Induction cookers, consumption: how much does an induction hob consume? What are the energy costs associated with its use and is it worth it? All the info.
How induction cooking works
Induction hobs exploit the electromagnetic currents generated by the coils placed under the surface of the hob. Thanks to the electromagnetic field it is possible to heat only the pot and not the hob which remains cold.
To generate the magnetic field, the coils need metal pans such as steel and cast iron; an aluminum or ceramic pot, would not go to start thehobbecause they are unable to activate the electromagnetic field. To overcome this problem, there are on the marketcookware for induction cookersmade of ceramic, aluminum and terracotta that enclose a metal layer (iron or steel) on the bottom so as to allow the coils of induction hob to activate the electromagnetic field.
Induction cookers, consumption
We come to the sore point of induction cookers, consumption. Betweenpros and consof ainduction hobconsumption weighs heavily on the balance sheetversus.
In energy terms, oneinduction cooker consumesless than a kitchen with a classic gas stove but the consumer has the fact that methane costs much less than electricity.
Theinduction cookersthey are electric and oblige the consumer to enter into an ad hoc contract with the energy supplier. This means it would be *almostimpossible to meet the energy needs of a house and power oneinduction cookerwith a 3.3 kw contract.
Who wants to buy ainduction hobmust *almost surelyincrease the capacity of the meter to 4.5 kW or even 6 kW.
By increasing the output capacity, the price per kW also goes up: the energy manager has a very clear pricing policy per kW, the more it consumes, the more the price per kW increases.
**I say almost impossiblebecause many manufacturers are launching theinduction cooktopshigh efficiency which see absorption peaks of 2.4 - 2.6 kW. Absorption peaks occur only when the entire hob is used at 100%, this means that theinduction cookerin question could work with the normal 3.3 kW contract taking the necessary precautions. In any case, even to those who choose to limit the power of oneinduction cookerat “only” 2.4 kW it will be convenient to increase the electricity contract to 4.5 kW.
N.B. in some well-known blogs we read that the energy bill with a 4.5 kW contract and an induction hob limited to 2.4 kW would not exceed 120 euros per two months even using washing machines, dryers and all that a family of three or even 4 members uses around the house. This statement is very dubious and I would advise you not to take it as a reference. For an effective economic reference, make a simple estimate by calculating the costs by multiplying the hours of use of the appliance (calculated over the course of the month) by the kW absorbed. Then multiply the total kW by the price of your operator's electricity. Add the costs obtained to the ordinary price of your electricity bill. Only in this way will you be able to understand how much they will weigh on your electricity bill iconsumptiongenerated by ainduction hob.
How much does an induction cooker consume?
As stated, ainduction hob consumesless than a conventional gas cooker, this is because theinduction cookingdelivers heat exclusively to the bottom of the pot. In this way, the pot will take less time to heat up, the induction hobit produces energy only to overheat the pot: the other surfaces remain cold. The energy expenditure is minimal and, compared to a normal gas hob, for the same energy used (2 kW), an induction hob offers an efficiency greater than 90%.
Another factor that affects theconsumption of an induction cookerare the cooking times. In ainduction hob, all the thermal efforts are concentrated on the metal pot, this greatly reduces cooking times.
For example, induction cooking times are reduced to 3 minutes to bring a liter of water to a boil while a gas hob takes 5.
To lower the running costs of ainduction hobit is necessary to carefully read the energy label of the product at the time of purchase. Choose oneinduction cookerthat has absorption peaks compatible with your electricity meter and with the rest of theconsumptionof the House. To further lower the costs related toconsumptionenergetic, the ideal would be to use theinduction hobto make the most of the electricity produced by a domestic photovoltaic system.
