My central heating and water is controlled by Potterton EP2002, so they can be switched on independently of each other. Recently the hot water has stopped heating, but the central heating is still fine. I reset the EP2002 just in case that had thrown a wobbly, but it seems fine. I see there is a Myson Compact CP53, could this be the culprit? I'm also struggling to work out what all the pipes are in my airing cupboard and where they go to. When I turn on the central heating plenty of pipes get hot, but not the pair connected to the CP53. There are also two valve actuators, one of which clearly turns on when the hot water is turned on by the EP2002.
We're currently using the immersion heater for the water. However, I would like to have the water go cold so I can check things a bit more. However, SWMBO can't go without her hot water for more than a few minutes, so I'm a little stuck!
