Wood and pellet stoves are an efficient and green way of keeping your home heated. However, a major disadvantage of stoves is that they can only heat the neighbouring air, meaning unless you are situated close to the flame you won’t get very warm.
This issue can easily be remedied with the use of a good quality wood stove fan which modulates the way in which the hot air is circulated and distributed equally into your living space, resulting in a more comfortable and warmer environment. However with so much choice out there, it’s wise to know which fans are the best and which should be avoided. That’s why we’ve analysed some of the best fans out there and made our recommendations based on the results.

What is a Stove Fan?
A blower or fan is composed of rotary blades that are designed to circulate the warm air heated surrounding and heated by your stove. This is advantageous since heat rises it tends to get trapped in the upper portion of your living space meaning the heat generated is not doing what you want it to do – keeping you and your family warm.
The rotation of the blades offers a simple yet effective solution, by recirculating and re-positing the hot air through your living space your heat will quite literally go further than ever before. The best part about many fan models is that the majority don’t require their separate source of power since they are usually powered using the heat of the stove.
How Does a Stove Fan Work?
The majority of fans today are powered by a Thermoelectric Power Generator (TEG) or a Sterling Engine.
- TEG Power
Stoves that utilise TEG are most common out of the two. This device operates using a thermoelectric module, which consists of negative and positive semiconductors. Heat is transferred from the hot area i.e. the stove, to the cold metal of the fan, resulting in an electric current. As a result, the heat produced from the stove is converted into electrical energy via a phenomenon known as the Seebeck effect. The energy produced then causes a rotary motor to start working and leading to the desired fan motion.
A major advantage of TEG models is that they are extremely reliable, do not require any other source of energy and since they do not require any movement parts they are possibly the safest option out of the two.
- Sterling Engine
A sterling engine or heat engine also utilises the heat energy produced by the stove. The engine utilises a cycle of compression and expansion caused by compressed air at different temperatures. The heat from the stove causes hot air to expand causing a piston to contract, while the piston in the portion of the engine containing the cold air causes another piston to retract. In turn, this leads to an overall conversion of heat energy to do the mechanical work of turning the fan blade.

Where Should You Place Your Fan?
In order to maximize the performance of your fan ensure you position it on a smooth, flat surface on top of your stove. Ensure that you place it in the middle or back of the stove and as far away from the flue pipe as possible. In addition, avoid placing it at the very front, or centre. The ideal placement is at the edge and middle position, this is where the cooler air can be drawn from behind and over the cooling fins for maximum benefit.
Why is a Stove Fan so Important?
The majority of wood stoves come accompanied with a blower also called a fan, however often these aren’t very good and compared to the best wood stove blowers out there would perform pretty badly. The truth is that a woodstove fan can save you money and heat your home a lot better since they can circulate the warm air equally throughout your living space and prevent it being lost up your chimney.
A wood stove fan is often overlooked by many people as just an unrequired extra gadget, however, the reality is that a good quality stove fan can make a massive difference to the heating of your home. Without one, the heat produced by your stove is likely to stay in one area and be lost up your chimney, therefore losing you heat and money. That’s why investing in a stove fan is a wise idea, it can dispense the hot air throughout your home instead of it being lost and wasted.
How do you know whether you’re looking at a good quality blower? The answer is that there are certain features you should look out for before parting with your money.
What Should Look For in a Good Fan?
- Automatic Control: this means your stove will automatically detect a certain temperature and will be triggered to start running. This means you no longer have to manually switch it on and off, which believe it or not is incredibly easy to forget. Certain fans are actually run on a heat powered fan, which means they are powered by the heat produced from the stove, this is known as the Peltier Effect, and this saves you on batteries too.
- Noise Control: most fans create some level of noise and to most people this is acceptable. However, if you live in a small home or it is particular noisy this can become a nuisance, to solve this issue you should opt for a heat powered wood stove fan, as they tend to be a lot quieter than electrical powered blowers that utilize a noisy motor.
- Simple Installation: when installing anything new and functional, you want the process to be as simple as possible. Ideally, you want to choose one which easily fits into the piping on the outside of your wood stove. This will distribute the heat nicely throughout your room, although if you prefer the heat to be distributed through your entire home, then you should opt for one in a vented system instead.
The fan reviews above should provide you with a starting point in searching for a fan to suit your requirements. In our view, a wood stove fan is a necessity if you heat your home using any form of stove – pellet stove or wood, as without one you’re literally throwing away hot air that costs you money and if circulated adequately could keep you warm for longer.
There are many wood stoves out there, but the best ones are those that make a little noise, are heat powered and circulate air efficiently, so always check the specifications before making your decision, as your fan is likely to be with you for many years.
