Ive got to take a second look at a thermal store this afternoon that's connected to a gas boiler and the problem is that the heating won't come one unless the water is on as well, when the heating reaches temperature the water heating isn't working - or so I've been told They can't get enough hot water to have two showers in a row.
I've tried changing the old Potterton EP2002 programmer for a new Drayton LP722, which should cause the HW to run independently of the CH but it isn't.
I know that theres a 2 port on the heating side but no other valves sooooo.... does anyone have a wiring diagramme that I could use to help diagnose this?
Cheers
