Good Lord, the depth is incredible, you're like a surgeon delving deep into the body to see what's what, you would make a terrific forensic pathologist, an authority on getting all the answers. Unique, well done! and best wishes from Alan, in Norfolk, England.
I have the 2K.W. with metal case, and its not noisy. The criteria for me with which size to buy was how low it would go to maintain temperature, and it only uses 0.12 litres per hour on lowest setting. You need to buy the size that fits the space you are trying to heat. Also bear in mind that these heaters are made by different manufacturers to fit different price ranges.
@@David-vd7lv I was planning to have it in a cammper sprinter van conversation.... like everything in this project, a lot of comparisons, is needed. So I'm trying to save time by reading/watching reviews? But you do have a point, investment in quality and build/brand, should mitigate this issue.
@@David-vd7lv I can imagine that the sound from the motor is transferred to a flimsy plastic case... and a batter build with a sold case or better absorption padding between motor and case would be quieter.
I have mine in a campervan ,and with good insulation it heats up quickly, then just ticks over on low. This uses less fuel and electricity than switching it on and off.@@GSCt1000
Good video. Sounds like poorly lubricated and or poor quality bearings. I wonder if you install some NSK or similar quality bearings if it would quiet up.
It would be nice to know if new bearings solve the noise problem. My mother-in-law had a new gas fireplace installed, and the company charged a fortune for a (cheap?) fan motor that was this noisy. It would be interesting to know why the motor is so noisy. It was annoying that the fireplace company had no 'solution' to the noise issue. She sold her home, so now I can't explore that fan motor.
That would help, but I can only assume that the rotor is not balanced, causing the vibration. You could probably slap a little epoxy on it in the right spot and take care of the problem.
@@CanadienNortherner I've seen you comment on several people's posts trying to pimp out your ghetto swiss bearings. THIS JUST IN: Japanese bearings are better.
The "noise" problem with my 2kw heater is a bit different. There is no bearing noise. But it makes a sort of howling noise on low settings. I have to set it at or above 1.7Hz to stop it.
hi great video! Just wondering if its soot getting into that front bearing? Try popping the seal off the front of that bearing and flushing the grease out with isopropanol and test if its quieter then put a high temperature grease in there as It could also be heat transfer cooking the bearing oil? The ultimate solution could be fitting a ceramic bearing? All the best.:-)
How about grommets and a metal spacer as a new motor mount it would transmit less vibration to the bigger resonator make sure you use Loctite and then foam where the motor meets the plastic in reinforce it so it minimizes that vibration and I think that would reduce the noise cuz that's a heater I'm presently looking at right now and that's my thoughts of it when I get it first that's what I'm going to do is change the motor mounts
Nice one David , being a brushed motor it will be a bit louder than a brushless one , must be cost effective to use brushed motors in the building of these, ..??
Hi David, are these heaters suitable for using on their side so the exhaust and air intake can be routed out horizontally or will it affect it's running? Also, what are your thoughts on only having the exhaust routed to the outside and the air intake on the inside? I'm sure that heating efficiency would be better for my van if I wasn't sucking all the nice warm air in and then blowing it outside, but I'm considering it due to installation reasons, as I don't really want to cut a hole in the floor of my van.
Paul Bourne, they should be mounted so that the glow plug is not immersed in the fuel, so the glow plug should be on top, not sure if the side mounted would work as it should. Also the air intake is for the combustion not for hot air movement so this needs to come from the outside. The fan moves the internal air from one end over the fins/engine to heat the air and out the other end.
Hello mate just a quick question after 2-years of my Chinese I'm getting a lot of combustion noise even on tickeover and failing to start first time everytime I'm wondering whether my burn chamber has burnt through what are your takes on this I have changed my glow plug and mesh?? It's like a roaring gurgling sound only heard the intake under the van and you can hear it indoors ???? Keep up the good work always entertaining
Sigh! Just bought the same 2kw heater and mine has the same noise but louder, I can put up with it being like a jet engine on high but the low setting is really irritating...So the 3kw and above is the bigger design with the better fan bearings hopefully?
Any chance you have the bearing specs, numbers? Thinking I might order new quality bearings for mine and see if that helps quieten it down. Mine is the 5kw version, I'm guessing the same blower motor?
Great videos on this heater. Do you think there could be a way to retro fit a water heater onto it somehow? Maybe run the hot air initially thru a hot air to liquid transfer plate or somehow extend the metal housing of the combustion chamber into the bottom of a water vessel??
