'Prius of Dryers' Worth Checking Out New heat-pump technology can cut costs in half, says reviewer By John Johnson, Newser Staff Posted Oct 25, 2014 12:02 PM CDT 17 comments Comments It's expensive, but more efficient. (Whirlpool) (Newser) – No more vents for clothes dryers? That seems to be the promise of a new class of high-efficiency dryers hitting the market. Whirlpool, for example, is out with a new model that has Matthew Zahnzinger jazzed at Reviewed.com: "It's no understatement to say the Whirlpool Duet WED99HEDW ... is the most exciting dryer to hit the market in decades." The trick is that the machine has a heat pump that recirculates hot air instead of venting it outside. The technology could cut the price of drying clothes in half, with the added bonus of treating clothes more gently, writes Zahnzinger. This, of course, comes at a price, specifically $1,595, but it's possible that utility companies will defray that with rebates. LG will have a model out later this year, and the website is holding off on a score until it can compare the two. But for now Zahnzinger says the new technology is definitely worth a look, especially for those already energy conscious. (Its headline calls the Whirlpool the "Prius of dryers.") That these dryers don't need vents is also of note to Appliance Magazine, because it means that homeowners would be free to put them "virtually anywhere."
