An apparatus for heating or cooling a material to be heated or to be cooled, the apparatus comprising:
- a first compartment for containing the material to be heated or to be cooled;
- a second compartment containing a phase change material, wherein the phase change material is either for generating heat to heat the first compartment or absorbing heat to cool the first compartment when undergoing a phase change;
- and
- an activating arrangement comprising a phase change activating agent and a barrier that separates the phase change activating agent from the phase change material, wherein the activating arrangement is configured to cause the barrier to rupture when operated so that the phase change activating agent contacts the phase change material in order to activate a change of phase of the phase change material, and wherein the barrier is configured to re-seal after being ruptured.
