[ 2 Years ] 50°C Start Silent Heat Powered Wood Stove Fan 4 Blade Black Small for Gas/Pellet/Wood/Log Burning Stoves + Thermometer

I've been searching for already 2 seasons for a good fan to enhance the yield I get from my woodstove. My particular situation is that my stove is positioned in an old fireplace chamber, so not only that any wood-burning stove is not so efficient in heating the room (comparing to Fireplace Insert due to the integrated fan) but also a significant part of my stove heat remains in the chamber and thus escaping the chimney. There are 2 most important thermal transfer methods, namely convection (diffusion of hot air flow above stove) and radiation (electromagnetic energy), while convection is by far the most dominant in heating the room, and since a stove is not highly efficient from convection perspective especially when heat is stuck inside the chamber as in my case, I had to find a way to extract the hot air above it into the room. I've tried a 2-blade from "My Stove Fan", a 4-blade from "L-Best stove accessary" and a 4-blade from Gif4yourhome / VIOLA-tech. I've even tested the fans side by side, and also individually and measured the temperature increase in the room thanks to each one of the fans, and tried to be objective with respect to similar outside temperatures and weather conditions, and turning the heating system off during the testing, and operating in similar constant stove temperature. I have to say that when I received the Viola fan it looked much smaller (and much lighter) than the other fans, which can assert some scepticism regarding its capabilities. Though it is small it seems to give more air flow CFM than the others, and also a 4 blade blows more than a 2 blade (in theory and in practice as well!). The Viola fan certainly lives up to its promises in my case. Fan starts at the lowest chimney temperatures from the 3 fans (at ~50°c and also according to specifications on product page) and I consistently get a higher temperature increase in the room using the Viola fan comparing to the other two. The Viola fan manages to raise the temperature in my 270m³ livingroom by about 0.6 degrees in first hour, higher by roughly 20% when compared to the other 4 blade fan (and funny enough they seem to be priced accordingly too:-). I enclosed a picture and a video in action. Note that I screwed out my metal strip protection in the bottom of my fan as I think it is not needed in my case since I never reach critical temperatures since my stove operates between 150 to 200°c.

We have had a stove fan before, but this one works so quickly - hardly lit the fire and it starts to spin. Really efficient - anyone who has a log burner needs one of these.

Exactly as stated the fan starts at 50 degrees celsius It is almost perfectly silent. I can only really hear it if there is no other noise in the room and I am actually trying to hear it. It moves the hot air about the room with ease. I have had the product 2months with it being in use every day, and can say it works the same today as it did day 1 Would highly recommend

I had a new woodburner installed with limited headroom for a fan - this fan was perfect for my needs and a bonus to have the thermometer too

I bought this fan to sit on top of my multi fuel stove. I am really pleased with it. The room heats up a lot quicker initially and the overall temperature is a lot higher. The fan is well built and heavy.

Very pleased with these fans, the difference it has made within the rooms by using one on each burner, considering adding another to each one as so effective.

so efficient throws a lot of heat into room

Not silent. In fact its louder than the TV. Pushes the heat around a little. But isn't making much difference. Could be because we have a large living room. Was hoping it would be better tbh.

Un producto excelente que hace lo que dice. Se dispersa el calor de la estufa en toda la habitación sin costo adicional de electricidad y da 40% de ahorro de energía. El contacto personal con Vivian, Smartsstovefan, PR de la empresa fue excelente. ¡Muy recomendable! NR

Gleich vorne weg - ich bin begeistert. Der beheizte Raum hat eine Grundfläche von ca 50qm, 2 geschossig (= Empore) und hat als einzige Heizung einen ziemlich mittig angeordneten Holz-Schwedenofen. Dieser wird zwar ziemlich heiß, verteilt die Hitze aber nur bedingt, zudem diese natürlich auch direkt nach oben steigt. Richtig platziert (nicht vor dem Abzugsrohr sondern daneben) läuft der Ventilator nicht nur sehr schnell an (das mitgelieferte Thermometer zeigte am Abzug 100°C, ein anderes Thermometer zeigte erst 60°C), ich musste ihn auch nicht "anstubsen" und er verteilt die Wärme derart gleichmäßig dass die Kleiderordnung in demselben Raum von Norwegerpulli zu T-Shirt wechselte. Dabei ist direkt vor dem Gerät bis ca 80 cm davor ein Luftzug zu spüren der jeglichen Versuch eine Feuerzeugflamme davor zu halten zunichte machte. Der Ventilator macht ab einer gewissen Geschwindigkeit ein nicht sehr lautes surrendes Geräusch das mich persönlich aber nicht stört.

Super quiet, starts at low temp, you actually feel the air moving with this fan. Couldn’t be happier after a less than stellar experience with another company on here and a fan from a store.

Ont eu 3 mois maintenant et il augmente la production de chaleur de quelques degrés

It does exactly what it is supposed to do, circulates air around the room once the combustion heater reaches a certain temperature. It is very quiet and you wouldn't know that it was running. Very effective in heating the room quickly. Packaging from the states was good with an instruction book that wasn't really needed as it was ready to go as soon as you put it on the heater. A small temperature gauge came with it and that tells you the best perimeters for effectiveness of the fan. No power cords, no batteries, it works!
