Hi,
This is my first post here. I did try searching the forum, but could only find references to old systems so sorry if this has been covered already.
I've recently had a completely new central heating system installed (all new pipes, rads and boiler). After one month of operation, I removed one of the radiators and was surprised to see some black crud (magnettite?) coming out when I drained it. Is this normal in such a new system?
I know the system was cold flushed and that inhibitor was added when installed. I've also noticed that some of the rads were cold at the bottom so could it be that air in the system contributed to the rads corroding already?
Thanks![/img]
