Fernox is a leading manufacturer of central heating filters, plumbing consumables, water treatment chemical products and diagnostic testing services.  

The Fernox Protector F1 is the market leading inhibitor and by applying the Fernox F1 Protector to your central heating system you can help to protect it against internal corrosion and limescale build up. This will benefit the life span of the your central heating appliances and can save you a significant amount of money in the future. 

Fernox F1 Inhibitor can be used with all metals commonly found in heating systems and is suitable for all types of boiler, radiators and pipe work systems.

We recommend Protector F1 levels are checked regularly (around once a year). 

Features of Fernox F1

  • Helps to battle corrosion and scale in metal central heating systems
  • Gas savings of up to 15% can be achieved if used in conjunction with Fernox Cleaner F3
  • Carbon footprint certified by the Carbon Trust
  • Reduces the need to vent radiators frequently
  • Reduces sticking pumps and boiler noise
  • Lowers maintenance costs which contributes to a saving on your fuel bills
  • Prevents cold spots in radiators
  • Non-toxic and environmentally friendly

Application and Dosage

The recommended ‘in use’ concentration of Fernox F1 is 0.5%. One 500ml bottle of Fernox F1 can treat an average house with 3-4 bedrooms (100 litres). 

For open vented systems you will need to add the fluid via the feed and expansion tank. For sealed systems you add the fluid via the radiator using a Fernox Injector. In single feed indirect cylinders, e.g. "Primatic" or similar, potable water chemicals must be used.

For continued protection Fernox F1 Protector levels should be checked regularly (annually). We recommend untreated or sludged systems are thoroughly cleansed and flushed in accordance with BS7593 and Benchmark using Fernox Cleaner F3/F5, before treating with Fernox Protector F1, as existing debris can damage the installation.
