One of the best
things you can do to use less energy, reduce the amount of
pollution you are personally responsible for and reduce your
heating bill is to replace your old furnace with a newer, fuel
efficient one.
|
An
older furnace may be only 66% efficient and cost up to
$730 per year to operate.
Over 10
years, an Energy Star furnace could save as much as $1,700
in energy costs. |
AFUE (Annual
Fuel Utilization Efficiency) is the standard measure of fuel
efficiency for furnaces. The higher the AFUE percentage, the
more energy-efficient or fuel-efficient the furnace. The U.S.
government’s established minimum AFUE rating for a furnace is
78 percent. ENERGY STAR qualified furnaces have an AFUE rating of 90% or greater, making
them about 15% more efficient than standard models. The most
efficient models have AFUE ratings over 94%.
|
Heating
can account for almost 2/3 of your annual energy bill. |
Manufacturers of
furnaces that have earned the ENERGY STAR label include some
of the recognized names like Amana, Carrier, Bryant,
Rheem-Ruud, and Trane. Look for the ENERGY STAR logo when
looking for a new furnace.
When looking for
a furnace, you may want to look for one with a variable speed
fan. These can be quieter than conventional units.
