one word of caution...do not refill the can when its hot...there have been many fires in boats that use alcohol burners because the hot can ignited the fresh alcohol when it was poured in...always have a 2nd can thats cold with alcohol in it to replace your just used can. then just swap as each runs out
Directing the hot air through concrete blocks creates thermal mass without sacrificing any heat. I got that idea from a couple videos you made years ago with your concrete block rocket stove and your tuna can stove. It has worked very well heating my small shed the last couple winters - thank you for that!
That's a great idea, the bricks will help disperse the heat as well. I think you can get around 2 to 3 hours of continous burning if you use the toilet paper burner, not sure how is called, is where you place a roll of toilet paper inside medium size new paint can, stuff the paper fill it with alcohol and that thing burns for hours. Great tutorial Semper Fi
I put as many fire bricks as I can on a Coleman propane double burner stove and fire it up. Ive never timed it but you can run it on low for hours. After the bricks heat up they’ll continue to heat a room for a few hours after you run out of fuel. You can run it for days on a 15 pound cylinder.
Very cool emergency heater. I have already thought about increasing the BTUs and length of burn time. I have a nice size pile of fire bricks and a 7" tee. I also have a 6" pipe cap which will easily fit inside the 7" tee and hold more alcohol. I have an ethanol still and fuel permit so making 95% ethanol is pretty easy. It runs my electric generator.
We have moved to a house, that has no heat. Needs lots of work. We have several electric heaters. One is an electric wall heater. I took a terra cotta pot, drilled a few more holes in the bottom, and it was crazy the difference it made in the affect of the heater! After all the heaters I have sat up this winter, I have learned, too much air flow, you lose the heat. The more surface you have, with continuous,but slow, air movement, the better it heats the room. No matter what source of heat you are using.
I like the idea. I already use that hvac piece for part of a rocket stove I built but I might use something like this for a power outage. Too bad won't have electricity for the fan portion to blow the heat to the area. EDIT: although I do have a battery operated portable fan I can always do that too!
That's really nice config, thanks for share. You can even consider use a fan powered with a peltier celd that will be totally awesome...Or puting like heat source a candel into a pot full of oil you'll have hours and hours of heat transfered. Thanks allways for the inspiration, keep in the good Creative EnJoy!! Cheers mate! Blessings
I’ve heard it will last longer if you ball up a rag in the can I made a penny can stove similar to this and it burned over two hrs. Depends on how much alcohol you use I guess
Great job, I love this idea. Maybe you could use some stainless steel mesh to keep the flame out of your air tube? I also considered using a wick in the alcohol burner part to regulate the burning of you fuel.
I've seen this question being asked in the commets a few times already, but he never answers it. You'd think it would have been something he mention in the video, it's a very obvious question that folk would ask when seeing this.
@@michellelaclairDenatured alcohol and isopropyl alcohol are cheaper than kerosene. The best solution is to not use a cat food tin. Build a small toilet paper heater in a quart-sized empty paint can and use that filled with 70% or 91% isopropyl alcohol or denatured alcohol And you'll have a stove that will last you many hours and hasn't even used up your entire 32 oz bottle of isopropyl alcohol
I think this is a great simple effective design, my only issue is that isopropyl alcohol is very expensive so as an emergency for a few hours if you had a gallon of it stored just incase then fine but you would need loads which would be very expensive, it would cheaper to run a small generator and power an electric fan heater.
Had the same thought. I was wondering if a Buddy Burner in a veggie can (4-6 hour normal burn time) might work in something like this. The flame might not be a hot , but should yield similar results on a lower budget. It would produce some soot, so some small amount of ventilation might be required.
I've bought all the supplies & tried the other alcohol heaters you've recommended. Only problem is the smell of the alcohol permeates the room & lasts longer than the heat. I personally can't even stay in the room for long with the burning alcohol smell. It's awful. Wish you could find something to suggest that didn't create a smell throughout the room. If anyone knows of something, please share.
Penny stove , or similar jet burning type stove might burn better and have less smell, I have one that burns like a torch once fully going and never noticed smell.
Denatured alcohol says it burns smokeless and odorless. Be cautious as this may burn differently than isopropyl alcohol. You may want to try a can with a smaller diameter top. This will decrease the surface area that is burning. The other option would be to use a wick and cover the top with tin foil or other metal, obviously you need to cut a small hole for the wick to come through.
Use a clean paint can, remove the tubes of about 4 rolls of toilet paper, squish together and put into the bottom of the can. Pour the alcohol over it then light it, a paint can that holds 4 large bottles of alcohol will burn about 8hrs If you put two rows of tp, your flame will be much smaller, but you can extend the amount of time it keeps going. I might add, the can does not need to sit on concrete or heat absorbing material. The alcohol keeps the can cold.
I need a setup similar to this just near my front where my front door is on especially colder than usual days since it can be very drafty.Preferably would like to set it up as low as possible since the coldest air sinks lowest along the floor however i might need similar step.Where did you get the metal step stool?Thanks
i'm not sure - but i literally just finished filming this running on a green bio fuel. video will be posted soon. it put out a slightly higher heat (just a little higher *250F - worked great!)
I forgot to mention that I also added a small cooking grate over the 2nd tuna can to place the fan on, so it heats up the heat sensitive metal on the base of the fan. There's also a short video on that link to show how the little fan works. It is just perfect for this wonderful idea that will surely save lives when the SHTF! Thanks again!
it depends on your situation. it's safe in some indoor scenarios but not in others. depends on where you set it up and how you use it. how big of an area it is in. is area drafty. is area ventilated. stuff like that. i used it for quite a while during filming and it worked fine. i have co detector and 3 smoke detectors in house and none ever go off.
Desertsun, I have a problem I hope you can help me. I have a solar hot water baseboard heating system setup, one 4 ft x 8 ft solar hot water panel circulating hot water into 100 gallon insulated tank outside here in New Mexico. Then I have a second pump circulating water through baseboard heaters. I haven't even used it yet because I can't get the water temperature above 95°. F. I really don't want to have to add a second solar panel and a second pump, it will just complicate things too much. It takes up too much space and the one panel May shade the other panel. I would like to get the 100 gallons water temperature up to around 150 to 160° f. Is there a way you can suggest that I can do this? I live at 7,000 ft so winter temperatures at night can typically range between 15 to 30° Thank you.
A heat activated fan will work. Since the fan is mounted in the back you can power the fan with a separate candle an not worry about any draft bothering the flame.
hi there. they call this type of tee a stove pipe tee. they are made of cold-rolled steel and come painted black. they list them lowes website as 'black steel stove pipe tees'.
hi. i didn't officially time it but i think it was 30 to 40 minutes on a fill up. for some reason the 91% seemed to go a little longer. (i was doing half cans and getting 15 to 20)
You must of burnt off the galvanize first right? Or is that a stove pipe?. I did one today with a 4" T and used a Trangia Alcohol Stove with 91%. Started out Awesome, kicking out heat, then flames were coming out the front radical like a jet car. I use a quick blast of a fire extinguisher to put it out. Took some the galvanized coating off.
hi there. this one is made using stove pipe (so it's not galvanized). sounds like you might have been running the fan too fast. it needs to be a slow speed fan or the flames can come out the front. 👍🔥 (could also be the stove you used as the fuel source. that might be too powerful). if you tweak your design a little you'll probably get it working good.

