I watch a lot of reviews for different items, I appreciated yours probably the most. Well thought out and not 10 minutes on each fan removing it from of the wonderful cardboard box. You focused on what I think most of us would want to learn in a review
Dude, this was so helpful!!! I'm so thankful I found it. We just purchased two wood burning stoves and now we need to choose a fan for each. Thank you!
Thank you for this video. It was well done and informative. This is EXACTLY why I watch reviews on RUclips. Practical first hand experience in a well thought out demonstration. Thank you again.
I'm not sure i totally agree with these results only because each fan produces a set amount of cfm at a given temperature. Each fan should have been tested at THIER MAX heat range in order to achieve proper CFM for testing. I am currently looking for a stove fan, was looking at the GALAFIRE V366 or the V266. However, you are the ONLY RUclipsR that I know to have used an actual anemometer... very cool! Now I am not sure 76 USD is worth any of these
THANK YOU! I've been looking for a review just like this. There's so many to choose from on amazon with reviews that are all over the place. Wasn't able to find that fan on amazon but found it on ebay. Will be ordering it.
The one at 2:40 that turns but produces no wind is not a defective blade design but has the wrong polarity for the motor. It blows backwards. They soldered it the wrong way. Easy to fix actually. But oh well... at least to turn the fan the other way might help a little ... although the design is not symmetric for the blades so it wont be ideal. The best is to resolder it and invert the wires going into the motor. By the way quite a few people complain that those fans are rubbish and dont work. My guess is that these people have unfortunately bought wrongly soldered items...
you should have measured the temperatur of the heat plate because it depends a lot on the fact how hot your oven is. mine was much too cold to run a fan propperly. Tests it at different surface temperaturs and so you can see the increase in cfm or at what temperature it makes sense to use such a fan
Your efforts appreciated, but you missed some important factors: 1. They have different sizes, so absolute air movement is not really honest to compare this way and 2. The noise they make is at least as interesting to compare in a complete review
He did compensate for the different sizes right at the start, the anemometer was programmed with the size of the fan to give a CFM reading rather that just a velocity, He mentioned the noise as well.
Yours was the best comparison on stove fans so far. I own the TIEMORE stove fan, 2 fans 4 blades ea i paid 74.00 on feb 2021, its now 88.00 on amazon. the blades dont have a guard around them, so they can be bent easily, if not carefull. its rated at 32db extremely quiet. the bimetal strip under the base will automatically bend to help raise the fan base and reduce the contact area of the heat source to protect the motor and the thermoelectric module.

