I work in quarry’s driving excavators… minus 13 outside was my coldest temperature… my Eberspacher was a 4 kilo heater… i ran that at 50% heat output…. My Motorhome was at 18 inside… beautiful… off of my 500 jackery… 8 hours running…… take it to my machine and charge…. Back again the next day…. Lovely
Don, another valuable video. I have a few of these heaters, and the core heater seems reasonable, but the accessoires are near junk. Case in point is the fuel filtor. To me it looks like it will fail soon, i just throw them out right away. Having one of those fail inside a RV or Boat, will be a stinky mess. You can get good automotive ones cheap. Thanks again, Steve
Hi Steve, Yes, agree with you there. That's where they save their production costs. The burners themselves are pretty bulletproof.... Although I have been running this for a year now without any problems, but once I start tinkering again, no doubt I'll upgrade these accessory parts. ATB, Steve
Great input, with the price of bottled gas about to go through the roof, this is surely the way to go for us MH owners who use our vehicles all year around.
@@TheWrinklyNomads Eugene, Oregon. Some re-fillers are out of propane. Some exchange-cages have only empty bottles. . I finally found exchange bottles in a closed garden-supply area of a Fred Meyer grocery store... dated mid-2015. . An aside: Southern California railway yards, entire trains of boxcars, emptied, vandalized, waist-deep discarded cardboard boxes. Is this is your neighborhood, too?
I have seen many of your videoes, very short and super informative. 👍👍 Much better as many other videos, that takes 15-20 minutes, often repeating them self several times, ( pretty annoying) maybe they just like to hear them self talking. 😃
thanks for the info. I want to do a permanent mains powered setup with enogh battery for 24 hours in case of power cut. The power drop should set off the automatic shutdown sequence of the heater in case the power runs out completely. I want minimal effort, but I will make a nice neat setup. Can you recommend a suitable battery and charger combination? Or maybe an off the shelf UPS unit? I live in New Zealand.
I am shopping for a heater and your video caught my eye, i like the testing aspect. It makes it more enlightning to see the actual numbers as opposed to companies selling their products. My question is ( hopefully its not to dumb) i have noticed that many videos show the controller mounted away from the unit, is this standard on most heaters or is it something that you have to rewire? Thx Again enjoyed your video very much Cliff
Hi Cliff, These heaters normally come with the controller on a long lead, about 2mtrs, so they can be positioned more conveniently away for the heater. Hope that helps 👍
2003, we converted a 1996 Ford CF8000 to our concept of an ExpeditionVehicle. Our interior is 7w x 12l x 7h, about 700cf. Our windows are stand-still house 3612, three feet wide by a foot tall, dual-pane sliders. We mounted our windows at eye-level while standing inside... about eight feet above pavement. . Nearly two decades full-time live-aboard, we are considering a diesel forced-air furnace, retiring our ancient propane Wave 3 catalytic heater. . Our problem: Our AGM bank is equally ancient, so running a 12vdc-dependant appliance requires significant modifications to our foundation...
I found the diesel heaters to be a good upgrade over propane and more efficient. Once upto temperature they really don't use much power at, but if your AGM's are near the end of their life I would upgrade to Lithium. Still got plenty of like in mine, but definitely the route to go. safe travels, Steve
For those who wan't to run it of a power pack Bleu Jetty / Jackery and so on . The chance of success depends on the amp draw , some glow plugs are set to 75 watt and some to 95watt . Even 75 watt plus motor and pump will be at the max of the 12 volt socket . So not advised .
@@TheWrinklyNomads going to buy a diesel heater and 20ah lithium battery, now I can go camping for 2 days and not worry about killing my car battery. Should be enough for 2-3 nights depending on how heavy I use it.
This seemed to be a very helpful video, but then it seemed that the information you give have few similarities with data that I get from my heater. Maybe because of misunderstandings on my part. What does not seem to correlate at all with my heater is the ”5.9 watt”. When running on the lowest setting and not being in start up mode, my heater uses 19 watts. When starting, for a short period of time it uses more than 100 watts.
