Problem Hot Water not getting hot

[Plog1976]

Thanks for all your help on this. Got plumber coming today will mention about tanks in loft as nobody checked there yet

Nothing to do with pressure in taps, you have 2 x tanks in loft the small one keeps heating & hot water pipes toped up with water, if small tank runs dry water level in pipes will drop causing problems with circulation if you are able to access loft just check that small tank has water in it , if not ball valve will be stuck , sometimes just moving it up & down will free it up, if not you will need a new ball valve.

Not the big tank No need to bother about that one, that is supplying water to your hot water tank, should be a small tank close by, maybe higher up than the big tank, are you able to get into the loft ? or don't you want to risk it ? (Age maybe)
Can you manage a photo of loft ? No video attached !!!

Think that is the gate valve for the hot water supply to the taps

I'd wait and borrow a decent set of steps and a head torch so once you're up there you can have a poke around but still have both hands free to support yourself, if in any doubt then don't go up there and wait for the plumber, not worth having an accident
