This video will show how much battery power it takes to run a diesel heater, i test different settings and give the total run time for a given battery.
Our 2kw draws 8.5 amps on start up but ive got a 10 amp electronic battery charger connected to a 75amp 12 volt car battery when the heater slows down it draws less than 2 amps and allows the battery to recharge in maintenance mode whilst the heater operates. at 2 hertz pump dosing speed the warmth is enough to heat our 2 bed two up two down all night long, one air vent in the kitchen and one in the living room. The heater is mounted to our outside wall but the air intake comes from indoors. The burner intake is externally mounted.
So. I would just point out that the "night mode" here is intended to be a "high altitude" mode, which slightly reduces fuel delivery to account for lower oxygen. Has nothing to do with lowering output for "night" or whatever. This can cause a lean condition at lower altitudes which, for the most part, isn't a problem. Also, not all units actually do anything at all when this mode is activated despite the controller actually having the feature.
Thank you for your comment. It does slow the pump "ticking" by half therefore it does slow down the fuel as you mentioned. Because less fuel is being burned the heat output is reduced. Therefore lowering the temperature. Its better for exhaust fumes as it does not smell in this mode. And saves me fuel. So win win in my eyes lol Thank you for watching
@@justharryjohnson7250 replied to the wrong video at first. At any rate just keep an eye on thing. You might run into issues using it that way but it should be OK.
Thank you for being honest and just giving an answer to your best of knowledge ? This was very helpful 🙂 and I will use your opinion. When it comes to using or buying something 🤔 Reality always makes survival better with someone's experience and the facts 🤷 THANK YOU FOR SHARING
I guess you have to use different method to measure energy usage as this heater pump pulsing to modulate performance. So measuring instantaneous current usage with Amp meter would only work if you have huge capacitor to compensate those spikes. Or even better use battery with known capacity and measure time.
the reason these diesel heater's pull so many amp's on shut down is because the glow or heater plug kick's in at shut down to clean off the vaporising screen so that it dose not carbon up so fast,, and all the Chinese diesel heaters work in the same way,, and as an added point,, dont rely on the heater's battery feed wire's to carry enough battery power to the heater as they are very ""under rated for this job!"",, you would be far better off cutting the battery power wire's shorter and fitting on a heavy gage wire from the battery up to the heater like a ""35 amp wire"" as the Chinese only fit there heater's by using fuse wire!, and it's not beefy enough to carry the current for any distance,, this is the cause of many major start up and running problem's
I have a 2KW heater right now ( 5KW in the loft for spares) and the thing only pulls 4A when starting up and 0.6 when on idle. I get 5 days straight on 1 100ah Lifep04 battery
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.
Thank you. I like saving fuel and its much better for everyone not to smell exhaust smoke. That being said this is a very clean burning machine in comparison to others I have had
True.. and the setting is actually to make sure the fuel burns.. adequately... Not cleaner.. although that is a result as well... it isn't the reason behind the high altitude mode !
Shut Down, Stop's the self contained burn, and Uses the Glow Plug to burn off excess fuel, just like Start Up, it's the Glow Plug that pull's the power till it self burns
If the heater exhaust blows smoke.. it's not running right... if the exhaust runs nice and clean and rarely has any to a fine amount of smoke it is running right.. I run mine on 1.6 P ( 1.6 pulses per second ) .... that pulse rate burns clean and it runs a low fan rate as well as very little ( fuel oil ) diesel !
I think you meant to say it uses 0.4/0.28 amp-hours for start-up/shut-down. And draws 3.2/1.7/1 amps at full/half/lowest power setting. There is no such thing as 'amps per hour'.
Hi there thanks for watching. In the conclusion I go on to mention what you wrote around 8.10. It was quite interesting doing this as I thought they used alot more battery power than that.
I haven't yet fond the answer to this question.. But sure it's out there.. What is the best cleanest fuels one can burn in their diesel air heater .. turbine ?
Kerosene would be the cleanest burn. But deisel is fine as long as you run it on full for about half hour every once in a while. I have had mine for three years now and still running well
11:50 true but unless your van is more than a SWB you don't need a 5KW. I have a 5KW in a MWB transit and I sweat even on 8oC - yet I have a 2KW in a Mazda Bongo and I sweat at around 17oC. I do agree if you have a large van 5KW is the best - better to have one you can turn down that one you can't turn up.
So I am trying to run my heater off my Jackery 1000. I've had some people say they were able to, however my heater starts and then dies when anything more than the fan is on. But when plugged up to the vehicle works fine. So would I be correct to assume the jackery doesn't have the start up amps to run the full startup process of the heater? Should running the heater plugged into the vehicle for the start up then switching it right to the jackery work? Or is it the wires aren't moving enough power for the startup process? I can't test any of this out until tonight so I'm trying to figure out my next move. If there's a way to get this thing to run on my Jackery I need to figure it out.
This is because the power bank cannot delivery the amps needed (even though it may say it will) it may be an idea to have a small battery world in to act like a capacitor for the first few minutes of start up. It should be fine after the glow plug goes off
@@justharryjohnson7250 I ended up getting a DC to AC adapter and plugging it in to the AC side of the Jackery. Works great. I'm finally working on hooking up my actual battery so I'll rewire it to a fuse panel when that's done.
Surely someone else mentioned this.. But what the hell.. The Mountains.. signifies it's in High Altitude Mode.. as in.. density of air / OXYGEN is lower.. thus.. the burn rate will change !
Yes. The higher the altitude the less oxygen therefore less fuel is needed. But it won't damage the heater by running a leaner air fuel ratio. And it saves me a little fuel too 😀
My 5kw diesel heather taking first start up 18amp - 20amp than after 5 min turning 8amp. Anyone got the same high level amp ? And what is exactly reason ? Thank you for video.
I have a 2019 4x4 6 cylinder Sprinter van and looking at Espar heater. Could I get away with running the Espar heater off the stock Mercedes battery overnight in a cold climate?
The vehicle battery is not designed for long slow discharge it is designed to give a lot of power for a short time, you can use it but this type of use will considerably reduce its life best to get a leisure battery 👍🏻🇬🇧
My battery is 130mah. My battery is normally at 12.6v when I put my heater on it goes as low as 11.3v is this normal? Problem is..when it’s at 11.3v my light flicker ever so slightly? Is my battery damaged?
So a question I have is I've been parked up in my van for 3 hours with the engine off and the diesel heater on in the back and its running off my main van battery , I'm just trying to find out how many hours I can safely run it for with our risking my van not starting
thats a hard question without knowing your battery size but to be on the safe side i would run the van until the glow plug is hot and not drawing the startup power and same when the heater is shutting down.
This depends on the size of your main battery, its age and health. Best to get a battery in the back then you know the engine battery will still start your engine
It used 8 amps on start up and 1.6 amps (or something very close to that) to allow the heater to run. Basic math shows it using 6.4 amps more on start up and the only thing different on start up is the glow plug comes on. Therefore the glow plug uses around 6.4 amps
Yours may be an older version heater. My first one never had it either. This newer one does. I would not worry to much as long as it heats when you turn it on its doing its job
Hi, not it's not OK. Your van may not start. You should consider a separate leisure battery to run the heater. It uses 10 amps for 15 mins to heat up and cool down, before you get heat you've used half hour, or 5Ah. Run it overnight for 12 hours, that's another 12Ah. So your battery is now 60 - 17 = 43 amps.
Yep. I was just about to point out the difference of using SLA, AGM and Lithium. The first two are correct in how much they can be discharged, while Lithium does allow for 80% discharge and more than double the charge/discharge cycle of an AGM and a SLA. Some LifePo batteries do allow 100% discharge although I've never tested that.
Ditto on the appreciation for taking the time to do this test and share it.
Excellent, love the way you showed consumption using a 100 amp battery. So understandable. Thank you

