The power of the electric stove. How to cut energy costs

The twenty-first century gives kitchen lovers a great opportunity to use convenient technology.

Among them are induction cookers, which many people already know about. Such a device does not waste electricity simply, for example, on heating the surface of the furnace.

Influence of the principle of operation on power consumption

To understand how two concepts are interconnected - performance and power consumption, it is necessary to deal with each aspect separately.

How an induction cooker works

Device applies to electrical structures and has a familiar look.

However there is no heating element under the glass-ceramic surface. Instead of them the device is equipped with high-quality electromagnetic coils made specially of copper.

They are needed in order to create a magnetic field. When it happens created electricity, which passes through the dishes. Accordingly, the food is heated.

Reference! Heating does not occur through the surface, so the dish is cooked quite quickly.

In addition, there is block that controls the process of work. With its help, the presence of an object on the plate is recognized. It turns the same coils on and off.

How the principle of operation affects energy consumption

Dealing with this issue is easy and simple. From the above we know that energy is not distributed to the entire surface area, but only to the burner. Therefore, and Much less electricity is used.

In conventional stoves, heating elements at the beginning of work increase the temperature of the entire body, then the heaters, and only in the very last place - the dishes in which the product is located. Such a way to warming up and making food takes a huge amount of time. From this it can be concluded that and energy has to be spent on a large scale.

Therefore, if we compare induction cooker and a unit with a heating element, the advantage of the first is noticeable.

Several liters of liquid, the first of them will warm up in half an hour, and the other in a matter of minutes, provided that the power will be the same for both.

Even with the most powerful unit induction hob will remain the most economical option of all possible as it reduces cooking time by 15-20 minutes.

Ability to adjust power

An additional advantage is the power adjustment. Touch controls on induction cooktops. You must press your fingers on the icons presented, so you will not find any buttons on the stove.

With one touch you can install required power rather than apply pressure several times.

The control is very smooth, therefore, the quality of the dish is guaranteed.

Such an action is instantaneous, and setting up a small fire on other devices is not easy to perform.

The power control allows you to save extra by choosing a low power level.

Pros and cons of an induction cooker

Before making an expensive purchase, you need to carefully analyze all the pros and cons.

Advantages

The main advantage of modern induction surfaces is economical technology.

Due to the fact that the energy does not evaporate into environment, but served straight to the cooking utensils, electricity consumption is significantly reduced compared to other types of boards.

Besides efficiency usually reaches 90 percent.
It means that all activities are focused only on cooking, what affects the speed of the process.
To all the pluses should be mentioned security. When electricity is used up, only the hob that you turned on works. Hence, chance of getting burned is reduced to zero, even if, for example, your hand will lie on the surface.

Reference. Savings start from the first moment the device is turned on.

This is achieved through several steps.

Heating occurs instantly.
Warmly formed on the bottom surface of the used utensils, used only for cooking.
The self-acting switch works at removal of an object from a plate surface.

disadvantages

The disadvantages include use of electricity to work with this type of plate.

If you are the owner gas equipment, then existing electrical wiring may not be sufficient powerful. And replacing it yourself can be quite a difficult option.
The device is capable of providing small negative impact per person. Of course, you should not be so afraid of this, harm is done in small doses. But still, it is advisable not to neglect this and adhere to some simple rules.

Do not come into close contact with the unit. Try to stay as safe as possible- not less than half a meter (optimal - 30 centimeters).
If a person can avoid harm, then other devices may fall under significantly damage. This applies to similar kitchen appliances, various cell phones and other gadgets. But it will not be so dangerous for them if removed to a safe distance.

Consumption consumption per month

Let's compare the characteristics for individual types of hobs. Let's take an electric stove with glass ceramics, gas and induction as an example. The last of them will consume one and a half times less than the rest, namely 0.35 kW (why exactly is indicated at the beginning of the article). When heated instantly, they have the following mechanism: when the current is turned off, the coils will not produce magnetic flux, that is, the dishes will not heat up.

If it is regulated, then changes will occur instantly, since heat generation will be directed exclusively to specified place- one burner.

