I've been slowly replacing all the rads in my house, last week I replaced another 3 and took the opportunity whilst drained down to fit a Magnaclean too. I'm running Fernox F3 cleaner through it for a week and will drain down again this weekend to put in Fernox F1 Inhibitor. The highest rad (towel rail) has always needed bleeding every couple of days as the top rung is only luke warm so I'm wondering if putting a something like Fernox F4 leak sealer might solve this or am I better of fitting an automatic air valve? Boiler is and old worcester danesmoor 12/14,unvented system.
Oh and as a side note I had to drain down 12 hours after fitting the magnaclean last weekend and took the opportunity to see how much it had collected.............loads of gunk after just 12 hrs, I'm well impressed
