Digi-Key has changed and it is not very good

That's changing now, thanks to heat pump dryers, which are vastly more energy efficient than traditional vented dryers. (And they're gentler on the clothes, since they don't heat the clothes up as hot.)

How do they work - are they basically a dehumidifier?

Yes, insofar as a dehumidifier is a heat pump operating with both the hot and cold sides in the same space. In a heat pump dryer, the hot side warms the air, which is passed through the clothes. The moist air then passes over the cold side, where the humidity condenses. The cold, dry air then passes over the hot side again to warm it back up to begin the cycle again.

My friend got one of those recently, he likes it, they're still very rare in the US though, he's the only person I know who has one. I'd heard of them before though, apparently they've been fairly common in Europe for a while.
SilverSolder:
They might save a lot of electricity. Would be interesting to see the numbers.
