What is a Pellet Grill? Working, Anatomy And All Parts Explained

A pellet grill is a cooking appliance that burns wood pellets to grill food. Wood pellets are made from compressed sawdust from hardwood trees and are a byproduct of sawmills. You need to load the pellets into a hopper, which feeds them into a firebox. 

The firebox has a heat source, such as charcoal or propane, that heats the pellets until they begin to smoke and ignite.

Moreover, the firebox has a fan that circulates air through the grill. It allows you to cook food at lower temperatures than would typically be with traditional charcoal grills or gas grills.

How Does a Pellet Grill Work?

Cooking with a pellet grill is simple, but it can often be confusing. The following steps will help you to understand exactly how a pellet grill works:

  • You will need to start by filling the hopper with pellets of your choice. After that, turn on the unit and allow it to preheat for at least 15 minutes. It is necessary, so the heating element can reach its optimum temperature, which helps ensure even cooking throughout your food.
  • Once your grill reaches a temperature of about 250 to 270° Fahrenheit, you can add meat or veggies to one side of the grates and close the lid. You should cook them until they reach an internal temperature of 180° Fahrenheit (which will take about 30 minutes). You can check this by using an instant-read thermometer or pressing down on them with tongs until they squish like a ripe peach.
  • After removing your food from the grill, let it rest for 10 minutes before serving, so all those tasty juices stay inside your meat. 
What is a Pellet Grill and how it works

The components of a pellet grill include the following:


The auger spins at high speed, feeding pellets from the hopper into the unit’s firebox, where the flame burns them.

It is connected to a motor that drives it to turn in either direction at variable speeds depending on how long you hold down on your controller button.

Auger helps regulate the temperature within your smoker or grill, so it always stays consistent when cooking different types of food.




A controller is like the brain of your smoker, telling it when to fire up, how much heat to generate, and when to shut down.

Some controllers feature WiFi connectivity, so you can monitor and control your smoker from anywhere with an Internet connection.

Others have a digital readout showing your grill’s current internal temperature.


A fan is present to spread the heat evenly over the cooking surface. It allows air to flow through the burners, which helps the pellets burn properly.

You can mount it directly on top of the burn pot or place it at a distance from where it distributes heat.



The chamber is the heart of the pellet smoker and produces the smoke. It has two essential parts: the firebox at one end and a water pan on the other end.

Firebox: The firebox is where wood pellets are added and ignited. The firebox may be made from steel or stainless steel, but it typically has an insulated lid to protect against heat loss.

Water pan: A water pan sits between the firebox and the main body of the smoker. It absorbs heat from the firebox and helps regulate temperature by providing a cool surface for moisture to condense on.

The Firepot is where you put your wood or charcoal, and depending on what type of grill you have, it either burns down to ash or burns until all of its fuel is over.

It also has an opening at its base for adding wood chips. The Firepot can be of cast iron or stainless steel, depending on how much heat you want to throw at it.




Hooper is where you put the wood pellets for use by an auger-driven pellet smoker or grill.

Some models have hoppers that require you to refill them manually, while others have automatic refills triggered by sensors when they get low on fuel or empty.

Each model has its way of doing things, but all serve the same.

How Do Traeger Grills Work?

In your Traeger wood pellet grill, you feed the wooden pellets in the hopper. The auger then moves these pellets from the hopper to the Firepot, where the HotRod lightens them to give aroma-rich flames to the meat in the grates. 

There is a fan to distribute the smoke in the grill evenly, so you get the same juicy taste from every meat segment. You can adjust the temperature by using the controller to cook like a professional pitmaster. A drip tray is there to prevent your food from flare-ups.

Does A Traeger Grill Need Electricity?

A Traeger grill is a pellet grill that uses electricity to power the fan, which blows air over the pellets to create heat. The grill then cooks your food using this heat.

It lets you control exactly how much heat you want in your food. You can cook at lower temperatures for longer periods or at higher temperatures for shorter periods.

Difference Between A Pellet Grill And A Gas Grill?

So you may have heard about pellet grills, or maybe you are already an enthusiast. But what is the difference between a pellet grill and a gas grill? The fuel source is a significant difference between the two.

A pellet grill burns wood pellets made from compressed sawdust and other natural materials, while gas grills burn propane or natural gas.

Pellet grills have some dissimilarities to charcoal grills and gas grills because they do not burn as hot as either of those two types of grills. They are also capable of much lower temperatures than charcoal or gas grills can achieve.

Pellet grills use wood pellets instead of gas or charcoal. There is no need for messy ash and charcoal cleanup after each use (though some people prefer to use wood). Once you are done cooking, you are only left with the food that was not consumed.

Final Words

We hope this post has helped you understand: what is a pellet grill? If you like the mild woodsy flavor of cooking with wood pellets, you may consider upgrading to a pellet grill. For those with enough space, a pellet grill would be a great addition to your backyard cooking arsenal.
