Just thank you... -33 Celsius in Winnipeg Canada tonight, if it wasn't for your video I would have rented a hotel tonight. I cleaned out the carbon and just reinstalled the heater. Current temp in my bus at install 0 degrees. Heater is blowin hot. I owe you a pint...or ten. Thanks again & cheers

maybe a video how to on controller settings especially for fuel setting 👌😊

THANK YOU for posting this. Have a very similar German made heater in my mobile crane cab. Cold snap coming this week, and I really needed to get it working. Drained diesel, cleaned the line and filter, still no heat just smoke. This video finally helped me figure out what needed to be done. Took it apart and cleaned it up good this evening, and I have heat just in time for an icy work week!

Great video! First time I understood that the reason for the white smoke is that the flame did not start and the fuel is only grilled by the glow plug, due to the blocked little hole, which causes that there is no ignition flame and no real burning of the diesel

Well, I tore my heater apart three times before finding your video I saw 2 years ago. I had the white smoke out of the exhaust and intake. Cleaned it 3 times, more places each time, the fourth time I went directly after that little 1/8th inch ish hole by the screen, cleaned that out with carb cleaner and it fired right up. Thanks for the video, I now have a backup heater again.

Thank you sooooo much. Mine was smokey too, but after watching your video and removing a cup of carbon she now runs like a gem 🤙

Had the exact same issues, followed up his video and now works perfect! If you ever do a video with the recommended settings on your controller it would be very much appreciated 😅

I have tried for 2 weeks to get my heater working and no-one could give me advise to fix it but I then saw the title of this video was my problem so watched it and no-one had mentioned the little vent hole in the glow pin hole to me. I removed the glow pin, found and cleaned out the little hole and away it went. Thank you.

Absolute brilliant video, what would we do without people like you sharing stuff on you tube, thanks

Thank you David, I bought a Parking Heater in January this year and I'm very pleased with it. BUT! I've read so many bad comments about these CDH . Your video is very reassuring that these heaters can be easily repaired.

Another thank you my bunk heater quit last year it would come on click click shut off white smoke. After watching your video took it upon myself to pull it out and see if I could find the issue. It was easy got it apart that plug hole on the side you was talking about was my issue I cleaned it out, Clean the glow plug tip put it together and it fired right up. Shut it off several times to see if it continue to work and it does hot hot hot thank you so much again for your video.

im now having similar issues with mine but your video has helped my knowledge to whats inside and how to strip and rebuild it, plus your handy tip if the small air hole at the glow plug. thank you.

Thank you for making this video. My “new” heater instantly started to act like this and your information helped me repair it. Turns out they sent me one that was FULL of debris and gunk, probably just gave me someone else’s return. SMH. You’re a lifesaver!!

Thank you for the video! I would have never known that little air hole was there, I took out my glow plug and sure enough, it was plugged up. I removed the screen also, but that seemed ok. I've been pretty good with running mine at full blast every few days to help keep the burn chamber somewhat clean. Cheers!

Thank you so much for posting this video mine was chock-a-block with dust and now working perfectly thank you.. I have ordered a clean as snorkel intake for it

Billy Connolly does night heaters !! Great videos though I have to say. Ive had a few issues myself with carbon build up . I've found there is usually some other problem that leads to premature carbon build up like low power due to battery voltage being low in first place and further volts drop through over length wiring of wrong section cable or incorrect plumbing allowing air to hide in joints , filters and pumps . Brilliant heaters when installed and used correctly though .

Love this vid. I purchased a diesel heater that has yet to arrive and was wondering how user friendly they were to take apart and service. I built my own waste oil heater for my shop out of scrap over a decade ago. These are not real complicated. I think I will be happy with mine.

So... White smoke, no light, check hole. Nice video, I understand my Chinese diesel heater much better now. Thanks for making it.

Thank you for the great video's I am going through them as I get time just wanted to mention something about my own experience with one of the heater's that also got full of soot after only 3 days I cleaned it and ran at full power for 4 days and it stopped working I striped it down again and cleaned as full of soot but this time I noticed my fan had 2 magnet's on it so I changed the setting SN1 to SN2 and now it runs great ... It seems the brain thought the fan was going faster than it was and delivering to much fuel , hope this helps someone,keep up the great work. HAPPY NEW YEAR 🥳

brilliant mate. having a bit of trouble with mine so you have given me some starting points to have a go at fixing it😁👍

I had the same thing when the exhaust run on my heater in the garage was too long. Exhaust blocked and the heater got flooded. Unblocked exhaust, still a smoke machine. Figured the fuel air mix was off so I let it try to start and blew down the intake as hard as I could. Smoke, Smoke, smoke, POP! whooosh. Let it run as hot as possible and it was fine. It only took about 2 days for the smell of Diesel fog to dissipate....

