Anyone hear of a 120V clothes dryer?

We are likely considerably above average consumers. Air conditioning is March thru October. Refrigerator, freezer, electric stove, at home 24/7/365, lots of computers running, etc. We use the washing machine much more than the dryer; each load gets followed by a "short wash" (with no detergent... to act as an extra rinse cycle as the HE detergent bothers our skin). It leaves the items pretty well "wrung out". And, everything needs to get *washed* but doesn't need to get *dried*. None of my clothes (T-shirts and bluejeans) get dried -- hang the shirts out of the washing machine (easier than folding them and putting them in drawers) and they'll be dry before the next load clears the wash. Bluejeans seem to shrink -- even when not actively dried. So, I hang them to dry and then put them on just before they are completely dried (to stretch them back out to their intended size). A few minutes on a warm body and in 80-120F weather makes short order of drying them! "Dress clothes" are going to get ironed so why dry before ironing? And, those are only used for social events and formal gatherings. Towels and bedding get dried -- though towels only partially (drying completely seems to cause uneven shrinkage, distorting them from their normal rectangular shapes). Trying to get bedding completely dry would be wasteful -- there's always a damp area as the sheets inevitably are tangled in the drier. So, leave the sheet untangled on the bed for a while before making the bed. Underwear and socks are the only items of mine that are completely dried -- because that's really the only way to get them to a state where they can be transferred into a drawer (I'm not going to *hang* socks and briefs!) SWMBO does a load of undergarments plus a load of her clothes -- most of which get dried. But, our climate is such that we have no thick blankets, no heavy clothes, etc. so everything dries very quickly.

With the singular exception of portable dehumidifiers, which are heat pumps but both sides are in the same box - the cooling side dries the air, and the heating side heats is back up. Net result including waste heat - warmer, drier, air. I'll add the pedantic note that the same amount of moisture in warmer air is a lower RELATIVE humidity (duh, if you think about it) so a pedant COULD claim that a heater makes the air "less humid" while not actually de-humidifying. To answer the original question - we had a 120v dryer in our first apartment; it was very small and took forever to dry anything. It was the first appliance against the wall when the revolution came.

You are likely one person? Laundry is just off the kitchen, here. No quarters. No special trips. No one poking through your unattended wash. You know when its "done" and can start the next load while you're cooking dinner, etc.

The so-called "compacts" and the "stackables" are all 120V operation, for reasons of portability and plug and play use. The interior volume is about half that of the full-sized 240V jobs. As for the full size dryers, the heater is the only 240V load, everything else, motor, timer and whatnots are all 120V operation, so the transition is not extreme.

Saving is not something US citizens seem to be concerned about...

Sure! We save *money* (that 300 euros of which you spoke). Would you say europeans aren't concerned about saving (money)?

Dehumidifiers are not heat pumps. They're more like air conditioners than anything else. Air is drawn through the 32o cooling coil to condense the moisture. From there it is blown through the condensor coil to bring it back up to its original temperature. This keeps net air temperature unchanged. Many of the central air/ heating systems have the same feature if selected by the user. They run the A/C for dehumidification and also the electtic backup heater to bring the air temperature back up to comfort levels. This is under thermostat control, and it only runs the backup heat this way when the air temperature is below the A/C setpoint.

Was gonna say, plan on 90 minute cycle times. That type of dryer is only for people who live in compact dwelling and have no alternative. Otherwise- no way.

Heat pump water heaters actually save a bundle.

not possible, the energy used to drive the dehumidifier (+ whats gained from condensing water) has to go somewhere
