  • Your kitchen doesn’t get hot as there is minimal extra heat created from the burner.
  • Liquids don’t burn to the cooker as it is not magnetic. This makes it easier to clean.
  • It is unlikely that you will burn a surrounding item as the cooktop doesn’t get hot.
  • Induction is a highly efficient cooking option.
  • Induction cookers cook your food very quickly due to the direct heat.
  • Due to this faster cooking rate, you save more energy, time and money.
  • Induction cooktops are very sensitive to temperature adjustments, allowing you to cook your food with more precise control.
