Chinese Diesel Air Heaters - Part 10 - Special tools, Tongue in cheek

- This is a bit of a tongue in cheek reply to ribbing comments I have received from video no 9 about my special tools. However there are also some serious bits in the video as well.
If you have carbon and soot build up in these heaters, particularly in the atomizing screen and in the little igniter breather hole, the heater will not start.
There are two major causes for soot and carbon buildup in these heaters -
1. Poor instillation with restrictions in the burner intake air, and restrictions and back pressure issues in the exhaust.
2. Burning different types of oil and oil mixtures in these heaters.
Burning engine oil, vegetable oil, whale oil, snake oil, alligator oil or toad oil, direct or in a diesel mix is a sure way to set yourself up for future problems as all oils produce large amounts of soot and carbon residue when they burn. This soot build up will prevent the efficient operation of these heaters, and in serious cases require a full burner replacement. - Auta a dopravní prostředky
🤣 Fantastic! Great breakdown of tools too 🙂
Good to know about the oil. I had read somewhere about having two tanks and switching between pure diesel, and a 50/50 oil diesel mix, and then back to diesel before shutting off, which I may try.
Thank you John,
Great vid... had issues with my 5kw not firing right and exhaust pushing massive white smoke.
I've took it heater apart and noticed a lot of built up inside the combustion chamber.
Also around the glow plug and the burner screen.
I've clean it with engine cleaner and put everything back together... took about 2 hour.
Thumbs up John.... it worked out great and now my heater is back n running.
Thank you so much for your vid.
Pleased to be able to help Thomas. JMcK
Appreciate your time you put into these videos very much John
Thanks Richard. JMcK
John, you ROCK!!!
I love your very thorough vids. Thank you so much.

This Old Bugger has got to be a KIWI. (New Zea lander) Great watching informative watching with ingenious - make do thinking - a bonus. Quite unique. Great Work John. Magpie in the background??? Nah! he's Kiwi
No, no, no!
I am dinkie di Aussie. ...... True.
NB. Birds singing are both Magpie and Australian Butcher Birds.
I live on a rural property in eastern Australia.
Do I really look that old..... Oh dear! ... JMcK
just found you and binge watching . Thankyou so much BRILLIANT!!!!!!
Pleased you like the videos Mitma. JMcK
Thank you John, and hello from Ireland.., I'm just going to buy my first diesel heater, and your videos have been an amazing help, I feel confident now, to instal and use correctly...gratefully. Michael
Pleased you found them helpful Michael. JMcK
Appreciate your videos very much John!
Your welcome Mr TS. JMcK
Very good videos. I had a friend bring me one of thies diesel heaters with a bad glow plug. I went to a auto parts store got a deep socket that fit it. Then I milled .25" slot in it just like an O2 sensor socket. Worked like a champ. We also cleaned the combustion chamber. All is good now. Have a good day from the USA.
Thanks for the feedback KLH. JMcK
What glow plug did you use?
Lefty loosee righty’ tighten,no wonder I always have one shoe that fall off🤡 very informative videos John plenty people will find them helpful 👍
Wow! Does that ditty work for shoes as well? You learn something new every day.
Thanks for the effort John, it's much appreciated. I can't tell you how long I've spent trying to get my heater to start again ! Im now thinking it must be my ecu motherboard. So I'm just about to go through your " back catalogue" Thanks again..... Karl (Glasgow)
Hi Karl, I hope I was able to help a little. JMcK
@@johnmck1147 👍
Thanks for your feedback John. Yes a 5kw heater should easily keep 200sm warm for you if you have reasonable insulation. J
Wish i had you as a Shop teacher in High School (be it Automotive/wood/metal shops!) Your knowledge, explanation, and humor are excellent for paying attention and learning. Im sure your Scuba students were stoked on you!
Although this video was humorous, I think this is a good video to watch (and i almost didn't because of your suggestion not to). I recommend editing that suggestion out for future viewers. The info on tools is good (pencil included). I plan to live off grid and find it a good idea to carry spare parts / special tools and your knowledge (notes).
