1. A heating device comprising:
a flexible housing that defines a plurality of heater segments,
wherein each heater segment comprises:
a first compartment containing a first reactant;
a second compartment containing a second reactant; and
a frangible seal between the first compartment and the second compartment,
wherein the first reactant and the second reactant are configured to react exothermically upon contact with one another,
wherein the flexible housing is formed from a flat flexible sheet and a contoured flexible sheet coupled to one another, the contoured flexible sheet is contoured to define a plurality of first pockets and a plurality of second pockets, wherein the plurality of first pockets and the plurality of second pockets are configured such that: A) each first compartment is defined by one of the plurality of first pockets in the contoured flexible sheet and the flat flexible sheet, and B) each second compartment is defined by one of the plurality of second pockets in the contoured flexible sheet and the flat flexible sheet,
wherein the flat flexible sheet is sealed against the contoured flexible sheet to form the frangible seal between the first compartment and the second compartment in each of the heater segments, and wherein the flat flexible sheet is sealed against the contoured flexible sheet to form additional, non-frangible seals that remain intact when the frangible seals rupture, the additional non-frangible seals extend around each of the first and second compartments except where the frangible seals are located, and
fasteners that can mate with one another at opposite ends of the heating device.
