Ideal for the indoors and outdoors alike, the Dura Heat LPC80 Propane Convection Heater is a wonderfully warm option for camping, outdoor construction, and warehouse work. This round convection heater radiates heat in a full 360-degrees, affecting up to 1,900 square feet. A variable temperature gauge lets you adjust the output between 50,000 and 80,000 BTUs. No electricity is required to power the unit, just a standard 40-lb. liquid propane tank which allows the heater to operate for a maximum of 17 hours. A 10-foot hose and propane regulator are included.