Additionally the part about the atomizing screen being installed with welds down and positioned away from fuel delivery hole, as well as a clean fuel hole is huge! Keep the Humour in all your vids.
santa cruz, calif.
Wow Twinfin, thanks for the positive feedback.
Pleased you also enjoy the silly humour.
Cheers, JMcK
Love this guy!
haha had to laugh at the spanner fork, Hey thanks for sharing your diesel heater vids very understanding and enjoyed watching them
👍
thank you john the heaters metal mount is the one that has metal ring around to protect the inlet and outlet, if I have to put it on it's side which is the glow plug side thank you john
Hi Denis, you just take the top cover off, you can see the glow plug easily, just tilt it on the side with the glow plug goes to the top. JMcK
OMG the cheese joke, you made my day, thank you :D
👍
Absolutely love your tut's on these machines. I'm not a brown noser by any means, but I hang off yt waiting for your next one. Wonder if there's enough content to demonstrate how much a rise in temperature you can attain in a given (enclosed) area? I spose that could be worked out given the data already known. Maths wasn't my best subject at school, but I suppose we know the heat output and the area to be heated, and I suppose the ambient temp would be needed too. I only ask because I have high hopes of this little 5KW heater keeping my large polyhouse (200qm) at over 12degC during the coldest days in winter. Coldest day is +2 so hopefully won't be a problem. many, many thanks.
Expected a glass of Grange Shiraz to the cheese. Anyway, great video once again!
Thanks to you I just ordered a 2 kW heater. I really don't need it, it's just for fun to see how it works (if it works).
Being a senior citizen myself I guess you have my understanding..
Thanks for the feedback Torstein. Forgot to chill the wine. Now don't let the grey hair fool you, I am really only in my early 50''s (or wish I was)
Interesting to see if you get a real 2 kw heater or a 5kw marked as 2 kw. The real 2kw heaters are around 300 mm long and weigh around 2.4 kg. The 5kw heaters are around 400 mm long and weigh around 4.5 kg
This one:

See different size deliveries from feedbacks to this supplier now, one customer had a 2 kW and another received the 5 kW. Lesson learned must be that you wait for actual delivery from China, and THEN buy appropriate size of the car.
If you had not mentioned it yourself in a video, I could never belived you were a Senior, mid 40's was my first impression.
can you use choke and carburetor cleaner to clean the screen
Atomizer insertion tools will contain a graphite core rather than a lead one, they have never actually contained lead, but a combination of graphite and clay.
👍
How do you reset the lcd display unit?
Another great video John.
Can't find where to buy the atomizers.
Must be searching the wrong terms.
Thanks Greolt,
Try looking on Ebay for atomisers for Eberspacher D4 heaters. You could start here.
www.ebay.com.au/itm/263738584595. There are lots of suppliers.
I have been buying mine for around 80 to 90 cents each.
Did he say toad oil? Hahahahaha!!!
Fantastic series! Congrats from Ireland. But where are episodes 1-9? And what is on them? Would love to view somewhere if they're gone from CZcams. Thanks.
Hi Alastair, these videos were done some years ago, and I have not removed any of them.
I will now go and see what has happened. JMcK
Hi Alastair, they are still there. Link to no 1 below.

I was pokin' fun at you pokin' fun at things. We don't have a lot of 'gators here in Virginia, but I agree 'gator oil would be pretty slick stuff. I had to drain a tank of home heating oil and have it stored in plastic 5-gal. kerosene cans. I am planning to use it in the Chinese heater I just bought. From a lubricity standpoint, do you see any problems using regular home heating oil?
By the way, your tutorials are terrific and so helpful! Thank you for posting them!
Hi Doug, as I understand it, your home heating oil is just kerosene that has some sulphur in it. If so, it will be ok to burn in these heaters. The sulphur gives the pump lubrication. JMcK
I John. I have watched all your videos. Thank you for making them. What is your summation on these machines. This may have been covered before.
A caravan repair man saw I had purchased one of these and said that they are dangerous and should not be installed. I am a bit worried now. I can’t see any reports that they are unsafe.
What’s your comment on this.
Thanks.
