Hob power: induction, electric, gas

At choosing a hob One of the first questions is how much power the purchased device should have. This is an important factor that 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 for different models, find out further.

What determines the power of the hob?

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

• The speed with which your dishes go through heat treatment depends on the power. Agree that it is better when it is possible to cook dishes as quickly as possible.
• Modern stoves have burners of different capacities, and it is very convenient. If you need only a small amount of heat, why spend extra gas or electricity on useless heating of air in the kitchen. However, the flip side of the question should be taken into account - the power of the largest burner should also be sufficient to quickly cook a large pot of soup.

• Modern kitchens often have air conditioning. When heat is released in too large quantities, the load on the air conditioner increases accordingly. At the same time, the extra costs for heating the air and cooling it are completely unjustified.

Electric hob

An electric device of a traditional design consumes the greatest electric power of all the types under consideration, so the review will begin with this option.

The most common in the market today are four-burner cookers. Thus, the standard number of heating points over the decades of the existence of home stoves has not changed. Connection also similar. However, manufacturers went for the modernization of heating places, so they have different capacities:

• the first burner has the lowest 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 energy consumption reaches 7 kW. However, there are electrical surfaces with additional properties, including:

• with the possibility of adjustable increase in the total heating area for each point - additional rings around the disks;
• with the option of combining two adjacent burners for working with dishes of non-standard elongated shape - goose bowls and the like;
• with a large number of 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 Demanding equipment in terms of energy, otherwise the wires may burn out unexpectedly during operation in the wall. To recover, you will have to look for a cliff, open the wall, connect the wires and close the wall again. This can be a big problem, so talk with a specialist about your power supply.

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

Many modern electric hobs have burner heat sensors that alert you to the danger of burns when you touch the surface of the hob. If you have such an opportunity, try to purchase just such a model. Firstly, it will increase the safety of work 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.

Induction hob

Induction hob - The most modern type of 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 almost does not occur. And even if this happens, a short period of peak energy consumption is quickly replaced by inactivity, since cooking has already ended - the soup has been cooked, the fish has been fried, the kettle has boiled.

Thus, although the power of the induction cooker is equal to the power of a conventional electric stove, due to heating solely the bottom and bottom of the dishes (and not the air below it), electricity is consumed only on thermal processing products. It is important to note that saving energy requires cooking special utensils.

Gas hob

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

So, to establish the power of such a panel, direct counting can be replaced by another method, for example, by the amount of gas passed through the meter. The calorific value of 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 the minimum and maximum values ​​can nevertheless be really determined 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;
• the total calorific value of the entire gas device for 4 burners is approximately 8-10 kW.

The reduced power of the small burners is offset by the increased heat output of the largest burner.

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

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

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

Given such a parameter as power, you can make a competent choice of the hob. Since the market offers various options, everyone can choose the best model for themselves. It should be borne in mind that by overpaying for the purchase of an energy-saving unit, you can save on energy for many years to come.
