Hi,
My central heating system is starting up but only running intermittently and not for long enough to heat the house. It improves slightly if we run the hot water taps for a while.
This started recently with the sub-zero temperatures and the most noticable change is in the zone actuator. It's cycle is much quicker and louder than before, and is trying to click from A to B every 15 seconds, but doesn't get to B then starts again.
Could this be what's stopping the heating from running consistently?
