i see a metal exhaust pipe so its a 78% efficient unit. Hmmm.... i don't see dampers. Keep taking pictures of the ducts until we see something like a wingnut or a handle sticking off the side.
Also, i forgot to mention if you don't care about looks you can take the registers off the vents on the down stairs and it will have a similar effect.
