Chinese diesel heater ran on used waste oil clean out 

Tip for u all, if you run the exhaust into a 55 gallon steel drum and then out the house from said drum you get twice the heat..just saying.

You guys are fun to watch, thanks for the chuckle.

Very useful info... Good to see people keeping things running by taking them apart and cleaning everything out Keep up the good work!!!! More please!!!!!

Hell yes. This exactly what I was looking for and stumbled on the video by accident. Thanks for the information bud!

I tried this with mine a year ago with the same results. Maybe I should have made a video of it and saved you the time, lol . Good vid.

The word that you are looking for is " clinker " the hard remnant of burned coal . Good video, going to try using motor oil cut with diesel in mine .

The cinder-rock stuff I believe is called clinker, another great video buddy thanks

Beautiful home install. Looks amazing!

For anyone wanting to run used motor oil just beware that this is what you'll expect real quick, so if your heater is important just keep running diesel or you'll be without heat at a bad time. I made a diy waste oil heater for my garage a few years ago and even with the burn pot getting red hot that rock like clinker stuff still showed up, and the ash accumulation was incredible, as if i was burning liquid wood. it had to be cleaned and emptied every 4-8 hours of use . It was such a pain in the ass i got rid of it. Just a fair warning to keep people out of trouble as there's lots of interest in free fuel alternatives.

10:20 The word you're looking for is clinker. Main reason for coking up (imo) is running at lower temps, not the fuel. Always best to burn at max every now & again. Great vid, thanks for posting!

Haha, that was so amusing! I have one of these under my camper and someone parked the diesel supply pipe on top of a tree trunk, flattening it. Turned on the heater and of course it started smoking. Plenty of white smoke! Looks like we'll have to open it up like you showed here and clean out the soot. Thanks guys, very amusing too

Very interesting. I am making plans to run a plastic gasifier, which gives you a nice sulphur-free diesel and kerosene mix out of the end. Looks like I could burn that nicely.

that ultra sonic cleaner like sound from 3:50 killed my ears, thanks

Great test,torture and tear down !!

Yay i can see the inside without taking mine apart

Great video thanks for your great info .deisel is so expensive now here in New Zealand I am going to run mine on other stuff cheers from Keith 😉🙃

That little mesh screen cylinder is the atomizer screen. For starting, clean that one more often than not as lights the oil as it comes into contact with the glowplug and heats the next chamber where the real heat comes from

Great idea guys, you've got me thinking how to modify the cat flap 🥾

Very useful! Good heavens your tool bag is utter chaos.

I used to clean my ganja pipe in a similar way with a blow torch🤣❤️

People love these things dont they 😅 , they are awesome little beasts 👍👍

Great video guys thank you

That plate heat exchanger (14mins in or so) reminds me of the one I took out of my old Vauxhall Omega (3.2 V6, sitting in the middle of the vee) when it failed and filled the coolant system with oil.. I could have used the ultrasonic bath to get all the milkshake out of the header tank! :)

Same problem here running it months on end just red diesel tho. I used a propane torch, a compressor with air chuck. Get the soot to burn then feed it air!

The key is to mix the waste oil/diesel/gasoline at roughly 50:40:10 - i just guess as i mix it all in a 5 gallon can. I will run like 25-30 gal of this then a gallon of diesel on high to get it real hot. Ive kept this pattern for like 3 yrs. The hot run of diesel is basically a self cleanse and i get a lot sparks and soot out the pipe

21:10 The N/S "polarity" of the magnets stuck into fan is important. The Hall Effect sensor only detects one side of the magnet.

Great work review

Maintenance to keep the soot down on these you run them at the highest setting for 30 minutes or more to help Cook out the soot

Thanks for this thorough test; That's amazing that it's happily run on anything flammable, I'm increasingly more interested in getting one of these for the workshop now, given I can get loads of used veg oil and motor oil. Just thinking about the AFR on it; it's a shame there's not a sightglass into the burn chamber so you can set it for a nice blue flame (like those old Gunsons colortune things for petrol engines)

Just got a Vevero and tried it out I’m very impressed Got it to heat out green house in Alaska so we can get our vegetables going because of the lack of heat and light

I'd call that experiment a success.

