The Big Buddy is a portable propane heater that delivers radiant warmth to spaces up to 450 square feet. This liquid propane heater connects directly to 1 lb. propane cylinders and is one of the most popular portable propane heaters available. It provides a heating solution for supplemental warmth wherever you need it.
The Big Buddy is designed for convenient portability and ease of use. Its built-in carry handle makes it simple to move between locations, while dual swivel regulators allow you to adapt from disposable cylinders to a remote gas supply with the purchase of an optional hose and filter. Safety features including an Oxygen Depletion Sensor (ODS) and accidental tip-over shut-off provide protection during operation.
