Guide Review - Broil King Imperial 590 Gas Grill

The Broil King Imperial is a combination of stainless steel, sheet metal, and cast aluminum that make this grill much more like its competitors while retaining all the features that make Broil King some of the best cooking grills on the market.

The two features that stand out on this grill are 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 give 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 features a full rotisserie system that includes a standard (not infrared) 15,000 BTU rear mounted burner. This burner works as well as most any infrared rotisserie burner but has the durability of a high-quality stainless steel burner. There is also a stainless steel 10,000 side burner on the left side table under a flush mounted cover. This burner is a little low on the BTUs so it won't quickly heat up a large pot, but it is powerful enough to heat a small skillet or saucepan.

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 $1,400USD.
