thanks again for your experimenting..... now need to do same experiments but alter pump and fan speeds to attempt to approve combustion as measured by reduced smoke. This makes since cause this unit is designed with combustion characteristics of diesel.... so adjustments are needed when using something with a different combustion characteristic
I once mixed a gallon of diesel with around 300ml of crisp and dry veg oil and when i ran it through the heater it left like a varnish in the burn chamber. Like a hard sticky shiny film allover everything..
I see two problems, here. First, wait for the heater to get up to full operating temperature before switching to veg-oil. Second, "straight veg-oil" is likely too thick (viscosity) to be adequately atomized in the burn chamber. This viscocity issue could be addressed by either using a blend (mix the oil with diesel or kerosine - maybe 50%), or (if the pump and fuel lines can handle such temperatures) pre-heat the "straight veg-oil" to at around 150 degrees F (it's thinner when it's hot). Both these methods work in my 20yr old Ford Powerstroke 7.3 liter turbo-diesel, using waste-cooking oil. I bought it with 315,000 miles on it, and have used waste-cooking-oil for about 30,000 additional miles. With a total of 345,000 miles on it, she's still "strong as an ox".
Burning in an engine and burning in a heater isn't achieved with the same method. In your engine your high pressure pump and injectors atomise the fuel really well and it burns. In the heater we use some of the heat to atomise the fuel and burn the vapours. Vegoil doesn't do this well. As you've pointed out it's thicker so needs to be hot to be thin enough. Second problem is that when it atomises it leaves behind the triglycerides which end up as the black sludge that blocks everything. Thining with diesel and petrol while improving the burn only delays the buildup.
@@DavidMcLuckie As a former "Gas Turbine Systems Technician" (U.S. Navy's "Advanced Technical Field"), I do have at least some understanding of the benefits of compression, etc. I'm still curious as to whether you've tried waiting for the burn chamber to get up to full operating temperature prior to switching to pre-heated veg-oil or a veg/diesel blend. This could help to reduce the ability of stuff sticking inside the burn chamber. I'm also curious about how much you've heated the veg-oil (temperature range). Switching back to diesel/or perhaps kerosene (5 minutes) prior to shutdown should not only help to flush/burn out the veg-oil remnants, but also prepare it to start-up on diesel the next time it's put into operation. Also, have you done anything with bio-diesel in these heaters? I think this could be very helpful to people who may experience temporary limited access to fossil fuels. In my country, greedy politicians will continue to accept payments from greedy corporations, with no concern for whether or not people freeze to death, like in Texas.
It should help to preheat the fuel/vegetable oil. Try it on a Webasto Thermo 230, 300, 350 or Webasto DBW 2010, 2016, 2020 or th enewer series Webasto DBW 160, 230, 300, 350 as all these have a proper high pressure fuel pump and atomizing nozzle for the fuel. These use a spark gap to ignite the fuel, some are fitted with a glow plug to preheat the fuel to better handle B5, B20 etc. If you start it up on diesel and loop the return on the fuel pump around the exhaust or some other thing to heat the fuel I am pretty sure it would run straight vegetable oil with proper heat up first on regular diesel.
Another commenter confirmed they will run on veg oil, but it needs to be hot. Those looks like nice heaters, but I don't have the £1000+ to spend on one. :)
@@DavidMcLuckie Nice to know, I wasn't 100% sure and I haven't had the mean to test it myself yet. I bought all mine used, They pop up every now and then for cheap. Some need a need controller, some just a new fuse and maybe a clean out. Now that you have made the diesel heater shower you know how to implement an arduino as the new controller. The code and wiring will be a little different as you now have a spark gap instead of a glow plug and a constant fuel pump instead of a dosing pump, but the basics will be the same so not that hard to adapt. You also have a handy flame sensor available that tells you if you have ignited the fuel or not.
A pre heater for the veg oil might do the trick as it has a higher flash point than diesel at about 315 C whereas diesel is between 38 C and 95 C. Autoignition of various veg oils is between 406 C and 435 C and diesel is 177 C and 330 C depending on grade.
I did have a comment from a viewer who managed to get it to run on veg oil. The oil had to be over 100ºC as it entered the burn chamber. But it still leaves the sticky residue once it's burnt.
@@DavidMcLuckie The sticky residue is glycerin. Bio-diesel would work better cuz they remove the glycerin from the veg oil. That glycerin shit can harden like epoxy. Hence the reason why straight veg should not be used in diesel cars unless the vehicle is started on diesel, run on veg and stopped on diesel to clear the veg/glycerin.
Reducing the amount of oil being pumped in would prevent some of the problems. I dont know how for that unit but most controllers allow you to adjust the pump rate.
This would work IF you used filtered used veg oil (has a lower flash point than new oil) and adjusting the air/fuel ratio for more air (increase fan speed)
The only thing you can run on veg oil is a 300tdi or any early diesel motor, . For the amount the heaters use why would you run it on anything but diesel? Always enjoy your experiments with these . Cheers from Australia
Just out of curiosity how do u think it would handle moonshine??the idea being that there are no other fuel sources except what you can make or salvage.i think straight moonshine would burn way to hot but what if you mixed the moonshine with something else like the vege oil or waste engine oil???? Thanks
Interesting that a pre-heated unit kind of runs on veg oil but I reckon you'd have a bit more success with a diesel/veg oil mix. I'm not sure why people want to run it on veg oil as it's pretty expensive compared to red/kerosene which you can legally use for heating I think?
Yeah but kinda defeats the purpose, I was only interested in veg oil as a "green" alternative, if you have to mix, might as well save the effort and run it on the cheapest fuel you can
@@davidellis1355 Ah didn't realise it was for green purposes. Wouldn't a mix be more green than pure diesel and no reason not to use red/veg, that'd make it cheaper too, don't know what the ratio would need to be though.
Also, apart from not burning precious oil, if you can run it on VegOil you can often get it used from restaurants for free since they actually would have to pay to dispose of it.
Hellooooooo Davy boy, I can hear it now...Mee Maw, Mee Maw...i think the neighbours called the fire lads when they spotted the smoke. Interesting exercise and i got a good laugh out of it, and you didn't even have the chip pan on! Thanks for sharing. Stay safe and keep up the good work. 👍🖖😂
Hi, i bought this diesel heater on ebay, mount it but can not start(to many bubbles/tried 3 times) it with filter which was inside the box, when i dismantle filter it starts to run. My set up is tank, filter, pump and heater. It is mounted on the wall where heater is 1,5 m above the tank. I missed manual and mayby you know what is wrong ??
hi Dave. you can use the oil..??? butt only if you follow ..( Jeremy Clarkson's info ) on car diesel prog.. one cap full of turpentine per litre of oil. but must leave over 24 hours so the two become one .. lolol. ? with a good shake.. ho. ho. but it works. WE HAVE TRYED IT ( better if use diesel up to 45% max oil. but not old sump oil... no no no ... sump oil has to much carbon in it and blocks the dam filter... and it stinks out your neighbour's.. ho. no don't do that
We know those heaters are able to burn all kinds of fuels but they build up residuals of carbon and deposits that are hard and don't burn clean as diesel, so why are so many people trying to burn all these things? We already know it doesn't work long term with any great success. Some just have to learn the hard way I guess.
I had a question, I typed it into youtube, it has been answered. Grand stuff.