Recently cleaned out my diesel heater after an e.10 error. A can of carb cleaner and a pick scrapping the crap out of the carbon and it starts up SO easy.

that looked way better than mine than ran 5 months 24/7 on diesel

If you run a secondary tank with only kerosenel and some conditioner that boosts cetane and start it on straight diesel, then switch over to your oil mix and when you shut down switch back to kerosene and run it hot before you shut it down it will stay cleaner longer

I heat my whole house with one of these, only have to light the wood stove when it gets below -10c as it cannot keep up below that. There is significant heat loss out the exhaust on these, I vent mine into a masonry chimney and it gets quite warm after running on high for several hours.

Fuel with water is probably what was helping keep it clean!

Thanks. I wanted to know if this would work with other fules and you guys have tried it years ago. This could be usefull for a lot of people just now

Years ago I decided to fit a highly recommended item to all our cars as we were knocking up the mileage, fuel economy , clean burning , good fuel economy etc was a priority .as we were doing almost 1100 miles a week between us . So I put a Slick friction reducer in all three engines at the recommended rate and added a bit of kit that worked out at about £46 some 35 years ago The bit of kit was a catalyst cartridge, dropped in the fuel tanks at the sender units secured for easy removal on the sender unit with a very thin knitted nylon cord ..... I fitted them to my diesel BX19 TGD, my wife' petrol BX17 RD & my daughters BX leader..... it was made by a company called Broquet . I had cause to take the head off the RD which my wife had had for five or more years because it had a tiny water leak in a rad hose and my wife ignored the warning light as she was only 60 miles away from home , it over heated , warping the head , the speedo showed it had been round the clock at least once . On taking the head off I was surprised to see everything in the cylinders, on the piston heads and on the actual underside of the head & valves heads was as clean as the day it came out the factory , the exhaust manifold was exceedingly clean as well . So as a result of that experience I wonder if putting a Broquet cartridge in the oil tank would help as it is supposed to align the fuel molecules better ( It is a British invention developed in WW2 development to allow Spitfires to run on rubbish Russian petrol ).

not much structure, but many words at this interesting project.fine, thanks.

Those hard chunks you got out us farriers call them Klinkers we get them in our coal forges but they are massive in comparison

Add some eliminox to your fuel it will sort out the water contamination, you'll get a cleaner more efficient burn and better fuel economy, less emissions, it's amazing

I've got a Finnsonic ultrasonic cleaner from the side of the road. It seems a bit impotent. It does blow holes in tin foil, bur generally seems a bit tame.

Hell just run automotive desiel with filter and blast it hard every now and again ay

Great vid

A great informative video, i wouldn't use electical conduit as not airtight.. i was wondering why no one puts the exhaust into a 2 or 3 inch verticle flue! it will slow the gases down, and transfer to the larger exhaust pipe which will radiate heat into the room, but would keep it verticle...

The reason it runs so clean is because of the high water content. Hydraulic oil absorbs water and water is great to de-carbonize hot carbon off of things. Spray water into a hot engine to clean carbon off of valves and stuff.

separate oil from water. filter oil. then burn. to clean unit burn transmission fluid. or a mix.

Before we built I was running a 900W 2 stroke generator and the muffler became clogged and I tried burning out the soot build up with no luck so now I thinking of convert it to steam

I ran mine for two days on black diesel 70% oil and 30% gasoline. I had to clean it out because it looked just like yours.

What are you using for cleaning solution in your ultrasonic?

I will see how you do it and learn.

What brand is your ultrasonic bath? I have been thinking of getting one but want to choose one that works and there is lots of crap out there.

Have you tried running on straight waste vegetable oil? Do you have to heat or mix it with other fuel?

I think I would try Berryman-B12 in my diesel to help keep it clean ?. Just a thought.

