You know, maybe... another take on this...

You can install a small fart fan on the top, then have the duct run down to the bottom of the room.
Same idea... just, complicating things a little bit more.

Mr. Blue, as Rusty Trichome said, try and do a "dry run".
That will help you nail down the temps.
turtle420 Reviewed by turtle420 on . Quick Question.. I live in ontario, and i am moving into a new house with a work shop at the back of the house. i plan on puttin my cab unit bak there but i am worried about the temp issue. this room isnt heated and it is a cold room. would running a "sealed room": where i scrub the air, then exchaust it back to the cab. save enough heat so i wouldnt need to run a heating unit? i have never ran a sealed room so i have no idea if this would work.