Thanks for good video. I bought one after seeing one of your videos.i have had it in my van now for over 24 months. With no problem. Thanks 😊 its a god send and for the 130 pounds I spent worth it.top branded ones are 500 plus. I even put it on when at home.why because I didn't want to de ice my windows in the morning. On a low tick over at 16 degrees. No ice and van starts 1st time.such a low battery drawer when at temperature .I thank you kind sir lol

Luv wacthing you work your magic I need a man like you... another great video!! Thanks, I'm about to buy one for my boat, going to tap into my diesel fuel line instead of using a provided fuel tank...

Thank you!! I was about to order a new one and drive 300 miles to the nearest shipping location

MY HEATER HAD LESS THAN 1 GALLON BURNED THROUGH IT ,AND I REMOVED THE GLOW PLUG AND STUCK AN L SHAPED PIECE OF WIRE THROUGH THE AIR HOLE AND CLEANED IT OUT, AND IT FIRED RIGHT UP, THANKS FOR THE INFORMATION!

Thank you. I've been wondering what goes on inside, it's basically a mini "salamander heater" we call it. Like a big orange job site heater with k1 in a tank on the bottom. It's like that but inside its own own heat exchanger. Brilliant

David, Also worth getting the burn chamber REALLY clean and bone dry by heating it up with a blow torch. Once cool, reassemble. Its amazing the clouds of smoke you'll get from very back of chamber with a blow torch (where its almost impossible to clean) and it gives an even greater chance of a successful start up. From what I've gleaned, the hidden part of the burn chamber is composed of a ring of welding blanket (carbon felt) which can absorb fuel like a wick. Its held in place with stainless steel mesh. After running rich or flooding, this felt no longer soaks up diesel because its become totally gummed up with soot and residue. It sets like concrete in there and the fuel can't catch fire and invariably drips out the exhaust or air inlet. Carb cleaner (or cellulose thinners) will definitely aid cleaning the burn chamber but the blowtorch is the surest way of restoring the absorbency of the carbon felt, and its super fast. You usually get flame out or E8 error after the white smoke which is often attributed to fuel when sometimes what it needs is a proper clean - and/or as in this case, clearing of blocked holes.

Came here because my heater on my Merc w211 had suddenly stopped working after we started having temperatures below 0 degrees Celsius. Fortunately I figured out the issue today and boy was it foolish. The exhaust pipe had shifted off from it's hole on the bumper and its end was surrounded with 1 cm thick ice. After tearing it off and blow torching the ice off from the tube the Eberspächer started right up, but it smoked like hell for 15 minutes meaning the entire hood area was full of smoke including some smoke on the interior as well. To help others here were my symptoms: Heater fan and glow plug started normally via remote. After 30 seconds of running the diesel pump started clicking slowly. After 1.5 minutes the diesel pump and the fan gradually went crazy to the point where the clicking was really fast and the fan was super loud. After 2.5 minutes it just shut off the diesel pump and the fan started running low and quiet. If you are experiencing same type of behaving with your heater I'd recommend you to check out the exhaust pipe from both ends.

Great video mate. A massive help to me in sorting my E10 error code. Thanks a lot.

Great video got the same problem with the heater on my truck at least I now know what's causing the problem so be stripping mine down in morning

Hi David great video ours ran for 1/2 he then started blowing smoke error 09 ,so I will have look inside as you have thanks again rgds Peter

From my experience from same heater, if I use maximum pump speed, 5,4Hz it start sooting and after a while barely give any warm. And it would not start, only white smoke. If pump settings are 5.2Hz or lower then it goes on without problem. I think it does not got enough air to burner. Maybe fan speed tinkerin can help but some said that bearings will worn out quite fast if run 5000 rpm

Yet another brilliant video 😁😁👍🏻👍🏻

Can you please explain the changes to the settings to reduce the fuel

This helped me loads, thanks for the video! My hole was blocked too

Do you have a suggestion for duty cycle or minimum on time? I have heard these need to run on high all the time. Trying to decide on a cheap 8kw or cheap 2kw. Great videos, learning tons, cheers!

nicely done .. that really was letting out the smoke

Great job thanks and cheers from Canada.

My mate adds some injector cleaner in his diesel heater and it cleaned it out well, no longer blows white smoke now 👍

Got me out of a right pickle this tutorial, thanks alot mate. 👍

hi dave nice video learned a lot, can you tell me a good company to get a heater for my ducato van cheers john

Great video, thank you for sharing your knowledge.