Hi, I think you have slightly got your electrical units mixed up.... easily done! Your readings are in Watts, I have measured in Amps. Your running usage of 19 Watts is the equivalent to 1.5 Amps and the other reading of 100 Watts is still only 8.3 Amps. These are about the same as the readings in my tests. So all ok 👍
All i need is a approximate watt hour usage for this thing lol.. if i understand this correctly for a tent situation id run it on low for 8 hours and that would leave me running roughly 200 watt hours? Or 80 ish lol oh my goodness this rabit hole never ends 😂
interesting that is measure o.oamps before you started it as mine has flattened fhe battery before from the screen when left on. I learnt to pull the fuse if im not using it for a while
Hi Luke, Yes, the LED controller will draw a very small amount of amps, but the meter I use is not highly sensitive and wont read that small amperage draw, hence the starting zero... When I'm not using the van for any period of time I always pull the fuse on the unit as well. ATB, Steve
I have just set one of these up for Roof top tent camping. Was hoping my 80Ah Agm would be happy to run this all night without using upto 50% .. I think i should be ok. Haha. Thank you for this video
why one night? Hes got 80Ah where 50 percent is 40aH. According to the consumption that you have measured it should run 40 divided by 6 Ah which is 6 nights. Am I missing something here? Thanks @@TheWrinklyNomads
Hi, No your not missing a thing! Your exactly right.... I have no idea why I have said it 'just about' run it? It'll probably run even longer.... Thank you for pointing that out 👍 ATB, Steve
Thats not alot at all im impressed, mine gets delivered tomorrow its for my transit connect to defrost in the winter etc, also i was concerned about using the engine battery for a morning warm up, and wake up to a dead battery. But i think i will be ok 👍🏻
The display / controller on these heaters do use some power even when the unit is switched off. It's worth isolating the heater from the battery when it's not being used.
I will have on my microcamper a 300w solar panel,150ah gel battery, renogy mppt dc-dc battery charger , pure sine inverter 1000w ,one fridge and this diesel heater. I think in winter ,the power will not be a problem. Anyway in the summer ,the heat is deadly. Any solution for the summer 40-45 degrees celsius hell?😊
Please can you add the pumping rates for these phases. Presume the pump is the standard 0.022ml/stroke? It would be useful, in particular, to know the minimum flow rate for your machine, hence an idea of the heating power output. Apart from that a good, clear video. Thanks.
Hi Richard, Thank you. I wasn't really concentrating on fuel pump rates for this video, however I do have the pulse settings to: 2.2Hz min and 5.5Hz max. But running on the temperature control setting (which I used) rather than Hz, I think the pump will tend to run on max or min during a heat up phase or min when in maintenance phase...? As for heat output, running at max. fan and pump did give me 93 degrees C at the vent outlet, so I suppose I could use it to gauge the maximum power output.? ATB, Steve
Vevor has 12v 15 Amps on the label of its heater. I was using an Xbox 360 power supply which has 9.5 amps, it ran great for quite a while, then I got some dirty diesel by mistake used a can that had some stuff at the bottom and stated getting error messages. Then white smoke. Since then, I cleaned it all totally. Glow plug fine mesh atomiser OK. Then it gave a fan error I stripped the fan found the carbon was sticking fixed that and tested the motor seems fine but still same error. Now I sent for a new fan motor to see if that stops the error message. These heaters have an awful lot can go wrong. This heater was a Lemon from the start. Seems like it will never run right.
I have had my two at home and on my boat for over two years and have not had any issues at all. Dirty diesel is never good. Make sure the two cables are in the correct ports on the pcb. If you put two of them in the wrong holes it will throw up that error code...
Just a small tip: If you do something like this again, use Wh instead of Ah. I know in the RV space people love to talk about Ah, but it is not the right unit. I saw in your video that your measuring device also showed the Wh, which is a unit of Energy. And therefore usable no matter the voltage. If someone has a 24V system, they will only use half the Ah you mentioned, but the same Wh. Small detail from a overly obsessed engineer 😘
@@TheWrinklyNomadsbatteri3s have 12v and consumption is always a c20 of the amp hours of the amperage max of the battery... If i asked how big is your battery it will always be a 80ah or 105ah say... When working out you battery needs you always say I have a 30watt light system, and then end up converting that to amps as that's what determines the battery drain and more importantly what your needs are for charging the battery to keep it in a good condition.
Ok, so my idea of connecting a 12v diesel heater with a 12v fuse block thats also connected to lights, plugged to a 12v car plug into power station will work. Needed to know how many amps of power a diesel heater used before I decided to go with my idea, not sure if anyone else tried what I'm gonna do but I doubt it hasn't been thought of lmao Good video thanks.
@@TheWrinklyNomadstest carefully - the problem might be if the power station decides to stop operating as the glow plug has been heating things up - so you’ll need to be sure you’ve got that covered I guess?
Super helpful! I was wondering if a 2nd battery is needed for just an overnight use, looks like it would not use even 10% of a battery during all night sleep. The heater I'm installing is a smaller, 2kw unit, so I guess it would use even less power.
@@Chadlechon I went with not having a 2nd battery and my 72 Ah starter battery of unknown age had no issues with starting and running it for couple of hours at full power. Later the car has restarted with no issues (5.7 small block)
@@Chadlechon As a backup I want to assemble a step down converter that would allow me to boost the car battery from a 18V power tool battery, so that even if the car has trouble starting in the morning I'd still have a means to revive it.
