I then wondered if there is 'air' in the system or some leak? I've bled
all the radiators and thats was all ok. Checked the header tank and
plenty of water in there.


Have you bled the air from the system bleed valve too? usually it'll be
near the pump, valve, etc (in the airing cupboard) and will be a length of
copper pipe sticking up out of the system with a bleed valve on top. It'll
be higher than the pump, valve and coil.