Thanks very helpful now we know what makes it glow 👍👨🏻‍🏭

brilliant ... thx ... fixed my issue ... blocked flame hole

how do I know with my heater which side i can lay it on without opening it up.. the install book for my coolant heater shows all kinds of different appeciable positions.. I have issues when it is -5c or colder with it doing white smoke starts.. after about 2 or 3 tries it will fire up and run normally..

Hey dave I run a air intake filter so nothing gets sucked up I opened a heater and found a Wasp nest , Rob NSW Australia

Mine does that exact same thing...except mine always starts up immediately when I wait about 15 minutes and try to start it up again ! I tore it apart last week to see if I could see anything wrong... it was Super clean everywhere inside of the unit (I have used it for nearly 3 years and first time taking it apart) ! I am now guessing it must be my Glow Plug ! (I should have replaced it when I had it apart and out of my van !)

I am in the market for one of these is there a particular one that you prefer or are they all the same

I have 2 of them. Found out old fuel will clog it up quickly and make a lot of smoke. Also saw one guy who said always having it on low will produce a lot of carbon deposits in the burn chamber. Hard to find parts. But it kind of looks like they are mostly the same internally.

Any idea why my glow plug stays on constantly? The display shows the glowplug is on all the time? Many thanks

Ever try shooting in a good blast of brakleen into the intake while it is running to de-carbonize? Just wondering if it would actually work or not.

Flagpoles from amazon maybe ebay duno but I got these out of a "return bin" and they work SUPER for ex pipe!. I put them on my van and in garage! Fits perfect onto the ex of unit, sections of bout .5 meter then the top where the ball is fit PERFECTLY on the outside of a muffler! (with two little half holes who cares!) I got all of em I could and my cats Hungry.... TBC...

Thanks for the great informational videos on the heaters. The burner tube on my no name "8kw" Chinese heater screws apart so you can remove and clean the metal wool and screen sleeve in the base (not referring to the little diffuser screen around the glow plug). All the others I've seen are one piece or welded. Any idea where I can get a spare metal wool sleeve?

A 5kw heater I've been using for a couple years began smoking on startup but always started on it's automatic second try. Internal inspection showed no carbon buildup, mesh was clean, and the small hole by the glow plug was unobstructed. The motherboard was the problem. Replacing it fixed the smoke issue.

Awesome info, Helloooo from the USA

Hi. When ya say you altered the controls. What did you actually set the hz and fan peed to.

If you run kerosene or even better the synthetic version every once in awhile, you’ll never have to open it up to clean it. A few capfuls of Automatic Transmission fluid in every tankful will make a world of difference

I shared your video link on my video about these diesel air heaters about not running them on low all the time because they will soot up

So. I just faced down my demonic smoke belcher and might have been victorious. I blew in the intake as somebody mentioned, not plugged solid. Had already replaced glow screen and the plug today as it was damaged from overheating itself. Blasted a bunch of electronics cleaner in the glow hole followed by compressed air previously. Shot it with more tonight, rammed the plug in and set it to go. Sprayed carb cleaner up the intake a few times and got nice fireballs a few times. Noted chunks of cokey soot rattling out the exhaust. Got nicely heated up and seemed to quit smoking so bad. I had left the shroud off and it went E05 overheat which may have further contributed to self cleaning. Now its actually heating up again and all but zero smoke.... wow.

Hi. Thanks! Do you know why the fuel pump needs to be at this 45 deg. Upward angle. I've been running mine 45 deg. Down hill. Thanks! Love the vid

I currently only have a heater that will start when I add brake clean to the air intake on start up. Also running 30 70 mix of hydraulic oil and diesel which may also be the culprit

my coment befor watching im in a van at the moment and have this problem I spray egr up the intake whistle tryingto start and it pops then a quik flame frows sutty gunk out then it starts after a fuw times.a pump or cloged exorst also causes it .

As usual a great video

Helloooo David Have you had any dealings with the Webasto type water heaters like the ones used as pre heaters on diesel cars, your videos on the air heaters are brilliant as you put it all into simple terms for the average bod out there (webasto vids would be good) Cheers Grahame

Hi David I keep getting e05 on my heater second unit that I've had could it be my main board as air flow is all good love the videos thanks Ry

Do you think it would be possible to clean the heater by squirting brake cleaner through the tiny hole near the glow plug before it finally gives up starting ? Great videos thanks.

Hi David, is the air inlet hole near the glow plug accessible for cleaning without dismantling the combustion chamber. I was wondering if by removing the glow plug and using a right angled probe to dislodge any built up grime in the air hole would work ?

Hi, what settings on fuel did you use?

