- I bought a diesel heater and installed it in the workshop.
The day after I released the video about it, it failed.
This video is about the problems with the unit, and the solutions to those problems.

Hey bought one to for my little man cave. I followed everything from your idea . Everything works great. Thank you very much. Sir. Hey UA-cam we need more people like him or her. Take my friend from Ontario Canada 🇨🇦.
Yes, many of us owe a debt to John McK 47 for his very thorough descriptions and explanations of the why and how of the elements of the systems. Beyond simply listing solutions, he teaches a 'systems approach' to understanding the machine and the physical principles. Of the first class UA-cam content creators, the teachers are some of the best.
Hi Pete, absolutely. 👍
Excellent video, thanks. The reason the tank outlet is not at the bottom of the tank is to allow sediment or debris to settle without being sucked out and into the engine.
As some people already explained, the pump has to be in an angle. Also not upside down because air can now be trapped.
The outlet of the tank always must be a bit above the bottom for water and debris to settle.
Most cars and trucks gas tanks, have some safety space from the bottom to the inlet, so gunk, gel, and water can accumulate and be spotted on the bottom, before it reaches the sensitive systems.
And a drain plug at the very bottom, to get rid of those accumulations.
Thanks for your video!! Kudos for a Very neat and clean workshop!!
Very informative video and your timing is perfect as I am starting to look into this as an alternative to expensive fan heaters. As I think others have mentioned the tank outlet is to allow debris to settle in the bottom of the tank and not get sucked into the pump. Car fuel tanks work in exactly the same way.
You have a new subscriber. 🙂
Hi Andy, thank you, and welcome to the channel. 👍👌
Thanks for your information, my heater is around 2 weeks old , must be up dated as the screws from control unit are shorter. Yes screen is difficult to read so I’ve mounted off the unit pipes are harder now , but priming program was slightly different . But mounting the pump different got my heater working many thanks 👍🏻
The pump needs to be at 15 to (closer to)30 degrees angle so the air bubbles can clear while it still gets lubricated by the fuel. It is best to prime the line and the pump MANUALLY before running it. While it pumps a million ticks to prime it runs dry... not good. Also the pump needs to be mounted on soft rubber with a bracket that itself is mounted on soft rubber to make it quite a bit quieter. May not be a bad idea to place the pump on these rubber mounts behind an encasing that yet will reduce the ticking to near nil.
...and the pump generally needs to pump up to the unit. outlet of pump needs to be higher than inlet 15 to 30 degrees.
i was going to mention this> The pump needs to be at 15 to (closer to)30 degrees angle
@@mrmrsd224 The pump can be mounted anywhere between 30deg and vertical. Vertical is best. If you insist on 45deg please explain why.
👍👍
@@petemolder These pumps need to an angle off 45⁰, they work on 30⁰ but need 45⁰. The manufacture of these pumps advise it, so why should we explain this!!
Yes! I recall seeing that the pump must be tilted 15 - 30 degrees, regardless of how crummy the instruction manual is, this was clear to me. VERY important. Rubber mounts are just brilliant! 😊
I also watched the complete series that you refered to. (Great series too) One point that I think you might have missed is that the outlet of the pump needs to be pointed in the UP position. He said something about the bubbles being normal and an actuall need for them was an important part of operation.
Hi Bob, thanks, I'll go check again. 👍
Wow! This video is over 2 years old, and it helped me 100%! My CDH is due in a couple of days, and of all the video's I've seen, yours is the best at helping me with what I need to do BEFORE I install mine! CHEERS from across the pond!
I drive long haul truck on the other side of the pond. My old truck had one of those heaters. Hearing yours fire up brought back memories. Mines was a Webasto and when it fired up the thing sounded like a jet engine. When they work they are the best heat source out there. Love the video thanks for posting. I'm actually looking to get one for my shop and that's how I found your video.
Hi Johnny, yea first time I thought she was goinna explode. 🤣🤣
Yes that brings back so many good memories back in the day tramping around England overnight stays and a nice warm Kip at night. No sat nav just the MK1 map book. 👍
The purpose of the fuel outlet being so high on the tank is because diesel fuel can be dirty and it gives it a place to settle and not clog up the filter.
