All about washing machines

Washing machine power - how many kW does it consume?

Washing machine power in kWThe power of the machine can be different. And in order to determine the amount of kW that your household appliances use, you can familiarize yourself with the sticker. The one that is on her body. The label may indicate this information. You can also recognize her by specifying which energy class washing machines applies your model. Let's discuss this issue in more detail.

Power Consumption Classes

According to the efficiency in the consumption of electricity, all washing machines are divided into classes. Those classes that are more economical have a designation in the form of the Latin letter "A". Also, a + sign (s) can be added to it. These signs will inform us of even more modest consumption. The highest and most economical designation is "A ++". The most economical - "G".

Typically, badges that indicate the class of household appliances, whether it is a refrigerator, a washing machine, or other large units, are placed on stickers. Those that are placed on the case. You can also find them in the detailed description of your machine on the manufacturer’s website.

The amount of kW / h per kilogram of laundry to be washed is calculated under laboratory conditions. After which there is an assignment to various models of household appliances of one or another class of energy consumption.

How many kW per hour do different classes of washing machines use?

  • Let's start with the most economical option. Class A ++ needs the smallest amount of energy. Such machines need less than 0.15 kW / h per kilogram of laundry.
  • What follows is “A +”. A washing unit with this marking will need less than 0.17 kW / h per 1 kg of clothes to be washed.
  • The letter “A” means that the consumption of electric power will be in the range from 0.17 to 0.19 kW / h per kg of laundry.
  • For a machine with the designation "B", 0.19-0.23 kW / h / kg will be needed.
  • For class “C”, 0.23 to 0.27 kW / h per kg of laundry will be sufficient.
  • A machine marked “D” will require 0.27 to 0.31 kW / h per kg of items.
  • The remaining options are listed in detail, it makes no sense. Since modern household washing machines do not use them. We can only mention that they will require more than 0.31 kW / h / kg.

For laboratory tests, it is customary to use washing at 60 degrees. And the clothes of their cotton are used as laundry. The drum is loaded with the maximum permitted amount of laundry. All calculations that lead to the determination of the class of energy efficiency come from such a wash.

As you know, a different amount of kW can be used in real washing. Since things may be made of another material, the temperature and washing conditions may also be different.

What else can affect the number of kilowatts consumed by the machine?

It should also be noted that the following factors also affect the actual amount of energy consumed. And more specifically:

  1. The program selected for washing clothes. It can differ in heating temperature, duration, intensity, the number of engine revolutions during spin cycle, the presence / absence of additional options (for example, adding a second rinse), etc.
  2. The type of fabric from which the clothes to be erased is also important. Since different fabric may have different weight in dry and wet state. In addition, it may require different washing modes.
  3. In addition to the above, it can affect the number of kW and how loaded the drum of the washing machine is.

How much electricity is needed for other household appliances?

Next, we present a table that has average power consumption values ​​of various household electrical appliances that can be used at home.

Type of appliance Power consumption
Hob From 1 to 2 kW.
Cooker hood From 0.12 to 0.24 kW.
Water heater up to 150 liters It is approximately equal to 6 kW.
Air conditioning household 0.4 - 0.24 kW.
Microwave 0.6 - 2kW.
Mixer About 0.2kW.
Vacuum cleaner home Approximately 1kW.
Tumble dryer 2-3kW.
Stationary computer 0.3-1kW.
Dishwasher About 3kW.
Normal TV 0.15kW.
Iron 1kW.
Fridge 0.2kW.
Electric stove 3-8kw.
Electric grill 1-3.6kW.
Toaster 0.8-1.5kW.
Pressure cooker From 1 to 2 kW.
Built-in oven From 2 to 5 kW.
Coffee machine From 0.5 to 1 kW.
Instantaneous water heater About 3.5kW.
Freezer About 0.2kW.

    Electricity is not measured in kW / h, but in kW * h.

  2. Gravatar Artem Artyom:

    Power in class is not what is written in the article. In this case, it is described how many kilowatts the washing machine will twist on an electricity meter, multiplying which by the amount of the tariff you will find out how much in monetary terms you will spend per hour of washing. The very same washing power on average is from 1.5 to 2 kW. Let's say the heating element is from 1.2 kW, the pump is about 24 to 0.5 kW, and the engine is a rotating drum. We summarize all this and get the power at which you can calculate the cross section of the wire and the circuit breaker in the shield. And class A, A ++, etc. is the average number of kW spent on washing at 60 °.
