I have a open pumped CH/Gravity HW system. I need to refill with inhibitor,
but am confused if which I should use.
Fernox produce MB1 and F1 but it is not clear what the
advantages/disadvantages of each are? Alternativly I have looked at Screwfix
No Nonsense range.
The house is a 4 bed, with 11 rads. How much inhibitor should I be using? I
am guess at 1 bottle of MB1/F2, or using 2 for screwfix.
What is the consensus on which inhibitor to use here?
