As recommended by heating engineer. This inhibitor should help prevent rusting of my central heating system. Item was readily available for collection from Toolstation.

These Adey product are really good. I have a 20 year old system. I used the system cleaner then added this protector. The system seems to stay clean as a year later the water was mainly clear when drained to renew a radiator. The boiler was noticeably quieter too.

The product is great. Took Toolstation 3 attempts at delivering it. They kept sending Corgi Inhibitor which is cheaper and isn’t what I bought. Each time it took an hour on their webchat to try and resolve. This is the first time they messed ip with a delvery, but they did it so thoroughly!

Hazmat101 Verified Purchase

With a bit of inventiveness, we managed to add the necessary amount to the radiator concerned. It is the same chemical that was already in the system so shouldn't cause any bad reactions.
Sourcing it locally was a bit of a game and thank you Toolstation for stocking it.
