Bosch/Siemens have come out with a new dryer on September first: the EcoLogixx 7 with heat pump. It uses 40 % less energy than what is required for A-class energy efficiency – so approx. 1.5 kWh for a full cycle.

It’s based upon their current line of dryers, sold under the Axxis name in the US. It’s got a 4 cu.ft. drum and all the regular cycles. It’s most interesting innovation is the self-cleaning condenser: during the drying cycle, water from the tank that collects the condensed water is flushed down through the condenser – up to four times during a drying cycle.

It retails for 1100 Euros -> USD 1500.

Here’s the link to a promotional video I copied from Bosch. It’s in German but I added a translation.

An oversized dehumidifier? Would the energy draw be all that less than a conventional vented electric dryer? How long to dry x pounds of y fabric that had been spun out at what speed?

It will be great to see if they can get enough people to spend the money and keep the technology alive.

Peter, we have Heat Pump hotwater tanks here now. They usually draw around 1200watts and have a recovery time to 60degC of around 2 hours for 300L. They now can operate down to temps of around -5degC which makes them suitable for most of Australia. It essentially runs a heat pump smaller than most window unit airconditioners. (2400watts)

Compared to the 4800watts resistance heat to achieve the same recovery, it uses a lot less energy.

And AEG (Electrolux)...

...have had one for years.

I must say, the self-cleaning condenser unit sounds a nice idea.

I should imagine that the current craze for energy efficiency and in light of high energy bills, has probably given manufacturers a bloody good kick up the backside, to get the latest energy-saving technology out to the consumer as quickly as possible.

I really hope they're a success.

Sounds like an interesting idea, especially for Europe where so many homes cannot have a vented dryer. Condenser dryers aren't a big draw in the United States, so wonder if they ever would be imported.

Come to think of it don't think there is a American condenser dryer, nor has there been one in quite some time. GM/Frigidaire had them, as did several other brands, even recall one in the home ec class room at school, but even then the teacher hated the thing because it forced her to use water during water shortages.

The differences are significant! But the technology is far more complicated, I'm worried that those dryers are more repair prone. I still wonder if it will pay for itself.

Miele has a see through drawing on it's website, here it is.

Askomiele, what is the model number of the Miele heatpumpdryer? I can't find any number on Miele's website.

"what is the model number of the Miele heatpumpdryer? I can't find any number on Miele's website."

I just tried to download it but it's not available... I'd be interested in the manual as well. According to the picture above - if you download the enlarged version - the model is: SOFTTRONIC T 8626 C WP. If you enter it into the search matrix it'll come up with the correct result but no link to download the manual.

Wow, for years there was only one heat pump dryer (AEG) on the marked and now we seem to become flooded by them. I still regret that gas dryers never made it as they are even more efficient. When I was ready for the Miele gas dryer it had just been discontinued :-(

Interesting thnks for posting this!

hmmmm I wonder if the air flow could be diverted temprarily/on demand to have a

1- vented dryer
2- room air conditioner

For the summer.

Win-wIn for those that can not hang laundry out.

I wonder if such dryers will be introduced in the US with matching American dryer capacity? Would these even need to be 220 volt machines?

Well, the AEG/Electrolux is 1350 watts, Blomberg 1200 watts, Bosch/Siemens says max. 2100 watts, V-Zug 1500 watts, Miele doesn't say. The V-Zug Unimatic is 2100 watts, too but requires 400 volts instead of 230. All but the AEG (6 amps) require 10 amps.

It's really great that the AEG and Blomberg dryers draw that little power, that means you can hook them up on one circuit. No extra investments for a new line for the dryer and still you can use the washer and the dryer at the same time.

Miele T 8627 WP

Today i' ve seen it in a store at 1749 € (that is 700 € more than BSH and AEG heat pump tumblers)
With that difference one can buy a BOL 1000 serie washer...

just noticed that in UK and IE euro-toploaders are rare.
Wonder why

Miele has the classical filtersystem, Bosch/Siemens has the selfcleaning condensor unit. Have no idea why, but I'm a big miele fan, still the Bosch Siemens is more interesting to me. When I go babysitting at a friends house, I always take a look at here condensor unit in her dryer. Every time it's not cleaned. So the bosch/siemens unit has an advantage upon the miele that it always works optimal. Or not?

Heatpump hot water in Oz?

Hi Brisnat,

What product is that? My dad was involved in that technology in the 80's, but I thought it had completely died.

There's a Japanese firm that's doing heat-pump drying too ... can't remember which one though ... so there seems to be a trend to look for more energy efficient methods.

