintaining both new and existing heating systems. In an age of advanced and high efficiency gas and oil boilers there has never been a greater need to safeguard what amounts to one of the most expensive investments in the modern home – the central heating system. Even a small build-up of iron oxide in a standard or modern efficiency boiler results in substantial efficiency loss and fuel wastage. So, not only does the system perform inadequately, it also costs more to run and maintain. MagnaClean Professional is a proven, high efficiency, full-flow magnetic filter designed to tackle all central heating systems removing virtually 100% of the suspended black iron oxide.
