FernoxF1 epress is very good as well you can dose it into the filling loop

both aerosol and cartridge types can be dosed into filling looops as it the least messiest.its recomended to keep your inhibitor topped up every couple of years.

if you have problems with rads heating etc you can addd cleanser first

This is a cdi guys, unless somebody fitted an extra universal filling loop, you're gonna need some towels if you want to use the WB filling loop.


OP, how do you top the boiler pressure up?

 

[Tiredeyes]

with a white plastic key thing you shove the bottom end of boiler and the lickle plastic screw to let water in.
I found the outside drain tap and let all the water out today, there is no sludge and the water runs clear, but no inhibitor in wot so ever.
I filled up system, and bled bottom rads first, then upper floor, finishing in loft conversion, our bedroom rad is sweet now, whatever was stopping our rad is out or moved !
but all rads are red hot now.
I guess it wont hurt adding fernox now, after 8 years with non in?

Water coming out clean does not mean a lot, but better than black gunge I suppose.
Adding inhibitor stops corrosion forming, so adding it at any point is better than not.

Add the inhibitor via a radiator as you can't do it via a WB filling loop as said.
