Chickens love them lol

@zs6deb, Hey thanks for the comment. Yes, that was the hope that if we could help just one person or family avoid disaster it is worth it. I'm actually surprised no one has added another video improving on this one, this was just supposed to get the ball rolling. So, thank you for your kind words. Happy, safe, building.

@Mancavedweller1 Thanks for the comment. Yeah it comes in pretty hot. We kept the air flow at a maximum without sounding irritating like a hair dryer. You can adjust the temperature by decreasing the flame in the furnace which is what we recommend. It does feel awesome to be able to go really hot if you want to but also have the ability to tone down the flame and save on fuel if you want to. We are actually working on a model about a third of the size for smaller buildings. updates when that happens... Happy building.

@@BradShows I think some kind of valve that controls flow rate exists - I'm still a little concerned about the oil viscosity could change due to temps etc. Maybe that could be added?

@gsdggasgs1799, Thanks for the comment, yeah, it works great... a lot of heat. We are working on a smaller model should be complete next winter, about half the size. Happy building.

@@gsdggasgs1799 Yes, definitely changes happen to the viscosity when the temperature changes. So if your oil source is in a building that warms up as you use the heater you need to be aware that it will dump more oil in as the temperature rises increasing the flame even to possible danger levels. (As shown in our "top 10 dangers" video) But if your setup is outside, as in the video, the temperature remains relatively stable as your building warms up, so no problem.

@superochoo, Thanks for the comment. Sorry, no diagrams or drawings just step by step video and descriptions. Remember a video is worth a billion drawings. But if you have any specific questions we'll try and help. 🙂 Happy building.

Hey Ss, thanks for the comment, Yeah, I do not like clickbait either, but if you read the thumbnail carefully it does not say no fan or blower...it specifically says "Can run without any electricity" and "no blower required" which are both true. the video is supposed to show people that these things are not required IF you have a chimney with a strong draft which will create enough pull to run a great furnace. But that you can also run this same furnace without a chimney and use a blower, it just demonstrates the versatility of such a bottom feed burner, blower and no chimney - blower and a chimney to remove all toxins - or no blower and a chimney. If you watch carefully, right after the discussion of not using a blower there is a shot of the blower hose removed and lying on the floor at the 7:56 time mark. So it is all there if you watch the whole video and pick up on all the wording used and its intended purpose of helping people make decisions before embarking on an entire build that they may not be happy with later. But I can see where that could be construed as something mischievous, especially understanding how some people run their channel through deception. We at Learn2farmagain have no such intent (Leviticus 19:18; Matthew 5:43-44) and only wish to share so others can make an informed decision and then help the entire RUclips community in sharing and rocket fueling our production models to the perfect furnace, especially for those in need of cheap energy to heat food, water, or buildings to live happy lives as they provide for their families.

Hey user-vx2in8uc7s thanks for the comment. yes, videos can take time.... not everyone appreciates that until they do it themselves, so thanks and happy building...

Hey bygeorge328 thanks for the excellent comment. Yes, it has been a long time in progress but thankfully it is working better than planned or expected. Now that we have a working model all the following ones should be much faster to build. Be sure and share whatever you come up with to add to this one, like water jackets, etc. There are so many possibilities on various ways to build these and ways to deliver the heat into a building that I can hardly wait to see a year from now what it all looks like. We are working on one now that will have a heat exchanger on the bottom, then a small water jacket for showers etc., a small steam generator to a turbine system for led lights, and then of course a cooktop on top... Happy building. 🙂

Hey jrgmty7685 thanks for the great comment.@7685@7685@7685 Yes the conversion from heat to electricity through steam production is already happening all around... Usually people skip the steam engine and just use a pot of water with a small hole to let the steam under pressure spin a turbine mechanism to generate small amounts of electricity for lights etc., With a lot more work you could build a steam engine to generate more power though. Great thoughts...

