Electricity consumption by the boiler. Rated power of electric stoves and a common equipment device. How many cooking induction panel consumes

Induction plates gradually conquer the popularity of housewives due to their economy. Is it really? Let's try to figure out whether the induction plate is really economical and as a power of consumption induction plate affects electricity bills.

How the induction stove and the principle of its work is arranged

The induction cooking plate consists of a housing, temperature sensor, control panel and power part.

Controls the process of control panel. It is she who determines, put the dishes on it or not.

By the way, not every dishes are suitable for such a device: I need dishes with high ferromagnetic properties, that is, metal dishes with magnetization ability. As a rule, dishes for induction are specially marked with the word "induction" in the translation "induction" or a zigzag icon. But if the manufacturer is not neurons, and there is no labeling, you just need to bring the Magnet to the bottom of the dishes: if it is adherent, everything is in order, the dishes are suitable.

There is also an adapter for induction plates - it allows you to prepare food in aluminum, ceramic and glassware.

The device's technical passport states that the size of the dishes should not be twice as smaller than the burner, otherwise the electromagnetic waves may affect everything that is nearby - electrical devices or people.

The thickness of the bottom of the dishes for the induction plate should be at least 2 mm

The principle of the device is radically different from the device of classical electric stove.

The plate on the principle of the transformer is running - an induction coil is located under the panel of glass ceramics as the primary winding, and the flow of inductive energy is passed. Its frequency is about 20-60 kHz. The dishes are performed as the secondary transformer winding, which is put on the surface. Thus, a high-frequency electromagnetic field is created, which produces heat and transmits its dishes and its contents. The objects are located next to the cooking surface, as well as the hardware itself, are not heated.

Algorithm Action Induction Plate

Induction panels may differ in the following parameters:

in its performance;
in the number of contours;
by the presence or absence of a brass cabinet;
by the magnitude of the hob;
according to the presence of a heating temperature control system.

Power of electricity consumption by induction cooking panels: How is it determined?

Most induction plates has 4 burners different size: The smallest consumes 1 kvatt, two medium sizes consume 1.5-2 kvatt, and one large consumes 2-3 kvatt. The number of burners can reach up to six. Each circuit heats up and adjustable separately, regardless of others.

Knowing out technical passport The power of the burners, by non-speed counting, you can find out how much electricity consumes the device for 10, 15 or 30 minutes.

All information can be found in the passport

If you exploit the device for all the rules, you can noticeably reduce its power consumption. Manufacturers recommend:

the smallest burners use for cooking coffee, a small portion of porridge or stew vegetables and meat;
the largest outline is designed for a large pan with a borscht or frying pan with fried potatoes;
middle contours suggest cooking, extinguishing and so on in medium-sized dishes;
some models encounter paired burners, they can use oval utensils such as masters;
some devices are equipped with special express burners, which have very high power (1.5-3 kilowatt) and are rapid heating hub.

Induction Panel with Double Corner

Naturally, the more burners and the amount of their performance, the more electricity will consume a device. If the wiring allows, it is better to purchase a plate with 4-6 electrocontunches with good power - it will reduce the cooking time and finding the cook itself.

If the wiring is old and its capabilities do not cause confidence, it is better to choose a device with consumption up to 3.5 kvat. A model with such power can be connected independently, just sticking the plug into the outlet.

If the wiring is modern and does not cause doubt, you can take a model with an energy consumption of up to 10 kvatt, but you can not just stick in a free outlet in a free rosette, not take into account permissible load. In this case, individual wiring is needed for powering the electric stove.

Cannot be used to connect induction plates Extension cords and tees: for safe work It must be enabled in the power supply with the work ground.

Power Testing Stove Induction Type

Comparing the induction hob with the usual electrical, you can come to the conclusion that they have the same power consumption. What is the savings?

We carry out the testing of the power consumption of the induction hob and the classic electric stove. Take two 4-korphic plates in which the power is 3.5 kW. On both surfaces we put two 3-liter containers with two liters of liquid room temperature. Covers do not cover. On the classic electric stove, the water began to boil in half an hour - 3.5 × 30 \u003d 1.05 kvat per hour. On the induction after 6 minutes - 3.5 × 6 \u003d 0.21 kvat per hour.
Next test - induction against microwave. Task - heat the glass of milk to 50 degrees. The microwave stove heated a glass with milk for 40 seconds, the stove is the same amount of milk - in 30 seconds.
The third test consists in the operation time of the burner.

