Should the pipe from the top of the Water Cylinder be hot rather than warm

[king of pipes]

It is possible to lock the valve open manually to try it's operation if you take a look ?

Just experimented and it moves from left to right when hot water turned off, but then when you turn it on, it doesn't move back again and it does seem to be getting stuck on that right hand side where it is much stiffer, so I think even though it is pretty new it is that valve which has gone

Thanks for all your help KOP

I will turn hot water on now again and move left myself and leave for 30 mins and see if water hotter

Hi KOP, thanks for looking, pictures below View attachment 60610View attachment 60611

Even though the two coil heating pipes are "roasting", might be no harm to check the position of the manual valve with the red handwheel, it should take ~ 4 to 5 full turns to open or shut it, shut it fully, then reopen it fully, shut it fully (again) then reopen it ~ 1 to 2 full turns or if it was fully open originally return it to this position, the coil should heat the cylinder, depending on its volume, in 15 to 45 minutes so 1 hour should definitely heat it except programme time too short or cylinder stat set too low or faulty. If heating it with one electric immersion can take a few hours, depending on cylinder volume.

Thank you John, will give that a try as well
