Now that I have the payment for the replacement Fernox in my central heating system any words of wisdom would be appreciated before I start the job.
Is Fernox MB-1 a sensible choice?
I intend draining down and doing some sort of flush and have thought of back flushing the system with mains water. I have found three drain points, one by the boiler and another at each end of the house.
Are flushing additives worth considering?
It's an open vented system with header tank in the loft from a Mexico HE36 condensing boiler feeding 10 double panel and 5 single radiators, 3 large towel rails and 1 kickspace heater.
