Fernox Cleaner F3 is a universal, pH-neutral central heating system cleaner designed to remove sludge, limescale and other debris from domestic heating systems.
It is suitable for both new and existing central heating systems and can be used as part of a system clean or prior to installing a new boiler. F3 is non-foaming and compatible with all common heating system materials, including aluminium.
One 500ml bottle treats up to 130 litres of system water, equivalent to approximately 16 radiators or 250m² of underfloor heating.
Fernox Leak Sealer F4 is an internal leak sealer designed for use in central heating systems to seal small, inaccessible leaks and weeps that can cause pressure loss and boiler breakdowns.
Once added to the heating system, F4 circulates through the system and seeks out areas where oxygen is entering through microscopic leaks. It then forms a polymer seal around the affected area, helping to stop the leak without the need to drain down the entire system.
Fernox F4 is effective within 1 to 24 hours and is designed to remain permanently in the system. It is compatible with all common heating system metals and materials, including aluminium, and is formulated not to cause blockages or restrictions in vulnerable components such as pumps, air vents and heat exchangers.
One 500ml bottle treats up to 130 litres of system water, equivalent to up to 16 radiators or 250m² of underfloor heating.
Fernox Protector F1 500ml is a high-performance central heating inhibitor designed to provide long-term protection against corrosion and limescale formation in domestic heating systems.
It combines multiple corrosion and scale inhibitors to protect the metals within the heating system and help prevent the formation of damaging sludge and deposits. Enhanced pH buffering helps maintain system water between pH 6.5 and 8.5, the optimum range for protecting mixed-metal heating systems.
One 500ml bottle treats a heating system of up to 130 litres, 16 radiators or 250m² of underfloor heating. Protector F1 is suitable for all types of boilers, radiators and pipework systems and is compatible with commonly used heating system materials, including aluminium.
For best results, contaminated systems should be cleaned and flushed before adding Protector F1. Fernox recommends checking inhibitor concentration annually as part of routine boiler or heating system servicing.

The BiWorld Smart Mag Compact Filter Chemical Pack is a complete solution for protecting your central heating system from sludge, scale and corrosion. The filter uses powerful magnets to trap ferrous debris, such as magnetite, which can cause blockages and reduce the efficiency of your system. The chemical pack contains two products: B3 Cleanser, which removes existing sludge and scale, and B1 Protector, which prevents further build-up.
The filter is easy to install and maintain. It can be fitted on either the flow or return pipework and has a built-in isolation valve for easy servicing. The chemical pack is also easy to use, simply add the required amount to your system and circulate for the recommended time period.
The Wyndam Branded Build Cert Calmag Chemical Inhibitor (1L) WYN-BC-1000 is a premium solution designed to protect your heating system from scale and corrosion. Formulated to meet BuildCert standards, it ensures optimal performance and longevity of your boiler and radiators. Easy to use and highly effective, this inhibitor is a must-have for maintaining efficient heating systems.
Fernox Biocide F7 200ml is a high-performance biocide designed to prevent bacterial contamination and fungal growth in underfloor heating, low-temperature heating and chilled systems.
It also helps clean and prevent the recurrence of microbiological fouling, including jelly-like deposits caused by fungal growth in feed and expansion cisterns. Biocide F7 starts working within 24 hours and provides both short-term disinfectant action and longer-term preservation.
One 200ml bottle treats up to 150 litres of system volume or up to 280m² of underfloor heating. Fernox recommends using Biocide F7 alongside a Fernox Protector, such as Protector F1, to provide protection against corrosion and scale.
The Wyndam Branded 22mm Electrolytic Water Conditioner is designed to reduce limescale build-up in domestic water systems, protecting plumbing and appliances. Ideal for 22mm pipework, it prevents scale formation by altering the properties of hard water minerals, ensuring longer-lasting efficiency for your water system.
Fernox Antifreeze Protector Alphi-11 is a combined antifreeze and corrosion inhibitor designed to protect domestic central heating systems against freezing, internal corrosion and limescale formation.
Alphi-11 contains mono-propylene glycol and provides frost protection while helping to maintain the long-term efficiency and lifespan of the heating system. It is suitable for use with all common heating system metals and materials, including aluminium.
A minimum in-use concentration of 25% is recommended to provide adequate corrosion protection. At this concentration, Alphi-11 provides frost protection down to -11°C. Increasing the concentration to 40% provides protection down to -22°C.
Alphi-11 is suitable for heating and chilled-water systems and is compatible with other Fernox products. For new or untreated systems, Fernox recommends thoroughly cleaning and flushing the system with Fernox Cleaner F3 before adding Alphi-11.
Fernox Protector F1 265ml is a high-performance central heating inhibitor designed to provide long-term protection against internal corrosion and limescale formation in domestic heating systems.
