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.
Only heat the rooms you use. If you have rooms that you never use, like guest rooms or large storage areas, close and seal off the vents in those rooms to be more energy efficient and direct the flow of air to the rooms you use most. Energy bills run, on average, $183 per month. By using a space heater in the rooms where you need it and setting the thermostat to 62 degrees, you can save approximately $200 each year.
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 lower thermostat setting. You will save up to 3 percent on your heating bill per degree lowered over a 24 hour period (or about 1 percent per 8 hours). During the winter months, you can keep your thermostat set at 68 during the day and 55 at night. Lowering the thermostat to 55 degrees while you sleep saves about 13% on your heating bill. Use a programmable thermostat to make temperature regulation easier and to save money.
Change air filters. Clean air filters permit a better flow of air through your heating system, allowing hot air to more easily flow through the vents and into your rooms. You also reduce the strain on your furnace, which can extend its life. Change your air filter monthly, or whenever it is dirty. Bonus benefit – cleaner, healthier air!
