Hi, can anyone help?
I hve recently had to drain the system completely, twice, to have a radiator replaced, but I'm hoping this is incidental to the problem.
Gledhill thermal store - but that's irrelevant really. Hot water is fine (valve in the non-actuated position.) Central heating only gives a tiny amount of warmth on the rads (not hot at all) even though the store is well up to temp.
If I put light pressure on the lever on the valve acuator, even when the heating is called, it has not moved very much at all. If I manually push the lever to the central position, the rads get piping hot. The room stat is satisfied, the valve actuator returns under spring pressure, but when the room stat calls again, the same problem occurs.
The valve body (not the actuator) was changed earlier this year. I have taken the actuator off, and the valve spindle is easily and smoothly rotated with finger, so I assumed the actuator was duff. However, with the actuator NOT on the valve body, the actuator operates exactly as it should! This confuses me, as I say, the valve spindle itself on the body of the valve can be rotated with light finger pressure....
Is it possible for an actuator to become weak or am I barking up the wrong tree?
Thanks in advance,
-m.
