Now that you’ve had your wood-burning stove installed and running for a few weeks, you may have noticed cold spots in your room. During your research, you may have come across stove fans—or perhaps a friend has recommended one as a way to distribute heat more evenly around your home. We’ve been in the stove fan business for several years and can help answer some of the most common questions:
Which is the right model?
Do I really need a stove fan?
Is there a fan for inset wood-burning stoves?
What about low-temperature stoves?
Which stove fan is best for the size of my room?
Are they ugly monstrosities?
And, of course – do they actually work?
We’ve been asked this question thousands of times via our online chat and over the phone. Because heating stoves come in so many different types and settings, there isn’t a one-size-fits-all answer.
First, consider the size of your room. Is it an open-plan space that you’d like to heat evenly? If so, the most powerful stove fans are Stirling engine models such as the Vulcan, Warpfive, or Zephyr—all of which are handmade in Europe (two in the UK, and the latter in Ireland).
The Vulcan was the first Stirling-engine stove fan on the market, and for many years it was the only option available. It quickly built a loyal customer base, impressing users with the ingenious 19th-century invention of Dr. Robert Stirling, repurposed to circulate heat efficiently around the room. Because the design proved so successful, only minor improvements have been made since its release, such as refinements to the blade shape. Later, the Vulcan Mini was introduced to meet demand for a smaller unit. Like all Stirling stove fans, the Vulcan comes with a 3-year warranty—a significant upgrade compared to most Peltier-powered fans. Interestingly, the competing Stirling fan brand Warpfive originally launched with a lifetime warranty, but later revised this to the industry-standard 3 years.
Warpfive fans are engineering powerhouses. With their large blades and high-temperature operation, they generate enough energy to push impressive volumes of air—the manufacturer even claims the airflow can be felt up to five meters away. The Stirling models are generally quite large, but for those with a smaller space above the stove, the Warpfive Sidewinder offers a compact solution at just 225mm tall. Its fan blades sit on a platform above the miniature Stirling engine, driven by a belt system that transfers energy from the stove top. Combined with its graphite piston, borosilicate cylinder, and contrasting brass screws and counterbalances, the Sidewinder is as much a piece of mechanical art as it is a functional heat distributor.
Among the elite Stirling-engine stove fans, the Zephyr stands out as a modern, precision-engineered newcomer that blends performance with minimalist aesthetics. Designed and manufactured in the EU with sleek, industrial-modern styling, Zephyr delivers whisper-quiet, efficient heat circulation without requiring electricity or batteries. More than just a heat distributor, it’s engineered for durability—built with premium materials that ensure long-term reliability and noticeable fuel savings. Its craftsmanship is captivating: each component reflects careful attention to detail, making the Zephyr as much a visual statement as it is a functional appliance. Plus, with a 3-year manufacturer’s warranty, it offers reassurance and value for those seeking high-performance elegance in home heating.
If you’re not especially technically inclined, you might want to consider the largest—and probably the most powerful—Peltier-powered stove fan from Valiant: the Vanquish 250. Introduced to the market in 2016, it stands 250mm tall and features two aerodynamically profiled blades designed to push large volumes of heat, making it particularly well-suited for large rooms.
The vast majority of stove fans you’ll encounter when beginning your research are designed to work in a standard room of around 200 square feet or less. Of course, Stirling-powered stove fans (like those mentioned above) can be used to eliminate cold spots in such rooms, but in many cases smaller Peltier-powered fans will do the job just as well. They can even be used to direct warmth through an open doorway and up the stairs, so that bedrooms benefit from the stove’s heat too. We’ve tested this ourselves and can confirm it works fine—provided it’s not one of those cold, windy, and miserable days, and you keep the bedroom doors open!
If you want to warm a standard-sized room with a stove that doesn’t reach temperatures above 350°C, you should consider models like the Valiant Premium, Ventum 3, or SuperFast. If you’re unsure of your stove’s maximum temperature, it’s worth buying a stove thermometer. This inexpensive device not only helps protect your fan but also gives you a clearer idea of your stove’s optimal operating range.
Valiant stove fans are powerful, silent, reliable, and backed by a 2-year warranty. The Ventum 3 is an evolution of the Premium: it starts operating at a lower temperature and spins faster thanks to its lighter blades. Despite this, the Premium remains the most popular model in Valiant’s range.
Another UK-based manufacturer, The Stove Fan Company, specialises in heat-powered fans such as the mid-level SuperFast Mini, or their flagship Viking models (Advanced and Mini), which even incorporate innovative features like a built-in fragrance dispenser.
Most modern Peltier fans also feature a bimetallic strip in the base, which tilts the fan to protect the Peltier module from overheating. However, even with this protection, they cannot withstand very high stove-top temperatures and must be removed if the surface exceeds 350°C. This is another clear advantage of Stirling-engine fans, which can safely operate at temperatures of up to 450°C.
What if my stove doesn’t have a flat surface?
The design team at Valiant recognised that with so many different wood stove designs now available, there was a need for a more versatile fan. Listening to customer feedback, they developed the first heat-powered stove fan that attaches directly to the flue pipe. Building on the success of their hugely popular Premium 4 stove-top fan, they removed the base that normally sits on the stove and replaced it with a clever magnetic attachment called “wings.” This innovation gave rise to the Remora.
