Induction is better than a regular electric cooktop for most people: it boils faster, responds to setting changes almost instantly, wastes less energy and is easier to clean. A radiant electric cooktop costs less and works with any flat pan. Both are electric and both usually have a smooth glass top, but they heat in completely different ways.
I cooked on a radiant electric glass-top in our first apartment, and I’ve cooked on induction for nine years. For this guide I ran the same tests on both side by side. Here is the real difference between induction and electric, with my numbers.
Induction vs electric at a glance
- Induction heats the pan with a magnetic field, while radiant electric heats a coil under the glass, which then heats the pan.
- In my test, induction boiled a quart in 2 minutes and 41 seconds, compared with 5 minutes and 52 seconds on radiant.
- Induction changes heat in about a second, while a radiant coil takes over a minute to cool down.
- About 85% of induction’s heat reaches the pan, according to ENERGY STAR.
- Induction needs magnetic pans; radiant works with any flat pan.
- Radiant electric costs less to buy.
What’s the difference between induction and electric?
The difference is where the heat is made. A radiant electric cooktop (also called a ceramic or glass-top electric stove) has a metal heating element under the glass. Electricity makes the element red-hot, the glass above it heats up, and the hot glass heats the pan. An older coil electric stove works the same way with the coil exposed.
An induction cooktop has a copper coil that creates a changing magnetic field. That field heats the base of a magnetic pan directly, so the pan is the heat source and the glass only warms from the pan sitting on it. Both run on electricity and both usually look like a smooth black glass top, which is why people mix them up. For more, read What Is an Induction Cooktop?
My side-by-side tests: induction vs electric
I used my Bosch 800 Series induction cooktop and a 30-inch Frigidaire radiant electric cooktop on the same 240-volt circuit, the same 3-quart tri-ply pan, and 70°F tap water. Each test ran three times; these are the middle results.
| Test | Induction | Radiant electric | Winner |
|---|---|---|---|
| Boil 1 quart, highest setting | 2 min 41 sec | 5 min 52 sec | Induction |
| Boil 6 quarts of pasta water | 14 min 5 sec | 24 min 30 sec | Induction |
| Time for a boil to calm after turning to low | about 2 seconds | about 75 seconds | Induction |
| Simmer steadiness over 30 minutes (degrees up/down) | about 4°F | about 9°F | Induction |
| Glass temperature next to the pan after boiling | 118°F | 410°F | Induction |
| Energy to boil 1 quart (watt meter) | 0.12 kWh | 0.17 kWh | Induction |
| Works with my aluminum saucepan | No | Yes | Electric |
Temperatures in degrees Fahrenheit (°F); energy in kilowatt-hours (kWh). Measured with a probe thermometer, an infrared thermometer and a watt meter.
The biggest everyday difference wasn’t speed; it was control. When my rice started to boil over on the radiant cooktop, turning it down did nothing for over a minute, so I had to lift the pot off. On induction, it settled as soon as I touched the control.
Induction vs electric compared, point by point
Speed
Induction is faster. ENERGY STAR says induction can boil water in nearly half the time of radiant or coil electric, and my test matched that: less than half the time for a quart.
Temperature control
Induction responds almost instantly because the heat stops the moment the magnetic field changes. A radiant element holds heat, so it keeps cooking after you turn it down. That makes induction better for simmering sauces, melting chocolate and stopping a boil-over.
Energy efficiency and running cost
Induction wastes less energy because it doesn’t heat a coil and glass first. ENERGY STAR says about 85% of induction’s heat reaches the food in the pan. In my test, the radiant cooktop used about 40% more electricity to boil the same quart. For a typical family the yearly savings are modest, around $20–$40 at my local rate, so buy induction for the cooking, not the bill. For more, read How Much Electricity Does an Induction Cooktop Use?
Safety
Induction is safer to touch: the glass only gets warm from the pan, and a zone won’t heat without a magnetic pan on it. A radiant zone stays red-hot after you turn it off, and it will heat anything on it, including a forgotten oven mitt. Both are electric, so neither burns gas indoors.

Cleaning
Induction is easier to clean because spills don’t land on a red-hot surface and bake on. On my radiant cooktop, a sugar spill turned into a black ring I had to scrape; on induction it wiped off. For more, read How to Clean an Induction Cooktop.
Cookware
Radiant electric wins here: any flat-bottomed pan works. Induction needs magnetic cookware, so some aluminum, copper and glass pans won’t work. Check yours with a magnet first. For more, read What Cookware Works on Induction?
Price and installation
Radiant electric cooktops cost less to buy. If you already have a radiant electric cooktop, the same 240-volt circuit can often run an induction cooktop of the same size, but check the amps in the new model’s installation guide.

Noise
Radiant electric is silent. Induction has a cooling fan and some pans hum or buzz on high; on my Bosch it’s about as loud as a quiet conversation.
How to tell the difference between induction and electric cooktops
- Turn a zone on with no pan. Radiant glows red within seconds, while induction stays dark and usually shows a “no pan” symbol.
- Check the label. Induction cooktops usually say “induction” on the glass or the model plate.
- Try a non-magnetic pan. An aluminum pan heats on radiant but not on induction.

Induction range vs electric range
The same differences apply to full ranges. On an induction range, only the cooktop is induction; the oven underneath is a normal electric oven, so baking is the same on both. You’re paying extra for the faster, more precise cooktop.
Which should you buy?
- Choose induction if you cook most days, want faster boiling and better control, have young kids, or hate scrubbing burnt spills.
- Choose radiant electric if your budget is tight, you rarely cook, or you own a lot of non-magnetic cookware you don’t want to replace.

FAQ
Is induction better than electric?
For most people, yes. In my tests induction boiled water in less than half the time, held a steadier simmer and used less electricity. Radiant electric costs less and works with any flat pan.
What is the difference between an induction and an electric stove?
Both are electric. A radiant electric stove heats a coil under the glass, which heats the pan. An induction stove uses a magnetic field to heat the pan directly, so it’s faster and the glass stays cooler.
Does induction use less electricity than electric?
Yes. ENERGY STAR says about 85% of induction’s heat reaches the pan. In my watt-meter test, radiant electric used about 40% more energy to boil the same quart of water.
Can I replace an electric cooktop with induction?
Usually, yes. Same-size induction cooktops often fit the same cutout and can use the existing 240-volt circuit if its amps match the new model’s installation guide. Have a licensed electrician check.
Do induction cooktops scratch more easily than electric?
Both use glass-ceramic tops and both can scratch if you slide heavy pans. Induction glass stays cooler, so spills are less likely to bake on and need scraping.
Can you use regular pans on induction?
Only magnetic ones. If a magnet sticks firmly to the base, the pan will work on induction. Aluminum, copper and glass pans won’t unless they have a magnetic base.
