Was just wondering what kind of fans you guys use to move heat around your house?
ThAnk you.
 
Cheap fan that we've had for years . . . probably bought at Walmart, Kmart, etc. . . . just a regular, ol' 10 or 12-inch fan with three speeds that most normal people would set on a table and cool themselves off with in the summer . . . I think we use it more during the winter.
 
Same here, just a regular 12" table fan run on low speed.
 
I like the vornado and the corner door frame mounted entree air(sp?). The key for me is to blow cold air low towards the stove in order to facilitate a bit of natural convection.

Yes, a table fan (or small vornado) set on low speed. Place the fan in a hallway or room that you want heated and blow the cool air towards the stove room.

I too have the vornado fan and like it. We actually use two fans a lot. One near the stove and one blowing towards the stove. Yes, they are at different levels. The one near the stove blows the higher air and the one blowing towards the stove blows the lower air.
 
I just got 2 of these. I have them mounted directly to the bottom of the transom to blow the hot air towards the back of the house which works great.

I have a black Honeywell fan (see pic) that looks exactly the same as these except these are a LOT quieter. My woodstove room stays around 74 and the back of the house stays around 70. For context: My house is 1300sq ft, uninsulated brick ranch, 3 bedroom, single level, old drafty windows, Colorado front range climate, wood stove located on one end of home

Here's where one of my fans are mounted except I just replaced the black one for a white one. The other is towards the back of the house to blow air in the bedrooms. I think having the fan closer to the cealing is more effective than a fan at ground level due to transoms (top of a door way). These create the greatest barrier for hot air and you can either remove them or install a fan to move air under them as I did or install a fan within the transom itself which would be nice. Cold air can flow freely throughout the house because there are no barriers, like a transom, at the floor level which is why I chose to mount higher up. If you were to flip your home upside down, and have the transoms at the floor level and not at the cealing level then a floor level fan would make more sense. The temperature of my home with fans placed where they are at versus without fans turned on supports this as does this: http://www.woodheat.org/planning/heatdist.htm

I got a fan mounted on the box of my Blaze King, the thing is noisy but sure moves the air around. I only use it to warm up the house on a real cold morning. I also run a eco-fan they claim 100cfm I don't think there that good but any movement is better then no movement. I want to try Free Breeze fans. They look really good. http://www2.cyg.net/~freebreeze/features.htm
 
I use the Eco-fan, 3 blade. I have my Defiant in the basement, in a corner open room 6 x 8. The fan will keep the back of the room 20 degrees cooler than the area in the open part of the basement near the stove. My entire Cape is heated by this stove alone. The fan just keeps the hot air moving enough to create a constant rotation of air. So far, it was worth every penny of the 135 I paid.
 
I have a large, high-velocity commercial fan directed at the 1/2 cord interior wood stack that sits directly opposite my stove face. I have it on low most of the time, but as the wood dries out, I turn it to medium to keep the drying rate up. It sends a remarkable amount of humidified air directly through the spaces between the splits and helps move the air away from the stove at the same time. Helps the wood dry out super fast as well.

Interesting thing is how uniformly diffused the air is. Even though the fan is on the floor and directed at an upward angle, some air seems to come through just about every space between the splits. Strange feeling getting my face roasted while my butt is getting a cool, moist breeze while I'm working at the stove.

I also have a 1100 CFM overhead air filtration unit that is on most of the time I'm down in the wood shop. Obviously, it was put there for a different function, but I get dual use from it while it is running. It is pretty effective at moving the air that would otherwise stagnate between the floor joists in the basement. In spite of both of these fans running, the corner where the stove is situated is always at least 8-10º warmer than the opposite corner of the basement. Most of that has to do with the heat rising up the stairwell before it has a chance to get to the far side of the basement.
 
i installed my stove under a 2 piece air conditioner so i can turn on the fan only option and really get some serious air movement but its kind of noisy i like the free breeze idea using a stirling engine a company called gyroscope also sells a stirling engine fan i would love to hear if anyone has experience with these
 
I have a duct fan and a short bit of ducting installed in my "transom" above the stove room passageway, it blows the hot air down and through another passageway. This has been very effective for getting the heat trapped up in the 10 ft ceiling of the stove room out and up the stairwell to the second floor and to the rest of the house.

Out of curiosity I tried a fan on the floor in that passageway blowing the opposite direction (towards the stove), but no way was it pumping the heat out of the stove room anything like the duct fan does, plus having the fan sitting right in the passageway where everyone walks was a bit of pain in the butt.
If we have the fire going in mellower weather we often have to keep the duct fan off because the upstairs actually gets too warm.
