Induction Hobs:
- Uses magnetic fields to directly heat pots and pans.
- Fast and energy-efficient, providing precise temperature control.
- Requires cookware with a ferrous (magnetic) base.
Halogen Hobs:
- Uses halogen lamps to heat the surface.
- Offers rapid heating with a smooth, flat design.
What Falls Under the Term "Electric Hob"?
- Coil Electric Hobs
- Ceramic Glass Hobs
- Induction Hobs
- Halogen Electric Hobs
- Vitroceramic (Glass Ceramic) Hobs (common in some European markets)
Electric hobs, in general, provide a controlled and clean cooking experience with options for different heating mechanisms. Whether it's the traditional coil design, the sleek ceramic surface, or the advanced induction technology, they all fall under the broader category of electric hobs.
Which is Better, an Induction or an Electric Hob?
An induction hob works similarly to an electric hob, but it has coils beneath its surface that induce electrical current to generate heat in the pan or metal object. It uses less power and remains cold until you place a pan on it, meaning it uses less energy than other types of electric hobs.

When choosing between an induction hob and a traditional electric hob, it's essential to understand their differences, how they work, and their specific advantages. Here's a detailed breakdown of each, followed by a comparison table to help make the decision clearer.
1. How Do They Work?
Induction Hob:
An induction hob uses electromagnetic energy to directly heat the cookware. Beneath the ceramic surface, there are coils that generate an electric current when the hob is turned on. This current interacts with the metal in the pan, causing it to heat up. As a result, induction hobs only heat the cookware, not the surrounding surface, making them more energy-efficient. The hob remains cool to the touch until a pan is placed on it, which reduces the risk of burns.
Electric Hob:
A traditional electric hob uses heating elements beneath the ceramic or glass surface. These elements heat up when electricity is passed through them, and they transfer heat to the pan. Electric hobs are slower to heat up compared to induction, and they continue to emit residual heat after turning off, making them less energy-efficient than induction hobs.
2. Energy Efficiency
Induction Hobs are more energy-efficient because the heat is directly transferred to the pan, using up to 90% of the energy produced. This results in faster cooking times and less wasted energy.
Electric Hobs are less efficient, typically operating at 70-80% efficiency. The heat is generated in the heating element and transferred to the pan, which takes more time and energy.
3. Cooking Speed and Control
Induction Hobs heat up instantly and offer precise temperature control. The cooking process is faster because the energy is directly transferred to the pan, which means quicker boiling times and better temperature consistency.
Electric Hobs, while effective, tend to take longer to heat up and cool down. Temperature control is less immediate, and the residual heat can sometimes make it difficult to control the exact cooking temperature.
4. Compatibility with Cookware
Induction Hobs require magnetic cookware. Only pots and pans made from ferrous metals like cast iron or certain stainless steel will work. Non-magnetic cookware like aluminum or glass won't heat on an induction surface.
Electric Hobs are compatible with a wide variety of cookware, including non-magnetic materials like aluminum, copper, and glass, making them more versatile in terms of the pans you can use.
5. Cleaning and Maintenance
Induction Hobs are easy to clean since the surface remains cool and spills do not burn onto the hob. Most food spills are simply wiped away, making maintenance straightforward.
Electric Hobs can be harder to clean, especially traditional coil models. Spills may burn onto the hot surface, requiring more effort to clean. Ceramic electric hobs are easier to maintain but can still leave stains if not cleaned immediately.
6. Safety
Induction Hobs are generally safer because the hob remains cool to the touch. The heat is only generated when the pan is in place, and most models have built-in safety features like automatic shut-off, child locks, and overheating protection.
Electric Hobs can remain hot even after being turned off. There's a risk of burns from residual heat, and they don't typically have the same level of safety features as induction hobs.
Are Gas Hobs Better than Electric?
Gas hobs are often favored by professional chefs due to their instant, visible heat control, making them ideal for techniques like searing and wok cooking. They also work with any type of cookware.
However, electric hobs, especially induction models, have distinct advantages. They heat up faster, are more energy-efficient, and provide precise temperature control. Additionally, electric hobs are safer, as they don’t have an open flame, and easier to clean due to their flat surfaces.
Are Gas or Electric Hobs Cheaper to Run?
Gas hobs are generally cheaper to run than electric hobs because natural gas is usually less expensive than electricity. Gas hobs offer instant heat but are less energy-efficient, with an efficiency of around 40-50%. On the other hand, induction hobs are much more energy-efficient (up to 90%) as they heat cookware directly, but they tend to have higher running costs due to electricity being more expensive.