For a quarter of an hour, electricity consumption by induction will be 0.175 kvat per hour, just 0.5 kvat per hour. In the usual electric stove in 15 minutes 0.175 kW per hour, but energy consumption will be 1.93 kW per hour.

Induction electricity costs:

electrocontuits - 4 pieces;
operation two hours a day per month - 0.5 × 1.3 × 4 × 2 × 30 \u003d 156 kvat;
operation 2 hours per day during the year - 0.5 × 1.3 × 4 × 2 × 365 \u003d 1890 kvat;
1890 kW × 5 rubles for 1kvatt \u003d 9450 rubles for a year.

The cost of electricity classic electric stoves:

consumption in one hour - 1.3 kW;
electrocontuits - 4 pieces;
operation two hours a day per month - 1.93 × 1.3 × 4 × 2 × 30 \u003d 602 kvatt;
operation 2 hours per day during the year - 1.93 × 1.3 × 4 × 2 × 365 \u003d 7362 kvat
7362 Kvatt × 5 rubles for 1kvatt \u003d 36810 rubles for a year.

CPD induction plate - the highest

It turns out that compared with the energy efficiency of classical electric stove, induction is more efficient 5 times.

Thus, the answer is found. Savings with the help of this device enclosed in its high efficiency - 90% (due to the absence of temperature heating leakage outside the dishes). By the way, the efficiency of the classical electric stove is 60%, gas - 40%. That is, the thing is, for which period of time is used N-E electricity. What it is less, the smaller the amount of electricity will be spent. Energy savings occurs due to a decrease in the time of use. Also, when removing the dishes from the surface, it instantly turns off, which also allows you to save electrical energy.

For a certain amount of time, the induction will justify the funds embedded in it, not to mention the pleasure of cooking on it.

It is often enough, when purchasing a cooking device, attention drops not only on the design of the cooking panel itself and the electric stove as a whole, but also to power, especially if the model is acquired by the induction plate. This equipment has become popular in lately In many countries, as it has a mass positive Parties And, most importantly, efficiency, ease of operation and similar technical characteristicslike power consumption of the electric furnace per month. Due to the fact that the technique was created by modern technologiesIt can consume a minimum of energy by issuing the maximum result.

The model of the electric stove on which induction burners are installed, have a new way of heating food, which allows you to warm or cook dish in the minimum time. The peculiarity of these household electric stove has a magnetic field, which is supported by high-frequency coils, transmitting to the surface of the dishes induction currentHeating.

The cooking surface of the electric stove, for example,Bosch., has:

Temperature sensor;
Hull;
Control panel;
Power part.

Since the cooking panel affects a certain point or, in other words, not the surface of the dishes installed on it, then everything that surrounds this place remains completely cold. It is very useful for those who have small children or are close to such a problem as burns about the surface of the burners.

Regardless of how much the electricity consumes such a stove, you need to purchase a special dishes.

The dishes are selected, which has elevated magnetic permeability and has a fixed value in the specific resistance. Optimal option There will be dishes made of ferrimagnetic cloth, as it fully meets all the requirements.

Power selection of hob

Modern cooking panels or induction plates in which the oven is additionally installed, the connection is connected within 3-10 kW. The digit directly depends on how many burners are present on the surface, as well as on what they have total performance. Basically, the electric stove 4 burners that possess different size, For the convenience of cooking.

In the standard model, the thickness of the burner of the largest size is approximately 2-3 kilowatt, and 1,5 kW is considered in 2 small average performance. On a small hardware, the power is 1 kW.

It is important to use the burners in accordance with their parameters and recommendations from the manufacturer. To be more accurate, it is forbidden to put a large saucepan on a small circle. All circles heat products independently from each other, which does not affect their performance and what consumption will carry out this equipment. In induction plates there are many advantages, thanks to which they are chosen throughout the world.

These include:

The possibility of rapid heating and cooking;
Multifunctionality;
Lack of opportunity to burn;
Easy operation.
High level of efficiency;
The presence of an automatic switch when removing the dishes;
Lack of dependence of the power consolement relative to the voltage in the network;
Economy in consumption;
Excellent specifications.

