When you're shopping for a premium grill, you'll notice that many top models mention infrared burners, especially side burners and rear burners. But what exactly is an infrared burner, and why should it matter to you? Understanding this technology helps you make a smarter investment in outdoor cooking equipment that will genuinely improve your grilling experience.
What Is an Infrared Burner?
An infrared burner works differently than a standard gas burner. Rather than heating the air around your food, an infrared grill burner emits radiant heat energy directly. Think of it like the warmth you feel from the sun: the heat travels in straight lines and warms whatever it hits.
Inside an infrared grill burner, gas flows through a specially designed chamber with a ceramic or metal surface. When the gas ignites, it heats that surface to extremely high temperatures. The hot surface then radiates infrared energy downward onto your food and grates, creating intense, focused heat.
This is fundamentally different from open flame burners, which warm the air and create indirect heat. That difference makes a real impact on how your food cooks.
The Advantages of Infrared Heat
There are several reasons why infrared technology has become a hallmark of premium grills.
Superior Searing Capability
Infrared burners reach much higher surface temperatures than standard burners. This means steaks, chops, and other cuts develop a perfect crust quickly while staying tender inside. The intense, direct heat seals the meat's exterior and locks in juices. You get restaurant-quality results at home.
Even Heat Distribution
Because infrared heat radiates evenly across the burner surface, hot spots are minimized. Your food cooks more uniformly, reducing the need to constantly move items around the grill. This consistency is especially valuable when cooking for a crowd.
Reduced Flare-Ups
Traditional burners create flare-ups when fat drips onto the flame. Infrared burners are less prone to this problem because the heat comes from a surface rather than an open flame. You spend less time managing flames and more time enjoying your meal.
Energy Efficiency
Infrared burners convert fuel to usable heat more efficiently than standard burners. You'll use less gas to achieve the same cooking results, which means lower operating costs over time.
Where You'll Find Infrared Burners
Manufacturers use infrared burners in specific positions to maximize their benefits. Understanding where they appear helps you choose the right grill for your cooking style.
Rear Burners
The rear burner is the most common placement for infrared technology. This position is ideal for searing because you can slide steaks or chops across the main cooking surface toward the back, then finish them with a quick sear. Napoleon's Prestige series, for example, features infrared rear burners on many models.
Side Burners
Side burners with infrared capability are perfect for searing as well. They let you heat a separate zone without affecting the temperature of your main cooking area. Premium grills like the Napoleon Prestige 665 come equipped with infrared side burners for versatile cooking.
Secondary Burners
Some high-end models feature infrared as an additional burner option alongside standard gas burners, giving you maximum flexibility.
Infrared Burners vs. Standard Burners
Both types have their place in outdoor cooking, but they excel in different situations.
Standard burners are reliable workhorses. They provide consistent, even heat across the cooking surface and work well for everyday grilling, roasting, and low-and-slow cooking. They're also simpler to maintain.
Infrared burners shine when you want high-temperature searing, fast cooking, or precise heat control in a focused zone. They're an investment in versatility and premium results.
Many of the best grills actually combine both. You might have standard main burners for everyday cooking and an infrared rear burner for searing steaks or finishing dishes. This hybrid approach gives you the best of both worlds.
Choosing a Grill with Infrared Burners
If you're shopping for a premium grill and infrared technology appeals to you, here's what to evaluate.
-
Determine your cooking priorities. Do you frequently sear meat? Do you want a dedicated high-heat zone? If so, infrared is worth prioritizing.
-
Check burner placement. Rear burners and side burners are most useful. Front burners are less critical because you're typically using the main cooking area.
-
Look at total heat output. Infrared burners should be powerful enough to make a noticeable difference. Check the BTU rating to ensure you're getting genuine high-heat capability.
-
Consider your budget. Infrared technology adds to the price. Premium grills from brands like Napoleon offer infrared at various price points, so you can find options that fit your investment level.
-
Read customer reviews. Real users will tell you whether infrared burners deliver on their promise and whether maintenance is manageable over time.
Maintenance Tips for Infrared Burners
Infrared burners are durable and reliable, but they do require basic care to keep performing.
- Clean the ceramic or metal surface regularly to prevent grease buildup, which can reduce heat output.
- Check for cracks in ceramic elements during off-season maintenance. A cracked surface should be replaced.
- Ensure the burner isn't blocked by debris or grease. Clear the area around the burner before each cooking session.
- Follow the manufacturer's maintenance schedule, which you'll find in your grill's documentation.
Proper care keeps your infrared burner working efficiently for years.
Final Thoughts
Infrared burners represent a meaningful upgrade for serious grillers who want precision, power, and versatility. They transform your ability to sear, finish dishes, and control heat zones. Whether you're drawn to a rear infrared burner for steaks or a side burner for searing vegetables, this technology delivers real value.