Hi, i searched for something and this, your vid came up, very good so I’ve subscribed. Can you advise: I have a campervan with a 110ah wet cell battery. My diesel starts well, goes through the warm up process but before it gets chance to progress, after about 5-6mins the battery protection kicks in 😢 Would you say that’s correct for size of battery, is the battery needing replacement? Also, if it is correct and therefore designed mire for EHU, can you recommend a battery so i can use off grid please? Tia!
That is a bit strange. Wet cell gives about 50Ah available which is plenty for start up and you shouldn’t be getting problems. Is there anything else running at the time? You’re battery voltage may be dropping as well, but that would give an error code E01. Alternatively true another battery that know is good. Any lithium over 100Ah will run it 👍🏼
they are all the same size. clones of a 2kwh german heater. it you do the math on the fuel consumption and BTUs it proves it they all output between 2-3kwh
@@fathergratwick but the 2kw is physicaclly smaller than the 5kw, i have both. Although i did turn the 5kw one down to 2kw settings, but the max on 5kw is definitely brings the temperature much faster than the 2kw one.
@@roadbiker8333 yes im aware they make smaller version too thanks for pointing out my error. I just did some quick research the larger version is a direct clone to the original german Eberspacher "D4" 4kwh heater they copied.. The smaller one is the D2 2.2kwh if you search here you will see multiple test videos where they break down the btus in the fuel consumption and all these chinese heaters ive seen tested were below 3kwh in output regardless of setting and fuel pump or advertised size. The whole 5-8kwh thing is just marketing exaggeration to sell like they do with batteries. The patent ran out on the german heater so the chinese cloned it exactly.
This may be addressed elsewhere in the comments. Just bought my first diesel heater. Honestly should’ve maybe researched more. I noticed your control is way more advanced and has many more functions than mine. What brand/model of heater is this? Thsnks
Hi. Thanks for the informative video. Ive just purchase a 8kw all in one unit. Its run via a new 12v 46Ah battey with a brand new smart 12v charger/trickle charger. All is well for about 40 mins then the unit stops showing Error code E 2..... Any ideas what the problem is?....Bad battery? Would I be best changing to 240v/12v transformer, cheers. Steve
Interesting…. I believe a E2 error can be over voltage or no flame. Judging by the power supply you have is probably flame related. Maybe check all the fuel lines for kinks and the air intake or exhaust is not blocked. Or ask on the Facebook diesel heater page. That’s very helpful 👍🏼
Thanks Steve, I think I would still keep with the 5Kw. Would warm up the smaller volume of air quicker, which would be better. Better to have too much than too little eh.. ATB, Steve
Great vid very informative 👍 Given these use a fair bit of amp when shutting off what would happen if say the heater was left on and the battery run out of power ?? Thus the heater not been able to pull enough amps from the battery to initiate a shut down mode . Or does it have a cut off to save it from doing that ? Does it shut it self off when the power gets really low ? Or does it just keep going until Either the battery dies or someone initiates the shut down sequence ?? If it just lets the battery die without shutting down correctly then that is likely to cause issues both to the heater and persons using it
Hi, There is a low battery error code that will show on the controller to indicate the power source is low. If the battery gets below a certain point it will then initiate a safe shutdown. However, if there is a complete power loss, that could cause overheat damage to the unit and melt the wiring etc.
Question about the thermostat - if you set to 21c, the heater goes to full power, reaches room temperature of 21c, then throttles down to its lowest setting. I assume when the room temperature drops, the heater will throttle back up to full power and go through the same process. Do you set the low temperature for the heater to ramp back to full power? Does the heater thermostat setting work independently from the heater level setting (1 to 5), if you set to level 3 does the heater continue to run at that level till you shut it down. Can the heater be mounted vertically, with the hot air outlet on the top?
Hi Yes, the thermostat setting works the same way a household one does. Set it to 21c and it'll throttle up and down to maintain that specific air temperature. You can't set a low thermostat setting, it'll just ramp back up when it drops below the temp you have it set at. If you set at level 3, it will stay there regardless of air temperature around it. It just ticks over at that level. I believe there are some units that can be mounted vertically, but don't quote me as I'm not 100% sure. Best to double heck with the manufacture's I suppose. ATB, Steve
Hi Martin, Yes, these little heaters are quite efficient with their power requirements. If you’ve got a fixed power supply then that’s ideal 👍🏼 ATB, Steve
I started my heater up connected to a computer power supply rated for 12V at 11 amps, it died in the first 30 seconds of run time. I'll be getting a motorcycle battery when I can get to the store.