You coming up with so many models that is becoming confusing.test all of them properly in a full 48 hours graphics about the real temperature on the room and let us known the winner in safety,efficacy,economy and simplicity. Good video,keep it up!👌
hi. i really focused on air heaters this winter (partly because of the situation that happened in texas last year). many of my heaters can be used even when the power grid is down
hi. since it's just a small tin of alcohol burning it only produces very small amounts of undesirable by-products. not enough to be an issue (not even close). you'd have to burn maybe 10 cans at the same time for issue to arise. i have more problems when i burn 2 incense sticks or cones at the same time). btw - because some people are sensitive to any fumes at all i recently ordered some ethanol (ethyl alcohol) to use in some upcoming projects. it burns 100% fume and soot free. costs 3 to 4 times as much but 'what can you do'. you got to pay what it costs.
Just imagine if half the homes in this nation was using a little furnace like this most of the gas and electric utilities in this nation would be filling bankruptcy over night. Actually the best fan for this would be a fan that operates off of the heat itself you can get one on amazon. Thanks for this info.
seems like i was actually getting longer burn time with the 91%. about 5 minutes longer than the 70%. (probably because there is 30% other stuff in the 70%). i was getting a maximum burn time of 40 mins with the 91%. btw you can use ethanol and bio ethanol in this unit too. that lasts even longer than isopropyl alcohol (and it's very clean and green). if interested i have a video on that too
@@panoskar8952 I doubt tuna cans are standard sized and I know the quantity is not important here, but a tuna can I grabbed off the shelf was about 3 3/8" diameter and 1.5" high so about 13.5 cubic inches which is about .22 liters or 7.4 ounces. So, a gallon of fuel would last about 600 minutes, using 35 per tin as a measure, or 10 hours. In Canada, the fuel is about $50/g so 10 hours of heat for $50 or $5/hr. This seems somewhat feasible if you need heat in a place where there is no method of getting it. You can run a 1500w electric heater for a month for $50, so you're not going to use this method when electricity is available, I wouldn't think. It is likely the fuel source is much less expensive, normally, and in other countries, so all of this is strictly for my location in eastern Canada, FWIW.
@@owenparker6651 Thanks for that answer as I was about to jump on that knucklehead asking how much a tuna can would hold! lol Incidentally, a 32 ounce isopropyl alcohol at the dollar store in virginia is a dollar so that's 4 dollars a gallon.

Some of those 4” desk fans come with usb plugs too, which you can most likely run off of a power bank in case of emergency as well.
good point 👍
A TEG generator! Find the sweet spot on the duct.
You can solar charge a usb battery and run a usb fan much cheaper.

