The Bottom Line

This dual head grill (two cooking chambers under two lids) from Broil King is the biggest grill they make and with a total cooking area of more than 1000 square inches, it is a monster. Solidly built with a full rotisserie system and side burner, this very big grill gives you a great deal of versatility. The advantage of the two cooking chamber design is that you can heat up the small portion of a couple of chops or the large one for bigger cookouts.

Or you can separate foods between the two sides. The disadvantage is, flipping two lids and the breakup of the large cooking area. You decide where you fall in this argument.

Guide Review - Broil King Imperial XL Gas Grill

This very large gas grill gives you two independent cooking chambers, one with 4 burners and one with 2 burners.

You also get a full rotisserie system with a rear mounted burner (not infrared) and a side burner (that is a little weak but still good). What this gives you is one of the most versatile gas grills on the market. You can operate the rotisserie while grilling steaks in the other chamber. You can grill hot and fast on one side and low and indirect on the other. If these advantages sound good to you, then this is an excellent grill for you to consider. If the two lids and divided cooking space don't appeal you might want to try the Broil King Imperial 90.

Mechanically the two features that stand out on this grill is the dual tube stainless steel burners and the linear flow control valves. The dual tube burners equalize the gas pressure inside the burner so that the heat is even front to back. Standard tubular burners tend to have higher pressure in the front of the burner and can give you uneven heating. The Broil King burners correct this problem.

The control valves on this grill have an even, highly precise flow that gives you a very high level of heat control. Add in the four burner design and this grill will let you pick an exact temperature from the very high to the very low.

This grill has great construction and should last for many years.

Broil King is known for making superior grills and this one is a good value at around $1,800USD.
