Dishwasher how many kilowatts power

Consumed power of dishwashers

The power of modern dishwashers can be from 0.4 kW (class A) to 2.7 kW (class G). On average, it is 0.7 kW (class A). The power consumption depends on the size of the tank for washing, the amount of used and heated water, such as drying dishes and many other factors. We will figure out this parameter further.

Any dishwasher has devices consuming electric energy. This is:

  • Heat heating heater (Ten), heating water. This is the main consumer of energy in the dishwasher. Its power can reach 2.8 kW. Thus, the power consumption of the device depends on the two parameters. On the power of the heater himself and the need to use it. If the dishes are oily, it is difficult to wash it, so you need to heat a lot of water to a temperature of 65 ° C, and the power consumed by the sink increases. If the dishes are almost clean, you do not need to turn on the maximum temperature. 35 ° C will be enough.
  • Water pressure pump. Usually has a power up to 100 watts. Pressure in the house water supply network is usually not enough to a level sufficient for effective washing dishes. So, for the washing process, you need to raise the pressure, which is carried out by the circulation pump. In this case, everything is simple. The longer the sink works, the more energy the pump electric motor uses. Depending on the duration of the selected program, the consumed power will also change.
  • Water pump. The indicator of its power is approximately 25-30 watts. After the operation to clean the dishes is completed, dirty water must be removed from the device. This work is performed by the drain pump.

So, the power of the dishwasher depends on how much energy is used by its “components”. It is worth considering that in addition to the main details listed above, the unit may have additional “components” depending on their characteristics.

In addition, the power depends on the following factors:

  • The amount of water consumed. Borderline values ​​for a standard sink operation. From 7 to 15 liters. Naturally, the car will be able to heat up to the desired temperature a smaller volume of water and twice as fast and half.
  • Duration of washing procedure. Temporary interval can fluctuate from 40 to 260 minutes. Most of this time the pump will work by consuming electricity.
  • Sizes of bunker for washing. Sinks are of two standard sizes. 45 or 60 cm wide. Smaller dimensions usually mean less energy consumption.

So, many factors determine the power consumption of the machine, so it is necessary to take into account its capabilities and the conditions for its commissioning.

What is energy consumption and energy efficiency class?

For you as a buyer who wants to save on utilities, it is important to pay attention to the electricity consumption or class.

PM electricity consumption is the amount of energy that spent a dishwasher for 1 washing cycle (one load).

This value is measured in WT/h or kW/h. It is this value that you see in a monthly payment.

When visiting a store for buying a dishwasher on windows, you can see stickers with a class designation. This indicator is assigned depending on the amount of electricity consumed by PM. Such a classification allows you to firmly navigate when choosing and highlighting the most economical technique in terms of electricity consumption.

In the table below you can see the classification by classes and their designations.

Energy consumption class Electricity consumption in kW/h and characteristics
A or a 0.4-0.6 kW/h. The most energy.Efficient PM.
A 0.75-1.05 kW/h. One of the most economical PM.
B 1.056-1.38 kW/h. These are household appliances with an average level of energy efficiency.
C 1.38-1.72 kW/h. Energy efficiency is slightly lower than average.

On the market, the class A and B dishwashers are most often found.

The power consumption of the dishwasher

Unlike other household appliances, where high power indicates the efficiency of work, in the dishwasher everything is exactly the opposite. Here high power is more likely a drawback than the advantage. In Western countries, where saving in everything has long come to the fore, they try to buy low.Power dishwashers to reduce electricity consumption.

What depends on the power indicator

A large amount of electricity goes to heating water, hot drying and the operation of the pump. If highly effective technologies were used in the production of the dishwasher, then it does not need a large amount of energy. On the contrary, such a model will be small, trying to earnestly use resources.

The power consumption of the dishwasher depends on its class. The most economical can be considered the dishwasher of class A, B and C: they have the highest rating, as they consume only 0.67-1.5 kW.

Class D and E models receive an average assessment, as they have higher power. Finally, representatives of groups F and G are considered the most ineffective in terms of energy consumption. Their average indicators from 2.3 to 2.7 kW.

