Yes washman, Bosch/Siemens Home Appliances is selling a washer that can wash up to 6.5 hours. Of course, you'll have to select a special cycle and press the ecoPerfect button to get it to wash that long and to achieve the energy savings that are promised on the big green sticker on the washer's front - but as long as people are only looking at the energy label and buy whatever uses the least energy that's what will be bought. I remember when I worked for Europe's biggest retailer of electronics: so many people would walk through the aisle with a piece of paper and actually note down the exact energy usage of an appliance. It was like they were obsessed with it. Sure, some would come up to me and ask for my advice but most didn't care.
We'll see where things are going. Recently, even Miele, a brand typically known for no-nonsense appliances, has added self-cleaning cycles to their washers and even dishwashers along with a warning in the manual against the too frequent use of the low-temp Eco cycle.
Oh well, I realize this is turning into a "The limited usefulness of the EU energy label" argument so I shall stop here.
Heat-pump dryer, eh? I don't have one, don't want one - unless I could embrace the idea of abandoning my one laundry day in exchange for doing laundry several days in a row or during the night.