@@TheWrinklyNomads I'm curious why in your video, the amps never even got above 8 amps, how come the 11 amp power supply he mentioned, wasn't sufficient enough?.. 🤔 Thanks 👍
Thanks for this mate, I've searched the web for this information and found nothing. Your video has all the answers I was looking for. Top man 👍 Ps, I.ve tried finding the meter you are using cuz I like the way it measures. Any idea where I can get one from please?
Brilliant and good data !v Lower power consumption than I guessed. I'm curious to know what the overall efficiency is for the diesel heater with regards burning the diesel ?
Hi, Yes. they are pretty efficient little units eh 👍 If you want to know exact fuel burn rate and see the efficiency, I have a full video on the here: ruclips.net/video/z8SkKAlOAxU/видео.html ATB, Steve
Great video, so 6.5amp hours is what it would take out of the battery, in recharge words, 6 hrs back on the charger to bring the battery to 100%? Or am I calculating that wrong? How do you convert 6.5 amps from a battery to volts from a battery?
Hi Chris Doesn’t quite work like that, but long as you can put back the 6.5amps used you should be fine. This will all depend on you charge amount any charge time. You will find it varies considerably on what battery and recharge system you have. ATB, Steve
I notice your power station has a DC output 10A max. My diesel heater, which I think is the same as yours, calls for 15A. Looks like you pulled 12amps periodically and the power station handled it. There are lots of threads on line cautioning against having too low max Amps input for these heaters, but the power station options become very limited beyond 10A. Thoughts?
I tried running a heater like this off a jackery 1000. But the high startup current draw overloads the 12v output from the thing. I might need 240v to 12v transformer capable of handling the startup current.
I got exactly the same problem on an Anker Solix C1000. The startup kicks in the overload protection. But there are plenty of RUclips videos where people are running diesel heaters with the 12V Car outlet of power stations....
Just discovered your channel and have found what I've viewed thus far. When you mounted the LCD/control panel, did you solder in additional wiring length or were you able to find a premade extension or at least the same quick disconnects to make your own? --I want to relocate my LCD and capable of soldering in longer wiring but would prefer finding extension cable w/ the quick disconnects on both ends. Thanks!
Hi Evan I didn't add any extra cable to the LCD controller to burner unit as it wasn't needed in my case. I think it was already about 5 foot plus long.
I'm terrible with electrical measurements. Most batteries are 12v output and measured in Wh. How do this data compare to that and how big of Wh battery would I need to run this for several nights?
Hi Kade, The controller will probably show a low voltage error with just 12v, especially on start up as it it also discharges the most at that point. By the way, battery output is measure in Amp Hours. The start up and shut down procedure are where you get maximum draw, anything up to 10Amps. At this part in the video I show Amps used for a 10hr period. ruclips.net/video/puvd9Z8zJFY/видео.html But realistically, a minimum of a 12v 50Ah battery will do it 👍 ATB, Steve
Hi, I want to remove the old gas heater in my motorhome. It doesn't work, so I'm having a diesel heater fitted. Do you have a tutorial for when you removed yours (if you did that is). I'd like to use all of that area for storage now. Love your videos, thanks 😁
I've got Truma Gas Heating using non refillable bottles. The price of bottled gas has gone through the roof. I have no concerns over battery capacity but would you say these diesel heaters are cheaper to run in fuel costs than bottled gas? (2 × 6kg in my van)
Electric power demand is the same for all of these heaters. Obviously a smaller unit takes longer to heat a given space, but battery usage per minute is the same.
@@AnthonyP-zi6zpthe fan, circuit board and pumps are all the same so the electric use is the same, the 2 kW is smaller than the 5kw and 8 kW which are the same heater. The electrical use is the same across the board.
@@johnsader8811 the heater draws a small amount of current to power the lcd display screen. It is minimal however. Best thing if off grid is to isolate all electrics to ensure there is zero draw. Ensure any switch is rated to 15amps as the unit will draw around 12ish amps on start up...

My Motorhome was at 18 inside… beautiful… off of my 500 jackery… 8 hours running…… take it to my machine and charge…. Back again the next day…. Lovely
Yep, that's the way to do it.👍
Pretty straight forward, and chock full of good, clearly presented info
👍🏻👍🏻
Thank you Tomas,
Glad it was helpful for you.
ATB, Steve
Thank you so much for the information. You answered all of my concerns regarding power usage.
Don, another valuable video. I have a few of these heaters, and the core heater seems reasonable, but the accessoires are near junk. Case in point is the fuel filtor. To me it looks like it will fail soon, i just throw them out right away. Having one of those fail inside a RV or Boat, will be a stinky mess. You can get good automotive ones cheap.
