I've had mine for 5 years. Works great on my wood stove. I just put a shelf on my buddy heater and now I use the fan on the buddy heater and it works great as well.
The fans aren’t supposed to blow hot air. People think they aren’t working because they are blowing cold air. Their purpose is circulating the heat from the stove not blowing hot air. If you are thinking of something that blows hot air then that would be a kerosene heater
I have found out from my personal experience that a slow moving Ceiling fan works best. I have 4 oil lanterns that I use with my Ceiling fan and the Ceiling fan circulates the heat from the 4 oil lanterns very well and I'm talking about a medium size 19ft x 14ft room roughly with the door entrance cracked open about 1 inch for ventilation. The Ceiling fan also does even better on extremely sub freezing temperature days when using my kerosene heater and entrance door cracked slight open for ventilation.
Adding to the comment below, they work via a component called 'Peltier' plates. When you apply power to the two wires it will heat one side and cool the other OR you can switch that around and HEAT one side of the plate and it generates power to, in this case drive a small motor.. and yes you can get and make these into phone chargers you place onto a hot surface (there are numerous YT vids on how-to) pretty neat!
I had a tiny electric heater that couldnt heat up the room . I had a box fan and put it behind forcing more air. And the room is toasty. It literally went from being like a fridge to nice and warm so take what you will from that.
The constant flow of air over the thermostat would have enabled the heating element to stay on longer, using power longer & costing more but giving off more heat.
@@pedclarkemobile That's possible but there are other reasons. One being the fan cooling off the heater so it can transfer even more heat to the room instead of the exhaust pipes
@@MaliohammadDesigns we are describing the same thing. The air movement moves heat energy away from the source and distributes it around the room better. I have done similar things with electric heaters. I found that with constant air blowing over the heater, the thermostat could be turned down (instead of permanently on max.) So, if the thermostat is set to say 25°C then the room temperature will actually be pretty close to the temp set on the thermostat.
Hi, we live off grid. Cold winters. On those very cold days/nights we open the stove door placing a wood stove screen over the front. Now the heat comes into the room more instead of all going out the pipe. Oh, our fan works great any place on the top, think ours is one size up from what yours are. I was always told don’t use rocks or bricks with the wood stove because they explode? Anyone else hear that? I really enjoy your videos, never lose your excitement and joy in what you are doing. Be safe, be well.
Pockets of h2O within the structure will expand and explode the containing vehicle. Thus it was always fun to throw "stream rocks" into an open fire and wait until the massive explosion, sending hot rock chips into the air so we could dodge them - hopefully.
@@Paul-hy3cu Yes it does. The best placement of the fan(s) are just behind the exhaust pipe--pointing towards to pipe. The pipe gets extremely hot and thus you want to utilize as much heat from the stove and exhaust pipe as possible.
You want to move the cold air towards the hot air, place it blowing towards the exhaust pipe. And any other fans in cold rooms blowing the air towards the stove.
lmao..... the more "potiential difference" there is between the bottom of fan(heat) & the cooling fins(cool) will cause the fan to rotate faster until it reaches it max RPM . so the fan placed offset to the right or left of the flue pipe at the rear or the firebox will be more likely to catch cooler air in its cooling fins . there is a thermal conductor at the cooling side & one under the foot of the fan base on the heating side.. the more difference between hot & cold will increase the "potiential difference" which is electricity. also the fans wont make any temps go up or down. the law of thermodynamics states [heat moves toward cold] so the fans are only helping move the heat that is produced by your heater farther away & warming more of the ambient air. if you want a hotter room you have to build a hotter fire... but if you give your room time to aclimate to the temp. of your heater (which will be faster with fans) the thermal heat will make the air a lot more comfy....and give more time for the radiant heat to heat the walls, floor, objects, ect.. and it will be time to party !
Remember, in the winter, pull warmer air up. In the summer, reverse the fan and push the air down. If you try to push hot air down, against its natural tendency to rise, it will take more work and results in cooling the air. It looks to me like you've got bricks stacked right up against the back of the stove. If that's true, don't do that. You need air surrounding the stove, so that it can be heated and rise. Don't restrict it.

no fans are needed the heat from the stove circulates the air ! all you may need is a way to pull the cold air from the floor ! that will not heat unless it is circulated ! it is simple thermal dynamics people ( heat rises ? cold drops ? ) !
