Chinese Diesel Heater - Battery Consumption in Ah

[@mikeries8549]

It's amazing how when you publish any type of technical information ....guys with lab coats and degrees pop out of the woodwork. Simply amazing. 😀

[@mariofelix3399]

It's a bit boring and geek style video, but for those who know, like me, it's extremely useful. Thank you for your patience doing this.

[@wheater5]

A useful video, clearly explained! I recently fitted a 5 Kw heater in my garage and initially ran it from an old, small capacity car battery, which isn’t in the best of health. I kept the battery topped up with a permanently connected car type “smart” charger. I then decided to buy a 30 Amp mains power supply and run it directly from that. I found one with a display which shows volts and amps. The output can be adjusted from 9 to 15V or switched to a steady 13.8V. I tend to use it at the 12.8V which is the maximum recommended in the heater manual and unlike running from a battery, irrespective of load this voltage is maintained. The current draw varies in exactly the same way as yours does. As you found, the highest load is as expected on start up but similarly high on shutdown. As I understand it, the heater must be allowed to run its pre-programmed shut down sequence so the fan blows at maximum to cool the heat exchanger right down. If this doesn’t happen, heat runs “backwards” towards the inlet end and can overheat the circuit board components.

[@DanSohan]

I hadn't considered how the heat could cause thermal runaway and damage electronics that way. Hopefully an unlikely scenario, but certainly best to always allow proper shutdown. I often run the heater with the engine running and the alternator voltage sitting at 14.4V and it hasn't cause anything to go bang yet (on my particular model). Would expect a little headroom on max voltage. Recently build a diy LIFEpo4 battery at 80Ah to run it and that sits at about 13.4V.

[@wheater5]

@@DanSohan I’m just going along with the recommendations in the manual that came with my heater with regard to the correct shutdown procedure. I agree that the voltage tolerance should allow for the fact that most vehicle alternators are designed to charge the battery at about 14.5V.

[@joedunne6737]

I did the same for my workshop but you have to be careful because in the event of a power cut the heater won't go through the shutdown cycle which could damage the CPU. I would keep the battery connected for that reason.

[@wheater5]

@@joedunne6737 Actually, I’ve owned this house since 1988 and I can’t remember the last time there was a power cut here, fortunately they are very rare in this part of the world. Unfortunately, the instructions for the power supply I have specifically state that it’s unsuitable for connection to a battery because it provides a constant voltage (it would boil away the electrolyte). In any case, in the unlikely event of a power cut happening, a new ECU for these heaters only costs about £16 and probably take me about ten minutes to change. So, not really the end of the world.

[@stevew9957]

Really appreciate the effort to produce this video. It's given clear details on the 5Kw diesel heater power consumption during test with the data being used to give best and worst case of battery use over 24hrs. It clearly indicates why some owners complain their battery bank is not lasting, especially if it's a few years old and it's cold.

[@jcardosa02]

what battery do you think is best for the 5k diesel heater? i currently have a 12v 200Ah battery but it’s bad and i have to replace it. it’s pretty expensive but if that’s what i will need for the heater then i guess i will get it 😭

[@Fromatic]

Very useful, this makes me think when I install one I'll leave it on lowest Hz setting rather than temperature, to make sure on really cold days it doesn't ramp up trying to reach even a low target, but just stays on its lowest fuel/energy usage which should always be enough to keep a small van comfortable enough I imagine

[@DanSohan]

Yea, it doesn't take much to feel comfortable. Luke warm water feels great when it's frosty outside!

[@ralph1881]

If you're not running it full heat before shutting down you'll likely have excess carbon build up and premature problems. Run it full blast for 10 minutes before shutting down and clean it out

[@snipermx06]

From video I seen, the pump should be upright or 45 degree angle to keep air bubble stuck in the pump. Helps the pump. Thanks for the video, this is a huge help

[@fannyschmeler223]

For air to escape from pump !!

[@staritpro1775]

Best angle for pump is about 35 degrees with the output end up (usually where the power connector is) as it needs to lubricate the pump and get rid of air bubbles.

[@GrumpyGarry121]

Thank you for this video, the internet is full of useless or incomplete info, means I can now make a reasonable informed choice of battery amperage. Very clear information!

[@IW4DBX]

Under password settings, you can set PF6 to 4 to slightly reduce the glow plug power during start and stop process. PF1 to 3 is for 40w glow plug that I've never seen as spare parts

[@DanSohan]

Will reducing the power not increase likelihood of carbon build up. Although sounds very useful if your running on a smaller capacity battery or running low.

