We don't have central heating, but do have a set routine of heating rooms in a sequence...electric fan in the bathroom while we shower and dress, electric ceramic panel in the kitchen while we breakfast, then gas fire in the living room if we are staying at home. OH feels the cold, but will happily sit watching TV with a blanket over his legs, a hot water bottle, mittens on his hands and a hat on his head. The hat is the key element; without it he complains constantly, even when the temperature is in the 20s. I can't stand the heat in there because I am dressed for the ambient temperature in the rest of the house as I potter. Half an hour before he goes to bed (at 9pm) I put the heater on in the bedroom, and once he is in bed with a fresh hot water bottle, I turn it off. I also turn off the heating in the living room and then settle down with the blanket and my hot water bottle to watch my choice of TV.