I use a power fan on my fire to blow cold air onto the fireplace and it works amazingly. The amount of heat lost out the chimney instead of heating the fireplace is crazy, so by having the fan blowing cool air towards the fire not only do you move more warm air around but the cold air is sacrificed to the chimney instead of the warm air around the fireplace
Hi, thanks for the video, I hope the weather starts to warm up soon. I missed my regular dose of my favourite farmily. I will look forward to your vlog tomorrow :-)
They defintely do aid in circulating the warm air , IMO their main strength is after initial start up . I think they make heating a room up happen slightly faster , and as they cost nothing to run its a result .
Yeah, this but it's probably also a bit more efficient in using the heat that is given by the stove itself. the device get's hot and that heat is throw into the room (so basically heating the air), it does not have to spin that fast imho.
Since it’s a old house just for the winters I would put plastic over the windows to try and keep cold air out . That’s what my grandmother would do every winter then take it off during summer .
I didn't read all the comments so I apologize if someone else is already said this. If you point the fans where they blow across your exhaust pipe they will dissipate more of the heat from the pipe into the room.
I dunno if it works or not. Mine never spins that fast, but it spins at a good rate. I mostly use it to judge if the fire is hot enough or not from across the room. Slow spin, add wood. Fast spin it's ok. As someone else mentioned, they seem to be effective in helping dry out wood on top of your stove. I always have a few pieces drying up there.
I paid $200 for mine and I've also seen about 20 of these at various friends' cabins, and unfortunately they don't blow very much at all. The concept is great but in reality they barely move much air at all. To see it push a piece of paper you have to hold the sheet of paper basically right in front of the fan.
I agree. I don't think they are anything more than a gimmick. You need an electric fan to blow across the top of the stove or better yet.. a ceiling fan nearby the stove and one in your coldest room.
They're not design to blow air like a normal fan, however they do speed up air circulation in the room compared to not having one, so the heat distributes better.
Haha your house looks like my house and you look like my partners son born. Thanks for info, i think i try them out cause cost is low and electricity is not needed.
For whatever it’s worth. I have owned a Heritage Hearthstone soapstone stove for 18 years. The company claims 65% efficiency. I think that is marketing bullshit. I could have bought an attached fan for about $350 which rated poorly on reviews. My wife suggested taking a cheap table top fan ( which we already own) and point it at the stove. It was amazing. My basement living room, which barely got up to 70* now gets up to close to 80*. The warm air flows up the stairwell and keeps the main floor heated. More heat and less wood usage all because of pointing a room fan at the stove
Any time you move air, you cool it. Hot air rises where it will then stay close to the ceiling before cooling enough to fall down towards the floor, before being heated enough to rise again. One way to work with the natural convection cycle is to have a slow spinning ceiling fan that will encourage the hot air to get to the ceiling faster. That will push the hot air that is already there down towards the floor which should be warmer than what would fall naturally. It works better with smooth ceilings, as beams in the ceiling tend to make air dams that limit the hot air spreading across the room. The other thing you can do is to make sure that the fire box gets it's combustion air from an outside vent. Otherwise the fire box is using your heated air from inside the house and throwing it up the chimney. Lastly, in the room you want to be the most comfortable in, you need to insulate the outside wall. Brick walls will absorb a lot of your heat. It will absorb more heat than you could ever put into it. Unless your brick wall is facing a southern exposure where you can turn them into a solar collection wall, it's best to insulate them. You can do that with rigid insulation glued to the brick wall and then lathed and plastered over the insulation or you can frame a 2 X 4 wall in front of it and then insulate it normally. Remember 30% of your heat is lost through the ceiling. The more insulation up there the better off you'll be. The next big heat loss is through doors and windows, about 20%. Then it gets lost through the walls. The floors also remove heat, but the way you did your floors should pretty much limit that loss. We all know that heat radiates, but then, so does cold. Try closing your eyes and stand in the middle of the room. Hold your palm up and wet it. Then slowly turn around and just by the cold you feel on your palm you should be able to tell when you're facing the outside wall. Now walk toward it and as you get closer, you should feel the cold even more. Then turn around and face the inside of the room, your palm will feel warmer. Insulating the outside wall will create the thermal break needed to stop that cold from radiating into the house.
Fans do not actually lower the temperature of a room. They function by circulating air, creating a wind-chill effect on your skin which makes the room feel cooler than it actually is. The movement of air increases the rate of evaporation of sweat from your skin, thereby giving a cooling sensation. However, if you have ten fans in a small, closed room, they would not decrease the room's actual temperature. They would simply circulate the existing air, making it FEEL cooler if you're present in the room. If no one is in the room to perceive the wind chill, then the fans are essentially just circulating air without having any impact on temperature or perceived coolness.
