An electric water boiler, also sometimes called an electric dispensing pot, electric water heater, or electric water urn, is a consumer electronics small appliance used for boiling water and 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.
Electric water boilers are popular throughout East Asia but may be found in any country where tea drinking is enjoyed.
An electric water boiler consists of an insulated vacuum flask of several liters with an unexposed heating element in the bottom. It typically boils water when initially added and then maintains it at a set temperature slightly below the boiling point. 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 is dispensed in some models by an electric pump and others by pressing a large button that functions as a diaphragm pump.
