Do I Need A Wood Stove Fan?

Wood stoves are great. They’ve got a delightful, rustic feel about them and are a popular way of heating many homes across the country. The one problem they have though, is that while the area immediately around the wood stove gets nice and toasty (and perhaps even a bit too hot!), the rest of the house doesn’t get a lot of benefit. That’s where the Smartfan comes in!

Wood stoves provides comfort

Developed over a period of two years, the goals behind the Smartfan were simple. Its creators wanted to make a fan that would radically improve the efficiency and overall effectiveness of the classic wood stove that so many of us love and use for home heating.

Three Requirements 

In order to achieve that goal, the fan had to do three things, and do them really well. It had to be easy to set up and install, it had to be automated, and it had to use very little electricity. This last element was especially important because of course, one of the major reasons that people invest in wood stoves for heating is so they can reduce their electric bills. It wouldn’t make much sense then, to run a fan that used electricity, just so you could improve the efficiency of the stove – that would see the fan essentially working against itself!

Fortunately for you and for the company that make it, the Smartfan delivers on all three. We’ll explain exactly how, just below.

Is It Easy To Install?

First, the Smartfan is easy to install. It can be accomplished in just a few minutes’ time, and with only very basic tools. The unit comes assembled, so it’s really just a matter of mounting it where you want it to go. As mentioned, that’s a big win for consumers, who don’t want to get bogged down in something that’s needlessly complex.

Does the SmartFan Need Any Maintenance?

The second and third points are so interrelated that it’s probably best to discuss them together. The Smartfan is about as automated as it can possibly get, because the heat from the stove is the mechanism that controls when it powers on, and at what speed. Sensors in the fan detect temperature. At a certain temperature, the fan will begin operation on its own. In general terms, the hotter the stove, the faster the fan blades turn. It’s not quite that simple, but we’ll get to that in a moment, just below. The important thing to note here, however, is that there’s nothing to manually turn on or off. The fan’s operation is controlled by the heat produced by the stove.

How Is It Powered?

This is also what provides power to the fan. The same heat that warms your home is also converted into electricity to power the fan. That means you’re not drawing power from the grid or a battery pack. This is the key feature that makes the fan so efficient, and really what improves the overall efficiency of your wood stove. It improves efficiency by circulating all that gloriously warm air into the rest of the room. The problem of it being too hot right next to the stove, and too cold in the rest of the house is solved neatly and efficiently by virtue of the presence of the fan.

The Wood Stove Fan Operation

The stove gets hot, reaching the temperature threshold that powers the fan on. The fan blades begin to turn, pushing the warm air out through the room, providing you with a more even heating solution. The best part though, is that the Smartfan goes beyond even this. There are actually two fans working in tandem. The primary fan is the one that moves the warm air outward into the room, as described above. The secondary fan, however, is responsible for cooling the top section.


By keeping the top section cool, it creates a wider temperature differential, and this is the mechanism that provides maximum thermos-electric output. It also goes quite some distance toward keeping the unit from overheating, which could cause it to burn out. The secondary fan thus performs two functions at the same time. It increases the overall efficiency of the unit, and it prolongs its useful life. As far as engineering goes, you just can’t get a better solution than that!


The Smartfan also comes in four different versions, each designed to suit specific customer needs. There’s the Smartfan, the Smartfan Mini, the Smartfan LT, and the Smartfan LT Mini. The “LT” models are designed for operation at much lower temperature thresholds than the original Smartfan, making them ideally suited to lower temperature environments.

This comes with the tradeoff that the LT fans are simply not capable of operating in high temperature environments. They will burn out, despite the presence of the auxiliary fan. Thus, it is important to understand which of the two varieties is best for you, by understanding just how hot your stove tends to get.

Whichever one you choose, however, the Smartfan is a marvel of engineering excellence that will serve you well, making your wood stove vastly more efficient and effective at heating your home.