Hello, the video you shared is very explanatory , I have some questions, how is a metering diesel fuel pump cataloged, by pulses per second, pulses per minute, I saw a diesel fuel metering pump and it says 22ml? Thank you

Hi! Love your video's my man. It takes some effort to make out the dialect :), but thats ok. Did you already experiment with a catalyst in the exhaust?

Fantastic video

pulled mine down , all the screws where loose inner and out ,had 500 liters of fuel threw it . so put it in the ultrasonic cleaner , put it back together with the old gaskets and permatex gasket goo, woks better than new , just wish i had of done that before i put the 2nd one in . the burn chamber an glow plugs where hand tight so was the head .

Hi David love the videos , here's a good one for you , I have a Chinese 5 kw 2 months old 300 hours use now , past few weeks seems slower to light and smoke for few minutes then lights ,now the mystery is I can smell the grey smoke coming out of the blower vents , I've checked its not from the very end of exhaust outside ,I looked underneath and its leaking right near were it joins the base / manifold outlet ,I've re done the exhaust nice strong super clamp even a wee bit of paste ,but it still puffs out a tricle of grey diesel smoke which is pulled into the gap were the silicone gasket is ,the silicone gasket is also brittle and broken only 2 months old !, any ideas were this smoke could be coming from ? I re tight end exhaust clamps 3 times to check ,it wasn't them it seems nearer the very base of the alloy exhaust pipe ,can they crack ? Its bizarre,and dangerous suppose not using it obviously till fixed , I can not see any cracks in the exhaust port ,the clamp was tight on the exhaust tube no play , I think its been doing this a while but I only can smell and see it when its starting up, Starts up .. glow plug on ,pump on ,then grey smoke then maybe 2 minutes it fires up and runs ok , the smell goes away from blower vents but I guess it could still be emitting invisible gases once its running warm , any ideas I remain baffled 😀

I have a D1LC and a D1LCC, The D1LCC had a fan with worn out bearings so had a noisy fan and I think it overheated as it currently does nothing when switched on so I think the ECU has locked out. Ordered a 801 controller to diagnose it/unlock the ECU. The D1LC has a good fan, starts up has a lot of white smoke. I swapped the burn chamber/heat exchanger over and it wouldn't pump fuel. I swapped the flame sensor over and it fires but doesn't produce hot air but the exhaust gets hot and the pump and fan are running at max. Tried running on paraffin and old white diesel. during shutdown when the pump stopped and the fan speed reduced slightly hot air started being produced. It's as it the fan is cooling the heat exchanger to much. The D1LC doesn't have a magnet/hall effect sensor so the ECU doesn't seem to have a way of monitoring the fan speed. Shame it doesn't work as I want to stop using my calor gas heater in my 20ft container workshop as refill prices are getting silly.

16:10 “white smoke, no light, check hole” - that should maybe go on a T-Shirt?

Hi David, Ive got a heater with the water heat exchanger built in, from Alibaba, works great, but im wondering if its possible to fit a controller from one that doesnt have the water pump control built in, as id rather control this exterally, and the controller it came with isnt the best with chinese writing etc.

Good job mate. From Australia 🦘

Hi it's me again well this has got me stumped took the fuel filter off and still the same results still smokey on start up put the fuel ratio up and down still the same results now the heater sounds like a digerydoo on tickeover cleaned the plug and hole n new mesh.. it's ok on flat out but echos through the whole van on low time for a stripdown ? Thank you for all your videos nice to watch someone after my own heart love the content

At the start of the video you said that the person that sent the heater to you claimed it was new and it had never run …???.. clearly it was a very well used heater being operated by somebody who had no idea what they where doing with the settings for the burn control causing this problem of over fuelling the combustion chamber . Apart from that what a great video for all those do it your selfies .. nice job .. 😊

Many thanks for the tips. Is there a good source of the burn tubes? And other spare parts like gasket sets.

did you say at the begining that the user said it never worked?or did i missunderstand...anyway it looks like it worked alot...thanks for the great videos.....

I've been pouring liquid oven cleaner into the burned and it sure cleans up very well. Is there any reason not to do this. I'm also using carburettor cleaner aerosol.

If you remove the glow plug , and use brake cleaner, and carburetor cleaner with straw sometimes will clean up enough to get it hot . The carbon is acting like a space shuttle heat tile. Due to faulty controller shutdown developed this carbon condition And thank you autozone

I had similar malfunction after burning 300 liters of diesel, I'm cleaning it every 1,5 months, but this time she (it's a girl) didn't fire up, white smoke, cars stopped to see what's going on, as smoke poured out of my cellar (use it for home heating) Opening up that little 3mm hole near the glow plug made all the difference, as I didn't clean it before, she started right up after cleaning.

if you put the exhaust paste , away from the edge of the outlet pipe , you avoid any paste being scraped into the exhaust , causing an obstructing , i think thats what happened here.