Thanks again, Steve
Hi Steve,
Yes, agree with you there. That's where they save their production costs.
The burners themselves are pretty bulletproof....
Although I have been running this for a year now without any problems, but once I start tinkering again, no doubt I'll upgrade these accessory parts.
ATB, Steve
Great video sir. Providing the value no one else was 🙂
Great input, with the price of bottled gas about to go through the roof, this is surely the way to go for us MH owners who use our vehicles all year around.
Agree with Stan...
Bottled gas is just going stupid now.!!!

Thank you for the vid . My 2x110 ah barber's with solar charging should be great thanks
thanks for the info. I want to do a permanent mains powered setup with enogh battery for 24 hours in case of power cut. The power drop should set off the automatic shutdown sequence of the heater in case the power runs out completely. I want minimal effort, but I will make a nice neat setup. Can you recommend a suitable battery and charger combination? Or maybe an off the shelf UPS unit? I live in New Zealand.
Thanks for the informative video. This answered my exact question.
I am shopping for a heater and your video caught my eye, i like the testing aspect. It makes it more enlightning to see the actual numbers as opposed to companies selling their products. My question is ( hopefully its not to dumb) i have noticed that many videos show the controller mounted away from the unit, is this standard on most heaters or is it something that you have to rewire?
Thx Again enjoyed your video very much
Cliff
Hi Cliff,
These heaters normally come with the controller on a long lead, about 2mtrs, so they can be positioned more conveniently away for the heater.
Hope that helps 👍
Excellent video, thank you!
Thank you 👍
That's some great information really helpful Thanks

Great informative delivery. Thanks AJ
Brilliant instructive video. Exactly what I wanted to know. Thanks!
2003, we converted a 1996 Ford CF8000 to our concept of an ExpeditionVehicle.
Our interior is 7w x 12l x 7h, about 700cf.
Our windows are stand-still house 3612, three feet wide by a foot tall, dual-pane sliders.
We mounted our windows at eye-level while standing inside... about eight feet above pavement.
.
Nearly two decades full-time live-aboard, we are considering a diesel forced-air furnace, retiring our ancient propane Wave 3 catalytic heater.
.
Our problem:
Our AGM bank is equally ancient, so running a 12vdc-dependant appliance requires significant modifications to our foundation...
I found the diesel heaters to be a good upgrade over propane and more efficient.
Once upto temperature they really don't use much power at, but if your AGM's are near the end of their life I would upgrade to Lithium.
Still got plenty of like in mine, but definitely the route to go.
safe travels,
Steve

For those who wan't to run it of a power pack Bleu Jetty / Jackery and so on . The chance of success depends on the amp draw , some glow plugs are set to 75 watt and some to 95watt . Even 75 watt plus motor and pump will be at the max of the 12 volt socket . So not advised .
Very true there Paul...
Also don't plug into the the cigarette outlet on a portable power pack. I was cause overheating.....
If you have a 8-10 amp 12volt socket you will be fine. It’s max firing up the glow plug is about 10amps then throttles down to around 2 amps.
Great video. So the answer is: naff all really. That's reassuring. Especially if you plan to run one of these off a car battery (~60ah).
Thank you for watching.
Make sure the voltage doesn't go low and you have over 10A available and you should be ok.👍
This is awesome! Well explained video
Glad you liked it! 👍🏼
@@TheWrinklyNomads going to buy a diesel heater and 20ah lithium battery, now I can go camping for 2 days and not worry about killing my car battery. Should be enough for 2-3 nights depending on how heavy I use it.
This seemed to be a very helpful video, but then it seemed that the information you give have few similarities with data that I get from my heater. Maybe because of misunderstandings on my part. What does not seem to correlate at all with my heater is the ”5.9 watt”. When running on the lowest setting and not being in start up mode, my heater uses 19 watts. When starting, for a short period of time it uses more than 100 watts.
Hi,
I think you have slightly got your electrical units mixed up.... easily done!
Your readings are in Watts, I have measured in Amps.
Your running usage of 19 Watts is the equivalent to 1.5 Amps and the other reading of 100 Watts is still only 8.3 Amps.
These are about the same as the readings in my tests.
So all ok 👍
This guy is awesome. His installs, trials, and explanations are really helpful.
Hi Ed,
Thank you for the kind comments.
I appreciate that.

But he doesnt tell us if he is using a 2k 5k or 8k diesel heater
Very useful info, i will use this on my sailboat. Uses a lot less power than i anticipated, you earned a subscriber :)
!
Glad it helped and yes, they are surprisingly economical.
