Dear All,
Can anyone explain why a new towel rail will only fill about half way up on a gravity fed, fully pumped, vented ch system. I thought that any item in the system that was lower down than the f&e tank would naturally fill due to gravity.... towel rail is on the top floor, f&e is in the attic, about 1.5 metres above the top of the rail..... Its got me confused as some of the rad's downstairs are also reluctant to fill.... In the end, I've only managed to fill the system by pouring water into the towel rail...
