Manufacturer's rating of the maximum output of surface cooking burners, measured in British thermal units per hour (Btu/hr.). High-power burners (over 11,000 Btu/hr.) are intended for quickly heating large quantities, searing, and other high-temperature cooking. Medium-power burners (over 6,500 Btu/h and up to 11,000 Btu/hr.) are for general use, and low-power burners (6,500 Btu/hr and below, sometimes called simmer burners) are intended for delicate tasks such as sauces. However, we've found that many burners with medium and even high maximum output, when turned down to their low setting, performed well on our low-heat cooking tests. Such burners offer more flexibility for different cooking tasks than do dedicated simmer burners.
