In the case of washers, according to the Federal Trade Commission's appliances guide, upgrading washers every 10 years or so can save you more.
The EnergyGuide label can be a useful tool when comparing appliances. Here are a few facts about energy-efficient washers and dryers to consider before making your next purchase:
The truth about energy-efficient dryers.
ENERGY STAR doesn't rate dryers because their efficiency has been about the same for years, according to LifeHacker.com. The average cost of a new dryer is $550.
Regular dryer maintenance will keep your dryer from breaking and heat clothes a little quicker which can save you money. In addition to cleaning the lint trap every load, vacuum the area below the lint trap periodically to decrease the dry time and save a few cents every month.
The truth about energy-efficient clothes washers.
New models have become more efficient by switching to the front-load clothes washer, using around 50 percent less water and 37 percent less energy. The average price of a new ENERGY STAR washing machine is $750, also according to LifeHacker.com.
Maintenance will not do much to make a washing machine more efficient.
If your washer is over 10 years old or a top-load washer, you could save up to $135 a year on both water and electricity by buying a new or newer front-load washer.
The truth about HE vs. energy-efficient.
Beware of high efficiency (HE) claims since this designation is intended to match certain washer types (for example, front load) with specially designed laundry detergent.
With no standards for energy efficiency behind the HE label, only products that have earned the ENERGY STAR are certified independently to save energy.
Last word from ENERGY STAR
Clothes washers are the second largest water user in your home. If your clothes washer was manufactured before 1999, according to the federal government, you should consider replacing it with an ENERGY STAR-certified washing machine that uses four times less energy.
ENERGY STAR-certified clothes washers use about 25 percent less energy and 45 percent less water than regular washers.
Clothes washers and dryers that have earned the ENERGY STAR use advanced features, saving $490 over the lifetime of an ENERGY STAR-certified clothes washer and more with a washer/dryer pair.
Another cool energy-saving fact: If all clothes washers and dryers sold in the U.S. were ENERGY STAR-certified, the savings would be more than $4 billion each year and prevent more than 19 billion pounds of carbon pollution annually −equal to the emissions from 1.7 million vehicles.
