My heating puts itself on. It’s thermostat controlled and I never switch that off. I don’t care what the date is, if it’s cold I want the heating on. It clicked on this morning for a bit. It’s set to come on for a couple of hours in the morning and all evening if the temp in the living room drops below 19, so not extravagant. I had it set at 18 last year but that was a bit miserable.
