Information About the Ventum II Fan, By Valiant

Valiant is a small company based in the UK, well known for their excellence in engineering and production of high quality, durable products.  When the company first introduced its line of stove fans, they did so with the Valiant 2-blade model.  Since that time, the design has been tweaked and improved, resulting in the Valiant Premium, a four blade model, which led to the development of the Ventum sub-line of stove fans, of which, the Ventum II is a part.  Needless to say, this new fan on offer by Valiant has an excellent pedigree, and decades of high quality engineering expertise poured into it.

Like all of the fans in the Valiant lineup, this fan requires absolutely no external source of power to run it.  It derives all the energy needed to move the blades and push the air from the heat of the stove you put it on, using a well-known scientific principle called the Peltier Effect.  This is tested, tried-and-true technology you can count on, and not some glitch newfangled innovation that’s prone to breaking after the first few uses.  Couple that with Valiant’s world-class customer service and outstanding, industry leading two-year guarantee on materials and workmanship, and you can buy this fan with total confidence that it will serve you well.



The packaging of the Valiant Ventum 2



The inner box of the Valiant Ventum 2

The Valiant Ventum 2 comes neatly and safely packaged in a sturdy box, so you can rest assured that it will be delivered to you in mint condition.  However, it can be a little tricky to get the fan out without actually damaging the box.  We have discovered that if you open the sides first by gently pushing the them out and remove the fan base first this keeps the box intact ready to use again should you need to return your fan whilst it is still in warranty.



The bi-metal strip protects the Valiant Ventum 2 from overheating

As with the other Valiant fans the Ventum 2 comes with a built in bi-metal strip on the fan’s base, which protects it from overheating.  How does this actually work?  When the temperature of the stove top reaches 300 centigrade, the strip bends and gently tips the fan backwards.  Not only does this protect the motor from overheating, but it also protects the TEG (Thermoelectric Generator) Module from overheating.  The TEG module is particularly exposed to high temperature, but can get damaged easily.  We recommend using a thermometer as well, especially if you expect your stove to heat in excess of 300 centigrade.  If your stove does reach the upper limits of the temperature range we suggest you use the small handle on the top of the fan to remove it from the stove top.

The question that naturally arises then, is who should consider this fan?  The general principle is that the bigger the space you’re trying to heat with your wood burning stove, the more blades you want your fan to have, because more blades translates into more air moving power, and the goal, of course, is to get all that warm air from the immediate vicinity of your stove, and into the rest of your room.

Valiant Ventum 2 specifications tableGiven that the Ventum II only has two blades, that tells you right up front that you’re probably going to want a fan with more blades if you’re trying to circulate air through a very large room.  Don’t let the Ventum II’s twin blades fool you though, it pushes more air than you might think for a fan with just two blades.  An impressive 420 feet per minute!  All that to say that while the Ventum II is ideally suited for people with smaller rooms, it can do surprisingly well even in medium sized spaces.

In terms of size, there’s a lot to like here.  Often, when people think of fans, their mind immediately gravitates to big, clunky, boxy fans that make a terrible racket when run.  The Ventum II’s small size will be surprising to some.  It measures just 174mm high (including the height of the blades!), a scant 155mm wide, and has a total depth of just 110mm.  It weighs just 475g, so this fan can be installed even in very tight, constricted quarters and work just fine.



The Valiant Ventum 2 is powered with a TEG module

The Peltier module is held in place between the upper and the bottom section by two easily accessible Allen screws. If you ever need to replace the Peltier, it should take you no more than 5 minutes to do so.



The Valiant Ventum 2 wiring

The Peltier module and the motor are connected by a tiny plastic plug, which can be used if you ever need to replace any of the two. Despite the fact that the plug and the wires are exposed, they are perfectly safe and protected, as long as they stay within the recommended temperature range.



The Valiant Ventum 2 motor mounting

The motor for the Ventum 2 is easy to get to, but it is highly unlikely that you would ever need to access it.  A far more likely problem is bending the blades, should you drop the fan for example.  If the blades become bent they can cause an irritating noise.  Replacing the blades shouldn’t be a problem, as they are released by an Allen key.


