A:AnswerThank you for your interest in the LG Cooktop. The LG CBIH3013BE induction cooktop cannot use all 4 elements at their maximum wattage/power level concurrently. The cooktop is designed to provide flexible power levels across the 4 burners, but does not appear to have the capacity to run them all at peak performance simultaneously.

A:AnswerThe 21" depth showing in the images for the LG 30" Built-in Electric Induction Smart Cooktop with 4 Elements and UltraHeat™ 4.3kW Power Element - Black Ceramic, Model # CBIH3013BE, is the depth for the unit itself (actual depth is 21 1/16"), and 28 1/2" is the cut-out width which is the precise, side-to-side measurement of an opening in a countertop designated to fit the cooktop...^Ivan.
A:AnswerHi there. Thank you for reaching out to us. We understand your inquiry regarding the heating technology of the CBIH3013BE Induction Cooktop. Based on the specifications for this model, "continuous simmer" technology is not listed as a feature, which indicates it typically cycles on and off to maintain low temperature settings.
