This is interesting: the first electric kettles were introduced at the end of the twentieth century. In the process of evolution, electrothermoses, thermopots appeared, and finally in Israel in 1994 a device was presented with a stand and autonomous shutdown after boiling water.
Principle of operation
Regardless of the level of design complexity, all electric kettles are equipped with special heating elements and a thermostat. After the device is installed on a special delivery, by pressing a button connected to the electric kettle, the current passes through the above parts. As a result, the heat carrier is heated. The maximum temperature in this case can be 100 C, but due to impurities in tap water, the maximum threshold, as a rule, is from 93 to 95 C. The optimal temperature is determined by the thermostat, which is responsible for automatic shutdown of electricity. Modern models can be additionally equipped with a mode of maintaining a given temperature. In this case, after cooling the water, the device turns on autonomously.
Types of Electric Kettles
To make the right choice of an electric kettle, you should know about what types of devices are there at all. Currently, there are 3 types of electric kettles:
- ordinary - differ in a simple design with an open heating element;
- express kettles are more functional, durable and faster analogues. The main parts are made of stainless steel. In such devices, almost no scale is formed;
- Thermal sweat - allow you to additionally store heat inside the tank. It is worth saying that water heating takes longer, since such inventions have a low power (800-1000 W). But there is a pump, thanks to which the water is supplied offline.
If you plan to allocate a small budget for the purchase of an electric kettle, focus on solutions with an open heating element. Thermal sweats are great for people aged. For intensive use, the express kettle is the best choice!
main parameters
If you don’t know which electric kettle to buy, consider 5 key characteristics: the type of heating element, performance, filtration quality, material of the casing and the power cord. We will try to find out which parameters are optimal:
Performance
Of course, the higher the power of the device, the kettle will boil water more efficiently. But the “flip side of the coin” is high energy consumption. The optimal parameter for a teapot with a volume of up to two liters is a power of 2200 watts. As a rule, thermal perspiration have a lower value.
Choice of housing
If you do not know which electric kettle is better to choose, carefully consider the quality of the case. It is important that there are no gaps, defects, crevices. In this case, the features of different materials should be considered. For example, plastic electric kettles are cheaper, but they are short-lived. Glass analogues are environmentally friendly, but prone to breakage. Metal and steel cases are not afraid of mechanical damage, but are much more expensive. The best choice is a ceramic teapot that is easy to clean, has an optimal price and works quietly.
Filter
In most cases, electric kettles are equipped with replaceable filters. For budget models, they are made of nylon mesh. When it comes to choosing a premium electric kettle, focus on gold-plated or metal filters, as they are more durable and better, often do not leave scale.
Heating element selection
Currently, manufacturers offer three versions of the heater: disk, open, closed spiral. The first option involves the location of the heater inside the device. Attracts affordable cost, but difficult to operate. An open spiral leaves a coating that is difficult to clean. It is important that the element is completely in the water. The hidden spiral is more often used in thermal sweat. Located under the metal disk. It is easier to clean, even a cup of water can be heated. Cost is 10-15% higher. Disc heaters are the most expensive, but suggest maximum efficiency and lack of scale.
Additional features
If you do not know which electric kettle to choose for your home, it will be useful for you to find out about the existing options:
long boiling mode - allows you to completely remove chlorine from the coolant;
- timer - you can adjust the heating of the coolant to a specific time;
- a sound signal is a useful option that will not allow you to forget about preparing hot water;
- temperature regulator - allows you to set the required heating temperature;
- protection against overheating - an option that blocks the inclusion of an electric kettle if there is no water in it;
- maintaining optimal temperature is a useful mode of operation for saving electrical energy.
Naturally, the presence of additional options is reflected in the price of the device.
How much is a good electric kettle?
To choose the right electric kettle, it is worth considering the price-quality ratio of the product. When buying a ceramic kettle with a closed type of heating elements and the above functions, count on the amount from 5000 to 7000 rubles. De'Longhi offers good solutions in this price range. Devices with a full functional set will cost 10-12 thousand rubles. The best premium manufacturers are Tefal and Bosch. We deliberately do not talk about budget devices, since it is more advisable to buy one good kettle than several cheap ones!
