Bosch Condenser Tumble Dryer: Comparing WTW85460PL Heat Pump Model and Conventional Options

Can someone do such a measurement on a dryer with a pump? Only for a month so that you can compare. I wonder if the consumption will also be much lower than that stated by the manufacturer.

I would love to do it, but I have neither a measuring device nor a possibility because I have the socket behind the dryer. But on average, I have 20-25 dryings a month and I haven't noticed an increase in my electricity bill, that's all I can say.

Added after 1 [minutes]:

Or even 25-30 because it happens that it is washed and dried in the morning until the evening

I can only say this ... who hasn't, doesn't know.
I guess even in this thread (only much earlier) I questioned the sense of buying a pump dryer until I found out for myself about its advantages.
Of course, you can buy a car with an engine powered by a carburetor ... because it is simpler, at least the on-board computer will not immobilize the car.
However, it is better to get out of the forest, because complex hybrid vehicles perform better.
Simply now, simple mechanisms that did not break down too often break down too often and cardinal design errors are made. Probably because the hardware is no longer designed by people, but by computer applications. People only make sure that the production costs are as low as possible.

I do not know how much you pay bills, that you have not noticed their increase, but the dryer is not a perpetual motion machine and these 25 cycles must increase the bill by several dozen zlotys.

Which does not mean that I have not used it for months. People now travel, and they can live comfortably ... :-D

Exactly. I see advantages for producers and sellers. Only disadvantages for the user.
Which does not change the fact that people are taught that new = better. Yes automatically. They will always buy new ones, otherwise they will think that they have bought worse, because it is new, it has to be better. So now people are being taught and that will not change. I am realist , I know that my entries will reach a very small group of people. You won't win (usually) with a powerful advertising machine. Anyway, when people buy expensive, they feel better. Expensive has to be better. Therefore, it remains only to read the threads afterwards: oh dear, you broke down what that could be.
Now I am waiting for dryers with Internet connection and telephone, or maybe they already are ...?

Well, but my friend did the same .He had a string to hang up, but he bought a newer one, a mechanical dryer ... Much more emergency than a string. And what would a colleague do if there were no traditional dryers, but only with a heat pump?
Also, rather a lack of consistency in the arguments.

Maybe instead of talking about what is better, let someone who has the pump measure the consumption and we will have some reference. Unless someone has measured it and it is like without a pump and I do not want to admit it. And yet another point. Measured with the pump after several years of use. I wonder what the consumption is there if you can't clean the condenser.

Borutka has exhausted the topic, everything is perfectly written. I had both and although I would have to change the dryer with the pump every 3 years, I will not return to the usual dryer, even if I had it, I did not recommend other dryers. Since I have a pump, I have already persuaded 5 people. As for electricity, I did not notice because I never had the perfect, always the same electricity bill. There was always a little less or a little more. And if I collected electricity bills now, I would not be able to say that you have a higher bill since September because there is a dryer. On you tube, such a golden man wrote that his monthly bills increased by PLN 10-15, and he dries even 2-3 times a day, so definitely more than me, so I am not able to notice this nozzle, for example

Added after 5 [minutes]:

In an old dryer, I would sometimes take something out during the cycle because I did not want to murder it to the end. Before I threw all these things in this drum, my hands were almost burned and the steam was blowing like a dishwasher on some program of pots. So why work things at 30 degrees, for example, Black have a ride in the dryer anyway. In the new equipment, the laundry is only lukewarm, and I don't know what will not convince me of the superiority of dryers without a pump.

Buddy ... I think you want to break down an open door. After all, the manufacturer has already pre-determined the energy class of the device. In practice, this difference will be rather insignificant, not worth writing a doctorate on the subject.

So how do you relate to the data obtained by me and frebsd? I don't think I sensed them. I am curious because maybe in the dryer with the pump the manufacturer also overstates the consumption and it turns out that instead of 1.5-2 Kwh he takes 0.5. I do not mean praising these or other dryers because I see that this topic is escaping this way. Everyone has what he has and it is natural that he will protect it.

Simple calculation.
A traditional dryer takes about 2kW and a standard load is dried 50-60 minutes.
A similar load with a pump dryer (in the mix program) dries 100-120 minutes, while mine uses 600W. Even if the pump or the heater works continuously, the power consumption would be 2kW and 1.2kW, respectively.
In practice, it depends on the room temperature, the type of fabrics and the spin speed, etc.

