Kelly Kettle, Storm Kettle, Thermette and Volcano Kettle are trade names for efficient portable devices for boiling water outdoors using twigs and other small combustible materials; these devices consist of a water jacket surrounding a fire chamber which creates an upward chimney draft ensuring efficient and rapid boiling even in windy or wet weather. Kelly Kettle and Volcano Kettle are registered trademarks of the Kelly Kettle company〔(【引用サイトリンク】title=Case details for Community Trade Mark E5001078 )〕〔(【引用サイトリンク】title=Case details for Trade Mark 2148045 )〕〔(【引用サイトリンク】title=Case details for Community Trade Mark E5576285 )〕 which first produced the product in Ireland in the early 1900s. The Thermette was first manufactured in New Zealand in 1929 and was standard issue for the New Zealand Army during World War II where it was known as a Benghazi boiler. Other companies, including the Eydon Kettle Company started manufacture at later dates. Earlier examples of water heaters using a water jacket include heavier samovar tea urns from Eastern, Central, and Southeastern Europe, as well as the Middle East. ==History== Early examples (estimated at about 3,600 years) of devices that heat water surrounding a fire include samovar tea urns from Eastern, Central, and Southeastern Europe, as well as the Middle East.
