Infrared gas grills exclusively use burners made to produce infrared heat rather than the convection heat found in traditional gas grills. This infrared heat travels in safe, directional waves, cooking faster and hotter while helping food retain moisture. Some grills offer one infrared burner, while some models are all-infrared. Though infrared grills are typically known for their high-end temperatures, there are some all-infrared grill brands like TEC Infrared Grills and Lynx Grills that have a fairly large heat range.