Cold does not radiate. Your face feels the difference in radiated heat, both from a heat source AND the heat radiated from the face into the surround, this gives the perception of cold radiating.
It sounds like you do a little something everyday to stop the heat from escaping. Eventually you will get to where you need to be. Hopefully spring will arrive there soon and the cold won't be a problem.
Hi guys it was great seeing yous. Glad to see yous have fans now...once the walls have heat in them again it won't take long to heat up...it will take time. Maybe find a log company or find falling down trees and cut them for next year, as they will have to dry out...xxx
After using one for about five years, I'm skeptical they improve heating, at least in our small, open-plan house. Often times the place seems warmer throughout without the fan. My suspicion is that the fan may be cooling off the top of the stove, which is supposed to get very hot and radiate. Can't prove that. As another observed, I agree that a ceiling fan has a greater impact, forcing heat down and around.
That heat goes into the vanes of the fan which then has air blow across them taking the heat away from the vanes which keeps the vane cooler than the bottom which allows the heat to move across the peltier which generates electricity. That heat is going straight from the metal, into the fan, and then into the air as intended.
I have had an ecofan for 15 years. It definitely makes a difference, puts air into the adjacent room through a wide passageway. I can tell because the thermostat is in that room and the central heat (for the other rooms) doesn't come on as often. Only problem mine has become very noisy...
Correct. I have been using mine 13 years and it is great. The pile of bricks behind this stove is 100% wrong. They stifle air movement. The cold air rising behind is essential for these fans to work correctly.
Yes, I agree. We've always had radiant heaters and ceiling fans to bring the heat down from the ceiling. We have a slightly bigger heater and it warmed a 12 metre by 8 metre space but our winters are quite moderate.
Several other people have already pointed out that the fans work best at the back of the stove. The principal of the operation is a bimetal element at the bottom that functions by the temperature differential between the bottom being heated and cooling the top side via the cooling ribs above it! Place the fan on the perimeter of the stove directing it towards the centre will give the best results.
It’s not the bi metal that is generating the power it’s the peltier element in between the cooling fins and the stand. The bi metal curls up when the bottom gets too hot. This way it’s protecting the peltier element
Dude, to get the most out of that stove you need another strongly built (wielded 1/4” steel) box above the stove with about 9, 2” steel tubes (again 1/4” or something close if you get stock in metric sizes) wielded horizontally…back to front. This reheater will capitalize on all of that heat going straight outside. Then put a fan sucking if mounted in front or blowing if mounted in back. This will actually overheat you brick structure such that you will have to install a variable intake limiter to reduce the fuel burn rate. Put it on legs so that the reheating box (with the tubes) is about 2.5’ above the stove top. This will drastically reduce your wood consumption and almost triple your heat output simultaneously. If you don’t wield neatly you could find a guy in your berg who can fab this up in about 2-3 hours. Then you just need to paint it with height temperature enamel from a rattle can and get some more stove pipe and reroute your exhaust. Best,
Convected heat rises whichever direction you blow it, so it all just ends up on the ceiling anyway along with the heat that rises directly above the fire, and as the moving efficiency of these fans is barely enough to push air a few inches, it goes nowhere but up. If you want heat directed horizontally across the room in a straight line however, you need to point the door glass in that direction and let radiation warm that cool corner or dry your laundry. But stoves are fixed, so whatever you want to heat has to be moved in line with the glass - or open door - instead.
Lol you want to charge your phone from the fire I suggest purchasing a BioLite stove it's got a thermocoupler built into it to turn the fire into electricity , nice fans though use them in my hot tent for winter camping, don't put them Ever in front of the pipe though unless you want to turn them into trash lol .
I have 1 fan on my Morso 06 stove. I would say probably at least15% improvement. However these fans arent super-reliable and I had to buy a new Pelltier device for mine after 18 months and also the motor had stiffened up and needed some penetrating lube to get it going properly again.
I believe the thermometer works better in two places, right at the top of the stove, so you will know if stove is too hot, and above the battle so you know if the temp is too low or too hot. This way you control for the stove not overheating, and above battle you can close the battle and see if the temp is changing. What we want to avoid is burn the house or create creosote what will eventually also burn the house. I went ahead and just got two thermometers and use in both spots, make sure to compare it to a laser hand held thermometer to see the accuracy of the magnet ones
I see you have piles of bricks on one side and at the rear this prevents convection (rising air) all sides should be clear to get maximum heat from the burner.
