What power is the electric kettle in kW

Power of household electrical appliances.

And this means that for such a power, the electric cable must be at least 4 mm by cross.Section (see the table of the cable and the stressed loads in the KW) and, accordingly, the direct cable eyeliner to the meter and through the machine for 25 amperes (loads on electric machines, table on the page Eletro security).

Provided that we are talking about electricity single.Phase, that is, 220 volts.

For independent calculation of the cross.Section of an electric wire, you can familiarize yourself with the approximate consumption of electricity by power, certain home electrical appliances.

Why do you need to know this: for those who decided to independently make an electrician with their own hands in their country house; “Not professional electricians” that they had not done things; professionals in their business, which would be remembered that he was not to save on the wire and electric machines; and just curious people to get acquainted.

The entire principle of the safety of electrical loads and t. D. It boils down to: calculate the power consumption in the room 7 kW for example (devices, equipment), select an electric cable that holds 7 kW of load (at least holds. ), and install electrical machines, which should be disconnected when an load is exceeded 6 kW, better than 5 kW.

How in Soviet SNiPs it was correctly double or even triple margin of safety. Better, as they say. Do your own electrician, mount the wires and sockets, but calculations on loads and resistances, it is better to pay professional electricians to make a project.

You can also independently on our website in the online calculator calculate the power consumption of kW/hour by various household appliances (refrigerator, microwave, washing machine, electric kettle, microwave, electric stove, electric grill, toster, electric iron, drying machine, blastol. Home air conditioning, computer, TV).

The main characteristics of electric teapots

Ancestor of a modern electric kettle. Boiler.

The heating tube touched into an intricate spiral was hung on the edge of a glass, pots or buckets and was included in the outlet. The flowing electric current was heated by the spiral and with it the liquid. Then the designers occurred to the idea of ​​cutting the boiler into the wall of the water container. This is how the electric kettle appeared.

The history of electric dummies began with such a boiler

The first electric kettle was shown at the 1893 World Exhibition in Chicago. The device was designed by the English inventor Samuel Crompton, who mounted an electric heating element into a metal teapot stand. In 1923, Arthur Lardge proposed placing the heater in the water.

Over the past years, the kettle took the main place on the kitchen table, models appeared that differ in size, power and purpose. Let us dwell on the main characteristics.

Type of heating element

By the type of heating element of the factory, two types of teapots are produced: with open and closed spirals.

  • Water must necessarily close the element to the top, so as not to burn out. Do not boil one cup in such a kettle.
  • A scale is formed around the spiral from above and below, which is difficult to remove. Because of this, the water is warming longer, the taste worsens.
  • No fuse against water boiling. If the heater works “dry”, it will be redeemed and burned out.

Open heating element: boiling water is cut into the kettle case

  • The scale in the teapot is easier to remove.
  • Even one cup of water is warming on the flat bottom.
  • The circuit breaker is triggered after boiling water.
  • The fuse does not allow to turn on an empty kettle.

The closed heater is hidden under the lid, not visible and does not interfere

In the latest generation teapots, a heating disk is used, combining the advantages of open and closed elements. There is no spiral in the disk, the electric current is brought directly to the disk contacts. Such a kettle heats up better and less noisy.

Power consumption

220-3000 watts are presented on store shelves of stores. When choosing the power of the device, the general approach is this: the more powerful the device is, the faster the water will boil. And this is played by marketers, promoting more powerful (and more expensive) devices.

Keep in mind that with an increase in power, the current force flowing through the wires increases. For a teapot with a heater from 1,500 watts, we recommend using copper wires, with a cross section of at least 0.5 kV. Mm, and for 3000 watts. At least 1.5 kV. Mm. The given table will help evaluate the boiling time of 0.5 liters of water for heaters of different power.

Table: Water boiling time depending on the power of the heater

Heater power (W) Current strength (a) Boiling time (min)
600 2.7 6:00
1300 5.9 2:50
1900 8.6 1:30
2400 10.9 1:25
3000 13.6 1:10

As can be seen from the table, with a power increase from 2500 to 3000 W (watts), boiling time does not increase much, and the current grows significantly. For a volume of 1.5-2 liters, we recommend choosing a kettle with a heater power 1700-2200 W.


How to find out the power of the kettle

Responsible manufacturers write capacity on the bottom of the device. The text of the stamp on plastic or placed on a special sticker. In our case, the power of the Braun 3221 kettle is indicated on the label, the range is 1.9-2.2 kW/h.

