The present invention provides a kettle that has a plurality of chambers and which is configured to boil water in one chamber and condense the steam therefrom in another chamber or other part of the kettle. The kettle may have a heating element in one of the chambers that raises the temperature of the water in that chamber to boiling point and the heating of the water is carried out in stages, each stage elevating the temperature farther and being carried out in a successive one of the chambers. The kettle allows water to be boiled far more efficiently than in conventional kettles and can have a significant impact not only in reducing house¬ hold carbon footprint but also in reducing demand spikes in electricity usage, |
