Pros and Cons of Induction Cooktops and Ranges
Consumer Reports has no financial relationship with advertisers on this site.
The power and precision of the technology comes from an electromagnetic field below the glass cooktop surface that transfers current directly to magnetic cookware, causing it to heat up.
Essentially, induction cuts out the intermediate step of heating up a burner and then transferring the heat to the pot.
Home cooks have been warming to induction because it cooks faster and responds much faster when you dial back the temperature.
And prices have been dropping, with some induction ranges selling for $1,000 or less. Induction cooktops and ranges still tend to cost more than electric smoothtops, but the difference in performance is significant. If youre thinking of making the switch, heres what you need to know.
What Induction Isand What It Isnt
Induction ranges look a lot like typical glass-top electric ranges. The biggest difference youll notice is that because the electromagnetic field on an induction cooktop doesnt create a glow, you wont know its on. Thats why manufacturers have started adding virtual flames and other lighting cues.
As for the ovens in induction ranges, they broil and bake the same as other electric ovens.
The Induction Advantage
No other cooking technology that weve tested is faster than the fastest induction elementswere talking 2 to 4 minutes speedier than the competition to bring 6 quarts of water to a near-boil. Life-changing? Probably not.
Contrary to popular belief, induction cooktops can get hot, but the heat is transferring from the cooking pot to the glass through conduction, much as a hot pan would transfer some heat to a countertop if you set it down to rest. As soon as you remove the pot, that heating stops. And because the heat is going from the pan to the cooktop, the glass surface never gets as hot as it does on a traditional radiant electric range. And if you turn an induction burner on with no pot on it by mistake, it wont get hot, a nice safety feature.
You Need the Right Cookware
If youre shopping for new cookware, look for pots and pans marked induction-compatible. If you want to know whether your existing arsenal of cookware will work with an induction range, use a magnet to see whether it strongly sticks to the bottom of your pots. If it does, it will work on an induction burner.
Whats That Noise?
A buzz or hum is common and often is louder at higher settings, says Tara Casaregola, who oversees testing of ranges and cooktops for Consumer Reports. And we often hear clicking of element electronics at lower settings, as well as the sound of the cooling fan for the electronics. Heavy, flat-bottomed pans help reduce the vibrations that cause this buzz.
Dig Out Your Dial Thermometer
The magnetic field of an induction cooktop can interfere with a digital meat thermometer, so you may need an analog thermometeran old-fashioned solution to a modern problem.
