Power consumption
The power consumed by the kettle during operation is actually the power of the heating element installed in the device.
Two working moments depend on this parameter: heating intensity and electricity consumption. On the one hand, the
high power of the heater allows you to quickly heat up a certain volume of water and saves time. On the other hand, the power consumption of such a device will also be appropriate. The wattage of a kettle's heater typically does not have a significant impact on electricity bills since the energy consumption required to heat a given volume of water remains the same regardless of the heater's power rating. However, there may be certain issues related to electrical connectivity. For example, if the wiring is weak or the fuses are improperly sized, the operation of a high-power heater may cause power outages. Additionally, devices with a power rating greater than 3500 W cannot be connected to a regular electrical outlet and require a specific power format. Consequently, even the largest thermal pots, which typically have a capacity of 10 L or more, are rarely equipped with heaters more powerful than 3000 W, since this power rating is sufficient for their intended use and can be connected to a standard electrical outlet.
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.
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.
Opening the lid with a button
Kettles (see "Type") in which the lid opens at the touch of a button. This opening is faster and more convenient, and often safer than the traditional way (grab the lid and pull it up): the lid can get quite hot when the kettle is in operation, and long contact with it is fraught with burns. And although the button can also be placed on the lid, a short press is enough to activate it, and even in such cases the risk of getting burned is minimal. On the other hand,
opening the lid with a button complicates the design of the kettle and reduces its reliability.
Control via smartphone
The ability to remotely
control the kettle from a smartphone, tablet or other similar gadget with a special application installed. The connection can be made via Wi-Fi or Bluetooth.
This feature does not only allow you to control the device from a distance, but often gives you more options than the classic control method. For example, special "chips" like a timer or thermostat can only be accessed through the application. In addition, the information about the operation of the kettle is transmitted to the application — for example, thermometer data, status (on/off), etc. Due to plenty of features, models controlled from a smartphone are often called
“smart kettles”. Their main disadvantage is their high cost.
Controller
The name of the controller installed in the device.
The controller is called an electronic circuit, which is directly responsible for managing the operation — primarily for turning off the heating when boiling or turning on without water. In our catalog, the name of such a circuit is specified if we are talking about an advanced controller that significantly exceeds most solutions on the market in terms of quality and reliability. At the same time, the specs indicate not a specific model, but a general brand — this is quite enough in this case.
The most reliable, durable and safe nowadays are the controllers of the British manufacturers Strix and Otter. There are no fundamental differences between these options in this regard, any of them is a sign of a quality kettle (even if the overall functionality of the device is rather modest). On the other hand, such equipment affects the price.
