Induction hob: how it works, how much it consumes and how to best use it

For some it is the kitchen of the futurethe ecological turning point that will allow us to bring our dishes to the table without using methane gas and consuming as little energy as possible: let’s talk about the induction hoba revolutionary and increasingly popular cooking system. Powered by electricitythe induction hob does not require the use of methane gas: therefore no flame but only heat given off by a magnetic field. Aesthetically appealing and energetically (almost always) sustainable: induction is a cooking method that allows you to locate the heat eliminating the possibility of waste And reducing considerably the preparation times. What is it and how does it work? How do you use the induction hob? How many kw do you need for an induction hob? What are the advantages of induction plates? Let’s get to know the induction hob better, between advantages and possible weaknesses.

Induction hob: how it works

Comprehend the mechanism of the induction hob it can also explain the reasons for its increasing success. The operation of the induction hob it’s very simple: unlike the “traditional” hob, the induction hob does not use gas, but it is powered byelectric energy. The surface of the induction hob is a “simple” glass resin plate under which some are placed coilsrest on a ferrite core: the coils heat up through the electrical energy e create a magnetic field, this field will directly heat the pot or pan (and obviously their contents); all of this without generating any flame and above all without producing no heat loss.


And the yield? The induction hob does not generate heat dispersion or leaks presents a very high yield: all the heat produced in fact ends up directly in the pan and therefore in the cooking of food.

Question temperature: how to regulate it? All the latest generation induction hobs allow you to adjust and set the temperature very precisely: in fact, through a simple display, it is possible to choose the most suitable level of heat for the recipe, in each of its preparation phases.

Advantages and disadvantages of the induction hob

After including operation of the induction hob, we can analyze in more detail i advantages and disadvantages of this cooking systemin the differences that exist with the more classic gas-powered one.

Between benefitswe can undoubtedly point out:

  • Yield: the induction cooker does not produce heat loss and therefore it is “zero waste”. This means it can achieve a yield equal to 90%against the estimated 40 – 60% of a methane gas cooker.
  • Speed: if all the heat produced is used, it is easy to guess that cooking times will significantly decreasein some cases up to halving.
  • Cleaning: forget encrustations or clogged nozzles, clean the hob is child’s playall you need is a cotton cloth and a stain remover and degreaser.
  • Safety: induction is a highly safe hob because that’s not all it does not involve the use of flames but also because the heat is “localized” only on the part of the surface on which we rest the pots, all of it the remaining surface remains cold.
  • Aesthetics: in the kitchen the eye always wants its part, not only to present our recipes in the best possible way. The induction hob presents an aesthetically appealing designespecially if inserted inside a modern kitchen.
  • Ethics: if powered with electricity produced from renewable sources, the induction hob is not only cheaper but also more eco-sustainable.


Being to what was discovered, the induction hob would seem to be the perfect solution to all our problems but even in this case it is good to be careful. The induction hob also presents some disadvantagesamong which:

  • Initial expenditure: if you intend to buy an induction hob, it is good that you know that theinitial investment I will be lightly greater compared to a more common gas cooker.
  • The right tools: to use an induction hob it is necessary use pots and pans with special magnetic properties (made of cast iron, special stainless steel or enamelled steel) and with a flat bottom. Changing the hob will therefore mean buying new, special tools.

Use the induction hob allows us to save? To fully answer this question, we must consider multiple factors. An induction hob generates a fairly high current draw, especially when used at maximum power it can reach a consumption higher than 3 kW, average capacity threshold of the meter, which is therefore advisable to increase. However, it must be accompanied by consumption the time of use which, as we have seen, is significantly lower than a gas cooker: for this reason, net of the different tariffs and costs of the different energy sources, it is possible to say that an induction hob is more “economical” than others.