I would guess your best bet would be running the exhaust through some kind of heat exchanger, but you'd have to make damn sure not to introduce any leaks. CO-detector wouldn't be optional at that point.
I received my heater a few days ago. I'm still trying to figure out if it is the 2kW oder 5kW version (bought mine as 3kW which obviously does not exist as far as I know). What I noticed, especially on the lowest setting: You can reduce the noise a lot by putting the air inlet tube into place (next to exhaust tube). Mine came with the rotary knob controller. Can I simply plug an LCD controller instead, do you know if this will work?
Hi, first off all, thanks for your great and interesting wideos. My question is do you know how much heat that inner fan can handle? My plans is to make an heat exchange for exhaust pipe and intake pipe to feed in the extra heat in the intake off the heater. I don't care too much about the efficiency even if it should be better, my theory is that the heater wuld maybe be more stable with minimum power and it wuld be possible to run it with ewen lower power output. My current setup is with a webasto airtop 2000, that I bought second hand a couple of years ago and now it started to show symptoms off leaking exhaust in the van. My setup is a vito with good insulation and ewen when it's really cold outside, the webasto gives a way too much heat. When the webasto is ramping down to the minimum setting it should give something like 900w output and runs about 50% off the time when it's 0c outside. so it's all the time turning oon and after a while turns back oon... I ordered a couple off 2kw diesel heaters from two different places to get one as fast as possible and also to have one backup in case one gives up shortly or if I just manage to break one by tuning mistake. All the best and keep up the great work 👍
Helooooo David! Any thoughts on why a bottom shelf 2kW china heater (aside from it being bottom shelf!) would start and run for exactly 8 minutes every time and then switch off? I've tried all manner of tests. air intake strainer on /off. Fuel pump sitting right in a cup of diesel..K1 kerosene...a few tiny bubbles from the outlet of the pump but not many. A little white smoke at start but then it clears and burns. Glow plug goes off. Runs up normally for the green and yellow heat output bars but never hits red. Switches off reliably at 8 minutes regardless of pump Hz setting. It is a side exhaust mount with the glow plug up if that matters. Seems others have had that work....Any thoughts greatly appreciated!
Housing temperature sensor? The white ceramic bit on top of the heater. The inside portion can become detached and it is then no longer in contact with the housing and it reports a much lower temperature to the ECU. It might be seeing that as a failure to light, or a flame out and stops running.
@@DavidMcLuckie Thank you. That seems a likely culprit given that after 8 minutes and producing what seems like normal heat output, the display is still down in the yellow bars. I will dive in and see if the sensor is not as it should be. Much appreciate the reply! I'll post back when I know more.
@@DavidMcLuckie Well, either I'm really deficient in my setup or I just got a second bad heater from the same vendor. I did check the temp sensor in the first unit and it has no visible or installation defects. Second heater just fails to ignite, E10 error. The bench test setup has the fuel pump unmounted and eventually just sitting suction end in a jar of fresh K1 Kerosene. Maybe the fuel stream is weak without the pump body held firmly? Fuel is certainly being delivered. Even swapping brains out to the old heater didn't get either to fire. Going to return both of these and maybe try one from Maxpeedrods.
@@DavidMcLuckie Well, first my apologies for not watching your old videos more carefully and realizing the fuel pump will work just fine sitting loose. The second heater, which never once got into a full burn without an E10 error shutoff, donated a temp sensor to the first heater today and did manage to keep it going for 30 and then 60 minutes, albeit at a low temperature in spite of the max pump speed. 2 blue and 2 yellow bars followed after a time by reducing on its own to just 2 blue bars. Air in at about 46F and out at about 90F. All the while the pump was ticking away at its max 3.6Hz setting. Finally after the 30 or 60 minute mark it just said good night and shut off with an E8 error even though the fuel supply remained good. I'm thinking both of these came out of a batch that was either very poorly tuned or has some deformity in the combustion chamber. If the vendor doesn't want them back I'll bust in there and report back. Otherwise I'll take my refund to Mr. Maxpeedrod who seems to have good feedback.
How hard is it to take off the outer fan? I've just installed a 8kw and am getting a E06 error message. I opened up the case and the fan spins freely, but there's a decidedly low spot.
How the hell does that fan work?? the internal fan.. I don't see any air intake.. Does the center have openings to the front side? @ 4:06, I don't see any.. The hole in the case should be the output.. Where's it get input air from??
Could you use the ecu out of a chinese heat to run a genuine ebrspacher unit, i have an eberspacher with a dead ecu, do you think this would be posible ?