ATTENTION! To minimize energy consumption, you need to purchase special dishes (pots, pans), which are designed specifically for this type of stove - induction.

Consumption calculation

Water heating:

electric stove - 30 min. = 1.7 kW / h.
Induction hob - 5.5 min = 0.32 kWh.

Monthly expense:

electric stove - about 460 kW / h.
Induction panel - about 155 kW / h.

We conclude: induction device more efficient use of electricity you will also have to pay less for electricity than it would be with other stoves.

Now you know how much the induction panel consumes. This will help decide whether such a technique is needed or not.

It is worth being prepared for the fact that it will require a huge amount of electricity. This device compared to others home appliances has the highest power. For this reason, the installation of such a stove requires separate sockets and lines. For houses where there is no gas equipment, and only electric stoves are used, preferential tariffs for electricity are set. So, what is the standard power electric stove?

Electric stove with two cast iron heating elements most often has a power of 2000W, and a similar device with 4 elements - from 5000W. If a four-burner stove, then the value will start from 10400 watts. Naturally than more number heating and other functional elements, the greater the indicator of electricity consumption.

When choosing a device, it is worth remembering that the power of the electric stove also affects the heating rate of the burners.

A separate place among electric stoves is given to devices with induction heating elements. Such equipment also has a cost. But if it is used correctly, then the energy costs will be less. This is ensured by:

heating occurs very rapidly;
the heating switches off automatically when the dishes are removed;
special dishes do not allow heat loss.

Dependence of power and energy consumption

Each owner wants to know how much electricity his device consumes, taking into account its functionality. A conventional electric stove, which has four cast iron burners, consumes on average approximately 4 to 8 kilowatts per hour. But this indicator is calculated on the condition that all burners work together, respectively, if only one is turned on, consumption is significantly reduced.

Every housewife should remember that with proper save electricity consumption. With a few rules, this is easy to do:

in order not to lose excess heat, the diameters of the burner and the pan should match as much as possible;
the smooth bottom of the dish improves heat transfer;
cast iron burners can be turned off a little earlier, as they cool down for a long time, respectively, cooking continues after turning off.

Choosing cookware with the same burner diameter

Also, to achieve maximum savings, it is worth knowing the power of individual functional elements of the device. Below are the approximate values of this indicator of the main components of the plate:

burner with a diameter of up to 14.5 cm - 1 kW;
heating element with a diameter of 18 cm -1.5 kW;
electric hotplate with a diameter of 20 cm - 2 kW;
lighting - 15-20 W;
Grilled heater - 1.5 kW;
Heating element from below - 1 kW;
TEN from above - 0.8 kW;
spit motor - 6 watts.

It is easy to come to the conclusion that the electric stove consumes the most energy when it is working. large burner, but do not forget that the cooking process on it is accelerated and goes much faster.

Energy classes

Each manufacturer is trying to increase the competitiveness of their products. Therefore, they strive to reduce energy consumption as much as possible. Electric stoves, like any appliances, are divided into classes according to electricity consumption. Designation is done with Latin letters from A to G, starting from the highest. Today you can see the following notation: A++ or A+++. This means that the energy consumption figures are higher than class A.

The class depends on the amount of energy consumption when reaching set temperatures. The largest number ovens consume energy, but with improved insulation, which will reduce heat loss, significant savings are achieved.

Network connection features

When it is worth considering its high power, so you must adhere to certain rules. To install such a device, you will need:

power outlet 32A;
introductory machine more than or equal to 32A;
three-core copper cable, which has double insulation and a cross section of more than 4 sq. mm;
RCD not less than 32A.

To not happen contact overheating, each element of the wiring must be of high quality in compliance with safety regulations and installation instructions.

According to experts, the power consumption of a stove not only depends on the characteristics of the appliance itself, but to a greater extent on the conditions of use.

Induction cooker power from 3 to 10 kW

The power of the induction cooker is the parameter that is important and decisive when choosing equipment Quite often, when purchasing a cooking appliance, attention falls not only on the design of the hob and electric stoves in general, but also for power, especially if the model of an induction cooker is purchased. This equipment has become popular recently in many countries, as it has a lot of positive aspects and, most importantly, efficiency, ease of use, and the like. technical specifications, as the energy consumption of an electric furnace per month. Due to the fact that the technique was created according to modern technologies, it can consume a minimum of energy, giving the maximum result.

