Induction hobs: how they work and what pans to use
Induction hobs have become a staple for our clients to elevate their new kitchens. Thanks to their simplicity and sleek design, they improve kitchen functionality and help to create a clean space. With more people ditching gas-powered cooking to reduce their carbon footprint, induction hobs offer a more sustainable and energy-efficient solution compared to gas hobs.
Keep reading to learn more about induction hobs, including how they work, what pans to use, and what things to consider before you install one into your home.
WHAT IS AN INDUCTION HOB?
Similar in appearance to an electric hob, an induction hob is a sleek glass cooktop that usually sits flush with your countertop. Underneath the glass surface are copper coils. Induction cooking uses electromagnetic energy to create an alternating magnetic field, which induces electric currents in the metal of the pan. These currents generate heat directly in the pan itself. When a suitable magnetic pan is placed on the glass surface, the electromagnetic field is activated and heats the pan. Once the pan is removed, the electromagnetic connection is broken, and the hob stops generating heat.
There are many extractor options for induction hobs. The traditional overhead extractors can be used, however many new hobs, from brands like BORA, are fitted with a downdraft extractor. This extractor is fitted within the hob itself and effectively extracts steam, smoke and grease from the atmosphere through its filter.
WHAT PANS WORK ON INDUCTION HOBS?
Induction hobs require cookware that is compatible with their electromagnetic heating mechanism. This means that your pots and pans must have a magnetic base to work with induction cooking. Cast iron, stainless steel (with a magnetic base), and carbon steel are commonly used for induction cooking. Additionally, some aluminium and copper pans are compatible if they have a magnetic layer added to the bottom. Look out for the induction-compliant symbol on the bottom of your pan or packaging to ensure its compatibility.
To check if your existing cookware is compatible, place a magnet on the bottom of the pan. If it sticks firmly, the pan is suitable for an induction hob.
ARE THEY ENERGY EFFICIENT?
Induction cookers are considered to be one of the most energy-efficient cooking appliances. Unlike gas or traditional electric cooktops, which heat indirectly, induction hobs heat the cookware directly through electromagnetic induction, minimizing heat and energy loss. Since the heat is generated directly in the pan, there is significantly less energy wasted as residual heat.
Moreover, many induction hobs come with safety features that automatically turn off the hob if no pan is detected or if the pan is removed, further preventing energy waste.
Things to consider
Although there are lots of benefits to an induction hob, there are a few things to consider before you buy.
The main point is the price; A new induction hob should be considered an investment. While prices can vary, a good quality induction hob can start from £1,000 plus installation costs. Choosing a high-quality appliance might seem like a pricey option, however, the longevity of the product will minimise the need to replace it which will benefit you in the long run. Another thing to consider is if your existing pans are not compatible with induction cooking, you’ll need to buy new magnetic pans, which can be costly.
Additionally, the hob surface is made from glass which can be prone to scratches. Scratches and marks can be prevented by carefully placing pans onto the surface instead of scraping and dragging. To clean up food spills, use a soft damp cloth instead of anything scratchy and abrasive which might cause marks.
Induction cookers cause pots and pans to heat rapidly, while this is great for energy efficiency and reducing overall cooking time, the increase in speed and heat intensity can take some getting used.
While these points are important factors to consider, we recommend induction hobs to our clients. Not only do they look sleek and sophisticated, but their energy efficiency makes them one of the most sustainable options.
