Design

The design in which the electric kettle is decorated. In addition to the classic design, nowadays there are more original styles, namely:

Retro. Devices stylized antique — mainly for kitchen utensils of the 30s — 50s of the XX century. The degree of stylization in this case can be different: for example, some appliances are not different from ordinary kitchen kettles that are placed on the stove. Also note that almost all samovars are performed in retro style (see "Type"). But thermopots and teapots in this design are almost never produced. Anyway, a retro kettle will be indispensable for a kitchen in the same style, but it can also fit into a modern interior.

Hi-tech. The devices that have a technological, sometimes even futuristic design — using unpainted metal, transparent glass, as well as a minimal amount (or even complete absence) of decorative details. At the same time, the design can be quite unusual: for example, there are models that taper upward and vaguely resemble laboratory flasks. Like the retro style, almost no other devices are produced in this style other than classic kettles.

When choosing a device in a specific design, note that the design inevitably affects the cost — sometimes quite noticeably, despite the fact that it usually does not provide functional advantages.

Water level indicator

A device that allows you to estimate the amount of water in the kettle without opening its lid. Most often the water level indicator has the form of a scale applied either to the transparent wall of the container, or to a transparent insert in an opaque wall. In any case, this function allows you to measure the volume of filled water quite accurately, and not just determine it “by eye”. This possibility is especially important for models with open coils (see "Heating element"), in such devices, a mark on the indicator is usually applied to the minimum allowable water level.

Thermostat

A device that allows you to set the temperature to which the water will be heated — the thermostat monitors the temperature and automatically turns off the heating when the desired value is reached. In fact, water heated in a kettle does not always need to be boiled: for example, for brewing some types of tea, the optimum temperature is about 80 °C, and for preparing baby food — 60 °C. Thermopot are most often equipped with a thermostat, but there are also classic electric kettles with such a function.

Temperature adjustment

The temperature adjustment capabilities refer to the specific temperature values that can be programmed into the electric kettle. It's important to note that this refers to automatic adjustment, where the kettle turns off or switches to temperature maintenance mode once the desired temperature has been reached.

If this paragraph contains several options separated by commas (for example, “60 °С, 80 °С, 90 °С”), this means that this model has several fixed temperature options. However, there are also devices with smooth adjustment, which allows you to adjust the temperature in steps of 5 °C, or even 1 °C; for such devices, the entire adjustment range is indicated here, for example, "60 — 100 °C".

The greater the number of temperature setting options available in an electric kettle, the more versatile it becomes, allowing for precise selection of the optimal brewing mode for various types of drinks. Here is a simple table of recommended temperatures:

white tea — 60 °C;
yellow tea -70 °C;
green tea — 80 °C;
black tea — 90 °C;
— rooibos, hibiscus — 100 °C (up to boiling);
baby food — 40 °C.

Of course, there are exceptions to such rules — depending on the specific type of drink. For example, some...varieties of green tea can be brewed at 90 °C.

Maintaining t° (kettle)

The ability to operate a classic kettle (see "Type") in the mode of maintaining the water temperature — when the heated water is kept hot due to the operation of the heater at low power. For kettles, unlike thermopots, this mode is far from necessary, so its presence is indicated separately in the specs.

Thermometer

A device that displays the temperature of the water in the kettle. The presence of a thermometer is useful if the water needs to be heated to a certain temperature. However, the thermometer does not automatically turn off the kettle, unlike a thermostat — this must be done manually. Also, the thermometer allows you to assess how much the heated water has cooled over time and whether it can be used without heating again.

Removable lid

The ability to completely remove the lid of the kettle. Such a possibility is not of particular importance during regular use, however, it provides additional convenience if the kettle needs to be washed from the inside — a removable lid, unlike a traditional non-removable one, will not hang on the fixture, hit your hands and create other discomforts. On the other hand, there is a certain risk of losing this lid, so this feature is not common.

Body shape

The general shape of the body of the electric kettle.

Conical. The most popular option: a body is wide at the base and tapering upwards. This form contributes to stability: the centre of gravity is maximally displaced downwards. However washing such a kettle from the inside may not be very convenient due to the relatively small size of the opening in the upper part.

Cylindrical. The cylindrical shape provides more or less the same width of the body at the base and at the top. With the same height and base diameter, such kettles hold slightly more water than conical ones; in addition, such a device is easier to clean due to the wide opening for the lid.

Inclined. The body which is inclined forward; the width of such a body is usually more or less the same over the entire height. Such kettles have an unusual, eye-catching appearance; in addition, it is easier to pour water from them — the device must be inclined at a smaller angle than with a cylindrical and even with a conical body. However, this option does not provide fundamental advantages over the same cylindrical shape, but it is more expensive, and therefore is not common.

Double-walled

Double-walled are found mainly among traditional electric kettles.

This design performs several functions at once. First of all, it significantly improves thermal insulation, allowing the kettle to retain heat longer and save energy when heating. Also, double-walled increase strength and reliability — it is more difficult to break through such a wall or noticeably damage it than a single one. And in some models, the outer side is made of plastic, and the inner side is made — of metal; this allows you to combine the advantages of both materials without a significant increase in cost.