Rated power of the electric stove and the general arrangement of the equipment

The model of the electric stove, on which induction burners are installed, has a new way of heating food, which allows you to heat or cook a dish in the shortest possible time. The peculiarity of these household electric stoves has magnetic field, which is supported by high-frequency coils, transmitting to the surface of the dishes induction current that performs heating.

The hob of an electric stove, for example,Bosch, has:

temperature sensor;
Corps;
control panel;
Power part.

For an induction cooker, it is best to purchase special dishes

Since the hob acts on a certain point or, in other words, not on the surface of the cookware installed on it, everything that surrounds this place remains completely cold. This is very useful for those who have small children at home or are close to such a problem as burns on the surface of the burners.

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

Ware is selected, which has a high magnetic permeability and has a fixed value in resistivity. The best option there will be dishes made from a ferrimagnetic cloth, as it fully meets all the requirements.

Selecting the power of the hob

Modern hobs or induction cookers, in which an oven is additionally installed, have a connection power in the range of 3-10 kW. The figure directly depends on how many burners are present on the surface, as well as on their total performance. Basically, the electric stove has 4 burners, which have different size for ease of preparation.

AT standard model burner power big size is approximately 2-3 kilowatts, and for 2 small average performance 1.5 kW is considered. On a small burner, the power is 1 kW.

It is important to use burners in accordance with their parameters and recommendations from the manufacturer. To be more precise, it is forbidden to put a large pan on a small circle. All circles heat products independently of each other, which in no way affects their performance and what consumption this equipment will carry out. There are many advantages to induction cookers that make them the choice of the world.

When choosing an induction cooker, pay attention to its functionality and technical characteristics.

These include:

Possibility of fast heating and cooking;
Multifunctionality;
Lack of opportunity to get burned;
Ease of use.
High level of efficiency;
Availability circuit breaker when removing dishes;
No dependence on what will be the power consumption relative to the voltage in the network;
Economy in consumption;
Excellent technical performance.

Unfortunately, technology is not without its drawbacks, but they are not so significant and sometimes fade into the background. It is required to select special dishes. Repairs can only be carried out by a master. The stove emits radiation to other appliances installed in the kitchen.

Induction cooker: how much electricity is required to work

It is sometimes very difficult for some people to change the good old electric stoves with ordinary burners to new and high-tech equipment, however, if you look at these models more carefully and become familiar with the principle of operation and electricity consumption, then your opinion may change quickly.

Basically, does not affect the purchase of something:

How much does the product weigh?
What is the design;
Is the model equipped with an oven, or is there an additional connecting part for cooking in a closed space;
How much does the product cost.

First of all, the energy consumption of electricity per hour and, accordingly, the total amount of consumption of this resource is important. It is worth noting that a conventional four-burner induction hob has a power of 3.5 kW. Similar power for electric stoves with heating elements.

The induction cooker has a lot of positive qualities

If we compare the efficiency, it will take 30 minutes to heat 2 liters of water on a conventional stove with heating elements, and only 5.5 minutes when using induction.

It can only be concluded that the energy consumption in the second case will be 6 times less. Depending on the type of burner on the induction cooker, not only the specific energy consumption is carried out, but also what products are preferably cooked on them. On the burner small size, the power, which is on average 0.4-1 kW, is mainly used for preparing milk porridge, coffee or stewing meat. On the largest burners, food is cooked in a large container. Medium burners, suitable for cooking meat dishes, vegetables, cereals and other side dishes for the whole family.

There are fast heating burners, they have the largest connection power, which makes it possible to cook with their help quickly and as tasty as possible. There are models in which the burners are of a double type, which allows you to put non-standard-sized dishes on them for use, for example, oblong ones. The total power of connecting induction hobs directly will depend on the model, number and size of burners. It is much easier to use stoves with at least 4 burners, which allows you to cook several dishes at once.

