Hi,
my hot water is heating up when the CH only is switched on. It is a 2 port 2 zone with loft header and HW water tank in the airing cupboard.
The HW zone valve actuator is running ok though a little stiff at the end when it closes. So I removed it and made sure the valve spindle is fully in the closed position. It appears the HW is still heating.
How often do the valve bodies fail and allow hot water to pass, which is what I am suspecting now as the pipe on the other side feeding into the tank is hot.
Thanks
Dave
