Pull the patio season later into the year with a 41,000 Btu propane heater that warms a 13-foot radius for up to 10 hours on one tank. A faux stone concrete finish lifts the aesthetic above utility-grade heaters, while the upgraded metal hood radiates heat downward and an adjustable flow valve fine-tunes the warmth. Four universal wheels plus a waterproof Pvc cover make it easy to move and protect between uses.
