The Mr. Heater Big Buddy Indoor-Safe Portable RV Propane Heater is the most Popular Portable Propane Heater in North America. This patented radiant 4,000-18,000 BTU Liquid Propane heater connects directly to two 1 lb. cylinders and is the perfect solution for heating enclosed spaces like cabins up to 450 sq. ft. An integrated fan increases the heating capacity of this unit, blending radiant and convection style heat to give you the best of both worlds.
Two swivel regulators give you the ability to adapt usage from disposable cylinders to a remote gas supply with the purchase of a single hose and filter.
To light the unit, simply push and rotate the knob. The built in Piezo sparking mechanism will take care of the rest. With the Oxygen Depletion Sensor (ODS) and accidental tip-over safety shut-off, you can be sure that you will enjoy years of comfortable outdoor safe heat.
Perfect for Emergency Heat, Tents, Campers, Workshops, Job Sites, Porches, Patios, Decks, Garages, Storage Buildings, Picnics, Tailgate Parties, Construction Trailers, Sporting Events, Barns, Sheds, Hunting Blinds, Shelters, and Ice Fishing Shanties.
