LavaTap - Fernox Power Cleaner F8 - a professional-grade cleaning solution designed for dirty, heavily contaminated central heating systems. Its fast-acting, super strength formula removes sludge, rust, and scale that restrict water flow and reduce system efficiency. This pH neutral, non-acidic. central heating cleaner is safe to use with all metals and materials found in heating systems, including aluminium and rubber seals. Fernox F8 is compatible with manual flushing, power flushing units, and magnetic filters. One 500 ml bottle treats up to 130 litres (up to 16 radiators) or 250 m2 of underfloor heating -covering the vast majority of UK homes. Application is simple: dose via a radiator, towel rail, filling loop, or Fernox TF1 filter. Once circulated for up to 1 week, Fernox F8 quickly breaks down deposits without requiring neutralisation. Then drain and refill the system ensuring to add central heating inhibitor to ensure ongoing protection. For full BS 7593:2019 compliance and long-term protection, follow up with Fernox F1 Protector or equivalent central heating inhibitor. Whether you're a heating engineer or DIY user, Fernox F8 is the ideal radiator flush for restoring efficiency and extending system life.
