Lower your thermostat by 1 degree. During the winter months, as much as 3% of the energy your furnace uses can be saved.
Install a programmable thermostat. It will automatically turn the heat up before you wake, turn the heat down when you leave home and back up when you return. If you use it to set back the temperature by 10 degrees for eight hours every night, you'll lower your heating bills by 10%. A $50 digital thermostat can pay for itself in energy savings in less than a year.
Recommended thermostat settings for a comfortable environment are 21 degrees C when you are home relaxing, 18 degrees C when you are sleeping, and 15 degrees C when you are away from your home for an extended period of time.
Ensure that the hole in the wall behind the thermostat is insulated. This will prevent any drafts. Also, install your thermostat out of direct sunlight and away from cold air or drafts.
Every few months, remove the thermostat cover and dust it gently with a soft brush.
If your furnace is more than 18 or 20 years old, it may be more cost-effective in the long run to replace it with a newer unit offering greater efficiency and lower operating costs.
During the winter, remove window air conditioners and seal the windows with caulk and weather-stripping.
Change or clean your furnace filter once a month. Dust and dirt can quickly clog vital parts, making your furnace run harder and eventually break down.
Have your heating system inspected regularly - especially if it's natural gas. A $50-$100 annual tune-up can help reduce your heating costs by up to 5%.
If you have a forced-air furnace, do NOT close off heat registers in unused rooms. Your furnace is designed to heat a specific square footage of space and can't sense a register is closed - it will continue working at the same pace. In addition, the cold air from unheated rooms can escape into the rest of the house, reducing the effectiveness of all your insulating and weatherizing.
Don't set the thermostat higher than required. It won't heat your home any faster, and it will keep your furnace running longer than necessary.
Vacuum registers and vents regularly, and don't let furniture and draperies block the air flow. Inexpensive plastic deflectors can direct air under tables and chairs.
If your home has a boiler system, avoid covering radiators with screens or blocking them with furniture. It's also a good idea to add a reflecting panel behind radiators - you can purchase one at a home center or make one yourself with a plywood panel and aluminum foil.
If your home has electric baseboard heating, be sure to keep furniture and draperies away from the heaters, and leave at least a three-inch clearance under the heating unit.
Keep curtains and blinds closed at night to keep cold air out, but open them during the day to let the sun warm the room.
Avoid using space heaters, including electric, kerosene or propane models. Not only are they expensive to operate, they're also very dangerous.
Add area rugs to rooms with hardwood or tile floors to keep your feet warm.
Lower the thermostat to 55 degrees when on vacation. This will save energy while preventing water pipes from freezing.
