Most of you are probably familiar with the timers on central heating systems but it's hurting my head.

In a nutshell, there's no heat coming off the central heating and we think it's something to do with the timer. I'll attach a photo that was taken at around 6:10 pm this evening. Obviously the actual time on its wrong but I've corrected it and there's still no heat.

If anyone can tell me what I'm doing wrong, much appreciated.

PS - apologies in advance for how dirty the timer looks. Not something to be posted at dinner time but look, I'm cold. Thanks.

Timers on room stat got voltage ?
Well the light comes on and it makes a noise. Whether that means voltage or not I'm not entirely sure, but it was working fine up until last week, even if the timer on it was all over the place somehow.
 
As far as I can see from the photo, the timer is set to be 'on' between 0415 and 0700hrs, which makes it likely that it is controlling the hot water cylinder, assuming you have one. It also looks to me as though it has been set to 'always on' rather than 'time-controlled'. There is a white lever/paddle with a '1' at one end its travel and a clock face at the other that controls this.

So, for the avoidance of doubt, do you have a hot water cylinder and is the water in it hot? If I'm right, you need to move the paddle to timed mode and set the correct time.

What sort of thermostat controls the central heating? (Take a photo if you are not sure.) Are there any other time switches around, e.g. on the boiler itself? What make and model of boiler do you have?

What do you mean by "Well the light comes on and it makes a noise." Where is this light. Where is the noise coming from and what does it sound like?
