Jonathan, it probably was a condenser dryer, this types of dryers does not work at all, they "works" condensing air with a condensor, the condensor is a kind of radiator and should be cooled by colder ar flowing inside of it, the moist air pass by the other side and the moist should be condensed on it and collected in a tray or took out by a hose in a bucket, in some modern stackable units like that the washer has an entry for that hose and a collector for the water, when is full the washer drain the water......
I owned just one condenser dryer in my life, it was given to me by a neighbor who was moving away, I hated it, it was in my garage, took 4-5 hours to "dry" a load!
It will never come out completely dry anyway!
So here is the answer to your question: yes you can but you'll never have a real dryer!
