To sear a steak you need direct radiant heat. I don't care if you can heat the air to 1000°F, it is still indirect heat and that does not deliver as much energy as direct radiant heat. It's physics, but not hard to understand. In short, heat is not the same as temperature. It feels hotter at 80°F if the sun is shining on you than if it is 80°F in the shade. I discuss the concept in more detail in my article on thermodynamics of cooking.
Apart from the replacement parts for a pellet smoker, there are also certain accessories that one can use to increase the range of its usefulness as well as improve its performance. A user can attach a griddle attachment to a pellet grill to use it as a flat top griddle, or use a hopper extender to increase the pellet hopper capacity; there is an attachment for every purpose to suit all of your needs. Let’s take a look at the types of accessories commonly found:
Most grills feature a primary cooking area (the main grate) and a secondary cooking area (additional racks). In a pellet grill, there’s less difference between the two grilling areas because it mainly cooks by indirect heat, so the temperature is the same throughout the grill. It’s best to pay attention to a pellet grill’s total cooking area because it is the sum of the primary and secondary cooking areas.
