a cold storage compartment within the cooling space arranged at an interior of the ice-lined cold storage device;
an ice-lining configured to absorb heat from the interior of the cold-storage device;
a cooling circuit configured, when in operation, to remove heat from the ice-lining;
an inner liner arranged between the cold storage compartment and the ice-lining, in which the inner liner circumscribes the cold storage compartment and defines a substantially continuous perimeter of the cold storage compartment, and in which the inner liner comprises
a heat conducting metal sheet having a first major surface which faces towards the cold storage compartment and a second major surface which faces towards the ice-lining; and
a thermally insulating material which separates the cold storage compartment from the ice-lining and which is arranged between the heat conducting sheet and the ice-lining; and in which
an electrical heating element is arranged between the heat conducting sheet of the inner liner and the thermal insulating material of the inner liner,
