Almost SILENT RUNNING Chinese Diesel Heater THREE Modifications | RV Motorhome Rebuild
ฝัง
- เผยแพร่เมื่อ 27 ต.ค. 2021
- We carry out THREE modifications to the portable Chinese diesel heater including TWO to make it almost SILENT running and certainly one of the quietest vanlife diesel heaters that you will find. Three simple modifications that you can do, including a modification to the exhaust pipe and one forming an effective pump silencer.
Below is a guide to the products that you will need. As well as in your van, Diesel heaters can also be used at your home to heat workshops, garage and sheds.

That’s the best method I’ve seen on TH-cam to quiet down those heaters. Well done
Thank you very much for that feedback, it is really appreciated.
I do appreciate your work, but On a Bitter cold winter morning , I reach out of my warm bed and press the button and Wait ! Then the little Tick, Tick, Tick starts , then the Whoosh of the Hot Air ! I love it ! Pull the blankets over my head and wait until my van is Toasting !
That sounds perfect for a winters morning Robert. These diesel heaters do a really great job.
I used to have noisy pumps in our old greenhouse (to water the plants remotely) they were so noises I built a small box around them and filled it with sand, they went from being able to be heard from the other end of the garden to virtually silent overnight lol
That sounds a great solution to me 😀👍
There is a certain way to get the system quiet! Get rid of the solenoid pump and replace it with other method pump! Never ever that annoying klicking and desperate sound insulation no more!😊
That is of course another option yes.
Just use the original pump instead of wasting money on a different one. You can completely eliminate the sound by suspending the pump instead of solid mounting it. I used a small cable tie so the pump is at a 45 degree angle. Then make sure you wrap it in some kind of padding (a piece of pool noodle works prefect) or insulation of some kind. Anything to absorb the pulses. I can stand right by my heater and cannot hear the pump at all.
Good job on the sound deadening, like the exhaust wrap. Looking forward to fitting mine over the winter. 😎👍
Thanks. It's certainly made a difference in the noise levels, time will tell how quiet it really is when we build it into the base unit and it become further sound insulated. I am not convinced about how the exhaust pipe is secured, so I may revisit that later with a better jubilee clip than the manufacturer supplies. The intake hose is also rubbish, crushes too easily, and a better pipe is needed there.
Thats a great Modification thats super quiet. I am going to do this. Many Thanks
Thank you for the feedback. We would love to hear how you get on.
Neat job there. Nice one. It's great to get rid of noises in the van, as you do tend to pick up on things like that, especially when you live in the van. We haven't got one of those Chinese diesel heaters, but we have tinkered with the idea of the other type which has a separate tank. We're holding back at the moment, see how we cope this winter. lol.
Thanks Andy. Yes, a 2kw tank-less version would suit your motorhome better. We have more work to do with the heater before we use it, including a method of sealing / enclosing all of the exhaust pipe, a feature to deal with on these units stood on legs, which will need some thought for me in the coming months. I will be using the heater in my garage over the next week, as I have some work to do in there for the RV 😃 I have central heating in there, but we are not using the house gas central heating at the moment.
Very clever.
Thank you for sharing.
Greetings from France.
Thank you Cyril 🙂
If you soak the bandage in water it is much easier to wrap tight , it then tightens further once heated and dry . just a tip if you ever do another wrap .
Great tip, if I need to remove the exhaust again I will try this for sure :-)
And when dry, Paint it HT paint 😉
Salt water is better thats how they seal flues in the med
@@MrC3dr1cB I wouldn’t paint over fiberglass like that, paint the exhaust itself with that, or cerakote it if you care that much and then wrap it. You’ll be able to touch the exhaust and at most feel a little warmth if done right
@@KDlGG Cool-It High Heat Coating provides long lasting protection for any hot surface up to approx 800 degrees C. This coating is recommended for use with their exhaust wrap, as it seals the material and provides lasting protection from oil spills, dirt and road grime. Its use is by no means limited to use on exhaust wraps though, it works well on exhaust headers, engine blocks and starter motors etc.
Well done John. That looks a job really well done. Love the ingenuity!
Thanks very much. Rob also saw it this morning, he had not seen the work being carried out as he is on a building job for a few days, and he said it's much quieter now.
@@VintageRVAdventures It would be nice once the project is finished to revisit again for a final comparison. Great invention though once again ✅
Great vid, thanks for the tips. I'm defo gonna try some of these when I get my heater. Still haven't quite finished the van insulation stage so I've got quite a way to go but there's no rush :)
Good luck with your van build project.
