Abstract
The present invention relates to a method for manufacturing a heating device which is capable of generating heat when exposed to oxygen. The heat generating element comprises activated carbon and iron is used to generate an exothermic oxidation reaction within the heating device. Introducing an oxidation inhibitor during the manufacturing process allows the manufacturing of the device to take place in ambient atmospheric conditions. The present invention also includes a loading facilitator which allows the heat generating medium to be more easily and efficiently loaded into the heat generating device. When appropriate, the oxidation inhibitor and loading facilitator can be removed.
