i do apologise, the pipe on top of the cylinder without the valve comes from the 3 way valve and gets hot, the other one with the valve goes through the floor.

Hot water not working

i would say it blocked or airlocked.
trouble with that valve aswell is that it has a small internal bore and will restrict the flow.

ok, i will try and find air block. i understand the new valve does need replacing it was a needs must situation, however the ch is working fine, it is the hw that is not.
i would put some towels around the top of the cylinder.
shut that valve.
slacken the nut under the valve and let the water trickle out
that'll prove its not blocked and should clear any air.

apart from at the top of the 2 x 15 mm copper pipe is there a way to bleed the cylinder?
The CH will be working fine if that valve is at fault.
From I've seen/read, it looks as if the valve is either blocked or restricting the flow through your coil. The upshot of this would be no hot water.

you say you have two air vents.
if you have one on each pipe.
shut the 3 port valve to hw so its on heating only and open the bleed valve near the 3 port valve then it will pull water from the other direction
through the cylinder to the air vent and should release any air.

when i do that with the towels the water howls out, which means i have to empty the system down to undo nut.
this sounds like a good idea however I do not know what position the lever should be in, I have just moved it from one side to the other and then the middle and did not know what for.
lever in the middle will be open
lever turned either way should be shut.

just cracked the bleed nipple in the 15 mm pipe so cant try anything else until tom but thank you all very much.
