What is an Induction Cooktop? 5 Benefits of Making the Switch

One of the biggest selling points of the induction stove is speed. It simply takes less time to cook food because the pan surface heats up quicker. That's because while both gas stoves and electric cooktops use a middleman to transfer heat to the pan — flames and an electric burner, respectively — an induction cooktop generates heat directly in the pan.

Electromagnetic activity in the cooktop triggers electromagnetic energy in the pan, and the pan itself gets a rapid rise of heat (see How Induction Cooktops Work for more on this process). The pan is the starting point of the heat. Since there are fewer steps involved in heating the cookware, it takes less time for the heat to get to the food — 25 percent to 50 percent less time, on average.

It's this direct approach that gives induction most of its uniquely impressive qualities, including the one up next.

It's pretty easy to see why induction stovetops are more efficient than gas and electric models if you think about the heating processes involved. A gas flame is going to release lots of heat around the pan, and an electric burner emits radiant heat at any point where it's not in direct, firm contact with the pan. When heat is generated within the pan itself, as with induction, more of that heat gets to the food, and less of it warms up your kitchen.

The most obvious result of energy efficient cooking options is reduced energy consumption, meaning lower power bills and a healthier environment. The added benefit of this cooktop surface is that you won't sweat as much in the kitchen.

Another benefit of reduced accidental heat loss? The reduced possibility of accidents!

The stove top is easily one of the most dangerous places in the kitchen. It's where grease fires begin, where the gas gets left on, and where little hands make contact with very hot surfaces. So, let's start with the obvious: no flame means no grease fires, and no gas means no gas leaks.

But the induction stovetop has another safety feature: it typically doesn't get all that hot, since the pan is its own heat source. This means it would be far less likely for the cooktop to cause a burn. What's more, the pan's response to a turn of the dial is practically immediate, so as soon as you turn off the heat, the pan cools down.

This makes it a lot more difficult to burn yourself as you pour your sautéed vegetables onto a serving plate. It makes it easier to get those vegetables just right, too ...

For people who love to cook — or at least love to eat great home-cooked food — control is probably the most important feature of a cooktop. It's why many serious cooks prefer gas to electric: gas cooktops are more responsive when you adjust the dial. The temperature change is fast.

An induction appliance is as responsive as a gas cooktop to a turn of the dial, and it's got another thing going for it, too: more settings. Induction models allow for much more precise control of heat, with more temperature increments and better performance at very low heat settings. In this way, induction makes cooking delicate sauces or just keeping food warm a lot easier than with a gas flame, which can often falter on the low setting.

And finally, a benefit that rivals speed for practicality ...

Quicker cooking is great. Less wasteful, safer and better cooking is great. But cooking that's easier to clean up after is, we dare say, greater.

If the main purpose of your cooktop is to get dinner on the table faster and do it safer, it goes without saying that a quicker, less-intensive cleanup would be a big draw. Since an induction cooktop seldom gets very hot, food doesn't burn onto the cooking surface. This means a splatter, a spill, or a pasta-sauce pop calls for a quick swipe of the sponge, not a good, long scrub.

Even with ease of clean-up — even with speed, energy efficiency, safety, control and easy clean-up — induction surfaces may not overcome the price issue for some. They're still significantly more expensive than cast iron, gas and electric cooktop models, thanks to its copper coil and electromagnetic field construction. Factor in the new cookware you might need to buy, because your current stuff might not be induction compatible, and it's a big investment.

But if you're doing one of those increasingly popular $30,000 kitchen remodels, or even a $5,000 appliance upgrade, an induction cooktop should be at the top of your "look into" list — even, or perhaps especially, if all you do with your stove is boil water. Gas cooktops, electric cooktops and ranges may offer a lower price-point, but they're also costlier and more complicated to use than magnetic cookware.
