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

UUUUU Dorilll, is your dryer going to end? 27 degrees is a little haggard.

From the very beginning, the laundry was slightly warm, even summer. The cycle lasted 1.50h, I dried 2 thick hooded sweatshirts, a towel, a large tread from the table and other small items, of course everything was dry. It was spun at 1,200 revolutions. I don't know what would end there. I think that the air supply temperature itself is higher, but the laundry itself will not heat up to the same temperature as the air.

When we are outside, we have 30 degrees Celsius and the wind makes our laundry dry in the blink of an eye. So why wouldn't it work in a dryer?

Gas loss in the heat pump or your measurements are inaccurate.
On 27.12, which is almost a month from the purchase of the dryer, they have to deliver it to me (condenser dryer without a heat pump), then I will make reliable measurements of the temperature of the dried laundry on various programs, electricity consumption, time and whether the clothes have shrunk. on New Year's Eve I go to a friend who has a dryer with a pump. I will try to take temperature measurements. If they are within 30 degrees, I will return my honor

Well, mine are definitely not authoritative, it was an ordinary term. There is a video on YouTube with a probe in the drum and the dryer heated up to 44 degrees there. I think that's how it is for me. If the gas ran out, the drying effects would certainly be bad and something would pop out or the cycle would be extended. I will only add that the dry is mixed and there is a lower temperature for cotton.

And by the way, what is it that you've been waiting so long for your dryer? Some circus, I know that you bought without a pump, but at least in rtveuro household appliances are bosche and electroluxes without a pump available almost immediately

I live in Belgium and there is a lot of emphasis on pseudo-ecology, so in the store you can buy a pump dryer right away, without a pump, you have 2 crap models per piece, you wait 2 to 4 weeks for the rest. As for Bosch equipment, I do not want to comment on the forum. Anyway, a colleague of a few pages earlier described the operation of his new Bosch dryer.

I understand, then until later!

Phew, I got through the whole thread ....
The first question, Perhaps I missed it, Doril, who specifically has the perfect care 800 model, there are several of them.
Second question, are you using these extra balls for drying?
And the third technical question, someone tried to put an ordinary filter, for example G3 or G4 class, in front of the heat exchanger, the one that is so messy after time?
The cost of the filter at the manufacturer of recuperators is a dozen or so zlotys for 2 pcs. Looking at the size, the dryer will have 4 to 6 replacements.
I have a small room, unfortunately it will be with a pump.

My model is EW8H458BP. I don't use crutches either, only tennis balls when I dry something with fluff. I used to think about this filter, but that was it. However, after almost 2 years of use, the condenser is practically clean, so the double one under the door does the trick. I think that the pump or the programmer will fail sooner than it clogs, but we'll see ...

I wouldn't be up to anything here. Such a filter is additional resistance (mainly for moisture), as if you were drying on a clogged factory filter. It can distort the dryer "thinking", increase power consumption, airflow and drying efficiency, and even damage the deck.
Proper handling of the dryer will ensure a clean exchanger for many years.

And the dryer arrived after a month
It looks better than the pictures. The buttons are slightly raised, but here it is a tactile surprise the first quick test was carried out on 4 damp T-shirts. course mix program with 15 minutes for measurements only
and kicked the video, I forgot to hold the phone horizontally
https://drive.google.com/file/d/10oI7OVJJBMVKhFBGMa77HJ-a8dM7uRlH/view?usp=sharing
the washing temperature reached 55 degrees

the first real cotton test for sure with 8 kilos. Almost the entire 10kg washing machine after spinning


we take off

so far the heater consumed less than 2KW
from 19:55 she jumped to 2.35KW and kept the temp 56 degrees



20.17 went to 65 degrees


tutal you can see how it cuts off the heaters above 65 degrees


and from 20:50 it starts to raise to 70 degrees and then cools down quickly and so on several times



21:04 end and cooling down the laundry
185 W was already downloading to the very end



the end





laundry smelling well dried and the wife smiling

Well, it's not bad, almost 80 degrees. Try on delicate programs or the temperature is much lower.

What was the total electricity consumption for the drying cycle, because it does not show on my phone? ??

According to the photos you have loaded it "healthy" We put less in so that there is more free space in the drum.

total 2.7KW and it was the most hot and energy-consuming program (bed linen and cotton) with an overloaded dryer, Tracksuits, warm fleece pants, sweatshirts 2 towels large 2 T-shirts over 10 table runners, etc. this amount of laundry would certainly not fit on a traditional dryer (remade more than once). The dryer can be seen that it controls the temperature. it rises by 10 degrees every now and then and then dries at 65 degrees, so for me it's mega because it's practically the same temperature as washing. as for the end of drying, she went a little crazy with the drum and the temperature jumps to almost 80 degrees and quick cooling (I think they know what they are doing). The laundry does not prick and smells really good. From Monday I will start testing on other more delicate programs.

