An electric water boiler, also sometimes called an electric dispensing pot, electric water heater, electric water urn, or electric kettle, is a consumer electronics small appliance used for boiling water and possibly maintaining it at a constant temperature. It is typically used to provide an immediate source of hot water for making tea, hot chocolate, ramen noodles, or baby formula, or any other household use where clean hot water is required.

An electric water boiler consists of a water reservoir with a heating element at the bottom. Some models offer multiple temperature settings. Other models are part of larger water systems that boil water and provide hot, cold, and lukewarm water. Water may be dispensed in various ways, e.g. by pouring, an electric pump or by pressing a large button that functions as a diaphragm pump. Some electric water boilers have a built in thermometer that detects when water has reached its boiling point of 100 °C (212 °F) to automatically shut off.

Water Boilers Requirements
Water treatment is required to provide the physical plant with properly treated water in sufficient quantities to meet plant needs. All system require water treatment by using speciality chemicals such as corrosion and scale inhibitors , however open systems require constant water treatment to deal with the constant need for treated water to make-up for system losses of often up to 100%. Closed systems also require water treatment, but due to minimal system losses, that treatment commonly occurs only at the system fill source.
Industrial water treatment for cooling water systems , water treatment boiler requires advanced water technologies ,keeping in mind chemistry of water and use of advanced formulations of corrosion and scale inhibitors .
Three tools can be used to improve water quality:
* Internal Treatment – conditioning the boiler water to pre-determined levels by using a variety of chemicals.
* Demineralization/ Reverse Osmosis / Electrodialysis - the replacement of specific inorganic salts by ion exchange.
* Deaeration – the removal of dissolved oxygen and carbon dioxide by heating and atomizing the water with steam.
While demineralization and deaeration can be accomplished easily by investment in the appropriate support equipment, internal treatment calls for a more concerted effort. However, most organizations large enough to have in-house maintenance will find that the combination of these three tools will more than pay for themselves in defrayed operating costs. A well-implemented program will ensure -
* Increased heat transfer
* Lower fuel expenditures
* Lower chemical consumption
