Well, I just have a washing machine and a vacuum cleaner. I will defend myself till the end, they are second to none. Really. The washing machine is already 9 years old, it goes almost every day ... perfection in every detail, but it was brought up the winding stairs by a 4 boy, 98 kg is doing its job

They advised me not to - and I am grateful for the substantive arguments - and not only in this thread: https://www.elektroda.pl/rtvforum/topic3629334-30.html#18291556

Hmmm, I don't think you can. Isn't it about the fact that in the dryer with a heat pump there is a refrigerant-like factor and it brings a certain part in the exchanger to a very low temperature, probably even below 10 degrees. And when warm, humid air flows into it, the water condenses and dry air is flowing back into the drum. In an ordinary dryer, of course, there is also an exchanger, but it is not cooled, it has room temperature and therefore the air must be much hotter for water to condense in it. If only in the dryer, I would just lower the temo. Probably such drying would have to take 5 hours. I do not say that it is exactly as I wrote, but I guess that's the point ...

If it were as you say, drying would not take longer than in a dryer without a heat pump, but shorter.

It takes really slightly longer http://dagd.pl/index.php/2018/04/16/jak-wyroz...uszarek-i-na-jakiej-zasadzie-one-funkcjonuja/

Dorill, you forgot about one more fact, the warmer the air blows, the faster the water evaporates from your clothes
There was no topic because I wrote a post when you provided the link

Old saying: the wind dries and if it is to blow warm air well, there must be power to heat this air.

Well, the rule is more or less that the pump is the cold place where it condenses. For sure, I noticed that in the dryer with a pump the wind is greater, you can hear it after the operation of the device. It is definitely louder than a regular dryer

In the one with the heat pump, which I measured, you could hear the "hum" of the compressor and the noise of the rotating drum. With this volume, I would call it louder, but reasonably. And it is differently louder, less noisy and more hum.

Again, but this is the last one, because I have other classes, and I have no interest in writing here, because I don't trade hair dryers or household appliances. Moreover, it is clearly stated in the testament of Jesus Christ that: "For the time will come when they will not endure healthy teaching, but according to their liking they will gather for themselves teachers, eager for those who tickle the ear," - so my efforts
1) There is no technical problem that the dryer achieves a low drying temperature without a heat pump. NOTHING. A slightly shorter heating spiral and lower the temperature from 60 to 50 to 50. If it were to protect clothes, such dryers without a pump would be sold long ago, and sellers would praise and squeeze them. The rest here: https://www.elektroda.pl/rtvforum/topic2918741-660.html#18345344
2) Then: supplying the heat pump dryer with the hot medium. Just undress and measure. The power supply will exceed one hundred degrees Celsius. But this is just a curiosity The design and power show that the efficiency is low in such conditions, the power compared to classic heating methods is also low, and therefore the temperature. However, it is enough to stuff things into the dryer drum to reduce the air flow (practically clog it) and the temperature of the dried clothes increases (the efficiency of the heat pump decreases). This is a secret why some people complain about dryers (of all kinds), but shhh, it's a secret
3) If it were important for the dew point, drying in a heat pump dryer would be faster, not slower. Therefore, this fact (colder condenser) has no practical significance, although it is better to condense on a colder element. Only practice shows that the heating power, airflow or air temperature are of greater importance - I have no basis to define what is the most important. For us (me and my wife) it is important that washing, drying and washing in the dishwasher is short.

Ehhh and I run the dishwasher for 3.15 h?

But why buy with a heat pump if it is more expensive by about 5 cents.

EU ecology pane. a little more and they will only be with the heat pump. I bought it without and I have been waiting 19 days for delivery

What kind of money did you buy?

They describe it oh and ah, but it turns out in use. as I wrote earlier, I will check the drum temperature on various programs.
if it will be the same, the whistle comes back to the store

A great idea with this temperature measurement, I also want to measure my own, but I do not have professional equipment. Do you think that when you break the drying process and put in such an ordinary home thermometer, the result will be reliable?

Once on YouTube I saw a guy measuring with special equipment, it was a whirlpool dryer. The temperature was around 47 degrees, I think

Added after 14 [minutes]:

I found the dryer reached 44 degrees, but I will see mine give

buy something like that

I'll buy it and I'll do some tests. I use 3 programs usually and on each measurement with it.

But I would like to do it with the washing and I wonder if it will break? Because empty may not be adequate. What do you think?

I am after a service technician visit, and I also have an e-mail response from Bosch regarding the previous controversial issue of shrinking clothes.

