How much does an induction cooktop affect your bill? It is very difficult to show with an exact equation how the use of induction cooking is reflected in the cost of the bill, because the way the appliance is used together with the tariff set in the electricity supply contract determine different costs. However, some suppliers offer offers and contracts that can save you up to 25% on your bill compared to conventional gas stoves.
The induction hob is one of the ideal energy-saving solutions: the estimated efficiency of 90% is definitely higher than that of gas hobs, which range between 45% and 65% due to the significant heat dissipation.
In addition to the fixed costs that apply in situations where it is necessary to increase the power on the electricity meter, there are attractive savings options with induction hobs: the gas connection is one of the costs that burden the bill and can even be eliminated.
How much does an induction hob consume and the impact on the bill
Which is better, gas or induction? To see how much an induction hob affects your bill, you can find a practical example. Assuming that you need 450 kWh of heat per year for the hob and neglecting some factors affecting costs, including the way of use, compare these two situations:
- a gas stove with 50% efficiency must use 900 kWh to distribute this heat, which is equivalent to 84 Smc (standard per cubic meter);
- an induction hob with a certified efficiency of 90% consumes 500 kWh per year in this situation.
Considering the price of electricity for single-rate F0 tariffs set at 0.15791 EUR/kWh in the last quarter of 2023, the hypothetical average monthly cost would be equal to 78.96 EUR. Depending on how the prices of the standard per cubic meter and electricity move, in some months you could have a better bill result if you have an induction hob. Even better, the system with Heat pump or photovoltaic panel can eliminate the fixed cost of the gas connection, which is a fixed cost.
How much does an induction hob use per hour?
Induction hobs have improved the performance of hobs always based on electric operation but powered by resistance. In fact, speaking of induction or electric hobs and consumption, in addition to recalling the different functioning of the former compared to the latter, it can be said that the average consumption of induction hobs is between 170 and 180 Wh/kg, fluctuating in the range of 180 – 199 Wh/kg for electric hobs with resistances.
Induction hob: advantages and disadvantages
When we talk about induction hobs, they are no longer new to the industry; in fact, the use of these devices in the kitchen is increasingly common in Italian kitchens. There are several of them benefits offered by the induction hob:
- Speed: the hob’s cooking zones reach the temperature set on the display much faster than traditional gas hobs;
- safety: there is no flame dispersion and the only heated part is the one in contact with the pan;
- surface cleaning: glass-ceramic plate measuring 30 to 90 cm is easy to clean with a sponge;
- reduced energy consumption: high efficiency and absence of heat dissipation have an impact on the bill;
- limited impact on the environment: possible integration with photovoltaic systems represents how power from renewable sources is the basis of induction hobs.
Rather than talking about the disadvantages of an induction cooktop, it is more correct to talk about the precautions that you should not overlook when you want to buy one of these devices. Starting with the most trivial problem pots ad hoc, batteries that can easily be used on induction cookers are now common on the market, as well as adapter discs useful for starting the magnetic field. The basic requirement for these pans is a linear, iron bottom (often labeled induction compatible).
THE installation costs they are undoubtedly very high considering the price difference compared to gas hobs. Despite this, the advantage can be had in the long run, when you can get an idea of the high efficiency of the induction appliance by looking at the bill.
Is 3 kW enough for an induction hob?
One of the critical points of induction hobs is just that absorbed power: in fact, for the operation of these induction panels at the same time as other appliances in the house is the total power 6 kWwhich does not belong to all meters.
THE 3 kW offered by the basic household supply contract may not be sufficient. Don’t panic! Induction hobs also offer a solution to this problem:
- consumption management: allows you to reduce the consumption of the hob by 2 to 1.5 kW and control the hob while other appliances in the house, such as a hairdryer or washing machine, are in operation. When these power limiters are activated, the cooking zones will naturally offer a lower heat intensity;
- increasing the performance of the meter: after analyzing the own consumption and the use of each of the household appliances, the most appropriate solution may be to change the contracted power up to 4.5 kW (for large families) or 6 kW (the maximum available, affecting large families members who often use appliances).
You can request access to this power boost delivered by the meter by contacting your supplier.
How much can you save with an induction hob? A short comparison
Once it is clear how much an induction hob affects the bill, it is important to reiterate what one of its ultimate purposes is. reduction of emissions of greenhouse gases, in addition to the primary objectiveelectrification energy consumption. For example, to obtain thermal energy equal to 1000 W in a pan to be heated:
- The gas cooker must employ 2,000 W;
- The electric hob reaches up to 2,200 W;
- The induction hob uses 1100W with around 90% efficiency.
By comparing different household appliances with the same function, we understand the importance of reducing energy dissipation and the efficiency of electromagnetic induction plates.