What you called night mode is actually the high altitude mode and it lowers the pulse rate of the pump to change the fuel to air ratio to burn cleaner
Thank you.

its not good to shut it down at that speed as it can coke up the burning chamber best to turn it up to full 10 mins before shutting it down.
Thats true. The newer ones have a shut down cycle that stops this issue
I think you meant to say it uses 0.4/0.28 amp-hours for start-up/shut-down. And draws 3.2/1.7/1 amps at full/half/lowest power setting. There is no such thing as 'amps per hour'.
thanks just the question I needed answering1 appreciate your efforts.
Thank you for watching
I'm sure that the rise amps on shutdown is due to the glowplug coming back on to burn off any diesel left in the chamber.

Good video can I charge my car battery while running the heater
I use solar panels to charge the battery while I'm using the heater. It is safe to do so as long as you don't charge higher that 14.7v
thanks for the video
Thanks for watching

This is true. Even on minimum my mwb van creaps up in temperature. But it is nice to be able to quickly heat it up with the 5kw.
Um ... charge (consumed) is current x time and not current / time. Therefore, it's NOT amps-per-hour but "amp-hour" or Ampère-hour.

How long is a piece of string. You dont provide any information so an answer is not possible.
I have 3 750 cca batteries and at start up it kills the battery even if I put a car battery charger on. Is there any way to start it up easier?
You need bigger wires .. the heaters wires are too small to begin with
Cca mean nothing. Its the amps that battery has that matters. Your heater will never consume the cca the battery can provide.
Can you explain how a 88-98W glow plug consumes less than 0.4A at start-up?
It doesn't
It used 8 amps on start up and 1.6 amps (or something very close to that) to allow the heater to run. Basic math shows it using 6.4 amps more on start up and the only thing different on start up is the glow plug comes on. Therefore the glow plug uses around 6.4 amps
Drawing 6.4 amps but for a short length of time, so it is high amps per hour but for a very short length of time...
@@justharryjohnson7250 can I use my ecoflow river 2 that is 8 amp dc out put.
