Excellent Stuff
11 Dec 2015
By
, Aylesbury
" I've always used this stuff and it seems to work well - limiting scum in the system.
I'm renovating a house - slowly - and use this on a regular basis as I have to drain and then top up the system after doing each room. Screwfix prices are normally pretty good so I add it onto the order - along with one of their radiators and a nice shiny Drayton TRV4 "

It works!
24 Oct 2015
By
, Lightwater
" Fernox gives real confidence. It does all expected.
Always used Fernox products, recently needed to drain partially to fit a new valve.
No evidence of sediment. I topped up with the F1 and several weeks later the heating is working perfectly. Fast warm up, all radiators even heat, no trapped air. "

" I had to drain the heating system and so needed to add an inhibitor when refilling. Fernox F1 has a good reputation and I've used it before, although not usually the cheapest option. Great to be able to get it at Screwfix on a Saturday afternoon, when all the plumbers merchants had closed for business. "

" We often go back to a system after years of 'benign neglect' to find everything working well and still a high inhibitor value reading.
Well worth the slightly extra costs - excellent value right across the range of products.

I wouldn't use anything else
20 Sep 2014
By
, Scunthorpe
" Last year I flushed my system using F3. I then refilled it and used F1. Just recently I needed to change a large radiator for a smaller one in the kitchen. Due to kitchen refurbishment nothing to do with problems with the heating system. On draining the system I was amazed to find that the water coming out of the drain tap was all but clear. So guess what I put back in? I wouldn't use anything else. Also it's guaranteed for 10 years, what more could you want. "

" -but why don't Fernox fit a cap that a tube can be affixed as presently it is difficult to pour into a radiator. It would then be a 5* product with even higher sales. "
