Electric Water Heater

An electric water heater is an appliance that is used to heat water. It is more correctly known as an electric water boiler. However, the heater can be used to just heat water to a required temperature and not actually bring it to a boiling point. Most people use these heaters to actually boil water for health and hygiene reasons. Water that is boiled will not contain any microorganisms and hence will be perfectly proper to use. At the same time, the electric water heater can be used to warm water for making various beverages and drinks and for cooking purposes.

The principle of an electric water heater is quite straightforward. The water heater is essentially a vessel at the base of which a heating apparatus is present. This apparatus contains a heating coil inside it along with a thermostat and a sensor that attaches to the underside of the base of the electric water heater. When the water is to be heated, the switch is turned on. Due to the flow of the electric current, the heating coil becomes hot and the water present in the vessel starts getting heated up.

The thermostat is placed to adjust the temperature of the water that is heating. Control knobs for adjusting various temperature levels are provided on the main body of the electric water heater. The user will set a particular temperature and this will be recorded by the thermostat. As the water is heating, the sensor will detect what temperature the water is at. If the temperature reaches the level set by the user, the thermostat will shut down the heating coil and the temperature will then remain at the level set by the user. If the temperature starts falling down, the thermostat will detect that the water has cooled below desirable value and will set the heater coil in operation once again. In this manner, the thermostat helps keep the temperature at the required level.

The manner in which the water is dispensed from the electric water heater after it has reached the required temperature is the point that creates the greatest variety in them. Most of these electric water heaters have a simple dispensing system through a spout, just like a teakettle. These will also be shaped like a teakettle, with an insulated handle to make for easy pouring out of the water that has been heated. Some of them have a diaphragm pump system. These water heaters will dispense water when a particular button is pressed. The receptacle for containing the water as it flows out is meant to be placed beneath a faucet-like arrangement. These units act as standalone units and are often used in commercial places.

Electric water heaters are undeniably a very important household resource. Simple varieties of these appliances are found in almost all households. The ones that are found are usually the inexpensive teakettle-resembling ones. These are used for all beverage requirements and in some cases, even for preparing the beverages directly, such as tea and coffee.

New developments in the electric water heater include the tankless varieties. There is a strong disagreement about using tanks in water heaters because it leads to waste of electricity. The tankless water heaters are attached to the main plumbing line of the home itself and so it can be used to retrieve water as and when required. This allows only the requisite amount of water to be heated at a time and prevents wastage.

There are also appliances today that can provide both hot and cold water through a single arrangement. These are the most convenient ones to use because it eliminates the need of a water cooler in the summer months.
