What is a Pellet Grill and How Does One Work?

Outdoor grilling has come a long way in a relatively short period.

We’ve come from the humble kettle design to big and fancy gas grills, and now we’re seeing innovations that sit somewhere in the middle.

The pellet grill design is a relatively new development and it’s an interesting one in both terms of flavor and how it works.

Pellet grilling might not be for everyone, but if you’re ready to try something new and want maximum flavor and the power of convection cooking, it might be for you.

What is a pellet grill and how does one work?

Let’s take a look and find out.

The Basics of a Pellet Grill

Unlike a traditional gas or charcoal grill, a pellet grill is mostly about indirect heat.

In this sense, it has a lot in common with a smoker.

The pellet system is offset to the side, and the heat comes from below but isn’t as immediate or direct as with a gas or charcoal grill.

The heat moves into the main grilling area where it circulates, infusing smoke flavor as the food cooks.

Considering the movement of hot air in the rounded grill body, it is also something of a convection oven.

What we have in the end is a smoker-grill-oven hybrid.

It might sound a bit complicated, but the specifics of how it applies the heat aren’t the most important thing.

It’s all about the performance and the cooking results.

A Pellet Grill Uses Wood as Fuel

What is a Pellet Grill?

Like a smoker, a pellet grill uses natural hardwood as fuel.

Only, instead of using wood chips or chunks, the wood is formed into a consistent pellet.

There are a few benefits to this…

  • Pellets, being consistent, provide a constant temperature that is easy to manage.
  • The wood creates smoke as well as heat, so food tastes richer and more complex.
  • There are several different types of pellets available using different wood varieties.
  • Flavors can range from the light smoke of Oak to heavier options like Hickory and Mesquite.
  • Pellets burn conveniently with less ash than large chips and chunks.

Pellet fuel is a solid fuel that requires no electricity.

You don’t need gas and pellets can be stored for years if they are kept away from moisture (they should be in an airtight bag or container).

Pellet grills can be used when the power is out, or when the weather isn’t the best and you can’t get to a gas station to refill or swap a canister.

How do the Mechanics Work?

What is a Pellet Grill?The mechanical function of a pellet grill is quite interesting.

There’s a hopper and feeder system used to load pellets into the main cooking and heating area.

The hopper is where the fuel goes.

You simply fill the hopper as needed and it uses a motor-driven auger to deliver the pellets to the combustion area.

A fan is used to feed oxygen into the grill.

Temperature is detected electronically, so it’s very easy to set the exact temperature you need and keep it there.

The best pellet grills have electronic thermostats that act rapidly to change the flow of air or pellets to get the desired temperature.

It’s quite advanced and is more complex than a traditional grill, but the result is consistent heat and convection.

Ultimately, you get food that tastes better and is cooked more thoroughly, no matter the doneness you’re aiming for.

Is There a Downside to Pellet Grilling?

Some pellet grills can produce a direct flame, and these allow for temperatures up to 700°F or 371°C, like what you would have on a stovetop or inside your home oven.

However, these temperatures are much lower than the hottest charcoal grills which can get above 1000°F or 537°C.

However, in practical terms, this type of heat is rarely needed.

The major downside is that you won’t be able to sear as well as you could on a traditional gas or charcoal grill.

It’s a tradeoff, but one that many buyers are willing to overlook.

After all, you can infuse smoke flavor without actually using a dedicated smoker or a wood chip box.

Pellet grills also have more moving parts, so they aren’t as durable as a charcoal grill, but are comparable in reliability to gas grills.

Stick with a well-known brand and you’ll enjoy good reliability throughout the warranty period.

How Long Can a Pellet Grill Run For?

Just like a charcoal grill or a wood smoker, the running time depends on a few factors.

  • The quality, size, and density of the pellets will influence the total burn time.
  • Pellets in the hopper will eventually deplete.
  • Higher cooking temperatures will consume fuel faster.

The variables mean it’s not easy to give a concrete answer, but most home grillers can expect to burn up to 3/4 of a pound of fuel every hour, or a little less if slow cooking at lower temperatures.

What are the Key Advantages of Pellet Grills?

We’ve touched on a few of the main advantages of pellet grilling, but it’s important to reiterate them so that you can make the best decision when you’re looking for an outdoor cooker.

  • Pellet grills offer versatility and can perform like convection ovens so potential ingredients and recipes are greatly expanded.
  • You can enjoy the real smoke flavor.
  • Temperature is easy to set and maintain. It’s done electronically so consistency is a major factor.
  • Grill starting is electronic, just like a gas grill. You don’t need matches, a lighter, or complex starting procedures.
  • The combination of smoke and convection creates a flavor that many would consider superior to standard grills.
  • If you want a smoker and a grill, purchasing a pellet grill instead could save you a lot of money.

With all these benefits in mind, and understanding how a pellet grill works, it’s time to consider some of the best options available today.
