Fernox F3

[Luis21x]

Hi,
I am planning on descaling my Range Powermax 185 boiler, as it makes a lot of noise when on especially first thing in the mornings. How do I effectively carry this out with Fernox for example ? Do you apply it in via the radiators ?

Also, how long do I leave it in there for before draining the tank out ?

Thanks,

Turn off rad both sides. Drain water...add in F3. you will need at least a double dose as thats alot of water in that there powermax....


As for time scales.....read the instructions!!!
