Review for Fernox Protector F1 500ml by DAJ
20th September 2023
A good system inhibitor, combines with other mitigations it will help prolong the life of the heating system.
Always have some to hand, never sure on previous brands but it’s a common one to be used.

Good quality inhibitor, can treat upto 130 litres.
As with any inhibitor it’s best to not mix brands and add to a clean system. If you’ve got dirty water currently, just adding an inhibitor is not really going to solve all your problem.

Have used this product for decades & always had wet heating systems protected.
Surprised some local heating installers fail to add this to the new systems as I have seen younger systems than ours rusting from the inside.

Love Fernox products and these chemicals. I have used this inhibitor for many years and have always been pleased with the results. Many other inhibitors have come and gone but Fernox has stood the test of time.

Mainly use this as I trust the brand. Always had good experiences with fernox. Costs a little more than the cheaper centre brands own stuff but well worth it

It is the standard, can't go wrong with fernox products. There are cheaper products but these guys have been the standard for decades and why would you risk it?