Thank you for the sub 👍
ATB, Steve
All i need is a approximate watt hour usage for this thing lol.. if i understand this correctly for a tent situation id run it on low for 8 hours and that would leave me running roughly 200 watt hours? Or 80 ish lol oh my goodness this rabit hole never ends 😂
interesting that is measure o.oamps before you started it as mine has flattened fhe battery before from the screen when left on. I learnt to pull the fuse if im not using it for a while
Hi Luke,
Yes, the LED controller will draw a very small amount of amps, but the meter I use is not highly sensitive and wont read that small amperage draw, hence the starting zero...
When I'm not using the van for any period of time I always pull the fuse on the unit as well.
ATB, Steve
I have just set one of these up for Roof top tent camping. Was hoping my 80Ah Agm would be happy to run this all night without using upto 50% .. I think i should be ok. Haha. Thank you for this video
Roof tent..!!!
Interesting 🤔
Yeah, your battery should just about do it for one night.
ATB, Steve
why one night? Hes got 80Ah where 50 percent is 40aH. According to the consumption that you have measured it should run 40 divided by 6 Ah which is 6 nights. Am I missing something here? Thanks @@TheWrinklyNomads
Hi,
No your not missing a thing! Your exactly right....
I have no idea why I have said it 'just about' run it? It'll probably run even longer....

@@TheWrinklyNomads thanks the reply, arrived and fitted last week, works a dream, the jubilee clips are crap though 😂
The display / controller on these heaters do use some power even when the unit is switched off. It's worth isolating the heater from the battery when it's not being used.
Yes, but be careful that it's not accidentally turned off when running the heater.
@@TheWrinklyNomads Indeed so.

Thank you sir !
Please can you add the pumping rates for these phases.
Presume the pump is the standard 0.022ml/stroke?
It would be useful, in particular, to know the minimum flow rate for your machine, hence an idea of the heating power output.
Apart from that a good, clear video.
Thanks.
Hi Richard,
Thank you.
I wasn't really concentrating on fuel pump rates for this video, however I do have the pulse settings to: 2.2Hz min and 5.5Hz max.
But running on the temperature control setting (which I used) rather than Hz, I think the pump will tend to run on max or min during a heat up phase or min when in maintenance phase...?
As for heat output, running at max. fan and pump did give me 93 degrees C at the vent outlet, so I suppose I could use it to gauge the maximum power output.?

Vevor has 12v 15 Amps on the label of its heater. I was using an Xbox 360 power supply which has 9.5 amps, it ran great for quite a while, then I got some dirty diesel by mistake used a can that had some stuff at the bottom and stated getting error messages. Then white smoke. Since then, I cleaned it all totally. Glow plug fine mesh atomiser OK. Then it gave a fan error I stripped the fan found the carbon was sticking fixed that and tested the motor seems fine but still same error. Now I sent for a new fan motor to see if that stops the error message. These heaters have an awful lot can go wrong. This heater was a Lemon from the start. Seems like it will never run right.
I have had my two at home and on my boat for over two years and have not had any issues at all. Dirty diesel is never good. Make sure the two cables are in the correct ports on the pcb. If you put two of them in the wrong holes it will throw up that error code...
Just a small tip:
If you do something like this again, use Wh instead of Ah. I know in the RV space people love to talk about Ah, but it is not the right unit. I saw in your video that your measuring device also showed the Wh, which is a unit of Energy. And therefore usable no matter the voltage. If someone has a 24V system, they will only use half the Ah you mentioned, but the same Wh.
Small detail from a overly obsessed engineer 😘
You make a valid point there and you dead right, RV'ers just love Ah for some reason 🤔.
@@TheWrinklyNomads because most have 12V systems and then Ah can be used basicall equal to Wh (as in, 10Ah "used up" is equal to 120Wh used)
Easy conversion bud ! Smh
@@CanadianNortherner-i8g it is a very easy conversion, does not change the fact that Wh is the more useful term 😊
@@TheWrinklyNomadsbatteri3s have 12v and consumption is always a c20 of the amp hours of the amperage max of the battery...
If i asked how big is your battery it will always be a 80ah or 105ah say...
When working out you battery needs you always say I have a 30watt light system, and then end up converting that to amps as that's what determines the battery drain and more importantly what your needs are for charging the battery to keep it in a good condition.
Thanks for this information 👍
best video so far
Thank you very much .
Ok, so my idea of connecting a 12v diesel heater with a 12v fuse block thats also connected to lights, plugged to a 12v car plug into power station will work.
Needed to know how many amps of power a diesel heater used before I decided to go with my idea, not sure if anyone else tried what I'm gonna do but I doubt it hasn't been thought of lmao
Good video thanks.
That probably wont give you good results....
