help, my gloworm combi boiler is heating my water but not heating the

i have bled all rads incase air lock but from the middle floor to top

ideas?

The system has no pressure if there's nothing coming out of the rads.


If there is no pressure, there will be no hot water either.
Another poster says the header tank needs filling! Why even reply if you
havent got any idea about these things?

Because the fauklt description fits that scenario perfectly.

I think the point he is making is that combi boilers don't have header
tanks, they are closed, pressurised systems with an air-filled expansion
tank.
