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; surely less resources are spent with manual washing? In the article, we will analyze which of this is true, what is the water consumption in the dishwasher, how profitable it is to use home PMM.
How much does a dishwasher use
How much PMM uses in one wash depends on the type, class, load. The manufacturer indicates this data in the technical specifications. So:
- Compact models can hold 6-8 sets of dishes. For one cycle take about 7-10 liters.
- Full-sized and narrow appliances with a capacity of 10 to 14 sets consume from 9 to 14 liters.
- Professional dishwashers that are used in 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 you will have to save up dirty dishes 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 displacement 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 the machine consumes per cycle, and how much it takes to manually wash appliances. At the same time, keep an eye on the cold water meter, because most PMMs are connected to a cold tap (read the article about 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 in order to reach 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 in one cycle. Whereas 43 liters were spent for washing tableware by hand in such an amount (the total consumption from the hot and cold faucet is taken into account; the faucet was blocked during soaping of the plates). Savings are evident.
Why does this happen? The secret of savings in the principle of operation 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, the nozzles release jets under high pressure, which allows you to effectively wash appliances, and spend a little. Thanks to electronic control, the sensor will not allow you to use more than necessary.
Is there a savings or not? For one year of using the equipment, 8280 liters of water are consumed, which is beneficial, even taking into account the economical consumption of resources during manual washing. 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.
Users will notice that washing also requires electricity and detergents. All this applies to manual care, and there is much more free time.
You have learned how many liters the dishwasher takes and whether it allows you to save. When choosing, pay attention to the class of the model, calculations must be carried out individually. But keep in mind the undeniable fact – this is a significant time saver.