I wonder if its the bearings themselves that are out of spec that or the motor itself isn't balanced properly or at all. Though had the same buzzing recently with tumble dryer less than 10 months old, drive motor was buzzing, worse when hot, repair agent sorted it out, but not great given it was a decent brand of machine.
@@DavidMcLuckie Rotor, that was the word I was looking for and just couldn't bring to mind. Sounds like it isn't balanced properly, other option might be the motor shaft is out of round i.e. slightly ovalled, that or the bearings are just plain junk. Though an unbalanced rotor would make sense. Same way I work, dismatle stuff and try and locate whats actually causing the problem. Good video again
Access to a lathe.... He says, as a motor spins the fan on its axis. Get a sharp tool and a hoover and have at it. Edit: watches further, realises moot point.
Hi David I am trying to buy an 8kw heater (5 to 8kw) I know you have recommended Amazon in the past but can you ( or anyone else) recommend a supplier on Amazon please?
After 3 solid years, my 2kw motor has become very noisy, presumably worn out bearings. I hope it hangs in there until this upcoming cold spell is over 🤞 I now regret giving my emergency spare heater away to a friend 😂
Talking of noise, could you try two mufflers in line? There's two type straigth through and muffled (exit pipe different place). Be good t see if they coke up or if we can some without failing the unit. The main noise fromt he heater is the zorst, i want to keeo my neighbours happy... that pr i need to try sound deadening boards...
Mine makes exactly the same noise mine is brand new and is supposed to be 8k heater , my second one in 3 months I’m currently trying to to send it back and arguing over me having to pay courier charges I’ll never buy another the first one had a completely different problem but ended up being thrown on the tip due losing my temper now this brand new one is getting close to the same fate the noise is getting me down and being brand new I’m nearly a broken man dealing with those lot makes things a hole lot worse !! Btw I am told they have bearing problems hmm they ain’t kidding
China is an amazing country. Most people contact China to source the cheapest product. They will respond with bad products, made with cheap labour, and inferior materials.I have bought several machines from China. First steel roll forming machine cost me 25,000,as opposed to 125,000 from a European manufacturer,my advice when dealing with china,dont go for the cheapest product,offer them more,and they will deliver a high quality product,at the moment searching for campervan heating unit,they are all made in China,believe it or not
@@DavidMcLuckie Maybe if there are some reputable sellers that sell them, that offer good warranty and assistance. Because I so wouldn't want to play lottery by buying it from any Chinese seller (frankly dealing with defective units or units that don't work entirely properly - is probably worse than just paying for a Planar, Webasto or Eberspacher...🤷) I'm skeptical about Chinese clones... But I guess if one happens to get a good unit, that will work properly for years - it's worth it.
Hello I just bought a 8 kw heater, and when I first ran it there was a bad smell coming from the heating side. So I ran it for an hour and i can still smell it, and it was not getting any better, it smells like burning wires and rubber. Just wondering if anyone has came across this problem yet with there diesel heater thanks.
Yes they are waaay quieter. I'm a truck driver and use them every day pretty much. No problem what so ever sleeping with one barely 2 foot from my head under the bunk. These Chinese ones are clearly cheap shite.
Thanks for the info - I suspected as much. however, it's the only thing that the expensive ones seem to have over the chinese ones, which are far from shite [I have one] - they're just a little noisey. @@86SVA
A word of warning if you are thinking of buying the 8Kw version don't. Another youtuber tested one and they are 5Kw heaters being sold as 8Kw heaters, all he got at maximum was 5.26Kw. If you're curious here is the video th-cam.com/video/Dw4BjcTnvzE/w-d-xo.html
I don't put much trust in any of those numbers. But there is a physical size difference between the two sizes of heater I have. For the larger I have seen it advertised as 5, 8, 10 and 12kw.
looking around I found on Amazon a replacement fan motor for the ESPAR heater. It might be a suitable replacement for that noisy dc motor www.amazon.com/Eberspacher-Combustion-Blower-Airtronic-Replacement/dp/B073W6XX95
Looks a lot like this one - www.ebay.co.uk/itm/Airtronic-Car-Motor-Blower-Combustion-Air-Fan-12V-For-Webasto-Eberspacher-Heater/153061406608?hash=item23a32bb790:g:UaoAAOSwkSxbIh1g:rk:18:pf:0

I'd also get Swiss ceramic bearings . They also run dry , no need for grease, or oil and they're very quiet .
Dry bearings, flick the cover off slop some grease in or remove bearings and go get something of better quality of bearing

That is exactly what I do when overhauling machines. big or small. Factory bearing are notoriously poorly lubricated.

