Why does the washing machine overheat water and boil it during washing

Expert answers

Elena:

The dishwasher can be connected to both cold and hot water mains. Most appliances are connected to a "cold" pipe, because, from the point of view of manufacturers, this is better for both the machine and the dishes: cold tap water is cleaner than hot water. On the other hand, connecting the machine to a hot water pipe does not waste time and electricity for heating the volume of water necessary for washing, therefore, some companies produce dishwashers with such a possibility of water, provided that the maximum water temperature is not higher than 60 ° C. You can choose a compromise option - a dishwasher connected through a mixer. In this case, you can choose between clean cold water or economical hot water. For such work, for example, special mixers from Swedish manufacturers are adapted. I have it connected to cold water.

Lexsa:

only cold.

Knowing of limits:

Only cold, it warms up there

gjknrr:

Cold and hot..

Anyutka:

In general, only cold, but there are machines with the ability to connect to hot water.

Perova Olesya:

only cold

MARGOSH:

cold only. like a washer.

White Hare:

most of the equipment is connected to a cold pipe for a different reason - because in the west centralized hot water supply is rare, and economically it’s all the same to heat water in a boiler or in a typewriter, but technically it’s more convenient in a typewriter, but we have hot water “free” as a rule, a filament filter can be placed on hot water in front of the entrance to the machine, which will collect all rust and other debris

Julia Mironova:

Most machines are connected to a cold water line: manufacturers believe that this is better for both the machine and the dishes. Cold tap water is actually cleaner than hot water. But you have to spend time and energy on heating the volume of water necessary for washing. Therefore, some companies, among which, for example, Electrolux, produce dishwashers with the ability to connect to a hot water main, provided that its temperature does not exceed 60 ° C.

Taiga:

The dishwasher is connected to cold water, it itself heats the water to the desired temperature. If you connect to a hot one, the program may crash. And it won't be a cheap repair.

HE:

there will be no crash in the program! Less electricity will be spent. The dishes are not clothes, and therefore it is quite possible to use hot water.

Vereshchagin:

... quite ... for some of them they have been connected to hot water for many years and work ... statistics ...

Calculation of electricity consumption for washing

In order to calculate the energy consumption, you must first find out how much time it takes to heat the water. I dug around on the Internet and found in one section “Calculations for the home” that: “in everyday life, you can use an adapted empirical formula, according to which the time t (in hours) required to completely heat the water in the tank of the storage water heater (and the washing machine is also a kind of tank) is defined as follows":

where V is the volume of the tank (l), for our case it will be 15.5 liters; T2 is the temperature of the heated water (we take approximately the average 60°C); T1 - the initial temperature of cold water, in the water supply it is usually about 8 ° C; W is the electric power of the heating element (kW), in Bosch it is written: 2.2-2.4 (kW), let's take the average 2.3. We substitute:

Note that 0.41 hours is almost 25 minutes. In order to calculate the electricity spent during this time, you need to multiply the electric power by the time received:

If we take into account that the drum motor also works during heating (it scrolls from time to time), then the resulting figure can be rounded up to 1 kWh.

Pros and cons of filling the washing machine with hot water

  • energy savings - water is no longer necessary to heat;
  • reduction of washing time - it starts immediately after switching on;
  • saving the resource of all units and, first of all, heating elements;
  • saving the family budget is as a consequence;

True, I must admit there is one minus. The consumption of hot water is increasing. But if you do not have water meters installed at your home, then this can be neglected. To check the economic effect of using this trick, due to my meticulous nature, I nevertheless decided to make small economic calculations and find out how profitable it is and whether the power consumption will be much reduced.

S.S.V.:

I have hot water connected from the day I bought the car. cars (my idea) for about seven years, probably, and everything is OK.

will overheat and the machine will fail. it initially has a spiral for heating water. and water flows from a faucet at a certain temperature. and in the machine you can adjust the degrees as you wish

Darya:

No. No.

some kind of genius, someone would be glad to send you to the manufacturers, they gave a premium, and those who supply water heaters for cars open a hunt for you

Lelya:

Not all clothes can be washed at 70 degrees. , -can shed or run away

Vladislav Melnikov:

No, you can break the washer, because the electronics in it are made in such a way that it would determine by itself how much to heat the water. And if water of 60 degrees instead of 30 goes into it, I think nothing good will come of it

Avlaak'h Mage:

I don’t think this is a good idea because there is soaking before washing, and if you soak in hot water, the dirt is brewed into the fabric and then washed off worse, and the inlet valve is not designed to supply hot water

Svetlana Mayorova:

No. And how will it cool to 30 degrees?

