New Waste Oil Shop Heater Build! Ultra Efficient! DIY Project 

This is getting filed under "stuff to copy" 😆 Brilliant

funny how we wait until its freezing to build the heater LOL

It's a work of art 😊. Should fill bottom with sand to hold the heat.😊

Great first attempt. Two staggered rows of heat exchanger tubes spread across the width of the fire box would yield greater efficiency. Smaller, more numerous holes in the air feed side of the burn pot will help with a cleaner burn. Try a smaller throttle valve, maybe even a needle valve. Great reuse of old equipment.

Excellent craftsmanship! Very info for anyone looking to build one. You definitely know what you are doing.

Absolutely one of the most clear and comprehensive vids that I've watched I will be rewatching this often, as I consider it a textbook presentation! Thank you sir!

Thank you for taking your time to share. Nicely done video, no nonsense and straight to the point.

Awesome build. You have great fabrication skills. Thank you for sharing!

Been designing and building my own woodstoves since the 70's and I just might have to build one of these next. This burns as clean as my wood fuel designs. Well done. Subbed 👍😎👌🇺🇸

very very nice build. Thanks for taking the time to show us what you built.

Functional and cool looking, perfect garage heater!

I enjoyed the build ,great job. I really like how you repurposed steel and worked to get the best yield of your materials. Cheers

Man, you did a fantastic job! I've been consuming every video I can find on waste oil heaters, and yours is by far my favorite. I will say that you would probably benefit from some burn chamber mods, but overall the rest of the build is incredible. Thanks for taking the time to film and share with the world.

Great build. 👍 you have spent a lot of time researching for your first build! I have made many oil stoves and all different designs. If you put a flame deflector around the burner you can keep an even burn at low flow. But please don't walk away from the stove the oil flow will change with temperatures increase its a drastic change ! The only way to keep the delivery the same is to keep the oil tank the same temp. Be careful! Awesome job! 👌

Super cool build, will have to make my own. Thanks Jay.

Looks great. By the heat waves coming off the chimney, you might be able to capture more heat off the stove pipe with some fins.

Good morning and thank you rusty. The most complete video I've seen On this. I have been going to build one just like what you did. Force there for my garage, But I need to add a hot water loop in the heat exchange your tubes to go into my house heating system at the same time. Again thank you for the Is step-by-step.

Very well done on your build, video and quality of work. On the one I made I used 15 feet of stainless steel pipe that feeds my base boards the hot water. With mine I soak a sock or small rag with kerosene to start the fire, that way I only open the door once to light it to reduce smoke intake.

Nice craftsmanship and presentation. Your a pretty smart guy. God bless

You made a nice heater out of scrap Well done Sir and nice of you to mention GerrysDiy

Man I love that old Firebird sitting there!!!

This is BY FAR the best one I've seen on RU-vid. Great job man. I been looking at a bunch of videos to get idea's and i think i have it figured out now, because of your design.

This came out awesome! Well done man! On the burner and the video!

Nice job on the unit. If you put some oil in first and the kerosene on top, you shouldn't have any problem lighting it. Mine starts in a split second, with only a whiff of the torch. I use diesel. Also, if you hold off on starting the blower till it gets going, that will help too.

Yes. I enjoyed your video very much! It was also very helpful for people like me that want to build something different that works better than anyone could expect!! Well done sir💪🏼 Happy Holidays to you and your family

Man, that turned out slick! 👌

Very nice build. Really appreciate the video and taking the time to make it. Thanks for sharing with us.👍

Awesome build. You need to update us on how it has held up and make more videos! Excellent content!

Great heater man. Thanks for sharing

Excellent job!!

Great video and build. Love the glass door.

Nice job, it even looks good!

Awesome setup!

Fantastic! If you set an old brake rotor or steel plate on top of the burner pot it will increase the temperature, which will increase the burn efficiency.

Rusty, nice and clean waste oil heater !

Very nice work 👍 thx for sharing

Great job J

Man with you build . You bring it one step closer to being able to have a oil burner heater design. That would not look bad inside a house. I think ideally if as builders. We could make something way better then a pellet stove and way quieter

Great job,I really enjoyed the well presented video. It might be interesting to see if you could add a wet heat exchanger and a pump a small expansion tank and run a couple of radiators off the system.

1st, get a small fixed displacement oil pump and set it up on a timer to regulate the oil flow. Then you don't have to fiddle with the flow rate with different oil weights and Temps. 2nd thing, put a flame sensor switch hooked up to a valve to shut off oil in case of flame out. The other thing I have been toying with is superheated intake air to allow for cleaner combustion at lower flame.

