Wood Stove Fan?

They can't move any more air than the natural air currents set up by heat rising, as I see it.
As stated, they are a novelty toy to watch and have satisfaction that there is heat rising from the stove. Clever advertising makes one think green, and lose sight of the physics. Maybe they are a bit phychic

The heat will rise straight up unless a powered fan redistributes the warm air to a location more desireable than above the stove.

Well fans are fitted to car radiators to get the heat from the radiator/engine into the air. With cars it cools the engine.

A fan on a stove gets the heat away from the stove and into the room in much the same way. It saves you money in some respects as otherwise the heat just lost of the flue.

You shouldn't have said "physics". This is not a silly fan that grabs the vertical air currents from the stove to crank a fan. This is a minitaure sterling heat engine. The sterling engine drives the fan with much more energy than can be gathered from the natural convection currents. The sterling engine steals heat from the stove's surface and dumps that heat to the ambient air through it's cooling fins.

There is no free lunch. This fan takes heat energy from the stove to make mechanical energy blowing air. I am too cheap to buy one but I can appreciate the way it works.

I have a small sterling fan on the diesel stove on the boat, in the confined area, works great, or I have to run the inverter to run a small 110V fan. It works great for that, but in the house, I think it would be would be of no value.

We have our pellet stove in one corner of our single level house, and just turn on the exaust fan in the master bathroom on the far other corner of the house, and the heat seams to flow all the way through the house.

ecofans are useless...they move zero air..cool in a novel kinda way..i found the sterling to be even more cool..but noisey..moved minimal ait..wish i had kept it tho..it was cool

Not a powerless fan, but we have a built in 110 fan in our lopi wood stove. It moves an amazing amount of air and spreads the heat much farther than the stove alone via convection.

Could you run an extension cord/110 line into the area, possibly under a wood trim strip or something?

Powered fans work so much better!
