Has anyone tried these for moving air ?

http://tinyurl.com/7tdd84m also found this one http://tinyurl.com/85ov9zy has pretty good reviews. i need to push some heat into my bedroom and figure i would mount one of these under the door frame. I am currently using a fan on the floor to push cold air out But i need some heat !
 
I have one in the bedroom doorway. It's ok. Usually turn it on when I get up in the am and by the time I'm ready for a shower, it is a bit warmer in the master bath.
I don't let it run when I'm not home. Don't trust it, like the box fans.
 
We had to install our stove (XXV) in a non-ideal location, and the installer suggested we may benefit from a fan like that.

I have a fairly open floor plan, but, so far, my stove is heating a good chunk of my 3,000 SF house. Definitely the downstairs, and, with the right doors closed, the upstairs, too (just a few degrees colder). I can't imagine the little fans would make anything more than an incidental difference.
 
I used the Suncourt Entreeair fan (45* angle corner fan) and the Minuteman model (2nd link that smoke posted). Used these until I installed through the wall fans (Broan 512) this year.

The doorway fans dont do a bad job. I personally liked the little square one from Northlineexpress. It came with 2 mounting plates, so the fan was more versatile and it had the High/Low selection.

Thing I didnt like about them. They say they are rated for 90 CFM. The through the wall fans are rated at 90 CFM also and they will blow your hat off. Where the corner fans seem to be maybe 20 CFM in reality.

They do work and they do move air. Kept us warm the first few years. The through the wall fans are just a noisy, but move much more air and keep the temp almost dead even.
 
I use two of those corner fans all winter long. With the layout o f my house half of it would be like 8o degrees and the rest was around 65 until I purchased them. N ow the house is fairly consistent.

Did you notice a big difference in heat distribution between the through-wall and door way fan? I've got a door fan and I'm considering a through wall model.

The temperature difference is about the same. Might be a tad bit warmer. But the greatest benefit from going from the corner to the through the wall, is being able to close the doors at night.

The cold air return for the house is one giant return. So the rooms have pretty large gaps under the doors ( 1.5" ). So when the fan pushes air into the room, the cooler air is pushed out through the bottom of the door.

The kids doors are shut now also. Always had to keep them open before.

Closed doors = more privacy
 
I have a couple of the wedge shaped ones. They are ok. I have had one burn out and another one lose a bearing. They aren't great quality.

The natural airflow doesn't seem to include my bedroom, so I still have one to push some air in there, assuming it all doesn't escape up my giant stairwell.

On another note, the best thing that I have found for circulations sake is a table fan. I have found that is is much easier to move the cold, dense air along the floor than it is to move the warm air around the ceilings. I have one 12" table fan that blows cold air back towards the stove and it seems to be pretty effective at moving the air around.
 
Thanks guys for all the replies and help/ideas I dont need a ton of heat in there as i dont like it hot for sleeping but i could use a little. I think one of these could solve my problem from your replies. Once i get this dialed in i think im gonna be golden. I dont have a problem putting in thru wall's but i dont want to experiment with them first and making bad decision/positioning by cutting holes in the wall. will research the ones posted and pick one :)
 
I have two similar fans. They may help a little, but for the most part I think they are eye candy.

I have 2 of the entree air in the doorway to my kitchen. Does a little bit of good to move some air. I also have a thru the wall fan. It is halfway up my stairs on the floor of a bed room. Works great getting heat into the bedroom. Same temp as where the stove is. Unfortunately the heat doesn't travel much further down the hallway upstairs. As soon as you walk halfway down the staircase the heat justs hits you. it seems to be trapped.
 
have one of the corner fans in the hallway located about 23ft from the stove and the hallway is 27ft long, if the stove is set for 70 believe it or not my bedroom goes up to 68 it also helps that the stove is lined up to shoot down the hallway ,ask me again in feb if its still this good
 
I've never used either model, but have read numerous reports that the Entreeair fans are fairly noisy.
 
The entreeair is relatively noisy for the amount of air that it moves. If it moved twice as much air for the same noise, I would be a lot happier. We had one in the door casing to the living room last season and had to shut it off when we were watching TV. It was easily noisier than the blower on my P68 at 1/2 to 3/4 speed.
 
i'm actually getting amazing results with this little personal desk fan i had lying around-

it's nice that the spot i need it is unobtrusive. the dining area fills with warm air easily. and it collects at the ceiling. but the arch between there and the kitchen, and the two arches and narrow entry to the back bedroom keep the heat from progressing very well.

we have thermometers in the kitchen and the back bedroom too.
and after just ten or fifteen minutes of first putting the fan there, i could see a marked improvement.
it's quiet too.
i also have a vornado humidifier in the living room w/ the stove. that circulates extremely well and collects the heat from a hot spot there and rolls it out under the lintels to all the adjacent rooms.

they had the corner fans at home depot so i grabbed 2 . ill try 1 for now see what happens
 
This is what i have going on right now. http://i43.tinypic.com/6eer9v.jpg
had it like that for an hour or so. I just shut the bottom fan pushing cold air out off. I was thinking the fan on the bottom might be pulling down the hot air being pushed in from the top right back out , and defeating the purpose
Temp outside is not bad about 48 so hard to compare it to last nights 29 degrees
Notice the Header above the door, i guess thats whats stopping my air flow its a good 12 to 16 inches

edit.. wow sorry about the size of photo i just used a tinypic url
 
I have a couple Entree air fans also, but find that a small floor fan blowing the cold air near the floor into the heated room seems to even out the room temperature differential better than the corner fans do by pulling the warmer air near the ceiling in to replace the colder air being pushed out of the room. Probably depends as much on your floor plan and convective air flow pattern as anything.

its a long journey up to that bedroom door for the heat to travel, but i can get it 70 right at that doorway as my thermostat for my furnace is mounted there and i can get it to about 1 to 3 degrees from downstairs, sometimes they are actually even so i just have to get it thru the door
 
A good night of chimmichangas and some bean burritos, and I can move more air than any corner mounted fan that you can buy!
 
I set this fan on top of my hopper pointed up at about 45 degrees. I tried it today for the first time. I raised the upstairs temp by 4 degrees by moving the air. I actually had to lower the heat setting. try it.