Hi Dangerous, thank you. 👍
@@GTWoodshop Looks like a standpipe in a jerrycan would make a whole lot more sense on all counts ........
@@dancarter482 😁
@@GTWoodshop Great content. Was planning to us one of those flat 10ltr tanks as a day tank gravity feeding my bus oil stove - offtake in the lowest point etc. But have just read a few horror stories about them splitting or just leaking at the cheap seals. Think I'm going to get one custom made with all the breathers exactly placed and a robust shut off valve!
@@dancarter482 I had one outside my litttle office for 3yrs before it stared leaking, the joint at the filter degraded.
Excellent vid & sensible modifications necessary. Not overdoing at all. Future proofing & improving an otherwise cheap buy is for efficiency and durability. Kudos to you🙏👍
Hi Francis, thank you. 👍👍
Nicely done. Very clear, concise and lively. These inexpensive little heaters solve some problems for us all. These fixes should make them much more reliable!
Hi G.L. thank you. 👍👌
I noticed from your previous video an exhaust mistake but I am not sure the larger tube was the answer. It may temporarily solve the problem but in the long term need to change the angle of departure. From what I have heard everyone say about the heater, you need to have the exhaust gradually pointed downward due to moisture/fluid build up in the tube. Your tube looks like it is pointed up hill. The exhaust muffler on mine actually has a hole in it to let the moisture drain out. Most people don't know that. They lay it flat like a turtle shell when they should be turning it sideways so the hole on the side of the muffler is pointed downward.
It looks like the new position of your heater has corrected the problem of your previous location so the exhaust has a downward slope to allow the moisture to drain out the tube instead of building up moisture/fluid causing the back pressure you were told about. Peace
Thank you for all the info and updates on the heater, big hugs from MN
Hi Dan, you're most welcome Sir. 😁
I love my Chinese diesel heater it is so cool. Thanks for making this video. I just got mine running today and now that I know it works I can install it properly.
Hi Kevin, that's fab news mate, they are fantastic aren't they. 👍 Thank you. 😁
Chinese diesel Air heaters are a near 1:1 copy of Eberspacher and Webasto heaters so are great bits of kit, IF fitted correctly and therein lies most of their problems!
Fit it correctly and it's a fantastic little heater and will run for a long time without any hassle. 👍
Thanks for the helpful video! I think there might be a reason the fuel pickup in the tank is mounted where it is. I have noticed water and dirt eventually settles below that line, making it easy to dump/clean later. Enjoy!
Hi nadieselgirl, thanks. You may well have a point therre. 👍
this is correct , purpose designed to prevent debris pickup
There is an ideal angle that the fuel pump should be mounted at with a range of ° ! Don't ignore the manufacturers advice!
I bought one of these diesel heaters. I took your advice and I changed the fuel lines and put a filter in. I used some 2mm fuel line to cap them nasty sharp screws off. What a fantastic machine especially the new model with better screen. Best £90 I've ever spent. The pump on the unit is pretty annoying but I can always mount the unit outside the shed in a little box. They throw out some lovely heat 🔥. Going to see if it runs on old vegetables oil. I've heard it will run on any oil.
Great video thanks. Dean 🇬🇧
Thank you Dean. 👍
They definitely won't run on veg oil alone maybe a mix with diesel?
@@paulb8186 I use mine with used motor oil cut with diesel. I find it takes forever to start up and get hot. That said, I am going to adjust my ratio of diesel to oil and see what happens. Veg oil has a lower flash point then motor oil i believe, so it should burn it just fine. I would certainly cut it with diesel tho.
Thanks for the video, sounds like I watched the same video series. The item that really caught my attention was upgrading to an actual airfilter on the intake. Gotta keep the dust and insects out of the system. Webasto makes a very affordable serviceable unit. My heater is mounted in my 18 ft. 5th wheel travel trailer that is getting a complete rebuild this winter.