Unfortunately, the technique is not deprived of both minuses, but they are not so significant and sometimes they are moving into the background. It is required to select a special dishes. Repair can only hold a master. The stove exudes radiation to other devices installed in the kitchen.

Induction stove: how much electricity will need to work

Some people sometimes are very difficult to change the old good electric stoves with conventional burners to new and high-tech equipment, however, if you consider these models more carefully and familiarize yourself with the principle of work and electricity consumption, then it may be quickly changed.

Basically, does not affect the purchase, then:

How much product weighs;
What is the design;
Is the oven model, or there is an additional connecting part for cooking dishes in a closed space;
How much is the product costs.

First of all, the consumption of electricity energy per hour and, accordingly, the total amount of consumption of this resource is important. It is worth noting that the usual four-door induction cooking panel has a capacity of 3.5 kW. Similar power U. electric stoves With Tanni.

If you compare efficiency, it is necessary to heat 2 liters of water on the plane of the usual type with thesters, it will take 30 minutes, and when using induction, just 5.5 minutes.

You can only make a conclusion that energy consumption in the second case will be 6 times less. Depending on the view of the burner on the induction plate, not only the specific energy consumption is carried out, but also what products are preferably prepared on them. On Konforka little sizeThe capacity that averages 0.4-1 kW is mainly the preparation of dairy cereal, coffee or meat extinguishing. On the largest burners are preparing food in a large tank. Middle burners, coming up for cooking meat dishes, vegetables, porridge and other side dishes for the whole family.

There are rapid heating burners, have the highest connection power, which provides the ability to prepare with them quickly and most deliciously as possible. There are models in which the drift of the dual species, which allows you to put on them to use dishes non-standard sizeFor example, oblong. The total power of connecting induction cooking panels will directly depend on the model, quantity and size of the burners. It is much easier to use slabs, on which at least 4 burners, which allows you to prepare several dishes at once.

Optimal Energy Consumption Induction Plate

Even W. gas stove The hour of work will require a much more resource than when using plates in which the type of induction surface is set. The work of such a product, as already noted, directly depends on how well the high-frequency coils are functioning, an average of 30-60 kHz, due to which the electromagnetic field is created. The peculiarity of such a mechanism of work is to be in reducing the level of energy consumption, which primarily affects the costs of the budget to pay for such a resource.

Behind the cooking process watches a special panel, at the expense of which:

Recognized dishes;
The power of the induction field is adjusted;
The presence of dishes on the surface is monitored and, when it is removed, the device is turned off.

To demonstrate the real power of the induction plate and in order to recognize how much energy is required for the preparation of products, it is enough to carry out a small experiment. It is described above, and this is a banal boiling water. As a basis of cooking, you can take the cooking of dairy porridge or coffee, but in any case, the cooking time will be much lower than if you do it on a standard stove.

Almost all models of induction plates have low energy consumption, which makes these slabs in demand worldwide.

Power consumption induction plate (video)

It is worth noting that when buying needs to be paid not only to power, but also on the quality of the equipment, and it is desirable to give preference to those plates that are created by well-known manufacturers. It will get really quality equipment for cooking food.

Induction cooking panel is another generation of electric stove, the principle of operation of which is based on the use of such a phenomenon as electromagnetic induction. Their ever-increasing popularity contributes comfortable and safe operation. In addition, one of the most important factors is low electricity consumption with enough high power Heaters. Due to this application of modern technologies.

Principle of operation of the induction cooking panel

Kitchen Electric Developers household appliances It was possible to use the phenomenon of electromagnetic induction when creating cooking panels. At the same time, it was necessary to install spiral and tubular heaters (TENOV), which significantly increased the reliability of the electric stove and reduced the number of electricity consumed.

Constructively conversation of induction cooking panel presentsa transformer, the primary winding (induction coil) of which is located under the glass-ceramic top panel. The secondary winding of the transformer serves the dishes that put on the stove from above.

Important! Cookware for cooking on the induction panel should have a massive metal bottom thickness of at least 2 mm, which is made of materials with ferromagnetic properties,

The hob need to have a permanent connection to the power supply network to automatically start working when installing special dishes in the burner zone (and only so). Wherein alternating current, passing through the coil, generates a magnetic field that causes the bottom of the pan in the ferromagnetic material (frying pan) the appearance of high-frequency (30-60 kHz) induction currents, which leads to the heating of the metal to the required temperature. The cooking process is carried out by thermal flows emanating from the heated bottom of the dishes.

