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.
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.