Nice setup. The only thing I would add is a nice handle on the top so you can lift it with one hand and put out the fire with the other.

About how long does the tuna can of fuel last using the fan?
I was wondering the exact same thing! I think using something bigger made of metal would work, but might create too big of a flame.
Maybe you could use some sort of a drip feed
I’ve heard it will last longer if you ball up a rag in the can I made a penny can stove similar to this and it burned over two hrs. Depends on how much alcohol you use I guess
40-50 minutes
put a pot upsidedown over flame to create mass battery then blow air on fan. youll get way more usable heat for less energy expense
A great idea! That box fan, set back a few feet might have the same effect but move more air.
A square or rectangular T unit would have more utility.
If the top was flat, you could set a pan on it for cooking.
Good idea, I wonder if you could use the inside like a small toaster oven.

A heat activated fan will work. Since the fan is mounted in the back you can power the fan with a separate candle an not worry about any draft bothering the flame.
Turn fan around, seems blowing air down towards flame. Now, get two fans on each end, facing out, blowing away from flame
Can't do that,it will melt the fan.

I have seen some put cotton balls in the alcohol. What do you think?
hi. i wouldn't use cotton balls for this one
I was planning to this but you beat me to it. 😀👍
How long does the tuna can of alcohol last ? Thanks for your time
hi there. about 30 mins (more or less)
Excellent idea. Can I ask how long did each refill of can last and how much was used in mls
i usually get about 30 mins. but it will depend on the exact can that you use.
@@desertsun02 OK thanks was it 100mls at a time you'd use ?
in an emergency where do you get the electricity to power the fan??
hi. in case of no electricity, i'd use a DC fan hooked to battery or solar panel. there may be a way to use a heat powered stove fan as well
@@desertsun02 actually one of those "heat fans" propelled by the heat alone might work. Just happen to see them on Ebay last night.
@inkey2 if interested, my last 3 videos use those heat powered stove fans. i like them a lot. just bought 2 more (one bigger and one smaller)
How long does it burn
Just imagine if half the homes in this nation was using a little furnace like this most of the gas and electric utilities in
this nation would be filling bankruptcy over night. Actually the best fan for this would be a fan that operates off of the
heat itself you can get one on amazon. Thanks for this info.
Did you calculate how long a "tuna can" full of the 91% would burn?
seems like i was actually getting longer burn time with the 91%. about 5 minutes longer than the 70%. (probably because there is 30% other stuff in the 70%). i was getting a maximum burn time of 40 mins with the 91%. btw you can use ethanol and bio ethanol in this unit too. that lasts even longer than isopropyl alcohol (and it's very clean and green). if interested i have a video on that too
Very interesting indeed. Any idea how long a tuna can full of alcohol might last?
my guess is 30 to 40 minutes (but you could run it five minutes at a time and stretch the time). it heats an area fast
@@desertsun02 This seems very feasible for a cabin or cottage. Thanks for innovating and sharing!
@@desertsun02 how much liquid does the tuna can hold?
@@panoskar8952 I doubt tuna cans are standard sized and I know the quantity is not important here, but a tuna can I grabbed off the shelf was about 3 3/8" diameter and 1.5" high so about 13.5 cubic inches which is about .22 liters or 7.4 ounces. So, a gallon of fuel would last about 600 minutes, using 35 per tin as a measure, or 10 hours. In Canada, the fuel is about $50/g so 10 hours of heat for $50 or $5/hr. This seems somewhat feasible if you need heat in a place where there is no method of getting it. You can run a 1500w electric heater for a month for $50, so you're not going to use this method when electricity is available, I wouldn't think. It is likely the fuel source is much less expensive, normally, and in other countries, so all of this is strictly for my location in eastern Canada, FWIW.
@@owenparker6651 Thanks for that answer as I was about to jump on that knucklehead asking how much a tuna can would hold! lol Incidentally, a 32 ounce isopropyl alcohol at the dollar store in virginia is a dollar so that's 4 dollars a gallon.
awesome video thank you!! What alcohol work better. 70 or 91?
thanks! 70 seemed to burn bluer but 91 seems to last longer (both a surprise to me).
How long does a tuna fish can full of alcohol last?
hi. about 25 to 30 mins
How large of an area are you covering?
hi. the front room in my house is a couple hundred square feet
How long does a tuna can worth of alcohol last??
hi. abut 30 mins
Great idea! About how long does it burn
thanks! about 30 to 40 minutes
humidity factor ?
Love the options
if you use DC fan then it's totally off-grid. (and they sell lots of smaller dc powered fans these days)
A little better fuel is HEET gasoline treatment. It burns hotter and cleaner. That's what I found on my heaters
Can you use grey blocks ?
hi. if you mean grey stone bricks that are the same size, i'd say yes.
What’s the burn time of the tuna can?
i usually get 25 to 30 minutes. i just recently found a larger tuna can (so i'll be try that soon).
