Warm an outdoor seating circle with this gray standing propane patio heater and its 48,000 BTU burner. The aluminum reflector directs heat downward across a manufacturer-stated 20-foot diameter, while a stainless steel burner handles the flame. Press-and-twist ignition starts the unit, and a knob adjusts the output. Tip-over, oxygen-depletion and flame-out protection are listed in the source; shutoff activates when the post tilts beyond 45 degrees. Wheels help move the 31-lb heater around a patio or garden, and ground stakes can secure its base after placement. It uses a propane cylinder that is not included. The reflector measures 32.5 inches across and the assembled post is 86 inches high. Assembly is required.
