Like new - without original packaging. Includes manual. This portable B.O.S.S. water heater with shower attachment is a life saver when away from conventional heated water utilities. The XB13 can be used as recommended with a 1-pound LP bottle; or connected like other Mr. Heater products to a larger bottle through aftermarket hoses and accessories. Don't be caught without hot water when no one else is around. Make your own with this Mr. Heater XB13 Battery Operated Shower System (B.O.S.S.). This unit operates on 6 x D - cell Batteries: 4 as pictured above to operate the pump & 2 inside the base unit for the piezo automatic igniter. No pilot light means no wasted fuel. Burner actives while water is moving through the base unit. Then turns off when water flow stops.
