how many btu needed to cook a steak
But there are some magic numbers to look for. For a standard gas grill, look for about 80 to 100 BTUs per square inch, and 60 to 80 for an infrared grill like the Char-Broil TRU-Infrared Commercial 2-Burner Gas Grill ($215.20 with in-store pickup, a low by $54), which uses radiant heat.Once again, this supposes that the grill you buy is efficient and well made.n the one hand, you could spend as little as $68 for this two-burner gas grill at Walmart (with in-store pickup, a low by $107).
