  • Precautions while using Induction Cooker

    Inadequate Power

    This is not a valid negative but we list and discuss it here because there are so many falsehoods and misunderstandings floating around on this matter. As we clearly showed, with hard numbers, induction cooking units are not merely as powerful as even pro gas ranges (residential pro, that is), they are almost invariably much more powerful. (And thats using conservative figures for both gas and induction efficiencies.) To recap, a top line (and top price) so called pro home gas range might have burners each rated at 15,000 BTU/hour or, in a few cases, as much as 18,000 BTU/hour but that is only about 2.1 to 2.5 kW for induction elements, and even the most modest cooktops have at least one element of at least 2.4 kW (and many have elements up to 3.6 or 3.7 kW or even more!). Any concern over the adequacy of the cooking power of induction units is simply silly and ignorant.
