Basically, kettles have a long tradition. In Japan, this tradition is still lived today, especially when it comes to preparing green tea. Cast-iron kettles are mainly used, which give the tea an additional aroma. In Japan, they are affectionately called tetsubin.

Because a cast-iron water kettle releases components when preparing tea, these are said to add to the flavour of the tea. However, because the aroma is less desirable in coffee, these induction kettles are less popular for making coffee. There are different types of induction kettles made of different materials. Find out which one is suitable for which hot drink in this article.


  • Kettles are available in different designs. Be it in colour, shape or material. But the materials have their advantages and disadvantages and some are less suitable for induction.
  • When buying, you should pay attention to the different materials as well as the capacity. In order for your new induction kettle to work on your induction cooker, it should also be suitable.
  • This is particularly important for induction kettles made of glass, copper or aluminium. This is especially important for induction kettles made of glass, copper or aluminium, because these in particular have a ferromagnetic material in the base.

Induction Kettle: Buying and evaluation criteria

So that you know what to look for when buying an induction kettle, we have listed some criteria here:

In the following, we will go into more detail about the criteria and explain them to you in more detail.

Filling quantity

The filling quantity is one of the most important features of an induction kettle. It determines how much water can be boiled at once. Induction kettles are available with a volume of one to three litres. If you use the kettle less often, a volume of two cups is usually sufficient.

Before buying a kettle, you should consider how many people you will be boiling water for on average. If it is only for a single household, a capacity of one litre is sufficient. If it is a multi-person household or a large family, a three-litre induction kettle can be advantageous.


Since induction kettles are essentially the same in terms of functionality, the design is often the most important criterion. Induction kettles come in different colours, shapes and materials. It is therefore important to pay attention to good workmanship, which promises good quality.

Induction kettles are available in colours ranging from anthracite to red to black, with or without a wooden handle.

They are made of stainless steel, enamel, cast iron or glass and are therefore plastic-free. Therefore, water kettles for induction are tasteless and particularly suitable for boiling water.


A kettle for induction can have various additional functions. The following functions may be available:

  • Level indicator
  • Thermometer
  • with flute / whistle

An induction kettle usually only has a thermometer if it does not have a flute. However, a flute has the advantage that you are informed by an acoustic signal that the boiling point of the water has been reached. A level indicator is usually placed on the outside instead of inside. This makes it somewhat awkward for most consumers to fill the appropriate amount.

Cooker types

With regard to the types of cooker, it is particularly important to ensure that the kettle for induction is also suitable for induction cooker plates. This is because certain materials are equipped with a ferromagnetic base. In most cases, it is also possible to cook on other types of hob. Such as on:

  • Electric cooker
  • Gas cooker
  • Open fire

Few kettles for induction cover all possibilities, especially that cooking can also be done on an open fire. The advantage is that the same kettle can even be used for outdoor activities.

Guide: Frequently asked questions about induction kettles answered in detail

In the following section, we answer the most frequently asked questions about induction kettles. This will give you a deeper insight into the topic and the most frequently asked questions will be answered for you.

Who is a kettle for induction suitable for?

Basically, an induction kettle is suitable for all those who have an induction cooker at home. However, induction kettles made of glass, copper or aluminium require a base that has ferromagnetic properties. As they are usually somewhat more expensive, it is only worth buying an induction kettle if the kitchen is also equipped with a suitable cooker. It is also possible to use induction kettles on other types of cooker and even over an open fire.

An induction-compatible kettle has two main advantages over a kettle. Firstly, induction kettles have a larger base, which heats the water more quickly. Secondly, it has a larger capacity. Compared to a kettle, this is usually 1.5 litres. With an induction kettle, this can go up to 3 litres.

What types of induction kettles are there?

In general, there are different materials that kettles are made of. Each has its own advantages and disadvantages. They are listed in the following table:

Type Advantages Disadvantages
Stainless steel tasteless, easy to clean, for all types of cookers, good heat conduction properties, large selection brands usually high-priced
Glass tasteless, easy to clean, filling quantity always visible not shatterproof, only suitable with, ferromagnetic metal base
Enamel good heat conduction, robust, easy to clean, for all types of cookers, very light weight Heating takes a little longer, gets dents easily, enamel layer must always be intact, relatively high price if completely enamelled
Cast iron excellent heat conduction properties, very robust, very suitable for tea high price, less suitable for coffee, high weight, components can come off
Copper looks good, good heat conduction usually high price, components can come off, pure copper is not suitable for induction
Aluminium light, very good conductivity, robust, inexpensive cools down quickly, can dent easily, not suitable for induction

As we can see, every induction kettle has its uses. However, it should be mentioned that copper, glass and aluminium are only conditionally suitable for induction. The prerequisite for these is that they have a ferromagnetic metal base.

What does an induction kettle cost?

Listed below are different price ranges of induction kettles. The price ranges from a few euros to the more expensive ones from 50 euros.

Price range available products
Low-priced (10 - 30€) mostly induction water kettles made of stainless steel with no additional functions except a flute.
Medium-priced (30 - 50€) available in different materials with displays and more special designs.
High-priced (50€ and above) high-quality, different materials with appealing designs.

Depending on the workmanship, kettles for induction become more expensive. Inexpensive ones are available for as little as 10 euros, but the quality of the workmanship suffers as a result. If you are looking for a durable and robust induction kettle, 30 euros will go a long way.

How does an induction kettle work?

An induction hob generates eddy currents, which are transmitted ferromagnetically in connection with the base of an induction kettle. Inside the kettle, these currents continue to swirl and heat the water further, just as with a gas or electric hob.

Since direct heat transfer takes place in an induction-compatible kettle, the water reaches the boiling point even faster due to the eddy currents with the low heat loss.

When the boiling point is reached, the water evaporates through the attached flute. When the water vapour escapes, an acoustic signal is emitted, indicating that the water is now hot enough for coffee or tea.

But beware. Not every material is naturally suitable for an induction cooker. Kettles for induction made of aluminium, copper or glass require a base that transmits the ferromagnetic waves. Since these materials are non-magnetic metals, an additional base is required that is made of a magnetic metal. These are usually iron, nickel, cobalt or alloys.


An induction kettle has several advantages. One is the large capacity. Compared to a kettle that only has 1.0 to 1.7 litres, an induction kettle has a volume of up to 3 litres. In addition, the water is heated quickly due to the eddy currents generated and the good insulation of most induction kettles.

This is further supported by the good conductivity of the materials and a tightly closed system. In addition, tea, coffee, milk or other drinks can be heated in an induction kettle. Since no heating elements are integrated, it is also easier to clean in the sink than a kettle. Some models can also be washed in the dishwasher.
