Household Heating
Systems
Although
several different types of fuels are available to heat our homes, more
than half of us use natural gas.
Heating
and cooling your home uses more energy and drains more energy dollars
than any other system in your home. Typically, 45% of your utility bill
goes for heating and cooling. What's more, heating and cooling systems
in the United States together emit 150 million tons of carbon dioxide
into the atmosphere each year, adding to global climate change. They
also generate about 12% of the nation's sulfur dioxide and 4% of the
nitrogen oxides, the chief ingredients in acid rain.
No matter
what kind of heating, ventilation, and air-conditioning system you have
in your house, you can save money and increase your comfort by properly
maintaining and upgrading your equipment. But remember, an
energy-efficient furnace alone will not have as great an impact on your
energy bills as using the whole-house approach. By combining proper
equipment maintenance and upgrades with appropriate insulation, air
sealing, and thermostat settings, you can cut your energy use for
heating and cooling, and reduce environmental emissions, from 20% to
50%.
Follow
these
tips to save on energy costs:
- Set the furnace
thermostat at 68 degrees or lower, and the air-conditioner thermostat
at 78 degrees or higher, health permitting. 3 percent to 5 percent more
energy is used for each degree the furnace is set above 68 degrees and
for each degree the air conditioner is set below 78 degrees.
- If your old air
conditioner is on its way out replace it with ENERGY STAR® labeled
energy-efficient model.
- Clean or replace furnace
and air-conditioner filters regularly, following manufacturer's
instructions.
- Close the damper
when the fireplace is not being used. Try not to use the fireplace and
central heating system at the same time.
- Set your thermostat as
low as is comfortable in the winter and as high as is comfortable in
the summer.
- Clean or replace filters
on furnaces once a month or as needed.
- Clean warm-air
registers, baseboard heaters, and radiators as needed; make sure
they're not blocked by furniture, carpeting, or drapes.
- Place heat-resistant
radiator reflectors between exterior walls and the radiators.
- Turn off kitchen, bath,
and other exhaust fans within 20 minutes after you are done cooking or
bathing; when replacing exhaust fans, consider installing
high-efficiency, low-noise models.
- During the heating
season, keep the draperies and shades on your southfacing windows open
during the day to allow the sunlight to enter your home and closed at
night to reduce the chill you may feel from cold windows.
- During the cooling
season, keep the window coverings closed during the day to prevent
solar gain.