They use 10amps on start up/cool down, but always worth a try 👍
@@TheWrinklyNomadstest carefully - the problem might be if the power station decides to stop operating as the glow plug has been heating things up - so you’ll need to be sure you’ve got that covered I guess?

Super helpful! I was wondering if a 2nd battery is needed for just an overnight use, looks like it would not use even 10% of a battery during all night sleep. The heater I'm installing is a smaller, 2kw unit, so I guess it would use even less power.
What battery are you using?
@@Chadlechon I went with not having a 2nd battery and my 72 Ah starter battery of unknown age had no issues with starting and running it for couple of hours at full power. Later the car has restarted with no issues (5.7 small block)
@@Chadlechon As a backup I want to assemble a step down converter that would allow me to boost the car battery from a 18V power tool battery, so that even if the car has trouble starting in the morning I'd still have a means to revive it.
thats great, thanks for sharing this
Hi, i searched for something and this, your vid came up, very good so I’ve subscribed.
Can you advise: I have a campervan with a 110ah wet cell battery. My diesel starts well, goes through the warm up process but before it gets chance to progress, after about 5-6mins the battery protection kicks in 😢
Would you say that’s correct for size of battery, is the battery needing replacement?
Also, if it is correct and therefore designed mire for EHU, can you recommend a battery so i can use off grid please? Tia!
That is a bit strange.
Wet cell gives about 50Ah available which is plenty for start up and you shouldn’t be getting problems.
Is there anything else running at the time?
You’re battery voltage may be dropping as well, but that would give an error code E01.
Alternatively true another battery that know is good.
Any lithium over 100Ah will run it 👍🏼
Perfect. Thank you
Glad it helped 👍🏼
Oh that’s a 5kw heater from the comments. Thanks for the video, always wondered. How long i can run this with a 100ah battery
they are all the same size. clones of a 2kwh german heater. it you do the math on the fuel consumption and BTUs it proves it they all output between 2-3kwh
@@fathergratwick but the 2kw is physicaclly smaller than the 5kw, i have both. Although i did turn the 5kw one down to 2kw settings, but the max on 5kw is definitely brings the temperature much faster than the 2kw one.
@@roadbiker8333 yes im aware they make smaller version too thanks for pointing out my error. I just did some quick research the larger version is a direct clone to the original german Eberspacher "D4" 4kwh heater they copied.. The smaller one is the D2 2.2kwh if you search here you will see multiple test videos where they break down the btus in the fuel consumption and all these chinese heaters ive seen tested were below 3kwh in output regardless of setting and fuel pump or advertised size. The whole 5-8kwh thing is just marketing exaggeration to sell like they do with batteries. The patent ran out on the german heater so the chinese cloned it exactly.
This may be addressed elsewhere in the comments. Just bought my first diesel heater. Honestly should’ve maybe researched more. I noticed your control is way more advanced and has many more functions than mine.
What brand/model of heater is this?
Thsnks
It’s only a generic diesel heater from EBay.
Nothing too special really.
You can get those controllers separately on eBay as well.
Very nice video! Perfect
Thank you very much 👍
Hi. Thanks for the informative video. Ive just purchase a 8kw all in one unit. Its run via a new 12v 46Ah battey with a brand new smart 12v charger/trickle charger. All is well for about 40 mins then the unit stops showing Error code E 2..... Any ideas what the problem is?....Bad battery? Would I be best changing to 240v/12v transformer, cheers. Steve
Interesting….
I believe a E2 error can be over voltage or no flame.
Judging by the power supply you have is probably flame related.
Maybe check all the fuel lines for kinks and the air intake or exhaust is not blocked.
Or ask on the Facebook diesel heater page. That’s very helpful 👍🏼
i had the same issue and found my fuel pump was actually drawing in air and i had to put better clamps on my fuel lines
Great video you are always so practical and informative ,advise if you had a smaller motorhome would you fit a 2kw?
Thanks Steve,
I think I would still keep with the 5Kw.
Would warm up the smaller volume of air quicker, which would be better.
Better to have too much than too little eh..

ATB, Steve
Great vid very informative 👍
Given these use a fair bit of amp when shutting off what would happen if say the heater was left on and the battery run out of power ??
Thus the heater not been able to pull enough amps from the battery to initiate a shut down mode .
Or does it have a cut off to save it from doing that ?
Does it shut it self off when the power gets really low ? Or does it just keep going until
Either the battery dies or someone initiates the shut down sequence ??
If it just lets the battery die without shutting down correctly then that is likely to cause issues both to the heater and persons using it
Hi,
There is a low battery error code that will show on the controller to indicate the power source is low.
If the battery gets below a certain point it will then initiate a safe shutdown.
