The Char-Broil Heatwave Infrared cooking system is yet another breakthrough from the grilling minds at Char-Broil. The Heatwave system works using two troughs to transfer the radiant heat from the burners to infrared heat that cooks your food. The design is a unique, patented system, that provides 100% infrared heat. You can use wood chips in the troughs to indirectly cook food or just add smokey flavor and because of the design you don't get flare up and charring. Once again, the infrared technology is highly efficient and allows just three burners and 35,400 BTUs to provide all of the energy you need with this grill and its 550 square inches primary cooking area. A cooking guide is included on the side shelf of the grill to help fully utilize this ground breaking technology and as expected the other shelf features a flush mount side burner. The Heatwave grill also included integrated electronic ignition, a pull out tank tray, and Char-Broil's patented Dual Fuel system for easy conversion to Natural Gas. The cart has a closed look with metallic porcelain top and matching doors.
