ABSTRACT OF THE DISCLOSURE A small, compact heating device for warming small quantities of edible liquid ready for consumption comprises a heat tube having an outer heat insulating layer covering its central, intermediate zone, and a heat source for heating the evaporator end zone. The device is used for heating liquid in a cup or similar container, by immersing the condenser end of the heat pipe in the bottom of the liquid in the cup, with the insulated portion contacting the liquid surface. The heating means is applied to heat the evaporator end of the heat pipe, and the heat is transferred by the heat pipe to the bottom of the liquid for efficient heating of the liquid ready for consumption. The evaporator end may be surrounded by a chimney, for more efficient heating thereof, and to conduct combustion fumes away from the edible liquid. The fuel may be solid hydrocarbon fuel, and placed on the bottom wall of the chimney for combustion. Alternatively it may be a liquid or gaseous fuel, with the heating means being, for example, a cigarette lighter releasably clamped to the heat pipe in the vicinity of the end of the chimney. The apparatus is particularly useful for hikers, skiers, campers and troupes on outdoor military exercises, who require hot nourishment but cannot conveniently carry bulky heating apparatus.
