I had a few vids to choose from..mostly they were from young dudes then I saw an older gentleman with silver hair and a nice pullover and I said to myself, "Tony, this man looks like he knows what's up"

Thank you for doing this test. I am putting in a diesel heater for this winter into my Van. I've watched many videos and no one seems to talk about the power usage. I want to make sure my battery bank can handle it, so thank you.

having a real world test is really very useful, thanks! love the series!!

Great informative delivery. Thanks AJ

Thanks for the informative video. This answered my exact question.

Thank you so much for the information. You answered all of my concerns regarding power usage.

Thank you for a very informative video

Thanks ,doing my initial lay out and your vid was very informative'

Brilliant video. About to install one of these in my van and couldn’t decide whether I’d need another means of producing power. Now I know not to bother!

Great test and very informative, thank you from Australia 🇦🇺

Very comprehensive look at the electrical needs of the diesel heater. Appreciate the video as I'm shopping online for an AC/DC adapter. I'll be looking for 10 amps capable to be on the safe side. 👍

And yet again, you made another excellent video. Well done Sir.

Pretty straight forward, and chock full of good, clearly presented info 👍🏻👍🏻

This guy is awesome. His installs, trials, and explanations are really helpful.

Love that little meter been using it for years for testing items. Its so simple to get data from.

Excellent video, thank you!

Really good thanks just about to set up a heater for my shed/Greenhouse hoping it will work

Can I just say your presentations and information is excellent. Easy for a numpty like me to understand and hopefully one day install and run a diesel heater. Many Thanks indeed...........

Solid factual information which was well presented - what's not to like. 10/10 and thank you.

Thank you for the vid . My 2x110 ah barber's with solar charging should be great thanks

Thanks for that info on diesel heaters. That answered the main question of what takes the least amount of power to heat an rv.

That's some great information really helpful Thanks

Thanks for this information 👍

Thank You, very useful and easy to read information.

Thank you for this video, its really helping

Great Information thanks for the effort Keep it up.

Thanks for this gr8 video it so simplethe way you explained it mate

Thanks for that very informative film. Hope you didn't overheat too much. Happy New year

Very great analyze n process! 💥👌 Very interesting thank you as I have recently received a china diesel heater 2 kw and will install it in my campervan and I have 280Ah lithium batteries!

Thank you sir !

Thanks a lot for a very clear explanation!

Thank you very much .

Very helpful video, thank you 👍

Great information. Thanks Don

Thanks for a very comprehensive and straight forward report on the facts people wanted to know. I bought one of these to use in my project car since it's powered by an air cooled motorbike engine that would be hard to harvest heat for the drivers compartment. Had a few doubts whether the 35amp alternator would be able to cope with the heater, but now all worries has been put to rest. Looks like I'll even be able to use it for pre-heating the engine compartment in the winter for easier starts. 😊👍

Good clear video. Thanks 👍

Another great video, thx for sharing

That is what I wanted to see, thanks for video

This is a great explanation it's clears up for me that the start up of say 7 amps doesn't actually take 7 amps off your battery.

Very nice video! Perfect

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. 😃

Great video, gotme subed!!

Perfect. Thank you

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

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.

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).

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

Informative video.

Good vid so useful 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.

Great info! You get a sub.

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

Great video you are always so practical and informative ,advise if you had a smaller motorhome would you fit a 2kw?

Useful thanks.

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

Best Video

Good stuff.

Well made video, Dan. Which make and type of diesel heater are you referring to ? Thx for sharing this technical analysis 👌

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

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.

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

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!

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 .

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?

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'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)

Brilliant

Hi - thanks for an informative video and so well explained. I am currently having an issue with my chinese diesel heater which is installed in a work van, Citroen Relay. Heater is powered by 115 Ah halfords leisure battery ( battery code hlb681) that is over 3.5 years old. I have run recently run the heater for almost 24 hrs without starting the van without when it stopped working. I have since driven / idling the van for about 10-15 minutes to give some boost to the battery. I managed to start up the heater and it was running for 2-3 hours when it stopped again. I then took voltage reading at the battery and it read 11.49 volts. I am assuming the battery has dropped below the required voltage level to keep powering the heater sufficiently. Can anyone advise please?

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.

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.

