PROBLEM TO BE SOLVED: To provide a portable heating system, having excellent heat transfer efficiency and facilitating manufacture. SOLUTION: The heating vessel includes a chamber 10 having enclosed sides, a thermally conductive bottom end and a top end forming an opening for the introduction and extraction of contents to be heated, and the bottom end has an external base. The heater includes a heat exchanger and a heat source, and the heat source has a heat outlet disposed at a fixed distance from the external bottom side and configured to deliver heat to a central area thereof. The heat exchanger includes a series of thermally conductive radially disposed fins, and the fins are coupled circumferentially about the central area of the external bottom side, the fins extending for a fixed distance to encase the heat outlet. A gas flow path is formed to allow intake of air and output of exhaust. COPYRIGHT: (C)2009,JPO&INPIT
