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

The media could not be loaded.  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.

Exactly as stated the fan starts at 50 degrees celsiusIt 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 1Would highly recommend

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.

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.

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.

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.

does what it says, quiet and efficient