A decent entry must be admitted :-)

How hard did you spin the laundry? Because the wear would match mine. As I checked in the past, it came out within 2.2-2.3kWh for ~ 6.5-7kg of laundry spun in 1600 revolutions.

I think it was 1600 revolutions but I'm not 100% sure

So it came out 2.7 and according to the product card there are 4.7 only they probably count at 1000 revolutions when centrifuging. A request for the same test at 1000 rpm and we will see what the difference will be to the theory

I now have a 1000 rpm spin washer and the previous one was 1200 rpm. We did not notice a difference in the drying time, so I did not make measurements with the instruments.
I once found information that the drying time will increase by 30% when changing the spin speed from 800 rpm to 1600 rpm. So a very significant increase in the spin speed (100%) only slightly (30%) changed the drying time.

These measurements are consistent with mine: https://jackiewiczowie.blogspot.com/2015/01/zuzycie-pradu-przez-suszarke-do-ubran-i.html

We will start testing on Monday.

And I have a question, do you use water after drying for irons / steamers? According to the instructions, it is written that the water after susseniu is distilled and after filtering you can lac to irons. And the second question is when does it soften? Because my network is quite hard.

No, though you can. We use osmotic filtered water for the iron.

I can see that this topic is immortal.
Do your pets also jump into the drum as soon as you get the dried stuff out of it?

Best for the New Year ...

Not yet But my dog sensed that when I pulled out dry laundry, there were such nice balls inside and he would like to play with them, whenever he has the opportunity, he stands in front of the dryer, wagging his tail and looking expectantly whether he can take one or not. as always, no ...
All the best for the New Year

I also grew up to buy a dryer. I did some reading and found it would be a condenser without a heat pump. I was wondering whether a new one for PLN 1600 for two years of warranty or a used one. I have had such a problem with choosing a washing machine before: https://www.elektroda.pl/rtvforum/topic3382484.html
After this positive experience with the washing machine, I went yesterday for the Miele Novotronic 4960 C dryer for an astonishing price of PLN 300 (prices on the market oscillate around PLN 500 - PLN 700). On site, the seller connected and showed for a moment that it works and heats up, but it is known that everything will not work. At home, I took everything out for cleaning before using it for the first time. It turned out that the exchanger was so dead that the dryer was not allowed to function properly. Attempting to clean the exchanger with a strong stream of mains water did not help. I flooded the exchanger with domestos and poured it with boiling water, but through the gaps it is still dark. Already a bit concerned, I figured out that I needed a very high water pressure that I would find at the car wash (no carcher at hand). A trip to the car wash, 2 zlotys and a rinsing program. Bingo!
If someone has such a problem with the exchanger, I recommend this method
The dryer dries nice, you can still smell the rinse aid
Finally, the end of a room-use dryer and the problem of several washes in a row for the amount of PLN 300 plus PLN 50 for fuel. Of course, electricity costs, but this additionally warms my apartment.
I recommend it to anyone who is still hesitating.

ZAB how are the tests? I have been measuring each drying on January 1st. I wait until the last one to have a whole month and post my results.

I am also curious, but it is most like the temperature on individual programs

My electricity consumption during washing and drying:
Samsung A + washing machine, condenser dryer without B pump
20 washes and dried
Total consumption of washing machine 13.1Kwh, average 0.65
Total consumption of the dryer 36.5Kwh, average 1.82
As for the electricity consumption of the dryer, the manual provides the value according to the standards for the eco program and full load with spinning for 1000 consumption, 4.27kwh. My biggest consumption was 4.1 when drying from 2 washing machines, also the dryer was overloaded, spinning at 800 and setting extra dry. After drying, the tanks were full of water, i.e. about 5L. So even here it was not possible to get 4.27. With normal drying, i.e. transferring the entire laundry, the consumption was between 0.7-2.6 Kwh. As for the temp, I will not say because I did not measure it, but when I opened it during drying, the drum was scalded. I will add that I throw everything as it goes and so far no losses. The only thing that in the case of clothes adds delicate options (the power then drops to 1600W), while towels and bedding without this option and the power is then 2300W.

@ krzysztofm1989 And now by comparing your data (analogous to mine) with the following quote:

However, 3 kwh chicken is quite a lot. Today I put in 4 washes and 4 dryers and with this consumption of more than 10 kWh, it would be just drying

And when comparing the prices of dryers, their degree of complication and hence failure rate, I will still insist on a dryer without a heat pump.

Well, I had 2 types of dryers, previously Bosch without a heat pump, and now electrolux with a pump. Never in my life would I go back to that dryer, it was just plain to see that things were exhausted. As for the failure rate, I can't really say anything, because I have it for less than 2 years, but it works almost every day. So far without any problems ;)

I would like to add that it is so delicate that I have recently dried a cashmere sweater in it, it looks like new
