Transferring Heat

I was thinking of putting one or two small floor register's 4"x10" a nice decorative one for my wife on the wall above where my stove is located to distribute heat better to the bedroom would this work?. I'm using a door fan which helps but I thought by putting one or two register's on the wall it would work better to push some of that heat into the bedroom . Maybe even adding a small doorway fan in the register would work.

I just bought the hard wired model Thanks for the info.. Has anyone used these at all. I'm just hoping it works its a pretty good size unit as far as the hole its going to put in the wall finding out it doesn't work after the fact will suck i don't want to patch my walls up. I haven't been able to find any reviews on this model so maybe someone here has used one.
