glow worm boiler no hot water?

open all hot taps, cross link a cold water main into the hot pipework and open for a few seconds, that should shift it, best place is often a kitchen where you will have hot and cold washing machine taps, ideal has you have the 2 feeds close together and isolators in situe, perfect!
