A very common heating myth is that it takes more energy to turn the heating on and off, than it does to leave the heating turned on at a low temperature constantly. According to experts at the Energy Saving Trust, having the heating on only when you need it is the best way to save energy and money.
One reason for this is that a small amount of energy constantly leaks out of your home, so if you keep the heating on, you’ll be continuously losing energy all day.
Why put your heating on when your not in the house to benefit from it? Make use of your timers so your heating only comes on at the times of day that it’s needed. Make sure the clock on your timer is right and remember to adjust it when the clocks change.
