Induction vs Ceramic Hob Running Costs – Which is Cheaper to Run?

It’s well worth checking out the running costs of induction vs. ceramic hob before you choose a new appliance. We’re already experiencing higher energy bills in the UK, with more to come shortly. There hasn’t been such a huge increase in the cost of home energy for decades.

In 2022 alone, Ofgem anticipates your household energy bills will rise by 54% in the spring and a similar amount in the autumn. By this time next year, your household energy could be double what you pay now.

Choosing a hob based on its running costs is suddenly more of a priority than it ever was. Ceramic and induction hobs look identical on the surface. However, they both use significantly different amounts of electricity.

Induction vs. Ceramic Hob Running Costs

Your appliance’s purchase price doesn’t necessarily indicate how much it might cost to run. Currently, an average ceramic hob costs between £200 and £300.

An induction hob with similar facilities can cost twice as much. Why pay so much more for an induction hob when it doesn’t add to the aesthetic appearance of your kitchen?

Many people might hesitate to invest more than needed in a hob. However, the running costs, both now and in an uncertain future, can make you think twice about which hob to buy.

First of all, we need to look a little deeper into how the two types of hob operate. This should help determine how much they might cost to run over their anticipated lifetime of around fifteen years.

Is an Induction Hob Expensive to Run?

Beneath the ceramic glass, the induction hob has cooking zones made of copper wire. They form part of an electromagnetic circuit that produces energy to heat and cook food.

It achieves this by creating an alternating current through imperceptible, magnetized vibrations. This energy is transferred as heat to a pan with a magnetized base, which cooks the food directly.

The electromagnetic field produces and withdraws heat almost instantly. You’ll only need to wait a second or two for the cooking zone to reach the correct temperature.

When you remove a pan, the magnetised connection is interrupted. The energy source is instantly stopped, leaving the ceramic glass surface comfortably cool to the touch. The induction hob only uses the amount of electricity it needs to activate the hob’s mechanism.

An average induction hob uses an estimated 175 kWh during the year. Before any recent price increase in electricity, this could mean an annual running cost of approximately £34.

Is a Ceramic Hob Expensive to Run?

Underneath the stylish glass cooktop, the ceramic hob has more in common with a regular electric hob than an induction hob.

The burners are usually manufactured from cast iron. They are powered by electricity the entire time you have them switched on.

Cast iron is always slow to heat up and retains residual warmth for several minutes after switching off. The glass will feel dangerously hot if you don’t leave a pan in place to continue cooking ingredients with this surplus heat.

The ceramic hob needs a consistent electricity supply to keep the burners operating.

An average ceramic hob uses at least 230 kWh throughout the year. At pre-2022 energy prices, this could mean annual running costs of around £50.

Why are Induction Hobs Cheaper to Run than Ceramic Hobs

As you can see, induction vs ceramic hob running costs are significantly different. Their energy-efficiency generally depends on how the burners operate. The induction hob’s burners have a flexible quality. They reach temperatures fast and cut heat with immediate effect.

The cooking zones only produce heat when connected to a magnetised pan. There’s also no surplus heat being wasted if a pan is smaller than the burner; this equates to an induction hob having an average energy loss of just 10% to 15%.

In reaching temperature settings, the ceramic hob is the slowest of all hobs, including gas or traditional electric.

A ceramic hob’s burners are also fixed in size, this means if you’re using a small pan, the entire burner still needs to be heated, which results in additional heat being lost around the edges. On average, the ceramic hob wastes at least 30% to 35% of its energy.

Conclusion

Induction vs ceramic hob running costs are going to affect your household energy bills in the future. Whether you save or spend more money in the long term depends on the hob you choose and the type of hob you are replacing.

The ceramic hob is the greediest compared to any hob when heating the burners. By comparison, the induction hob starts cooking food when a pan is in place. It doesn’t have any residual heat to waste, either.

The cost of your future household energy bills is unpredictable. An energy-efficient induction hob with low running costs could help lessen the impact.