Hi Don, that sounds like an awesome project. 👍
Very Informative, and thank you for sharing. Even 1 yr later and I appreciate all the info and the reference to the John Mck series.
Hi Jeff, Glad it was helpful! 👍
Great video, I have just got one of these for my garage. Great bit of kit and burns surprisingly cleanly. I need to plumb it into a more permanent position but I have no doubt that it will help alot in the cold spells like we had a week or so ago.
Hi Mark, you'll be 'Toasty' in no time. 👍
As per DormantIdeas NIQ notes below, the pump needs to work using an inlet at the bottom, pumping up to the outlet. Ditto the angle, 30 deg is OK. The pulse rate quoted GHz, I think it is just Hz. 1.8 GHz is 10^9 pulses per second!! The other mods you made are good ideas, thanks. For my installation (at a hangar), I want to use an elbow to enable the exhaust to route at floor level. BTW, the exhaust muffler is the cause of the backpressure, extending the pipe with the same diameter (preferably within corrugations) should not be an issue.
Hi John, yes realised my mistake after publishing the vid, would drink fuel a bit a GHz. 🤣
Not sure if this has been covered in the comments. It appears that you have the protective plastic screen in place on the controller display which would account for the poor visibility. Also, you have the fuel filter installed backwards. You should be able to see the contents of the fuel filter from the "dirty side" closest to the tank. This way you can see if any debris is accumulating in the filter. The way you have it the debris would be hidden, out of view in the screen. Cheers.
Thanks for the failure list and tips to fix!😊
It's nice to see you finally put the door on the newish shed.
Thank you fireman Sam. 🤣
The one I got has the newer control and it reads entirely clearly. Mine is not in a box, but standalone and I keep the fuel tank a few meters away from the unit. It does a burnout when turned off so the soot is blown out of it. but if use the entire season, it is a good maintenance to open it up and clean it thoroughly to avoid to be surprised by a break down. It is wise to keep spare parts, like the glow plug, ... so that if it breaks down you are ready to put it back in shape. I also bought a second one, so if it breaks down I am not out of heat, I have time to fix it. These heater also come with the fan rubbing and fill fail to run... 2 screwdrivers strategically placed between the housing and the fan can push the fan out(careful, just enough pressure) and voila, it is freely rotating.
That was a very enjoyable and informative video, thank you for sharing.
Thank you Charlie, my pleasure.
I have just bought one my friend, (8kw) in black (25th Sept) and they have upgraded the LED screen with a square double sided sticky pad, I also noticed the pump was upside down (looking at your video) where you connect the plug to it was facing up, so I will face mine down like you have done, also the fuel pipe is all the hard plastic and not the green soft tube, there is no filter so I am waiting for that to come, along with an ultra quiet pump, spare glow plug and some small Juberlee clips, I did find a lot of the screws etc were not very tight, so fixed that as well, I am going to have to cut the fuel line near the tank to fit the filter in, then fingers crossed, should be good to go.
Thanks for all your information that you have given us. (I have subscribed to your channelas well )
Hi Charlie, thank you. n investment you will be delighted with I'm sure. 👍
Hello Graham, good to meet you. I think you came up in my you tube feed because of the diesel heater as I am not a wood working guy. I do have a shop and I do love tools but I came to the realization as a young man that I don't have the patience to do fine woodwork. Not that my shop hasn't kicked out the odd product that vaguely resembles a bird house or a bird feeder. I just wanted to say I like your presentation style and I wish you luck in the growth of your channel.
Hi Kokanee, thank you. 😁👍
I just ordered one of these in Christchurch NZ, and THEN looked up about reliability. Priorities right. Thanks to this video, it's all good again. Easy fixed. I believe the kit forms of this machine are bought by the Czechosolvakian army, so they must be pretty good. Anyway, thanks for this video, good old fashioned, layman, thorough explanations, advice and detail. Stopped me having another breakdown :)
Hi Ian, you're welcome. 👍
Czechoslovakia doesn't exist anymore...
