2. Induction Cooktop FAQ

1.What’s an induction cooktop?

Induction cooking uses electromagnetic coils to transfer heat directly from the heating element to compatible cookware. This stands in contrast to traditional electric and gas cooktops, which use conduction and radiation, respectively, to heat a pot or pan. With induction, temperature changes are rapid, and less heat is lost to dissipation than with conduction or radiation. The result is faster cooking and more efficient energy usage, making induction cooktops an increasingly popular alternative to electric and gas stoves, thanks to their speed and efficiency.

2.Are induction cooktops safe?
Unlike an electric or gas cooktop that creates a heated surface or an open flame, an induction cooktop can only transfer energy directly between the heating element and compatible cookware (more on compatibility below). This makes induction cooktops safer than electric and gas stoves by design. Since there’s no open heat and the induction elements heat up and cool down rapidly, there’s far less risk of accidentally burning yourself than with a gas or electric burner.

Also, induction heating elements automatically shut off when a pot or pan is removed from it due to how induction works (that is, via direct contact between the burner and the cookware). Of course, hot food and cookware can still cause burns, so using an induction cooktop is not an excuse to be more careless than you would with an electric or gas stove.

3.What kind of cookware do I need for an induction cooktop?
Since induction cooktops use electromagnetism to transfer heat, only certain types of cookware – namely, that with a magnetic base – will work. “Begin by going through your existing pots and pans to double-check that they’re compatible with induction equipment,” advises Dean Harper. “They must contain iron to work – cast iron and magnetic stainless steel can work well, but aluminum or copper-based cookware will not work unless they have a magnetic base.”
Additionally, consider the sizes of the cookware if you’re buying new pots and pans for an induction cooktop. The sizing doesn’t have to be exact, but due to how induction works, a pot or pan that’s too large or too small for a burner won’t activate the heating element.

4. What regular maintenance or cleaning is required for an induction cooktop?
Another advantage induction cooktops have over electric and gas stovetops is that they are easier to clean. Induction cooktops typically feature slick glass surfaces that can be easily wiped clean. For more stubborn messes, you can use a glass-safe cleaning solution, gentle scraping tool, or soft brush.

Also, take care to keep any vents and air outlets clear of dust, grease, or other accumulations. Aside from cleaning, induction cooktops generally require very little, if any, maintenance on the part of the user. However, a professional electrician should always perform any required repairs or maintenance.

5. How long do induction cooktops last?

As simple and reliable as the best Induction cooktops can be, they don’t last forever and may begin to lose their cooking power and efficiency with age. Whereas the lifespans of most home appliances are measured in years, the operational expectancy of induction cooktops is measured in hours. You can expect a good induction cooktop for home kitchens to last around 10,000 hours of runtime. That equates to 8-12 years of life, depending on your cooking habits. Note, however, that the power efficiency of an induction cooktop may begin to wane before that 10,000-hour mark.