figures, only one that actually works decent, sold out. Hope you do others, there are some that claim 340 CFM, passive. Would love to see that reviewed.
Very well made video, but one factor I would like added, is the temperature at which the fan starts to turn. I have the twin bladed Aldi model which starts up very quickly. My only question that has never been mentioned is, can you lubricate the shaft? If so, with what product? ie, grease, oil, silicone, etc.
Methodology for the test is terrible. You are only taking the airflow from part of the fan not the whole fans output. Given different sizes this favours the smaller fans as the larger fans are not having a substantial part of their output checked. The dual bladed one for instance was having less than half its output checked....though the noise would have it thrown out pdq anyway
love the review. As everybody else has said first honest short sweet and to the point review. Thanks. My only questions are, for ignorant peasants, like me! what is CFM,(perhaps put the answer to this in the video explanation above) and is there a motor size difference or do they all run on the same size? I am looking at putting a fan on to my oil burning cooker flue (AGA) to see if I can get some heat out and into the room. If you have any reviews on them, that would be great too. Thanks anyway
Having watched loads of these fan videos, none shows a before and after comparison. Test the room temperature with just the stove burning and then test with the fan on top of the stove. If the fan does not move enough warm air into the room, it just winds up as an amusing gimmick.
I've had my Voda 360 cfm twin-fan for a few weeks and I gotta tell you this one does as stated on the box. The one he tested that showed zero cfm was weird and I have no explanation for that reading (but I'll bet the advertising for it said it was a great device LOL). The type of testing you suggest sounds like a lot of time, expense and effort on the part of someone just to show you the things aren't novelty devices. If a manufacturer did a test like that I wouldn't trust the results bc I'm certain their fan would be shown to be the best.
It seems a lot of air the fans push isn't going through the anemometer and so it's not gauging cfm correctly although it DOES indicate which fan moves the most air.
obviously a bit of intereference that needed to be rectified on the dual shaft setup at the end. Shouldn't have been a major repair. Also the "zero" fan just needs the blades tweaked to actually push air, obviously they're too "flat" and aren't getting any "bite" on the air. If indeed it's blowing the right way as noted by the commenter Ghioca.
Your video shows you used both a 3 bladed and 4 bladed Signstek but you showed the results for the older 3 bladed model. What was your purpose in the switch?
I believe your numbers are wrong, because your anemometer isn't calibrated correctly. It is useful only for comparison purposes. I believe you have set the airflow area in the anemometer settings incorrectly, as the CFM is calculated based on air velocity across a specified area. Sources: 1)The PM6252B user manual 2) An Arctic 140mm PC fan running full power moves 72.8 CFM and can be felt as a gentle breeze from 4 meters away. It moves hair like a strong wind when close.
I saw that too. WTH is that all about? He shows us a box with a 4 bladed fan but the fan itself has 3. Then he places a fan on the hot plate with 4 blades but clearly when he tests the airflow, he's switched back to the 3 bladed one because you can see the heat sink shape is the one from the 3 bladed one we saw out of the box in the beginning. Just because of that alone, I have no faith in this test. Guess I'll have to keep looking for an impartial forthright product tester.
Thanks, mate! Your test narrows the search significantly. I have electric and gas heaters. Does anyone know if I mount the Peltier fan's base in front of the heating elements (on a heat sync?), would it work?
Doing what you are thinking of might not get the peltier hot enough but its worth a try , some are very cheap on Ebay so i would maybe get the cheapest and give it a go . Good luck
You might get the blades turning or you might just burn it up. The electricity that makes the fans turn is created by heat moving upward through the thermal coupler located between the base and the upper "radiator" part. When mine is turning fast the base is too hot to touch while the upper part is considerably cooler (but still very warm to the touch bc that's where the air being blown forward picks up heat). I ruined the first one I had in four hours by overheating it on top of a Mr Heater running on the Hi setting, which is just about as hot as an open flame and so is hotter than the top of a wood fuel stove (but the room got warm quickly LOL)
It depends what temp it was tested it. If it was tested at the average temp of a stove it wouldn't of made a difference. If it was colder then the fans would be slower.
Molto interessante. Non conosco l'inglese ma ho cercato di capirne qualcosa dalle immagini. Domanda, sopra una stufa a gpl ad infrarossi quale consiglieresti. Grazie e buon giorno.
Ciao, volevo chiederti se alla fine lo hai preso per la stufa a GPL... Ed eventualmente chiederti un feed su questo articolo. Funziona realmente o e meglio lasciar perdere?
You're measuring velocity, air speed, not CFM! In order to measure CFM, you need to multiply velocity by area, which you don't have an area because of the open area around the fan and meter.
the YH-BLS802 is spinning in the other direction. It is pulling air instead of pushing. That is why you have not reading...or maybe my eyes play some tricks on me.
All the fans tested were under £40 and we took a range of shapes and sizes. It wouldn’t have been possible to test every fan on the market, but we did our best.
@@MrPiedy00 I watched the video very closely several times . The meter DOES indeed show a reading of 77.4 in front of ONE blade . YOUR logic makes no sense .
The meter was calibrated for each fan individually before the test. The total area of all the fan blades was measured then the meter can multiply this figure by the flow of air through it to give an overall CFM reading.
When you tested the 2 blade fan you only had the meter in front of ONE of the blades , so shouldn't the 77.4 be doubled to 154.8 putting it in first place ??
Would that fan work if a person set of a heat source from a set of "tea lights"? Could you to a test run to see how many tea lights it would take to generate adequate heat? This might be a good item for those in Europe to use this upcoming winter when their heating fuel will be diminished!
@@MrPiedy00 SO, without a measurement of the hotplate, this test is ambiguous at best.... IF you can afford an anemometer, you can sure as hell afford an IR temp gun...... UNLESS the hotplate was somewhere in the 300- 400 degree F range, you are, as they say, "watering in the wind"....
Why isn't is the Vulcan Stirling motor stove top fan in this 'comprehensive' review?? The one fan you didn't review, which is far more powerful than all of the reviewed fans!! Bit disappointed.
We haven't claimed this to be a "comprehensive review", all the fans we have reviewed were priced between £25 and £40, the Vulcan Stirling motor stove top fan is priced at over £120 so it wouldn't have been a fair, like for like comparison.
Oh no youre disappointed?? Why dont you write it in your diary?? and if it still hurts maybe you can cry me a river... Shut up and do your own damn fucking tests..
The sensor doesn’t work that way. The size of the fan blade was measured and that’s divided by the sensor area to get and accurate result, and a fair comparison.
I watch a lot of reviews for different items, I appreciated yours probably the most. Well thought out and not 10 minutes on each fan removing it from of the wonderful cardboard box. You focused on what I think most of us would want to learn in a review
Thank you god for this person that takes a scientific approach to comparing fans 😅
This was really well done. I wish a lot of other reviews were so clear and to the point.

