## Customer Reviews

### ⭐⭐⭐⭐⭐ Preventative maintenance.
*by A***T on 12 June 2025*

Used Fernox inhibitor previously and this time cleaned central heating system with a double dose of Fernox F3 and refilled with Fernox F1. It provides peace of mind that the pipework remains in good condition for many more winters.

### ⭐⭐⭐⭐⭐ Fernox with a long established pedigree.
*by D***S on 28 November 2024*

Following our Vaillant boiler service, the ph was still too high even though I had added an alternative brand enough to treat 400 lts a few months before which had really quietened both the boiler and the pump right down. The engineer strongly suggested using Fernox F1 enough to treat 130lts which is a 500ml bottle which was £20 on Amazon provided you look carefully through the purchase options.I have used Fernox over many many years, but this time round I purchased on price as I got 2 alternatives which did 400lts for the same price as the Fernox for 130lts. The next service will see if there is a difference. I suspect there will be when Fernox lives up to its pedigree.

### ⭐⭐⭐⭐⭐ Keep your system clean
*by C***W on 21 July 2024*

Use it every year, works for us.