Induction heating is characterized by small thermal losses, which contributes to the considerable acceleration of the cooking process. Vividly see how economical use the induction method of heating relative to the gas and electric, can be comparing their coefficients useful action (KPD):

Efficiency of the gas stove,% - 60-65;
Efficiency electric stove,% - 50-60%;
The efficiency of the induction plate,% - 80-90%.

The high efficiency of the induction plate is due to the fact that electricity is not spent on the heating of the glass ceramic panel. Inductive currents heat only dishes.

Power consumption of induction hob

One of the main parameters performance characteristics any electric stove in general, and the induction cooking panel in particular is it electric powerb This value affects not only the power consumption, which directly depends the size of monthly financial spending, but also on the speed of cooking.

Konford

The electrical power of induction cooking panels can reach 10 kW. This value depends on the number of burners and the general performance indicator. In this case, the surfaces of this type, as a rule, are equipped with heating elements Not the same power. They are made of different geometric sizes and are intended for various cooking modes:

little Konforkand with a capacity of 1000 W, used in the mode of slow preparation of products (porridge, meat, etc.);
medium-sized hardwarehaving a capacity of 1500-2500 W is designed for cooking soups and sides;
powerful (up to 3000 W) Konford It is able to heat the dishes to a temperature of 500 ° C, so it is used to prepare food in a large container dish.

Note: In the generally accepted sense of the burner on the worst surfaces of the induction type. For the convenience of use in the glass-ceramic panels draw their contours.

In addition, there are models equipped with double burners. Their presence allows the cooking surface to independently change the heating temperature depending on the size and shape of the installed dishes.

Energy consumption

Electricity consumption when using the induction panel depends on the total number of burners. Wherein, the greater the power of consumption, the more efficient productivityhob. High power consumption allows you to quickly cook food, respectively, reduces electricity consumption.

Tip! By purchasing an induction cooking panel, it is necessary to take into account the state of electrical wiring in the house.

On the domestic market you can find induction panels:

low power, kW - up to 3.5;
average power, kW - from 3.5 to 7.0;
high power, kW - from 7, 0 to 10.0.

Power characteristics conventional and inductive electric stoves are almost the same. At the same time, the latter significantly economically consume electricity, which is explained by their higher productivity.

The main indicator on which the performance of the plate is determined is not the total power of simultaneously included hobs, and how much they consume electricity per unit time (kW / hour per month). It is for this parameter that directly depends on the heating rate of the dishesThe induction panels are superior to the remaining types of electric stoves.

Advantages and disadvantages of induction cooking panels

Induction cooking surfaces, like any other type of household electrical appliances, have their advantages and disadvantages. So, according to experts and user reviews, induction surfaces have such advantages Regarding classic electric stoves:

faster heated food;
have a higher efficiency due to which electricity savings are ensured;
automatically turn on when equipped with dishes and disconnected when removing it;
have more functionality;
more convenient and safer in operation;
exclude the possibility of obtaining a burn, since there is no heating directly by the hob;
independently adapt to the diameter of the bottom of the dishes;
exclude burning food, which greatly simplifies the care of the panel and others.

However, despite the indisputable advantages, induction panels are not deprived disadvantages. The most essential of them:

the impossibility of using dishes made of aluminum and glass;
a small noise that creates a constantly working cooling fan.

Overview of popular induction cooking panels

Currently induction cooking surfaces are issued by all well-known manufacturers. kitchen equipment (Siemens, Electrolux, Whirlpool, etc.). The product range includes not only desktop and embedded cooking panels, but also complete induction plates, the power of which depends on the number of burners. Based on reviews of specialists and consumers, models that are determined Top 5 rating of the most popular induction cooking surfaces.

Conclusion

Induction heating in kitchen electrical stoves and cooking surfaces is today the most advanced technology used for cooking. Equipment that uses such a heating method is distinguished by low power consumption and high reliability, while ensuring a reduction in time for thermal processing of products.

The main reason for the overwhelming desire to buy an induction panel is its not a small price, which is still significantly higher than the cost of electric stove equipped with Tanni. Also stops potential users the need to acquire additionally kitchen utensils with magnetic properties.