In total, while gas hobs have lower running costs, electric hobs—especially induction models—offer faster cooking times, greater energy efficiency, and easier cleaning. The choice largely depends on whether you prioritize lower daily costs or energy efficiency and convenience.
| Factor | Gas Hobs | Electric Hobs (Including Induction) |
|---|---|---|
| Running Costs | Lower daily costs due to cheaper gas | Higher due to the higher cost of electricity |
| Energy Efficiency | Around 40-50% efficient | Induction: Up to 90% efficient; Electric: Lower |
| Speed | Instant heat, good for immediate cooking | Induction: Faster; Electric: Slower than gas |
| Cooking Precision | Less precise temperature control | Induction: More precise control |
| Cleaning | Harder to clean due to open flames | Easier to clean, especially induction models |
| Safety | Risks of gas leaks or open flame | Safer (no open flame, automatic shut-off) |
| Maintenance | May require professional installation and occasional maintenance | Easier installation, low maintenance |
| Upfront Cost | Lower upfront cost (unless new gas connection is needed) | Generally higher upfront cost, especially for induction hobs |
How to Use an Electric Hob
To use an electric hob effectively, follow these steps and tips to ensure safe, efficient, and precise cooking:
Step-by-Step Guide to Using an Electric Hob
1. Prepare the Surface:
Ensure the electric hob is clean and dry before use. This helps avoid any smoking or burning from food residues and ensures the heating elements work properly.
2. Choose Proper Cookware:
For ceramic or glass hobs, use flat-bottomed pans for optimal heat contact.
For induction hobs, ensure you are using magnetic cookware (e.g., cast iron, certain stainless steel pans). Non-magnetic materials won’t work on induction hobs.
3. Position Your Pan:
Place the pan directly over the selected burner. For even heat distribution, ensure the pan is centered on the cooking zone.
4. Turn On the Hob and Set Heat Level:
For traditional ceramic hobs, turn the control knob to the desired heat setting (usually a scale from 1–9).
For induction hobs, set the power level using the touch controls or knobs. Most hobs will show a digital readout for precise settings.
Heat Levels:
- High (7-9): Boiling, searing, and quick cooking.
- Medium (4-6): Frying, sautéing, and pan-searing.
- Low (1-3): Simmering, melting, or keeping food warm.
5. Adjusting Temperature:
Electric hobs, particularly ceramic models, can retain heat even after you adjust the settings. Be ready to lower the heat or move the pan off the burner to prevent food from boiling over. Induction hobs are quicker to cool down once the power is reduced.
6. Turn Off the Hob:
Once you're done cooking, turn the control knob to the '0' position or press the power button to turn off the hob.
Safety:
- Hot Surface Indicator: Always check for the hot surface indicator light, which usually stays on (often marked with an 'H' or a red light) until the hob has cooled down to a safe temperature.
- Child Lock: Many modern electric hobs have a child lock function to prevent accidental turning on. Make sure to activate this if you have young children in the home.
Additional Tips and Considerations
Preheating: Allow the hob to heat up for a few minutes before placing your cookware on it. This ensures even cooking and saves time.
- Two-Burner Method: If cooking delicate dishes, such as sauces or eggs, use two burners—one on high to get the pan heated, and then transfer the pan to the lower heat to finish cooking gently.
- Cleaning: Clean any spills immediately after the hob has cooled down. For ceramic or glass surfaces, use a damp cloth or a specialized hob cleaner to prevent stubborn stains. Avoid using abrasive materials that could scratch the surface.
- Temperature Management: Be mindful of residual heat on ceramic hobs. If you're using a pan with a lot of oil or water, switching to a lower heat after reaching the boiling point can prevent overflow or burning.
By following these simple steps and taking proper care of your electric hob, you can ensure safe and efficient cooking every time.
Do I Need Special Pans for an Electric Hob?
No, you don't need special pans for a traditional electric hob. Any flat-bottomed cookware works well. However, for induction hobs, you do need pans made of magnetic materials, such as cast iron or certain stainless steel.
Are All Electric Hobs the Same Size?
No, not all electric hobs are the same size. The most common sizes are 30cm and 60cm, which are ideal for most kitchens. However, there are also other sizes available, such as 70cm, 80cm, and 90cm, to suit larger cooking spaces or more extensive cooking needs. The size you choose depends on your kitchen layout and cooking requirements.
