Big Buddy Radiant Propane Heater - 18,000 BTU

The Mr. Heater Big Buddy radiant heater, delivers safe, quiet, and odor-free warmth for chilly garages, tents, patios, porches, and cabins. This lightweight and portable unit offers three adjustable heat settings—4,000, 9,000, or 18,000 BTU—controlled via a large 4-position knob with a built-in piezo starter. It is equipped with multiple safety features, including a built-in protection probe, an accidental tip-over safety shut-off, and an automatic low oxygen shut-off system (note: a low oxygen sensor prohibits its use at altitudes of 7,000 ft or above). The heater is CSA listed and can be powered by either one or two 1 pound propane cylinders or a larger tank using an optional 5 ft or 12 ft hose, providing a runtime of up to 108 hours on a single 20 pound tank. An integrated blower fan, powered by an A/C adapter or four "D" cell batteries, helps circulate the heat.
