When the room is heated up again the comfortableness is diminished by the walls which are cooled down. So if one wants a real comfortable room temperature the regulator must be turned up and so a lot more energy is used up than is in case of an even heat supply. If the building has good thermal insulation it is possible that the set economic temperature is not reached. [. . . ]
