This is a pretty slick fan......

I am probably the only one who will find this impressive due to the fact I help design and build Stirling Engines but thought it was worth throwing out there to see if any Hearth.com members have on of these things on their stove.


This is a brand new Free Breeze fan. These fans require no electricity, oil, gas, water or batteries to run, only a heat source such as a woodstove. They are approx. 22 inches high, 15 inches wide and 10 inches deep and weigh approx. 15 pounds. They spin approx. 200-300 rpm's and move approx. 150-200 cfm's on an average burning woodstove. They are great for your house, shed, workshop, cottage, hunting shack or snowmobile club. We have sold thousands of these fans worldwide with thousands of happy customers. Check out our feedback for the positive comments. If you have any questions or would like to see a short movie of the fan in action, please contact me.

Stirling fans have been around for awhile. The Heat wave and the Whisper fan are also stirling. There are a few thermal fan designs for stove. The Ecofan is thermo-electric. And for greater volume there is the Kettle fan.

Seems to me like they just did.

Certified doesn't work for them, he's just familiar with the technology and interested in the application. Rick

I too am on board to with Stirling engines. I made one last year and always think of how to make one for the top of the stove. I have a small candle-powered version. Youtube has some great videos on homemade fans. I have collected all sorts of parts to make a bigger version, but I think the noise would be a bit much. The base was going to be made from an old pot with a snug lid that would be JB welded once it is working.The rods would go up through brass sleeves to the crankshaft.

I do like the simplicty of the eco fan with few moving parts and silent operation.

Sorry didn't mean to confuse you. I have no affiliation at all with those fans I just found them interesting. Knowing the inherent nature of Stirling engines like I do I would never buy one for my stove (they cause me enough frustration every day so I don't want to look at one when I'm not at work ). If I was going to buy a non-electric fan it would be an eco fan. Much simpler design with far less to go wrong.

I have thought of a million ideas however by the time I get home from work I usually want to forget about them so they all get lost by the wayside :-S. If you think the one you were talking about would be noisy you should have heard the developmental one we fired up the other day at work I bet you could have heard it a block away! Lucky for me the ones I'm working with are super quite quiet and hopefully here in the next week we will find out which NASA mission they are being slotted for. We did build a really cool Stirling a while ago that was run off of solid fuel (we powered it with wood) however the company that we were developing it for lost interest. I really wish we could get somone on board with this stirling as the uses are astronomical and the fuel supply is pretty cheap. I say go for it and build the one you have the parts for it would at the very least be a cool accomplishment and discussion piece.
