The Electrolux Drop-In 30 in. amp Induction Hybrid Cooktop with Stainless Steel trim has two powerfully-efficient induction elements and two electric elements for the ultimate cooking flexibility. Induction cooking combines the power of gas with the easy clean-up of electric and offers more responsive temperature control at low and high heats so it is gentle enough to melt chocolate and powerful enough to boil water. And cooking with induction is 70% more efficient than gas and 20% more efficient than electric. Induction elements are compatible with most stainless steel and cast iron cookware. If a magnet sticks to the bottom of a pot or pan, it is induction-friendly.
