Comparison Smeg KLF04WHEU white vs Smeg KLF03WHEU white

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.

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.

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.

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.

A small mesh (usually at the spout) that catches scale flakes and small particles to prevent them from getting into the cup when pouring. Its convenience lies in the fact that the filter can be quickly removed, rinsed under the tap, or cleaned with a soft brush without taking the kettle apart and without fussing with citric acid every time just for a few "crumbs" in the drink. Unlike non-removable inserts or "for show" filters, the removable option is easier to keep tidy, clogs less, and stays neat for longer, especially if the water is hard and the kettle is actively used at home or in the office. In practice, this is useful when you frequently boil water for tea/coffee or children's drinks: the filter does not completely solve the scale problem inside, but it significantly enhances comfort because there is less residue in the cup and the taste remains cleaner.

Boiling sound signal — a convenient feature that notifies the user when the water heating is completed. It is usually implemented as a short beep or melody after the appliance automatically turns off.
