Recently there have been a few occasions where the HW has been working just fine but there has been a considerable delay (1 to 2 hours) before the radiators starting to heat up, despite everything being set for them to come on immediately.
Today the radiators did not come on at all (but HW OK). We have a wireless thermostat with the receiver in the airing cupboard. The receiver indicated the heating was on but looking at the actuator it was set to HW and I could not move it. I decided to unscrew the single screw securing the actuator lid, as I was doing this the actuator switch suddenly moved across to the CH position and I could tell the radiators were heating up (so I simply retightened the lid).
The boiler, pump, wireless thermostat and receiver were installed about 5 years ago (not sure about actuator) and the system has been working fine. The actuator is a mid position actuator BGMVSP-23.
My questions are:-
1) I'm assuming that the issue is with the actuator sticking somewhere. Does that sound reasonable?
2) Are there any temporary work arounds to make sure the CH will always work until I get time to investigate over next couple of weeks e.g.
a) Some manual way of overriding the actuator when it fails (didn't feel like I could force the switch over)?
b) Adjusting HW / CH times so actuator never goes to HW only position
I am not particularly proficient with electrics or plumbing, and have only picked up the above knowledge purely from these forums.
Thanks in advance.
