A dishwashing machine frees up time and hands, but housewives still doubt its efficiency. Why do we need equipment that additionally consumes electricity and water; Could it be that less manual resources are spent on manual washing? In the article we will analyze what is true of this, what is the water consumption in the dishwasher, how profitable it is to use home-made PMM.
How many resources does a dishwasher spend
How much PMM is used in one wash depends on the type, class, load. The manufacturer indicates these data in the technical specifications. So:
- Compact models hold 6-8 sets of dishes. For one cycle, take about 7-10 liters.
- Full-size and narrow devices with a capacity of 10 to 14 sets consume from 9 to 14 liters.
- Professional dishwashers, which are used in public catering, use up to 25 liters.
The technique is selected taking into account the number of people. Do you have a small family? Buy a compact version, otherwise it will take a long time to accumulate dirty plates for a full load.
Note! In modern brands - Bosch, Siemens, Milli - there is a half load function. At the same time, resource consumption is halved.
In some models, the consumed volume is more than indicated in the instructions.
Does the dishwasher save water
If you have meters in your apartment, you can compare how much water a machine spends per cycle and how much it takes when washing appliances manually. At the same time, keep an eye on the cold water meter, because most PMMs are connected to a cold tap (read the article on connecting a dishwasher).
Hot water contains a large amount of impurities. You will have to install an additional filter, as well as constantly mix it with a cold stream to achieve the optimum temperature.
To independently compare how much is spent on manual washing and during the use of equipment, consider: how many sets fit in your PMM.
Take, for example, 14 sets - this is 34 devices. According to the manufacturer, a narrow PMM uses 10 liters per cycle. Whereas for washing dishes with hands in such an amount 43 liters were spent (the total consumption from the hot and cold tap is taken into account; during soaping the tap was blocked). Saving is obvious.
Why does this happen? The secret to saving is the principle of the PMM. Many Bosch brand models, for example, are equipped with a water flow sensor. It is passed through a filter and can be applied several times. In addition, nozzles blow jets under high pressure, which allows you to efficiently wash devices, and spend a little. Thanks to electronic control, the sensor will not allow you to use more than necessary.
Is there a saving or not? For one year of using the equipment, 8280 liters of water are consumed, which is profitable, even considering the economical consumption of resources during a manual wash. If you spend more than 100 per day, then the savings will be even greater.
Benefits of Using a Dishwasher
During the operation of the equipment only cold water is consumed, the tariffs for which are much lower. Each device is equipped with a heating element for heating.
Users will notice that washing also requires electricity and detergent powders. All this applies with manual care, and much more free time.
You have learned how many liters a dishwasher takes and whether it saves. When choosing, pay attention to the class of the model, the calculations must be carried out individually. But consider the indisputable fact - this is a significant time saver.
