An electric kettle has recently become a popular household appliance that many use to heat water for tea, coffee, and other hot drinks. But before you start using it, it's worth finding out how much electricity an electric kettle consumes. Knowing these indicators will help to significantly save energy and money.
Power Level Indicators
Before you start using an electric kettle, you should find out what power consumption it has, usually it ranges from 700 to 3000 watts. Despite the fact that this parameter is considered decisive, still the level of energy consumed per month may depend on many factors:
- volume indicator of a flask or capacity;
- a kind of heating element;
- water quality indicators;
- number of times warming up;
- water volume.
Of course, these are not all the conditions on which the consumption of energy can depend. However, they are considered the most common.
Types of heating elements and heating rate
The power consumption of an electric kettle may depend on the type of heating element. The following types of heating elements are usually installed in electric kettles:
- TEN with an open type. It has the form of a spiral, is installed in the device and is in direct contact with the liquid. Devices with a heating element of this type usually work in silent mode, while the water is heated very quickly. On average, the whole process takes 2-2.5 minutes;
Open TEN
- TEN with the closed type. This heating element is a heating plate, which is installed on the bottom of the device. Water heating takes a little longer, unlike devices with open heating elements. Full warming up of water occurs in 3-3.5 minutes. Also warming up can be noisy. But in such devices a minimal amount of scale is formed.
Closed heating element
The effect of the body material of electric kettles
The heating rate can also be affected by the material from which the device body is made. When buying, be sure to pay attention to this characteristic, of course, if you want energy consumption to be minimal.
So, these devices are usually made from the following types of bases:
- metal. Kettles, which are made of a metal base, have a high heating rate. However, during the working process, the case warms up very much, which requires additional energy consumption;
- glass. Devices made of glass have quick heating. However, the glass base does not warm up very much;
- ceramics. Devices made of a ceramic base have less rapid heating. But this base retains heat much better. For this reason, water in ceramic appliances can remain hot for a long time.
The amount of electricity consumed
Almost everyone often has a question, how much electric energy does an electric kettle consume? Many simply do not believe that it can occupy the largest part of the expense of funds to pay for electric energy. The average power consumption of this device is 1.5-3 kilowatts per hour.
For example, suppose that the average warm-up period is 3 minutes, and if you use the appliance about 4 times a day, you can calculate the average electricity consumption per month using the following formula:
3 * 0.2 * 30 = 18 kW / month.
Table for comparison with other devices
If we consider the energy consumption indicators of other devices, then the kettle they are small. However, you should pay attention to the period of operation of other devices, many of them work throughout the day. From this we can conclude that the electric kettle is capable of spending a large amount of electricity in a short period of time.
Energy Saving Tips
An electric kettle is an uneconomical device that is capable of winding electricity in one boil, like a refrigerator for several hours of operation. But if you follow important recommendations when using, you can significantly reduce energy consumption per hour.
The consumption level can be easily calculated on the counter.
So, here are a few useful tips:
- If you are not currently using a kettle, be sure to unplug the plug from the outlet. It is worth considering that in standby mode, a technician can consume a little electric energy;
- boil is the amount of water that will be required for one tea party or for other purposes. Pay attention to the fact that boiling two liters of water will require much more energy than heating one liter of liquid. If you want to drink only one glass, then you do not need to pour water to the maximum level;
- be sure to regularly clean the heater and the inner surface of scale deposits. Large layers of lime increase the period of boiling of the liquid, which leads to a large expenditure of energy. Also, the heater can quickly become unusable when large scale layers form on it.
Many people think that it is much more economical to heat water on an electric stove. In their opinion, this type of device consumes much less energy. However, this is not entirely true: on this device, the heating will be quite long, but heating the water in the electric kettle will take several minutes. Consequently, the energy costs will be much less.
The main thing is to be able to use these devices correctly, then the energy consumption will be small. Many consumers confidently claim that they are heated quickly, in just 3-4 minutes. And they consume not so much, but on condition that they will be used no more than three times a day.