Hi Slade,
What reason did your Caravan man give for that statement?
These Chinese Diesel Air heaters are almost a direct knock off copy of the German Eberspacher heater, and these have been around for decades.
In my opinion these Eberspacher copy heaters are excellent and very safe heaters, if installed correctly and operated correctly.
These heaters are so cheap compared to the genuine heater it has opened up a market for the masses. But those who buy these heaters are unlikely to spend many times the heaters cost to have them installed professionally. A number of these DIY people make some serious install and operation mistakes, and then blame the heaters.
The main reason I did this series is to try and give some guidance and knowledge to the self installer.
However doing things wrong like using the wrong fuel line, poor service maintenance (see video about gaskets), bad install or operation can cause safety issues. Just like everything else in life, be it making coffee, or setting a mouse trap.
Cheers. JMcK
Wonderful set of videos! Congrats and thanks for your sharing!
Nevertheless, I would like some expert advice. I’m thinking about mounting my diesel heater under the floor (exterior).
Is there any cons? What about the inlet of cold air?
Best regards!
Hi Ricardo,
There is no “one way only” instillation of these heaters. Yes you can mount it under the floor, providing you can give the heater protection.
Under the floor of what? A vehicle, a house, a cabin, a caravan etc?
There is no issue drawing cold air from outside rather than reheating internal air. Some people prefer heating fresh air, even though it is less efficient.
The main issue is heater protection. In a vehicle, is it protected from road debris etc?
You also will need a filter screen on the air inlet to keep out any critters from the heat exchanger.
Cheers. JMcK
@@johnmck1147 Thanks a lot for their answer. It will be under the floor of a camper van. And yes, it will have a aluminum case.
Congrats once more for your tutorial videos. They are great and a big help. You are the diesel heater guru! 😊👍🤝

John, I am curious how the fuel is introduced into the heater, haven'ttaken mine apart as it runs fine. Does the fuel drip/squirt directly on to the screen before entering the combustion chamber and under what appropriate pressure? Once burning, does the fuel still pass on/over the screen. If so, it would seem the flame is originating on the screen then expanding into the combustion chamber. Is this so? Keep up the GREAT analysis, your work is being recognized as the best available.
Hi Robert, I will go into this deeper in a future video, but there is a second large atomising screen around the main burn chamber. First the glow plug ignites the diesel/air mix at the small screen then the flame ignites the main burner which acts like a big blow torch. More info in a later video. J
@@johnmck1147 Thanks John. Still curious how the fuel is "injected" into the unit, the pressure, the pathway. You're doing a great job informing those that are curious and to correct the enormous amount of misinformation out there. Fascinating little inexpensive heaters.
Why not use spray on carburetor cleaner or throttle body cleaner to remove the carbon?
Carby cleaner can be helpful at removing carbon buildup. JMcK
That's funny as John. Gotta luv the cheese mate.🧀
👍
hi john I want to put the heater under the floor of the caravan with just the hot air going into the caravan I have some question to ask, is alright to put the heater in a metal tool box and if so will it get to hot, because I want to seal the box so no dirt gets in, is there any down side to having it under the caravan ,all so you mention some were on your videos which I can not fine, about a facebook site were I can talk to people that have them set up like this I'am eager to hear from you as I'am ready to install it now thank you john
Hi Denis, if done right you can put the heater under the caravan in a box.
1. The caravan needs to be high enough so there is enough room and the heater doesn't hit the road.
2. A sealed box is ok as the heater cools from air moving over the heat exchanger, and the metal box will also dissipate heat, but you will need some air gap around the heater, say 40mm to 50 mm.
3. Where is the inlet air going to come from if you seal the box? Are you going to suck it down from inside the caravan?
4. You could consider mounting the heater on its side under the van, but only the side that has the glow plug on the top. This way the combustion air inlet and the exhaust would exit on the side and not out the bottom giving the exhaust and inlet some protection.
5. Make sure you have a screen on the combustion air inlet to keep out bugs, and in dusty conditions you may need a foam type filter.