I've had that on a few heaters. As you've discovered it's a settings issue. The air fuel ratio isn't quite right and it makes that noise.
I fitted s 2kw nearly 4 years ago. It's still as quiet as a mouse, despite a lot of use.
@A Mercer they're all the same....
Sounds to me like the motor has been assembled incorrectly , the armature is rubbing on the stator at the rear of the motor.
Very thorough! Good teardown :)
Had a 5kw that went crazy loud from being shot (as in installed with either worn or dry bearings), the internal impeller was rubbing the casting!
2KW is the size I need but the 5KW are cheaper I wonder if they're louder?
which didyou get, I'm looking for a motor for my civic, wonder if 5KW is overkill, but don't want the extra noise.
Encase it in a noise insulated box, obviously not blocking the inlet and outlet?
Vibration damper for the motor? Is that at all possible? Like when car manufacturers jam in a foam piece to stop a dashboard rattle.
Yes, but I think it's the motors rotor that is unbalanced.
Interesting the second fan is a vortex compressor not a conventional fan - higher pressure
Super Video (as always) you could be very valuable at sea on a boat, life savingly valuable ! :-)
The pump though! Thats the noise I can't tolerate!
Someone said there is new almost silent pump, but I haven't looked into it yet.
It seems you've got one there with a noisy motor bearing. Mine is quite quiet on low, so quiet i can still hear the exhaust outside.
I've tried taking the bearings out and re-greased them. But what I did notice was how unbalanced the rotor was. This might end up being another video.
Having used them a bit more now, would you recommend the rotary knob controller over the LCD one still?
If you don't need any of the things the LCD one does, like on off timers or having a set temperature then all you need is the rotary one.

As Bill has said people have run them side on as long as the glowplug is at the top. But you'll still need to make a hole for the exhaust somewhere.
have you tried the 5kw heater that has the fuel tank and controls all in one container?
The motor has to be isolated somehow maybe O-rings im still fiddling with the fan motor and the aluminum housing to isolate the vibration

Good video keep them coming.
hi dave good video test the Eberspatchers at 6
times the price to see how noisy that is ?
I am not rich enough to buy an Eberspatcher just for testing. :)
Great video.
I'm going to box mine up . So I'd say will be quieter and I could glue 10mm rubber on walls inside the box. or 15 mm marine plywood.
Hi David
I am trying to buy an 8kw heater (5 to 8kw) I know you have recommended Amazon in the past but can you ( or anyone else) recommend a supplier on Amazon please?
Hi will the unit run with the flue out from the side or can it run with the flue upwards, as I would like to fit one with the flue out of my roof
It will run on its side as long as the glowplug is on the top side.
Why you didn't try to disassemble the motor?
Sure did - th-cam.com/video/egthci7q9Ag/w-d-xo.html and th-cam.com/video/HhE9rlcaT0s/w-d-xo.html
Had bearings in these heaters that had no grease in them
Thinking of get one for my van which is Vw caddy because the heater is shit which one should I get buddy ?
From the experience of buying two heaters, I'd go for the 8kw. Same price as the 2kw.
Bearings on that motor probably installed with a hammer on a Friday.
fan balance is causing the bearing noise.
It's not, but thanks.
Can you give part # and where you got bearings
5x16x5mm bearing size - 625Z or 625ZZ. I got mine off eBay.
After 3 solid years, my 2kw motor has become very noisy, presumably worn out bearings. I hope it hangs in there until this upcoming cold spell is over 🤞 I now regret giving my emergency spare heater away to a friend 😂
My controller keeps flashing 888 ? whats that mean ?
888? That I've not seen before.
@@DavidMcLuckie I have come to the conclusion it s just saying combination chamber not lit as it seems to work fine :)
Talking of noise, could you try two mufflers in line? There's two type straigth through and muffled (exit pipe different place). Be good t see if they coke up or if we can some without failing the unit. The main noise fromt he heater is the zorst, i want to keeo my neighbours happy... that pr i need to try sound deadening boards...
I tried 2 silencers and it came up with error after a little while, removes and it's been fine ever since. Don't think it liked the restrictions
@@skankhunt-43 same.
For sale - Silicone Spatula. As new with label.
Mine makes exactly the same noise mine is brand new and is supposed to be 8k heater , my second one in 3 months I’m currently trying to to send it back and arguing over me having to pay courier charges I’ll never buy another the first one had a completely different problem but ended up being thrown on the tip due losing my temper now this brand new one is getting close to the same fate the noise is getting me down and being brand new I’m nearly a broken man dealing with those lot makes things a hole lot worse !! Btw I am told they have bearing problems hmm they ain’t kidding
You said weebly wobbly. You must be a Are You Being Served fan as well.
what is it with china, why can they make most things; but seem to be incapable of making a bearing.