Used cooking oil works great I’m thinking that the hydrogenation process adds moisture that is eliminated from cooking

David, thanks for the video. Loving the honest results! 😂
Can you run on a mix of diesel and veg oil???Try prewarming the veg oil off the exhaust, that is what veg oil vehicles do.
Use an Egr / radiator from a car/van to warm the veg oil up and do the same with waste oil
Yes you can and this is wise to do when it is colder as the viscosity of the fuel/oil increases the colder it gets
I wonder what the error code is for carbon monoxide posioning ?
Code Blue, Code Blue!! 😅
Actually it's cherry red in the face. By the time you're that color, it's pretty much too late for you.

Yup...a fail...way too much smoke. Love your videos
Thank for trying. How about starting on diesel, then switching to a Diesel / Petrol / Veg mix. Say 10:20:70
Try E85 now for crying out loud! Or a least a mix of that and diesel. :) Keep them coming!
Oh you'll like Tuesday video then. ;)
@@DavidMcLuckie o happy days are coming! Wohoooo!! :)
Great stuff, thanks for trying the experiment, I've run mine on paraffin, was thinking of mixing with veg oil, you tried that?
does the heater run on diesle and caster oil and produce that lovely race fuel castrol R smell
I was wondering would it work if you mix one litar of used vegetable oil and four litres of diesel
Thank you for trying.
I see your next video is what ratio of Petrol to Veg Oil, that veg oil wasn't burning fully hence the white smoke and sputtering.
Preheat your veg oil at 80°c before injection. Start diesel=》switch with veg oil preheated.
Sorry for my english.
Maybe a good idea to switch the extractor on before the smoke ?
You would think.
Used vedg oil is a different story as it will contain water particles ect.. So it has to be treated and more

So why would you uses vegetable oil when it cost more than Diesel?
It was to represent used vegetable oil. Which would be free. But I didn't have any used veg oil.

Perhaps the height is too much for the fuel pump?
I know the pump has to be on an angle of 15 to 20 degrees to run properly,
Did you prime pump first

Can you get untaxed fuel oil?
Yes. Ours is commonly known as red diesel.
maybe you need to run vegetable oil with more air?
hi. and sorry i forgot to add .. as always.. a big thanks to you for all of the help.. yata yata .. bye.. tone
Have you tried with heated veg oil?
Do a 80% to 20% need some diesel to thin it up or kerosene

Veg oil now is £2 a litre
Which is about 4x time what it was when this video was made.
Oh well, that didn't look very healthy, dread to think what it's done to the insides
Yeah, it'll need a clean with thinners or brake cleaner, perhaps both. :)
Dam cleaning your insides with thinners sounds painful hahahaha
And all the fresh oil in the world won't make any fockn' difference!
Cooking oil is as non-flammable as possible.
Please get a carbon monoxide detector for your shed
Currently have three varieties running just to be safe. The heaters running don't produce that much CO if tuned properly.
Pointless. Diesel £1.80L cooking oil £2.16L
You are aware how time works?
@@DavidMcLuckie yeah I used to watch Dr Who
600 litres free wvo here and only just one week and couldnt keep up with the amount of fryer shops wanting to give the stuf away!
Run exhaust out side you will elimate the chance of dieing
Thank you for your concern. Rest assured I am aware of CO and how it works.