These include old dishwashers usually include.

dishwasher, many, kilowatts, power

In turn, economical models can differ significantly among themselves in terms of energy consumption:

It is obvious that the power consumption of the dishwasher of the third group is a third more than the first. Excellent argument towards buying a higher efficient model. However, you can save in another way.

Electricity savings

Since the main amount of electricity goes to heat water, sometimes it is recommended to connect the device directly to the pipe with hot water.

Like, so much less than the kilowatts of energy consumed for the dishwasher will go to the work of the dishwasher.

And indeed: the dishwasher takes water from the water supply, compares its temperature with the right one and heats it only if necessary. But will it help you save?

It all depends on how hot water is in your house. If a boiler heats it up, it is advisable to compare the number of KW he needs with the case that needs a dishwasher. If your drive electric heater is more economical than a dishwasher, then you can use hot water.

If you are a resident of an apartment building and use a central water supply, again pay attention to the cost of a cube of hot and cold water. Perhaps it will cost it cheaper. As for the gas columns, usually the cost of gas is slightly lower than the cost of electricity, and therefore you can use water heated using a column.

By connecting the dishwasher to electricity, remember that the outlet should not be too close to the sink or pipes with water/gas, otherwise it can cause a short circuit and even fire.

Low.Power dishwashers

We have selected for you several models of economical dishwashers. Thanks to modern equipment, they are able to be content with a very small amount of electricity. At the same time, the quality of washing, of course, does not suffer at all. Here they are. High technologies.

What nodes and details affect energy consumption

Each dishwasher consists of a certain set of nodes and parts. All of them consume a certain amount of energy. The level of its consumption depends on the following components:

  • Ten. The most energy.Consuming element. The power of this device heating water for washing dishes fluctuates widely and may exceed 2 kW. Its operating time depends on the level of water temperature, which is set in the selected program. The temperature range is quite wide. From 30 35 ℃ to 70 80 ℃. PMM models with forced drying have another heater that raises the air temperature, as well as the fan. Unlike devices with convection drying, such dishes of energy costs more.
  • Circulation pump-pumps the liquid into the nozzles of the rod spray, and also ensures the re-use of water in order to save it. The power of this pump is small, approximately 100 watts. The longer the dishes laundering program lasts, the more energy consumes the device.
  • Drain pump. Pushes out the worked out liquid into the sewer. Pump power. From 30 to 40 watts. The duration of its work depends on the amount of dirty water, which must be removed from the PMM.

Drain and circulation pumps of the dishwasher (view from below)

Energy consumption indicators depend on several more factors:

  • The amount of liquid consumed for one washing cycle. The indicator ranges from 7-15 liters. The more water, the longer it needs to be warm. The operating time of the drain pump also depends on the volume of water.
  • Duration of the washing process. Time depends on the program selected by the user and fluctuates in a wide range. From 40 minutes to 4 hours. This indicator affects the general energy consumption of circulation pump.
  • The size of the basket. This indicator determines the amount of the dining room of the utensils, which can be washed in one cycle, and affects all the rest. If we compare narrow and full.Sized PMM, then the latter will need more water, as well as more powerful electric heater and pump for sprayers. The smallest energy consumption and power have nodes of small desktop vessels.

Power of the dishwasher: how much it consumes, in kW, bosch, energy consumption, which

When choosing a dishwasher, attention should be paid to the power indicator. It can vary from 0.4 kW to 2.7 kW. Modern equipment is available with a minimum energy consumption indicator, on average it is 0.7 kW. The power of the dishwasher depends on the size of the water tank, the amount of heated liquid, such as drying and many other moments.

What the indicator depends on

The modern dishwasher is represented by a combination of devices that consume electrical energy. The main elements can be called:

  • Thermal heater. The dishwasher during operation conducts water heating to increase the efficiency of washing. The main power consumer can have a capacity of 2.8 kW. The energy consumption largely depends on the temperature of the water heating, the maximum indicator is 65 ° C. Therefore, to reduce energy consumption, it is recommended to choose a more suitable heating temperature.
  • Pressure pump in the system. This element in most cases has a capacity of 100 watts. To increase efficiency when washing dishes, water is supplied under pressure. The duration of the washing cycle depends on how much energy will be used to power the pump.
  • Water pump. The energy consumption of dishwashers is associated with water removal. The power of this element reaches 25-30 watts. The device periodically pumps out dirty water.

