Well here is version number 1 of my home made door fan, an old (from a dead computer) 12 v muffin fan and a simple over the door hook, if it works I will look into some bigger fans and make my own mounting bracket

Sometimes the simplest answer is the best. I was looking into using a 110v muffin fan, but I knew my wife would be upset if I put holes in the wall/trim. I didn't think of the over the door bracket. Let us know how it does please. Thanks.
 
Pretty much looks like my set up, only I attached mine to the door jamb.
You can find all the parts for them here:

Cygnus,

Which model (cfm) did you get? If you had to buy again, would you get the same one?
 
It is in a room with 2 doors, one fan blowing in (down low) one out (the muffin up high) as I said it is from an old dead computer so I have no idea on size/ model.
 
Nice job on the bracket!
That is a good idea to use with the fan below.
I don't have any old fans kicking around.
We are still in the planning stage!
May have to do 4 rooms. Not cold enough yet to know.

Has anyone seen these?? 120 CFM
Price is comparable to a new computer fan but will require holes in the door frame or use the bracket design above!!.

I have two 105 cfm fans. They haven't failed me yet and as sawdustburners stated, blow the cold air towards the stove.

Yes, I would buy them again. They're pretty much quiet and increase the heat in my hard to get to rooms.

I used to have that type of fan. It's sounds like you have a Cessna in your living room, very, very LOUD!

Thanks for the info!
Looks like computer fans might be the way to go.
 
Here is a link to some fans.
Check out this one: 92940 ARCTIC KEST-471BT 112 CFM $16.75

If you dont want to drill holes use some of that sticky velcro, and remove itin the off season. Thats what I am using. The magic sponge removes any residue left from the sticky side.
