Rated 5 out of 5 by from Superb product Changing the first of my radiators I flushed the old system with F3 and added F1 when I refilled for 6 months of over winter use. Ive just drained the system off (to add 3 more rads) and the water was clear and clean with zero rust particles or debris.

Rated 5 out of 5 by from Trusted Brand Fernox F1 heating protector, Leading brand heating system protector. Simple to add to the system through Fernox compact filter unit without the need to re pressure the system with only a 500ml exchange. Slightly more expensive than other brands.

I have removed a radiator whilst decorating and flushed it to clean any debris. Can I add the Fernox directly to the radiator via the bleed valve after I have reconnected as having emptied the radiator I would be just diluting the system if bleed to fill.

Asked by: RAM1960
Hi Ram1960, yes no problem at all with doing this