I think the bricks are partly placed like little shelves and a log store. Some people put bricks against the stove to absorb heat and radiate it later after the fire goes out, but usually you just stoke it up to last through the night.
I have found these fans to be useful for one thing.. quickly drying wood that has snow/ice on it. I place the wood on top of firebrick, on top of the stove and point that fan at it. Outside of 18" I think there pretty useless.
One of the most effective fans I've seen are those that are built into the stove itself. It takes the heat from around the fire box itself. They are often part of what's called zero clearance fire places. Another good fan is one that is built into the stove pipe itself. it can be bought separate and installs in the flue pipe. But be aware that that type of fan is efficient enough to actually cool the escaping smoke going up the chimney. This results in a need to clean the stove pipe of a bigger creosote build up that you wouldn't get if the escaping gases were hotter.
If the stove is using the exterior wall existing chimney, a good portion of the heat is just heating up the outside wall. A more centrally located stove (not up against a wall), free standing with a chimney pipe going directly up through the roof is ideal. That stove is big enough. Being centrally located (all sides exposed to the room), it would work well. Right now, it's just heating up an exterior wall ...like a traditional fireplace.
I think what's more important than moving the air is pulling more energy from the exhaust pipe with a pipe mounted fan. So kire heat stays in the room.
I am about to get one but would say that they have to work in theory just by the fact they move the air. Without a fan a lot of the heat will rise into the chimney. It is a question of spreading the heat.
You actually could charge your phone if you wanted a nerdy project. You’ll need some TECs thermoelectric couplers (I think). This video explains it a bit (it’s nerdy) ruclips.net/video/YWUhwmmZa7A/видео.html. They are what’s on those fans. And am sure they’re only designed to make air circulate around a room to avoid hot spots, they won’t blow hot air as such.
I will definitely check this out! 🤔 I love tinkering around 😊 I am sure they are only for improving circulation of the air! I want to find a better way to harwest the heat from the chimney
I didn't see the fans blowing your hair back like fabio! so they must be like mine.i feel no air flow at all from it.is this just mine or can you actually feel air movement let me know maybe mine is just expensive junk.
You seem to have a double-walled chimney pipe. that thermometers don't work on those. Put it instead on the flat top. For the double-walled pipe, you need type where you drill holes and put in probe stick inside about 12 inches up from stovetop.
I have a large cooking/surface area on my wood burning stove. I put it in the middle and not towards the back because these fans don't really have any strength. It's kind of a waste. I've even put on of them at the entrance of the stove facing in, to see if I can get the fire hotter. It didn't work AT ALL.
I have a couple similar fans that clamp onto the chimney pipe so the top of my stove is clear for a pot of water the fans help move the heat pretty nice
What kind of test is this? You want to find out if the ventilators are spinning, or you want to know if they have any effect on heating up the room? You have to check the heating with and without the fans. I can only see they are spinning - but does it help for the temp? I bought two of them and the next day I returned them to the shop. For me the effect of the fans was noticeable at max 50 cm away from my fireplace. They are just to small to make any difference. Good stuff for the vendors, but bad for your wallet.
Is it a gas central heating boiler or the cooking stove? It will work with any hot metal surface on brick it doesn't get enough heat transfer for the little heat generator to create electricity, I have seen them work on a pan as well so it should!
A friend of mine has one of these, unfortunately it stopped working and my friend is looking for an answer to why it stopped working? Any idea guys? Could it be that the eletrons in the TE materials have run out? Or what else? Thanks.
I know the door to the hallways is lacking but still there sould be more warmt. I had a woodcabin. It was so cold there but the stove really did the trick. it was not isollated at all, neither walls, floors or roof. The floors was just levels of planks. Still be got it to 27 degrees wich was again too hot.
As someone else has said bricks at the rear of the stove isn't good as the hot air can't radiate from there, also all the brickwork acts like a heat sink good insulation is a must
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!
One candle gives out approximately 30 Watts of heat energy. If a 1000 watt electric heater (1kw) heats the room enough, then thirty three good tealight candles should also heat that same room. Those terracotta pot/candle heaters are good at collecting/storing heat to radiate it, especially if you're sitting close to one, they prevent the heat from rising straight to the ceiling. Unfortunately tealight candles aren't that cost effective when so many are needed. I found (over the years) that pretty much all energy is priced accordingly... per kW. I think it's more about efficiency than what source we use; how we use that energy, A Clark.
