Just something I put that wasn’t relevant. Anyway, the pipe going into the cylinder from the 3 pot valve is that hot?
We have hot water!!!!!! No idea how or why I turned the immersion on, every outlet turned on full, didn't see or notice any spluttering from the pipe, then did the mixer tap trick with everything open

but then sudden warm water!!! However the tank is now very noisy? Attached a video.
The water pressure is also very poor but I'm not sure if that is due to more air locks or just the norm for a gravity fed system.
Thanks again for your patience and help