Optimum energy consumption of the induction cooker

Even gas stove an hour of work will require a lot more resource than when using stoves in which the type of induction surface is installed. The operation of such a product, as already noted, directly depends on how well the high-frequency coils function, on average 30-60 kHz, due to which an electromagnetic field is created. The peculiarity of this mechanism of work lies precisely in reducing the level of energy consumption, which primarily affects the costs from the budget to pay for such a resource.

A special panel monitors the cooking process, due to which:

Dishes are recognized;
The power of the induction field is adjusted;
The presence of dishes on the surface is monitored and, when it is removed, the device turns off.

Induction cookers have low energy consumption

To demonstrate the real power of an induction cooker and in order to recognize how much energy it really takes to cook food, it is enough to conduct a small experiment. It is described above, and this is a banal boiling of water. You can take milk porridge or coffee as the basis for cooking, but in any case, the cooking time will be much lower than if you do it on a standard stove.

Almost all induction cooker models have low energy consumption, which makes these cookers in demand all over the world.

Power consumption of the induction cooker (video)

It is worth noting that when buying, you need to pay attention not only to the power, but also to the quality of the equipment, and it is advisable to give preference to those stoves that are created well-known manufacturers. This will allow you to get really high-quality equipment for cooking.

One of the first questions that arises is how much power the purchased device should have. This is important factor, which will help determine which panel is better to choose - gas, induction or electric. What depends on the power of the unit and how much it is different models, find out more.

What determines the power of the hob?

The power of the hob is an important parameter for choosing an appliance for three main reasons:

The speed with which your dishes pass depends on the power. heat treatment. Agree that it is better when there is an opportunity to cook dishes as quickly as possible.
Modern stoves have burners of different capacities, and this is very convenient. If you only need a small amount of heat, why waste extra gas or electricity on useless air heating in the kitchen. However, the reverse side of the issue should also be taken into account - the power of the largest burner should also be sufficient to quickly cook a large pot of soup.
On the modern kitchens Often, air conditioners are installed. When heat energy is released in too large quantities, the load on the air conditioner increases accordingly. At the same time, the extra costs for both heating the air and cooling it are completely unjustified.

So, it is worth choosing a hob with such power that the cooking time is fast, but the heat generated is optimal.

Electric hob

Electrical appliance traditional design consumes the most electrical power of all the types under consideration, so we will start the review with this option.

The most widespread on the market in our time have received stoves with four burners. Thus, the standard number of heating points has not changed over the decades of the existence of home stoves. The connection is also similar. However, manufacturers have gone to the modernization of heating places, so they have different power:

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

Thus, the total power consumption reaches 7 kW. However, there are electrical surfaces with additional properties, including:

adjustable zoom total area heating for each point - additional rings around the disks;
with the option of combining two adjacent burners to work with dishes of non-standard oblong shape - goose-cookers and the like;
with large quantity heating points, that is, not four, but more, for example, six.

Accordingly, the total power can increase up to 10 kW.

Of course, with such indicators, it is necessary to think in advance how such energy-demanding equipment will be powered, otherwise the wires in the wall may suddenly burn out during operation of the panel. To restore, you will have to look for the place of the break, open the wall, connect the wires and close the wall again. This could become big problem, therefore, discuss with a specialist the capabilities of your electrical network.

For apartments in old houses Soviet-built it is not recommended to purchase electric stoves with a total power of more than 3.5-4 kW. In houses modern building installation of electrical equipment with power consumption up to 10 kW is allowed.

Also, do not discount other electrical equipment that creates a load on your home network. These include a boiler for heating water, washing machine, iron, electric kettle, microwave oven, laser printer. Each of them either long time consumes a large amount of electricity, or creates a short-term, but tangible peak load, or both at once. Try not to run your new electric stove at the same time as other powerful consumers.

Many modern electric hobs have burner heat sensors that warn you of a burn hazard if you touch the surface of the hob. If you have such an opportunity, try to purchase just such a model. Firstly, this will increase the safety of working at the stove, and secondly, knowing in advance that the disk is still hot, you can put other dishes on it and save on electricity.

- most modern look equipment for heating food in the kitchen. Its average power is about 7 kW. However, please 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 discs almost does not occur. And even if this happens, a short period of peak energy consumption is quickly replaced by inactivity, as the cooking is already over - the soup is cooked, the fish is fried, the kettle is boiled.