Yes I watched your install videos & also John McK both helped a lot 👍🏼
Thanks Andrew. 👍
Ordered a similar heater for my garage. Thanks for the well presented videos. I'll know where to go and what to do if owt goes wrong.
Hi Ben, thank you. Don't forget to fit a filter! 👍
@@GTWoodshop It's on order mate. Thanks again for your informative videos. I'm just having a shufti at John McK's videos too. They're excellent.
I just bought one of these but haven't tried it yet. I watched a video detailing 12 points about these heaters & he said that the fuel pumps should be mounted at 15 to 30 degrees which is exactly how yours, & mine came. Who knows who's right!!! I agree about the screen brightness, they seem to work OK from above or below but not straight on which is the opposite to how screens normally work
I always like to see people improving things make a cheap stuff perform better. Don’t condemn it Chinese/ German Italian or whatever cheap or crap just show the world what you can do to make it better. Thanks for sharing bro you are awesome 💕
Thanks Jimmy. 👍
No insurance if there is fire, and one of these heaters is involved.
1.8 gigahertz Oh yes you are very reliably informed . Also there is no pressure in the fuel line . The pump pushes the fuel at the rate you set but there is no *high* pressure in the fuel line .The only important thing in changing the fuel line is the build quality .As other have said keep the fuel pump at 30° pumping upwards to avoid air pockets . nice setup you have
I have 5 of these heaters. The fuel outlet is raised up from tank bottom to allow space for water and sediment. Thats why no filter required. The pipe is fine, the pump will expand the pipe marginally until the pressure peaks at the average pressure required. This also smooths the fuel flow. The pump will be lubricated at any angle, diesel has no surface tension and will froth inside the pump. This forms small bubbles despite the mounting angle. No problem there either. The pump itself is a brass plunger in a cylinder driven by a pulse solenoid. You may be right about the exhaust though, never done it to comment.
A couple of things. First I thought the output of the pump should always be facing upward. Second the screen should be easier to see if you took the projective plastic film off of it.
Also, that white tubing is less heat resistant than the original green tubing.
Nice work! Thanks for this! 👍
Very useful information! Thank you very much, I have just bought one, but not installed yet. Now I think it will be easy! With regards, Åge Ernst Øvrebø, Norway
Hello Norway and thank you. 👍
You mounted the fuel pump upside down. It's supposed to pump up against gravity in order to maintain fuel inside to keep the pump lubricated.
And let the air escape.
I know who you are talking about before you mentioned him. He's a genius!
Great video, I was going to say I saw the fuel tank on a bit of an angle, you explained why at the end! It would be nice though to buy a unit with out having to upgrade it eh!
Great video and explanation of issues most appreciated
Hi Ross, thank you and you're welcome. 👍
Thanks for the fuel pipe issue. In return your tank outlet is well placed, because dirt will set on the bottom of the tank.
Thanks Bernd. 👍
Thank you for the information!
You should have just a link up and saved us time watching this
I'm running 12 feet of exhaust(extra free heat) , same diameter as exhaust that came with it. My start up from cold, is just over 2 minutes. Your theory is bunk my friend.
Great video.
These heaters are meant for RVS and huge semi truck sleepers.
I am pretty sure the exhaust fumes need to output exit workshop. If your climate is MILD, maybe keep your space warm.
Hi Ed, thank you. I agree on all your points, especially the exhaust. 👍
Thank you very much. Very useful info.
HI Rangeo, you're welcome.
great vid thanks for your time
Just waiting for my heater to arrive for install into my workshop, after spending silly money on electric heaters, gas was never an option for woodworking and kiln dried wood in my workshop. so thank you for this video, I shall do the mod when it arrives, I always thought the pump had to be at roughly 45 degrees or there abouts , i see you put your directly horizontal.
I thought I'd try it and see if it caused a problem......... Still sound as a pound 2yrs on. 👍
I don't think the pump should be installed vertical, but rather at a 30° angle from horizontal, plus it should be pumping upwards not downwards. Other than that, a very informative video
Very well done!
Hi Patrick, thank you.
