Tomersun Wood Stove Fan Heat Powered 8-Blade Stove Fan, Fireplace Fan for Wood Burning Stove/Pellet/Log Burner, w/Stove Accessories Thermometer & Aroma Pod

Why I added a heat-powered fan to my stove

My wood stove has always produced plenty of heat, but getting that warmth out of the immediate hearth area and into the rest of the room has been a recurring challenge. Electric blowers help, but I prefer a simpler, quieter solution—especially during power outages. That’s what led me to the Tomersun 8-blade stove fan, a compact, heat-powered unit that sits directly on the stove and starts spinning as the stovetop heats up. After a season of use, I can say it does exactly what it’s designed to do: gently move heat off the stove and even out room temperatures, with zero wiring, zero batteries, and essentially zero maintenance.

Setup and design

Out of the box, setup is as straightforward as it gets: place the fan on a flat spot on your stove and let the heat do the rest. It’s light enough to move with one hand (when cool), yet feels sturdy and balanced on a cast iron or steel top. The eight-blade design is a nice middle ground—more vanes than traditional four- or six-blade models, which helps with low-speed airflow, but not so large that it hogs space on inserts with limited clearance.

The footprint is compact and the center of gravity feels right; once the stove is up to temperature, the fan stays planted and spins smoothly. It’s finished in black, which visually disappears on most stoves, and it doesn’t shout for attention. If you prefer your hearth clean and uncluttered, this fits in.

How it works (and what to expect)

This is a thermoelectric fan. It harvests the temperature difference between the hot base and the cooler top section to generate a small amount of electricity, which powers the motor. Practically, that means:

• It starts turning once the stove surface is warm enough, then speeds up as the stove gets hotter.
• There’s no on/off switch. Heat is the switch.
• Airflow is gentle by design—you won’t feel a “breeze” from across the room. Instead, it nudges the warm air off the stovetop and reduces stratification.

In my living area, the main difference is comfort consistency. Without the fan, the corner near the stove gets toasty while the opposite side stays stubbornly cool. With the fan running, temperatures even out, so I don’t end up roasting near the fire just to warm the far end of the room. In a small-to-medium space, one unit is plenty. In an open floor plan or long room, two fans—one on each side of the stovetop—can help push heat farther.

Performance and placement tips

Performance is highly dependent on where you set it. A few practical tips from my use:

• Place it toward the back or side of the stovetop where the surface gets hottest, but not so close to the stovepipe that you’re starved for cooler air over the top of the unit. The fan needs that temperature difference to generate power.
• Give it room in front of the blades so it can push air unimpeded into the room.
• Flat, solid surfaces are best. Enamelled or curved tops can make any fan feel less stable.

When I place the fan slightly back and angled toward the living area, it produces the most noticeable improvement. The eight-blade rotor seems to do well at lower RPMs, getting useful movement even before the stove is fully up to temp.

Included magnetic thermometer: surprisingly useful

The included magnetic surface thermometer turned out to be more than a throw-in. It gives you a quick visual on whether you’re in the ideal operating band and helps protect the fan (and your stove) from excessive heat. The dial highlights:

• Optimal fan/stove operating range: roughly 392–482°F
• Overheat warning: above 653°F (345°C)

I keep the thermometer on the stovetop itself; it’s meant to read the surface temperature, not the flue gas temperature. If I creep toward the upper limit during a hard burn, that’s my cue to throttle the air back or adjust fuel.

Aroma pod: optional, but pleasant

There’s a small aroma pod included for essential oils. A couple drops of something subtle (I like cedar or citrus) adds a hint of fragrance without turning the room into a spa. The pod warms up quickly; a light hand is best—overfilling just wastes oil and can get messy. It doesn’t affect performance either way, so think of it as a bonus.

Noise and maintenance

Noise is effectively a nonissue. At normal operating temperatures, the fan produces a soft, consistent whirr that fades into background room noise. If I hear any rattle, it’s been a sign that dust has built up on the blades. A quick wipe when the unit is cool brings it back to near-silent operation. There’s no lubrication needed and no consumables to replace.

Build and durability

The fan feels well made for its class. The blades are rigid enough not to flex under normal use, and the base hasn’t warped under heat. One practical note: the blades can be bent if the fan is knocked over or handled roughly when hot, so I let it cool before moving. As with most heat-powered fans, extremely high stovetop temps can shorten the life of the thermoelectric module. That’s where the thermometer helps—stay within the recommended band and you should be fine.

Limitations to be aware of

• It’s a heat circulator, not a blower. If you need a strong stream of air across a large room or down a hallway, an electric blower is still the right tool.
• Startup depends on stove temperature. If you run a very low, slow burn, it may spin slowly and move less air.
• Flat placement matters. On very small or curved surfaces, finding a stable spot can be fiddly.
• As with any small appliance, shipping knocks can happen; check that the blades spin freely and the unit sits flat when you first unbox it.

Who will benefit most

• Wood, pellet, and log stove users who want to even out temperatures without adding electrical noise or complexity.
• Off-grid cabins or homes in outage-prone areas where a passive solution is valuable.
• Small-to-medium rooms that feel hot near the stove and cool at the edges.
• Households looking for a quiet, set-and-forget accessory that complements, rather than replaces, a primary heating setup.

Practical usage routine

Here’s how I work it into daily burns:

1. Start the fire and let the stovetop come up to temperature.
2. Position the fan at the rear third of the stove, angled toward the room.
3. Check the thermometer—once it’s in the 392–482°F band, airflow is at its most useful.
4. If I need more reach, I add a second fan on the opposite side pointing the same direction.
5. After the fire, I leave the fan in place to coast down. I only move it when fully cool.

This routine has become automatic and requires almost no thought once you’ve dialed in your placement.

Alternatives and comparisons

I’ve used four- and six-blade models in the past. The eight-blade design here doesn’t transform the category, but it does seem to produce more usable airflow at lower speeds and temperatures. In practice, that means the room starts feeling balanced a bit earlier in the burn cycle. If you already have a working stove fan, this isn’t a mandatory upgrade; if you’re buying your first, the extra blades are a sensible choice for a modest bump in effectiveness without added complexity.

The bottom line

The Tomersun 8-blade stove fan delivers exactly what a heat-powered fan should: quiet, electricity-free circulation that smooths out the hotspots and cold corners around a stove. It’s simple to use, compact on the stovetop, and the included magnetic thermometer is genuinely helpful for hitting the sweet spot and protecting the unit from excessive heat. The aroma pod is a small perk, and maintenance is essentially wiping dust off the blades now and then.

It won’t replace an electric blower for moving air long distances, and it’s not meant to. But if your goal is to make a wood or pellet stove feel more comfortable and efficient in the room it occupies, this fan is a smart, unobtrusive addition.

Recommendation: I recommend it for anyone running a wood, pellet, or log-burning stove who wants a quiet, passive way to improve heat distribution without adding cords, noise, or complexity. It shines in small to medium spaces, pairs well with outage preparedness, and rewards good stove operation with a more evenly heated home. If you’re expecting a gusty fan effect across a large open plan, look to an electric blower; for everything else, this is a dependable and thoughtfully designed accessory.
