The strategies below will help you save energy, save money, and stay comfortable during the cool fall and cold winter months. Some of the tips below are free and can be used on a daily basis to increase your savings; others are simple and inexpensive actions you can take to ensure maximum savings through the winter.
Open curtains on your south-facing windows during the day to allow sunlight to naturally heat your home, and close them at night to reduce the chill you may feel from cold windows.
Use a heavy-duty, clear plastic sheet on a frame or tape clear plastic film to the inside of your window frames during the cold winter months. Make sure the plastic is sealed tightly to the frame to help reduce infiltration.
When you are home and awake, set your thermostat as low as is comfortable.
When you are asleep or out of the house, turn your thermostat back 10° to 15° for eight hours and save around 10% a year on your heating and cooling bills. A smart or programmable thermostat can make it easy to set back your temperature.
Seal the air leaks around utility cut-throughs for pipes, gaps around chimneys and recessed lights in insulated ceilings, and unfinished spaces behind cupboards and closets.
Wood- and Pellet-Burning Heaters: Clean the flue vent regularly and clean the inside of the appliance with a wire brush periodically to ensure that your home is heated efficiently.
Keep your fireplace damper closed unless a fire is burning. Keeping the damper open is like keeping a window wide open during the winter; it allows warm air to go right up the chimney.
If you never use your fireplace, plug and seal the chimney flue. If you do use the fireplace, install tempered glass doors and a heat-air exchange system that blows warmed air back into the room.
Turn down the temperature of your water heater to the warm setting (120°F). You’ll not only save energy, you’ll avoid scalding your hands.
