My Central Heating suddenly stopped working. However, the hot water is fine.
When I turn the Hot Water ON through the Programmer / Timer (say constant), the boiler immediately fires.
However, when I do the same for Central Heating, it doesn’t fire the Boiler (the Pilot is ON).
I have replaced the Programmer / Timer, but it doesn’t help.
Can the problem be with the Room Thermostat (it makes the clicking sound though, when turned) or is it the Boiler ?
