Which fan to buy?

Hello all,
I've always had one of those little fans that attaches to the top corner of a door, and slowly moves warm air that rises out to the rest of the house. Mine is giving out and I'm wondering what to replace it with. Are these the best option, or is one of those "no power" ones that actually sits on the stove better? I'd like to get whatever does the most work, and gives the most heat to our home, obviously, with price being a distant second, within reason. I heard a comment that the REAL trick was putting a regular fan in such a way that it blows COLD air TOWARD the stove vs. the more typical like I described.

All thoughts appreciated! Thank you.

Yes, there are several threads here on the topic of Moving the Heat, which should actually be called moving the cold. Cold air is denser and easier to get moving. Once you do a convection loop gets established with warm air replacing the displaced cooler air.

Describe the floorplan and stove location or post a sketch of how the floor is laid out.

I like the Vornado fans. They blow the air in a tubular shape rather than am outward conical shape, thus giving you better control over where you want your heat directed. It doesnt just randomly disperse the warm air, it concentrates it better in a specific place.

The electric / stirling fans 'on' the stove are nice conversation pieces and can move a bit of air, but not really effective at 'whole house' circulation.

Hot air away from the stove / cold air toward the stove - thermodynamically its all about the same.

Draft wise, 'stuffing' cold air into the stove room can sometimes help - especially if the stove is in a basement, or otherwise below the neutral pressure plane, meaning natural draft is already an issue. However you also have to deal with the continual cold-air draft across the floor. Walking through it, setting in it, or otherwise occupying the floor of the space means you're in the chilly / breezy air. On the plus side, outlets are plentiful down low and as you mention, any old fan will generally do.

Hot air across the ceiling means a more diffuse cold air draft across the floor - which is generally more comfortable. All the fast moving air is up high - where people generally aren't. Also if you happen to get a bit of a breeze, then it's typically a warm(er) draft. But this method also generally means stringing fans, cords, brackets, etc up the walls and to the ceiling. I also ran into an issue with a bit of lint / dust build-up one year when I ran a fan blowing air across the ceiling.

So basically decide what you can live with and pick your poison!

I have a couple of heat - driven stove top fans. They do move some air, but I wouldn't say they move a whole lot of air. I like the way they look on the stove which is the main reason I use them. I have an older, more expensive one and a less expensive one that cost about $50. I just bought the inexpensive one and it seems to move more air than the higher priced one. The value may be a question of how long they last (the expensive one is 12 years old and still going strong).

If you need to move a lot of warm air away from the stove area, you probably will need to consider another method.
