Energy Consumption FAQ For Dishwashers
Ahead, I answer the most-asked questions about average energy consumption by regular dishwashers. Find more about energy and water use in these devices.
- How Much Water Does A Dishwasher Consume?
The modern standard (regular sized) Energy Star dishwashers utilize up to 3 gallons of water per cycle. This is an average calculation. Brands design these dishwashing devices in such a way to utilize and heat only a limited quantity of water, which is then recycled.
- What Is The Electricity Consumption Of A Dishwasher?
In general, dishwashers consume up to 1400 watts of energy. Another way to look at it is that one cycle can consume up to 1-2 units of energy. Also, depending on the size of your team, the device can consume from 600 to 2400 watts per cycle.
- How To Measure Energy Efficiency In Dishwashers?
Of course, the quickest way to know the energy efficiency of any dishwasher is to check its Energy Star ratings. Generally, dishwashers with Energy Star ratings can save 5% to as much as 50% more water than the non-rated models. Use these Energy Star ratings to compare and contrast the energy efficiency of different models.
What To Look For While Buying New Energy Efficient Dishwashers?
If you want a more energy-efficient dishwasher, I suggest that you must consider the following features while buying a new dishwasher (apart from Energy Star ratings):
- No-Heat Drying Function
Most modern dishwashers must feature no heat drying in the final step, where it circulates the air around the room to dry the dishes. This can save up to 7% of total energy consumption by a dishwasher.
- Eco-Cycle Options
Many dishwashers also come with Eco Wash cycle options. This wash setting typically uses less water to clean lightly soiled or half-full dishwashers.
- Smart Sensor Washing
Some dishwashers use “Auto wash” programs (soil sensors) to determine how full and dirty the load is. These devices will then change the water and temperature according to what it detects.
- Dishwasher Size
Generally, the smaller the dishwasher is, the less water and power it will consume. So, if your needs can be fulfilled with a compact dishwasher, definitely consider buying that.
