One other benefit of stove fans is that they can also help with distributing heat in small rooms where it may get too hot. They can work to create a more even temperature throughout the whole space. In terms of noise, this stove fan runs at <35dB which is very quiet, equivalent to the sound of whispering. If you’re in a silent room you will likely hear it whirring, but it shouldn’t detract from watching TV or listening to music. The VonHaus 4-Blade Stove Fan starts with its somehow rustic yet, at the same time, sleek profile, with smooth and polished fans but rough, sanded-looking base. We are not talking about anything that different from most stove fans but there's something about its finish, something understated, subtle, and attractive. What's also attractive about this unit is the increased size, measuring 22.5 (height) x 19 (length) x 9 (width) centimetres to make maximum impact. When the bi-metallic strip senses that the stove is too hot, it expands and lifts the base of the fan away from the top of the stove. As a result, the body of the stove fan is somewhat protected from the heat of the stove. This usually happens at temperatures over 300 °C , and it’s a good idea to use a stove thermometer to keep an eye on the temperature of the stove – too hot a fire can damage the stove itself, as well as a fan on top. Another plus is the low starting temperature of 50˚C (lower than many of the other models here), meaning you can make the most of the heat given out by your stove as it comes up to its maximum temperature. How to choose the best stove fan for you:

This stove fan has a starting temperature of 50 – 60°C; it will start to work without any need for electricity or batteries. It spins faster as the temperature of the fire increases, effectively pushing heat out into the room. Operation is praised for being quiet, while the design is subtle and easily blends in with the majority of stove styles, both contemporary and classic. When in use, there is a noticeable difference felt in the room temperature, stopping heat from getting trapped by the stove.The size allows this stove fan to properly distribute heat around a room, reducing the amount of heat that is lost up through the chimney or up to the ceiling. The four fan blades are good quality and begin rotating when the temperature of the stove reaches 80°C. If you’re looking to increase the efficiency of your wood stove, without spending loads of money in the process, the VonHaus 4 Blade Stove Fan is an effective, budget option.

When placing the stove fan on top of your wood stove, i t needs to be as far away from the flue pipe as possible and on a level surface. Already, this may limit the amount of space you have available for a stove fan, even before taking headroom into account. Stove fans don’t start running as soon as the wood stove is lit, they usually jump into life when the stove heats up and a certain temperature is reached. Second, if you have a very large room, consider buying a bigger fan to ensure it’s capable of circulating enough air around your room. Some – but not all – fans list airflow in cubic feet per minute (CFM), so in this case look for fans with a higher CFM figure. Where do I place the stove fan? Most stove models aren't able to produce more airflow than ~250 CFM. The fan that we're reviewing here has no issues reaching 430 CFM. Of course, the difference stems from the model's double-head build. Equipped with 8 blades, the fan circulates 50% more warm air compared to traditional 4-blade fans, making the model the most effective and, at the same time, efficient way to heat any room from the stove.It’s been designed to work between 85 – 350°C; however, you need to be careful that your stove does not exceed this maximum temperature as otherwise the fan and its components can get damaged. Look for a heat powered stove fan with 3 or 4 blades . These are best suited to small and medium domestic rooms. Alternatively, a dual fan, or multiple small fans, may be the best option for larger spaces – these provide the power of a larger model but within a compact size. A fan with a base of around 15 cm will fit on most stoves, distributing warmth without getting too close to the flue pipe.
