Hey,
Smoking and burning smell traced to this actuator as it tried to operate.
On closer inspection, water inside the actuator body and the valve stem is soaking wet. Also covered in crud.
Excercised the valve with the actuator off and the stem sheared away!!
So - I’m thinking replace the valve and the actuator since water ingress to cabling and motor probably doesn’t bode well.
Not familiar with this heating system, only had a combo and an unvented system previously.
Do I isolate from the loft tank, and then drain down?
thanks!!!
