ABSTRACT:
A collapsible heating device for building a fire using solid fuel is disclosed wherein the heating device includes a canister defining a hollow cavity, the canister having an open end. A base corresponding to the canister is configured to mate with the open end so as to detachably close the open end. A perforated lower burner defining a hollow core is supported on the base. A perforated upper burner defining a hollow core is removably nestable within the lower burner. The upper burner is movable between a first collapsed position, wherein the upper burner is disposed within the lower burner, and a second operative position, wherein the upper burner is supported upright on the lower burner. When the upper burner is in the first collapsed position, the canister may mate with the base to extinguish the fire.