A review in the rain 🥶 aaah

For the interest of people who like me to experiment I coked one up (my first one) it wasn't hard to work on but my mind thought of the heater plug and controller problem and only took it apart to clean (with ordinary oven cleaner) to cover all bases I thought the thing I missed after connecting rubber pipe to the to the inlet point it was also blocked a quick scrape with a bent paper clip it cracked straight up, summary: I bought bits I didn't need but great for back up, you can clean with oven cleaner, (some may have a better idea but so what there cheap) I probably could have got it going with a bent paperclip but i got some spares and about to enter year two of heating the house only from the heater nothing else

The wicking inside gets dirty and then it won't start. You need to take it apart and spray it with carberator cleaner and blow out the crap with high pressure air.

The black hard bits is calked Coke. Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air - a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern. Wikipedia :)

You have to start them on diesel or kerosene and end them on diesel or kerosene . Otherwise you will get buildup. Preheat the dirty oil a little too off the exhaust gases and you will get a better burn. You would have to make a copper preheat coil or something. Don't overheat the oil though..but the exhaust don't make a lot of heat. Just gotta keep enough below flash point at all fuel flow settings.

Honestly the best way to clean this out initially and for the final scrub is Mr. Muscle foam oven cleaner. The amount of engines, intakes and exhaust headers I've cleaned in my time with that stuff is unreal. It just anhiliates any carbon build up from anything.

did you try to use a Arduino to control the burner yet?

My heating boiler didn’t like dexron typed hydraulic oil and coked up much the same on the flame vortex generator! On normal clean used engine oil it is absolutely fine with no smoke or aroma. Mine is diluted significantly in the 250 gal oil tank obviously. Shame to waste good hydrocarbons.

Any tips on how to clean filter used engine oil please

I think Ide stay away from vegetable oil as it polymerizes to a rock hard plastic like gunk when not completely burned. that's why they presses it to remove the polymers it to run in a diesel engine

You need to reduce the Hz and add fan speed to get the proper air to fuel raaatio and that soot will be greatly reduced.

Sorry, #1 Diesel and Kerosene are two different fuels. In Canada, when these heaters start to foul, usually by running on #1&2 Diesel, the repair stations run them on clean straight Kerosene for 6 hours or so, if that doesn't cure it, they do a tear down and clean out , similar to the way you did. Best wishes from the far North.

Run the fuel line through the exhaust or the heat exchanger to preheat the oil to at least 160f but don't go to hot or carbon will form with some solvents in the fuel line. this will cut down on the build up and will help with restarts after the initial startup. burn chamber need to get above 650F to stay clean fyi. Ps if there is any residual oil b4 650f it will start vaporizing and you may have a bomb on your hands. Don't ask me how I know.

I have been Running used Veg oil in Vehicles for a LONG time. One of the things I am adamant about is running a very basic water injection system in order to prevent and clean out any deposits. It works exceptionaly well and you will always have a perfectly clean engine if you dose it regularly with water. Normally this is sprayed into the air intake as water in fuel is not good for injector pumps and injectors. I'm wondering if your watery Fuel actually helped keep your Burner cleaner than it may have been otherwise? I can think of for and against reasons But No idea which might be reality. I am thinking that perhaps some water in the intake might help here. I believe it would have a different action to water being in the fuel. It would only need a very small but constant amount, maybe something like a low pressure stream from something like a hypodermic needle. It would work it's way into the combustion chamber from there. Nothing fancy required. I am seriously thinking of one of these to heat my house this winter. The seem to be more economical that electric heating for the power out put. If I could run one on 75% WVO, that would be real economical. If the water feed kept them clean, should work till the thing wore out and Like a diesel Vehicle, would made sure they started easily as well. For an engine I implore people to dry their oil but in this case, I'm leaning more to the wet oil being a good rather than bad thing. It will cause a bit less heat output but probably a very worth while trade off if it helps keep the thing running on Sump Gunk or whatever you feed it.

Can damage bearing when fan is not running when cleaning with heat like that

Hi John, thanks for taking the time to make the video. What's your thoughts on running a 50/50 diesel/waste engine oil mix?

A soak in strong caustic soda solution removes burnt on organic crap without affecting the metal (unless it's aluminium which won't be the case here).

@JohnDragonMan I was interested in seeing just how far you have run the output heat duct. How many metres is it? does it still get hot at the far end?

