Get Big Savings on Your Heating Bill With These Simple Lifestyle Changes

The Energy Department recommends turning thermostats down 7° F to 10° F when you’re not at home and at bedtime to save up to 10 percent ($90) per year on an average heating bill. And consider a smart thermostat. “A smart thermostat can automatically adjust to your habits and changing weather via sensors,” says Rebecca Foster, CEO of VEIC, which administers energy efficiency programs, “so it does the work of optimizing performance for you.” These typically cost $100 to $300 but can save you another 8 percent on heating and cooling bills per year. As for your water heater, lowering it from 140° to 120° F and cutting 8-minute showers in half could save $168 a year.

CR’s Top-Rated Smart Thermostats
These top-rated thermostats let you control your home’s heat remotely and can learn your preferences as well as whether you’re home or away and set the temperature accordingly.

“I love a crackling fireplace,” says Larry Zarker, CEO of the Building Performance Institute Inc., a nonprofit credentialing and standard-setting organization for the industry. But unless it’s properly maintained and used, a fireplace can send heating dollars up the chimney. (And because wood smoke can pose health risks, you may want to use fireplaces only occasionally.)

Have your chimney inspected and cleaned yearly, and use a fireplace screen to contain sparks. Close the damper between uses, and consider a chimney liner as well as tempered glass doors and a fireplace heat exchanger, which warms the air and sends it back into the room. Another idea: Apply sealant and weather stripping around the chimney to reduce air leakage by 14 percent or more. If you’re not firing up your fireplace at all, a fireplace plug (about $60) may be wise.

Insulated cellular shades and thermal curtains can cut the amount of heat you lose through windows by 40 percent or more. Hang curtains close to the panes and let them drop to the floor or windowsill to further block drafts. Keep shades up and curtains open during the day to capture heat from the sun.

Reverse the rotation of your ceiling fan so that it turns clockwise. This helps to push any warm air that has risen to the ceiling down toward you.

Done making dinner? Turn off the oven but leave its door open, says Christine Ciavardini of MD Energy Advisors, and let the residual heat warm up your home. You’ve paid for it. (While leaving the door open with the oven off is not harmful, CR strongly advises you to never use your oven for heat by leaving it on with the door open. Read "The Dangers of Using Your Gas Range or Oven for Heat" for more details.)

Flannel sheets have fluffy, raised fibers that become heat-trapping pockets. Top them with a wool, fleece, down, or down-alternative blanket, and run a hot-water bottle or soapstone bed warmer ($47.50 to $57.50 from the Vermont Soapstone Co.) between the sheets before climbing in.

Instead of turning up the thermostat when you feel a chill, dress in layers you can put on and take off as needed. Start with a close-fitting top and bottom of performance material (think workout wear or long underwear), which helps lock in body heat, add fleece-lined slipper socks, and top with a wool sweater or fleece-lined sweatshirt.