First, an email reply from Bosch:

"Good morning sir,

Thank you for sending your inquiry

First, check whether the T-shirt can be dried mechanically - the marking on the label.
Another issue is the quality of the material from which the T-shirts were made and the comparison with the description of the program intended for drying
The heat pump dryer certainly does not dry at too high a temperature, but if you have such a reservation, the service can check the temperature of the process heat. "


The service technician was today. The dryer is, of course, the most efficient and there are no problems with it. Temperatures checked, the highest temperature is 56 degrees. Moreover, in this type of dryer it is almost physically impossible to achieve a higher temperature and thus overheating. The amount of gas in the system does not allow it.
The service technician also confirmed what they wrote by e-mail. Some fabrics even shrink in a heat pump dryer and THIS IS NO ADVANTAGE. You have to follow the tags when you have doubts about some clothes.
I also refute the MYTH that the heat pump dryer does not shrink any clothes, because it is not true. Yes, some do shrink.
In addition, the service technician confirmed that you have to be even more careful with a classic dryer without a heat pump - he has one himself.

Below, I enclose a confirmation of the service technician's visit.

Well, I am all the more glad that I do not have such problems with mine and that I can dry everything. It seems to me that mine has a lower drying temperature because I have opened it many times during work and the laundry is only lukewarm. I even wrote yesterday that the guy measured the temp on YouTube and it was 47 degrees and at such a temperature it's hard to shrink anything

Hello . I have read the entire thread. Due to the small bathroom in the block, a pump dryer is available. And here the stairs begin. I was thinking about Bosch, but I am discouraged by this one-way turn. Husband had a drink on LG with a closed circuit, self-cleaning LG RC90U2AV4Q - cost 3300

But somehow I'm not convinced of it. No access, nothing to clean?
The second option is to choose the cheapest one with a pump and with an extended warranty. I would be grateful for any opinion. Thank you

For my part, I can honestly recommend electrolux perfect care 800. One of the main models, I almost paid 2400 two years ago, now you can get it for 2100-2200. 4 of the same models work for other people in my family, all equally delighted

But what do you mean, a dryer without a heat pump has the same dimensions as with a pump, it takes 1.5 kWh per wash, 2.5 kWh 2 washes.
Why complicate your life.

I did just that (because I got stupid after reading the whole thread), I bought one of the cheapest with a heat pump for PLN 1799, Bosh series 4 because it was on sale. It turns to one side, but does not twist the clothes - I didn't notice anything like that, even when I was washing my linen and luggage. Drying on the mix program is approx. 2 hours, the time is shown at the beginning of 2 hours and 2 minutes, but it usually ends after 1 hour and 45 minutes, unless I had a bad wash during the spin process and did not spin properly. The washing machine has a default setting of 1,200 revolutions. I wash my laundry only in capsules without any fabric softener, after drying it smells more intensely with detergent than before drying and everyone is just asking what rinse aid I use I do not have a comparison of electricity consumption yet, because I will get the first bill after the New Year, but it will also be distorted, because I bake more before Christmas, so the oven will add its own ...
By the way, I cordially greet you, because here on the topic of drying (and I can probably add about washing, because one is related to the other), however, almost only men are involved ...

Do you have a problem with shrinking clothes?

Gentlemen, of course, also greet, just envy the wives of such interest ...

I think not. I haven't cramped any cotton things like T-shirts or pajamas. Someone wrote that if cotton were to shrink after drying at such temperatures, then it would be fearful to iron it. I don't dry viscose stuff too often though. They get a little shrunken and after spinning at high speed, so I don't blow them with the dryer very often. So in general, I don't complain about shrinkage either.

What do you think about this one? My husband probably insisted that class A +++ BEKO DH8634GX dryer. I am tempted again by Bosch or Elektrolux.

Today I brought home an electrolux without a pump. The first thing that attacked me in the store was the seller, why I take the heater and convinced me that after a year the bills will be 1000 PLN higher than with the pump and he started some calculations to prove it. I didn't have much time, so I ironically told him that electricity was cheaper since the new year. Regarding drying, I have a scratch 1 and a slightly damp wash, because a moment had to hang before I started the equipment. Generally, after less than an hour, I took out the dry ones and threw everything as it flew, but only delicate options. The only thing I noticed was that there was a glass of water in the container, but when I took out the condenser, some water spilled out of it. Maybe there was not enough water in the clothes to make more dripping

After drying for the first time, I had almost no water and searched around the dryer. After further drying, the amount of water is normal, around 2-3 liters.

Yes exactly. From the second drying time I pour at least 1l of water. So far I am happy with the drying and another plus is the additional heating of the bathroom during drying. Earlier, when dripping children, we heated the "farelka" for about half an hour and now it is enough to plan drying in the evening and additional savings.

I would not breathe this muck from drying, only chemicals, while drying I open the window.

I recently did this experiment with temperature, although I did not buy professional equipment, I measured it with an ordinary thermometer. I put it between the washing after 50 minutes of work and after 80. In both cases it showed me 27 degrees (!) For sure the airflow itself is a few degrees more but the laundry itself does not heat up above 30 degrees. I do not know if each one heats so little, or only electrolux from the perfect care series. It is true that in the advertisement they even said that you can dry things that are not adapted to the dryer, but I think so and so that each dryer with a pump heats up similarly. And as it is commonly written that the temperature is 55 degrees, I say that it is much less in mine. Happy holidays to all forum members! :)