I've had mine for 5 years. Works great on my wood stove. I just put a shelf on my buddy heater and now I use the fan on the buddy heater and it works great as well.

That depends on the type of rock or brick. As @franciskelly mentioned. Lava rocks and I think maybe most insigneous rocks won't explode.
You can buy fire brick for this or mold bricks from a specific type of firesafe cement. A lot of people have done this to make outdoor pizza ovens.
I have a similar situation with just one fan, but I face the fan to blow cold room air against the hot 🔥 chimney. I think it works better.
I believe the fans should be on the back of the stove so they blow the warm air across from the stove
It doesn't matter if they are in front as they will pull the hot air through the blades rather than push it. Hope this helps.

My basement living room, which barely got up to 70* now gets up to close to 80*. The warm air flows up the stairwell and keeps the main floor heated. More heat and less wood usage all because of pointing a room fan at the stove
How abut putting a cheapo box fan at the most distant line-of-sight place down the hallway and aim it at the stove. Quickest heat mixing location
Genius
Any time you move air, you cool it.
Hot air rises where it will then stay close to the ceiling before cooling enough to fall down towards the floor, before being heated enough to rise again. One way to work with the natural convection cycle is to have a slow spinning ceiling fan that will encourage the hot air to get to the ceiling faster. That will push the hot air that is already there down towards the floor which should be warmer than what would fall naturally.
It works better with smooth ceilings, as beams in the ceiling tend to make air dams that limit the hot air spreading across the room.
The other thing you can do is to make sure that the fire box gets it's combustion air from an outside vent. Otherwise the fire box is using your heated air from inside the house and throwing it up the chimney.
Lastly, in the room you want to be the most comfortable in, you need to insulate the outside wall. Brick walls will absorb a lot of your heat. It will absorb more heat than you could ever put into it. Unless your brick wall is facing a southern exposure where you can turn them into a solar collection wall, it's best to insulate them. You can do that with rigid insulation glued to the brick wall and then lathed and plastered over the insulation or you can frame a 2 X 4 wall in front of it and then insulate it normally.
Remember 30% of your heat is lost through the ceiling. The more insulation up there the better off you'll be.
The next big heat loss is through doors and windows, about 20%.
Then it gets lost through the walls.
The floors also remove heat, but the way you did your floors should pretty much limit that loss.
We all know that heat radiates, but then, so does cold.
Try closing your eyes and stand in the middle of the room. Hold your palm up and wet it. Then slowly turn around and just by the cold you feel on your palm you should be able to tell when you're facing the outside wall. Now walk toward it and as you get closer, you should feel the cold even more. Then turn around and face the inside of the room, your palm will feel warmer.
Insulating the outside wall will create the thermal break needed to stop that cold from radiating into the house.
"Any time you move air, you cool it." This is 100% incorrect!!
It’s not the cold air falling, it’s the warm air rising.
Fans do not actually lower the temperature of a room. They function by circulating air, creating a wind-chill effect on your skin which makes the room feel cooler than it actually is. The movement of air increases the rate of evaporation of sweat from your skin, thereby giving a cooling sensation. However, if you have ten fans in a small, closed room, they would not decrease the room's actual temperature. They would simply circulate the existing air, making it FEEL cooler if you're present in the room. If no one is in the room to perceive the wind chill, then the fans are essentially just circulating air without having any impact on temperature or perceived coolness.
Cold does not radiate. Your face feels the difference in radiated heat, both from a heat source AND the heat radiated from the face into the surround, this gives the perception of cold radiating.
@@joelcaldwell1635they have been shown to give approx 14 % improvement in BTUs per unit of fuel consistently.
It sounds like you do a little something everyday to stop the heat from escaping. Eventually you will get to where you need to be. Hopefully spring will arrive there soon and the cold won't be a problem.
Yeah spring is around the corner 😊❤️
Hi guys it was great seeing yous. Glad to see yous have fans now...once the walls have heat in them again it won't take long to heat up...it will take time. Maybe find a log company or find falling down trees and cut them for next year, as they will have to dry out...xxx
Thank you! 😊❤️ We will find some wood in spring now so it can dry out for next season! 😁
@@DoBeDiff I guys i sent yous a message on Instagram just because I was worried about yous...from Scotland xx
After using one for about five years, I'm skeptical they improve heating, at least in our small, open-plan house. Often times the place seems warmer throughout without the fan. My suspicion is that the fan may be cooling off the top of the stove, which is supposed to get very hot and radiate. Can't prove that. As another observed, I agree that a ceiling fan has a greater impact, forcing heat down and around.
