If you pay attention to the power of the dishwasher when choosing, you can save.
Tariffs increase annually, utility bills are rising, so buyers are interested in acquiring low-power equipment. They also pay for a large number of household appliances: a dishwasher was added to the washing machine, refrigerator, water heater, air conditioning.
Why do some cars save, while others do not?
The efficiency of an electrical appliance depends on the energy efficiency and functionality of a single model. The maximum consumption of the heater, circulation pump and pump. But the main energy consumed by the dishwasher is accounted for by the water heater, the second most consumed is the heater, which provides drying. In models in which hot drying is not provided, energy is spent more economically.
Important! Users are interested in what is more economical: use a dishwasher or wash with hands? Electricity costs can be equal if you use a boiler to heat water. As for water consumption, with PMM you can save tens of liters daily.
If you need a machine that will clean and consume little resources efficiently, pay attention to the option with convection drying - they require 40% less electricity.
Electricity consumption depends on the volume of the tank and the degree of heating of the water. The smaller the tank, the less water is used for washing - and you need to pay less.
Also, cost reduction is possible when choosing models with innovative economy solutions. So, machines from the Bosch concern (as well as Miele and others) include a heat exchanger in their design. It saves thermal energy, and the device becomes as economical as possible.
Before you buy a dishwasher, you should find out its energy efficiency. This is easy to understand by the simplest characteristics of the machine - look at the special information sticker indicating the class indicated by the Latin letter. Judge by the letter how much PMM will consume in Watts:
- AND - 0.7-1.07 kW;
- IN - 1.08-1.1 kW;
- FROM - this class of energy consumption requires a consumption of 1.5 kW;
- Dand E - rare values that can be found in older dishwashers, equal to consumption up to 2 kW;
- F and G - energy consumption classes, indicating costs of 2.5 and 2.7 kW, respectively.
When the manufacturer manages to bring the PMM design to a consumption of less than 0.7 kW, the “+” sign is added to the letter A on the marking. Today there are such highest classes: A +, A ++ and A +++. They talk about the significant cost-effectiveness of the device - these are the best options from those on the market.
How to increase the profitability of PMM
To reduce the power consumption of the machine, care must be taken before purchasing a dishwasher. This does not mean that you need to look for a model, calculating each Watt. Just follow expert advice:
- Use delayed start function. First, run the program and wait until the pump fills the tanks with water, then turn on the delay, calculating the time so that the machine will work at night. This is true for those users who pay bills at differentiated rates (cheaper at night). The second trick is that while the water is in the tanks, it will warm up to room temperature, and the heater will be used less.
- Do not store dishes and do not let it dry. When you load dishes with dried food into the hopper, the appliance spends more energy to wash all this: you need to warm up the water more strongly, add rinse, etc.
- If you have not bought a car or are thinking about purchasing a new model, pay attention to heat exchanger options. You can learn more about this PMM unit from the overview “What is a heat exchanger in a dishwasher”.
- Pick up suitable washing cycles. You should not thoughtlessly include the first program you get: proceed from the degree of contamination of the dishes. If the dishes are “fresh”, just wash them on a short cycle at a 30-degree temperature - this will provide decent savings.
- Use half (partial) hopper loading with a small amount of dishes. To avoid excessive foaming and leaks, as well as stains on dishes, strictly dose detergents.
Important! The new PMM models provide cost-effective programs, such as “Economy” or “Express” washing, which either last for a short time or reduce the temperature of the water and shorten the washing time. Bosch machines also have the Vario Speed or Vario Speed Plus option, which reduces washing and drying by almost half without loss of quality.
- Do not wash 3 plates each - collect enough dishes For loading. So that it does not dry out, put the plates and cups immediately in the washing tank.
- Lay the dishes in baskets, according to the rules - then it’s better to wash off and do not have to wash. Detailed information on this subject is waiting for you on the page "How to load dishes in the dishwasher."
- Do not forget clean scale in PMM. TEN, overgrown with limescale, when heated, consumes many times more energy than a clean heater. Take a look at the “How to descale your dishwasher” overview and find the right detergent for cleaning the hopper and machine parts.
Which PMM is the most economical
Power is not only a plus for functionality and performance, but also a huge minus when it comes to saving. At the same time, too low power may not meet expectations - in exchange for savings, you will have to sacrifice the quality of the sink: such a PMM can warm water for a long time, cope only with a small volume of dishes, etc.
Therefore, the ideal solution is a model with average power, but maximum efficiency. Consider the most successful models in our opinion.
ZIGMUND & SHTAIN DW 69.6009 X
This is a full-size built-in electric dishwasher, designed for 15 cookware sets and equipped with a turbo-dryer. The Turkish-made model breaks all records - with the energy efficiency class A ++, the car consumes up to 0.5 kW. Plus to profitability: availability of half load function in 3 options. There is also an "Express program" (Fast cycle) and "Economy mode".
The cost on the official website of the company (Russian version) is 35,799 rubles, which is not bad at all with its impressive characteristics.
Flavia BI 60 KAMAYA
The previous model was bypassed by an Italian-made machine. The bunker holds up to 14 sets of utensils, and the energy efficiency class corresponds to A +++ mark: 0.4 kW or 0.83 kW / h. The functional provides 8 washing modes, among which there is also an “Express” and an “Economic” cycle. Half load implemented. It also has an Express Wash option: by pressing this button, you reduce the duration of any program by 30%.
The cost, according to YandexMarket, starts from 37 087 rubles.
TEKA DW8 41 FI
Another PMM from the middle price category (31,000 rubles) from the German brand. In class A ++, it consumes 0.5 kW (or 0.75 kW / h) and provides maximum efficiency not only in terms of electricity, but also water and detergents. This model can rightfully be given the primacy of our rating, calling it economical in all respects. It provides a delay in launch up to 24 hours, among 9 programs there is both an economical and a quick cycle.
Also TEKA DW8 41 FI saves usable space in your kitchen, as it is a narrow model - with dimensions 45x55x82 cm (WxDxH).
Fact! The indicated TEKA model consumes up to 9 liters of water per wash cycle, using up to half of the standard required volume of salt, detergent and rinse aid.
So, the resource consumption of each individual model does not depend on the characteristics or features of the connection, but on the class of energy consumption. Having picked up a car with a class from A to A +++, you will save on utility bills. Good choice and easy savings!
