Firebox for water for camping

Abstract

A portable heating device includes an enclosed structure for containing and heating water. The firebox is constructed of steel and sits on four removable legs, allowing a campfire to burn on top of and underneath the firebox, maximizing heating elements. The heating of large quantities of water can be achieved by circulating water from a reservoir, through heat resistant hoses to the firebox, and then back into the reservoir once heated. This feature allows a hot tub for camping. A receptacle is placed in the upper firebox allowing a support post to be inserted, which supports a swivel arm or swivel grill for meal preparation. With the attachment of a steam diffuser, the portable heater can be used in combination with a sealable tent to become a sweat lodge. The device is also self-contained and easily transported by its conversion into a carrying case when not in use.
