We're moving our washer/dryer out of our basement as part of a bathroom remodel. Existing washer is top-load, so not stackable, and I've never liked it (came with the house.) So, I'm treating myself to a new set. (And, not even feeling guilty, because a good friend wants my set!) Have any of you had experience with ventless/heat pump dryers? Or the all-in-one washer/dryers that also use a heat pump? They're not super common in the US, but I'm intrigued by the technology.
