Gimme a name! Different manufacturers use different names for heat deflectors - Flavorizer bar, heat tent, heat plate, Flame Tamer, burner tent or heat distribution shields. No matter what you call them, their purpose is the same.

Radiants and Flavorful Heat: Right above your trusty burner, you’ll often find a rock grate or metal tent bars in your gas grill. For some infrared models, it might be a large bin or tray. Their job is twofold: spreading that fiery heat evenly across the cooking surface and turning food drippings into that mouthwatering barbecue flavor. Now, that’s some tasty science in action!

Use, abuse, cleaning and replacement: Since these devices are the first defense in protecting your burners, they collect acidic food debris and grease. It’s a good idea to grab a putty knife and scrape them off when they start to get funky. Food drippings might be good for flavor, but a buildup of unburnt residue is hard on these parts. Over time and use, they will corrode, rust through, and need replaced.

Here’s a smokin’ fun fact for you: Did you know that smoking meat is one of the oldest cooking methods known to humankind? Smoking dates back thousands of years to our ancestors who discovered that exposing meat to smoke not only preserved it but also enhanced its flavor. Over time, this ancient preservation technique evolved into the delicious art of barbecue we know today, with regional variations and secret recipes passed down through generations.

Below, we explain the differences between these devices, and differences between the different organic radiant types.

They’re crafted from materials like aluminized steel, stainless steel, porcelain-coated steel, or cast iron. These plates work their magic by concentrating heat more efficiently than lava rocks or briquettes, meaning you can dial down the control settings. Plus, on some models they’ve got holes or slots that let heat rise evenly while vaporizing those delicious food drippings.

Ceramic Briquettes

Imagine self-cleaning magic in the world of grilling. These ceramic briquettes come in various shapes and sizes, from cones to pyramids. The heat from the burner flame keeps them spick and span. The uniform shape and size of these briquettes ensure top-notch heat distribution. They’re like the precision tools of grilling. Some are sold in a kit form that contains a stainless steel carrier along with briquettes.

Ceramic Rods in Radiant Tray

Primarily used in DCS (Dynamic Cooking Systems) Grills, Ceramic rods produce very even heat and flavor infusion under the grilling surface. The rods are tucked inside the radiant tray, which help provide ultimate protection for your burners. Over time the rods can become brittle and break, but are easy to replace and are in stock at

Lava Rock and Pumice Stone

Although we do not carry pumice stone or lava rock at, they are worth a mention here because of overall popularity.
Lava Rock is a classic choice for older grill and a budget friendly option. These lightweight lava rocks heat up in a flash and distribute heat pretty well. But here’s the thing – they’re super porous, which means they can get greasy and messy. You’ve got to change them yearly or when they’ve soaked up too much grease. If you neglect them, they might just catch fire and give you an out-of-control cooking experience – not the kind of fireworks you want at your grill party!
Pumice Stone: Here’s a rock with a twist – similar to lava rock but with a smoother surface and slightly higher cost. The less porous surface means it gets a thorough bake-off, resulting in fewer flare-ups. It’s like the lava rock’s classy cousin at the barbecue.

So, there you have it – radiants - your gas grill’s secret sauce for flavor and even cooking.