Great video. Thanks for your time

Nice Job, ..... Bravo !

Nice build, well presented and edited!

great put together video

Nice looking frirebird

This is beyond my expertise, very impressive skills man

First class and very informative. Merry Christmas from Scotland

Excellent build I'd move the resovoir much further away for safety nicely done

Awesome! Thanks for sharing

Awesome build there. I need to build one a lot smaller.

Really great build, and you explain your work well. Read a bunch of the comments and no one seems to have mentioned your oil tank. Just a guess, but you may want to move it outside of the room, because as it warms up, the oil will get thinner, and flow more freely. This vid is 2 years old so you may have already dealt with this, but I wanted to mention it. I have an old oil tank I've been giving dirty looks to for awhile, and this is very motivational, thanks!

Great build!!!

You might want to try adding some fire bricks to the bottom of the burner pot. My high school shop teacher built one that way 40 years ago and it made it much easier to light. Overall it looks like it's going to keep you warm! Thank you for the detailed build.🙂 Hmmm make that 43yrs ago! Me old fart yankee

Nice build

Great job Im impressed

That is so awesome

That’s pretty sweet !!!

Rock on, clean build

It's amazing how a tiny stream of oil can produce so much heat. In essence, oil is concentrated sunlight.

Well done

Looks great

Very nice build!

Nice build buddy! I like it. I'm sure you'll find some upgrades in the future.

Nice work

Great work!! Might I suggest that you replace those gate valves with globe valves? They're ideal for fluid throttling and regulates better.

really great work

Pretty neat

Great build bud!

Good job really nice like it

awesome build!!! .... now if you'll excuse me, I've got to go look for an oil tank!

Nice job

You just got a new subscriber. Great work

Great build, I have been working on and building cremation equipment and boilers for 25+ years. The only thing I would have done differently is used some 304 stainless to make the burner pot.

You could scavenge a bit more heat from the top 1/3 heat exchange area by adding some plate at angle to force the rise directly between the tubes (from the wall slightly upward to force air path right through the exchange tubes). then a roof plate above the tubes like a slight angle being higher at the tubes and lower at the wall leaving a .5 to .75 inch gap at the wall for the exiting air.. this gives more time and direct contact on the heat exchanger tubes using thermal stratification to your advantage. That should get more energy into the shop and less up the flue. If it becomes a permanent unit you could do a baffle box around the blower side to pick up air from floor and reduce the noise a bit although it was rather quiet for the blowers size. This box could be simple double sheet metal ducting material with fiberglass insulation between and 1-2 plate of baffle. You could even filter the air if you want pulling in air from the corner of wall to reduce noise and keep squirrel cage blades from clogging over time. Other things to consider or try is adding carbon felt (welding blanket) material to the burn pot as a wick. This will make the burn more even around pot and drastically help with start up. You would have only needed to hit that kero 1 time with torch with a carbon wick in that pot. That material generally comes in 1/4inch thickness so a single length stood on end inside the burn pot should work miracle for you. That may require a double ring stand to hold it upright could be simple as stainless mesh or as complex as you like but plenty of air holes where the stand contacts the wick material would be best. This all could allow or call for a multi feed point or a feed lip/mote in the bowl. But that carbon felt material will hold up to tons of heat nothing to worry about there. this could als be as simple as a ring of 1/4-/1/2 inch pipe hooped welded closed and a 1/4 inch slot atop the pipe to insert the carbon felt. I think one of these mods would get you somewhere closer to where yor intake air control would actually be useful rather than wide open and burning mostly on one side of the pot. The air feed/pickup preheat stack pipe could have been modded to pick air to the top internally then blow downward at the drill locations which could have angles reamed/ground top and bottom of holes (top of hole ground on inside and bottom on outside) this would have gave a downward force to the drilled holes pushing fresh high temp combustion air deep into the pot rather than directly outward from the holes. Intake air has to be preheated more like wood stove catalytic secondary air must be preheated this whole section of waste oil burners is overlooked in most builds. In a great build you should see the air intakes at the top of the box to collect heat then down and under the floor plate and back up through the air blast tube section which would be doubled so air goes up a smaller pipe hit a bell shape then downward in the double wall section and out the drilled orifices. For that you may had needed to go down half size of the original hole then ream, angle or even bend those drilled holes to the desired shape... This would give 2 effects on the air entrance to pot angle effect 1 (reamed holes) is the sharper and thinner points of the holes would give up heat to the air passing through a bit better a bit more surface area there also angled versus straight holes. Thx for the video it is a nice unit dont take my input as criticisms the unit is nice as it is.

