An infrared grill is a gas grill that uses infrared technology as the heat source or as an optional burner. In a conventional gas grill, the flame heats the grates directly. But in an infrared grill, there is an infrared element between the grates and the flame. The gas heats the infrared element, which then radiates intense heat to the food.
TEC claims it introduced the first radiant gas grill in the early 1980’s, using small flames to heat ceramic plates; the plates emitted infrared energy that cooked the food. Under the grates of TEC’s latest infrared system are glass panels directly over stainless steel burners.