TOBR TOBE: Giants and dwarfs

In stores, both tiny teapons are sold for a couple of mugs with a volume of 0.5 liters, and giants, boiling water boiling up to 5 liters of water in one reception. The average flask size is 2 liters.

The volume of the teapot is selected by the need of the owner. We recommend evaluate how much water you consume for one meal. If tea is drinking a married couple, enough and a liter flask. But if a family of five people enjoys coffee in the morning, the child is brewed with a milk mixture, and dogs are poured with dry food, then a heater is required at least 2-2.5 liters.

Which body material is better: metal, plastic, ceramics or glass (comparative table)

To compensate for the disadvantages of materials, manufacturers combine metal and plastic, metal and glass, plastic and glass.

Additional functions

In an effort to increase the attractiveness of goods, manufacturers add new functions to them. For example, Tefal has created a KO 410 Thermovision kettle (I see the temperature), which shows the temperature using the backlight. The glow of the lamp smoothly changes from blue to red, and the exact temperature of the water shows a digital indicator on the handle.

The stores sell the Tefal Ki 410 Thermovision Inox teapot model in the steel case.

Electrician case

One of the key characteristics of such a technique is the material used in its manufacture. Now the devices of 4 varieties are produced:


Such teapots are most widely used. Of the advantages, financial availability, durability, small weight, variety of colors can be highlighted. Cons. The possibility of the presence of an unpleasant odor, low strength, a fairly quick fading of the external design.


Pros. Shock resistance, long service life. Minus. A high degree of heating of the material during the operation of the device can cause a burn if it is inattention.

When buying, you need to make Accent on the device handle. It should be comfortable for her. A stainless steel teapot is made with two surface options. Glossy and matte. The first variety looks spectacular, but needs careful care, the second is easy to maintain, there are practically no fingerprints left on it.


This modification allows the user to observe the process of boiling water. For its manufacture, special heat.Resistant glass is used. Pros of glass electric kettle. Unusual and environmental friendliness. Separate models boast of the funeral. Cons. Fragility, the need for careful care, noisiness of work and a high level of heating.


A similar category appeared on the market relatively recently. It is made of certain varieties of clay. Of the advantages, a presentable appearance, the uniqueness of design solutions, simplicity of care, noiselessness, safety, the possibility of long.Term maintenance of temperature should be noted. In addition, in most models a set of cups is attached. The disadvantages include excessive fragility, high cost, high weight, slow water heating.

Each type of electrician has its strengths and weaknesses. This should be taken into account when selecting a particular model.

The power of the electric kettle

Before purchasing a kettle, you must in advance on the power of this technique. It is necessary to focus on ensuring that it is optimal for the conditions in which the equipment will be operated. It is very important to do this, since the wiring of old houses while turning on several powerful devices may simply not withstand the load.

The characteristics of almost all modern models indicate a capacity of 600 to 3000 watts. This indicator is directly proportional to the volume of the kettle. The larger the size, the higher the power. For the home, models with an indicator of 1500 watts are most often purchased. They can boil 1.5-2 liters of water without problems. It takes 2 to 4 minutes to the whole process. Thanks to these characteristics, these dummies are very popular.

Electrician Braun WK 5110 with a capacity of 3 kW

If you need a device for rapid heating of a larger water volume, it is recommended to purchase more powerful ketters with an indicator of 3000 watts. They are able to perform the boiling process in two minutes, so they are in demand among the owners of institutions where they sell hot tea and coffee.

It is important to remember that especially powerful types of equipment are able to seriously load even the newest wiring, especially when a washing machine or air conditioner works with them at the same time.

All this leads to the fact that the electrician overheats and is much faster. And its replacement will cost a large amount. In addition, during overloads on the network, automatic protection is triggered. And this can have a negative impact on any electrical engineering in the house.

How to find a phase in a socket, and why three.Phase are needed; how to measure the voltage and determine the current strength

Often, when making any changes to the electrical wiring, it becomes necessary to determine the phase wire. Regardless of the voltage in the outlet, according to modern standards, they should have color marking. So the yellow-green wire is grounding, and blue or blue is zero. Accordingly, the rest (one or three). Phase, usually phase wires are:

However, in some networks mounted until 2011, the black wire was used to ground. In addition, it is customary to connect the phase on the right in single.Phase wiring.

