Hello all - first poster here!
We've had issues with our central heating for a while. Basically, it 'sticks' in the on position and doesn't turn off. Previously we would turn the system off, and leave it over night and some how it would come unstuck, but recently this trick has stopped working. It's on all the time!
So we called out a plumber and he told us that the zone valve actuator had gone. It would need replacing.
I asked what this entailed / how much and he did the whole 'tut' and shaky head thing. Would require draining the entire system - 4 hours + parts £500.
There was just something about the way he said it that made me want to double check. I noted down the make of Zone valve (Drayton ZA5) and all of a sudden I found quite a few posts online that seemed to suggest that with this type of actuator - it's simply a matter of flicking a lock and a button and off it comes. No need to do a full drain.
I don't know how long it takes to wire one of these things in but from the diagrams it looks pretty much like a few wires and a screw driver. 30 minutes tops.
So - am I barking up the wrong tree - or is my plumber telling me big fat porkies!?!?