@@learn2farmagain30 that's cool. 😎

Hey psyamok3735 thanks for the comment, great question, it is just a part of a plastic blue 55-gallon barrel. Usually easy to find and usually less than 10 dollars each. (many uses). In fact that is what is at the other end of the big pipe, another 55-gallon blue barrel.

@@learn2farmagain30 I mean the blue part where you have the water piped into, at the toilet seat.

Hey @psyamok3735 ok that part...sorry... That is a special part called a separett you can get it on Amazon. Here is the link... www.amazon.com/Separett-Privy-Kit-folding-seat/dp/B01N3YYG9Q/ref=mp_s_a_1_14?crid=3385NR6YMAGA4&dib=eyJ2IjoiMSJ9.Xe8onop-u48Cw_LxcejkIIk27NL4O506A2wBk4ViIuNFdrXfb9iEEg-qugI0rxxR0gVLAY1QID_IwT2sRf2E5nPl3PQWnwSbnkhw7YIN56Wox8Jzw3k8yV1HZooI-OEXx9j-JLh7z2vK0zfN2mtCTrwUcUJ9kPBidsk33MJGGm85pUmHGOsYTeyeMvjIp32Y2LTgG_edcbMCU-QkzrHF5g.PRs5aQqWEEAtJa0KtNHcCOXV9hp7DgP8yXzmiVFts4Y&dib_tag=se&keywords=separett+toilet&qid=1710301251&sprefix=seperett+toi%2Caps%2C253&sr=8-14 Or a cheaper one: www.amazon.com/gp/aw/d/B0BNTSR7R2/ref=ox_sc_act_image_1?smid=A126SCFIZOG0TY&psc=1 Hope that helps...

hey hjhenk422, thanks for the comment. glad you like it....does this mean you are currently starting to build one for yourself?

@@learn2farmagain30 yes im coverting a woodstove to waste oil atm , and i love this vid you made very usefull

Hey jkuneck thanks for the comment. I hope you have a great time building your furnace!

Hey BradShows thanks for the comment, Yes, I love that ending too. I've actually watched some of your videos on your channel before, I really like the quick skit idea, you also have most excellent content, dare I say that it is even better than this channel! This stuff will keep you warm, but your channel has more eternal value that will last well beyond the life of a waste oil furnace. 😊😊

Hey jrgmty7685 thanks for the comment, that is a great idea. I would probably use a blower and solar power as in our camping stove video first so I would not have to pump the whole time, but it would certainly work if someone else was pumping while you cook. so many great ideas....thanks.

@@learn2farmagain30 the only problem with solar is the sun is not always there. But still it's good to keep all the alternatives 👍🏽

Hey eshetchayil4669, thanks for the most excellent comment. Yes, part of the whole purpose of the video is to help us all to be able to have heat, hot cooked meals and hot water production at zero to no cost. Looking forward to your build video soon! 😊😊

Hey @Blxz, Thanks for the comment, Yes, I agree, there are so many good videos to watch out there. I hope you build an awesome blue flame furnace yourself soon...and share!😊

They are awesome!

Yep! Somebody knows their sheep!

Hey @chryslerjune, thanks for the comment. Stay tuned because we've got a better one coming in the next week or so. There are many clean burning heaters/furnaces out there now you just have to search blue flame and they are usually pretty good, the yellow smoking ones are just too inefficient and dirty/smoky anymore. They can produce a lot of heat though. Happy building.

Hey @hitekredneck109, Thanks for the comment. You may want to wait for the next video, we just finished a superior model complete with heat exchanger installed in a home. Final test was actually today (2/8/24). I've seen nothing like it online to date, we will begin compiling the video now, hopefully it will be published soon. Happy building.

