Boilers
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. Electric water boilers have a built in thermostat that detects when water has reached its boiling point of 100 °C (212 °F) to automatically shut off. (source Wikipedia)