That heat goes into the vanes of the fan which then has air blow across them taking the heat away from the vanes which keeps the vane cooler than the bottom which allows the heat to move across the peltier which generates electricity.
That heat is going straight from the metal, into the fan, and then into the air as intended.
I have had an ecofan for 15 years. It definitely makes a difference, puts air into the adjacent room through a wide passageway. I can tell because the thermostat is in that room and the central heat (for the other rooms) doesn't come on as often. Only problem mine has become very noisy...
Just happy your warmer !
Thank you! 😊❤️
In the late 1800s they had chistmas decorations that were made from brass that moved from heat of small candells .
Yup, they are still around. Search for "candle carousel".
We also want to buy one and I did some research on it and found that it is better to place it behind / next to the pipe, not in front of it.
Thank yoi for the info, I will try that, I was moving around to see where its better 😊❤️
@@DoBeDiff hope it works! We first have to check if there will be enough space as our woodstove is a bit smaller than yours.
@@BrendaLelie they are quite small! Should be no problem, like 5cm in width! 🤔
Correct. I have been using mine 13 years and it is great. The pile of bricks behind this stove is 100% wrong. They stifle air movement. The cold air rising behind is essential for these fans to work correctly.
You need to get a couple of ceiling fans to move the hot air from the ceiling and get everything warm.
Yes, I agree. We've always had radiant heaters and ceiling fans to bring the heat down from the ceiling. We have a slightly bigger heater and it warmed a 12 metre by 8 metre space but our winters are quite moderate.
@@williamwallace9620 My living room fan is almost right above my wood stove. Just switch it to reverse, warms up my whole living room!
Several other people have already pointed out that the fans work best at the back of the stove. The principal of the operation is a bimetal element at the bottom that functions by the temperature differential between the bottom being heated and cooling the top side via the cooling ribs above it! Place the fan on the perimeter of the stove directing it towards the centre will give the best results.
It’s not the bi metal that is generating the power it’s the peltier element in between the cooling fins and the stand. The bi metal curls up when the bottom gets too hot. This way it’s protecting the peltier element
Dude, to get the most out of that stove you need another strongly built (wielded 1/4” steel) box above the stove with about 9, 2” steel tubes (again 1/4” or something close if you get stock in metric sizes) wielded horizontally…back to front. This reheater will capitalize on all of that heat going straight outside.
Then put a fan sucking if mounted in front or blowing if mounted in back. This will actually overheat you brick structure such that you will have to install a variable intake limiter to reduce the fuel burn rate.
Put it on legs so that the reheating box (with the tubes) is about 2.5’ above the stove top.
This will drastically reduce your wood consumption and almost triple your heat output simultaneously.
If you don’t wield neatly you could find a guy in your berg who can fab this up in about 2-3 hours. Then you just need to paint it with height temperature enamel from a rattle can and get some more stove pipe and reroute your exhaust.
Best,
Sure, let me just gather up all of the materials and welder and whip it right up
do you have an image or example of this?
Convected heat rises whichever direction you blow it, so it all just ends up on the ceiling anyway along with the heat that rises directly above the fire, and as the moving efficiency of these fans is barely enough to push air a few inches, it goes nowhere but up. If you want heat directed horizontally across the room in a straight line however, you need to point the door glass in that direction and let radiation warm that cool corner or dry your laundry. But stoves are fixed, so whatever you want to heat has to be moved in line with the glass - or open door - instead.
We use a ceiling fan really helps warm the room.
I'm looking at these for passive cooling for my supercharger between races 😅
You can trim your nails on the fans as an added bonus
there is a little tiny camp stove, like heat 1 cup of water small, that you heat w wood and you can charge your phone,
Lol you want to charge your phone from the fire I suggest purchasing a BioLite stove it's got a thermocoupler built into it to turn the fire into electricity , nice fans though use them in my hot tent for winter camping, don't put them Ever in front of the pipe though unless you want to turn them into trash lol .
I have 1 fan on my Morso 06 stove. I would say probably at least15% improvement. However these fans arent super-reliable and I had to buy a new Pelltier device for mine after 18 months and also the motor had stiffened up and needed some penetrating lube to get it going properly again.