Did you replace the internal gasket as well? If so, was the old one cracked or anything? Thanks for the vid.

Unfortunately I think I'm going to have to do this full diagnostic... I'm having a similar issue although mine ran for months before I had problems. I have found a lot of carbon build up inside the exhaust pipe... When it was burning fine, I didn't notice any smoke at all... So I'm not sure why it is burning so poorly. When its on full blast the internal combustion chamber gets nice and hot, between 170-210 Celsius... I'm only at 1300 m elevation. My controller doesn't allow me to change the hz... I either can have it on the standard settings, or change it to alpine mode for 1500m+. Since I'm below 1500M I haven't ever run it on alpine mode... Once last week, it smoked everything up and then got E8. Cleaned out the exhaust by wacking the metal pipe against the ground, and used a tooth brush to attempt to get stuff out of the muffler... Got it running really hot again and it was fine, until today. Now I think I need to pull the entire thing apart and clean everything out...

Pan down for the "Safety Crocs" . . . . By the way what Bench Power Supply you got. . . ? I was stoked when you explained the "vent hole up" . . . I want to rotate my tower unit so as the exhaust comes out the side.

I’m getting a weird white solid build up in the combustion chamber and white smoke pouring out the exhaust. I’ve stripped and rebuilt and it works every time for about 2 week before the same build up comes back. Run on red and white diesel with no additives. Only other time I’ve seen build up like it was with a blocked dpf on a car. Exhaust doesn’t seem to be restricted at all. Any ideas?

I had problems with my diesel heater and I thought it was a faulty fuel pump so I installed a new pump, after all they are cheap on ebay.... but my problem turned out to be the silly little hose clips letting air into the suction line from the fuel tank. I fixed the air leaking hose and the heater worked great for its test, but on holidays using it, it started smoking and got so bad it could not be used. Once home I removed the heater and got a repair kit I did not need....and pulled the heater apart and got maybe a cup full of oily soot from its insides.....I had been running it on low mostly so concluded it should be put on high every now and again to burn itself clean.... That is when I watched a video on just how the fuel pump size controls the air fuel mixture....and sure enough I had installed a larger pump..... I installed my original pump and were thinking I might have to pull the heater out again to clear the soot build up when I got the idea of using a 12v matteress inflatar to blow extra air into the heater combustion air intake and see if it could burn it clean, and it worked a treat....with the heater thermostat set to maximum I removed the combustion air intake filter and blew the extra air in.....and it roared and smoked like crazy but heated up and burnt itself clean..... It has been working like new again and had hours of use since.... So don't try using anything but air to feed the combustion air supply, if the heater is smoking. Of course this is no substitute for someone that knows what they are doing programming the air fuel mix in the advanced program settings of the thermostat.

Excellent thanks for this

Brilliant Video thanks

i was testing mine last night for couple hrs outside and it was upside down and seemed to run fine with no leak? you would think they would have a This side up sticker on it ?

David, could you soak it to clean it? If so with what?

My one drips oil from the intake but only when it is run on a mixture of engine oil and diesel, doesn't do it when run on strait diesel, any suggestions on what may be going on, it is a new heater with the new controller like the black one in this video only it has a spanner emblem where the others have a asterisk, none of the codes work only 1234 and it gives you some strange settings.

Hi I get the same thing but when I start it on second attempt I get it to fire up it seems.like the first start blows the flame out when the glow plug light goes off. Any advise

Good work

Had a similar thing happen to mine kept getting EO 8 then EO10 took the exhaust pipe off because it was running OK just fitted the exhaust with paste (whoops bit too much blocked the exhaust), cleaned the exhaust then tried again with an air pump on the inlet just for a few seconds then it fired up been running OK now turned it down to 3,4 ghz. So warning do not use too much exhaust paste.

Three years of use on my Espar D2, and only a light ash coat inside.

HELLOOOOOO! My Vavoer "8K" is a year old. Now throws ERROR 10, smokes like a Cummins, refuses to ignite. Replaced glow plug, same. Took it apart, was super clean inside, except a hard grey ash way down in the bottom of the burn chamber. Picked and 3 tbsp. of that out, looks clean as a whistle now. Soaked in a good carb cleaner, allowed to fully dry, reassembled. Still no joy. Am thinking that the catalyst screen in the burn chamber must be gone or ruined - everything else checks out right as rain. Your thoughts, please?