It is a bit like burning in a car. One measures 4/100 km and the other, in the same car, has 6 liters. And the manufacturer says 5 liters.
I do not defend anything, I only judge subjectively, or rather objectively.
Once my dishwasher dried the dishes in half an hour. The new one didn't do it in an hour and I had to turn on the turbo drying. Now the new one dries like the old one, but it also uses electricity like the old one, because it doesn't want to dry it for free. But it has to be dried and that's it.
Also, I think it's a waste of life for such calculations.
There is also the question of the accuracy of the measurement. You may be using some aliexpress toys and the accuracy may vary greatly depending on the type of load

Ehhh, if you know better, what measure and how much it is ok. You will soon write that I have falsified the data. Best regards to everyone and have a nice weekend

I believe that these data are not overstated, but as it is written, it refers to, for example, 8 kg cotton spun at 1000 revolutions. I think that none of us load a washing machine for these 8 kg because it is a lot, the laundry would have to be crammed, and sometimes we have not only cotton but some other, artificial material that takes up as much space as cotton and a lot of vase. less. So the dryer has less to dry and it is much shorter. For me, this reference program is calculated that it takes 150 minutes for the cotton program, i.e. with a higher temperature. I dry with the mixed program, the temperature is lower there and the dryer usually runs 100-110 minutes. In addition, I always have a lot of slack in the washing machine, because I have a feather for some quick mixes, so I think mine uses 1kwh with a small hook, hence I do not feel an increase in electricity bills

Added after 4 [minutes]:

The power is 900 watts, the compressor runs continuously for 40 minutes, then it turns on periodically every now and then, and the last 20 minutes is cooling, airing with cold air, so the power will definitely drop. Even the cable does not heat up when the dryer is working, and this happens even when the washing machine heats the water. So it can be said that the pump takes little electricity. As for the clogging of the flapper, I clean it every 2 weeks, I consider its condition to be very good and drying does not take more than a minute. And drying has a lot behind it

Added after 2 [minutes]:

I will add that the laundry is not perfectly spun because I have 1200 l revolutions, but the feathers for some mixes, dunks, and there is spinning for a minute, sometimes on cotton, this spinning lasts for 5 minutes and it seems to me that drying takes these 10-15 minutes shorter. But I believe that it is not worth it because of these 10 or 15 minutes to force washing machines and things

When I read this thread, I have the impression that the heat pump is "evil". Everyone has a refrigerator - there is a heat pump there too. Whether the pump will run for a long time or not depends on the performance. The technology itself enables many years of operation. After all, air conditioners work for hours and years and do not break down too much. However, I would like to draw attention to the technical aspect of the operation. Without a heat pump, the condenser must be cooled with outside air. It has 20 or more degrees. If we do it in a small room, it heats up, the temperature rises, and the condensation efficiency decreases. Dryers without a heat pump operate at a higher temperature than dryers with a pump. A heat pump dryer is an ideal technology and it is not only about economy. Thanks to the pump, we have a "cold" and "hot" episode. The cold one is for condensation, the hot one is for reheating. The whole can operate at a much lower absolute temperature, and the heat pump ensures the required temperature difference anyway.

Can you answer a few questions for me to clarify your point of view?
1) Uptime depends on the execution, and does the technology itself ensure trouble-free operation comparable to classic dryers? (see point 2)
2) What about cleaning the heat exchangers? Have you ever disassembled a dryer (any)?
3) Economics. Why should I overpay for a heat pump when the simpler and cheaper technology works flawlessly?
4) Ecology. Why should I produce a complicated machine containing greenhouse gases, various metals, lubricants when I can make the machine simple? Why complicate?
5) Ecology cdn. - i.e. about servicing - an ordinary dryer is trivial to repair. A dryer with a heat pump, if it is already repaired, it is probably not stationary, only in the service (you know, renewable fuels used for its transport). Unless it turns out that it is cheaper to buy a new one. Plus, let's hope these greenhouse gases don't escape into the atmosphere.
6) Do you want to say that the heat pump dryers produced nowadays work as flawlessly as classic dryers? And they are just as easy to repair, but are heat pump dryers replaced with new ones - which means that new garbage is constantly generated?
7) What are the advantages of a heat pump dryer to pay more for it? The above writes about the mythical "murder of fabrics" by a dryer without a heat pump, only evidence for this was lacking. Is there anything else besides that? What are the advantages of a heat pump dryer - also a question.

For me, the solution is very simple. Environmentalists are trumpeting that "greenhouse gases are bad", the climate is bad, etc. So the heat pump dryer is also not good, right? If someone is an ecologist and supports them, and does not lie, then he should not use devices with greenhouse gases? In addition, a dryer without a heat pump is cheaper, less emergency, and if it breaks, it is trivial and cheap to repair.

