Induction and radiant smoothtop cooktops both run on electricity, but they heat food differently. Induction heats compatible cookware directly, so it typically responds faster and leaves less residual heat on the glass. Radiant electric heats an element beneath the glass, which then heats the pan; it works with more kinds of cookware and often has a lower initial price. The right choice depends on your pans, cooking habits, budget, and the electrical and countertop requirements of your kitchen.
How induction and radiant electric cooktops work
Induction heats the cookware
An induction cooktop uses electromagnetic energy to generate heat in compatible cookware. Because the pan is heated directly rather than by a hot element under the glass, induction can respond quickly when you change the heat setting. Less heat is transferred to the surface by the appliance, although a hot pan can still warm the glass. The U.S. Department of Energy explains the basic distinction in its induction cooktop guide.

Radiant electric heats through the glass
A conventional electric smoothtop has a resistance element below the glass surface. The element heats the glass, and the glass transfers heat to the cookware. That surface and element can stay hot after you lower the setting or turn the cooktop off, so changes in heat are less immediate. Consumer Reports describes this difference in its induction-versus-electric comparison.
Induction vs. radiant electric at a glance
| Consideration | Induction | Radiant electric |
|---|---|---|
| How heat reaches the pan | Electromagnetic energy heats compatible cookware directly. | A resistance element heats the glass, which heats the cookware. |
| Heat response | Generally faster to raise or lower; less residual heat from the cooktop itself. | Slower to respond because the element and glass retain heat. |
| Cookware | Requires compatible cookware, usually with a magnetic base. | Works with flat-bottom cookware whether magnetic or not. |
| Initial price | Varies by model; some models may cost more. | Often offers a lower initial appliance price. |
| What to verify before installation | Cookware compatibility, appliance dimensions, and electrical requirements for the specific home and unit. | Appliance dimensions and electrical requirements for the specific home and unit. |
What the performance and efficiency figures mean
Consumer Reports said its tests found induction could boil water 20–40% faster than a typical electric cooktop. The Department of Energy repeated that finding in 2023, attributing it to Consumer Reports. It is a reported test result, not a guaranteed advantage for every model, pot, water volume, or kitchen setup.

ENERGY STAR’s archived emerging-technology material for 2021–2022 describes induction as 5–10% more efficient per unit than conventional electric resistance cooking. Separately, ENERGY STAR’s electric-cooking guidance says about 85% of heating energy is transferred to cookware on induction; that figure is presented in comparison with gas, not as a direct efficiency comparison with radiant electric. Neither figure predicts a particular household’s bill. Actual costs depend on electricity rates, cooking habits, appliance models, and purchase prices, and the cited material does not establish a universal lifetime saving for either type.
A separate statistic is sometimes mistaken for a performance measure: the Department of Energy reported that nearly 70% of respondents in a Consumer Reports survey from June 2022 said they would consider induction for their next range or cooktop. That reflects stated consideration in that survey, not purchases or current consumer preference.

Advantages and tradeoffs of induction
Why it may suit your kitchen
- Quick, responsive heat: Directly heating the pan makes it easier to adjust promptly when bringing water to a boil, reducing heat, or moving between cooking tasks.
- More control at low heat: Consumer Reports has reported strong low-temperature control in its product testing, although results vary by model.
- Less residual surface heat: The cooktop itself generally contributes less heat to the glass than a radiant element does. This can reduce the chance of lingering heat from the appliance, but it does not make the surface burn-proof.
- Potentially less wasted heat: Heating cookware directly can reduce heat transferred to the surrounding surface. Household energy savings are not guaranteed.
What to consider
- Some pans will not work: Induction requires compatible cookware, and stainless steel is not automatically compatible.
- Cooking may feel different: The quick heat response can take adjustment if you are used to radiant electric.
- Price is model-specific: Prices and features vary. Compare actual models rather than assuming every induction cooktop carries the same premium.
Advantages and tradeoffs of radiant electric
Why it may suit your kitchen
- More cookware flexibility: Flat-bottom cookware can work whether or not it is magnetic, which may let you keep pans that induction would not accept.
- Often lower initial price: Radiant models often cost less up front, but prices vary by model and market.
What to consider
- Heat lingers: The glass and element take time to cool after cooking, so the surface can remain hot after you switch off the heat.
- Heat changes are less immediate: The retained heat can continue cooking food after you lower the setting. Simmering performance varies from one model to another.
Check your cookware before choosing induction
- Test the pans you use most: Hold a magnet to the bottom of each pan. ENERGY STAR’s practical guidance is: “If the magnet sticks to the cookware, it will work with induction.”
- Check the manufacturer’s compatibility information: Pan construction varies, so verify the specific cookware rather than relying only on a material label. Cast iron, enameled cast iron, and some stainless-steel pans are common compatible examples.
- Decide whether to replace any incompatible pans: Include that cost and the inconvenience of changing cookware in your comparison. If keeping your current nonmagnetic pans matters more, radiant electric is the more flexible option.
Choose based on how you cook and what your kitchen needs
- Lean toward induction if quick response, low-heat control, or less residual heat from the cooktop is important and your pans are compatible—or you are prepared to replace some.
- Lean toward radiant electric if you want to keep flat-bottom pans that are not magnetic or put a lower initial appliance price first.
- Compare specific models for burner layout, controls, size, and tested performance. A category label does not tell you how a particular cooktop simmers or fits your cooking routine. Consumer Reports’ induction cooktop guide was updated September 14, 2026; its electric cooktop guide also covers tested models.
- Consider your daily habits: Think about whether faster cooking, steady heat for sauces, concerns about accidentally burning food, children or pets near the cooking area, and adapting to a different heat response matter to your household.
Plan the cooktop installation before buying
For a construction or renovation project, confirm the fit and service requirements before selecting a unit. Check the countertop cutout dimensions, the appliance installation documentation, and the home’s electrical requirements against the exact model. Consumer Reports says the electrical requirements and installation are the same when replacing an old electric cooktop with induction, but that general statement should not replace verification of the appliance and the actual site. If the project involves new wiring, a different layout, or uncertain existing service, have a qualified professional assess it before the countertop or cabinetry is finalized.

Safety and care for glass cooktops
Induction usually leaves less heat from the appliance itself on the surface when no pan is present, and many models detect cookware or stop heating when it is removed. Features differ by model, and heat from a hot pan can still warm the glass. Radiant smoothtops can retain heat after the element is off. Check the safety features in the documentation for the model you are considering, and treat either type of glass surface as potentially hot during and after cooking.
ENERGY STAR cautions that glass or ceramic tops can scratch or crack. Avoid abrasive scouring sponges, and take care not to drop heavy cookware or drag it across the surface.