Why weren't these put on the same position on the range each time? Some of these had a bit hanging off the range.
You did not place the fans in the same place on the hot plate, also the meter wast not moved around for the optimal air from the fan.
Thank you for your help in choosing the best model. The world is becoming a better place thanks to people like you and those people at Cosystove.
Do you have a link for cosystove
EXCELLENT review! Thank you. You cut through the chase and gave an ACCURATE, CONCISE & TIMELY review. Liked, subscribed, & hit the bell.
Great review...thanks for checking that dual fan setup...much luck to you 👍😎
Can you also review Stirling engine stove fans?
Thanks!! It answered all my questions and gave me a direction.
was there a difference in regards to sound between the top 3 competitors?

There is any motor inside

Do a review to see if you can change the blade pitch to improve any of the reviewed fans.

the blades dont have a guard around them, so they can be bent easily, if not carefull.

the bimetal strip under the base will automatically bend to help raise the fan base and reduce the contact area of the heat source to protect the motor and the thermoelectric module.

CFM = Cubic Feet per Minute..........
Aldi have the one rated 2nd atm for £15
obviously the double fan was not supposed to make that noise and its rubbing was reducing the blade speed
Yes, probably a very easy metal tweak would have resolved it--unless the shaft was bent. But this guy just gives up and moves on...
4:27 sounds like a blade got damaged and is hitting the main assembly, or by poor design the blades from the two fans are colliding with each other.
Having watched loads of these fan videos, none shows a before and after comparison. Test the room temperature with just the stove burning and then test with the fan on top of the stove. If the fan does not move enough warm air into the room, it just winds up as an amusing gimmick.

I wonder if you would have got different values had you used a proper log burning stove ?
It depends what temp it was tested it. If it was tested at the average temp of a stove it wouldn't of made a difference. If it was colder then the fans would be slower.
Are they all noisy?

I thought this as well, but wouldn't the meter move if it was drawing air? Or maybe not at that distance. This is no Project Farm, that's for sure.

u would end up in jail or knocked off by the oil companies haha
Thank you 😊
Valiant Premium FIR361 ?.......only test a tiny percentage of the market.
Hardly a comprehensive test. Not tested are fans from Ecofan or any other brand available on Amazon.
All the fans tested were under £40 and we took a range of shapes and sizes. It wouldn’t have been possible to test every fan on the market, but we did our best.
It would be great if this was remade with proper measurement units.
Heat Powered Dual Fan shows 2 fans and testing 1 fan at 77.4. Times 2 fans would be 154.8 cubic feet.
I understand your logic but the surface area of both fan has been taken into account so the original CFM of 77.4 is correct.
