@@kevinedwards4449 What do you use for cleaning/prep now, instead? I just got an arc welder. All I'm doing so far is making practice beads on junk scrap. (I know not to weld on galvanized metal.)
phosgene is some hardcore death metal shit, seriously. there is video on youtube about leak at a 3M plant once. apparently it can eat through stainless steel braided hose.
Since this video was posted a year ago in 2023, you have probably already solved the problem. I am still learning about these heaters myself. My manual does say that they cannot be .mounted sideways and operate correctly. Due to fuel pooling in the burn chamber. Just something to look at. Thanks for the video on disassembly and cleaning of the heater!
I changed all my led screens to the blue screens with the spanner in the top left hand corner and the led remote, which allows access to the special settings menu. The heater ecu also has to be the blue board with the bi metallic silver strip tuning across it, I now burn exclusively kerosene instead of diesel and service the burners every summer cleaning the chambers by filling with oven cleaner leaving to soak for about half an hour then rinsing with water 3 times, this removes any large carbon deposits trapped in the burner. I then blow the burner dry with a heat gun and resemble.
Ok, there's a number of things not ideal in your setup. The fuel filter is the wrong way round and should be close to upright below the pump to eliminate air bubbles and give the pump an easier ride - it will be quieter too. Also check the voltage drop from your battery on startup, if it is dropping below 12v then your glow plug isn't getting hot enough to ensure reliable ignition. If you fix all of these things and still have the same problem i suspect that the glow plug mosfet on the control board has begun to fail and isn't allowing enough power through. I had one to fix last week that was doing the same but didn't respond - turns out the guy had pulled the wiring harness too hard and had broken the copper wire inside the sleeve so that also caused a lack of power to the glow plug. These are wonderful machines and it pays to have a full kit of spares if you rely on one.
@alaskanhomesteading And if I may add, the controller - mainboard combo you have is a "dumb" type so if you go to ali and get a mainboard, your controller will not work and issue an Error 7. You will have to get a full new pair, these are called "smart" and are compatible with a wide variety of controllers. On a side note, which elevation are you? 185c chamber temp is too low and should be 200 - 220 nevermind which power setting you have, 1 or 10. This might be fixed by enabling altitude mode ("plateau mode"), search the net for that, it's some hidden menu somewhere. Good luck!
I'm in Newbrunswick, Canada and run a vevor diesel heater to heat my mancave. I find that the filter for the intake that vevor provides is garbage in extreme cold conditions. The filter collects ice crystals in turn, clogging the filter and suffocating the system, causing extreme smoking. I removed the filter and have had no recurring problems. Once and awhile, it is also a good idea to run your heater on high to burn off any soot in the system...
You’re having incomplete combustion. It’s burning rich leading to the unit coking/sooting and this gets worse over time. You need to introduce more oxygen to burn cleaner and hotter! Carbon build up reduces heat transfer in the screen, the ignition/burn chambers, and the metal housing. It never gets up to proper operational temperature resulting in a “cold blooded” machine. Just like an internal combustion engine, carbon build up will destroy your machinery eventually. Carbon is a thermal insulator. Many high temperature coatings use ceramic and/or carbon to protect against over heating or melting. Research stochiometric burn ratios if your doubtful. The fix: 1: Disassemble and clean. 2: Install new burn screen. 3: replace gaskets as needed. 4: Inspect the tiny ignition chamber where the diesel fuel enters. Nearby you’ll see a hole with nothing inside it leading to the ignition chamber. Be sure this hole is NOT obstructed in any way. Be very careful to completely seat the burn screen all the way down into the ignition bore. Look into the air port (you should not see the screen or any obstruction!!!). 5: Before you install a new burn screen do the following: Drill this hole to a newer larger size. Be sure you do not damage the fuel port, glow plug threading, or screen. Consider drilling another hole 180 degrees apart from the factory air port. The default design and machining from the Chinese factories are very sloppy. These units burn rich straight from the factory because of this lack of attention to the air port in the ignition chamber. 6: Look at your exhaust system. It should dip down at least 1/4” every foot or more aggressive with no traps or dips to allow soot, water, and diesel to drain from the exhaust system. Also the mufflers design is meant to be installed in any orientation. However the original designs told their customers to drill tiny drain holes in the lowest spots to allow drainage. These D2, D3, and D4 designs are of Western origin that had the patents expire. Once that patents expired the Eastern companies copied the Western designs but poorly with out providing proper customer instruction or machinery documentation. 7: Use larger gauge copper multistranded wire/conductor. You need to eliminate or reduce electrical resistance as much as possible. Go with the largest wire gauge you can. 14-10 American Wire Gauge is a good place to start. The longer your wires the larger the gauge you need. Also charge your batteries. If possible add more batteries in parallel to your battery bank. By adding more batteries in parallel you increase the electrical “flow” or capacity. If you run too small a battery bank you’ll lose capacity and then voltage will quickly drop. Or consider buying a cheap AC to DC wall plug adapter. Look for 12 volts @ 10-30 amps if possible. 8: Look at the glow plug itself. You’ll see the wires loosely wrapped around the ceramic glow plug rod. If possible find high temperature solder around 500 F - 1000 F (or higher if you can) and solder the glow plug wiring to the glow plug rod. This will destroy the clear poly shrink tubing they use as a safety insulator. I use Permatex room temperature vulcanizing (RTV) copper orange. This sealant only protects up to 600 F intermittently. It will last for a year or two before the copper orange RTV breaks down. 9: As others have mentioned, consider using a diesel additive. I use Diesel 911 as it prevents diesel gelling in cold weather, burns hotter, adds lubrication for the needle pump/injector, and it’s cheap per dose. One bottle typically doses 50-500 gallons US depending where you purchase it. It’s typically 16-40 Ounces in a package and you’ll only ever use 1-2 ounces per fill up or less. I dose my 6 gallon tank at 1-12 ounces and I love my results. 10: Inspect your fuel lines! Do NOT use typical orange/green/yellow soft fuel lines. Use the 2mm nylon tubing and 3mm rubber hosing to make connections. If you’re feeling fancy you can run the fuel lines in 2mm copper or titanium. The copper is said to clog because copper and diesel are thought to be incompatible. My copper line has had no issues over 8 years of use. 2mm Titanium is the premium material but it doesn’t bend readily and you must follow strict process to bend it accordingly. I live at 5280 ft elevation with lower oxygen/air pressure. After I enlarged the factory air port and drilled another one opposite into the ignition chamber my start up and smoke problems are gone!
Hi,I had similar issues, part of the unburnt fuel clean up also involved cleaning ext air intake and choked exhaust, I do realize your very helpful video was cleaning the unit only. Great video thankyou
In my humble opinion there are too many inconsistencies with the quality of the heaters which can make troubleshooting a little tricky. By that I mean that sometimes you get a good one and other times you get one that doesn't function correctly. I have 3 that look identical, however they do NOT operate at the same level of efficiency. My 1st unit sooted up after a very short time and began to give errors. I still haven't taken it apart, and I don't remember what temperature it operated at when it actually worked. The 2nd unit has been running flawlessly now for 60 days of 24/7 use and the internal temperature reads 405°f pretty consistently. The 3rd unit has worked flawlessly as a backup. However it's internal temperature varies between 325°f and 380°f. The internal temp will rise as you increase the heat settings. I have only ever run clean diesel or home heating oil. Great video!
I buy a diesel additive (i.e. Kleen-flo) and add a capful to every fuel tank. It significantly reduces the smoke at start-up and also reduces the soot and carbon buildup in and around the burn chamber. It is so effective, I can no longer tell what stage my heater is in by watching the exhaust.
I had been wrestling with the same problem for a couple years but finally have it solved. Problem was not enough air getting through the little hole next to the glow plug. After enlarging the hole to 1\8 inch it starts every time.
@@brunoteixeira6408 Yes, seriously. No white smoke (vapor) since enlarging the hole. Ignites quickly every time. I have 3 heaters and it works on all of them. I'm at 4000' elevation BTW.
You can use other fuels, but only if you adjust the air-fuel ratio properly to match the fuel. A lot of people are on here trying to use waste motor oil, but not changing the air-fuel ratio, and then showing how much it failed. In order to change the air-fuel ratio, you have to get into the secret menu, if you're controller will allow it, some don't. In the secret menu you can change the fan speed and fuel pump speed relative to each other. There are people on TH-cam that explain how to do this. It may not start on the other fuel, so you have to start it and stop it on Diesel or kerosene, or a mix. A lot of people use two tanks and valves for this purpose. Although it's best to have the inexpensive tools, you can typically get the screen out with a lag bolt. Using antisieze on either side of the gaskets will help keep them from sticking for next time. Good luck and have fun with it!
