Re: Central Heating but no hot water
it's almost certainly air just go up into the loft and make sure the header tank is full of water, the ball valve could have stuck shut,another trick is to blow down the open vent pipe which is the one looping over the top of the header tank,you could dip your hand in the tank and just make sure there's nothing blocking the cold feed from the header.
