Abstract
A system and method for controlling the surface temperature of a heat pack, wherein the heating bag comprises an exothermic chemical reaction as the heat source, a phase changing material as a buffer, and a means of controlling the rate of reaction. Optionally, the system may include one or more thermally conducting materials to increase the rate of heat transfer from the heat pack to the user.
