I took 8 measurements with a pyrometer. At the end the temperature rose to 34 degrees Celsius.

I understand shooting at a locked door?

In my dryer without a heat pump, an average of 1.63 kW per drying time, which takes ~ an hour.
The difference is approximately 0.2 kW - this means a saving of PLN 1 for five dryings.

good result 4 hours of grinding and without a pump 1 hour is enough, you do not know it yet, but your dryer should also be discarded at the next collection of dimensions.

No exaggeration - I opened the door every time and measured inside. In addition, I checked with my hand, because people's bodies measured the temperature very well in this range - the laundry was "lukewarm".

Enter the drying temperature and kWh / kg of evaporated water. Comparing the consumption itself is pointless as it depends on the load.

Can you elaborate on the topic?

@krzbor Thanks for the measurements. I have collected data from a pump dryer for a while, but I have no time to visualize it.

He has a Pv brush and is dried with electricity from the sun, and he has 3 as long as he takes a washing machine and dryer. In the sun itself, it will wash it dry, as long as it shines.

Ps, the heat from the dryer does not heat the house because it stinks with detergents and softeners .......

When you have dryers in stock, always test them with two wet towels. Pumps usually take 2-3 hours to dry (wet, hand-wrung). The heater will do something like that in an hour or so, maybe a bit more to do it.

I have to refer to what you write, because it is a cosmos, and still someone less familiar will read it and will be suggested by these sometimes when making a choice. What percentage of the washes are hand-made to be tumble dried afterwards?
My contact with the dryers is small, I have had my first one for about 2 months, I must have read everything I can before and basically just got stupid. In the end, it was the pump, because a few times here I heard the opinion that the heater in small rooms is not a good choice (bathroom 4m2), in addition, both devices on one security. In some respects I was not convinced by Bosch (although it would suit me best because it has to stand on a Bosch washing machine), I took Electrolux because there was a good radius cashback. (this is not an advertisement for this brand)
And based on our drying processes so far, it has never been more than two hours. Returning to the towels, I have already put about 4 kg (weighing dry) several times, i.e. at least 8-10 not the smallest towels plus a few smaller things, all spun at 1000 revolutions and despite the fact that the cotton program shows 130 minutes, it has never lasted so long. The program was always shortened, as I remember correctly, to a maximum of 105-110 minutes, now I do not measure it anymore, because life goes on, and whether it dries 15 minutes longer or shorter does not matter to me.

And this is the optimal result for a PC dryer, similar times were obtained on the new Siemens IQ 500 with centrifugation at 1600 revolutions.

To clarify, my washing machine runs at 1000 rpm. Bought with the advice of the electrode https://www.elektroda.pl/rtvforum/topic3629334-30.html#18301397

I gained the data a long time ago from the Electrolux EDH3686GDE heat pump dryer - family 2 + 1.
I described more here: https://jackiewiczowie.blogspot.com/2017/02/suszarka-do-ubran-z-pompa-ciepa-zuzycie.html
Drying summary:
2016.12.22 - 2.13 kWh
2017.01.02 - 1.90 kWh
2017.01.10 - 2.12 kWh
2017.01.11 - 2.96 kWh
2017.01.18 - 1.85 kWh
2017.01.19 - 1.46 kWh
2017.01.25 - 1.49 kWh

It doesn't look good compared to my classic hair dryer: https://www.elektroda.pl/rtvforum/topic2918741-1050.html#20250121

Hello. I have read a lot on this topic.
I am thinking of a Bosch 8 series dryer.

Which model do you recommend?

I am also wondering which Bosch model to choose. But, rather, no one will advise a failure-free. And rather, take out a 5-year warranty

And what did you choose?
Nobody will tell you anything?

Seriously ? Almost 1100 posts and many other threads of this type on the forum. Reading for three days about dryers.

Bosch wtr87tw0pl is at a good price

Hello,

My choice preceded by reading the forum.
I considered all BOSCH models.

