When choosing a washing machine, the user looks not only at the number of functions, but also at the energy efficiency class. It is important that the equipment does a good wash and at the same time consumes the minimum amount of energy. In this article we will tell you how to determine how much energy a washing machine spends.
What are classes for and how to define them
The power of any device can be determined by the number of indicated watts. But for a simple user it can be difficult to navigate in numbers. Therefore, manufacturers have simplified the task by creating classes of electricity consumption. Given the amount of energy consumed, the washing machine is indicated by a Latin letter. The energy consumption table below shows the class, as well as how much energy the machine will cost in one hour when loading one kilogram of things.
Marking | Value |
SMA with energy class A ++ the most economical of all machines today. | For washing 1 kg of laundry, the machine will use up only 0.15 kW / h. |
Class is considered less economical A +. | If you choose this washing machine, it will process a kilogram of laundry, consuming less than 0.17 kW / h. |
Class Labeled Machines AND . | In this case, a little more resources are spent - 0.17-0.19 kW per hour per kilogram of things. |
Energy class IN . | The consumption of such SM is from 0.19 to 0.23 kW per hour. |
Energy efficiency class FROM . | To process one kilogram of linen per hour, 0.23-0.27 kW is required. |
Energy class washer D . | The energy consumption will be 0.27-0.31 kW / h. |
Marked wash E . | Normal consumption will be 0.31-0.35 kW per hour. |
Class F . | When washing a kilogram of things, 0.35-0.39 kW per hour will be used. |
The most "wasteful" car with a class G . | Consumption will be more than 0.39 kW per hour. |
It's important to know! Tests to determine energy saving classes were carried out in special conditions. Indications may increase depending on the selected mode.
How did the energy classification come about?
Even 20 years ago, buyers began to pay attention to how economical the machine is in operation, and not just on a set of functional qualities. Even then, machines began to indicate energy efficiency information. However, in different countries the indications were different. Therefore, in 1992, officially in the EU, a single classification with Latin letters was created. Now it is used all over the world, marking the housing of the washing machine with special stickers.
What can affect energy performance?
- Mode selection. A program with a long wash cycle and high water temperature can increase electricity costs.
- Overload. The calculations in the table are based on one kilogram of laundry. Due to the large load, consumption increases. This also applies to the type of fabric, which when wet can become heavier than the norm.
- Care and life. Over time, scale forms on the heater, which does not allow the heating element to transfer heat normally. The result is increased electricity consumption. Caring for the heating element will help avoid future costs and breakdowns.
These factors affect energy consumption. You will not be able to accurately calculate expenses yourself. Therefore, when buying, pay attention to the marking of the washing machine. A video on the topic will help you:
