Thanks for sharing your experience. I too am just starting to learn about CDH and look forward to learning from your experiences. You’re doing a good job of conveying your thoughts without a lot of fluff. Keep up the good job 👏
Appreciate it bud. More to come soon for sure.
Nice... we are headed that direction with our RV as a backup heater source. Thanks for posting!
They are great for RVs and vehicle installations. I wouldn't run it on oil for that... keep it on clean diesel and you wont have any issues out of it. They sip fuel
Glad it’s working out well for ya! 👍👍👍🇺🇸🇺🇸🇺🇸🙏🙏🙏
Sorta. Lol. More on that soon
I been awaiting this moment thank you
Hold up on doing anything until the update video comes... It's having issues after a single tank (which I kinda figured it would)
i blend mine 50/50 wmo to diesel it runs fine but be prepared to clean ash out of it every 5th day
Yeah I'm sure it'll happen
As long as a person doesn't mind cleaning them out. Running wmo is no big deal.
Lots of carbon buildup inside the burn chamber and entire exhaust tube. It needs to have 2 tanks, diesel to start and flush afterward.
Yes.. yes indeed. That's coming soon
@@NotSoGrandGarage
Adding to what @1FishinAddict said, make sure to not only start on diesel, but also wait to let the unit get fully up to temperature before switching to oil. Conversely, when you switch back to diesel (as part of your "pre-shutdown procedure") be sure to let it continue running on diesel so you not only flush the oil out of the fuel lines, but also let the burning of diesel fuel burn off some of the residual soot that has accumulated from the burning of oil. When I do this, I intend to let mine run on diesel for 30 minutes (at it's highest setting to give some time for some of the soot to be burned off, and then some time to allow temperatures to stabilize) for both startup and shutdown. Finally (for a number of reasons), I would also suggest only using oil that has been filtered to 2 microns or less.
@@ktraglin Will do. I've got everything sitting here to setup the dual tanks. We'll see if I can get it running well again as it's struggling right now.
That doesn't work either. I didn't have an issue starting on waste oil splash of gas diesel mix. Worked for 3 nights then overheats due to amount of unburned hydrocarbons and ash covering air inlet in burn chamber all settled to bottom blocks half inlet. Causes burning well past chamber and overheat
@@jaysonhoulihan9808
Starting on waste oil (including blends) is problematic because it just doesn't burn well enough until it's up to an appropriate temperature. During the time it takes to get up to an appropriate temperature, it creates way too much soot, carbonized fuel ("coking"), etcetera.
Even before getting to that, though, there are two other things to consider: First, filter the oil to two microns before attempting to burn it in this type of heater. Second, "tune" your heater by adjusting the maximum and minimum pump frequencies to maintain proper operating temperatures. I tuned my unit using something similar to the procedure outlined in this video, titled, "How to tune a Chinese diesel heater with no tools 2kW & 5kW" th-cam.com/video/SmCYQu53umk/w-d-xo.html
Been waiting for this one!
Updates coming soon... it's struggling already after a single tank. Have some plans though.
@@NotSoGrandGarage
I'm here for it!
@@Wrenchmonkey1 Appreciate it!
This is the guy i want to hear the facts from!! A ton of the other videos are initial setup only or if they do have a follow up its them burning thick dirty oil etc. If these can be made to work it sure seems like dual tanks, filtered, and not running them on low and tuning is the way to do it
Appreciate that. Yeah I'll be setting it up on dual tanks as I'm having issues with it already after a tank and a half of 50/50. We'll see what happens. Updates to come soon.
@@NotSoGrandGarage if anyone can make these work (and share how) it's you!
Got me one of those style heaters last year. Goes through about $20 of red diesel a week. Setting #3 and #4 seem the best balance between fuel consumption and heat production for me. Stinky fuel or smoke means the burn chamber is fouled. Take her apart and site brush it clean. I got a different fuel pump that works better. Amazon
Thanks for the info and for watching
I appreciate the video. I’m getting ready to order a couple of these myself. I’m cutting firewood yet I have two IBC totes full of diesel in the backyard. I can’t help but feel like I’m working too hard
Nah.. I love wood heat. That wood is cheaper.
It’s better to have it and not need it than…..
Indeed.
I could get about 3 nights before having to clean burn chamber. Tried many different mixes. I was hoping to find one that works and stumbled here
I've got a fair bit of playing to do. We'll see what happens but your time-line lines up with my first experience.
When I bought my first heater this year, I ran it on diesel for a few months until last month I was with some friends late at the shop and we ended up setting up a side fuel tank to test what we could burn in it. Long story short it drank unfiltered motor oil, gear oil, grease, atf, gasoline, mystery oil that definitely had some sort of water in it, and maybe some form of drinking alcohol... I can't remember, but all I know is now it starts hard and smokes pretty good now, so I'll clean it out and just stick to diesel for this winter since the thing uses so little fuel it costs nothing to just run red dye in it.
Lol... sounds like an interesting night in the shop. Yeah it likely needs a good cleaning. Mine does as well. It ran great on my oil blend for a tank and a half... then nope.
@@NotSoGrandGarage Yeah, I found that they just don't get hot enough inside to burn off the additives in oil and it builds up in the middle of everything.
Most heaters come with tin plate silencer. Have 2 and put one on the inlet as well as exhaust. The inlets are quite noisy.
I've got a few laying around. We'll see
I have yet to set my heater up...or even mess around with it. I bought it a couple of years ago and sort of forgot about it to be honest.
I like the idea of it being portable/movable for storage in the off season.
Yup. Should work well. We'll see how it does
Can you modify the speed of the burner fan and the pump frequency?
I think so. I haven't dived too deep into the control side but pump output and such appear to be adjustable.
@@NotSoGrandGarage you want to keep the burn chamber temperature as high as possible and the afr rather lean so soot doesn't build up too quickly or at all
How is this diesel heater comparing to the fuel shed heater from vevor? Have you been able to run that one on black diesel for extended lengths of time? How do you feel about quality of build between the vevor and this unit?
No oil in that one. Build quality is the same pretty well.
So you have been running it on pure diesel fuel?@@NotSoGrandGarage
@johnstudinski correct. It sips fuel so it's cost effective. This is my first time toying with oil in them
About how much fuel per hour?@@NotSoGrandGarage
You will be getting petrified build up in the burn chamber for sure. I've tried diesel engine oils, petrol engine oils, gear oils and also the headstock oil from my lathe. It all turns to shit in the burn chamber. Having better results with used cooking oil and diesel at 1:2 mix.
Oh it did. Lol. I'm going to try a dual tank setup. This is all just for giggles really
Any update on this ? I have a ton of experience with burning WMO and made a entire 30 part video series on it.
Some of the outcome depends on the quality of your oil, but in general, you will be able to burn about a gallon of actual oil oil, regardless of what the mix ratio is. If you dilute it 50/50, you get twice as much time, because you are burning half as much oil, but X amount of oil produces X amount of ash.
These heaters have two main issues with burning oil. The first one being that the wick area doesn't get hot enough to flash oil off at the same rate as the diesel and or gasoline. Second being that they are very particular about restrictions to flow. It only takes a small amount of ash to cause things to spiral out of control.
You might get away with cleaning out the chamber a few times, but after doing this a few times, carbon will form in the wick area like concrete. It is pretty hard to get out, so this usually means replacing the chamber, unless you want to take drastic steps and chop it apart. The first time it may last for 40 hours... the next time half of that, and then half again.
Countless people think they are having success, and sadly announce to the world they are, because they have run their heater for 30 hours with 10% oil... but I have talked to literally dozens of people who have tried and failed.
Dave McLuckie has done a series on WMO as well.
It coked up pretty quickly and I havent messed with it much. It's pretty warn here now so haven't needed it.
I've got 15ish years of wmo experience as it stands... but I'm typically running engines... not picky little heaters. My fuel is triple passed through a 6k rpm centrifuge at 180F... lab tests show it being cleaner and dryer than the fuel at the pump... but as you stated, oil doesn't burn clean unless it's HOT... and these heaters struggle in that regard.
I'll check out your series on it. I've got a playlist dedicated to my process and the vehicles powered by it. I'm also a WVO Designs dealer so of you need anything, hit me up.
Thanks for watching and commenting.
@@NotSoGrandGarage Yeah... I was going to say "running in engines is a different thing" but I didn't want to step into your territory and pretend like I knew... I'd just be guessing.
I have actually made some progress, but had to modify the heater to do so.
I would like to get into some WVO stuff at some point... I find it fascinating. The WMO tests came about because I am a small engine mechanic and have a steady supply that I normally have to dispose of.
@loweredexpectations4927 I've talked to a lot of people who run veggie in them without issue. Veggie typically burns clean.
With t hat s aid, I haven't looked yet but have you tried preheating the oil? My next phase was going to be dual tanks and preheating the oil side right before the chamber (probably using exhaust heat).