Awesome, thank you for the great tips! I have monkeyed around in some "Secret" menus in the controller, but they were mostly indecipherable. Now that I understand these devices a bit better I'll have to revisit that.
Anti-sieze ! What a great idea !! I need to service my little 2Kw unit now, same problem, and although I've got the kit coming in the mail with gaskets & stuff, I thought I'd run a thin bead of Permatex Red Gasket Maker silicone ... if I let one side form a skin then I'll add a small amount of anti-sieze grease 😊 Cheers for the video 👍
Old baked on cooking oil residue is best removed with oven cleaner. Carbon buildup responds well to brake cleaner. However, a brush set is a required tool along with a pipe cleaner and toothbrush.
Your problem was trying to burn vegetable oil, doing that blocked up the bleed air hole and it was a downward slope from there. You should run it at full power BEFORE turning it off, not turn it down before turning it off, the more it runs at full power, the less build up you'll get in the burn chamber, that heater was pretty clean other than the starting circuit being gummed up from the veg oil. If you get into the settings, check the max fan speed is 4000 or less, the motor won't last long over 4K rpm, drop the max fuelling a point or two if you reduce the max fan speed to ensure you don't over fuel it. Yes the fuel filter is technically the wrong way round but the mesh is so big that it won't make anydifference, don't worry about the air bubbles in the line, the pump created them, but it keeps pushing fuel in one end si it can only come out the other end, the heater won't suffer for a few bubbles in the line.
On my Vevor heater manual, it says not to mount the heater sideways or upside down. It says with picture diagrams to only mount it straight with exhaust and intake ports pointing down toward floor.
There is also a screen in the other holes you were jamming that tool in, and if you damage that, you will have to replace the whole burner. The best way to clean that screen out is to burn the entire end, and get it red hot. Mine starts up like that too, and usually after I haven't used it consistently. It usually always starts, after the second attempt. I've had it apart several times and still can't figure out why. It has always come apart clean tho with very little soot, and for the most part it is on low, with an occasional high run to warm things up quickly. (I live in Western Wa State.) If you coat the gaskets with graphite, they come off without damage every time. I've had my 2k for about three years and I love it but I can't run it unless it is below 40f.
You might want to try Easy Off Heavy Duty oven cleaner for cleaning your parts if you aren't in a rush. Spray it on and in, and walk away for an hour or two. Wipe it off, or give it a rinse. Much easier.
It's a simple enough design, so making a competent copy isn't that hard. I suspect the biggest quality variability on these cheap units is in the electronic controls and the programming in them. The other stuff is commodity. Cast aluminum, injection molded plastic, and a heating element and temp sensor. It's dead simple stuff.
only thing that's happened to mine is burnt out glow plug, last about a winter season, i just blow through the intake and exhaust with my compressor. great heater for the money £69 when i got mine. i do have to remove the lcd control panel and wrap the screen in a cloth or the cold stops the screen working, but if i for get the cloth or a cold snap drops i have to use a hot air gun to gently heat the screen a minute or two.
Looking at your fuel line it looks like you are pumping alot of air bubbles to the heater. I suggest you mount it vertically so it will run without air bubbles, lubricate the pump piston better (so it won't prematurely wear out) and run a little quieter.
Greetings from Banchory Scotland. Looks like your fuel filter is fitted the wrong way. It will still work but makes it difficult to see contamination on filter screen. Suggest you invest in a water separator fuel filter. Also get a coach screw to make removal of screen easy. It is ok to run heater on its side the way you have it fitted.
I have been using a blend of kerosene and some hot shots extreme or stanadyne all season additive. You need to have a 20 to 30 % kerosene to diesel mix. I have been doing this for a number of years and I have found it to be very successful. Also have the correct settings for your altitude. The trick is to have it burn hot at the low speed and not to flood the burner chamber. Understand that they do need some serviceing from time to time usually just replacing the atomizer screen and making sure that your air intake and exhaust are clear. The Espar unit recommends using straight kerosene for 30 minutes and that will help to clear the screen. If you want the altitude settings check out utube.
There’s a hole next to the glow plug this hole blocks up and the heater will fail to start. You can clean that hole out without stripping the heater down or having to remove the glow plug. All you need is to remove the rubber boot on the glow plug hole and with a bent bit of wire locate the hole and poke the wire in it to clear it. Now this is an issue with this design of a heater and they do leak co2 into the hot air out let. The main course of this is exhaust back pressure so if you have a long exhaust run it’s more likely to soot that hole up and the heater will carbon up inside.
very similar to a diesel particulate filter vapouriser. glow plug and a spray of diesel to burn out the soot of the exhaust filter. gets the exhaust up to 600c
FWIW, just from the brief glimpses of your fuel filter, it looks like it's installed backward. The filter will work in either direction but if used in the backward direction, the debris and sediment you are filtering will be collected on the inside of the filter element (the side you can't see) and it defeats the purpose of the clear housing because the filter will always look clean. If I'm wrong, please ignore my comment.
Drop a link to what you found. Is it the Afterburner? I've been looking into that one, but neither of the heaters I have are compatible with it. That system requires a very specific control module on the heater. I may resort to buying a compatible module off Aliexpress or something.
A lot of people take that screen out, especially if it gets fouled. I have never in three years taken mine out. I have burned it off once in all that time, and it spends most of the time on low. I have a 2k inside a well insulated 8x16 cargo trailer.
You are 100%correct. Unit needs to mount right side up. Any suds cabon will gravity falls out of burning chamber. Even installation manual mentioned this
If you ever have to do this again, I would get a gallon of chemtool carb dip and let the burner sit in that overnight before cleaning. As someone else said, you may have dodged a bullet with the brake cleaner this time, but yeah people have died (slowly and painfully) from welding when even small amounts of brake cleaner are present.
Did you consider running a copper or aluminum exhaust pipe line from heater at an angle across a longer space to near the ceiling then exiting building so heat radiation loss is to the inside of building rather lost going directly outside?
@@guestguide2544 I have heard mixed things about that. Some people mention potential issues with excess exhaust back pressure from this. But I've also seen people run the exhaust through an old radiator, soooo.....
HAVE YOU EVER THOUGHT ABOUT WHY THEY DO NOT USE COPPER FOR CAR EXHAUST? The reason is it is against the law in some countries and gives off a poisonous gas at high temperatures.
I know in this case the brake cleaner has had no problem at all breaking down your gunk but for baked on carbon, I have found carb cleaner to be far more effective, brake clean would not touch the crud on my cars intake manifold but it dissolved quickly with carb cleaner.
Couple of questions though not yet half way through the video. First…can you provide information on these rebuild kits? And second…would you tell us everything about that snow roof rake!?!?!👍🏻
Here's the rebuild kit I bought. hwww.amazon.com/gp/product/B0BLG8MXWJ/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1 The roof rake is pretty great. I've used it to clear off my greenhouse and high tunnel when we had excessive snow load.
@@alaskanhomesteading okay…I’m confused. The video you linked is for a hydraulic fluid change of your Branson tractor. And, the snow rake… and name I could research to find one to buy? I have a Kioti tractor but, I did look at Branson. Our only local dealer was not very convincing of customer service… so I ran like Forrest Gump!
@@keithrayeski6417 LOL. Copy/paste fail on my part. Someone had asked me about a hydraulic filter on another of my videos, and I was copying that link for a reply to him. I updated my reply to you with the amazon link. I'm not affiliated or anything, but that kit seemed to do the job. I forget the brand on that snow rake. I got it used off facebook marketplace. The one most people seem to like more is the "avalanche" snow rake, which includes a sheet of plastic that slides under the snow, to help it fall off the roof. With this one, you really have to pull the snow backwards towards you.
Hi I have the same heater but mine after 2.3 hours of operation the fan starts over speeding and fluctuating the speed up and down even the heater has the same speed setting and finally the heater shuts off and my it gives all the smoke from the combustion chamber on the intake pipe and very strangely, no error code. What do you think
10 วันที่ผ่านมา
I use one for heating my greenhouse i use central heating oil instead of of diesel as it works fine and is a lot cheaper, the only problem i had was with the voltage the battery system went down as i use a charger to keep the battery topped up and i didn’t realise that the charger had gone bad soon sorted with a new one and back to normal .