Great video👍
Hi Adam, Thank you. 😁👍
Great stuff, well spoken,👍
Hi Acheeez, thank you. 👍
i would like to say that i noticed that the outlet of the pump is pointing downwards .It should be pointing upward at 45 degrees to alloy any air in the pump to escape.if air remains trapped in the pump it can cause premature wear.The 2nd thing i noticed is the display screen is shipped with a plastic shield to protect it from scratches during shipping .You must remove that plastic by peeling it off then the screen will become clear as glass.I hope this helps you.
Hi Denis, thank you. 😁👍
great video, well presented, and very informal
Hi Eddie, thank you. 👍
I’m excited to learn something here. 😊
Thanks Beatrix
I will try your pump setup because it made sense. To make it clear, the OUT part of the pump will be facing down (with the wiring side). So, the pump IN-take will be on top coming from the tank (filter). Based on your setup. Thanks.
HI J, yes. All of the info I have managed to find about the pump suggested that the pump should be vertical but didn't mention anything regarding the intake being up or down. Mine is still running beautifully in that orientation. 👍
J, the pump should absolutely be mounted with the input below the output. Fuel, and any bubbles should be exiting via the top of the pump. Yes you can mount the pump vertically, or at incline an angle, but Do Not mount it horizontally or with the output below the input. In your terms the “OUT part” needs to be facing up. Watch this other tutorial. ua-cam.com/video/jCZhjGyR3bo/v-deo.html
Thank you
With reading the screen, I mounted it onto a sheet of ply to install on an extended lead about 5 meters long to the burner mounted on an outside wall, I have noticed that looking down at an angle on the screen makes it more clear to see than looking directly at it. It seems to be comprised of a white led backlight that isnt very bright at all and you can see this white led light leaking forwards at the edges of the screen.
The fuel line is above the bottom so you don't get dirty diesel or water going in the unit, the frequency is Not Gigahertz of the pump it's Hertz or Hz
good sound advice thank you
Hi Kieran, thank you and you're most welcome. 👍
The filter should be the first often in the tube from the tank. It's protecting the pump from wear due to the impurities in the diesel.
Point #2, you don't want to suck from the very bottom of the tank. That's where most of the garbage collects. My tank has some debris at the bottom that I'd rather not get sucked up or clog the fuel line. That's why it's up little from the bottom.
Great info.
The softer out put fuel line actually acts as a compensator,smoothing out the pulses and cushioning the fuel pump stroke and creating a smother burn. But you must be sure to bleed properly. My units have been running great with the green fuel line.(maybe they have improved it) I purchased a quantity of it and use it on weed whips, chain saws and other small engines with no problems yet. As far as the loose fuel tank i just applied a piece of thick black foam gasket materal on sides and end of the tank now its isolasticley kept in place. I run 4 of these heaters in Wisconsin winters 24-7 and the only problems so far is having to replace 2 glow plugs. My fault for letting them run out of fuel and trying to start them without priming them first. Easy fix.
Never had any problems with mine at all...BUT: I run it on home heating oil, which may be a lot better for it than diesel.
I did shorten the screws mentioned, and I did extend the exhaust with the same diameter tube. Also, I always run it at full heat for 5 mins before shutting it down, and shutting it down "cleanly", i.e. pressing the off button, and not just disconnecting the power. Your workshop appears bigger than mine, but you don't appear to have the likes of a large metal lathe, and a milling machine, both of which "soak up" any heat, I could do with a bigger unit. Nonetheless, I have had mine for 2 years, and am very pleased with it.
Hi Cossiedriver, yes I always perform a clean shutdown on mine. I don't run it up to full before shutdown, but always let it go through the shutdown cycle. 👍
Great video but I’d suggest using a socket to tighten the clamps. When I first set mine up I used a screwdriver but had some leaking
Hi Derek, great point thanks for the tip. 👍
Nice work! But you just made it worst! You put the pump upside down, the exit must be up, not down, the air is going up by gravity, so having the pump trying to push the air go down is not good and probably harder to prime! I put the exit up and works really good! Tkx for your video!
Thanks so much man!
