We have a Volkera Linea boiler with a mechanical clock which we have set to only come "on" in the mornings. However, my radiator will heat up in the evenings as well and when I go to look at the boiler I can see it lighting up. I am fairly confident that we have set it up right. Why might this be happening?

Hi
I have a baxi duo tech boiler and when the central heating is off still on the boiler central heating light is there an the radiators are hot as well. Is there a problem in the boiler or is it normal.
