## How Dishwashers Heat Water
Dishwashers are a common household appliance that can save you a lot of time and effort when it comes to cleaning dishes. But how do dishwashers heat water?
There are two main ways that dishwashers heat water:
1. Electric heating element: This is the most common type of heating element used in dishwashers. It works by passing an electric current through a metal coil, which heats up the water.
2. Gas burner: A gas burner is a less common type of heating element used in dishwashers. It works by burning gas to heat the water.
## Electric Heating Element
The electric heating element is located at the bottom of the dishwasher tub. It is typically made of stainless steel or copper. When the dishwasher is turned on, the heating element is energized and begins to heat the water.
The temperature of the water is controlled by a thermostat. The thermostat is located near the heating element and it senses the temperature of the water. When the water reaches the desired temperature, the thermostat turns off the heating element.
## Gas Burner
The gas burner is located at the bottom of the dishwasher tub. It is typically made of stainless steel or cast iron. When the dishwasher is turned on, the gas burner is ignited and it begins to burn gas.
The gas burner heats the water by conduction. This means that the heat from the burner is transferred to the water through direct contact.
The temperature of the water is controlled by a thermostat. The thermostat is located near the gas burner and it senses the temperature of the water. When the water reaches the desired temperature, the thermostat turns off the gas burner.
## Which Type of Heating Element Is Better?
The type of heating element that is best for you will depend on your specific needs. Electric heating elements are more common and they are typically less expensive than gas burners. However, gas burners can heat water more quickly than electric heating elements.
## How to Choose a Dishwasher
When choosing a dishwasher, you should consider the following factors:
The size of your household: If you have a large household, you will need a dishwasher with a large capacity.
The type of dishes you wash: If you wash a lot of pots and pans, you will need a dishwasher with a powerful heating element.
Your budget: Dishwashers can range in price from a few hundred dollars to over a thousand dollars. Set a budget before you start shopping so that you can narrow down your choices.
## Dishwasher Water Temperature
The water temperature in a dishwasher is typically set to between 120 and 140 degrees Fahrenheit. This temperature is high enough to kill bacteria and remove food residue from dishes.
Some dishwashers have a “sanitize” cycle that heats the water to a higher temperature, typically 165 degrees Fahrenheit. This cycle is recommended for dishes that are heavily soiled or that have been used to store food.
## Energy Efficiency
Dishwashers can be a major source of energy consumption in your home. To save energy, choose a dishwasher with an Energy Star rating. Energy Star dishwashers are designed to be more energy efficient than standard dishwashers.
## Conclusion
Dishwashers are a convenient and efficient way to clean dishes. By understanding how dishwashers heat water, you can choose the best dishwasher for your needs.
