This is the outdoor patio heater that generates high-output heat from biomass to offer a more efficient, convenient, and economical alternative to propane heaters, electric heaters, or firepits. Fueled by inexpensive, readily available wood pellets, the free-standing heater puts out 106,000 BTU over a 10-foot heating radius—up to three times the heat of propane or wood-burning models. It does not emit smoke, embers, or sparks and eliminates the hassle of exchanging unwieldy propane tanks as well as the sooty mess of wood-burning campfires or firepits. Constructed from heavy gauge steel with a rust-resistant powder coated finish, a German glass viewing window, coated temperature gauge, and adjustable feet for uneven surfaces. Double hopper holds 20 lbs. of wood pellets that provides 3-4 hours of burn time. Assembles easily without tools. 76" H x 22" W x 12" D. (55 lbs.)