Thus, although the power of an induction cooker is equal to the power of a conventional electric stove, by heating only the bottom and bottom of the cookware (and not the air underneath), electricity is consumed only for the heat treatment of food. It is important to note that saving energy requires the use of special dishes in cooking.

Induction hobs are the most economical type of kitchen equipment available today, although they are expensive.

Gas hob

It is not easy to find a special power meter for determining this parameter near a household gas stove, since gas is not electricity, and it is impossible to directly measure the amount of energy spent (or received) in the process of burning hydrocarbon fuels at home.

So, in order to establish the power of such a panel, direct counting can be replaced by another method, for example, by the amount of gas that has passed through the meter. Calorific value natural gas is 8-11 kW per hour / m. cube It is possible to evaluate the quality of gas in the kitchen only subjectively, but it is still realistic to determine the minimum and maximum values, based on the following parameters:

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

The reduced power of the smaller burners is compensated for by the increased heat dissipation of the largest burner.

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

Burner diameter, mm	50	75	130
power, kWt	1	2	3,5

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

Given such a parameter as power, you can make a competent choice of the hob. Because the market offers various options, everyone can choose the best model for themselves. At the same time, it should be borne in mind that having overpaid on the purchase of an energy-saving unit, in the future you can long years save on energy.

In contact with

Hello! After many years of use, my electric stove spoils the look of the renovated kitchen. I want to change. Lot good reviews about embedded induction panels: beautiful, economical. What power of such a stove is optimal, does it consume less electricity, by how much? What to look for when buying?

The perfect choice! So you can call the induction cooker. This type hobs completely safe: remaining cold, it heats only the dishes on the burner. If there is no pot or pan on the stove, it simply does not turn on. It is impossible to burn yourself on such a panel: the heating automatically stops at the same time as the pan is removed. The burner itself cools down in just 10-15 seconds.

Nothing burns on the ceramic surface. To maintain cleanliness, it is enough to wipe it with a soft cloth with a special agent.

Energy consumption can be calculated

Let's compare the consumption for boiling water on burners of the same power of conventional and induction electric stoves: kettles of 2.5 liters, power 2 kW, boiling time 30 minutes. and 6 min., spent 1 kW and 0.2 kW, respectively. Savings - 0.8 kW. "Score" 5:1 in favor of induction.

Modern stoves of this type have a power of 3.5-10 kW. For an apartment, especially in old houses, the smallest one is optimal - it does not need any special wiring or permission from the energy supply organization. Homeowners can install more powerful appliances.

The number of burners can be determined based on the needs of the family and the area of \u200b\u200bthe kitchen. 4 burners are more convenient, 2 can be. Expensive models differ from budget ones in the set of functions, the number and method of adjusting the heating: rotary switch, touch control or remote control.

Quite democratic in price (from 13,000 rubles) Hansa BHI64383030 4-burner stove has 9-stage heating adjustment, touch control, overheating protection, there is an increase in burner power by 1.5 times (Booster) and other functions. Plugs into a home network outlet. Actually, functionality, not power, determines ease of use. But, the more complex the functionality, the higher the price. True, wider and room for creativity.

What will require attention when choosing

At home: the presence of magnetized dishes with a flat bottom. Irregularities increase energy consumption and can cause the hob to “sing” due to uneven heating. Enameled, cast iron, steel containers are suitable, the bottom of which holds permanent magnet(it is the bottom that heats up, the boiling liquid heats the walls). If not, you can purchase as a temporary replacement special utensils, steel discs that transfer heat from the burners. Carefully measure the intended installation location.

In the store: select the type of hob: dependent or independent. The former work only together with the oven and cannot be installed separately, since the control knobs are located on the front panel oven. Second - install anywhere. The presence of the edging of a ceramic plate - the edges of the surface - is the most vulnerable point: upon impact, chipping is possible.

Important! The use of aluminum or copper cookware may cause permanent stains on the ceramic surface. And yet, ceramics are destroyed by sugar. Spilled sugar or syrup must be removed immediately.
