How It Works
Electric clothes dryers use
electrical heating elements to dry clothes as they tumble around in a rotating
drum. An electric motor and drive belt keep the drum in motion while a flexible
duct carries away any remaining moisture. Heating temperature and cycle times
can be adjusted with controls on the top or front of the dryer.
What Can Go Wrong?
Beware of overheating when it comes to your electric dryer. The unit must be able to exhaust its
heated air to avoid damaging its internal components. A backup in the exhaust
vent can be caused by a buildup of lint, faulty installation or confined space.
Environmental Impact
The power consumption of most electric
dryers depends on the heat setting for each load. The average range is
between 1800 watts (W) and 5000 W. Operating at 3,000 W for 6 hours each week,
a typical dryer would consume 936 kilowatt-hours (kWh) and produce about 1,440
pounds of carbon dioxide (CO2).
Gas versus Electric Dryer
Electric clothes dryers are
easy to install and generally less expensive than gas dryers. However, electric dryers use much more electricity than gas dryers, so they can be less cost effective over time.