Big mistake using a flame with these solvents, certainly asking for trouble. I've plenty of experience in cleaning out soot from Diesel heater steam cleaners, a good wash with alkaline traffic film remover and a pressure washer will remove any debris and it's safe. Dry thoroughly and replace atomiser screen properly so it doesn't block the air intake hole, fit a new glow plug as a matter of routine. Don't mix old veg cooking oil as the flash point is higher and can gum up the atomiser screen. Kerosene is fine but 5% two stoke oil might be a good idea to lubricate the fuel pump or 20% diesel. Have fun
Hello if you please can you tell me how much hours work in good situation before maintains and which level from 1 to 10 work good without cock get in ....are you understand me?
@@firashejazi2869 I understand, yes. I don't know the answer as far as hours, but the general guidance seems to be to run at higher levels to avoid coking.
@alaskanhomesteading No i think in level 4 is good for consumption of diesel and 90% burning...if you search on China website they told that. Have a good day
if you increase the voltage to the heater to almost 14 volts, your sooting , and error codes will go away. the higher voltage will make the glo plug hotter. thus burn cleaner, less fuel consumption.
I bet that's part of the problem. The car battery I've been using is quite old and tired, so if I haven't had it hooked up to the charger, it will not perform well.
@@Timetraveller1010 you'd really have to connect it to some kind of regulated DC power supply to do that. Car batteries just don't sit at that high of a voltage, even on a battery maintainer.
I'll have to try that next time. Once I got it out I noticed that it's a little rolled-up length of screen, so it makes sense that you could twist it in a direction that would tighten the roll and shrink its outer diameter, making it easier to remove!
@danielcleaver9349 it's a good point. I have in fact been considering either a LP or NG heater for it, but the diesel heater was a fun experiment. The H2O and CO2 put off by any gas burning appliance would definitely be very nice for the plants!
@@alaskanhomesteading Consider this. Propane while nice to use, is so danged expensive to use. About 2-3 weeks ago, I bought one of those torpedo propane heaters to heat the garage. It worked wonderfully. BUT, in reading the manual, that heater, on low, would only run for around MAYBE 2 hours on a 20lb tank. Where I now live, filling one of those is around $25 ish. That's just too danged much. That's why I'm searching for one of these diesel heaters and pretty much, with all the info that I've researched, I'll probably go with the Vevor as well. I'm just not sure if I want that style or the all-in-one style. I am leaning towards the all-in-one as it's really easy to move around if necessary and not necessarily make a permanent install. Besides the cost of propane (need bigger tanks, long runs of tubing, etc) for me, there's the issue of having "open flame" inside the garage where there are flammable liquids. Actually, I think that's this is even illegal in my parts. (I should check that out). Yours is one of the videos that I'm saving in a folder for future reference in case I buy one. You made it look easy cleaning that chamber. As for cleaners, I've seen people using *DPF cleaner,* which I understand is specifically designed for diesel engines in that it can literally dissolve all the buildup materials.
You talk about problems with it not picking up the fan spinning yeah there's a magnet on the fan and then there's a little sensor and I had the issue of mine becoming loose on the shaft and sliding forward and then the sensor couldn't pick up that the fan was spinning anymore and was shutting down I slid it back so that it was as close as you can get it without it actually rubbing on sensor and put a clamp on fan so that it wouldn't walk off of shaft anymore and haven't touched it in over 4 years
How is your pump mounted? It must me vertical not on it's side or low pressure bubbles will rise to the side and wear out the dosing pump..they dose 0.2 mill litres ea pump and the dose will be incorrect..and destroy the pump.. Don't restrict the intake at all and 0 bends in the exhaust..straight down! You have a combustion issue, back pressure..
Diesel fuel has a smaller molecule even than gasoline and when you mixed vegetable oil with it, It probably gelled and plugged the screen. If you ever want to find a leak in a gas tank, pour some diesel in it and you will find it if it has one. I hear jet fuel or kerosine works well in these heaters. I wouldn't play around with non flammable solvents with flame if I were you.
Do not-Do not-Do not heat break cleaner. Those vapors can be very fatal, very fast. Phosgene gas is the same chemical used in WW1 chemical warfare. Another cheap but flammable cleaner is carburetor cleaner, also found generically at Walmart and is leaves no residue. It is a superb paint gun cleaner also.
Brake cleaner does not leave residue. That's literally the purpose of it. Don't want any contamination left on brake parts! Let any wet cleaner flash off before reassembly and there is no brake cleaner remaining on the surface. If there was any left inside and the heater started up YOU'D KNOW ABOUT IT. Boom!
My unit refused to start after only some 200h. I used it at low power and only pure diesel. How many hours did yours run? And at what setting? Medium/ full power? Or ?
I don't have a count of hours, but it was only at level 4-5 most of the time. 10 is its highest setting. As others have said in the comments, it is apparently important to run them hot to keep them cleaner.
If you are filtering your fuel and intake air, you should not be getting such a buildup inside the exchanger. Keep things clean (and don't burn anything but diesel in it) and you will be good to go! So many are burning waste oil or veggie oil mixed with kerosene and other kinds of fuel in those heaters and wondering why the buildup? Well, they're not made to burn that crap! It's a diesel heater made to burn diesel.
My first guess would be that the fuse is undersized for the load required by the glow plug. I've read that they pull about 10 amps, so if your fuse is smaller than that, it won't work. If the fuse is over that size, then I'd be looking closely at the wiring harness for any shorts or damage. If nothing obvious shows up there, then I'd look at the circuit board on the control board, which is pretty easy to pop open. That's the board ON the heater, not the display device with buttons. If something is damaged on the circuit board, it will often be obvious. E.g. charred or discolored components. Failing all of that, I'd take a look at the glow plug. Measure the resistance across the glow plug wires and see what it shows. The resistance should be something like 1 ohm, or maybe a little less. If it shows as a short or open circuit, the glow plug is no good. That's just how I would start troubleshooting it personally. I haven't experienced this problem.
Why is it so dirty? How long has it been running before you cleaned it? Are you filtering your fuel? Just wondering how long I should run mine before I clean it? Thanks for the vid!
I used it for a couple of months, running sporadically. I think the main issue was my failed experiment trying to use some vegetable oil in it, which I definitely do not recommend!
air intake for combustion should always be outside with the exhaust. Heaters dont like pressure differences and there can be smoke from the intake sometimes to.
Ordinarily yes, this is true. However, the greenhouse is far from a sealed enclosure. There would be no chance for the intake and exhaust to create a pressure differential. But for a real building you are correct.
There are gaskets. I just didn't bother replacing them since I didn't have a rebuild kit yet. Next time my heater gets coked up I'll replace the gaskets too.
Change the green fuel line that is supplied with some of these heaters...it is not compatible with the pumps and is not fit for purpose.....it flexes too much and causes air bubbles and diminishes the flow of the fuel due to the minute stroke of the pump....Purchase some `hard` nylon type fuel line ( normally white)...you will have far less problems ...especially at higher output settings.
@alienscientist8893 I didn't really see any obstruction in the exhaust. After this whole exercise the heater was working pretty well. I only use it in the spring to warm up the greenhouse when there's not enough sun yet.
When I clean mine I always use mapp gas and I heat the hell out of it untill all the smoke and black chunks stop coming out of it and that usually is good enough to get the screen out and clean the steel mesh that is behind that screen and wraps all the way around the inside of the burner that you cant see and is usually all plugged with crap too. That is why I torch the living crap out of it to burn all that out of that mesh. th-cam.com/video/QFrWCa7tfM4/w-d-xo.html for reference on the mesh I am talking about.
Why remove the screen? Why not just use your carb or brake cleaner then blow out with compressed air.. from both sides or from it's down stream side out... till clean...?
Thanks for the in-depth repair. Now I don't have any more apprehension with tearing into one! You might get a cleaner burn if you route the intake combustion air tube to the outside of the building. Probably wouldn't do much when you first start as the room air is cold anyway but as the room warms, the unit is suckin in warm air instead of cold, so not quite as good for combustion. It will be even more relevant if you try lesser fuels, then a super clean burn will matter more.
