Chinese Diesel Heater Power Consumption. How Many Amps Do They Use And Is Your Battery Big Enough?

Is you battery big enough to power a diesel heater? How many Amps do they use? How much Amp Hours will it use from your leisure batteries?

Worried about running your leisure battery down while use a diesel heater in your motorhome or camper van..?
So was I.!
In this video I run a full test on the Chinese Diesel Air Heater that's fitted to my off grid motorhome.
I test out startup Amps, raising the temperature Amps. running Amps and shutdown Amps to see how many Amp Hours is required and if my batteries are man enough to cope with the load.

Although very specific to my motorhome, I hope this give some indication of the amount of Amps being used and the total Amp Hours of these Chinese Diesel Heaters.

Meter used in this test was the: DC Power Analyser 60V/100A Watt Meter.

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.

Thank you!
Bought one of those as a standalone unit for tent camping in winter. Bought now a 20Ah 12V LiIon Pack and am confident that it will run the heater for a few hours, especially on minimum heating levels, which is all I need for the tent.

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

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"

[jesperholmelundulff-kalles]

Thanks for your info.
I did change my wiriring so that i can switch between car and house battery as far as power for the heater goes.
That to make sure i always have power for cool down of the heater...

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. 👍

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

[daydog]

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

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

[Yukonjackman]

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

[RASMUS]

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. 😊👍

Steve, brilliant! Perfect timing. I'm considering getting a couple of those meters and monitoring things like our fridge and freezer for a while, especially coming into our summer. The heater will be unplugged once the current antarctic blast stops, but I've always wondered about its power usage. Thanks, from a couple of Australian wrinkly nomads. 🇦🇺

So quite easily a few days off grid? Add the solar panel and looking good. Thanks for the upload. Very helpful

[anderscederqvist]

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!

[donner]

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.

[CanadienNortherner]

On a 5kw CDH I've gotten about the same readings .
Thanks for the video man !

[grahammutton]

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

[mikeb]

Great video sir. Providing the value no one else was 🙂

[garrynorth]

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

[stanthevan]

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.