Lower manufacturing costs, less quality controll equals cheaper items!!
China is an amazing country. Most people contact China to source the cheapest product. They will respond with bad products, made with cheap labour, and inferior materials.I have bought several machines from China. First steel roll forming machine cost me 25,000,as opposed to 125,000 from a European manufacturer,my advice when dealing with china,dont go for the cheapest product,offer them more,and they will deliver a high quality product,at the moment searching for campervan heating unit,they are all made in China,believe it or not
Could you have wrapped the motor in a thin silicon layer or applied liquid silicon into the casing holding the motor?
Put a rubber band under where it mounts contact base should help alot.otherwise find a brushless
Will need to see if I can get a rubber washer or washers as it mounts end on.
Why they have used a brushed dc motor ill never know.
Because it'll be cheap. :)
the motor has a bad bearing
Is this a Chinese heater? Are they worth buying?
Is it. And they are.
@@DavidMcLuckie
Maybe if there are some reputable sellers that sell them, that offer good warranty and assistance. Because I so wouldn't want to play lottery by buying it from any Chinese seller (frankly dealing with defective units or units that don't work entirely properly - is probably worse than just paying for a Planar, Webasto or Eberspacher...🤷)
I'm skeptical about Chinese clones... But I guess if one happens to get a good unit, that will work properly for years - it's worth it.
### ... I think your motor has a bent driveshaft ?
It's either bent, or badly balanced.
Webastos and espacer ! Are the same noisey
Hello I just bought a 8 kw heater, and when I first ran it there was a bad smell coming from the heating side. So I ran it for an hour and i can still smell it, and it was not getting any better, it smells like burning wires and rubber. Just wondering if anyone has came across this problem yet with there diesel heater thanks.
There shouldn't be a smell like that.
Replace the whole thing with a brushless RC motor.Better power efficiency also.
Can you get a brushless motor as a direct replacement?
both bearing in my park heater were dry no grease "OOPS"
hi m8 is there a clearence for burner fan
I pushed mine on until it was just not touching.
@@DavidMcLuckie thanks m8 love your vids
I wonder - are the Webastos/Eberspatchers quieter?
Yes they are waaay quieter. I'm a truck driver and use them every day pretty much. No problem what so ever sleeping with one barely 2 foot from my head under the bunk. These Chinese ones are clearly cheap shite.
Thanks for the info - I suspected as much. however, it's the only thing that the expensive ones seem to have over the chinese ones, which are far from shite [I have one] - they're just a little noisey. @@86SVA
@@harmonicresonanceproject jims raging he spent 1k on a quiet heater lol .. on here watching videos of "shite" .. sure jim !
@@katoomaheaven sorry to dissapoint you but I don't pay for heaters put in my employers trucks. They're standard fitment.
@@86SVA 😂😂😂
My 8kw one is way too noisy looks like il mount it on the outside of my shed in a box.😱
Which is actually a very safe way of installing it as well.
A word of warning if you are thinking of buying the 8Kw version don't. Another youtuber tested one and they are 5Kw heaters being sold as 8Kw heaters, all he got at maximum was 5.26Kw. If you're curious here is the video th-cam.com/video/Dw4BjcTnvzE/w-d-xo.html
I don't put much trust in any of those numbers. But there is a physical size difference between the two sizes of heater I have. For the larger I have seen it advertised as 5, 8, 10 and 12kw.
you should have greased the bearings of the motor
Tried that first.
The noise is to let u know its working so stop complaining
There is that.
@Kamper Ken covid vaccine is t fault
Chinese heater, Chinese bearings. I reckon if you changed the bearings it would be quieter. ;)
???? Cant you fit a top quality brushless motor ..
If you can find a 2 wire brushless motor of the same dimensions then it should be possible.
I think it's just noisy motor
Noisy is ok if it keeps ya warm
Why don’t you put the to this item, you might get few cents every click!!!
I thinking this as a medium turbo reactor lol ok i go out 》》》EXIT《《《
What kind of accent is that?
I think he sounds like he is from Scotland
Интересно,но нихрена не понятно
Well it's not Scottish so you know it's cr@p !
It’s the old you get what you pay for I think.
looking around I found on Amazon a replacement fan motor for the ESPAR heater. It might be a suitable replacement for that noisy dc motor