These units are called diesel heaters for a specific reason they run on diesel fuel and kerosene only. Yes you get a bunch of clowns that tell you they will run on just about anything and they will for about 2 days, if you want this thing to run,, use number 1 diesel or kerosene only. Proper installation is a must with these units I see several flaws in yours
That was so painful to watch ...... the removal of the glow plug screen....... a thick bolt with self tapping style thread like a decking bolt and just screw into screen until yo feel it catching and pull bolt out as you still turning it clockwise and the screen will be on the end of the bolt
Holy shit dude! I'm the last to be a safety nazi, I've done plenty of dangerous shit. But man, you lucked out with the brake cleaner. I thought you were doing this outside, then when you started hitting it with the torch, I see you open a door! Just spraying that much methylene chloride, you should have been high as hell. I think they banned it in some country bc a guy died using paint stripper that had methylene chloride in it. General rule of thumb, if it acts like gasoline, but doesn't burn, don't try and burn it! Chlorinated and fluorinated solvents break down with enough heat and make nasty shit like HF, HCl, and phosgene. You seem like a smart dude, but what went through your head thinking its a good idea to pour out large amounts of solvents into a dish in a closed room and then torch it?
When u go to high level you get flame out not that it didn’t sense the fan…your issue is your setting are off the pump if running fast it sounds like Also if the cabin is air tight your causing negative pressure …run the intake to suck outside too
Your mounting method isn't recommended....... They only operate well if mounted level, not turned on its side....... Not a good idea for consistency in how reliable it runs.
@@dogdazetravellergarrett1367 I'm not sure I understand, but do you mean that the exhaust and intake need to be underneath instead of on the side? Can you say why that matters?
@@alaskanhomesteading good morning....... I've owned, operated these heaters for over 8 years now, for full time off grid daily use in winter. Technically, the instructions indicate that you can mount them on it's one side, or the default mounting upright( exhaust and intake ports downside). I've mounted mine like yours in the past, but found that they are more likely to flood, misfire mounted on it's side. I eventually changed mounting orientation to being upright ( flat) default mounting. Just sharing my past personal experiences with this setup. 😎👍
@dogdazetravellergarrett1367 I've seen it can run on its side provided that the glow plug and fuel line face up. (I believe he has it mounted correctly) Even then, they don't work properly? I think it had a lot to do with him running vegetable oil. I was looking to mount one on its side but not sure if I should.
@SqueamishPuppet the vegetable oil experiment was definitely a failure. I should make a small batch of biodiesel some time and try that, just for kicks.
you mix vegetable oil with petrol, not with diesel. It's called a home made bio-diesel Schur mixture (also a bit of 100% alcohol into the pretrol before putting the petrol into the vegetable oil but that is only needed for Diesel engines) The ideal ratio is 5% alcohol (again, only needed for diesel engines, helps with ignition), 10-20% petrol (depending on how cold it gets, the petrol makes it less viscous) and then the rest is vegetable oil. Vegetable oil burns much cleaner than Diesel. Also if you have problems with soot you need to increase the fan speed for any given pump frequency (low: 1.5Hz at 2000-2500RPM, high: 3.6-4.0Hz at 5000RPM) That way it burns more lean which is a much cleaner burn.
@jan_vyhnak I don't have any leaks where diesel is escaping. It could just be that there was left over air in the line from running the tank dry last time.
these use pulse pumps as part of their design.... the fuel is SUPPOSE to gurgle like that. It is not a diesel engine where there is suppose to be no air in line.
FYI, once you start digging that screen out, you've got to replace it. Period. Don't touch it unless you plan to replace it. Also the real problem was the clogged air hole in this case. The amount of carbon in there was literally nothing. He could have simply ran the unit on high for 30 minutes to burn that off. You have carbon problems when that burn chamber is literally filled with carbon buildup and chunks. This guy doesn't know what he's talking about at any stage during this video but at least he kinda said so.
I definitely do not profess to be anything like an expert, or even particularly knowledgeable about these units. I am however thankful for constructive and helpful comments that aid in my learning about them! Appreciate the feedback.
Also, I should add that besides the obstruction in that air hole near the screen, there were also large chunks of hardened carbon inside the base of the combustion chamber. Around 15:30 into the video is where I am working on picking that all out, but I did gloss over that part a bit. The air intake obstruction by the glow plug was certainly not the only issue going on here.
The screens are cheap and there’s no harm in replacing them but…you don’t need to replace the screen unless you severely damage it, I’ve done several rebuilds like this and the screens have the odd little fray, they work just fine. Heat them glowing red hot with a torch and make them round again by pushing them onto a large sized Phillips screwdriver. Then re-install and just make sure none of the screen covers the inlet air hole.
Because they are literally very cheap. Under $200, and made in China. A similar product from Espar or Webasto, at a much higher quality, would be around $1000.
Every four times you start your diesel heater do 50/50 of kerosene with diesel and it will clean your heater out then running mine for 12 years with no problems
Oil pump needs to b at 45 degree angle or it will fail every time plus u need to turn MHz down for pump. Keep an eye on the heat oil will burn almost twice as hot as diesel.
Don't burn brake cleaner. The chemicals can break down to harmful or fatal gases like phosgene or hydrogen chloride
Good advice!! 😬 I had no idea. I've added a note to the video description. Thank you!
@@alaskanhomesteading No problem. I used it a few times while welding, before I learned how bad it is to burn
@@kevinedwards4449 What do you use for cleaning/prep now, instead? I just got an arc welder. All I'm doing so far is making practice beads on junk scrap. (I know not to weld on galvanized metal.)
@@alaskanhomesteadingyou can weld galvanized, you just need to abrade-away the surface coating where the weld bead will go plus a bit beyond.
phosgene is some hardcore death metal shit, seriously. there is video on youtube about leak at a 3M plant once. apparently it can eat through stainless steel braided hose.
Since this video was posted a year ago in 2023, you have probably already solved the problem. I am still learning about these heaters myself. My manual does say that they cannot be .mounted sideways and operate correctly. Due to fuel pooling in the burn chamber. Just something to look at. Thanks for the video on disassembly and cleaning of the heater!
The only way to mount them really is the way they are intended to. That way any loose soot will fall out the exhaust.
I changed all my led screens to the blue screens with the spanner in the top left hand corner and the led remote, which allows access to the special settings menu. The heater ecu also has to be the blue board with the bi metallic silver strip tuning across it, I now burn exclusively kerosene instead of diesel and service the burners every summer cleaning the chambers by filling with oven cleaner leaving to soak for about half an hour then rinsing with water 3 times, this removes any large carbon deposits trapped in the burner. I then blow the burner dry with a heat gun and resemble.
Ok, there's a number of things not ideal in your setup. The fuel filter is the wrong way round and should be close to upright below the pump to eliminate air bubbles and give the pump an easier ride - it will be quieter too.
Also check the voltage drop from your battery on startup, if it is dropping below 12v then your glow plug isn't getting hot enough to ensure reliable ignition. If you fix all of these things and still have the same problem i suspect that the glow plug mosfet on the control board has begun to fail and isn't allowing enough power through.
I had one to fix last week that was doing the same but didn't respond - turns out the guy had pulled the wiring harness too hard and had broken the copper wire inside the sleeve so that also caused a lack of power to the glow plug.
These are wonderful machines and it pays to have a full kit of spares if you rely on one.
Thanks for the information!
@alaskanhomesteading And if I may add, the controller - mainboard combo you have is a "dumb" type so if you go to ali and get a mainboard, your controller will not work and issue an Error 7. You will have to get a full new pair, these are called "smart" and are compatible with a wide variety of controllers.
On a side note, which elevation are you? 185c chamber temp is too low and should be 200 - 220 nevermind which power setting you have, 1 or 10. This might be fixed by enabling altitude mode ("plateau mode"), search the net for that, it's some hidden menu somewhere. Good luck!
A full kit of parts is more expansive than a new heater. Just buy another heater as spare.
I'm in Newbrunswick, Canada and run a vevor diesel heater to heat my mancave. I find that the filter for the intake that vevor provides is garbage in extreme cold conditions. The filter collects ice crystals in turn, clogging the filter and suffocating the system, causing extreme smoking. I removed the filter and have had no recurring problems. Once and awhile, it is also a good idea to run your heater on high to burn off any soot in the system...
I wonder if I'm having a similar ice crystal issue here at 61.5⁰N!