However, if there is a complete power loss, that could cause overheat damage to the unit and melt the wiring etc.
Question about the thermostat - if you set to 21c, the heater goes to full power, reaches room temperature of 21c, then throttles down to its lowest setting. I assume when the room temperature drops, the heater will throttle back up to full power and go through the same process. Do you set the low temperature for the heater to ramp back to full power? Does the heater thermostat setting work independently from the heater level setting (1 to 5), if you set to level 3 does the heater continue to run at that level till you shut it down.
Can the heater be mounted vertically, with the hot air outlet on the top?
Hi
Yes, the thermostat setting works the same way a household one does. Set it to 21c and it'll throttle up and down to maintain that specific air temperature.
You can't set a low thermostat setting, it'll just ramp back up when it drops below the temp you have it set at.
If you set at level 3, it will stay there regardless of air temperature around it. It just ticks over at that level.
I believe there are some units that can be mounted vertically, but don't quote me as I'm not 100% sure.
Best to double heck with the manufacture's I suppose.
ATB, Steve
Great Information thanks for the effort Keep it up.
Thanks Simon 👍🏼
Mine is ran using a Ac to Dc transformer and I always wondered how many watts it was using, I can see it is no more that 40 ish watts.

ATB, Steve
its not 40w when the fans on full and the glowplug is heating.... more like 100-120 for a minute or so
I started my heater up connected to a computer power supply rated for 12V at 11 amps, it died in the first 30 seconds of run time. I'll be getting a motorcycle battery when I can get to the store.
Hi Dave

Great video, so 6.5amp hours is what it would take out of the battery, in recharge words, 6 hrs back on the charger to bring the battery to 100%? Or am I calculating that wrong? How do you convert 6.5 amps from a battery to volts from a battery?
Hi Chris
Doesn’t quite work like that, but long as you can put back the 6.5amps used you should be fine.
This will all depend on you charge amount any charge time.
You will find it varies considerably on what battery and recharge system you have.
ATB, Steve
I notice your power station has a DC output 10A max. My diesel heater, which I think is the same as yours, calls for 15A. Looks like you pulled 12amps periodically and the power station handled it. There are lots of threads on line cautioning against having too low max Amps input for these heaters, but the power station options become very limited beyond 10A. Thoughts?
HI,
In this video I'm not using a power station?
At the time of making the video I had 3x 120Ah AGM as my main power source.
cheers. Steve
I tried running a heater like this off a jackery 1000. But the high startup current draw overloads the 12v output from the thing. I might need 240v to 12v transformer capable of handling the startup current.
Yes, definitely, a powerpack will give a constant power for these type of heaters 👍
I got exactly the same problem on an Anker Solix C1000. The startup kicks in the overload protection. But there are plenty of RUclips videos where people are running diesel heaters with the 12V Car outlet of power stations....
Just discovered your channel and have found what I've viewed thus far.
When you mounted the LCD/control panel, did you solder in additional wiring length or were you able to find a premade extension or at least the same quick disconnects to make your own? --I want to relocate my LCD and capable of soldering in longer wiring but would prefer finding extension cable w/ the quick disconnects on both ends. Thanks!
Hi Evan
I didn't add any extra cable to the LCD controller to burner unit as it wasn't needed in my case.
I think it was already about 5 foot plus long.
I'm terrible with electrical measurements. Most batteries are 12v output and measured in Wh. How do this data compare to that and how big of Wh battery would I need to run this for several nights?
Hi Kade,
The controller will probably show a low voltage error with just 12v, especially on start up as it it also discharges the most at that point.
By the way, battery output is measure in Amp Hours.
The start up and shut down procedure are where you get maximum draw, anything up to 10Amps.
At this part in the video I show Amps used for a 10hr period.
ruclips.net/video/puvd9Z8zJFY/видео.html
But realistically, a minimum of a 12v 50Ah battery will do it 👍
ATB, Steve
What's the most amps (surge) at any one time? What size is you heater 2k, 5k, etc.?
I use a 10Amp fuse to protect the heater as my 5Kw heater peaks just below that.
Informative video.
Thank you.
Hi, I want to remove the old gas heater in my motorhome. It doesn't work, so I'm having a diesel heater fitted. Do you have a tutorial for when you removed yours (if you did that is). I'd like to use all of that area for storage now. Love your videos, thanks 😁

Thank you Robert..👍
Hi great vid but what size heater was it 3kw 5 kW of 8 kW?

@@johnsader8811 the heater draws a small amount of current to power the lcd display screen. It is minimal however. Best thing if off grid is to isolate all electrics to ensure there is zero draw. Ensure any switch is rated to 15amps as the unit will draw around 12ish amps on start up...
