Hi folks,
My boiler is firing up at several points throughout the day and night. CH is switched off (as you'd expect - it's July), and HW is scheduled once a day, in the morning.
I've noticed the sound of a pump running in my downstairs WC, which is where all the (boxed-in) pipework from the boiler heads off to radiators and HW cylinder.
My theory is that either the pump is stuck open and that's causing the boiler to fire up to give it hot water, or that the controller has some sort of problem that's causing it to kick in even though the HW cycle is not active.
Any other ideas? Any thoughts on how to diagnose?