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 👍🏻

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.

Very useful info, i will use this on my sailboat. Uses a lot less power than i anticipated, you earned a subscriber :) !

CAn I ask a question my friend please. I want to set one of these units up with a 12v 7amp battery which will be permanently connected to a 12v 6amp smart charger. I know the glow plug cycle draws around 10 amp, but only for a very short period which the 7amp battery should be able to cope with. The 7amp battery is not ideal, but do you think with the combination of the permanent smart charger I will be ok? Many thanks in advance.

Love the vid! 🙏 What size is your diesel heater? 2kw 5kw 8kw?

thanks for a video. am I missing something here please correct me if I am wrong. So board computer, fan and glow plug on a start-up is using lets say 7 amps for 5 minutes. then it keeps heating space at lets say 2 to 3 amps for an hour. then it goes through a finish cycle to burn glow plug clean i assume etc for another 5 minutes. so why is it then that you say its avarage amps per hour is 0.5?

Hello… Great video… I am planning on fitting one of these heater’s in my workshop using a transformer from 240 to 12v instead of. Battery do I need to place a inline fuse from the transformer to the unit. What size fuse would I use thanks Steve

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 ?

Great video! Would you say it would be fine to run off a normal starter battery (90-100ah) for say a day van scenario, short weekend trips ran for 4-6hrs max in one night but to start car in morning to charge it back up?

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?

Just subscribed , great video very informative, one question though, can you use red diesel in these heaters?

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?

Thanks for your video, but I'm easily confused. I've ordered an 8khw diesel heater for my garage and wondering what I should use to power it. Car battery/Leasure Battery or mains power adaptor? Thanks

Im curretly looking at one of these heaters for a shed and greenhouse. The shed has a small 30w solar panel if the total power used is 13.5 ah in 24hrs would a 30w panal be good enough to replenish the charge.

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 😁

Hi it looks like you have changed your system a lot since I last saw it, I had watched you change twice but this looks much neater. Can I ask? It look like now you have the back of your heater for air to be outside your van is that right? Because it appears to be against the wall. I have not done any technical tests like you have but this is what I get. I have the same size van as yours I think ( Auto Trail Scout ) a new fully charged batter with nothing to keep it charging while running lasts me 7 days before there is a E 01 warning light meaning not enough power in the battery, for other who don’t know what that means, I know you do. I work away 5 nights a week, my heater is only for my on suite bed room. I have it on power 2 for 30 mins every morning from Weds to Sunday. And 3 hours a night from Weds to Saturday as I go home Sunday night after work. To see how long my battery would last doing those time without charge I found my battery would last 7 days and I would need to charge it. But that is no good for the battery because it is totally flat. I recharge my battery every Sunday when I get home at 8pm till the next day and it works great for another week. Just giving you an idea of what I found with mine. Great video as always I wish I was as handy as you your set up looks so neat compared to mine. Every time I get a week off I am away somewhere so never get the chance to do anything. Thanks for sharing Ray k uk YNWA.

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

Hi what sort of solar panel do I need for keeping the leisure battery topped up...only using battery for the heater whilst camping...thanks for any advice

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! I hope you'll oblige me a quick question - what number of amps does the 12 volt battery need to be to run this heater? Thanks, Sam :)

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

Thank you

I've wondering can I use a standard 220V(AC)/12V(DC,

What's the most amps (surge) at any one time? What size is you heater 2k, 5k, etc.?

Would this run off a 42150mAh power pack at all? It has a 12v lighter socket on the lithium pack. The pack im usings specs are. Capacity: 42150mAh @ 3.7V / 13Ah @ 11.1V and 12v DC socket: 156W max I would want to run this 8k heater for 3 days into a tent the one I have is a portable unit all built into a case but there all the same I assume

My manual for the same heater recommends a voltage range of 11.5 to 12.8. However, when charging the batteries (solar), they can often get up to 14.5V. Can you see anything in the manual or the manufacturer that has a maximum voltage?

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.

what was the maximum amp draw at any point in time?

Can i wire a 5kw heater straight to my t5 transporter t5 battery? Would this kill my battery overnight?

May I please ask I have two 110a agm batteries in parallel so all up 110ah usable power , may I ask would this be ok to run the unit for a few hours each day in a camper