Nick

Heat pumps do really work

Sometimes in summer I stay at a camping site in Slovenia (Trnovo ob Soçij, close to Kobarid). They have a 600 L. hot water tank run by an heat pump with a 0.8 KW motor. If resistors were used, they'd to have 8 KW power to have same performance.
They have it since a decade at least.
Here in Italy NOW we are ABOUT to begin this trend....

Self clean feature : how does it work ?

Periodical reverse blowing ?

AEG WP trockner came out on swiss market earlier than anywhere else, cause there were the ones by schulthess.ch and v-zug.ch . I bet the AEG WP is made by Therma

Well, as far as I know it was discontinued because of disappointing sales for this machine. Notwithstanding its obvious advantage in energy efficiency, people seemed to be put off by the higher price and the need for installing a gas supply to the machine.

Look at my YouTube videos. The dryer flushes the condensor with condensed water. It's the second and third video in my "Dryers" playlist.

Hi Nick,

It's Dux, Edwards, Saxon, Rheem, they all now have different flavours. I think it's from 2010 in Queensland where you wont be able to fit a Resistance heater for hot water into a new dwelling.

They're quite common now and after the rebates dont cost any more than a Resistance heater. The big advantage they have over solar, is that they are much cheaper to install in an existing dwelling.

Cheers

Nathan

Thanks, Nathan

You can tell I live in an apartment and have never bought a hot water service! I didn't realise heat pump technology had made it to market. Back in the 80's, it was a hard slog to get anybody to pay attention because fuel (gas) was cheap. It's good to see an idea that was initially ahead of its time finally gain acceptance.

Oh, okay!

Well, there's a pipe running from the water tank to the condensor (the front of it). Several times during the drying cycle, a little flap opens and lets the collected water run down the pipe and then through the condensor.

Zug

chestermikeuk's profile picture
That was the great feature I noticed with the V-Zug heat Pump dryer, no filter condenser to take out & clean, just a drop down door with an air clean filter sponge!!!

AND, a non vented dryer that doesnt sound like a train with all those blower fans!!!...

I do like the way the Siemens flushes the used water through, well thought out!!!, nice vids, Mike

"a little flap opens ..."

But surely there will be insufficient cleaning ability in this water? Won't you still have to periodically remove the condenser unit and blast water through it?

Speaking of driers, my Zanussi condenser just last week snapped its belt; new belt on order. Meanwhile I am using a small compact vented drier branded 'Electra' (Creda/Hotpoint machine by another name, before Indesit got its mitts on the companies).

I am shocked! The little vented drier dries admittedly a smaller load, but it does it in half the time! And the room is cooler too.

When the condenser machine finally does bite the dust, I'm tempted to go back to vented.

Mike, I do believe it....with such a price that makes miele best trade off price/performance *LOL*
Anyway - as I live quite close to the swiss border - I was told also Zug dishwashers are very reliable.

That's quite true, I had forgotten about that! The condenser drier is in the kitchen and the vented drier is actually in the spare room.

No, on second thoughts I'll stick with condenser driers LOL

I think the condensor is built into the machine - does not seem to be removable.

Alex : Thanks4expl - - - Nice design from the past

From the shining 70ies a knee-high HA TL tumble dryer with the matching washer. They were an early answer to the Reason DraWasher issue
It has a 100 litre drum -they said for 4 kg .. with today's trend it can hold 6 kg
For those who love top loaders but also want to bend anyway ;-)
Similar under table washers were made by Zanussi, A.E.G., Siemens .Even Miele made one (W473?)

Sometimes I wonder why some american consumers complain about the bending issue with FL washers while they have FL dryers.
I could understand it if they had BOTH TL W & D as the French have from ages...

Miele or Bosch/Siemens

Soon I will be in the market for a new dryer. In wintertime it's impossilbe to hang a complete load out to dry, so most of those things just go in the dryer. I'm convinced that heatingpumptechnologie is well made and very energy efficient. But I can't make up my mind neither to buy a bosch/siemens with selfcleaning condensor, and big filter gap where you can't get in to clean it or to pick up some coins that felt in. Or a Miele with filter on the door (still much more convenient to clean), but much more cleaning work with all the filters and still some chance to have lint in the condensor.
What do you think guys?

I have a feeling that Miele is very silent about there A+class dryer, in contradiction siemens and bosch make lot's of promo on their websites and on youtube(thanks to the one who set those videos on youtube)

Normally the only bending comes from unloading American dryers. Full sized domestic dryers for the USA market have always made a point of having very large door openings. One merely takes laundry from the washing machine and bungs it into the dryer, not much stooping required.