DRYER BOSCH WTG 86401PL series 6 (without heat pump) PRICE PLN 1785/12.2022

Energy consumption (ORNO wattmeter) per drying cycle, load from Bosch VarioPerfect Series 4.1000/1200 rpm washing machine:
1. 1.6 kWh / 1:06 h Prog. mix
2. 1.7 kWh / 1:08 h Prog. Cotton (towels)
3. 1.9kWh / 1:30h Prog. Mix (1.5 batches)
4. 1.7 kWh / 1:18 h Prog. Mix + delicate (1 mix load)
5. 1.1kWh / 0:51h Prog. Mix + gentle mix with (1 load)
6. 1.3kWh / 0:57h Prog. Mix + delicates (1 set of bed linen+blanket+clothes)
7. 1.5kWh / 1:05h Prog. Synt. extra for the wardrobe + delicate ( 1 load + blanket )

water condensation:
-From 1:1.8 liters (dia. 1.3 liters per load).

Characteristics:
- dries well
- sheds well (we have a dog, short-haired Chihuahua)
- heats the bathroom intensively
- louder than a washing machine
- can work on a current of 10 or 13 A

I RECOMMEND

For example, Lee LUKE jeans (2% elastane, 4% polyester 94% cotton) with a circle with a dot on the label, i.e. with a reduced drying temperature on the "Mix + Delicate" program are OK, they have not shrunk.

I have to correct my results that I presented in post #1080. The results showed very long drying time and low temperature. Over time, this time increased even more and I found that something was wrong with the dryer. I started following the threads on the electrode and there were not very optimistic messages about the need to dismantle the dryer and clean the exchanger, replace the heat pump, finish the refrigerant, etc. One remark, however, puzzled me - someone wrote that after cleaning the lint filter, the vacuum cleaner was practically unable to suck through air. I checked at home - after mechanical cleaning of the lint filter, I was practically unable to suck air through this filter. It turned out that mechanical dry lint removal is not enough - the filter may be empty and the air will not pass anyway - just some particles invisible to the naked eye clog it. The repair is very simple - clean the filter under running water as recommended by the manufacturer. After washing the filter properly (I even did it with soap and a delicate brush) the dryer works like new!
I decided to repeat the measurements, because the previous ones turned out to be completely unreliable and may mislead someone.
Initial load weight 4784g, final load 2960g (cupboard dry +2, i.e. very dry) - amount of evaporated water: 1824g.
Drying time: 1h26min (compared to the previous 3h52min)
The temperature during drying is about 40 degrees Celsius, the final temperature is 55 degrees Celsius (washing is completely dry), which is much higher than before.
Energy consumption 0.744kWh (compared to the previous 1.413kWh)
Efficiency: 0.408kWh per liter (kilogram) of evaporated water. It is worth comparing it with the heat of evaporation of water: 0.627 kWh/kg. In other words - hanging laundry on clotheslines will use more thermal energy than in a dryer with a heat pump.

Hello everyone. Question about BOSCH dryers. I cannot find information on the country of manufacture of the dryers. So far, I have bought several appliances made in Germany and now I also want to buy a MADE in Germany dryer. I am very happy with these appliances. I have selected two almost identical models, the designation is the same except for the symbol tip. One PL the other EU. Please give me a hint

Bosch continues to do business in Russia. Maybe they have factories there?

Global production, and the location of the assembly plant is not of the slightest importance.

I will share the info, because it's just a fun fact. Bosch and Siemens currently have only one dryer factory worldwide. It produces about 1.5 million of these devices per year. And it is located here - specifically in Łódź. Reportedly, the company is also working on launching production in China, but it is to go entirely to the Asian market.

Reading this topic you can come to a conclusion quite surprising to me: do not buy with a heat pump because it is not worth it and this dryer with a pump will quickly break down. I don't know if I drew good conclusions from this reading and I'm a bit in a quandary because it's time to finally buy a dryer.
I think the choice will fall on Bosch or Electrolux. That's why I'm going to ask if there is any big difference between the dryers of these manufacturers? It seems to me that they are the same technology and quality.
Despite the fact that most advise against the pump I am still considering it.
Dryer due to a small bathroom must stand in another room without the possibility of drainage therefore Let me ask if this can be a problem and whether in this case the better choice will be the one with a heat pump or without, or it does not matter. Thank you in advance for any hints.

I, too, after reading various forums, had a dilemma whether to buy or not but I bought a Siemens dryer in February this year and I do not regret it. Beautifully dries what you want and how much you want, as for shrinkage I think from two shirts something there slightly shrunk and so it's a fab. The dryer dries very quickly is always faster than the program shows and also I have a drain to the pail and water to gelask not only for me because there is a lot of it.
