Timer Firing Up Boiler for Water, not for Heating

[Mark Walsham]

Hi everyone,

I have a Climote (but re-badged by Scottish Electric) timer, which I think has developed a fault, and need some advice as I have a problem.

First off, I have a Valiant traditional boiler, pressure good, power good and regular servicing. I note that when I ask the Climote for HW, the boiler fires up, lights and starts to heat the water.

If I try the same for Heating, and the Climote says it is on, but nothing happens on the boiler at all.

I have checked the external thermostat, and it is reporting 10dg lower temp than the target temp - so I don't think it is that.

Any ideas what this might be. Have reset the timer, checked the boiler pressure and power and all seems good.

Appreciate any thoughts or ideas.

Cheers, Mark.

Looking at the location of the valve I would say it looks awkward. I would get someone in to change it for you.
