F274800 Big Buddy Portable Propane Heater, 4000–18000 BTU

The Mr. Heater Big Buddy is a portable propane heater designed to warm enclosed spaces up to 450 square feet. It connects directly to two 1-pound propane cylinders for convenient, portable operation, or can be adapted to a remote gas supply with an optional hose and filter for stationary installations.

This heater combines radiant and convection heating to maximize comfort and efficiency. The built-in fan circulates warm air throughout the space, blending both heat styles for superior results. Safety features include an Oxygen Depletion Sensor (ODS) that monitors air quality and an accidental tip-over shut-off to prevent hazards. The ignition system uses a push-and-rotate knob to light the unit reliably.
