You want even grilling: One of the downsides of using a charcoal grill is ensuring that the entire grilling area is evenly heated. Spreading the charcoal evenly and avoiding hot spots is difficult. Traeger’s pellet grilling system overcomes this problem with a fan that evenly distributes the heat throughout the grilling area, much like a wood-fired oven would have.
Although these are marketed as grills, they do much more, including baking or roasting. Because they heat by convection, you might not get the grill marks that a gas or charcoal grill will give you, but you also won’t have the flame-up problems. While many pellet grills offer high cooking temperatures, the maximum depends on ambient temperature and wind. Many users wrap their grills in special insulating covers to help maintain heat, reduce fuel use, and reach the higher temperatures they desire.
