Best Heat Powered Wood Stove Fans for Even Heat
A wood stove makes a pocket of intense heat right around it while the far side of the room stays cool. A heat powered stove fan fixes that without a cord or batteries.
These fans use a thermoelectric module that turns the temperature difference between the stove top and the fan's cooling fins into electricity. The hotter the stove, the faster they spin.
We picked fans with solid track records, including the original Canadian made Ecofan, plus a stove thermometer so you know when the stove is running in the right range.
Best Overall: Caframo Ecofan 812 AirMax
Caframo's Ecofan line started the stove fan category, and the AirMax is its most popular model. It moves a lot of air at moderate stove temperatures and runs nearly silent.
It is made in Canada and backed by a two year warranty, and it holds up for years where cheaper fans warp or fail.
It works on wood, pellet, and gas stoves with a flat top surface.

Shop on Amazon →Best for Low Stove Temperatures: Caframo Ecofan UltrAir
The UltrAir starts spinning at lower stove top temperatures than most fans, which is helpful for smaller stoves, pellet stoves, or long low burns overnight.
It is built to the same quality as the AirMax and is a good pick for anyone who runs a stove at a gentle simmer.
Like other Ecofans, it has a bimetal spring that tilts the fan up if the stove gets too hot, protecting the motor.

Shop on Amazon →Best Value: VODA Heat Powered Stove Fan
VODA's four blade stove fan is a popular low cost alternative. It moves a good amount of air for the price and includes a magnetic stove thermometer.
The build is lighter than an Ecofan, so do not let the stove top overheat, but for occasional use it is a solid buy.
It is a good gift pick for anyone who just added a wood stove to a cabin or garage.

Shop on Amazon →Must Have Add On: Rutland Magnetic Stove Thermometer
A stove thermometer tells you when the stove is in its efficient burn range and when it is getting too hot, which protects both the stove and the fan.
Rutland's magnetic thermometer sticks to a single wall stove pipe or stove top and is color coded for creosote, best burn, and overheat zones.
It is a small purchase that helps you burn cleaner and use less wood.

Do heat powered stove fans really work?
Yes. They do not add heat, but they spread the heat a stove already makes into the room so it feels more even.
Do stove fans need electricity?
No. A thermoelectric module turns stove heat into the small amount of power the motor needs.
Can I use a stove fan on a pellet or gas stove?
Yes, as long as the stove has a flat top that reaches the fan's minimum operating temperature.
Why is my stove fan not spinning?
The stove may be too cool, the room may be too warm, or the fan may have tilted up from overheating. Let it cool and try again.
Tips for Getting the Most from a Stove Fan
- Place it at the back corner. Set the fan toward the back of the stove top, away from the flue pipe, so it pushes air out into the room.
- Do not overheat it. Most fans are rated to about 650 F at the base. Check with a stove thermometer.
- Keep the fins cool. Fans spin faster when the room is cooler, so they work best when the fins get room temperature air.
- Clean the chimney. A clean flue burns hotter and safer, which also helps the fan.