Rostov:

The machine rinses with COLD water. On and not all things can be washed in hot water. You'll just ruin things. And the machine won't last that long. You already answered this question yesterday...

Marina Molchanova:

how will you wash when the hot water is turned off

Natasha:

There are some models of washing machines, mainly designed for small businesses, they are connected with two hoses, both hot and cold water. But at the same time, the prices are appropriate. As for rinsing things in hot water, the service life of things decreases at the same time.

Grandfather Au:

water control equipment will be covered

mariman:

Yes, this is a good idea and by the way it has been used for a long time. I put the usual built-in mixer and connect the washing machine. Hot water is used only during the first set of water, then it switches to cold, (in winter to cool - by adjusting the mixer) centralized hot water is often a little lower (or you adjust the mixer so that it is a little lower than you need), the heat is only slightly adjusted to the desired temperature. But rinsing should take place in cold water, it's just that all the dirt precipitates during cold rinsing, and it is also fixed, the paint of your fabric is not rinsed, good luck)))

Alexey Malinov:

Our hot water is often cut off. And then how do you wash it?

rinse stage. what to consider and how to improve

If you use fabric softener, then pour it into the special compartment of the tray only after you “refill” the washing machine with water, otherwise you may inadvertently simply wash it off. Of course, the consumption of electricity at home will not increase from this, but the money for the air conditioner will be wasted.

Yes, I missed one point. It doesn’t matter which program to set, that is, the washing temperature, as long as it is not higher than the temperature of the water that you filled in before, otherwise the “smart” machine will start heating it to the set one, and therefore will consume additional electricity. I think it is easy to determine the organoleptic method, that is, by touch.

Let's talk about rinsing.Modern washing machines are set up so that not only washing, but also rinsing takes place, almost in a mug of water. For those who are not satisfied with this state of affairs, I propose the following method. But I immediately warn you that he assumes that at the time of washing you will have to be at home. That is, by and large, the function of automatism of the rinsing process is lost.

So, we put the machine for washing, we catch the moment when the rinsing process begins, then through the same tray we add cold water at least a full tank and we can “sleep peacefully”. Unless, of course, you are not too lazy and not a burden to do this and time allows. But, in my opinion, many pensioners have enough free time, especially when it comes to saving "for the home, for the family" and the quality of the work performed.

Good luck to you! See you soon on the pages of the Penserman blog.

Vyatka automatic machine and modern washing machines

Why did I remember her? And besides, it was designed according to Soviet household standards. Or rather, taking into account the fact that we use centralized hot water supply almost everywhere, unlike Western countries.And therefore, it was supplied not only cold, but also hot water. Naturally, the heating element was used there on a case-by-case basis. So washing did not have much effect on the overall electricity consumption of the house and its savings were on the face.

When an imported machine appeared at our house - an automatic machine, I lamented for a long time that it was impossible to pour hot water from the water supply there. The trays (where the powder is poured) of the Soviet, unlike imported ones, did not allow this to be done - water poured onto the floor. But then it was not so much the saving of electricity at home that bothered me, but rather the weak electrical wiring. Now this problem has disappeared since I replaced it.

So, once a drain pump jammed on it (though, unlike the previous one, already in the fifth year). The master, whom I called to the house to replace it, during the conversation advised me to fill in hot water for washing, they say he uses this method at home and the energy savings are very decent. He even told how he brought hot water to the fitting of the machine through a tee. And frankly, I convinced him.

Final economic calculation and conclusion

So, with one wash using hot water for this purpose, that is, without heating it, we have:

  • Energy saving: 1 kWh;
  • Saving cold water: 0.015 cubic meters;
  • Hot water overrun: 0.015 cubic meters;

Today, in our city,

Electricity tariff - 2.02 rubles per 1 kWh;

hence:

  • Savings per wash without water consumption: 1 * 2.02 = 2.02 rubles. (if water meters are not installed at home);
  • Savings per wash, taking into account water consumption: 2.02 - 0.87 - 0.12 \u003d 1.03 rubles. (if water meters are installed);

As you can see, the savings are not that big. Of course, if you do not consider that the resource of the heating element will increase. Its replacement, along with work, in our city, while it costs within 1800 rubles. So decide for yourself whether you should use this method of saving electricity at home. But, if you still decide, consider some of the nuances.