@hitekredneck109 that video is ready if your interested...here is the link...ruclips.net/video/xdsrziVsI50/видео.html

@@learn2farmagain30 thanks!! I'll check er out 🤙

Hey coachgeo, Thanks for the comments, great observations. If I'm understanding your questions correctly, on the oil backflow, if you are using blueflame top flow like in the videos then you would have to fill the furnace with 1 1/2 to 2 gallons of oil before it would come over and out the burner air pipe. Also because of the design used on this channel, the burner over a pipe setup means flame out before spillover so no dangerous oil fire, just an oily mess that should never happen if you have less oil in your feed than your spillover level, and if you just peek over at the temperature gauge every hour or so to notice any problems, you'll see the problem before any danger happens. These setups are simple easy to build and have free heat, they are not fully automated with electronics and leak detectors and shutoff solenoids, so they need to be cared for. There should never be an obstruction in a blue flame setup, there is no hard crust formed like in a yellow flame furnace, just be sure to screen your oil first. It is nice to have a setup that stops the flow of oil @ some point, but easier than that is to have an oil supply that is less than your overflow point. Hope that helps, if not just let us know...

Hey Penny, Thanks for the reply... In this demonstration we are simply showing a danger to all those who are designing a "safer" waste oil system to try and get air into a living space, not just a barn or garage etc. but an enclosed living space. While this is a noble or understandable endeavor, the danger is if you have a type of outdoor furnace setup to be "safer" and then blow the heated air in, even with a proper chimney, if anything in your experimental setup fails or leaks, it can blow carbon monoxide, foul gasses, etc. into your living space unnoticed - very dangerous. Of course you should never blow the chimney heat and gasses directly into your living space. This was just a demonstration to get people thinking. It's more difficult to show a perfect outdoor furnace with a tiny crack in a heat exchanger delivering invisible gasses into a home killing people. Hopefully this was enough to keep people thinking and from endangering themselves or their family while they are just trying to stay warm affordably.

Hey @DamonBrown-tm8hc, Excellent comment, we use a fine kitchen strainer as shown in the video starting at 13:12. Also, the barrel is an awesome idea for heat savings, although not as much is lost like on a wood burning stove which is usually around 400 degrees on the vent pipe to get a fireplace box about 500 degrees, whereas this set up produces between 700-900 degrees Fahrenheit (depending on the blower) on the furnace with only about 200-250 degrees on the vent (another awesome feature of these furnaces). So you could save some heat, but if for any reason your flame goes out, you risk making a giant bomb (if you use a 55 gallon drum) in your living space if it reignites. I highly recommend everyone watch the "waste oil burner top 10 dangers" video on this same channel before making a furnace of their own so you understand how to safely operate and what not to do with these furnaces. Happy building and play it safe...

@@learn2farmagain30 I missed the strainer the first viewing. I get it now. I watched the top 10 dangers ruclips.net/video/w97RFaMgUf4/видео.html and makes more sense to me. I also see when you have a flu pipe you add a cover to the top of the furnace but it's loose on top, in case of an explosion, it can just pop off. Love your videos!

@JonDingle, thanks for the comment, Yes, it sure would be nice if RUclips would provide a list of music or songs to choose from right before you watch a video that could be applied to that video, that way everyone could enjoy it more. Until then some will like the music provided in the video and some will not. To that I say, thank God for volume control... Happy furnace building, stay warm...🙂

Hey english, Thanks for the comment. And yes I have seen Dawlac Dojyo's work, he does a nice job on his furnaces, good ideas. As long as you can get a blue flame using something that is so often disposed of, it's all good. Can't wait to see your post when you finish yours...hopefully with a few updates to show us all.

Thank you also for scripture. Corinthians at the end.

Hey @reypolice5231, thanks for the comment. No problem, glad you liked it...it is quite the noisy process, but then it should serve you for many years to come. Happy building. 😊

Hey @arklaskanadventures, Great question. The fan just slides on the pipe shown at the 1:07 time mark. Most fans either fit inside or outside the 3/4" pipe used. We've found that the computer "squirrel cage" type lasts the longest-very efficient. Happy building.
