Keeping combi boiler system clean

Post by hiace_drifter »

I have a combi boiler and about 10 rads. I'd like to keep it clean to improve efficiency and increase lifespan. I bought a bottle of cleaner (fernox) and their advice is to insert cleaner, run for a day, empty system then 3 x refill/run for a day/empty. This is to ensure no cleaner is left in the system.

It seems a lot of work, but maybe I'm being naïve! Is there any easier way - e.g. the inline filters like Adey magnaclean, or fernox TF1? Or do they all need chemicals/multiple flushes too?

Thanks.

Chemicals in the system do what ever they are supposed to. In my case I have fernox protector f1, it stays there all the time. A magnaclean or similar sits there grabbing ferrous oxide particles as they pass (Rust to you and me) I have a magnetic cleaner too, i had to cut the pipework to install it, that way I can empty it once a year (Its always clear now)

I put my f1 in by opening my magnetic cleaner to let the pressure down, then took out the bleed valve of the highest rad and put in the f1
So I am told you can also remove your magnetic filter put the chemical in that and put it back.

In either case you must repressurise the system.

Would you hit a nail with a shoe because you don't have a hammer? of course not, then why work on anything electrical without a means of testing Click Here to buy a "tester" just because it works, does NOT mean it is safe.

I was thinking more of the cleaners that get added then removed, rather than left in (like inhibitor). E.g. fernox f3 cleaner needs to be rinsed through 3-4 times. I wonder if the inline filter removes need for cleaning through (both before and after).
