Abstract: A modular heating system and method is presented that automatically dissipates thermal energy from a heater or heated package if the energy cannot be assimilated without excessive temperature increase. A heater containing reactants that generate heat when combined is placed in thermal contact with a passive thermal control material which is in thermal contact with a container configured to contain a substance to be heated. The passive thermal control material allows the transmission of heat between the heater and the container as long as the temperature of the heat passing through the passive thermal control material does not exceed the activation temperature of the material. If the temperature of the heat passing through the passive thermal control material exceeds the material's decomposition temperature, the passive thermal control material decomposes and thereby dissipates heat.