You’re having incomplete combustion. It’s burning rich leading to the unit coking/sooting and this gets worse over time. You need to introduce more oxygen to burn cleaner and hotter!
Carbon build up reduces heat transfer in the screen, the ignition/burn chambers, and the metal housing. It never gets up to proper operational temperature resulting in a “cold blooded” machine. Just like an internal combustion engine, carbon build up will destroy your machinery eventually. Carbon is a thermal insulator. Many high temperature coatings use ceramic and/or carbon to protect against over heating or melting. Research stochiometric burn ratios if your doubtful.
The fix:
1: Disassemble and clean.
2: Install new burn screen.
3: replace gaskets as needed.
4: Inspect the tiny ignition chamber where the diesel fuel enters. Nearby you’ll see a hole with nothing inside it leading to the ignition chamber. Be sure this hole is NOT obstructed in any way.
Be very careful to completely seat the burn screen all the way down into the ignition bore. Look into the air port (you should not see the screen or any obstruction!!!).
5: Before you install a new burn screen do the following: Drill this hole to a newer larger size. Be sure you do not damage the fuel port, glow plug threading, or screen. Consider drilling another hole 180 degrees apart from the factory air port. The default design and machining from the Chinese factories are very sloppy. These units burn rich straight from the factory because of this lack of attention to the air port in the ignition chamber.
6: Look at your exhaust system. It should dip down at least 1/4” every foot or more aggressive with no traps or dips to allow soot, water, and diesel to drain from the exhaust system. Also the mufflers design is meant to be installed in any orientation. However the original designs told their customers to drill tiny drain holes in the lowest spots to allow drainage. These D2, D3, and D4 designs are of Western origin that had the patents expire. Once that patents expired the Eastern companies copied the Western designs but poorly with out providing proper customer instruction or machinery documentation.
7: Use larger gauge copper multistranded wire/conductor. You need to eliminate or reduce electrical resistance as much as possible. Go with the largest wire gauge you can. 14-10 American Wire Gauge is a good place to start. The longer your wires the larger the gauge you need. Also charge your batteries. If possible add more batteries in parallel to your battery bank. By adding more batteries in parallel you increase the electrical “flow” or capacity. If you run too small a battery bank you’ll lose capacity and then voltage will quickly drop.
Or consider buying a cheap AC to DC wall plug adapter. Look for 12 volts @ 10-30 amps if possible.
8: Look at the glow plug itself. You’ll see the wires loosely wrapped around the ceramic glow plug rod. If possible find high temperature solder around 500 F - 1000 F (or higher if you can) and solder the glow plug wiring to the glow plug rod. This will destroy the clear poly shrink tubing they use as a safety insulator. I use Permatex room temperature vulcanizing (RTV) copper orange. This sealant only protects up to 600 F intermittently. It will last for a year or two before the copper orange RTV breaks down.
9: As others have mentioned, consider using a diesel additive. I use Diesel 911 as it prevents diesel gelling in cold weather, burns hotter, adds lubrication for the needle pump/injector, and it’s cheap per dose. One bottle typically doses 50-500 gallons US depending where you purchase it. It’s typically 16-40 Ounces in a package and you’ll only ever use 1-2 ounces per fill up or less. I dose my 6 gallon tank at 1-12 ounces and I love my results.
10: Inspect your fuel lines! Do NOT use typical orange/green/yellow soft fuel lines. Use the 2mm nylon tubing and 3mm rubber hosing to make connections. If you’re feeling fancy you can run the fuel lines in 2mm copper or titanium. The copper is said to clog because copper and diesel are thought to be incompatible. My copper line has had no issues over 8 years of use. 2mm Titanium is the premium material but it doesn’t bend readily and you must follow strict process to bend it accordingly.
I live at 5280 ft elevation with lower oxygen/air pressure. After I enlarged the factory air port and drilled another one opposite into the ignition chamber my start up and smoke problems are gone!
Thank you for such detailed information. I am going to save this for future procedure when I have to clean my diesel heater.
Hi,I had similar issues, part of the unburnt fuel clean up also involved cleaning ext air intake and choked exhaust, I do realize your very helpful video was cleaning the unit only.
Great video thankyou
In my humble opinion there are too many inconsistencies with the quality of the heaters which can make troubleshooting a little tricky. By that I mean that sometimes you get a good one and other times you get one that doesn't function correctly. I have 3 that look identical, however they do NOT operate at the same level of efficiency.
My 1st unit sooted up after a very short time and began to give errors. I still haven't taken it apart, and I don't remember what temperature it operated at when it actually worked.
The 2nd unit has been running flawlessly now for 60 days of 24/7 use and the internal temperature reads 405°f pretty consistently.
The 3rd unit has worked flawlessly as a backup. However it's internal temperature varies between 325°f and 380°f. The internal temp will rise as you increase the heat settings.
I have only ever run clean diesel or home heating oil.
Great video!
@ 7:05 (& 25:00), there is no gasket between those two pieces?
I buy a diesel additive (i.e. Kleen-flo) and add a capful to every fuel tank. It significantly reduces the smoke at start-up and also reduces the soot and carbon buildup in and around the burn chamber. It is so effective, I can no longer tell what stage my heater is in by watching the exhaust.
I'm glad I came across your comment. I will do this.
I had been wrestling with the same problem for a couple years but finally have it solved. Problem was not enough air getting through the little hole next to the glow plug. After enlarging the hole to 1\8 inch it starts every time.
Wow seriously?!
@@brunoteixeira6408 Yes, seriously. No white smoke (vapor) since enlarging the hole. Ignites quickly every time. I have 3 heaters and it works on all of them. I'm at 4000' elevation BTW.
You can use other fuels, but only if you adjust the air-fuel ratio properly to match the fuel.
A lot of people are on here trying to use waste motor oil, but not changing the air-fuel ratio, and then showing how much it failed.
In order to change the air-fuel ratio, you have to get into the secret menu, if you're controller will allow it, some don't. In the secret menu you can change the fan speed and fuel pump speed relative to each other. There are people on TH-cam that explain how to do this.
It may not start on the other fuel, so you have to start it and stop it on Diesel or kerosene, or a mix. A lot of people use two tanks and valves for this purpose.
Although it's best to have the inexpensive tools, you can typically get the screen out with a lag bolt.
Using antisieze on either side of the gaskets will help keep them from sticking for next time.
Good luck and have fun with it!
Awesome, thank you for the great tips! I have monkeyed around in some "Secret" menus in the controller, but they were mostly indecipherable. Now that I understand these devices a bit better I'll have to revisit that.
Anti-sieze ! What a great idea !!
I need to service my little 2Kw unit now, same problem, and although I've got the kit coming in the mail with gaskets & stuff, I thought I'd run a thin bead of Permatex Red Gasket Maker silicone ... if I let one side form a skin then I'll add a small amount of anti-sieze grease 😊
Cheers for the video 👍
Old baked on cooking oil residue is best removed with oven cleaner. Carbon buildup responds well to brake cleaner. However, a brush set is a required tool along with a pipe cleaner and toothbrush.
Your problem was trying to burn vegetable oil, doing that blocked up the bleed air hole and it was a downward slope from there. You should run it at full power BEFORE turning it off, not turn it down before turning it off, the more it runs at full power, the less build up you'll get in the burn chamber, that heater was pretty clean other than the starting circuit being gummed up from the veg oil. If you get into the settings, check the max fan speed is 4000 or less, the motor won't last long over 4K rpm, drop the max fuelling a point or two if you reduce the max fan speed to ensure you don't over fuel it. Yes the fuel filter is technically the wrong way round but the mesh is so big that it won't make anydifference, don't worry about the air bubbles in the line, the pump created them, but it keeps pushing fuel in one end si it can only come out the other end, the heater won't suffer for a few bubbles in the line.
Good information, thank you!
On my Vevor heater manual, it says not to mount the heater sideways or upside down. It says with picture diagrams to only mount it straight with exhaust and intake ports pointing down toward floor.
100%agreed
Easy way to remove a stubborn mesh screen. Use a coach screw ( pulls equally on screen )
I have never heard of one of these. Can you post a link to one? Thank you.
Time for the vevor ultra sonic cleaner next 😊
Obviously! I have to get my shop built before I get any more toys. The garage is already overstuffed.
