Yes, We have vented our dryer with Hose on a couple occasions!! Once when our Heat Pump fuse went out, and we needed the heat until the guy could get here with the new fuse.... And seeing how well that worked, we did it again once, during a really cold dry spell, cause we WANTED some humidity and extra heat in the house!
Of course, this is NOT recommended as the usual mode of operation. And you may notice some increase in lint-dust... But, hey - go for it and break in that new dryer.
PS: The hose will clog up fairly quickly... Need to replace it or clean it out very often.