[@David-kd7vl]

Never seen pf6 or pf1 on the controller have you a photo of this ?.

[@omulmodern7663]

Thank you!

[@DavidLaFerney]

Good work! I installed a battery monitor in our RV because I had the same questions and concerns about how long we could dry camp on the existing batteries during an upcoming 16 day trip into the Rocky Mts (USA.) a bit of testing and math made me reasonably confident that what we had would work. And it did. Just to be clear - our (2 lead acid) batteries are good for up to three nights in a row. We were able to charge the batteries at least that often with either shore power or the Victron DC/DC charger I’ve installed on our tow vehicle. That’s another story though (spoiler - works Great.) The point is this - you need a good battery monitor - otherwise it’s like a car without a fuel gauge - else you never know how much you’re using or how much you have left. I used a Victron Smart shunt, but there are others that will work depending on the application. The Victron is great though.

[@jcardosa02]

hi may i ask what kind of battery do you have? i am trying to buy a battery to connect to my solar panels(2 100 watt) and get a diesel heater but not sure which battery i will need to buy 😭

[@DanSohan]

The one I was using was a Halfords branded leisure battery. They are not the best I've had. The upgraded one is a LiPO4 type, but I had it imported from China and made it myself. I don't think you'll find them in stores for reasonable prices yet.

[@Merc-Rover]

Thanks for taking the time to make this video. I have a 300Ah battery bank so I should be good for a few days :-D

Ok so you got a big battery good for you.... ;-p yeah i would imagine that you don't even run it all when you are sleeping. I have a T5 well insulated. With two in bed it around 0°c nice and warm. Only cold when you get from under the sheets.

[@gordonmitchell729]

Excellent information. That answers my question about the battery usage. I'm wondering about buying a power unit and possibly an inverter! Thank you for a great video.

[@joedunne6737]

Interesting, thanks for that. It's also crucial to let the heater go through the shutdown mode for another reason. The CPU unit is close to the heater fins and will cook the components if you don't let the heater go through its shutdown cycle.

[@bigoldgrizzly]

Absolutely right ! Many folks run the supply from a battery that is constantly connected to a mains fed 'intelligent' trickle charger to contend with power cuts.... no stranger to many who live 'out in the sticks' The fully charged battery will give a certain amount of continuity for the heating if the power goes off and I have been told that, as the battery gets emptied, the CPU will sense that the battery voltage is dropping and will initiate a proper shutdown procedure while there is still power available to do so. Can anyone confirm if this is the case please ??

[@jamesc6526]

Amazing breakdown on battery consumption. I can't wait to see the real world test. I would love to see what kind of fuel usage you get as well (I kinda know what my 5kw uses, but it's straight estimations).

[@DanSohan]

It drinks about 5 litres in about 30 to 40 hours of constant run at the lowest settings.

[@petecoventry6858]

this IS the real world test!

[@igorbogdanoff4517]

Superb. Thanks for this. I've equated that my self contained unit in a peli case, with a 12ah lifepo4 running a 2kw heater will give me three 1hr heating sessions (one session at night before bed, for three nights - three initial starts, 45mins normal usage, and then three shutdown cycles. Should bring the van up to temp before we hunker down for the night - being well insulated the van should maintain a good heat over night with body heat of two people replenishing any that gets lost over night. If we want heat in the morning aswell we'll only get two nights and two mornings, and well have to reduce heating session to 35mins per session. I'm good with that!

[@DanSohan]

If you add a 100W panel to the system you might be able to keep that topped up

[@laurenceperkins7468]

Big thing with lead-acid is called the Pieukert Effect. Basically the more amps you draw, the less efficient the discharge gets. Run it hard and you might get as little as 30% of the available power. A tiny load on the other hand may get nearly all of it.

[@elbuggo]

The label is calculated on a fixed load over 20h.

[@petecoventry6858]

Yeah - I got a Ford Freda and it had a KA battery - it got down to -3 and at 12.4V the heater ran out at 3am. I replaced with Lifep04 and a DC_DC charger and now it runs all weekend at 17oc like it did before and I can get a full weekend out of the battery without charging it.

[@gatecrasher1970]

can you explain how the voltage of your battery went back up?

[@scottlawson1800]

Fantastic video, thanks for doing this! I would estimate a mid point between 17°C and 35°C (26°C) would probably end up using roughly ~3 Ah using these numbers. Maybe even a bit less if the heater could reach maintenance mode, and good insulation

[@DanSohan]

I've been working from the van over the last week. Finding running it in Hz mode is better, just ticking by at 1.6hz uses a constant current and battery is lasting better. May do a follow up if I have time...

