Protector F1 is the market leading inhibitor which protects against corrosion and limescale formation in domestic central heating systems. Protector F1 is suitable for use with all metals and materials commonly used in heating systems. For long-term protection ensure concentration levels are maintained and checked annually as part of the boiler or system service. Protector F1 is compatible with all other Fernox products.

The recommended ‘in use’ concentration of the product is 0.5%. One 500ml bottle will treat an average 3 to 4 bedroom house (100 litres). For open vented systems add via the feed and expansion tank. For sealed systems add 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 Protector F1 levels should be checked regularly (annually).

Great website. Very quick delivery. A very positive description.
Great product, great service. What more can I say.
My heating programmer went U/S AFTER 10 years, that replaced after original installed 36 years ago. My heating engineer tried his suppliers that it could not be obtained but took about 3weeks to tell him. Said would need latest programmer with additional wiring. Could be costly. My electrician man located correct replacement, Delivered to door in 48hrs. Job done same day. House warm again. EXCELLENT SERVICE. SUGGEST USE WITH CONFIDENCE