There is also a screen in the other holes you were jamming that tool in, and if you damage that, you will have to replace the whole burner. The best way to clean that screen out is to burn the entire end, and get it red hot. Mine starts up like that too, and usually after I haven't used it consistently. It usually always starts, after the second attempt. I've had it apart several times and still can't figure out why. It has always come apart clean tho with very little soot, and for the most part it is on low, with an occasional high run to warm things up quickly. (I live in Western Wa State.) If you coat the gaskets with graphite, they come off without damage every time. I've had my 2k for about three years and I love it but I can't run it unless it is below 40f.
You might want to try Easy Off Heavy Duty oven cleaner for cleaning your parts if you aren't in a rush. Spray it on and in, and walk away for an hour or two. Wipe it off, or give it a rinse. Much easier.
That’s better made than I thought. Low expectations.
It's a simple enough design, so making a competent copy isn't that hard. I suspect the biggest quality variability on these cheap units is in the electronic controls and the programming in them. The other stuff is commodity. Cast aluminum, injection molded plastic, and a heating element and temp sensor. It's dead simple stuff.
only thing that's happened to mine is burnt out glow plug, last about a winter season, i just blow through the intake and exhaust with my compressor. great heater for the money £69 when i got mine. i do have to remove the lcd control panel and wrap the screen in a cloth or the cold stops the screen working, but if i for get the cloth or a cold snap drops i have to use a hot air gun to gently heat the screen a minute or two.
Any idea why the glow plug burned out?
@alaskanhomesteading it had over 14 months use. 10 hours a day.
@aeroflopper WOW. That's impressive. Pretty cheap fix. These devices are so simple it's nice to be able to rebuild them after failures like that.
Looking at your fuel line it looks like you are pumping alot of air bubbles to the heater. I suggest you mount it vertically so it will run without air bubbles, lubricate the pump piston better (so it won't prematurely wear out) and run a little quieter.
Good info - Thanks
Glad it was helpful! Do you use a diesel heater?
Nice video.....
Thanks 👍
Nice repair job. Thanks
Greetings from Banchory Scotland.
Looks like your fuel filter is fitted the wrong way. It will still work but makes it difficult to see contamination on filter screen.
Suggest you invest in a water separator fuel filter. Also get a coach screw to make removal of screen easy. It is ok to run heater on its side the way you have it fitted.
I wonder if you can run a cleaner through it, like you'd buy fig a diesel truck etc..
I have one of these in my remodel camper, its so nice!
I have been using a blend of kerosene and some hot shots extreme or stanadyne all season additive. You need to have a 20 to 30 % kerosene to diesel mix. I have been doing this for a number of years and I have found it to be very successful. Also have the correct settings for your altitude. The trick is to have it burn hot at the low speed and not to flood the burner chamber. Understand that they do need some serviceing from time to time usually just replacing the atomizer screen and making sure that your air intake and exhaust are clear. The Espar unit recommends using straight kerosene for 30 minutes and that will help to clear the screen. If you want the altitude settings check out utube.
There’s a hole next to the glow plug this hole blocks up and the heater will fail to start. You can clean that hole out without stripping the heater down or having to remove the glow plug. All you need is to remove the rubber boot on the glow plug hole and with a bent bit of wire locate the hole and poke the wire in it to clear it. Now this is an issue with this design of a heater and they do leak co2 into the hot air out let. The main course of this is exhaust back pressure so if you have a long exhaust run it’s more likely to soot that hole up and the heater will carbon up inside.
very similar to a diesel particulate filter vapouriser. glow plug and a spray of diesel to burn out the soot of the exhaust filter. gets the exhaust up to 600c
FWIW, just from the brief glimpses of your fuel filter, it looks like it's installed backward. The filter will work in either direction but if used in the backward direction, the debris and sediment you are filtering will be collected on the inside of the filter element (the side you can't see) and it defeats the purpose of the clear housing because the filter will always look clean. If I'm wrong, please ignore my comment.
I found a thermostat for these heaters. It will turn the heater on and off not just turn it down. I ordered it yesterday.
Drop a link to what you found. Is it the Afterburner? I've been looking into that one, but neither of the heaters I have are compatible with it. That system requires a very specific control module on the heater. I may resort to buying a compatible module off Aliexpress or something.
You can't use that thermostat the heater needs to cool down before completing it's shutdown you'll damage the heater.
Nope It works just like the key fob. It cycles off@@stoneyswolf
Can you link to the thermostat you're using?
Bureck LLC@@alaskanhomesteading
A lot of people take that screen out, especially if it gets fouled. I have never in three years taken mine out. I have burned it off once in all that time, and it spends most of the time on low. I have a 2k inside a well insulated 8x16 cargo trailer.
Use Kerosene, can mix with veg oil as a mix. Long burn. I used Long nose pliers to get Metal gause out of feed pipe. Better heat from Kerosene.
It also says in the book NOT to mount sideways! Intake and exhaust should be facing down! At least that's what it says in the one I bought!
You are 100%correct. Unit needs to mount right side up. Any suds cabon will gravity falls out of burning chamber. Even installation manual mentioned this
If you ever have to do this again, I would get a gallon of chemtool carb dip and let the burner sit in that overnight before cleaning. As someone else said, you may have dodged a bullet with the brake cleaner this time, but yeah people have died (slowly and painfully) from welding when even small amounts of brake cleaner are present.
Awesome, thank you for the suggestion. I assume this cheap heater will need to be cleaned again, so it's good to have a better/safer product.
Did you consider running a copper or aluminum exhaust pipe line from heater at an angle across a longer space to near the ceiling then exiting building so heat radiation loss is to the inside of building rather lost going directly outside?
@@guestguide2544 I have heard mixed things about that. Some people mention potential issues with excess exhaust back pressure from this. But I've also seen people run the exhaust through an old radiator, soooo.....
HAVE YOU EVER THOUGHT ABOUT WHY THEY DO NOT USE COPPER FOR CAR EXHAUST? The reason is it is against the law in some countries and gives off a poisonous gas at high temperatures.
I know in this case the brake cleaner has had no problem at all breaking down your gunk but for baked on carbon, I have found carb cleaner to be far more effective, brake clean would not touch the crud on my cars intake manifold but it dissolved quickly with carb cleaner.
You done well 🎉🎉🎉🎉🎉😊
Thank you for the video.
Dont forget the magnet on tbe fan needs to contact the bourd so keep the bourd attached
Yes, this heater had some problems with that initially. I had to adjust the fan's position on the motor shaft to make it work more reliably.
Couple of questions though not yet half way through the video. First…can you provide information on these rebuild kits?
And second…would you tell us everything about that snow roof rake!?!?!👍🏻
Here's the rebuild kit I bought.
hwww.amazon.com/gp/product/B0BLG8MXWJ/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1
The roof rake is pretty great. I've used it to clear off my greenhouse and high tunnel when we had excessive snow load.
@@alaskanhomesteading okay…I’m confused. The video you linked is for a hydraulic fluid change of your Branson tractor. And, the snow rake… and name I could research to find one to buy?
I have a Kioti tractor but, I did look at Branson. Our only local dealer was not very convincing of customer service… so I ran like Forrest Gump!
@@keithrayeski6417 LOL. Copy/paste fail on my part. Someone had asked me about a hydraulic filter on another of my videos, and I was copying that link for a reply to him.
I updated my reply to you with the amazon link. I'm not affiliated or anything, but that kit seemed to do the job.
I forget the brand on that snow rake. I got it used off facebook marketplace. The one most people seem to like more is the "avalanche" snow rake, which includes a sheet of plastic that slides under the snow, to help it fall off the roof. With this one, you really have to pull the snow backwards towards you.
Hi I have the same heater but mine after 2.3 hours of operation the fan starts over speeding and fluctuating the speed up and down even the heater has the same speed setting and finally the heater shuts off and my it gives all the smoke from the combustion chamber on the intake pipe and very strangely, no error code. What do you think
I use one for heating my greenhouse i use central heating oil instead of of diesel as it works fine and is a lot cheaper, the only problem i had was with the voltage the battery system went down as i use a charger to keep the battery topped up and i didn’t realise that the charger had gone bad soon sorted with a new one and back to normal .
It sounds like your Fuel Pump is upside down.
The output end of the Pump must be pointing up .
Nice fire proof stand. Work near door for quick getaway
@@robertkincaid9122 correct. I had good rapid egress available and a nearby fire extinguisher.