I put a powerful 12 inch mains fan pointed at the stove, it heats the room better than without, its a strong fan mind.
As long as the walls are not insulated, it is normal not to have enough heat. And anyway the stove is too small for a kitchen and a living room.
I really hoped for a proper review but all I got was daft music noise.
You need outside combustion air, that stove suck all the heat out the chimney through the air intake that's from your room
Cool review... thanks!
Want to watch all your series but don’t know what sequence they come in . I would like to start at No 1 the beginning and work through xx
Here is the playlist from the beginning just skip what you already watched 😊❤️: ruclips.net/p/PL_NOQIOI8_jFtfg-okg5vcFANi_T-kCBH
I believe the thermometer works better in two places, right at the top of the stove, so you will know if stove is too hot, and above the battle so you know if the temp is too low or too hot. This way you control for the stove not overheating, and above battle you can close the battle and see if the temp is changing. What we want to avoid is burn the house or create creosote what will eventually also burn the house. I went ahead and just got two thermometers and use in both spots, make sure to compare it to a laser hand held thermometer to see the accuracy of the magnet ones
I see you have piles of bricks on one side and at the rear this prevents convection (rising air) all sides should be clear to get maximum heat from the burner.
I think the bricks are partly placed like little shelves and a log store. Some people put bricks against the stove to absorb heat and radiate it later after the fire goes out, but usually you just stoke it up to last through the night.
Will purchase again. I have always trusted the Lasko brand.
We have one of those little fans, it works greats, we also have ceiling fans.
I have found these fans to be useful for one thing.. quickly drying wood that has snow/ice on it. I place the wood on top of firebrick, on top of the stove and point that fan at it. Outside of 18" I think there pretty useless.
One of the most effective fans I've seen are those that are built into the stove itself. It takes the heat from around the fire box itself. They are often part of what's called zero clearance fire places. Another good fan is one that is built into the stove pipe itself. it can be bought separate and installs in the flue pipe. But be aware that that type of fan is efficient enough to actually cool the escaping smoke going up the chimney. This results in a need to clean the stove pipe of a bigger creosote build up that you wouldn't get if the escaping gases were hotter.
If the stove is using the exterior wall existing chimney, a good portion of the heat is just heating up the outside wall. A more centrally located stove (not up against a wall), free standing with a chimney pipe going directly up through the roof is ideal. That stove is big enough. Being centrally located (all sides exposed to the room), it would work well. Right now, it's just heating up an exterior wall ...like a traditional fireplace.
But they have double brick walls with the air space between so that make a diferentes.
and your point is?
@@gryphonennis1002 If you've ever relied solely on wood stove heat, this wouldn't perplex you.
I think what's more important than moving the air is pulling more energy from the exhaust pipe with a pipe mounted fan. So kire heat stays in the room.
Should point them at the chimney to blow the heat off it and into the room. The chimney pipe is on it's way to taking heat out of the house anyway.
Why u have bricks behind stove does it help give off more heat
It works like a heat battery and stores the heat and release it after the stove is all cold the bricks are nice and warm.
@@DoBeDiff Roger that good idea
I am about to get one but would say that they have to work in theory just by the fact they move the air. Without a fan a lot of the heat will rise into the chimney. It is a question of spreading the heat.
Try reserching the work done in investigating radient heat.
Hang up a blanket by your leaky door. That will stop a lot of wind from coming through.
These fans really help to eliminate the cool spot often felt at floor level . They don’t blow in my opinion the just circulate the warm air .
You actually could charge your phone if you wanted a nerdy project. You’ll need some TECs thermoelectric couplers (I think). This video explains it a bit (it’s nerdy) ruclips.net/video/YWUhwmmZa7A/видео.html. They are what’s on those fans. And am sure they’re only designed to make air circulate around a room to avoid hot spots, they won’t blow hot air as such.
I will definitely check this out! 🤔 I love tinkering around 😊 I am sure they are only for improving circulation of the air! I want to find a better way to harwest the heat from the chimney
@@DoBeDiff then perhaps heat exchanger is the way. I’ve seen a system in Latvia where they pumped hot air around the whole house.
I didn't see the fans blowing your hair back like fabio! so they must be like mine.i feel no air flow at all from it.is this just mine or can you actually feel air movement let me know maybe mine is just expensive junk.
They are okay! They don't blow insanely fast but they definitely move the air a lot! They helped a lot since we got them! 😀
When I use a fan with the wood burner, I point it at the flue.