I checked the exhaust temp when new. The checked it after a year use. This will tell how much soot is built up. The more soot the less heat on hot air discharge. The more soot the higher the exhaust temp. I only run clean diesel. I was told I could run home heating oil. But have not tried yet.

Now I know why my 1995 7.3 powerstroke loves hydraulic oil as fuel over new engine oil i get for free from cross grad contaminated by pump flushing. Heres my special fuel mix 80%-70% hydraulic 15%-20% diesel and 5% up to 10% max gasoline preferably old gas, use as thinner/ filler because oil will give you more btu,s which really helps spooling turbo, but best used undergrad on highway low rims. Just some ideas for you guys.

Feed the exhaust through an old radiator if you have enough ventilation for even more heat retention 🤒

The most likely point of failure on these will be the fan and the fuel pump (maybe not in that order). But there is no reason that they cannot be run for thirty years before the design actually fails.

I have a feeling, if the oil was properly refined it would be significantly less of a problem. Considering vegetable oil has a similar issue in engines that goes away when it's properly refined.

If something sounds to good to be true then it probably is. Used oil will test your patience, guck everything up, endlessly cleaning. Also, no such thing as free fuel, no such thing as clean burning oil. I’ve run these things for years as a diesel engine heater, run it all night to keep our trucks warm. Very popular in northern Canada, it’s called a pre heater, runs off your diesel tank, big deal.

Would you use straight filtered used motor oil or would you add 50% diesel, let's say as an example mixed with old oil? Also, I'm wondering how transmission fluid would work? Were they harder to start initially?

How long will it run on used engine oil before needing a clean out?

Awesome thanks for sharing. are you Derbyshire lads by chance?

I used the hand held propane to burn out my deisel heater like you did and completely melted the center cone out of it. People DO NOT use the flame method in side of these things.

Hi John, great video I was just wondering what are best advanced settings on the controller As I am using old engine oil and kerosene 50/50 and I've had oil coming out of the the breather pipe so I had to strip it all down and clean it all out.

Can you point me in the direction of the metal conduit you use to extend the exhaust ? Just looking to do similar. Thanks.

Filter it before use... The oil will burn cleaner... Your Pal BigBadBubbaBurns

if you don't mind saying, what settings do you have for the used oil?

Oven cleaner works to clean it out.

Just curious, has anyone tried putting commercial additives such as redex in the fuel mixture to see if it helps decarbon the unit? You can buy one that is designed to clean the dpf on cars by burning hotter quicker. I've just started looking at these heaters as a potential boost to the household heating system, sorry if I'm asking obvious newb questions. Great vids btw.

Thick oil especially vegetable will burn like kero if you warm it. A copper coil wrapped around the exhaust will do it.

waste motor oil should be passed through a centrifuge, then filtered 2 or 4 micron and then blended with diesel. Engine oil filters are 30 or 40 micron and by the time it gets changed, its loaded with soot. People making black diesel also know that synthetic engine oil is more difficult to burn, and needs a higher ratio blend with diesel or gasoline. Stick to process used to make "black diesel" and results should be better.

I tried a 50/50 mix used engine oil big fail error 08. Any help please

What model is this thanks

Do you do anymore diesel heater fuel working testing? I would be interested to know if lamp oil can be used as diesel heater fuel?

Burn anything, but don't use motor oil, It is full of solids that do not burn its guaranteed to cause problems. Stick to used automatic transmission and hydraulic fluid. mineral oil probably good too, perhaps add a bit of gasoline to thin it out and assist in the combustion. Clean motor oil in itself has additives that will precipitate in a combustion chamber. Great video though. Pushing the limits of what these things can use.

It looks like an ultrasonic cleaner with aluminum safe detergent would clean this up quite nicely and easily

I'm all for cleaning stuff but it's cheap as they are just buy another one but still keep the one you got

Probs a bit late but might be worth wearing hearing protection near that ultrasonic cleaner

Alex has a channel 😮 I didn't even know 😅

Hello good video do you run yours on waste oil or a mix thanks

Is there a link to this heater
