Here is an interesting concept. These have existed in Scandinavia for decades. My understanding is that tumble (automatic) dryers there are finally taking over!
What the manufacturer is not saying BTW, is that a USA dryer takes about 2.5 KWH as well for a load. (Mutilply by your electrical rate to see what a load costs you).
Assuming a 5,000 watt element running for an hour (and ignoring the negligible motor draw) we can imply that the element is energized for about half the time, hence 2.5 KWH.
The heater in a dryer works almost constantly towards the beginning of the cycle and then tapers off. The latent heat of vaporization (changing liquid water to a vapor absorbs a huge amount of heat in doing so, and lowers the temperture in the drum; as the clothes become more dry the drum is cooled less and cooled slower, hence the heater goes off more frequenlty and stays off longer as the cycle progresses.
Thermostatic auto-dry (not the electronic auto-dry) is based on this principle as well. When the heater is *OFF* the timer advances. We can see then, that the timer advances more, and for longer periods, as the clothes dry.
If you get a chance, check out Staber's washers too. IIRC the dryer is a rebadged Whirlpool.
