One of the first electric kettles appeared in the late 19th - early 20th century. Over time, their design, improved functionality.
Now the range of electrical devices is so great that the modern buyer difficult to pick up a desired option. Below is a brief overview of electrical products, their positive and negative characteristics.

Characteristics dummies with a thermoregulator
What is different from the conventional electric kettles the same, but with built-in thermostat?
A fundamental feature of the dummies with thermostat is a thermostat control software.
Such models can accurately set the temperature of the heating fluid on the LCD screen.
The presence of the regulator maintains the desired temperature are periodically inserted after the cooling water.
The main components that distinguish the thermo-electric kettles are:
- The thermometer is equipped with a sensor
- A memory unit with stored workflows
- Control panel for display modes
- The electronic board
This instrument will be useful purchase for fans of a variety of beverages. On the control panel there are options:
- 40 ° - for the preparation of infant formula;
- 60 ° - infuser white teas;
- 70 ° - 85 ° - green teas, red (not fermented);
- 85 ° - 95 ° - flower, yellow leaf teas are not fermented;
- 95 ° - 100 ° - red tea, fried, leafy oolong, fermented Puer herbal teas.
Resource to heat the liquid to the desired temperature has the advantage of electric kettle thermostat.
Autotemperature starts heating the fluid to a desired temperature during cooling.
On the other hand, it is a disadvantage of the kettle with temperature control, because the power consumption increases due to the periodical inclusions, and it is not always necessary.
The main characteristics that are worth paying attention when buying:
- types of thermostats
- Capacity
- Power
- housing material
- Heating element
- Security
- Filter
- unwound cord
- Lock-off switch when the cover is open, without water
- Illumination at work
Temperature regulators Electrical products come in two forms: stepless or stepped. By means of stepless regulators may continuously expose the heating fluid temperature to within tenths of degrees.
Stepped controls allow to adjust the temperature only in certain values, in increments of about 10 degrees.
It is necessary to determine the control: some manufacturing temperature control button arranged on a special support, while the other on the housing.
Capacity
By volume kettles are distinguished:
- Small - up to 1.5 liters
- Medium - most common -1.5 - 2.5 liters
- Large - 2.5 - and more.
Choose should suit your needs and the number of people who can simultaneously use the unit. The greater the capacity, the more expensive the product.
For a family of 3-5 people or for the office, you need to choose a product capacity of about 2-liters, and for a family of two people sufficient and 1.2 liters. The most common models have a volume of 1.7 liters.
Power electric kettles are divided into:
- 1500 W
- 1500 W - 2500 W
- 2500 W
The water in the kettle heats up quickly, you should choose a more powerful model.
For 1.2-liter kettle acceptable 1.5-2 kW power, but the 2-liter types desirable to select a capacity of at least 2.5 kW.
If the wiring condition is not good enough, you should choose a brand with less power. Optimum power 2-2,2 kW. Time boiling liquid depends on the shape of the goods. The wider the bottom of the device, the water boils faster.
Types of dummies with thermostat
plastic
Plastic or iron body can leave unpleasant water. glass product does not contain formaldehyde or nickel, so foreign taste the water will not.
Electrical plastic made of polypropylene and polycarbonate. Polypropylene is denoted by two Latin letters PP, it has a sharp smell peculiar, strong heating when water dissolves a noxious substance - formaldehydes.
Polycarbonate is designated by letters OTHER, more durable high quality plastic has a less pronounced flavor.
Plastic cheaper the price, and are the most common. Plastic is durable enough, but eventually loses its appearance.
metal
On environmental grounds metal durable plastic. Iron electric kettles durable than their counterparts, as are long-lasting and preserves the appearance. The metal pattern is not necessary to leave the water at night, the metal is oxidized, and the oxidation products (iron oxide) will fall into drinking water.
It is better to choose a product of stainless steel, aluminum without impurities that do not fall into the water harmful substances.
Stainless steel is very durable material, so break iron appliance harder than made of plastic. Now the range of home appliances is a whole range of products of different types.
There combined varieties: a metal block is coated with plastic, whereby it obtains the advantages of plastic products.
Metal Kettles intense heat, it causes a danger to children. Negative quality of metal kettles - they are more expensive than plastic. Filled with water from the kettle metal may weigh up to three kilograms.
The metallic product is sometimes absent scale water level. Availability scale apparatus leads to the risk of leakage. Metal prototypes noisier operation.
glass
Glass eco-friendly material. But you should pay attention to the details of the glass product. They are made of plastic and metal. Plastic or metal parts must conform to acceptable standards.
(The plastic should be made of polycarbonate, and stainless steel metal.)
Better to choose a product from a thicker glass. This product is boiled water taste better than in the other.
By weight glass and metal products heavier than plastic.
On the strength of the most solid materials is an iron kettle. If you miss out on a glass or plastic instrument, it may crack.
heating elements
- closed TEN
- outdoor heater
- Spiral (open)
Such a parameter as fire protection depends on the type of heating element. boiling time varies depending on the housing materials. The metal product liquid is heated more quickly than in a kettle made of glass or plastic. And if you open the heating element, the liquid begins to boil any time soon.
With closed Tenom
Last for a longer time, since the heating element is isolated from the water - is integrated into the bottom housing.
At the time of heating the water affects the volume of the cup, the size of the heating element, its power.
With an open Tan
Outdoor heater Representing a spiral located at the bottom of the kettle. The lack of devices with open-helix - the fragility, the low level of security. Spiral quickly covered with scale, which is almost impossible to clean. In addition, a wash kettle difficult.
To electric is not ignited, it should pour a minimum amount of liquid (200 grams). Should focus on the minimum amount of fluid indicated by the mark on the scale of MIN letters.
Water filters are removable and built. First it lets it be easily removed for cleaning of the scum.
Exploitation
Plastic pots is recommended to use no more than 2 years. The metal is not more than 5 years. Glass to 10 years of operation. Otherwise, after the expiry of said period, even in the kettle body of higher grade materials, water will enter the harmful substances.
It is important that when choosing a brand called attention to the quality of the cable. It must be sufficiently strong, heavy, thick. Must exist on the cable marking, which specifies the cross section of the cable, and a manufacturer performance.
Cord Length in most models is 0.6-1.3 meters. Short and long equally uncomfortable, so it is better to buy products with a wire average. Conveniently, if the cord retracts into the base.
If the cover is open in the kettle, there is no liquid, the device should not be included (a useful feature off without water).
It is a significant component of lights. It is usually on the LEDs. It indicates the presence of power, or the start of heating (in various models in different ways).
It happens that the color of light changes depending on the mode, it's very convenient. It is also possible to meet with the prototype backlight gradually receiving a different color-matched with the fluid temperature. It turns out that the color varies gradually as they approach the boiling point.
Disadvantages Dummies with thermostat
The larger components in the device, the more functions it has, the greater the chance of breakage.
Increased consumption of electricity (not to be left on the device, if you are not going to use it in the near future or the unit will heat wasted)
The high cost of species with the function of thermoregulation
It increases the probability of failure of temperature control, so over time the thermostat can fail: cease to maintain the desired temperature
How to choose
With proper selection and judicious use, an electric model with temperature controls will save significant energy consumption.
Must be purchased models of products with thermostats only reliable, branded stores.
For low-quality models typically: a long time boiling, foul odor inside the device, which appears during heating, due to use of cheaper substandard materials used for the manufacture of housing.
To an electrical appliance is not fast out of order, it is necessary to use good-quality models. The decision to buy a kettle with temperature control should be taken in the event that you require constant availability of hot, boiled water.