The Valiant Ventum 2 motor mounting

The Ventum 2 is only 18cm high, which makes it one of the smallest Valiant models currently on the market.  This means it fits perfectly in even the smallest of spaces above the stove top.

Perhaps the best part though, and another way that Valiant’s exquisite engineering prowess comes shining through is the fact that the fan has an extremely low start up temperature of just 45 degrees Celsius (113 Degrees Fahrenheit)  so it will start running not long after you light the fire in your stove, and begin pushing warm air throughout your room.  When the fire eventually dies out, the fan shuts off automatically, with no input from you, making it a truly “set and forget” solution for increasing the overall efficiency and effectiveness of your wood burning stove.

The bottom line is that if you use a wood burning stove for home heating, you should seriously consider getting a stove fan to augment your system, and Valiant makes some of the best stove fans in the industry.  If you are trying to heat a small to medium-sized room, then the Ventum II is an excellent choice.  If you’re trying to heat a larger space, consider the Ventum III or the Valiant 4-blade (insert links as appropriate here).

    Small and unobtrusive, very quiet and high build quality. Perfect for the smaller room.

  2. Rated 5 out of 5

    Fits into a small space and is quiet and very efficient.
    Very pleased with product.

  3. Rated 5 out of 5

    Fits perfectly into small space on top of stove within the fireplace recess. Very quiet. Starts up quickly after lighting stove and shuts down automatically when stove cools down. Definitely creates a more even distribution of warmth through the room and has also helped to circulate the warm air through into adjoining room and hallway. Perfect for what we wanted.

  4. Rated 4 out of 5

    Neat little fan, very unobtrusive and starts up on very little heat. Perhaps I should have bought a larger one as it doesn’t pack the punch I had hoped for.

  5. Rated 5 out of 5

    Brilliant, almost silent, little fan, ideal for our 5kw Broseley wood burner. Really helps to move warm air around the room. Fantastic service – delivered the day after ordering and at one of the best prices online for this fan.

    This is a nice little fan. The only one I could find for the small space I have. It's silent and really does the job of pushing the air around the room better. Perfect. The information on the website also helped in positioning it correctly.

    Just the right size for my Conrura stove. Runs quietly and the cold spots that we had in our lounge have now disappeared. Very pleased with this product. Delivery was prompt and the price was the best we could find.

    Great, fan at a good price compared to other sites. This was the only fan that will fit between the top of our wood burner and the chimney plate. Fan came the next day and makes a huge difference to pushing the heat from our wood burner into the room, would definately recommend.

    Before buying the Valiant Ventium II I did consider a cheaper fan but I'm so glad I went with the Valiant. It starts up and a VERY low temperature and has a large operating heat range. It also has the bi-metalic strip underneath that tilts the footplate of the fan back on it's heels if it starts to get too hot which prevents it from over heating and damaging the motor and TEG module.

    The fan is very quiet, you can just hear its fluttering noise if there is absolutly no noise at all in the room and what you can hear is so gentle that you will not be annoyed by it at all.

    I have had the fan for about 4 weeks an have used it every night, so far I could not be more pleased with it.

    Had searched for a long time for a fan that fitted in the limited space above the stove and discovered the Valant Ventum ii. It has made a great difference in pushing warm air around the room so that's good. The service from Stove Fan Review was excellent, fast and free delivery.

    We have a small woodburner in an enclosed fireplace with a limited opening and all the heat seemed to be sitting in the chimney breast between the register plate and the top of the woodburner. Bought this fan based on it's suitability for the limited operating space we have and are amazed with the difference. The ambient temperature in the lounge increases far more rapidly and to a much higher overall temperature than before – this can easily be seen by the central heating thermostat in the room! Was sceptical how much difference this small device would make but am delighted with it's performance and highly recommend it. Even considering buying a second one to place on the other side of flue to increase heat into the room even further. Best price I could find online too!