PS .: I keep my fingers crossed for your heat pump dryer to work flawlessly. What model do you have? Can you upload a picture? Can you perform the measurements of energy consumption, which we write about above?

Come on, river. The main advantage of the pump dryer is that it dries the air at a temperature almost the same as in the yard in summer. I noticed that the pump dryers criticize only those who have the usual and no one had to deal with the pump. There is a HUGE difference in dry washing, just touch. Nobody will tell me that some galoty, or a sweater dried 20 times at 80 degrees will look the same, or a dress or a t-shirt with a print. Well, there is no such option. As for the price, you say they are so expensive. I look at the prices, the Bosch or electrolux model costs about PLN 1600 and the cheapest model beko with a 1800 pump (my friends have this for 2 years and praise them, the equipment flies as it should). And as for the failure rate. Your own will never break? If someone does not have a knack to repair and lives, for example, in the Tri-City, even repairing an ordinary dryer will be expensive. In fact, it is better then to dry it on a line because it will never break down. The author of this thread wrote after almost 5 years that his dryer with a pump works and is very happy, he washes 5 times a week. So if someone has a standard 2-washes a week, such a dryer would already work for 7-8 years. A little? If someone washes every day, nowadays there is no chance for any equipment to be used for longer than 5 years.

Added after 3 [minutes]:

How can you keep your fingers crossed for the dryer to work flawlessly? It simply cannot be done, because it is hardware and it breaks down. This is normal and natural. On YouTube, the guy assessed the elecrrokux dryer, he is over 2 years old and he dries on average 2 times a day. Already slightly a thousand dryings are behind them. And what? The dryer works the same as on the day of purchase. So let me tell you that every dryer with a pump is doomed to clog after 2 years, after 2 years I am almost perfectly clean. Mostly the programmer or the pump before it clogs. And if it happens with such frequent use only after 5 years, I will still recommend the heat pump

Added after 36 [minutes]:

I would like to add that if it were not for the difference in the washing, he never changed the dryer to a heat pump, continued to use the old Bosch and if it broke, I would buy a dryer without a pump again.

I bought the current dryer without a heat pump in early 2014. And it was my choice to buy a classic model. Those with a heat pump were only about PLN 1,000 more expensive (then). I used heat pump dryers in premises that were rented to me by the company. I know how they work, but I only lived there for weeks. I've seen (and used) classic dryers from the 1980s too.
I am constantly under the illusion that someone has a good reason why heat pump dryers are better for such an ordinary home user. Especially since so many people are talking about ecology now, and here's another topic to discuss: greenhouse gases.

Again, based on Bosch hardware, you rate other dryers. PS .: Have you ever wondered where these lint on the filter in your dryer come from?

@krzbor If you have time, please, refer to my questions.

@freebsd
ad.1 The technology itself ensures the necessary failure-free operation. Just look at refrigerators that last 20 years or more - it's the same technology. Air conditioners also work for 10 years or more and work in the summer for more than 10 hours non-stop.
ad.2 The heat exchanger must be cleaned because its efficiency drops drastically. I bought a Bosch model with a self-cleaning exchanger (condensed water is used for this).
ad.3 If in an ordinary dryer we need, say, 40 ° C lowering to condense the water, we have to heat everything to 75 ° C to get 35 ° C in the condenser, which is not easy with 23 ° C outside - and such air is at the inlet as cold. With the heat pump, to get these 40 degrees C difference, it is enough to have 5 degrees C in the condenser and 45 degrees C on the outlet. I do not know these temperatures, I gave it as an example, but in general it is about it.
ad.4 As far as I know, greenhouse gases are not currently used. The heat pump is more complicated, but I explained the meaning in point 3. Currently, ecology is primarily about reducing electricity consumption. Apart from the topic, for everyone to be satisfied (producers, distributors, customers and finally the environment), recycling is the best. I bought my dryer OleOle, where old equipment is free of charge.
ad.5 As I wrote, greenhouse gases are no longer used. As for the complexity - well my father fixed the toddler himself, in which even the engine could be pulled out by yourself without too much trouble. But I don't want to drive a toddler anymore, and my engine is a whole lot of electronics with even more sensors. When I asked when I was to come for the inspection, I was told that the computer would inform me about it, but the first time after 30,000. or 2 years - you don't even have to change the oil before!
ad.6 I am the new owner of the dryer. Certainly, the technology itself does not mean failure. Failure rate is the result of the manufacturers' lack of effort (or perhaps trying to break down after the warranty . The repair is definitely more complex
ad.7 Apart from the ecology (lower energy costs), the lack of room heating (especially troublesome in summer), for me, the technology described in point 3 is important, as it results in a much lower drying temperature. I will not hide that as an engineer I like the heat pump technology, which perfectly fits the needs of the dryer. We have two closed cycles - cooling and heating heat pumps and a laundry drying cycle with condensation. Many people think of a heat pump as an economical heater. But that is not the point! The "cold end" of the heat pump is also used here, as described in item 3.