By purchasing electric stove, consumers pay attention not only to the functionality of the product, but also how much electricity will be spent during operation. Currently, almost all manufacturers of household appliances have developed special stickers containing information on electricity consumption.

How is power consumption?

Electricity electricity consumption depends on the type of electric stove, classical or induction type. Also on electricity consumption affects the saturation of the slab with features and heating elements.

To calculate the electricity consumption of electric stilt, you need to know the power of the burners and the time allotted for operation.

Classical electric stove with conventional tanks (tubular electric heaters) with a capacity of 2 kW in 15 minutes Consumption from the power supply of energy equal to 2 kW ⋅ 0.25 h \u003d 0.5 kW / h. Considering that the price for 1 kW / h in Russian regions is different, the average will be 4 rubles. It will turn out 0.5 kW / h x 4 r. \u003d 2 R.- The cost of the work of the electric stove in 15 minutes.

By testing and values \u200b\u200bof the passport characteristics, it can be found out how much electricity consumes an induction type electric stove. As an example, an induction stove ENDEVER IP-11 is used. Having a 2 kW with a capacity of 2 kW, for 15 minutes the work plate for consumption of electricity as much as classical. But there is a significant plus, thanks to the absence of leakage of heat flows by the dishes, the efficiency increases to 90%, respectively, the opening time of the plate decreases. Another plus in favor of saving electricity that when removing the dishes from the stove, the cooking surface is automatically shut off.

Testing of electricity consumption by a stove of classic type and induction

Both four-meter plates, with a capacity of 3.5 kW. It is heated with a capacity with 2 liters of water of the pan in the first case, the usual 5 l, without a cover, in the second case, the dishes for induction slabs are also 5 liters, and also without a lid. The initial temperature of the water 21 o C.

Classic stove - Water boiled after half an hour,

3.5 x 30 min / 60 min \u003d 1.75 kW / h.

Induction stove, boiling time amounted to 5.5 min,

3.5 x 5.5 min / 60 min \u003d 0.32 kW / h.

The second measurement will be in the time of the burner.

In 15 minutes, the average electricity consumption of the induction slab will be 0.175 kW / h, the total energy cost is 0.5 kW / h.

In the classic stove for 15 minutes, the same 0.175 kW / h, but energy costs will be 1.93 kW / h,

Induction plates costs.

In a month in 30 days, the amount will be 156 kW x 4 \u003d 624 rubles.

Classic stove.

Per month: 463 kW x 4 \u003d 1852 rub.

The induction stove is an analogue of classic plates with various additional advantages.

The values \u200b\u200bin this calculation can be used, because it is not necessary that the stove will work 2 hours a day, or all 4 burners will be involved, and the cost for 1kW / hour is different in each region.

Electricity consumption by konfords of the classic plate.

For 1 hour of work, the classic electric stove, depending on the position of the power adjustment handles consumes electricity.

The burner with a diameter of 145 mm, 1 kW in the 1st position consumes 0.10 kW, 2 gears. - 0.17 kW, 3 Paul. -0.25 kW, 4 Paul. -0.50 kW, 5 Paul. - 0,75kW, 6 floor -1kW

The burner with a diameter of 180 mm, 1.5 kW in the 1st position consumes 0.14 kW, 2 floors. - 0.22 kW, 3 floors. -0.30 kW, 4 Paul. -0.85 kW, 5 Paul. - 1,2

One of the first is the question of which power should be used by the acquired device. it important factorwhich will help determine how the panel is better to choose - gas, induction or electrical. What depends on the power of the unit and how much it is different modelsRead more.

What determines the power of the hob?

The power of the cooking panel is an important parameter Selecting the device for three main reasons:

The capacity depends on the speed with which your dishes are heat treatment. Agree that it is better when it is possible to prepare dishes as quickly as possible.
Modern plates have burners of different power, and it is very convenient. If you just need not a large number of Heat, why waste excess gas or electricity for useless heating air in the kitchen. However, you should consider and reverse side The question is the power of the greatest burner should also be sufficient to quickly weld a large saucepan of soup.
On the modern kitchensRegarding conditioners are installed. When the heat isolate in too large quantities, the load and the air conditioner increases accordingly. In this case, extra costs and heat heating, and on its cooling is completely not justified.

