Kitchen Hob Buyer Guide | Types of Hobs Explained
Hobs are an essential part of any kitchen. They’re the focal point of our culinary endeavours and, without them, we’d be unable to cook many of our favourite meals.
However, there are different types of kitchen hobs – and it’s important to understand the unique benefits and limitations of each before choosing which type is best for you.
What is an Induction Hob?
An induction hob uses electromagnetic fields to generate heat within the cookware.
It relies on induction technology to transfer heat, making it energy-efficient, quick-to-heat and precise. The surface of the kitchen hob also remains cool during cooking, making it the safest option in a busy household.
How Do Induction Hobs Work?
Induction hobs use electromagnetic fields to create an alternating current in the hob’s coil beneath its ceramic surface.
This current induces a magnetic field in the cookware, generating heat directly within your pots and pans.
The hob itself remains cool and heat is only generated when compatible cookware is present.
Advantages of Induction Hobs
The key advantages of induction hobs include:
- Rapid heating.
- Precise temperature control.
- Energy efficiency.
- Safety with a cooled surface.
- Easy cleaning.
Limitations of Induction Hobs
The limitations of induction hobs include:
- Requires a specialist set of induction cookware with magnetic properties.
- Higher initial cost.
- Potential noise disruption from cooling fans.
- Needs a dedicated power supply.
Can potentially produce electromagnetic interference that can affect nearby technology.
What Is a Gas Hob?
Gas hobs are what most of us picture when we think of kitchen hobs. It’s a type of cooktop that uses natural gas to generate heat.
They use Bunsen burners with adjustable flames to create a desired level of heat beneath the pan.
How Gas Hobs Work
Gas hobs work by distributing natural gas through pipes to the burners located on the kitchen hob.
When that gas is ignited, it creates a flame that heats your pots and pans.
The flame intensity can be adjusted with a dial to control the temperature of the hob.
Advantages of Gas Hobs
The advantages of using gas hobs include:
- Precise temperature control.
- Quick heating times.
- Even heat distribution.
- Compatibility with a wide range of cookware.
Limitations of Gas Hobs
Gas hobs also have a few limitations that are worth considering before choosing a kitchen cooktop:
- Higher energy consumption (making them more costly to run).
- Potential for open flame accidents and fires.
Harder to clean than other types of kitchen hobs.
What Is an Electric Hob?
An electric hob – as its name suggests - uses electricity as its power source instead of gas. It typically consists of heating elements that are embedded beneath a solid plate or ceramic surface.
Electric hobs provide consistent heat distribution and offer different heating elements for a variety of cooking requirements.
These elements include but are not limited to – radiant, halogen and coil.
How Electric Hobs Work
Electric hobs work by using an electrical current beneath a glass or ceramic plate to generate heat across the plate's surface.
When the hob is turned on, the heating elements warm up – this transfers heat to the cookware placed on the hob.
Advantages of Electric Hobs
Some of the advantages of electric hobs include:
- Precise temperature control.
- Easy-to-clean surfaces.
- Compatibility with various cookware.
- No open flames for improved safety.
Limitations of Electric Hobs
However, some of the limitations of electric hobs include:
- Longer heating time.
- Increasing or decreasing temperature takes slightly longer.
- High energy consumption.
Choosing the Right Kitchen Hob
Choosing the right kitchen hob can be tricky. There's a lot to keep in mind when selecting a hob for your kitchen, from your cooking habits to how much you’re able to spend.
The main factors to consider include:
- Budget
- Cooking habits
- Safety considerations
What’s Your Budget?
There are kitchen hobs for every budget – from larger models for bigger homes to compact or energy-saving models that cost less to run.
If you’re happy to spend more upfront, an induction hob can provide quick and efficient cooking, while also saving on energy costs long-term compared with gas hobs.
However, electric or gas hobs come at a lower price point and can still be affordable to run for smaller households.
Lifestyle and Cooking Habits
Your cooking habits will likely determine which type of hob is right for you. If you like to cook up a storm in the kitchen, a gas hob provides temperature control accuracy to help you perfect your meals.
However, if you prefer to cook relatively simple meals, an electric or induction hob will get the job done while proving easier to use.
Safety Considerations
For families with children, or in smaller, enclosed kitchens, induction hobs are the safest solution.
They generate no heat on the cooking top itself, reducing the risk of burns or surrounding items catching fire.
Electric hobs also prove safer than gas hobs, as they don’t generate an open flame – however, no hob itself is necessarily dangerous when used carefully.
Ceramic vs Induction Hobs
Ceramic hobs use electric coils under the hob surface. On contact, these heating elements transfer energy to the bottom of a pan.
This is different to induction hobs, which use magnetics to heat the pan directly. With ceramic hobs, the plate surface also heats up – but with induction hobs, only the pan is heated.
Induction hobs heat faster and are more efficient but require special magnetised cookware to use. Ceramic hobs are slower to heat and less energy efficient but can be used with multiple types of cookware.
Which Pans Are Best for Which Kitchen Hobs?
Different kitchen hobs transfer heat in different ways and, therefore, may require unique cookware. So, which hob is best suited to your current cooking equipment?
Below is a simple guide on which types of pans are best suited for each kitchen hob:
Which Pans Are Best for Electric and Gas Hobs?
For electric hobs, pans with smooth, flat bottoms are best – providing as much contact between the pan and the heating element as possible.
For gas hobs, pans with thicker bottoms and even heat distribution are ideal. This is because open flames are naturally uneven, so a pan with a thicker bottom will help evenly spread the heat for the best cooking results.
Do Induction Hobs Need Special Pans?
Induction hobs require specialised pans with magnetic properties made from cast iron or stainless steel. Induction cooking uses magnetic fields to generate heat directly in the pan, so the cookware must have a magnetic base for effective heat transfer.
Do Ceramic Hobs Need Special Pans?
While ceramic hobs don’t require special pans, like electric hobs, they work best alongside pans with a wide base and smooth surface for even contact with heating elements.
Pans with rough or uneven surfaces can also scratch the ceramic plates.
Maintenance and Care for Kitchen Hobs
It’s important to look after kitchen hobs to avoid wear over time, which can affect cooking performance or simply prove unhygienic.
Most hobs can be maintained with household cleaning items and should be wiped down after each use, with regular deep cleaning around every six months.
How To Clean Kitchen Hobs
For gas-powered kitchen hobs, it's important to use a non-abrasive cleaner and a soft cloth to wipe away spills and stains.
First, remove the burner cap and cooking grates. Clean these separately by soaking them in warm, soapy water and scrubbing gently before re-assembling.
Regularly wipe down the cooktop surface and the associated dials with a simple mild detergent solution.
For electric and gas hobs, simply use the same non-abrasive cleaner to wipe down the flat surface of the cooktop.
Remember: It’s important to double-check that an electric hob has been turned off and has been given sufficient time to cool before cleaning.
Gas Hob Maintenance
Regular maintenance for gas hobs includes cleaning burner caps, grates and burner ports and checking gas lines for leaks.
It’s also recommended to schedule provisional maintenance with a qualified gas professional to ensure optimal performance and safety.
Caring for Electric and Induction Hobs
Caring for electric hobs means cleaning the cooktop surface with a non-abrasive cleaner, checking for faulty heating controls and replacing them, and ensuring proper ventilation.
It’s also important to follow manufacturer guidelines and avoid using harsh chemicals that could damage the cooktop.