Very helpful 👍👍
This was a great help 👍
Very helpful, thanks.
You're welcome!
Excellent tips about the fuel line, fuel filter and exhaust back pressure but I think the fuel tank is locked in place by the hole the tank lit protrudes through, mine is a snug fit at least anyway.
Ok, I’m only 15 seconds into this video, and I’ve already subscribed. Go ahead Mr. Bond, tell me more about Chinese Diesel Heaters! 😂 Seriously though, well done Sir!
🤣😉
Great Video
Thanks JC
1. you could replace the screws with shorter ones or even get plastic rivets like those used to hold circuit boards to the metal frame where there are 2 pieces a piece that goes into the hole and a pin cap that goes into the rivet to expand the prongs and hold it in place.
2. if you dont want to do that you can take a scrap of wood about half inch or 12 mm thick and place over the back of the front plate where the screws are and that will prevent the tank from being slammed into the screws.
3. you dont want to have the fuel connection to the tank to be right on the bottom because if there should be any settlings it could get taken into the pump and clog the pump or even the heater.
Very interesting thank you
Hi Jamison, thank you. 👍
_Here's a quick tip for the controller. Take your finger or something sharp and peel back the plastic film off the controller's face; it will make the controller much better to see._
👍 Hi Sui, yea, figured than one, thanks for the tip anyway. 👍
Hello mate. Very helpful video. Many thanks. Just a little heads up. Both links for the fuel pipe kit do not work. I cut and pasted the text description in to ebays search bar and it worked. Thanks for the link. All the best.
Super , en plus je travaille mon anglais .
Congrats on a very successful and hopefully long lived repair to the heater. Amazing how sawdust makers successfully dive head long into other disciplines. Does the more steady/uniform temperatures in your shop positively improving the application of finishes on your projects?
Thanks Dan, I'm yet to find that out but its a good point. I'll be applying a spot of finish to a little project tomorrow hopefully, videoed of course. 👍
If you remove the protective film from the display, I'm sure it will be much easier to read.
Thanks
According to 2022 experts Pump out put up with pump angle 35 to45 degrees which allows air to properly purge also pump angled for best burn efficiency.
if you want to double the heat output. get with a plumber and get some galvanized pipe from a chain link fence.
have them thread the pipe and install about 40 feet of pipe inside of the shop. use a few of the computer fans to blow air along the new pipe. the goal should be that the actual exhaust of the building should not be more than about 20 degrees over your shop air temperature.
THANKS !!!!
Great vid thanks, I think you would see the LCD better if you removed the screen protector film. It's easy to forget it's there.
Another comment, 3-M sell a two sided tape that will secure the fuel tank, also purchase a slip on fiber glass heat shield for through the wall mounting. If you do research such as yourself these little heaters will give good service.
Does anyone have an idea why mine instead of filing the fuel line with diesel drips it through the exhaust? What to fix and where?(I’m really trying to get an idea on what it could be before I disassemble it as I have very little time between the work and kids)
thanks for great info and solutions ,i also cannot see the screen ,so im going to try and put it somewhere dark
Hi Drexel, thank you, and you're welcome. 😁
My Heater makes that same burping noise. Its coming from the Air intake filter. Not sure why it makes that annoying noise just on starting.
Great video and informative, Ive just ordered the same heater for a 16x8 work shed would this heater actually keep it warm on cold days as I use laser cutters and the water cooling system needs to stay above freezing temps.
Hi DJI, with ease I should say, I run mine on 4.5 for about 20 - 30 mins, then drop it to 1.6 for a while more. Running at 1.6 can vary depending on temp outside but longest has been 3hrs. Hop that helps. G 👍
Great share - does anyone in the US know where to find the upgrade kit? I haven't been able to find it on ebay.
Have you removed the protective covering from the display panel, looks like it is still stuck on.
Great vid thanks .. just noticed the plastic film is still on your controller peel it off may increase the visibility issue that you mentioned?
Hi Griffith, yes it was. I really have an issue peeling these off, I always leave them on until they literally fall off. Its gone now though. 😁👍
