Mr. Heater Big Buddy Portable Propane Heater

The Most Popular Portable Propane Heater in North America. The Mr. Heater Big Buddy Portable Propane Heater is a patented radiant 4,000-18,000 BTU Liquid Propane heater connects directly to two 1 lb. cylinders. Additionally, this heater is the perfect solution for heating enclosed spaces like cabins up to 450 sq. ft. 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 as well as a single filter.
