Hi, I have this rather ancient gravity/pumped CH system, using a Baxi Bermuda LFE5 Super back boiler operated through a room stat. No stat on the (indirect) HW tank.
Question: The CH works, but doesn't heat the water in the tank at the same time. Can anyone please explain why?
The controller is a Drayton Tempus with the Boiler and the Pump wired together via the timer and room stat.
Yesterday I disconnected the Pump wire and switched on, and the pipes to the coil heated up, so I guess there's no blockage.
Is the pump nicking all the water for the rads?
I'm sure it used to work!
Any help would be greatly appreciated.
