Put your Central Heating System question in here.

Hi

Hope you can advise. My heating is coming on when the hot water’s on, with the CH controller switched off. I understand that this is a common problem, I thought changing the motor in the two port valve would do it, but it hasn’t.

The problem appears to be that the spindle only lines up with the valve connection so that the lever on top of the actuator sits at half way across between manual and auto, rather than fully across at the ‘auto’ end. Thereby leaving the valve open. Hope that makes sense? Any suggestions how to fix?

Thanks
Nick
