A:AnswerHello Raji - Thank you for the excellent question. This cooktop has two power boil burners and the left burners are 9500 BTUs. Using three burners at once will not be a problem. We just recommend sizing the pots right. If the cookware is too much larger than the burner, the boil time will be extended. Keep in touch! - JB
