Dishwasher power

The market may surprise the consumer with an abundance of various dishwashers. All models have different dimensions, design, characteristics. One of the determining factors is the power consumption of the dishwasher, measured in kW / h. In most household appliances, increased power is a sign of the high efficiency of the device, but in the case of dishwashers, it, on the contrary, looks like a serious drawback. Low-power dishwashers help reduce power consumption, so these devices are in high demand.

What determines the power rating

The capacity of the dishwasher depends largely on the cost of electricity for the operation of the component units. Most consumes electricity, of course, heating heater, the second place is occupied by the heating element, which ensures the drying of dishes.

In dishwashers that do not use hot dryers, the amount of electricity consumed is much lower.

Energy costs of cars are in direct proportion to water tank volume and water temperatures. Deciding how much dishwasher to choose, lies in the plane of how many family members use it. Reduce energy consumption and various new technical solutions. For example, the company Bosch applies the installation efficient heat exchangerswhich save energy of heat, and accordingly reduce an expense of the electric power.

The letters denoting the class of the dishwasher sufficiently well characterize the power expended.

1. Class A, B and C dishwashers have the best rating, their power consumption does not exceed 1.5 kW.
2. Models classified as E and D have average characteristics.
3. Class F and G are obsolete types of machines that consume very high power for this class of devices - up to 2.7 kW.
4. There are also unique class A + cars on the market; in the “economical wash” cycle, they take no more than 0.63 kW.

The struggle to save electricity

A significant part of the electricity consumed for heating water. You can often find recommendations to connect the machine directly to the hot water system in the house. After all, the dishwasher analyzes the temperature of the incoming water and compares it with the set one, if there is a difference, it turns on the heat. How effective is this saving? This is due to the origin of hot water in a particular dwelling.

1. If hot water gives boilerit is reasonable to compare its power with the power of heating water in the dishwasher. If the boiler consumes less power, there is every reason to use its hot water.
2. If you live in a standard house with hot water supply, it is necessary to compare the cost of a cubic meter of hot and cold water. It often happens that it is cheaper to heat cold water in a dishwasher than to connect hot water.
3. If the apartment is installed gas water heater, taking into account the low cost of gas, it makes sense to use the water heated in the column.

Useful tips

In order for the dishwasher to spend less electricity, and at the same time remain efficient, it is advisable to listen to the following recommendations:

1. Dishes cleaned with delayed launch. Turn on the machine until the water tank is completely filled with water and suspend the execution of the program so that the machine will restart at night. On the one hand, in a few hours the water in the tank will warm up to room temperature and it will have to be heated less, on the other hand, the nightly tariff for electricity is much less.
2. Do not accumulate heavily soiled dishes. Leftover food debris on the plates will require a lot of energy to clean up the dishes. You will need very hot water and double rinse. All this is very energy intensive.
3. As mentioned above, it is better to purchase cars with built-in heat exchanger.
4. It is necessary to select the most optimal modes of washing dishes. If the dishes are not very dirty, you can turn on the sink with a temperature of 30 ° C and use the shortest program in time.
5. In advanced models there are profitable option modes, such as "accelerated washing". The whole wash cycle is placed in 30 minutes. The disadvantage of such devices is their small capacity dishes. Use such dishwashers can a small family of 4 people.

It should be borne in mind that new technologies are rapidly promoting the process, and new types of machines are emerging on the market that work more efficiently and with small energy resources.
