Electric water boiler

An electric water boiler, also called a thermo pot or tea urn in British English, is a consumer electronics small appliance used for boiling water and maintaining it at a constant temperature in an enclosed reservoir. It is typically used to provide an immediate source of hot water for making tea, hot chocolate, coffee, instant noodles, or baby formula, or for any other household use where clean hot water is required. They are a common component of Japanese kitchens and the kitchens of many East Asian countries but are found in varying use globally. Smaller units are portable. Some thermo pots are designed with a feature that can purify water.