The Remora produces an excellent airflow while remaining quiet enough not to disturb daily activities. With its durable satin-black anodised finish, it looks just as stylish as Valiant’s previous models. It is designed to work with all magnetically attractive flue pipes and fits most diameters between 10–17cm. Measuring 200mm high, 180mm wide, and 120mm deep (from blade to flue), and weighing only 770g, it is impressively lightweight.
Attaching the Remora is simple: fold back the magnetic wings, position the fan on the flue pipe, and gently return the wings to grip securely around the pipe. Take care not to let the magnets snap shut too quickly, as this could cause damage. For safety, the fan must be positioned at least 20cm above the stove top to ensure blade clearance and prevent overheating of the motor. The powerful magnets are capable of holding the fan securely even at temperatures exceeding 400°C.
This makes the Remora an ideal solution for stoves that do not generate significant heat at the stove top—such as soapstone stoves—since it harnesses energy directly from the hottest part of the system: the flue. It’s also a practical choice for stoves with decorative tops, or those with uneven surfaces where a traditional stove-top fan cannot sit securely.
There are hundreds, if not thousands, of gas, wood, and multi-fuel stove brands and models on the market today. This allows customers to choose a stove that not only meets their heating requirements but also fits their unique circumstances—such as building construction, chimney setup, or the size and shape of the recess where the stove needs to be installed. Stove fan manufacturers follow very similar considerations when designing their models.
For a long time, owners of built-in stoves were excluded from enjoying the benefits of stove fans. Traditional fans were designed to sit on large, flat stove tops, making them unsuitable for inset or insert stoves. This left a significant portion of the market underserved, and a solution was urgently needed.
In 2016, that solution arrived with the release of the Sirocco Plus stove fan. As the name suggests, it builds on the original Sirocco with the addition of a Vertical Mounting Kit (VMK).
The Sirocco, manufactured in Lithuania by the German company Hansa, was one of the first stove fans on the European market. Weighing nearly 2kg, it is heavier than most Peltier-powered fans. It features a large heat sink that stores energy, allowing the fan to keep running long after the fire has burned down. The fan’s base includes three adjustable screws that act as feet, as well as six threaded holes, so it can be levelled on uneven stove tops. These countersunk screws also lift the fan slightly to protect the motor and Peltier module from excessive heat.
The Vertical Mounting Kit developed by Hansa’s engineers can be fixed to virtually any stove door front and attached to the fan using the pre-existing screw holes in the base. This allows owners of built-in stoves to finally benefit from the heat circulation that a stove fan provides. In essence, the Sirocco Plus is the original Sirocco fan combined with the VMK.
As of November 2017, the Sirocco Plus remains the only stove fan that can be adapted for built-in stoves.
Many stoves, such as soapstone stoves or gas-powered stoves, rarely reach surface temperatures above 250°C. These stoves require specially designed fans with an optimal operating range around 150°C. Surprisingly, there are now several Peltier-powered fans designed for this purpose, as well as even one Stirling-engine model.
The Glasshopper by Warpfive is a miniature Stirling engine fan built to operate on lower temperatures. Its engine design has been modified from Warpfive’s high-temperature models—for example, with a larger cylinder and lighter components—so that it can start running at just 70°C and operate effectively up to 300°C. Like all Stirling engine fans, the Glasshopper is not only functional but also fascinating to watch in action. However, as with all Stirling fans, it comes at a premium price—typically well over £200.
Another dedicated low-temperature option is the Ecofan BelAir, introduced by pioneering stove fan manufacturer Caframo, based in Ontario, Canada (about 150 miles from Toronto). Standing under 160mm tall, the BelAir uses two Peltier modules to generate enough power to deliver an airflow of up to 140 CFM, making it a compact yet capable solution for soapstone, gas, or other lower-temperature stoves.
If you are still unsure about the effectiveness of stove fans, and feel that the price can be quite an investment, we are pleased to introduce a great little starter fan. It has a retro design reminiscent of the first fans brought to market by big brands such as Caframo and Valiant nearly a decade ago.
Since then, the market has been inundated with hundreds of cheap models, mainly from China, with brands like Voda and VonHaus leading the way. They offer bargain-priced products that will work to some extent, but quality and durability can be hit and miss. Customer support is virtually non-existent—if the fan breaks, you simply buy another one.
All stove fans should be kept away from the flue pipe—Peltier-powered fans in particular are very vulnerable to overheating. These should be placed at least 100mm away from the flue. If the fan is positioned in front of the flue, leave a 150mm gap.
Because of their unusual construction, SmartFans should be placed so that their axial fan never draws in air that has already been heated by the flue pipe, which typically gets hotter than the stove top itself.
The market is flooded with extremely cheap stove fans and, as with any product, there are plenty of flimsy copies of quality designs. We cannot recommend them, as we only test the fans listed above and always back them up with top-notch customer service—just check our verified customer reviews.
Stove fans are very easy to use and have been proven to improve both heating and fuel efficiency. The key is finding one that matches your stove, room size, and aesthetic preferences. And if you’re still not sure which one to go for—drop us a line, we’re here to help!
