1. What are the difference between induction cooktop and electric cooktop?

Electric cooktop features heating element. Electric current is passed through heating element creating heat to cook food. Nevertheless, the disadvantage of electric cooktop lies in loss of energy. Particularly, heat created has been emitted outside before going to heat food.

Differently, an induction cooktop does not create heat on its own. It operates based on the principle of electromagnetic induction. Electric current is passed through coil installed inside the cooktop and then magnetic field is created on the user interface of the cooktop. When users put cookware made of ferromagnetic material on the user interface, there is Foucault electric current on the surface of bottom of cookware and heat is created to make food get done.

2. Does induction cooktop cause any harm to human health?

There are many concerns about magnetic field generated by induction cooktop. Many questions have been raised concerning to influence of induction cooktop on people with heart disease. As stated in many scientific materials, the cooktop creates electromagnetic waves with low frequency. Its frequency ranges from 20 Kz to 23 Kz (far lesser than microwave with the frequency of 2,4 GHz created by micro oven) radiation emitted is considered very little. Therefore, the negative effect of it on human health is insignificant. Indeed, when compared to other cooktops, induction cooktop is considered much safer and more energy efficient because it does not emit heat into environment and it operates without releasing CO, CO2, and burning O2. It is so clean because its surface is made of glass- ceramic material, which can be cleaned easily. It does not create heat by itself so the surface of the cooktop cool down quickly. If users touch surface of the cooktop accidentally, they won’t get burnt

3. Is induction cooktop used only for making hotpot?

This is wrong opinion. You can cook various dishes with using induction cooktop. The cooktop is indeed technological superior to other cooktops with different cooking modes. Specially, some modern and expensive cooktops are designed to cook automatically. Users just select type of cooking, adjust temperature accordingly and then the cooktop will be switched off when the food gets done. Thanks to this advanced technology, users can do other household tasks during cooking meal without much worry about that food might get burnt.

4. Is induction cooktop hard to use?

Absolutely not. Although it is considered as advanced technology, it is not complicated for users to use the cooktop. In fact, the cooktop features functional buttons. You just touch the buttons to choose different setting based on your requirements. More conveniently, the cooktop is set with some cooking modes for you to select accordingly. As mentioned before, some modern cooktops feature automatic cooking program so it will be switched off by its self when it gets done

5. Should users choose reputed brand induction cooktop?

It is totally depend on users. Many people are persuaded by cheap induction cooktop but you will get what you pays for. Normally, the cheap one cannot guarantee users long time of using and good quality. Furthermore, it does not come with some advanced functions. High standard induction cooktop benefits you advanced setting, long time using guarantee, elegant appearance which will make it an ornament in your kitchen.

6. Does electricity cost increase when using with induction cooktop?

Many people might concern electric bill at the end of month when they use induction cooktop. They assume that the cooktop with high capacity will consume much more electricity when compared to other electrical appliances. They are all wrong. We have to consider time-saving factor because the cooktop have high capacity. Furthermore, to induction cooktop, heat is created on the surface of cookware’s bottom and has no chance to be realized into environment. As a result, it is far more energy efficient, less energy loss when compared to other traditional cooktops.

7. Does radiation of induction cooktop have negative influence on human health?

Because induction cooktop generates electromagnetism, many people raise the concern about harmful effects which it might have on people. Technical experts stated that there were no harmful effects on human health but there has been no official experiment to prove it. Don’t worry. All specifications and scientific materials show very little influence on human health, even on people with heart disease.

8. Is food magnetized when they are cooked with induction cooktop?

Electromagnetic field which is created by cooktop cannot affect in wide scope. Electromagnetic field exists only on the surface of cooktop as well as a couple of millimeter away from the surface of cooktop. Therefore, there is no way in which radiation from cooktop has influence on food or human. Technical expert affirmed that food cannot be exposed to radioactive or toxic substance.

9. Can I use any types of cookware with induction cooktop?

Only cookware made of ferromagnetic material can be compatible to induction cooktop. Normally, cookware suppliers can suggest the reliable cooktop if needed. In case users use cookware which is made of non- ferromagnetic material, it does not interact with cooktop. Even it might interact with the cooktop, small amount of heat is created in cookware forcing cooktop to run at higher power. As a result, cooktop is destroyed or gets burnt. Thanks to advanced technology, iron plates are commercially available to help non-ferromagnetic cookware interact with cooktop.

However, it is strongly suggested that user not apply this way for such reasons as low efficiency, unsafety and high risk of explosion..

10. Is cooking with induction cooktop different from that with other cooktops?

The answer is absolutely no. Although the principle of induction cooktop is far different from other cooktops, cooking experience with all types of cookware is the same. Basically, all cooktop use heat to help your food be done. That distinguishes induction cooktop from other cooktops is the power, various cooking mode setting accordingly. What you need to focus on is tips to use it effectively.

For example, setting suitable mode is considered to ensure the quality and nutrient of food. As affirmed by manufacturers, different levels of temperature are designed to save time and make cooking more convenient. More importantly, users should note that power of the cooktop is relatively high. Users might not get familiar to the fact that is possible to cook food in very short time. Therefore, it is recommended that new users pay high attention to cooking time, inspect all cooking mode by themselves. And then it is much easier for them to distribute time for preparing food and cooking smartly.

11. Is that my kitchen perfect for induction cooktop?

In fact, induction cooktop is considered safe and suitable to most of kitchen. However, if your kitchen is not spacious enough, you need to consult the opinion of technical supporter. In case your kitchen is too small, some objects can be magnetized and break. Under some circumstances, it is suggested not to use best induction cooktop in your kitchen. You also are recommended whether your electricity capacity in your house can support induction cooktop or not.

12. Does the user interface of cooktop crack?

Under some circumstances, the surface of cooktop cracks after couple of months. But don’t worry. This situation is right for only low quality cooktop. In case of high quality cooktop manufactured by reputed brand, this situation never happens. User interface of high quality cookware is made of high quality glass which features high duration, high thermal resistance. Two reputed manufacturers who specialize in user interface are Schott and EuroKera.

In addition, scratch faced usually by users. The problem lies in the fact that users using sharp object while cleaning cooktop. In order to use cooktop for longer time, user should use soft cloth, specialized spray for cleaning. Do not leave any piece of food at the bottom of cooktop because it can block the heat conduction process.

13. Does loudly sound from cooktop show some problems of induction cooktop?

There are many possible reasons for this problem. Firstly, loudly sound comes from fan installed into the cooktop. As far as you concerned, high capacity of induction cooktop requires cooling system. Fan runs the whole cooking time and continues to run when the cooktop is switched off. However, if you buy expensive cooktop imported from Euro, you will never experience this case because the fan run without making annoying noise.

Secondly, the problem lies in the electricity providing for cooktop. When user change different cooking modes, power required changes accordingly. The sudden change can cause constant noise like that. Thirdly, loudly noise might results from the interaction of cooktop with cookware. In case the bottom of cooktop is rough, power creation process is not effective forcing the cooktop to operate at higher capacity. As a result, loudly sound happens
