glow worm 30 cxi - hot water works fine but when i run the heating it seems like the boiler is full of air, it gets up to temp far too fast and shuts down. i have tried all the obvious things like bleeding rads and turning them off 1 by 1 but it just will not shift. boiler is fitted downstairs and piped correctly fairly new system on 15mm and 22mm so doubt its a blockage. pump is spinning correctly.
heard bad things about these boilers and i would never fit one. its driving me crazy.
any ideas?
