When using your fireplace, turn down your heater. When you're not using it, close the damper to block incoming cold air.
Close curtains, shades and blinds at night and during unoccupied periods of the day to help prevent warm air from escaping.
Set your furnace thermostat to 68 degrees Fahrenheit (68 F) or lower, health permitting. Three to five percent more energy is used for each degree you set your furnace above 68 F.
When you leave the house, set your thermostat to 56 F. By turning your thermostat back 10 to 15 degrees for eight hours, you can save five to 15 percent a year on your heating bill.