Well done now i know
Big mistake using a flame with these solvents, certainly asking for trouble. I've plenty of experience in cleaning out soot from Diesel heater steam cleaners, a good wash with alkaline traffic film remover and a pressure washer will remove any debris and it's safe. Dry thoroughly and replace atomiser screen properly so it doesn't block the air intake hole, fit a new glow plug as a matter of routine. Don't mix old veg cooking oil as the flash point is higher and can gum up the atomiser screen. Kerosene is fine but 5% two stoke oil might be a good idea to lubricate the fuel pump or 20% diesel. Have fun
You're 100% right. I made a follow-up video to thus regarding the dangers of those solvents decomposing at high temperature.
Hello if you please can you tell me how much hours work in good situation before maintains and which level from 1 to 10 work good without cock get in ....are you understand me?
@@firashejazi2869 I understand, yes. I don't know the answer as far as hours, but the general guidance seems to be to run at higher levels to avoid coking.
@alaskanhomesteading No i think in level 4 is good for consumption of diesel and 90% burning...if you search on China website they told that. Have a good day
if you increase the voltage to the heater to almost 14 volts, your sooting , and error codes will go away. the higher voltage will make the glo plug hotter. thus burn cleaner, less fuel consumption.
I bet that's part of the problem. The car battery I've been using is quite old and tired, so if I haven't had it hooked up to the charger, it will not perform well.
How I do that
@@Timetraveller1010 you'd really have to connect it to some kind of regulated DC power supply to do that. Car batteries just don't sit at that high of a voltage, even on a battery maintainer.
Code E-10 low Volts.
E2 is low voltage
Never see u fit a new gasket??
if I recall other videos right ... to get the screen out you put a screw into it and pull it out....
I'll have to try that next time. Once I got it out I noticed that it's a little rolled-up length of screen, so it makes sense that you could twist it in a direction that would tighten the roll and shrink its outer diameter, making it easier to remove!
Im curious why you don't just burn propane? I know its more expensive but it emits co2 when you burn propane which would benefit your plants.
@danielcleaver9349 it's a good point. I have in fact been considering either a LP or NG heater for it, but the diesel heater was a fun experiment.
The H2O and CO2 put off by any gas burning appliance would definitely be very nice for the plants!
@@alaskanhomesteading Consider this.
Propane while nice to use, is so danged expensive to use.
About 2-3 weeks ago, I bought one of those torpedo propane heaters to heat the garage.
It worked wonderfully.
BUT, in reading the manual, that heater, on low, would only run for around MAYBE 2 hours on a 20lb tank. Where I now live, filling one of those is around $25 ish. That's just too danged much.
That's why I'm searching for one of these diesel heaters and pretty much, with all the info that I've researched, I'll probably go with the Vevor as well.
I'm just not sure if I want that style or the all-in-one style. I am leaning towards the all-in-one as it's really easy to move around if necessary and not necessarily make a permanent install.
Besides the cost of propane (need bigger tanks, long runs of tubing, etc) for me, there's the issue of having "open flame" inside the garage where there are flammable liquids. Actually, I think that's this is even illegal in my parts. (I should check that out).
Yours is one of the videos that I'm saving in a folder for future reference in case I buy one.
You made it look easy cleaning that chamber.
As for cleaners, I've seen people using *DPF cleaner,* which I understand is specifically designed for diesel engines in that it can literally dissolve all the buildup materials.
You talk about problems with it not picking up the fan spinning yeah there's a magnet on the fan and then there's a little sensor and I had the issue of mine becoming loose on the shaft and sliding forward and then the sensor couldn't pick up that the fan was spinning anymore and was shutting down I slid it back so that it was as close as you can get it without it actually rubbing on sensor and put a clamp on fan so that it wouldn't walk off of shaft anymore and haven't touched it in over 4 years
I had to do the same, minus the clamp. It took a while to get it working after futzing with it quite a bit initially.
How is your pump mounted? It must me vertical not on it's side or low pressure bubbles will rise to the side and wear out the dosing pump..they dose 0.2 mill litres ea pump and the dose will be incorrect..and destroy the pump..
Don't restrict the intake at all and 0 bends in the exhaust..straight down!
You have a combustion issue, back pressure..
Diesel fuel has a smaller molecule even than gasoline and when you mixed vegetable oil with it, It probably gelled and plugged the screen. If you ever want to find a leak in a gas tank, pour some diesel in it and you will find it if it has one. I hear jet fuel or kerosine works well in these heaters. I wouldn't play around with non flammable solvents with flame if I were you.
Do not-Do not-Do not heat break cleaner. Those vapors can be very fatal, very fast. Phosgene gas is the same chemical used in WW1 chemical warfare. Another cheap but flammable cleaner is carburetor cleaner, also found generically at Walmart and is leaves no residue. It is a superb paint gun cleaner also.
Brake cleaner does not leave residue. That's literally the purpose of it. Don't want any contamination left on brake parts! Let any wet cleaner flash off before reassembly and there is no brake cleaner remaining on the surface. If there was any left inside and the heater started up YOU'D KNOW ABOUT IT. Boom!
My unit refused to start after only some 200h. I used it at low power and only pure diesel. How many hours did yours run? And at what setting? Medium/ full power? Or ?
I don't have a count of hours, but it was only at level 4-5 most of the time. 10 is its highest setting. As others have said in the comments, it is apparently important to run them hot to keep them cleaner.
Soak your screen in hopps # 9 rifle bore cleaner as the cleaners design is for breaking loose combustion carbon ( bore carbon )
@@hafsalinda That's brilliant. I have that solvent in great supply. 😀
If you are filtering your fuel and intake air, you should not be getting such a buildup inside the exchanger. Keep things clean (and don't burn anything but diesel in it) and you will be good to go! So many are burning waste oil or veggie oil mixed with kerosene and other kinds of fuel in those heaters and wondering why the buildup? Well, they're not made to burn that crap! It's a diesel heater made to burn diesel.
Do you know why my fuses are always blowing up? I just got mine and it’s never stated because it just blows fuses
My first guess would be that the fuse is undersized for the load required by the glow plug. I've read that they pull about 10 amps, so if your fuse is smaller than that, it won't work. If the fuse is over that size, then I'd be looking closely at the wiring harness for any shorts or damage. If nothing obvious shows up there, then I'd look at the circuit board on the control board, which is pretty easy to pop open. That's the board ON the heater, not the display device with buttons. If something is damaged on the circuit board, it will often be obvious. E.g. charred or discolored components. Failing all of that, I'd take a look at the glow plug. Measure the resistance across the glow plug wires and see what it shows. The resistance should be something like 1 ohm, or maybe a little less. If it shows as a short or open circuit, the glow plug is no good.
That's just how I would start troubleshooting it personally. I haven't experienced this problem.
@@alaskanhomesteading just opened the motherboard came in with a chip split in half. Ahahah I’ll be calling CS
Why is it so dirty? How long has it been running before you cleaned it? Are you filtering your fuel? Just wondering how long I should run mine before I clean it? Thanks for the vid!
I used it for a couple of months, running sporadically. I think the main issue was my failed experiment trying to use some vegetable oil in it, which I definitely do not recommend!
air intake for combustion should always be outside with the exhaust. Heaters dont like pressure differences and there can be smoke from the intake sometimes to.
Ordinarily yes, this is true. However, the greenhouse is far from a sealed enclosure. There would be no chance for the intake and exhaust to create a pressure differential. But for a real building you are correct.
I'm no expert but it looked to me that the fuel filter is fitted the wrong way
Ha! I didn't even notice.
Add a pint rubbing alcohol to 5 gallons of fuel to help keep burn chamber cleaner ..
ultrasonic cleaner would have ripped off every bit of stuff what was inside that filter
No gaskets🤔🤔🤔
There are gaskets. I just didn't bother replacing them since I didn't have a rebuild kit yet. Next time my heater gets coked up I'll replace the gaskets too.
Change the green fuel line that is supplied with some of these heaters...it is not compatible with the pumps and is not fit for purpose.....it flexes too much and causes air bubbles and diminishes the flow of the fuel due to the minute stroke of the pump....Purchase some `hard` nylon type fuel line ( normally white)...you will have far less problems ...especially at higher output settings.
Hey I bet the exhaust is also full of soot..
@alienscientist8893 I didn't really see any obstruction in the exhaust. After this whole exercise the heater was working pretty well. I only use it in the spring to warm up the greenhouse when there's not enough sun yet.
Replace that green fuel line with a hard nylon fuel line .
