ABSTRACT:
Apparatus for heating water over an open fire comprises a kettle having a substantially flat bottom and an upstanding perimeter sidewall. Two openings are provided in the upper portion of the sidewall of the kettle. A water inlet tube extends through one of the openings and has an open, inner end that is positioned in the lower portion of the interior of the kettle. The open, outer end of the water inlet tube is positioned outside the kettle and is adapted to have aliquots of cold water poured into the open end so that the cold water will flow into the kettle through the water inlet tube, with the cold water entering the lower portion of the interior of the kettle. A water outlet tube extends through the other opening and has an open, inner end that is positioned in the upper portion of the interior of the kettle. The open, outer end of the water outlet tube is positioned outside the kettle and forms a hot water spout on the outside of the kettle. As aliquots of cold water are poured into the water inlet tube, similar sized aliquots of hot water are dispensed from the kettle through the water outlet tube. The kettle remains full of water at all times, and the cold water is rapidly heated in the bottom portion of the kettle. The heated water rises to the upper portion of the kettle as additional cold water is added to the kettle.
