An important thing to consider when choosing a dishwasher is that up to 60% of all the energy is used to heat the water. For this reason the more water efficient the machine the less energy it uses.
Fortunately due to national standards all new machines now use a fraction of the energy that was previously used by older models.
The national limits are 6.5 gallons per each cycle; and the very best models use as little as 1.5 gallons per cycle. The water use has not reduced the quality of a wash either.
Tips For Using Dishwashers
How To Choose A Dishwasher
If you are looking to buy a dishwasher and don’t know where to start this guide will help you make the best choice for your needs when choosing.
Here are some things to consider:
1. Look At The Energy Use
The estimated energy use recommended by the ACEEE is less than 295 kWh/year. Which is a better number than the federal standard by a whooping 40%.
To find the energy use of a machine it should be indicated on the energy guide label which is on the front of the machine in most cases.
2. Look For Low Water Use
The most efficient dishwasher models are more than just an energy star rating or energy guide.
The energy star may not take into consideration the amount of water a machine uses in many cases. So you can find machines that use as much as half the water or other machines. This means a saving of hundreds of gallons of water each year.
You can check the manufacturers instructions and contact your local water utility. It is also possible to get some good rebates if you purchase a machine that meets the right energy efficient requirements.
3. Check For The Amount Of Wash Cycle Options
You will find that with most dishwashers they have a different selection of wash cycles. The more option for cycles you have the better you can work out how to save energy and water needed for each load.
The manufacturers instruction will be able to give you the total water use with all the different cycles.
It is also possible to get a dishwasher fitted with a “soil sensor”. These machines will adjust water use depending on how dirty dishes are for each load. Remember you can still find efficient dishwashers without this feature too.
4. Save Energy With A “No-Heat” Dry Machine
A lot of machines will use an electric heating element to dry dishes once the final rinse is complete. This will usually use about 7% of the dishwashers energy.
There are now plenty of machines that offer an energy saving no heat feature. When this feature is selected, the room air is circulated through the dishwasher with the use of a fan, instead of electricity.
*These tips above are some of the top dishwasher tips to consider when choosing a machine*.
Here are some energy saving tips that you can use also – for a new or existing dishwasher you own.
Energy Saving Tips
The way you operate your dishwasher can have a major impact on how much energy you can save when using it.
Stay Away From Hand-Washing
There have been reports that show modern dishwashers as the most cost effective and energy saving device around. They even out perform hand washing.
Consider Your Rinsing Method
It has been shown that many people are likely to pre-rinse their dishes before they are loaded into a dishwasher. This is done even though modern day machines do this superbly. When rinsing dishes its best to use cold water.
Use The Manufacturer Instructions
You should always completely fill all the racks in a machine so that the water and energy used is properly maximized, and this also allows for adequate circulation
You Should Wash Only Full Loads
You should keep in mind that a dishwasher will use the same amount of water no matter whether it’s half full or full.
For this reason it is best to wash dishes when the machine is full. If it takes a while to fill the machine you can use the rinse and hold feature. This is found on a lot of dishwashers to prevent food from drying on dishes.
This feature is better than pre-rinsing dishes individually and typically uses only 1 to 2 gallons of water.
Choose Energy-Saving Cycle Options
You should be aware of all the cycle options that you have available to you. You should then choose the best and most energy efficient option for the job in hand.
You can also use the no heat air dry option if this is available on your dishwasher.
Decrease The Water Heater Temperature
A lot of dishwashers in the U.S. have a built in heater which is for boosting water temperature to the temperature recommended by manufacturers of 140 –145°F. Which should produce optimum dish-washing performance.
The great advantage of this heater is that it can be turned down to half way between low and medium heat i.e 120F.
So now you have dishwasher maintenance tips as well as a place to start when choosing a dishwasher that you can use to find the very best machine for your needs.