[@kst357]

In both scenarios the square footage of the cabin space to be heated will be a factor. With everything being equal such as insulation, the number of windows, and so on, a smaller van will heat up faster than a large one so the heater would theoretically run for shorter periods. I'd like to see an experiment to see what the battery usage would be for different sized heaters to heat up the same amount of space. My guess would be that going up a size would save battery usage but result in more fuel consumption.

[@Michael.OJackson]

If you are going to the mountains are you aware of the alpine setting which slows the pump for higher altitudes

[@itsruffoutchea6636]

Man this is a good video. I love real world test better than oh it uses this much power figure it out yourself. I was surprised it used so little battery power. Looking to switch from propane heating and electric blanket. This uses less power than electric blanket at 3 ah.

[@blumaxx1]

U can extract more heat if u put a heat exchanger on the exhaust,,because the exhaust runs about 300-450 degrees Fahrenheit , It will double the efficiency of the heater

[@travishanson166]

When I install mine, I will be boxing in the exhaust and putting a heater core in there to heat my coolant in my van to use for block heat. Will use a vw coolant recirculation pump with an arduino pwm speed controller.

[@captaindave47]

Creates a lot of certainty/confidence that you are not doing something ridiculous.

Hi. i was thinking of doing the same thing. occasionally i will run my fridge but since it’s cold i don’t think it will need to be on much. do u think this will work? i will have 200 watts of solar panel. will 100ah battery be ok?

[@leeh.4729]

Mine has been working fine. I don't have it on all the time but now that the temperature is dropping in low 30s I turn it on for about 3 hrs. and it never drops below 12.4

[@davidconner-shover51]

if using it in the temp setpoint setting, the power usage will be highly dependent on ambient outside temp. startup burns a bit, about an AH, a bit on shutdown as well. max fan seems to draw about 4 amps, min settings seem to pull only 400-500ma

[@Kryptkeeper911]

Rule of thumb with lead acid only drain 50%. Or you’ll kill the life span of the batteries. They aren’t meant to be drained to nothing. It will damage the walls in the battery and won’t hold full capacity. But a 12v 120ah battery will run that for 2 days at the least

The heater unit works on 12V, so therefore relates to a 12v scenario. The meter also measures Wh, but this video was describing usage of Ah from a 12V source, for those that wanted to know. Really, if the battery is 100Ah, and 12v, that's 1200Wh, when the battery is at 50Ah remaining, the heater has consumed ~600Wh, not difficult to work out / estimate?

[@vevenaneathna]

@@DanSohan I assumed most people would be using a lifepo4 battery which usually operates on 13.6v when full, and almost 15v when charging. doesnt got to 12v until its under 10% capacity depending on load and health. i usually charge lifepo4 batteries at around 14.8v which is nominally around 25% more wattage for the same amount of amp hours. 12v world is very confusing.

[@toneault7499]

and you use 3.2 litres in 24 hours on a none stop run. we use two to heat the bungalow. one each end running on heating oil at 39p per litre . if it helps

I would love to use these to go off grid. Thanks for the info. A project for the future maybe

[@toneault7499]

@@DanSohan fyi.. you can use heating oil. as well and that's even cheaper

[@DanSohan]

@@toneault7499 indeed, I like to mix a little engine oil in with it to help recycle it. I realise this will probably kill the glow plug, but give me a reason to open it up and tinker if it does :)

[@mickpatton617]

Great test , u never mentioned volts though . Them heators cut off at 10.5v Without inishiateing the cooling shutdown process. This situation cookes the motherboard and the unit is scrap. A visual voltage display will avoid this situation. Simply start the van up then shut the.heator down untill u have sufficient power. ( when parked up ) cheers.

[@DanSohan]

Mine actually runs through the full shut down process when the battery voltage gets too low. Least it has done twice now.

[@terrellstewart4071]

In the real world usage of my heater some time b4 morning it shutdown and got real cold the battery was to low. Two batteries will work and a solar panel to charge one while you use the other but I'm interested in your real world use results plus I had a brand new 100ah lead acid battery now I'm concidering a 12v power converter to assist the power use

[@DanSohan]

We upgraded to a LiPo4 battery, they give far more amp hours compared to lead

[@fannyschmeler223]

You don't want to have that pump running on a horizontal plane mate, the fuel naturally releases a tiny amount of air as it goes from high pressure to low and that air needs to escape from pump or you will damage it through lack of lubrication. It should be ideally vertical with outlet on top and definitely no less than 45 degrees .

