I have bled my radiators, however the bar has dropped now from 1.5 to to 0 on the boiler. There are no instructions in the operating maual for re-filling the tank. I think the rads may still need bleeding, but since the bar dropped, no more air or water is coming out. Perhaps when the bar is raised I can re-bleed them till water appears?

Many thanks.

use the filling loop under the boiler.connects from 15mm cold rising mains to the 22mm return central heating pipes.As you say once bar pressure is built up you will be able to bleed rads again