Much quieter so job well done.😁👍
It certainly is 😃 ...thanks both
I will try thx for the tip!
Thanks 🙂
The new autoterm planar diesel pump absolutely amazingly silent.
Thanks for the information.
Use Marigolds while wrapping.
When wrapping is done, blow the wrap over with a plumber's blowtorch to melt the loose strands off.
Remaining loose strand-ends will melt to little balls that can be brushed away outdoors,
Two really good advice tips there, thank you for sharing the thoughts.
oh dear :)
1. gloves
2. soak the wrap in water for a few hours before you plan to use it.
Good video though, I'll be trying these mods on mine.
Good tips, thanks for sharing.
I put a 1/10th watt LED light at the top of the end of the outside of the fuel tank top using adhesive aluminum duct tape. I can see the fuel level from 10 meters 33 feet away. The light had to be at the top as when I tried it at the tank bottom, the whole tank glowed green with diesel fuel and blurred the fuel level.
That sounds a good idea, great tip.
I used a foam pipe that's meant for insulating 3/4" and 1" plumbing. Here, they are dark grey and have been slit down the length
Ah yes, I know the sort of thing that you mean Peter. I hope it helped improved noise levels for you.
Hello 🖐 thought I'd subbed after checking your channel following Helen & Karl's mention the other week, but I hadn't. I have now.
While I know nothing about fitting heaters of any kind, Well Done on the problem solving mods and finally sorting yours out. ATB, Sue
Aww thanks Sue. We have just also subbed to your channel. We will take a look through your channel later tonight when we get chance to sit down.
@@VintageRVAdventures Thank you for the sub back I appreciate it and wish you all the best with the van and adventures. Great times ahead! 👍
I actually like the tick, it's very reassuring sounding, I just don't like it super loud. Doing this to mine right now
I agree, it can get quite annoying.
Hi, interesting video.
Have you had any problems with the burner unit overheating or throwing up any overheat error codes ?
Thanks,
Steve
No. To be fair we have not had it that long. We had an error code once as the fan was catching the housing. I think we made a video on it.
Good luck trying to get round Cornwall in that van.
We will let TH-cam know how we get on in Cornwall if we go lol ... Perhaps we will follow a coach, bus or bin lorry when we are there :-)
Great ! But, for the same vevor 8kw I built a silent box , dipend of the space is possible use. Grats from Italy.
Thanks for the feedback.
They make a sleeve material that easier to slide on the pipe like a sock.
Okay thanks for the tip.
Would have been useful if you had shown us the sound after each modification. But thanks for the upload and it certainly made a difference. A lot of the pump and heater noise resonates through that cover so that was a good idea to put the sound deadening material on the inside. And those slits aren't air-vents - you were right second time - they are simply so you can see the fuel level.
Sorry for that
I actually dont mind the ticking of the pump, relaxing in some ways even.
Happy new year 2023, have a good one.
Oh there is something wrong hear.
@@lodwill4007 Whats wrong?
Put the foam between the case and the fuel pump mount to isolate the pump from the case. Rubber mount everything that makes noise
That is certainly something that may assist further.
Great video thanks a lot, one question in yoir opinion if i put this unit under or boxed next to my static carsvan would it be that noisy that it would upset my neighbour 5 mtrs away and or would the noise travel at night thanks a lot Paul
A good question. So, the video is really about quietening the annoying click noise of the pump for the fuel. But, your issue with that kind of external set up will mean the fan and fuel burning noise (sounds like a jet engine) will certainly be an issue. I think you will struggle unless your box and and heater ducting is super insulated for sound.
Amazing work! Can you tell me how thick that insulation foam is? I have been trying to find some on Amazon but they are mostly around the 10mill or 8mill range and what you have looks thicker but its hard to tell from the video :)
Thank you. I would estimate the foam is around 7mm thick.
I am just about to order one of these heaters, so a very Interesting video, just one question, won't this make the pump overheat?
We have not experienced any overheating problems so far Steve. We are not full time motorhome users though, so we almost certainly don't have it on as often as others might.
😊👍
can even bye a quiet pump as well
Happy new year Peter
Why not insulate the outside with the same material ? Fab vid, am going to do mine this weekend.
You could do that.
Is that a 5kw or 8 kw unit? Does it have a Alpine mode setting feature? If so, could you tell me the hot air output temperature at setting level H1 Alpine mode. Thank you.