What's the correct I.D. for that fuel line?
Instead of brakeclean, I suggest throttle body cleaner. I find it just disolves carbon.
When I clean mine I always use mapp gas and I heat the hell out of it untill all the smoke and black chunks stop coming out of it and that usually is good enough to get the screen out and clean the steel mesh that is behind that screen and wraps all the way around the inside of the burner that you cant see and is usually all plugged with crap too. That is why I torch the living crap out of it to burn all that out of that mesh. th-cam.com/video/QFrWCa7tfM4/w-d-xo.html for reference on the mesh I am talking about.
Heating oil works great in these and is cheaper. No off road diesel in alaska.
I can get Diesel at Freddy's for $1/gal off with points. I can't touch that price on fuel oil anywhere.
Why remove the screen? Why not just use your carb or brake cleaner then blow out with compressed air.. from both sides or from it's down stream side out... till clean...?
@abelincoln3261 it was just far to caked up with carbon for that to be effective.
Thanks for the in-depth repair. Now I don't have any more apprehension with tearing into one! You might get a cleaner burn if you route the intake combustion air tube to the outside of the building. Probably wouldn't do much when you first start as the room air is cold anyway but as the room warms, the unit is suckin in warm air instead of cold, so not quite as good for combustion. It will be even more relevant if you try lesser fuels, then a super clean burn will matter more.
These units are called diesel heaters for a specific reason they run on diesel fuel and kerosene only. Yes you get a bunch of clowns that tell you they will run on just about anything and they will for about 2 days, if you want this thing to run,, use number 1 diesel or kerosene only. Proper installation is a must with these units I see several flaws in yours
The machine starts at list when is at 12 degrees ....
Put it in high altitude mode,it will work like a champ,and you will get 30 plus hours out of a gallon of diesel
Pump is not set up correct also after a night on low blast it for 5 to 10 mins to clear it out before stopping it
Say more about the pump setup problem. Your advice about running on high to clear it up after running on low overnight sounds very solid.
Amazon will ship them here just not that brand
Good to know. I was looking for a while and didn't see any that they would ship here. Maybe it changed in the last year?
That was so painful to watch ...... the removal of the glow plug screen....... a thick bolt with self tapping style thread like a decking bolt and just screw into screen until yo feel it catching and pull bolt out as you still turning it clockwise and the screen will be on the end of the bolt
Get yourself some welders needle files
Holy shit dude! I'm the last to be a safety nazi, I've done plenty of dangerous shit. But man, you lucked out with the brake cleaner. I thought you were doing this outside, then when you started hitting it with the torch, I see you open a door! Just spraying that much methylene chloride, you should have been high as hell. I think they banned it in some country bc a guy died using paint stripper that had methylene chloride in it. General rule of thumb, if it acts like gasoline, but doesn't burn, don't try and burn it! Chlorinated and fluorinated solvents break down with enough heat and make nasty shit like HF, HCl, and phosgene. You seem like a smart dude, but what went through your head thinking its a good idea to pour out large amounts of solvents into a dish in a closed room and then torch it?
Lapse in judgment. I did a follow-up video to this one about it.
@@GMCLabs you know what gets rid o carbon? Water let it sit in it for a day
When u go to high level you get flame out not that it didn’t sense the fan…your issue is your setting are off the pump if running fast it sounds like
Also if the cabin is air tight your causing negative pressure …run the intake to suck outside too
The greenhouse is definitely not airtight. 😀 I'm going to have to look into the secret menus and see about setting changes this spring.
Your mounting method isn't recommended....... They only operate well if mounted level, not turned on its side....... Not a good idea for consistency in how reliable it runs.
@@dogdazetravellergarrett1367 I'm not sure I understand, but do you mean that the exhaust and intake need to be underneath instead of on the side?
Can you say why that matters?
@@alaskanhomesteading good morning....... I've owned, operated these heaters for over 8 years now, for full time off grid daily use in winter. Technically, the instructions indicate that you can mount them on it's one side, or the default mounting upright( exhaust and intake ports downside). I've mounted mine like yours in the past, but found that they are more likely to flood, misfire mounted on it's side. I eventually changed mounting orientation to being upright ( flat) default mounting.
Just sharing my past personal experiences with this setup.
😎👍
@@dogdazetravellergarrett1367 thank you. This is the first of these devices I've messed with, so I appreciate the advice!
@dogdazetravellergarrett1367 I've seen it can run on its side provided that the glow plug and fuel line face up. (I believe he has it mounted correctly) Even then, they don't work properly? I think it had a lot to do with him running vegetable oil. I was looking to mount one on its side but not sure if I should.
@SqueamishPuppet the vegetable oil experiment was definitely a failure. I should make a small batch of biodiesel some time and try that, just for kicks.
you mix vegetable oil with petrol, not with diesel.
It's called a home made bio-diesel Schur mixture (also a bit of 100% alcohol into the pretrol before putting the petrol into the vegetable oil but that is only needed for Diesel engines)
The ideal ratio is 5% alcohol (again, only needed for diesel engines, helps with ignition), 10-20% petrol (depending on how cold it gets, the petrol makes it less viscous) and then the rest is vegetable oil. Vegetable oil burns much cleaner than Diesel.
Also if you have problems with soot you need to increase the fan speed for any given pump frequency (low: 1.5Hz at 2000-2500RPM, high: 3.6-4.0Hz at 5000RPM)
That way it burns more lean which is a much cleaner burn.
@swunt10 thanks for the great information!
Try burning jp - 2, 3, or 4 kerosene used in jet engines as a stripper to the combustion chamber.
Air is getting in from that crappy fuel filter
I'll have to look into a replacement for that. I only set this thing up with the "stock" parts it came with. Will any old inline fuel filter work?
@@alaskanhomesteading if air is going in diesel is going out - which i believe is not your case.
@jan_vyhnak I don't have any leaks where diesel is escaping. It could just be that there was left over air in the line from running the tank dry last time.
@@alaskanhomesteading then its just vapor bubbles no need to worry in my opinion
these use pulse pumps as part of their design.... the fuel is SUPPOSE to gurgle like that. It is not a diesel engine where there is suppose to be no air in line.
You didn't watch the video of how to remove screen properly
Nope!
FYI, once you start digging that screen out, you've got to replace it. Period. Don't touch it unless you plan to replace it. Also the real problem was the clogged air hole in this case. The amount of carbon in there was literally nothing. He could have simply ran the unit on high for 30 minutes to burn that off. You have carbon problems when that burn chamber is literally filled with carbon buildup and chunks. This guy doesn't know what he's talking about at any stage during this video but at least he kinda said so.
I definitely do not profess to be anything like an expert, or even particularly knowledgeable about these units. I am however thankful for constructive and helpful comments that aid in my learning about them! Appreciate the feedback.
Also, I should add that besides the obstruction in that air hole near the screen, there were also large chunks of hardened carbon inside the base of the combustion chamber. Around 15:30 into the video is where I am working on picking that all out, but I did gloss over that part a bit. The air intake obstruction by the glow plug was certainly not the only issue going on here.
The screens are cheap and there’s no harm in replacing them but…you don’t need to replace the screen unless you severely damage it, I’ve done several rebuilds like this and the screens have the odd little fray, they work just fine. Heat them glowing red hot with a torch and make them round again by pushing them onto a large sized Phillips screwdriver. Then re-install and just make sure none of the screen covers the inlet air hole.
Why are you ALL referring to this item as a " CHEAP CHINESE HEATER " you bought it !!!
Because they are literally very cheap. Under $200, and made in China.
A similar product from Espar or Webasto, at a much higher quality, would be around $1000.
Every four times you start your diesel heater do 50/50 of kerosene with diesel and it will clean your heater out then running mine for 12 years with no problems
That's great. I'll have to try a mix and see how it goes. Kerosene is wildly expensive here though!
Oil pump needs to b at 45 degree angle or it will fail every time plus u need to turn MHz down for pump. Keep an eye on the heat oil will burn almost twice as hot as diesel.
I had the pump at a 45 before. I must have moved it while I was disassembling the setup. Thank you for the reminder!
That screen maybe your atomizer not to play with it
9/10’s of your problems are from your heater being mounted on its side.
Soak in sea foam, let it do the carbon dissolving.
To cold.
Another typical non tuneable heater sooting up.
Autoterm is a better heater
Way WAYYYY over priced!
your burning out the carbon in the bottom of the chamber
