For Sale: Propane Patio Heater. Approx. 6 years old. Hardly used, maybe five to eight times. It has been sitting outside its entire life so it has some surface rust on the body cabinet but it blends in well with the antique brass colored original finish. We tend to use our propane fire place instead of this unit. We bought it new at Keller Hearth and Home in Mandan, and recall that we spent mid to upper $400.00s for it. 70 high. 36,000 BTU. Propane tank pictured not included. Smoke Free and Pet Free Home. Thank you. $200.00 OBO.
