The MagnaClean filter is a high efficiency magnetic filter which removes virtually 100% of circulating sludge. This comes from iron oxide deposits in your central heating system and removing these can help keep your system operating at its best. Even a small amount of sludge in the system can dramatically decrease its efficiency, causing cold spots in your radiators and reduce the lifespan of your boiler. Using MagnaClean could help you consume less energy, whilst keeping your home warm, and lead to lower heating bills.
Our Gas Safe registered engineers can fit a MagnaClean filter on your system.
