Abstract
A heater product may have a first cavity in which a first part of a heater composition is disposed, a second cavity in which a second part of a heater composition is disposed, and a barrier between the first cavity and the second cavity, such that when the barrier is removed, the first and second parts combine to provide an exothermic reaction. A pull strip may be used to remove the barrier, and at least one reinforcing strip may be used to guide the pull strip. The first part may include calcium oxide and the second part may include water, an reaction-initiation delayer and water-release limiter.
