Fernox Cleaner F3 265ml is a universal, fast-acting, pH-neutral cleaner designed to remove sludge, limescale and installation debris from central heating systems.
Suitable for both new and existing heating systems, Cleaner F3 helps remove contaminants that can affect heating efficiency and contribute to boiler noise. It can also be used when pre-commissioning new systems to remove flux residues and other installation debris in accordance with BS 7593:2019.
Compatible with all metals and materials commonly used in heating systems, including aluminium, Fernox Cleaner F3 can be used with manual or magnetic flushing methods and with powerflushing equipment where systems are heavily contaminated.
One 265ml bottle treats an average domestic heating system of up to 100 litres, up to 12 radiators or 190m² of underfloor heating. It can also be dosed through a Fernox TF1 filter.
Fernox Cleaner F3 500ml is a universal, pH-neutral, non-foaming central heating system cleaner designed to remove sludge, limescale and other debris from existing heating systems.
Cleaner F3 can help restore heating efficiency and reduce boiler noise caused by system contamination. It can also be used when commissioning new heating systems to remove flux residues and installation debris before the system is protected with a central heating inhibitor.
Suitable for all metals and materials commonly used in heating systems, including aluminium, Fernox Cleaner F3 can also be used with powerflushing equipment to accelerate the cleaning process in existing and contaminated systems.
One 500ml bottle treats up to 130 litres of system water, up to 16 radiators or up to 250m² of underfloor heating.
