Energy Efficient Dishwashers
Understanding dishwasher energy efficiency
In North America, the Energy Star system is used to identify appliances whose power consumption rates are lower than federal regulations. All new energy efficient dishwashers come with Energy Star tags, but there's much more than this to look for when you're shopping for new appliances. Among the ranks of efficient dishwashers, you'll find that some models have lower annual operating costs than others. A good rule of thumb is to add the initial price of the appliance to the cost of running it for 10 years (which is the average lifespan of a dishwasher). This will give you a more comprehensive view of the expenses involved.
Beyond looking for Energy Star dishwashers, though, you should also follow smart usage guidelines to ensure you consume the least possible amount of power and put a minimal strain on your local electricity resources. To do that, you need to use dishwasher energy efficiency strategies in combination with a quality appliance.
Dishwasher Energy Efficiency Tips
Unlike energy efficient refrigerators, dishwashers are not constantly running. This gives you the opportunity to save even more on power consumption by being wise about how and when you run your new dishwasher.
First, you should only operate your dishwasher when it's full. Even the best dishwashers won't save you much money on electricity if you're running them all the time. Most families can get away with washing a full load of dishes once a day or every other day.
Another good strategy is to run your dishwasher at off-peak hours. Depending on where you live, you could be doing more than just being a good citizen. Some electricity companies charge less for power consumed during off-peak times; waiting to run your dishwasher late at night or even overnight is recommended whenever possible.
Energy Efficient Commercial Dishwashers
Remember that Energy Star ratings do not only apply to products designed for residential use. You can also get Energy Star qualified commercial dishwashers which use an average of 25 percent less power and water than models that have not earned the Energy Star rating. At current power rates, you can save an average of $800 to $1,200 per year by replacing your current commercial dishwasher with an energy efficient model.
