If you leave your heat at the same temperature all day and night, you’re missing out on some serious energy savings.
There’s no need to keep your home toasty warm while nobody’s in it—like during the day if everyone leaves for work and school. And you’re wrapped up tight in a comfy blanket overnight, so it stands to reason that you’ll be perfectly comfortable sleeping in a home that’s a bit cooler than it is before bedtime.
Your best bet: Invest in a programmable thermostat that will automatically turn the heat down when you leave for work; up when you’re due to get home; down again right after you go to bed; and up again a half-hour before your alarm wakes you up in the morning.
The U.S. Department of Energy estimates that you can save up to 10 percent a year on heating and cooling if you turn your thermostat back seven to 10 degrees for eight hours a day.
