If you’ve read our Home Heating Economy Tips you’ll know we recommend you consider running the heating continuously.
This applies principally to frequently used rooms during cold weather. It means that if you turn the thermostat down when you are not in the room rather than switch it off, reaction time is fast when you next use the room.
But for occasionally used rooms the answer is “no, switch the heating off when the room is not in use”.
As a footnote, you’ll be interested to learn that the thermostat works by switching the heating on and off to maintain the thermostat room temperature (set point temperature). This means the heaters are typically operating no more than about one third of the time – even when you think they are fully on!
