To choose an induction range you should know the basics of how it works, what pots and pans are needed to make it work and then determine to what uses you will put it.
It works because the range elements or “hobs” as they are known generate a magnetic field which induces a current in an electrically conductive cooking vessel which makes the cooking vessel heat up. The heat loss is less than 10% because the range top does not become hot except where the hot cooking vessel rests. Both gas and electricity waste over three times this amount of heat because they burn gas or heat an electric element which in turn heats the cooking vessel in order to heat the food. Almost half of the heat from the burning fuel or hot element escapes into the air without heating the cooking vessel. This heats up the kitchen which makes the air conditioner work harder adding even more energy costs.
Since the range top does not heat up splatters do not burn making it easy to wipe down.
Choose pots and pans that will conduct magnetism. Some cooking vessels are made expressly for induction cooking although cast iron and stainless steel also work. A simple test is whether a small kitchen magnet will stick to the surface of the cooking vessel. If it sticks securely it can be used with the induction cooker. Determine which pots and pans you own will work for induction cooking and how many more you need to purchase.
Determine the purposes for which you will use the induction range. A large family will need to choose an induction range with higher wattage, more temperature settings, more hobs and an oven cavity. A gourmet cook may prefer to have up to 100 heat settings rather than the basic 3 settings. Married couples who cook less may need to choose an induction range with only two hobs.
When replacing a freestanding gas or electric range with induction decide if you also want to have the convection and warming oven features.
If you have limited space and don’t need to cook a lot of food at one time a 2 hob countertop unit with space requirements of less than 12in. wide may work.
Remember, implanted medical devices may react adversely to induction appliances.
Surfing the web and visiting dealers is your final step to choosing an induction range that is right for you.