@@NotSoGrandGarage Yeah. I have done the preheating with two tanks, temp probes on the chamber to monitor the temp of the area where the fuel enters, as the exchanger is not a good reference. I ran a piece of brake line through the fins on the exchanger so that the temp was limited to a max of 236C (My ECU shuts down after that).
If you use the exhaust to heat your fuel you want to make sure your fuel line can withstand fairly high temps. I have seen my exhaust glowing red hot. Even at 200C, I had issues with the fuel gassing off and causing very erratic feeding. If you are adding gasoline this will off gas. The fuel can't go back to the pump, so it shoots into the chamber, then you are left with an air pocket and the heater will either flame out, or lose a lot of heat and start smoking really badly.
What can help is using an industrial aquarium pump (or paint gun air regulator set to about 6-8psi) to feed the fuel through the heater line with air. T into the fuel line just before the heater. The air will pick up the fuel and deliver it at a steady rate. This isn't a magic cure for ash... but it takes care of the erratic feeding.
@@NotSoGrandGarage Some veggie oils are better than others. Grapeseed, cottonseed and peanut... I believe. I'm no expert, but my understanding is that the glycerine does not like to burn. I did some petri dish testing, and it takes a lot of energy to ignite... once it lights, it seems promising, but about 1/3 of the way through consuming the fuel, it souldently takes a LOT of heat input to keep it burning.
I suspect if you dilute it with kerosene or maybe gasoline, this may help, but have not testing it myself. I have been talking with one gentleman who has been messaging me for over two weeks ... He started by saying "it's running swersome", we chatted on and off and I asked him to keep me posted... He contacted me 2-3 days ago saying his troubles had started, in the exact way I said they would... and that he will let me know when it quits.
Most people are more than happy to tell you about the 2-3 days, 16 hours of success, but are then embarrassed or something to give the rest of the story. I suspect there are some people successfully burning some types of veg oil.
I tried really hard to make this work but was un successful. Dual tanks with valves, centrifuged oil. Switched to oil after heater was heated up, switched to diesel a few minutes before turning off. Tried w90 and 50% diesel still sooted up. Ran only on high
The only thing i didnt try was heating the oil tank and my heater was outside not in the heated space.
I think lack of pressure and combustion is the limiting factor. Waste oil heaters work great but they used compressed air for atomozation, engines obviously have injection pressures as well as combustion factor in the cylinder. The flash point of oil being higher lack of atomization and combination cause it to just not work for any extended period of time
I really wish it did tho. It was a real bummer for me after my experiment
Im tending to think cdh just for diesel. Cheer yourself up by building a blue flame waste oil burner.
Yeah after the first tank, it started struggling. This video is behind thw experiment so we'll see if I can figure something out with it
I've thought about it. I may one of these days
@@lyndonchambers2301 yeah I've thought about the blue flame heaters. What I really like that I have seen is where people build a box around a barrel put pipe in the barrel connected to a blower to defuse the air plus the blower blows around the barrel into the box into a duct blowing inside. Unit is outside
Probably doesn't make sense the way I am describing it but I looked pretty well done
Similar to blue flame kinda
@@NotSoGrandGarage order a pack of the atomize screens for when you clean out the burn chamber. I wasn't able to successfully clean those screens so it's easier just to swap them out I found
Great way for using the exhaust heat
m.th-cam.com/video/X6UvlAmGliM/w-d-xo.html
Make sure the outside end has a good slope down so no moisture collects inside.
The condensate is acidic. You can use the drain (legal) or use it for pest control
Interesting for sure.
Has anyone actually got it to work properly? Can you link me to that video
I've talked to some that claim to do it long term... but IDK. No links yet. Mine failed after 1.5 tanks. I'm going to tear it apart soon for cleaning and we'll try again.
There must be a hundred videos of people trying to burn motor oil in these heaters and find it does not work long term without constantly taking it apart and cleaning the burn chamber, atomizer screen and glow plug. So why are so many still trying it? It's a diesel heater, so why not just burn diesel in it? WTF?
Take 5 minutes and see what the majority of this channel is about. Half of the content is dedicated to alternative fuels. I don't really care what others are doing. It's for the sake of testing. The heater didn't cost me anything.... and my viewers are different from viewers of other channels. I've been asked multiple times to do some testing.... so that's what I'm doing. Thanks for the input and for watching
@@PainterD54 because I was asked to.
@randGarage Do you always do what people tell you to do? Well there you go!
@PainterD54 I get what you are saying... and yes it's likely a waste of time but for some reason, I've got a bunch of people in my comments section asking for my take on it. Might as well give the viewers what they want.
