Dishwasher power

Modern household equipment is selected based on some of the characteristics that users pay attention to. Choosing a dishwasher most often begins with determining the required power, as well as the energy consumption indicator. What determines the power of the dishwasher, we will consider in the article.

The complex structure of a modern type dishwasher includes certain elements that affect the performance indicators.

1. Heaters. Thermal heaters are essential to improve the efficiency of your dishwasher. They heat water to a certain temperature. The heater has the characteristics of the main energy consumer. The power of the thermal heater can be 2.8 kW and will depend on the set water temperature at which the work is carried out. The maximum heating rate of the water temperature can reach 65 degrees.

2. Pressure pump. The power of this equipment is most often 100 watts. This element is necessary for the supply of pressurized water when washing dishes, which makes the whole process more efficient. The energy consumed by this element will directly depend on the length of the cycle of the washing process.

3. The pump used to drain the water. The power of the dishwasher will be influenced by the details of the water removal process. The drain pump consumes 25 to 30 watts.

This list includes standard components, without which no dishwasher can work.

Each manufacturer strives to indicate the capacity of the dishwasher equipment in kilowatts.

This characteristic will be influenced by 2 main factors.

• The amount of water used. On average, the program consumes from 7 to 15 liters. The use of a reduced volume of water contributes to lower energy consumption.

• Washing cycle length. The dishwasher can be operated for 40-260 minutes. During this time, the pump pumps water and supplies it under pressure.

Many users are interested in what average energy consumption is set for dishwashers. Knowledge of these characteristics helps to determine the choice of a future model. The options with average performance include class A + or A ++ dishwashers. In such equipment, the consumption of kilowatts per wash will be from 0.4 to 0.6 kilowatts per hour. This characteristic will be influenced by the temperature of water heating and the duration of the process. Based on the number of washes, you can calculate the amount of energy consumed per month when the machine is running.

In order to make it convenient for users to choose equipment for washing dishes, a classification was approved, dividing dishwashers into 7 classes, which are indicated by a Latin letter.

This group includes equipment that is characterized by a low amount of energy consumption. The average characteristic is from 0.7 to 1.05 kW. In this class, there are advanced models in which the maximum power consumption is allocated at the level of 0.6 and 0.4 kW. Such models are assigned class A + and A ++, respectively.

In equipment belonging to this group, the power indicator will be from 1.07 to 1.1 kilowatts.

In the dishwasher of this group, parts are used, the operation of which requires a power consumption in the range of 1.1-1.5 kW.

This group includes equipment that has an average rating for power consumption. The nominal figure will vary from 1.5 to 2.3 kilowatts.

The last group has the lowest energy consumption rating. The capacity of such equipment will exceed 2.7 kilowatts. This is the characteristic of older dishwashers, which consume a lot of energy.

When choosing the most suitable group of dishwashers for home use, you should pay attention to classes A + and A ++. Models belonging to these groups have optimal power ratings. Due to the high cost of electricity, this characteristic will be very important, since it will reduce the cost of utilities. Energy consumption indicators do not affect the quality of the solution to the tasks set for the dishwasher.

In addition to this classification, dishwashers can be divided into several more groups.

• Standard models. They differ in the minimum set of programs with which you can wash dishes. The noise of such equipment does not exceed 50 dB.

• Functional models. The number of programs used for cleansing is much wider than in standard versions.

• Advanced models. This most often includes equipment that has a high cost associated with a large set of programs. In such models, the analysis of water hardness and other characteristics necessary for the stable operation of equipment is carried out.

Modern models of dishwashers are capable of performing a large number of operations in one wash cycle with minimal energy consumption. The characteristic of the power consumption determines not only the functionality of the equipment, but also the load that it bears on the power grid.

Many users prefer economical dishwashers, but are still looking for a way to further reduce their electricity consumption.

To save energy, you should use the recommendations of specialists.

• Use half load mode. Its application is characterized by a reduction in water and energy costs by up to 30%.

• Use of equipment where the heat exchanger is installed. This will reduce costs by up to 20%.

• Periodically service the household dishwasher. Such activities include cleaning parts from the scale that has appeared. Mineral deposits, which are deposited in a thick layer on the parts, affect their operation, and also reduce the efficiency of the heating elements. This also includes recommendations for using a filter that allows you to reduce the hardness of the water, thereby solving the problem associated with the occurrence of scale. The presence of such deposits on the heating element often leads to its wear and tear. Such repairs are always expensive and carried out only by specialists.

• If you need to wash not too dirty dishes, you should use economy modes, since they consume a small amount of liquid and heat water to low temperatures.

• To save energy, you should pay attention to the option of connecting the dishwasher directly to the system that supplies hot water to the house. This can help save a significant amount of electricity, since the main expense is spent on heating the water. In addition, the dishwasher analyzes the temperature that enters the equipment and compares it with the set temperature in the program. If there is a difference between these characteristics, heating is switched on.

• When using a boiler as a source of hot water in a home, it is worth conducting a thorough analysis of the capacities of the boiler equipment and the dishwasher. If the boiler has a much higher energy consumption, the use of a hot water connection in this case will be irrational.

• If the machine is installed in an apartment with hot water supply, it is necessary to analyze the cost of hot and cold water per 1 cubic meter. Often, users note that heating water in a dishwasher is much more profitable than connecting directly to a hot water supply.

• If hot water in the apartment is supplied using a gas water heater, it is worth considering the low cost of the gas resource. In this case, you can directly connect the dishwasher to hot water and reduce the amount of energy consumed.
