I had my CH changed to a sealed system with new boiler several months ago. I've noticed that one of the bathroom towel rails needs bled from time to time (top bar doesn't heat). When I bleed it the pressure drops by around 0.1 bar but if I leave it without bleeding the pressure stays up. So I'm puzzled - how can air get into the pressurised system whilst leaving the pressure unaffected?
This particular rail has always needed bled from time to time when I had the open header tank but I had expected it to stop when it was sealed.
On the offchance that it was hydrogen being generated I tried lighting it but no result. The system has plenty of new inhibitor in it.
