Product information

Fernox Central Heating Protector F1 500ml an inhibitor which prevents corrosion and limescale formation in central heating systems. This high-performance product offers superior protection by uniquely combining three inhibitors of organic particles, which bind to the metal within the heating system to protect from debris alongside anodic inhibitors which react with the system’s metal surface to create a protective layer, and cathodic inhibitors that combine with hard water salts to form an insoluble layer. Fernox Protector F1 also includes enhanced a pH buffering to ensure the system water pH level does not drop below 6.5 or above 8.5 – the optimum pH range for preventing corrosion and limescale build-up. In line with BS 7593:2019 regulations and best practice, and for long-term protection of the system, concentration levels should be maintained and checked annually as part of the boiler or system service. Protector F1 is compatible with all other Fernox products and is suitable for use with all materials and metals used in central heating systems, including aluminium.
