Electric stove power
Before purchasing an electric stove, people are faced with the question of choice - it is important not to make a mistake, because this kitchen appliance will have to serve for many years. One of the main aspects that you should pay attention to when purchasing is power. The electric stove is the number one consumer of electricity in the house. For optimal use, you need to know what power kitchen appliances are produced by manufacturers and how this indicator affects the operation of the unit.

Standard power ratings for an electric stove
Currently, there are classic stoves - with traditional burners. The heating element is a spiral. They heat up and cool down quite slowly. Glass ceramics heats up more evenly and takes less time to cool down. The efficiency of such household appliances is quite low.
Cookers with induction burners are also available. In them, heating occurs due to vortex flows, which are formed by a high-frequency magnetic field of 20–100 kHz. In this case, it is not the burner that heats up, but the dishes sitting on it. The working area is heated to a maximum of 60 degrees. This is its significant advantage, since it is impossible to get burned when using such equipment.
The power consumption of appliances increases with the number of burners and their diameter, and this figure is also affected by the presence of other heating elements:
- 2 cast iron burners will take 2000 W;
- 4 – from 5000 W;
- 4 burners with induction heating may require from 10400 W.
But this is provided that you have to use all the burners at the same time, and this happens extremely rarely - only when you need to cook a large amount of food. Usually one or two work.
How power affects operation and energy consumption
When choosing a stove, you should take into account that its power will affect the heating speed and the number of fully functioning burners at the same time. The oven will require the most energy. But high-quality oven insulation will reduce the loss of electricity and money.
The user can optimize the electrical energy consumption of his stove if:
- will use dishes with a flat bottom - this will improve heat transfer between the burner and the pot or pan;
- will cook food in a saucepan or frying pan with a diameter approximately equal to the diameter of the burner;
- When using a stove with cast iron burners, turn it off before the cooking is finished - cast iron retains heat for a long time and after turning off the food will continue to cook for some time.
Many people ask the question: “How many kilowatts does an electric stove consume?” The approximate amount of energy that, on average, a household appliance will consume per month is:
- motor installed on the grill spit – 6 W;
- oven lighting – 15.0–25.0 W;
- burner with a diameter of 14.5 cm – 1.0 kW;
- with a diameter of 18.8 cm - 1.5 kW;
- diameter 20 cm – 2.0 kW;
- upper and lower heating elements in classic stoves 0.8 and 1.0 kW, respectively;
- The heating element installed on the grill in the oven is 1.5 kW.
A large burner requires the most energy to operate, but its heating rate is significantly higher than burners of a smaller diameter.
REFERENCE! Currently, manufacturers label all household appliances according to economic efficiency classes. The less energy required to achieve a given temperature, the higher the class. The marking is indicated in English letters: A, B, C... G. At the same time, the marking “A” indicates high energy efficiency. There were even classes A+, A++ and A+++. This is a label designation for the most cost-effective household appliances. Modern stove models can be cheaper to operate than outdated ones.
Induction hobs use more power. But there are advantages that allow you to save money when using the device correctly:
- When using not only special cookware, but also cookware with ferromagnetic properties (this includes even outdated enamel-coated pans), less heat loss occurs. If the magnet attached to the bottom of the container sticks, the cookware is suitable for induction heating.
- Quickly removing the pot or pan from the stove will also save money, because in this case the burner immediately stops heating.
- Some options that can be equipped with an induction heating stove also provide the opportunity to save money: auto shut-off when boiling, timer.
To operate 4 induction burners, up to 7 kW is most often required. 3–5 kW is consumed for heating. It should be noted that heating such a stove takes half the time.
They are usually equipped with a display.It displays modes and power levels. Thanks to the low temperature of the working surfaces, nothing will burn to such a stove. Therefore, it is easy to keep clean. If you try to use a cookware with a diameter that is very different from the diameter of the burner, it will not turn on. It won’t turn on when you try to place dishes with a diameter of less than 100 mm on it.
REFERENCE! There are also combined plates. They have induction-heated burners with installed heating elements. In them, as in any other equipment, the power consumption will be specified in the technical instruction manual.
Features of connecting the stove to the network
Since the electric power of the stove is quite large, when designing electrical circuits in the house, it is imperative to take into account the maximum power of the stove. When installed, it requires a separate line and socket.
You will also need:
- three-core cable with double insulation and a copper cross-section of at least 4 square millimeters;
- residual current device of at least 32 A;
- power socket 32 A;
- input circuit breaker of at least 32 A.
If the user is not an electrician, it is better to invite a specialist to install the electric stove (you should not forget to ask him for a certificate of completion), since all connections must be made very well. The high power consumption of a household appliance can lead to overheating of the contacts and a short circuit.
Provided you choose a stove of a high class of economic efficiency, perform correct installation and observe optimal operating conditions, you can not only save money, but also enjoy the use of modern household appliances.
