What powers your DC ceiling fans? Solar, wind...?
Ac... you just plug them in.. the power on low is much lower than an ordinary ac fan, 3 Watts in place of 30.. they have inverters inside

A little pricy.. I got mine on ebay, refurbished..panama by the Casablanca fan company... home depot also caries them, at ~twice the price
Most of those stovetop fans aren't actually heat powered. There's a TEG module generating electricity to run a little electric fan motor.
The exception would be the ones that have sterling engines, which really are heat powered.
Love mine , not sure about effeciency claim tho.
Yup, my ceiling fan runs near non-stop all winter long but I run mine in reverse so I don’t feel a draft from it. Up in the winter, down in the summer.Running our ceiling fan makes a big difference in heat output and efficiency (burning less wood) compared to not using the ceiling fan. The ceiling fan is in the center of our living room, pushing the air down, and the stove is in the corner of the living room.
We tend to lose power every winter, so I considered a heat powered fan to use during those power outages. Whether or not it will make a difference has yet to be seen.
I had no idea that they had a safe operating range. The label says that damage to the fan/stove can occur if operated outside those temperatures.
There's a spot in the top middle of my insert, just in front of the flue outlet, where the actual stove top is exposed (convective jacket just goes over the left and right sides of the top)and I've thought about getting one of these and putting it on there...then cutting a decent slit through the sheet metal part of the surround to let the air out. Figured this would help get the heat out that is normally trapped behind the surround.
I know they say not to put these fans right in front of the stove pipe....supposed to have cooler air behind them, but do they still work at all if placed right in front of the pipe?? ( say a couple inches of clearance)
This is genius.
Not sure how well that would work for you. I'm pretty sure I read that the cooler air it pulls from behind the stove is what helps it run. Maybe check out the different manufacturers web sites and compare the different models. I know the air behind my stove isn't exactly "cool". I have a fairly narrow stove, cornered between two windows, so I put the fan on the back corner of the stove. The left edge of the stove top is at the left edge of the picture.

The TEG needs a certain temperature differential between its hot side and its cold side to make power (varies by module). The big metal heat sink that is the fan's body is designed to provide this. The hot side of the TEG module faces down towards the stove, and the cool side is heatsinked behind the fan.
Further reading, if you're interested (more detail is available in individual product datasheets- this module might be used in some stovetop fans, although that particular module would probably do better on the back corner of the stove!)
For how long do you have it and which blaze king do you have? I am wondering if it would work on the Ashford 30 and which fan would work best for my stove
