If you pay attention to the power of the dishwasher when choosing, you can save.
Tariffs are rising every year, utility bills are growing, so buyers are interested in purchasing low-power equipment. They also pay for a large number of household appliances: a dishwasher has been added to the washing machine, refrigerator, water heater, air conditioner.
Why do some cars save money and others don’t?
The efficiency of an electrical appliance depends on the energy efficiency and functionality of a particular model. The maximum consumption of the heating element, circulation pump and pump. But the main electricity consumed by the dishwasher falls on the water heater, the second in terms of consumption is the heating element, which provides drying. In models that do not provide for hot drying, energy is spent more economically.
Important! Users are interested in what is more economical: use a dishwasher or wash by hand? 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’re looking for a machine that cleans well and uses less resources, consider the convection dryer option, which uses up to 40% less energy.
Electricity consumption depends on the volume of the tank and the degree of water heating. 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, cars from the concern Bosch (and Honey and others) provide in their design heat exchanger. 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 a Latin letter. Judge by the letter how much PMM will consume in Watts:
- А — 0,7-1,07 kW;
- В — 1,08-1,1 kW;
- С – this class of energy consumption assumes a consumption of 1,5 kW;
- D и E – rare values u2buXNUMXbthat can be found in older dishwashers, equal to consumption up to XNUMX kW;
- F и G – energy classes, indicating costs of 2,5 and 2,7 kW, respectively.
When the manufacturer manages to bring the PMM design to a flow rate of less than 0,7 kW, a “+” sign is added to the letter A on the marking. Today there are such highest classes: A +, A ++ и A+++. They talk about the significant cost-effectiveness of the device – these are the best options on the market.
How to increase the profitability of PMM
In order to reduce the power consumption of the machine, this must be taken care of even before purchasing a dishwasher. This does not mean that you need to look for a model by calculating each watt. Just heed the advice of the experts:
- Use delayed start function. First, start the program and wait until the pump fills the tanks with water, then turn on the delay by calculating the time so that the machine works at night. This is relevant for those users who pay bills at differentiated rates (cheaper at night). The second trick is that during the time that the water is in the tanks, it will warm up to room temperature, and the heater will be less involved.
- Do not hoard dishes and do not let them dry out. When you load a dish with dried food into the hopper, the technique spends more energy to wash it all: you need to heat the water more, add a rinse, etc.
- If you have not yet bought a machine or are thinking about purchasing a new model, pay attention to options equipped with a heat exchanger. You can learn more about this PMM node from the review “What is a heat exchanger in a dishwasher».
- Pick up suitable wash cycles. Do not thoughtlessly turn on the first program that comes across: proceed from the degree of contamination of the dishes. If the plates are “fresh”, it is enough to wash them on a short cycle at 30 degrees – this will provide a decent savings.
- Use half (partial) loading of the bunker with a small amount of dishes. To avoid excessive foaming and leaks, as well as streaks on dishes, strictly dose detergents.
Important! The new PMM models have economical programs such as “Economy” or “Express” washing, which either do not last long or lower the water temperature and cut down the washing time. Also in Bosch machines there is an option Vario Speed or Vario Speed Plus, which reduces washing and drying by almost half without loss of quality.
- Do not wash 3 plates – collect enough dishes For loading. So that it does not dry out, put the plates and cups directly into the washing tank.
- Arrange dishes in baskets according to the rules – then it will be better washed off and will not have to be washed. Detailed information on this topic is waiting for you on the page “How to load dishes in the dishwasher».
- Do not forget clean scale in PMM. A heater, overgrown with limescale, consumes many times more energy during heating than a clean heater. Take a look at the reviewHow to descale a dishwasher» and find the right cleaner for 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 savings. At the same time, too low power may not meet expectations – in exchange for savings, you will have to sacrifice the quality of washing: such a PMM can heat water for a long time, cope only with a small amount of dishes, etc.
Therefore, the ideal solution is a model with medium power, but maximum efficiency. Consider the most successful models in our opinion.
ZIGMUND & SHTAIN DW 69.6009 X
This is a full-sized built-in electric dishwasher, designed for 15 dishes and equipped with a turbo-dryer. The Turkish-made model breaks all records – with an A ++ energy efficiency class, the machine consumes up to 0,5 kW. Savings plus: 3 versions of the half-load function. There is also an “Express Program” (Fast Cycle) and an “Economy Mode”.
The cost on the official website of the company (Russian version) is 35 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 hopper holds up to 14 sets of dishes, and the energy efficiency class corresponds to the A +++ mark: 0,4 kW or 0,83 kW / h. The functionality provides for 8 washing modes, among which there are also “Express” and “Economic” cycles. Half load done. 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 at 37 rubles.
TEKA DW8 41 FI
Another PMM from the middle price category (31 rubles) from a German brand. With class A++, it consumes 000 kW (or 0,5 kWh) and provides maximum efficiency not only in terms of electricity, but also water and detergents. This model can rightly be given the primacy of our rating, calling it economical in all respects. It provides for a start delay of up to 0,75 hours, among the 24 programs there are both economical and fast cycles.
Also, TEKA DW8 41 FI saves usable space in your kitchen, as it is a narrow model with dimensions of 45x55x82 cm (WxDxH).
Fact! This model from TEKA consumes up to 9 liters of water per wash cycle, while using up to half of the standard required amount 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 energy consumption class. By choosing a car with a class from A to A +++, you will save on utility bills. Good luck and easy savings!