In addition to standard details, the technique in question has additional components that consume a small amount of energy.

The power of the dishwasher in the KW is indicated by almost all manufacturers. The above information determines that such an indicator is curled from such factors:

What is a kilowatt hour? Understanding home energy use

  • The volume of water used. Most programs are designed to use 7-15 liters. Less energy goes to heating a smaller amount of liquid.
  • The duration of the selected cycle. Depending on the program, the sink can be diverted from 40 to 260 minutes. For the entire period, the installed pump pumps water to supply it under pressure.

The dishwasher consumes less energy when choosing an economical regime.

Energy efficiency classes

The power consumption of the dishwasher (kilowatts) is divided into 7 groups that simplify the choice of the most suitable equipment. Latin letters are used to designate:

  • BUT. This assessment is the highest, it means consumption of a low amount of electricity. On average, the indicator is 0.7-1.05 kW. The appearance of modern equipment led to the use of class A and A, the power of which is 0.6 and 0.4 kW, respectively.
  • AT. Equipment with such an assessment has a indicator of 1.07-1.1 kW.
  • With. In the manufacture of dishwashers, components can be used, the total power of which is 1.1-1.5 kW.
  • D and e. This class is an average assessment, since the power consumption is 1.5-2.3 kW.
  • F and g. The lowest rating of energy consumption determines that the power of the dishwasher is more than 2.7 kW. This category includes exclusively old models.

It is recommended to purchase class A and A models. The cost of electricity is constantly growing, a low consumption indicator allows you to reduce costs. Despite the low power, dishwashers cope with the tasks.

All dishwashers are conditionally divided into 3 main classes:

  • Basic models. They have a minimum set of programs, noise at 50 dB.
  • Functional devices. For effective cleaning dishes, the equipment is equipped with a considerable number of programs.
  • Advanced. Only expensive models have a large set of programs. Over, some are associated with the analysis of water stiffness and other moments.

Modern models can do more operations for the cycle, while spending fewer energy. A lot depends on the flow rate, too high power can lead to overheating of the wiring.

How to make more economically

You can reduce the amount of electricity consumed in several ways. The most common are the following:

  • Choosing a program with a launch program. Some models have dishes of half a half loading. Its use allows you to reduce water and energy costs by 30%.
  • Using equipment with heat exchanger. A similar technology reduces expenses by 20%.
  • Conducting periodic maintenance of household equipment provides for the cleaning of the heating element from scale. The thick layer of mineral deposits can significantly reduce the efficiency of heating. The use of special filters to reduce water hardness also solves the problem with the formation of scale. Long.Term use with a scale on a heating element can lead to its wear and failure. At the same time, the repair will be expensive, it is difficult to carry out it independently.
  • It is recommended to leave the sink of dishes at night. Due to this, filling out.
  • For washing, slightly contaminated dishes, it is recommended to choose economical modes. They use a small amount of water and conduct heating to less high temperatures.

In addition, it is not recommended to leave dirty dishes for a long period, since dried food residues when cleaning require more energy.

The most economical models

There are a large number of dishwashers on sale, which have a small indicator of energy consumption. The most popular are:

Which manufacturer is used at home?

Water consumption

The water consumption of the dishwasher varies depending on the brand and year of release. The general rule is observed: the more expensive the dishwasher, the less it consumes. No matter how simple and old the car is, its consumption rarely exceeds 20 liters. Modern devices are not even in economical mode consumes no more than 10 liters.

Consumption depends on the program, power of the dishwasher and the degree of pollution of the dishes. In order to prevent overspending, it is enough to soak dishes with dried.Up or burned food residues. After that, she easily copes with them even on an economical mode.

Suppose you need to wash 10 sets of dishes. Theoretically, you can calculate that about 2 liters flows from the tap for a minute. Water. Even the most skilled hostesses will take at least 10 minutes for so many dishes, and this is at least 20 liters, which significantly exceeds the consumption of the machine.