If there is no marking, then a sample with a neon lamp will come in handy. When touching the phase, the indicator will light up. If a sample with an LED is used, you can not touch the metal platform at the end of the handle when checking. To determine which current in the outlet, a voltmeter is needed. It will also come in handy when determining the phases of a three.Phase connection. So between each of the phases and zol will be 220V at a linear voltage of 380V and 127V. With a 220V linear (but the last connector is practically not found and is not used). In domestic networks, a three.Phase connection can be used for kitchen furnaces with high.Power electrics. Terminal shields in some models allow, thus, evenly distribute the load.

The amount of energy consumed

Electric kettle. One of the household appliances that most actively consume electricity. As a rule, the indicator of the power consumed by him is from one and a half to three kilowatts per hour.

For example, with five.Time use of the device during the day, with three.Minute heating or boiling water per month, it will consume about 18 kW. In comparison with other household appliances, this indicator initially does not seem so high. However, here it is worth considering that most devices can consume approximately the same volume of electricity, working around the clock, unlike the teapot used for such a short time.

What the power of the electric kettle depends on what

Modern models come on sale with different power indicators, but when choosing it is important to consider future operation. The amount of energy consumed depends on:

  • Volume of the flask. The larger it is, the amount of electricity consumed higher;
  • Type of heating element. Modern models on sale come with open or closed heaters. If the former contribute to a faster heating with lower electricity consumption, then the latter heat the water longer, respectively, the electricity consumption will be greater;
  • Water quality. Running water that has not passed filtration contributes to a faster formation of scale. As a result of this electricity, more than one heating cycle is consumed.

Each modern teapot has a different power, but its value never exceeds 700-3000 W. These indicators are enough for use for domestic purposes. Nevertheless, models with a capacity of 1,500 watts are considered optimal. Such teapots in one cycle can bring two liters of water to a boil, which is enough for a family of 3-4 people.

When faced with the choice of electric kettle, pay attention not only to the design, but also the characteristics: volume, power, type of heating element and others. This will allow you to buy small household appliances that will perform the necessary functions, while consuming a minimum amount of electricity.

Technical characteristics: what to pay attention to

Such a huge number of models of domestic and foreign brands are presented on the shelves of stores that it is just right to be confused. For many buyers, the main criterion for choosing is an attractive design, but we must not forget about the technical parameters. It depends on them how much you will pay for electricity (in total with other units working from the network).

power, electric, kettle
  • The power of the teapot. Each model has its own indicators. From 600 to 3000 watts. When choosing, it is precisely this parameter that is paid attention in the first place, especially if the device works in houses of the old building. When included in the network, worn wiring may not withstand. But in the new high.Rise buildings, too powerful models give a serious load, and when you include several units (washing, boiler, air conditioner, microwave), automatic protection is triggered and traffic jams are knocked out;
  • Little of the device of the device. Teapots with a volume of 0.5-3 liters are produced, and here the consumer himself decides which model will do. For a family of 3-4 people, 1.5-2-liter capacity is enough, “babies” with a volume of 0.5 liters are useful on a trip or to those who live alone;
  • Type of heating elements. Common inexpensive devices with a spiral (heater) of the open type boil water faster, discs closed work more slowly. The minus of the first is that over time the heater is covered with a raid, the water boils longer, energy consumption above. Devices with a spiral closed do not have such problems, but they are more expensive, they consume more electricity and, judging by the reviews, they make no more noise.

The case material plays a role. Metal models heat up and cool faster. Ceramic and glass teapots work slowly, and after that they retain the water hot.

Kettle and its functionality

Which is still better-a compact kettle or innovative thermopot? The answer depends on your goals and the specifics of the devices.

Types of electric teapots

Electricians are small household appliances with a removable or built.In tank, in the lower part of which there is a heating element. The container is filled with water. On the housing there are control buttons (powering/off), power cord, thermostat.

Devices are available in the following variations:

  • Plastic. Inexpensive and durable. Models have a container of various transparency;
  • Glass. Environmentally friendly and safe teapots, can be equipped with backlight;
  • Metal. Made of stainless steel, characterized by strength and reliability;
  • Ceramic. When heated by water, they practically do not make noise, but have increased fragility.

Advantages and disadvantages of electric kettle

Teapots are suitable for quick cooking connoisseurs of hot drinks. Among the advantages of devices:

  • Universality. It is used for boiling water, cooking hot drinks, sometimes for cooking eggs;
