The Big Buddy is a radiant propane heater that runs on two 1 lb cylinders and puts out 4,000, 9,000 or 18,000 Btu. It is built for enclosed spaces such as cabins, garages and job sites up to about 450 sq ft. Two swivel regulators let you switch to a remote tank with a hose and filter, and a Piezo igniter, oxygen depletion sensor and tip-over shut-off are standard. It is the best-known heater in its class; rivals like the smaller Buddy and Little Buddy trade output for portability, and the Big Buddy's higher heat comes with faster fuel burn.

Owners rate the Big Buddy highly for fast, strong heat in cold cabins and garages and for its simple push-and-turn lighting. The main complaints are fuel consumption on 1 lb cylinders and the bulk of the unit.
The Big Buddy is a portable radiant propane heater with an output of 4,000 to 18,000 Btu. It connects directly to two 1 lb propane cylinders. It is designed to heat enclosed spaces such as cabins, up to 450 sq ft.
Two swivel regulators let you use disposable cylinders or a remote gas supply. Switching to a remote supply requires buying a single hose and filter. To light the heater, push in and rotate the knob. The built-in Piezo sparking mechanism does the rest.
An oxygen depletion sensor (ODS) and an accidental tip-over safety shut-off are built in for indoor use.