You seem to have a double-walled chimney pipe. that thermometers don't work on those. Put it instead on the flat top. For the double-walled pipe, you need type where you drill holes and put in probe stick inside about 12 inches up from stovetop.
It's a good idea however if u adjust air and clean out all the bits and Bob's then open door heat will rise increasing in front of fan maybe..
The heat comes from the glas point them outwards so the heat blows from glas to the middle of room
I have a large cooking/surface area on my wood burning stove. I put it in the middle and not towards the back because these fans don't really have any strength. It's kind of a waste. I've even put on of them at the entrance of the stove facing in, to see if I can get the fire hotter. It didn't work AT ALL.
I have a couple similar fans that clamp onto the chimney pipe so the top of my stove is clear for a pot of water the fans help move the heat pretty nice
I got them from a store called Princess Auto I'm not sure where you live but we have those stores in Canada
The instructions on mines says to put them behind (not the stove) closer to the pipe
Yeah they work better, but I have no space behind the pipe! 😁❤️
Hope you are staying warm
@@DoBeDiff SO put them as far back as possible and point them towards the exhaust pipe.
What's a good fan for a brick fire place?
I have one. Found it causes chimney to stop up frequently. So I don't use it anymore.
They work far better on a wood burning stove instead of a wood fire place. Insulation works both ways for keeping heat in or out.
What happens if you put one of this inside an oven? Do you get convection?
Hahaha I mean it in a good way you and your family stay safe
What kind of test is this?
You want to find out if the ventilators are spinning, or you want to know if they have any effect on heating up the room?
You have to check the heating with and without the fans. I can only see they are spinning - but does it help for the temp?
I bought two of them and the next day I returned them to the shop. For me the effect of the fans was noticeable at max 50 cm away from my fireplace.
They are just to small to make any difference.
Good stuff for the vendors, but bad for your wallet.
Will this also work on a gas stove?
Is it a gas central heating boiler or the cooking stove? It will work with any hot metal surface on brick it doesn't get enough heat transfer for the little heat generator to create electricity, I have seen them work on a pan as well so it should!
A friend of mine has one of these, unfortunately it stopped working and my friend is looking for an answer to why it stopped working? Any idea guys? Could it be that the eletrons in the TE materials have run out? Or what else? Thanks.
1:20 you might want to get several thermometers and put them in different locations on the stove
Love watching you all! What happened to the barrel stove? I missed that episode. The new stove looks great!
I know the door to the hallways is lacking but still there sould be more warmt. I had a woodcabin. It was so cold there but the stove really did the trick. it was not isollated at all, neither walls, floors or roof. The floors was just levels of planks. Still be got it to 27 degrees wich was again too hot.
I've read you put those in the back of the stove.
Yes put back more if your gona cook on top. But it looks nice.
This is definitely red dead music. Lol. Thanks for the video.
I think it's more of a conversation piece than anything
Τελειο!
Cold air or hot air
As someone else has said bricks at the rear of the stove isn't good as the hot air can't radiate from there, also all the brickwork acts like a heat sink good insulation is a must
I have a twin rota fan and it certainly does work.
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!
One candle gives out approximately 30 Watts of heat energy. If a 1000 watt electric heater (1kw) heats the room enough, then thirty three good tealight candles should also heat that same room.
Those terracotta pot/candle heaters are good at collecting/storing heat to radiate it, especially if you're sitting close to one, they prevent the heat from rising straight to the ceiling.
Unfortunately tealight candles aren't that cost effective when so many are needed.
I found (over the years) that pretty much all energy is priced accordingly... per kW.
I think it's more about efficiency than what source we use; how we use that energy, A Clark.
My fan info says to put the fans towards the rear of the stove.
Good luck.
Dont even have a wood stove or fire place. Not sure why I watched this video but it was cool
have to ask because they come with 2 blades 3 blades , 4 blades , 5 blades and 7 blades why is there no rating on if less or more blades work better
I have one. These are to look at and admire. They do nothing to improve your home's heat distribution. A big ceiling fan is the way to go.
What is the music playing ? Great guitar, so beautiful
How much electricity could be produced in this way?
OO...that's a cold shack. Happy to have a small shack.
Any idea what maximum temperature these can handle before the electric motor fails?
Had no problem going up to 800°f. Still all works for two seasons now!
@@DoBeDiff Thanks, I will have to convert that to Celcius being in Oz.
