Keep the heat inside by closing draperies at night. During the day, open them up to let the sun shine through and warm your home. You can also cut heat loss by caulking and weather stripping doors and windows.
Avoid overheating by setting the temperature as low as you can and still be comfortable. For every degree you lower the setting for an eight-hour period, you’ll save one percent on your energy bill. Using a programmable thermostat can save you even more money. Set it to lower the temperature at night and when no one is home.
Check the filters in your furnace at least once a month. This will improve the efficiency of your existing furnace.
Close the damper on your fireplace when not in use to prevent heat from escaping out the chimney.
Use ventilating fans only as needed. Venting fans in bathrooms or above stoves can blow away a house full of warmed air in just one hour. Turn them off as soon as the room is cleared.
Up to 20 percent of your heating energy can be lost through a ceiling that is not well insulated. Ensure that your home has proper insulation to keep your home warm in the winter and cool in the summer.
