When it comes to appliances, we normally look at how energy efficient they are; this is the case even with dishwashers. But have you ever wondered just how water efficient are dishwashers in our homes?
After all, aside from the energy used, dishwashers rely on substantial amounts of water to get the job of cleaning our dishes and utensils done properly. There are even some debates that washing by hand is more water efficient than using dishwashers. Do you think this is the case?
One of the greatest determinants for water efficiency of dishwashers is making wise choices. All appliances in the United States come with Energy Star ratings. This means that they are designed to consume about 25% less energy than the minimum standard mandated by law. You may say that that is all well and good in terms of energy consumption, but what about water consumption?
It is a fact that by choosing Energy Start rated dishwashers, 175 billion gallons of water can be saved until 2025. This amount of water is sufficient to meet the demands of 3 million people. This means that Energy Star rated dishwashers can indeed deliver substantial savings in water usage and are designed for water efficiency.
Full Load Efficiency
Dishwasher manufacturers and distributors recommend waiting for the dishwasher to have a full load before running it. This rule sounds similar to that of the clothes washer and with good cause since the noticeable difference between the two is one cleans dishes while the other cleans clothes.
Anyway, running the dishwasher with a full load helps to maximize energy and detergent usage as well as makes it more efficient in using water.
Efficient loading of the dishwasher, which means fully loading it without overloading, can also result in increased water efficiency. Water efficient loading of dishwashers can create savings of around 1,000 gallons of water every month.
Right Size and Model
Related to the Energy Star rating described earlier, choosing the right size and model of dishwasher can help you achieve water efficiency. Obviously, if you are leaving on your own, choosing a compact model would be more water efficient than buying a larger one that relies on more water usage.
Most top-rated dishwasher models in the market today make use of approximately four gallons of water per washing, compared to about six or more gallons for older models. In fact, you can save about $40 a year in energy costs and roughly about 1,000 gallons of water if you replace your 1994 or older dishwasher models with newer ones.
The WELS Label
If you live in Australia, you may want to check the WELS label for all water-using appliances to find out its water efficiency rating. Similar to the Energy Star rating, the more stars you see on the label, the more efficient the product is when it comes to water consumption.
The WELS dishwashers can use only half of the amount of water that average dishwasher models use. This means that approximately 300 million gallons of water can be saved annually from its usage. This is enough to completely fill 600 Olympic-sized swimming pools.
As for the contention that washing by hand is more water efficient, it will never beat out the savings on dishwashing a full load of dishes.
Let us say that there are about 130 items to be washed using about 2 gallons of water, which is the average consumption for the most water-efficient model in the market; this means you need to wash all items by hand with less than a bowl of water, without running the tap, and forgetting about rinsing.
So, hands down, dishwashers are more water efficient than washing by hand. Go and visit Faulkner’s Appliance Center today to get the best deal on water efficient and reasonably priced dishwasher models that are right for your needs.