[@DanSohan]

It is at an angle, all good 👍

[@sterogerson4177]

Start your van get the heaters on then use small heater for maintenance

[@Wozza1534]

Can I run my 5kw heater with a 13.8 volt supply from a bench top power supply?

[@DanSohan]

No problem if it can provide enough amps for the glow plug and startup. I heard some like to use a small 12v and bench supply together. I think if the bench supply can do 10amps that should work.

[@Wozza1534]

@@DanSohan thanks buddy, yes it is a 15 amp supply so should be cool, much appreciated

[@jcardosa02]

can u pls tell me what battery u use for this heater? is it a 200 ah battery? and is this a 5k watt heater? idk much about this stuff just trying to hurry and get what i need before it’s like 9 degrees out (that’s the coldest it gets here )

[@DanSohan]

At the time I was only running a 100Ah lead acid leisure battery, but it wasn't enough. I have since changed van, and now run a 280Ah battery, with 150W solar. This keeps it running for about 3 days for needing a top up from the engine. Problem with a much larger battery is it takes so much longer to charge back up. The solar is great in the summer, but it's started to struggle now the days draw in. I actually find a really good sleeping bag and a well insulated hot water bottle work really well.

[@jcardosa02]

@@DanSohan aww that’s nice. u currently have a 200ah battery but i think it’s bad now. it dies very fast with just my max fan so i think i have to buy a new one. i have 200watts of solar.

@@DanSohan when u had the 100ah. how cold was he weather that you were working with ?

[@DanSohan]

@@jcardosa02 It generally not much below 5 to 10C in the winter here. But 1 night it got down to -10C and the battery gave up at 4 am in morning. Luckily the backup blankets did the job. Turned the engine on when it got to about 6:30am. The heaters do use more power to fight the freezing cold. If you have access to them, a power meter would help decide how much power your getting through. Something that does Amp hours or Watt hours. Then you could figure out if your battery is failing, or you just need more storage.

[@jon_14_6]

Hi, great content thanks. If the voltage had been 12.8VDC it would also have had a positive impact on the AH result

[@DanSohan]

If the voltage had have been higher, it would have pulled less amps at that higher voltage. So should have been very close in results, although yes, efficiency would have been slightly better

[@D.A.T.GRINGO]

awesome video, thank you!!!

Thanks! I appreciate the + feedback!

[@rhodrilazarus8385]

Can this be wired up to a van's starter battery?

[@johnstarkie9948]

Yes, but it would be a bad idea. If you flatten your starter battery you won’t be able to start your van! In principle, use your starter battery for starting only.

[@bobbyholman9944]

So where the best place to wire the heater too

[@DanSohan]

I wired the live directly to the leisure battery with inline 20A fuse with the supplied cable and the ground using a ring connector terminal to the stud that the chair was bolted to.

[@bobbyholman9944]

I connected it to the leisure battery and it kept killing the battery off how can I stop it doing that

[@DanSohan]

@@bobbyholman9944killed if off? As in voltage dropped too low? Need a better battery is my guess without see the setup

[@bobbyholman9944]

I’ve wired the positive and negative straight to the leisure battery and the leisure battery is connect to the relay that’s connects to the starter battery and it kills both battery and the vehicle won’t start

[@DanSohan]

@@bobbyholman9944 sounds like something is up. It should run for at least 15 to 20 hours if the battery is good. And if the split charge relay is not protecting the starter battery something is very wrong

[@marysstilllearning5803]

I have a question that has me stuck on my install?, if anyone could help it's so appreciated do I connect my diesel heater to the battery straight or do I hook it to my solar charge controller I noticed it has a fuse on it already I'm so confused and the instructions are useless

[@DanSohan]

It's recommended to connect straight to the battery. The heater will automatically shut down if the battery gets too low. If we're not using the van I pull the fuse from its holder to prevent the display draining the battery.

[@marysstilllearning5803]

@@DanSohan thank you soo soo much its got cold im in a rv. Lol. If I cud ask one more question can I leave the solar connected to the battery at the same time that the heater is attached to,? I hope I ask that in a way that makes sense. Lol thank you so much for the info u gave me, already

If you have a better battery and you maintain a higher voltage your current draw will probably be less.

[@DanSohan]

That it will, but nearly all batteries will sag in voltage level with a 10amp load on it.. only time you'll see a level over 12.2v is if the engine is running or you have a few batteries in series.

Great video! Correct me if I’m wrong. In hertz mode and set at the lowest output, it SHOULD draw in the 20ah range regardless of other variables like temp and insulation? You just may freeze your knickers off...

That's what I believe to be the case, but I've not tested it in the field.
