central heating inhibitor (what brand do you use)

[paul78]

As the tiltle shows im interested to see what type of inhibitor is best, i know opinions vary but is there much difference in the no nonsense brand or the sentinel or fernox brands as the prices are not much difference anyway.

Id rather get the best one for the job.

Plus how much would you use in a combi system with 8 rads running of it.

thanks

Fernox F1 concentrate for me - the tube comes with a kit that allows you to inject into the system either via the rads or the filling loop.
One tube is fine so long as the system is clean, but overdosing isn't a problem.
Avoid the no nonsense stuff.

thats what i was thinking or the MB-1 but that comes in 4 litres.

The no nonsense stuff is a fraction of the price but i look at it like putting oil in the van, buy cheapo stuff then pay twice.

Plus when your charging customers id rather use quality stuff so less chance of call backs that cost £££'s

interseted to see what the majority vote is though