6. Keep the exhaust away from the combustion air inlet.
Good luck, Cheers. JMcK
Just got a new one from ebay and im not getting power to the controller. Checked fuse and I'm getting 12v to the ecu but no voltage to the controller? What else can i Check
Hi Erinson,
If your heater follows normal protocol, the controller wires will have a triangle plug and socket.
There will be three wires, generally red, black and blue.
The blue wire is the sense/data wire, the red is 12+, and the black 12V -. Put your multimeter on the red and black wires coming from the heater. Check the voltage.
No voltage you have issues with the plug, wiring or ECU.
Voltage present, you most likely have a bad connection or a dud controller.
Also check that the wires line up correctly in the plug and socket. Very occasionally the the polarity of the wires is reversed.
I hope this is of some help. JMcK
If I use alligator oil as my fuel, should I add any special lubricant to the mix?
I would think alligator oil, like snake oil, and shark oil would be self lubricating.
Truthfully, your special tools are nothing to joke about. But, you did make it fun showing their use. The tool box for those special tools that I'm going to invent will be needing a name.....Any suggestions?
Not really Admiral. Just male sure your special, multi purpose insertion tool is 6 sided (like the socket spanner) and not a cheap round copy. J
John they are great videos and very helpful I’ve just ordered my Diesel heater and I will be looking up your page on the control if I’ve got any problems can I contact you on getting the diesel heater to work properly thanks mate
Hi Billy, I am happy to help if I can. JMcK
John McK 47 Hi John I wondered if you could send me a quick drawing of the fuel system from the tank to the unit so I can follow it in the angle of the pump cheers mate
Billy Hill ,
Very simple, come out of the tank, through a shut off valve if you wish, then through a filter, then into the pump. Install pump as close to fuel tank as possible, install pump in position that it has less than a meter of head and less than a meter of suck. Install pump with an upwards angle of greater than 15%.
Any issues please email me at johnmck47@outlook.com.
Loving your videos, do you just get any chinese made heater on ebay or are some better then others internally? cheers
Hi Nigel, the mechanics of them all are pretty much all the same. I suggest you look for a supplier that has an in country warehouse if possible, and one with good reviews, and accepts returns, then choose one that has a controller you want. (more on this in the next video). The other accessories are not so important as they can be easily sourced. Good shopping. J
John McK 47
Great, your a legend, looking forward to your other videos, would be good to see you do a complete pull down on one.
nigel simmons
Hi Nigel, yes, I have one planned for the future.
My deisel heater has no codes, it seems to start ok but blow lots of smoke then wants to shut down. The screen is not blocked. How do I test the glow plug?
Hi Bruce,
If the heater actually starts up and runs for a bit it is unlikely to be the glow plug. If the glow plug does not light up the heater will not start.
Is this a new heater, or an old heater that used to run ok in the past?
If a new heater, they will blow smoke on first couple of starts until any big air bubbles go.
Now look at the fuel delivery system.
Are there any small leaks in the fuel line?
Do you see any big (not little) bubbles in the fuel line?
Have you got good fuel hose connections? (No leaks)
Are you using thin bore hard nylon fuel hose on the delivery side of pump to heater?
If an old heater that was running well in the past.
Check for clogged fuel filtrer.
Check fuel line for any leaks.
Strip heater down and check for carbon buildup in burner chamber. Clean.
Regards. JMcK
@@johnmck1147 thanks John the heater is 1 season old had been working fine. I will check you recommendations. Cheers

What sizes are the spanner or box tool.
12 mm James. JMcK
Jeez, I was waiting for that... T K 🙏
is there a way to change to the temp setting from C to F for us dumb yanks who don't understand the metric system
It is not something I have tried to do. I am away at the coast for a few days, but I check when I get back home.
funnily enough they are selling some kits with nothing more than a screw to remove the gauze..i think they pinched your idea :)
👍
Don't listen to this kibizes, your improvisation was - is ingeniouse and works very well. Just ask them how many people have followed them on youtube in comparrison with you... speaks for its self... I apreciate it to the fullest and certainly will watch them all, unlike your naggers of whom I most likely know none....
Hi Bernd, pleased you find the videos helpful. JMcK
