Use the sun for free heat. That bright orb in the sky should be the focus of temperature control in your residence throughout the year. Open the curtains on your south-facing windows during winter days to bring free heat into your home. Close your window coverings when the sun goes down to keep the heat inside.
Bundle up with warm accessories. This is one of the easiest ways to save on your heating bill. Instead of turning the heat up, put on a cozy winter sweater and warm socks. Keep throw blankets on your couch, and add an area rug to insulate the floor.
Adjust the thermostat at night. According to the U.S. Department of Energy, you can save about 10 percent per year on your heating bills by turning your thermostat down 10 to 15 degrees for eight hours. Consider investing in flannel sheets and a warm comforter for your bed and keeping your apartment cooler when you sleep.
Keep your furnace clean and unblocked. Keeping your furnace and vents properly maintained will reduce energy consumption and help you save. Check your furnace filter monthly, and replace it when it gets dirty.
Use a space heater only in the current room you are hanging out in. This will take the nip out of the air to make you feel more comfortable without heating all of the other rooms in the house and wasting energy.
Use silicone to fill any cracks in doors, windows, etc, including the basement floor and walls. You would be surprised at how much heat is lost through cracks that seem insignificant. A tube of caulk or silicone will only run you a few dollars and it’s an easy weekend project.