So, it is worth choosing a cooking panel with such a power so that the cooking time was rapid, but the heat released is optimal.

Electric cooking panel

Electrical appliance traditional design consumes the greatest electrical power Of all the types under consideration, so the review will begin with this option.

The largest distribution on the market in our time received plates with four burners. Thus, the standard number of heating points over the decade of domestic slabs has not changed. Connection is also similar. However, manufacturers went to upgrade the heating places, so they have different power:

the first burner has a smallest power - 0.4-1 kW;
two burners have an average power - approximately 1.5 kW;
the fourth burner has the highest power - up to 3 kW.

Thus, the total energy consumption reaches 7 kW. However, exist electric surfaces with additional properties, including:

with the possibility of adjustable increase common Square heating for each point - additional rings around the disks;
with the option of combining two adjacent burners for working with disadvantage of non-standard oblong shape - hussymen and the like;
from large quantity Heating points, that is, not four, and more, for example, six.

Accordingly, the total power may increase to 10 kW.

Of course, with such indicators it is necessary to consider in advance how such a demanding energy technique will be eaten, otherwise the wires in the wall may unexpectedly be overwritten during the operation of the panel. To restore, you will have to look for a break point, open the wall, connect the wires and close the wall again. This can be a big problem, so discuss with a specialist with the possibility of your power grid.

For apartments in old houses of Soviet buildings, it is not recommended to acquire electric stoves total capacity Over 3.5-4 kW. In the houses of the modern building it is allowed to install electrical equipment with an energy consumption of up to 10 kW.

Also should not be discounted and other electrical equipment that creates a load on your home network. These include a boiler for water heating, washing machine, Iron, electric kettle, microwave, laser printer. Each or a long time consumes a large amount of electricity, or creates a short-term, but tangible peak load, or both immediately. Try to make your new electric stove work simultaneously with other powerful consumers.

Many modern electrical cooking panels have burner heating sensors that warn you about burning the burn when touching the surface of the panel. If you have such an opportunity, try to purchase exactly such a model. First, it will increase the safety of the work at the slab, and secondly, knowing in advance that the drive is still hot, you can put another dishes on it and save on electricity.

- most modern view Equipment for heating food in the kitchen. Its average power is about 7 kW. However, note that this is the consolidated power of the device.

Due to the fact that cooking on the induction surface takes a minimum of time, the simultaneous operation of all disks is almost not happening. And even if it happens, a short period of peak energy consumption is rapidly replaced by inaction, since cooking has already ended - the soup ventilated, the fish dugly, the kettle boiled.

Thus, although the power of the induction plate is equal to the power of conventional electric stoves, due to heating exclusively the bottoms and the lower part of the dishes (and not air under it), the electricity is consumed only on heat treatment. It is important to note that energy savings requires the use of special dishes in the cooking.

Induction panels - most economical view Kitchen equipment from all available today, although they differ high costs.

Gas cooking panel

Special power meter To determine this parameter at the household gas stove, it is not easy to find, since gas is not electricity, and at home to measure the amount of energy spent (or obtained) in the process of burning hydrocarbon fuel, it is impossible.

So, to set the power of such a panel, the direct count can be replaced by another method, for example, by the amount of gas that has passed through the counter. Calorific value natural Gas. It is 8-11 kW per hour / m. cube It is possible to estimate the quality of gas in the kitchen only subjectively, but the minimum and maximum definitions are still realistic, based on such parameters:

the approximate power of one burner of the standard household gas cooking surface is estimated at about 2-2.5 kW;
total calorific value total gas device On 4 burners approximately equal to 8-10 kW.

The reduced power of small burners is compensated by the increased heat efficiency of the highest burner.

At the same time, the power of the burner depends on its diameter, which can be seen on the table (data is given for a state when the burner's gas valve is completely open):

Diameter of the burner, mm	50	75	130
power, kWt	1	2	3,5

For the most common variant (one place by 50 mm, two to 75 mm and one by 130 mm) total power will be 8.5 kW.

Given this parameter as power, you can make a competent selection of the cooking panel. Since the market suggests various options, Everyone can choose an optimal model. It should be borne in mind that overpaying to buy an energy-saving unit, in the future you can long years Save on energy.