Ehh, this discussion is getting useless. I do not judge the old dryer, because it was functional, the proof of this is the last preface, where he measured the temperature and reached 80 degrees. My wardrobe could not stand it. In Germany, I have a family, everyone believes that the dryers destroy things and dry them mainly bedding, towels and working things. Each of them has no pump. You mean cheaper and simpler is better. In terms of failure rate, it may be, but never functionality. Nobody will tell me that, for example, Zmywarlka for 1000 zlotys washes the same as this Bosch or Siemens for 2,000. Well, no, the difference is colossal. For example, I have Bosch for a second dishwasher for 4 years, I have not cleaned the fans once because they are all open. Friends have some cheap Amica and there is non-stop, fan clogged, filter or unwashed dishes, not to mention ergonomics. It is the same with dryers. I have dealt with all kinds and there is a gap between them.

Added after 14 [minutes]:

Another thing. Let's compare the cooktops. An ordinary ceramic, electric one can work for 10 or 15 years, it takes half an hour to boil a pot of water. A induction, a pot of water boiled in 5 minutes, you reduce the power, the soup stops boiling immediately. In electric, you have to wait for it to cool down. Overall the gap between the hardware, of course the induction will probably break much faster l. Here's a choice who cares about what. And that's it. I understand you are satisfied with your dryers and great. But don't be stupid saying that the heat pump in the dryer is a whim and an unnecessary expense. Oh no! As for the hairs, neither in the old dryer nor in the new one has any weight loss. So he denies these rumors that they are torn pieces of fabric, making things thinner. For example, I have a favorite sweater, an ordinary one from the net for half a year now. I think the prant was quiet 20 times, in no case it has clearances or other defects

Seriously? My penultimate refrigerator broke after warranty - that's how it was designed. China air-conditioning lasts 10 years? Are these 20 years old for heat pump dryers? Are you writing about the facts?

krzbor wrote:

Can you provide the model of your dryer and what gas is used in it? It should be in the instruction manual, on some card, or on the manufacturer's website. There should even be a warning / information sticker on the case.

krzbor wrote:

I won't ask how many percent of your old equipment was recycled. For example, Germany takes it to Poland. Just as much energy will be used for this recycling of equipment every few years. I will ask a question, but rhetorical: how much oil will be used to transport this new equipment, take the old one, and transport the parts needed in the factory to produce constantly new things.

No, I don't do for Bosch. He himself disqualifies their dryers for spinning in one direction and they have a self-cleaning capacitor that totally fails the exam. On the other hand, I believe that they make the best dishwashers, and their usability is even better than grinds. On the other hand, when it comes to washing machines, I think that Bosch is great, but the number one is Miele

But only dryers without a pump are drought at such a temperature, the gentle program slightly lowers the temperature

Well, no for such things, but I throw everything into the dryer, a lot of lace underwear, delicate black shirts with cuffs, and a lot of delicate things, and that's what I destroyed in the previous dryer. Even when I had some cotton blouses with long sleeves, it happened that the sleeve shortened. Underwear, such as boxer shorts or other items with elastic bands or cuffs, cracked after some time

freebsd wrote:

- from the manual: "The device contains R290 refrigerant, which is safe for the environment."

If this is the case, the pump beats the head and sews the dryer without a pump. Even if it breaks down, this value will pay off over the course of use. I am talking about a dryer for these 2,000, not 3

And thus it explains why I did not feel any increased electricity bills

krzbor wrote:

Thank you! And this is concrete - a factor that seems neutral for the environment. Although there were buoys on the electrode, whether the use of this type of agent in a car installation poses a fire hazard in the event of a breakdown / accident (and in the open space).

As for consumption, people have already reported the consumption of electricity here. Next data, a dryer with a huge load of 3 hours took 1.7 kWh. I think that I can safely write that my electrolux dryer for less than 2 hours on a gentle program consumes something around 1kwh, and that I often have less washing it and below
