Though based closely on the classic form of traditional electric kettles, this new design contains a key conceptual innovation. Thanks to vacuum technology, this kettle not only heats water, but keeps it hot after the electric current is turned off. This greatly reduces the amount of energy needed to reheat water. Its clear geometric form and minimalist styling make this an attractive appliance. The internal structure facilitates cleaning and the material is environmentally friendly and safe to use. Close attention to ergonomics mean that it is easy and convenient to use.
