I discovered that my water wasn't heating when I took a shower and froze.
Not a huge problem a.t.m. as I can use the immersion. Boiler fires up fine when CH prog selected.
I thought it would be a zone valve, confirmed in FAQ, but I've got 2 (Honeywell V4043H1056) - 1 close to the h/w cylinder and one further away.
I switched them both to the manual position & still h/w not calling for heat.
When I turn the CH on, the valve furthest from the cylinder moves its switch but the one near the cylinder doesn't do anything. Is this one f***ed?
If so, do I just remove the single screw in the galvanised cover to access the workings?
Thanks,