Awesome build, I think I want to try that... I just have a little drip over my wood to make the wood last longer. But, your build is next level.

Awesome video

Good job! Now some paint and a cleaned up sight glass

Good job

Solid build bro

nice build

In addition to the comment I made re sight glass, I wanted to say I would love to make a smaller version for my 380sq' garage vs your 600sq' shop. Unfortunately, my city is EXTREMELY intrusive and controlling. (We should rename it "Stepford" lol) I'd have to do it "under the radar." :/ Fantastic project! Now I just have to learn how to weld!!!

For greater efficiency, move more air through the heat exchanger: more tubes (more surface area for heat exchange), more air velocity. The cooler the air is coming out, the more heat you extract. Obviously you want air coming out to be warm enough to feel warm, but a small amount of air heated to screaming hot is nowhere near as useful as a big amount of air that is just a couple of degrees above your desired temperature.

Looks like a Lopi wood stove front door, nice. Increase the height of the combustion chamber and inject some air into the flame higher up, high enough where it won't blow out the fire. Injecting air into the yellow flame can make it burn blue which is more efficient and cleaner. Angling the air injection points to cause a swirl helps too. The problem with these kinds of stoves is that oil flow can vary. If there is a bit of sludge in the oil the valve must be opened more. When the room heats up and the sludge clears the metering valve the oil flow goes up which could be a problem if no one is monitoring the fire. As a precaution the oil supply container could be limited to an amount that could not overflow the combustion chamber.

Thanks for posting this! i was looking into making one for my 1 car garage to burn all my used motor and cooking oil. Just based off the size of your tank, i think i would need about 2 quarts of oil an hour for the size of my man shed. Not sustainable unless i offer to change my friends and family's oil for the fuel lol.

Damn bro you pretty much reinvented the wheel here!! Very elaborate build that wasn't necessary but a very nice buil at that.

that pontiac is cool,

There's a few easy things you could do to optimize the overall package, but man that thing is cherry! Me being me, I'd find some kind of way to extract your flue heat to turn a generator and have it power itself (and maybe your shop), but that'd burn a bit more oil undoubtedly. Nature of the beast. However if you've stockpiled your gallons, it'd be really sweet to see this thing be self-sufficient!

Get an old 2x4. Put it in the chop saw. 1/2 wide cuts. Soak in bucket of kerosene overnight. Perfect fire starter!

Great build. You could probably easily double the efficiency if you set up a unit to store some heat. If set up a small drum sealed with oil and exchange some of the heat into the drum ...That drum of oil would stay hot for hours after the boiler is shut off.

I love the workmanship, i want to build somethhing similar from 2 barrels and some stove bricks so it also keeps the heat longer but, i think because you crammed those heat exchanger pipes so close together the smoke goes around them instead of through them... maybe a different geometry would have helped

A few windings copper pipe around itself, or the stovepipe , connected to a small tank, and you got yourself a hot water supply for free too. Great video anyway ;)

Great build I'm impressed! Some years ago I built a burner for melting alu and brass. I use a mix of 50 % of diesel and waste oil. It also needs compressed air to work and a fan for better and cleaner burning. I have som videos of it on my channel. Oh and by the way I subbed to your channel, I think you deserve it. 🙂

Nice build! I would imagine the viscosity of the oil might change as the temperature increases. What would happen if you lose electrical power? The reason why I asked this is I know of a man who had a stove in his basement with a fan that circulated the heat. He left for a few days on a business trip only to come home and find only the chimney standing. I know you can purchase these prefab with 100% clean burn using just about every kind of fuel out there however, they are in the thousands and thousands of dollars. Thanks for sending me the link!

Very nice job ! I really like your build ! Just wish my body would let me build one ☹️

You should consider installing a barometric damper on the flue to help control the immense draft generated by the long length of pipe. This will help keep more heat in the stove and not suck it out of combustion chamber at hypersonic speeds. Looks like a lot of heat wasted coming out of the chimney.

Hope Santa bring you a grinder for Christmas!

Now all I need to learn is how to weld! 😁

looking forward to new vids, Alex.

Also, make a lever on the dial so you can adjust finer. Thinking that will help. Though amazes me how much heat is wasted out the chimney. Thinking even energy wasted using the blowers.
