The prevailing idea that is prevalent in the society is that washing dishes by hand is friendlier to the environment, but little do you know that built-in dishwashers actually beat hand-washing dishes, in a runaway. A study conducted at University of Bonn in Germany shows that dishwasher machines use only half the energy (one sixth of the water), less soap, to boot. Sounds simple isn’t it? Well, the fact of the matter is not merely black-and-white. How much water does a dishwasher use exactly and how is it better for the environment?
As stated before, a study at University of Bonn shows that the average amount of water one uses to wash dishes by hand is 10 and a half litres every day. Well, it may not seem a lot at first glance but it only takes into account cooking of meals. However, when talking about an entire household with two or three people in it, the figure would be ranging from a shy 21 up to 31.5 litres a day. So, that’s the answer to your ‘How much water does a dishwasher use?’ conundrum.
Now wait a moment. That has yet to cover it all and it still does not sound like a lot of water. Now compare it to the average modern dishwasher running on a full cycle, which takes 15 litres, it’s not that great. That’s stacked to capacity by a whole household, not just every meal. That being said, if you are like any other households which only need to run their dishwasher once a day, you might want to stop your habit of washing dishes by hands, stat.
Buying a new dishwasher should be considered as picking a new investment. Typically, homeowners keep their dishwasher machines for as long as seven years. That’s why, it’s worth considering whether popular brands are willing to cut costs to both the environment and you. Should it prove to be effective, this could very well sway the mind of practically any hand washing hardcore fans.
Considering the fact that dishwasher machines always seem to spray water, is it possible to use less water? The answer is yes. Modern dishwashers that have eco-friendly labels have the ability to use as little water per cycle as 6 litres. Such thing is usually part of the manufacturer’s plan to reduce the amount of water consumption by the dishwasher by as much as 80 to 85%.
Getting your dishes clean by hand can use up to 27 gallons of water/load. As stated by the Natural Resources Defence Council, a dishwasher that’s Energy Star certified is proven effective to use as little as three gallons/load, which amounts to 11 litres. As a matter of fact, this kind of dishwasher (Energy Star certified) can pretty much save over 5,000 gallons of water annually.
Moreover, brands like Bosch even relies on technology called ActiveWater which promises to optimise dish cleaning efficiency through uses of targeted water filters, distribution, increased water circulation and faster heating.
Bottom line, you should never be clouded with doubt about dumping your dirty dishes into the dishwasher machine as long as you are using it appropriately. It’s been proven to be much more cost and water efficient so what’s the harm, right? The trick is never to run the dishwasher when it is only half full of dirty dishes
So, if your friends throw the ‘How much water does a dishwasher use?’ question at your face, give them this receipt!