Its is the 5kw version i think.
What's the purpose of thermally insulating the exhaust pipe? Thanks! :-)
Not a lot really, it was just put on as a precaution, it does not really need it.
@@VintageRVAdventures Understood, thank you!
Thanks for the tips. You do realise that when you described the overall effect as being "half as quiet" you were saying it was twice as noisy? 😁
Lol.. Is that what I actually said, what a numpty am I .. Well spotted !
@@VintageRVAdventures: I recently bought one of these heaters and I've been binge-watching videos on the subject. "Half as quiet" at 08:54. 😉
Is this a brushless heater? Would a webasto, eberspächer, etc make any difference to a chinese on this? Not sure what fuel pump you´re using but ultra quiet ones are cheap these days ( + - 35 £) , they should fit to a chinese too?
Brushless motor? I am not sure to be honest.
Now, can you please update and let us know if the insulation caused the unit to run too hot or not? I’ve seen a lot of reviews of these sorts of heaters that they often overheat and throw error codes, and I’m wondering if the extra insulation caused any issues in real world use.
I can tell you the insulation did not at all cause the hot to run hot.
@@VintageRVAdventures, excellent feedback! Thanks for the speedy reply. 👍
add wood stove like forest forestry channel.
We would love to add one, but we just done have the right place for one.
Will your fuel pump overheadt?
It has not so far.
Any actual before and after decibel readings?
No, sorry Gary we don't have those readings.
@@VintageRVAdventures Iwas able to download
@@VintageRVAdventures There are several free decible meter apps that can be downloaded. They're a great tool for multiple applications like this.
Thanks Gary, I was not aware of this, thanks for letting us know.
I've seen examples where people wrap the exhaust, including the silencer. Some say it reduces the exhaust noise. Have you noticed any reduction in exhaust noise since adding the heat wrap ?
No, I wouldn't say wrapping the exhaust tube would make much difference. The main noise reduction is about surrounding the fuel pump, that is where the most noise comes from.
@@VintageRVAdventures Thanks Vintage. Using mine in a tiny house so the tick tick tick has not been an issue. After trying a couple of things, the best solution was to leave the exhaust as the maker intended. Unit works very well. Using a lot less firewood, and not that much diesel.
Get that a point I don't wanna hear about you doing your band or wherever you got. What about the watch caught the silent diesel heater so hard about this
My band? No idea what you are talking about lol.
You need to get the heat wrap wet first
That could be a good idea.
get a webasto silencer instead of the chinese muffler and it will get real quiet
Thank you
Don´t want to smartass,
but Alubuthyl sheets used for car hifi sounddeadening
would have worked even better than that soft self adheasing foam rubber!
That foam rubber material is rather more intended to serve as thermal insulation.
Your comment is appreciated. The sheet we had was used as we had it left over from a salvage Range Rover rebuild project.
Im no eu compliant never wanted such control use IMPERIAL ! do savie metric but why do U ditch Imperial??? Capisch
Not sure what that means, I will have to look back at the video to see if we quoted metric or imperial sizes. Here in the UK both are used, depending on one's age.
Half as quiet? No, twice as quiet
Lol... ytes that is true 🤣
Run it threw a can of crisco. Or bucket of water.
I am not sure how that would work out
For gods sake install an Electric pump and you Will thank me ......
It is an electric pump!
NO ITS A MAGNETIC PUMP/AND YES IT IS BUT ITS TOO NOISY.
IT presuraise the diesel so IT becomes a hase but if you godt another pump that is more silent that has the same presure you dont hear it at all i need to sleep
@@teisfussing3043 Its not noisy, we quietened it down using sound absorbent material in the video.
Or you can just use the heater and stop trying to fix something that can't be fixed.
Rude. But we havd fixed it 🤣🤣🤣
You need to replace that green fuel line, it degrades really quickly.
Any idea what diameter fuel line to buy? Or is the white rigid stuff typically the same size?
Thanks for the tip.
Try dynomat instead of that foam junk.
I will do some research on that product xx
wrapping the exhaust will cause it to overheat and possibly fail prematurely. it needs to dissipate its heat and not hold it in.
I have to disagree, based on experience. There have been no problems so far.
@@VintageRVAdventures you can also buy silent fuel pumps as well but I'm sure you know that already as well lol.
Sounds like your fan is hitting inside heater?? sometimes they push fan on shaft to far and they hit mine had this problem easy to fix your self
That is what happened when we first bought it, straight out of the box.
