Testing a $140 Chinese 8KW Diesel Heater  

Thank you for the great video! I was contemplating buying one for emergency use . Looks like not a bad idea to have one.

Nice! This would be just the ticket to heat my goat barn. I will build an outside enclosure for it and duct the heat into the barn. The "barn" is a 12x16 wooden shed with OSB steel covered roof. Should keep the little girls ( dwarf Nigerian) toasty warm! Beats trying to use electric heaters! (Yes, my babies are spoiled 🤣)

I ordered one to put in my van so I can sleep in the van when I'm on the road doing gigs. I will likely replace the propane furnace in my 1970s slide in. Furnace still works but draws too much power. I will use that on multi day gigs so I have plumbing, fridge and stove. The production trailer will get one to keep equipment warm on below zero days. And I will likely buy my dad a few for his trucks and his "house" .

they have been using these in simi trucks for many years as bunk heaters a lot of co. still use these now

We have a few of these, use them for preheating aircraft engines, just stick the hose end into the cowl and let it run. They slso work great for preheating tractor engines as well in unheated sheds.

I just had one of these installed in my Lobster boat. It doesnt draw a whole lot of power and it puts out a good amount of heat. Running wide open it only burns about 2 to 3 litres of fuel in a 16 hour day!

I have a similar one in my shed 10x10 FT. not insulated it will keep it warm enough to work in most cold winter days. Run exhaust out through smaller hole to not loose so much hear, door braced open is a lot of cold air.

Just put one in my snowmobile trailer! Can’t wait to see how it does.

I don’t know what kind of diesel heater he has but I have an 8 kW diesel heater hooked up to a 6 gallon and when I run my diesel heater on full blast nonstop it takes seven days to go through 6 gallons of gas in my 30‘ x 15‘ camper trailer and when we have -30° weather in the winter time in the northern part of Wisconsin run on full blast in our houses basement so our pipes don’t freeze and it keeps it good 65° in our basement but when we heat our basement up 6 gallons of diesel fuel will only last 3 days on high

I installed a Chinese Diesel heater in my 6x12 cargo trailer conversion... I spent all my effort making sure I properly exhausted the unit through my 1 inch insulated wall using a thru-hull stainless outlet as well as using high-temp RTV around my exhaust hose with high quality hose clamps, and thought everything was great.. I now know that I need to also properly setup a thru-hull port for the combustion intake (away from the exhaust). These devices are primitive.. don't trust that the exhaust flow will happen in one direction with 100% certainty... and don't expect your Home Depot CO detector to save you either.. I've smelled the funky smell, and let it go... and it made me pretty sick.. Don't ignore it... do it right. ...also, if you drop the diesel pump frequency, the exhaust-to-intake leak is even worse... Treat the combustion intake just as important as the exhaust itself.

Thanks for the review! I have been thinking about one of these. I hear that power stability is an issue. You would not want to run it off a 120v converter because if the power were to go out while it is running it could be very bad for the unit. It needs power during its shutdown sequence, and it must be shutdown properly. I would like to see how long you could run it off that battery or maybe off the 12v output of a solar generator.

This would be a good boat heater. In boats, diesel is preferred as compared to gas or propane due to fire. It is also lots cheaper than alcohol and kerosene.

got the Vevor heater without a case mounted outside my cabin. Got some issues with starting it after having it sit there for three months. I guess this is normal? seems like the diesel is clogging or something.

I have 2 in my garage, looks just like this but eBay they are only $86 with 2 day free shipping

The one ppl hook directly up to the fuel tank is either a Wabosto or similar one. They have those even for regular gas check out VanCity Vanlife

Yeah I live in Canada can't afford electric heater 220v , OK I'm sold thanks

Nice review, i have got a question for you, did it smell like burning plastic or rubber? Thanks

Hi there, thanks for some good clarification. Would like to know how it's going after some use. I'm really puzzled how they show this sitting in a car. Who in the world would cut holes in a car for the exhaust? Dumb. Does it smell of diesel inside? Thanks

No ticking on This one? Interesting..

I love mine!! but I don't believe it's 27k but Max 15k btu

You need to meet Meredith at 6:00

Is there something like a battery charger I can put on the battery while the heater is running to help the battery due to the large draw of power ? Thank you for your time.

Kas atsitiktų jei veikimo metu dingtų elektra?

Looks pretty flimsy. Might be ok in a static position but dont think it will last long on the move.

Hello Dad. If I try to use this in a shed with a 220 volt extension lead, Please tell me what I will need to make 12 volts of power? Thank you.

Is it possible to plug into a regular outlet in a shed to power it?

id be interested on burn time for a gallon of fuel and this could run on used moter oil . great vid , thanks

How do I connect the wiring to my Jackery?

Super resistente a bajas temperaturas

How did you pair the remote to your controller

I would have thought you would need a power inverter to use this heater but I guess it was wrong.

Why are they always out of stock?!?

👍

Can you use these in van living?

Sadly this heater are sold as "8 kw" heater. it`s only 5 kw. Study the fuel consuption.

Use kerosene and the combustion chamber will not carbon up at all.

97 bucks on amazon right now

I so hope this channel doesn't migrate to a Wranglerstar clone where it's just "product reviews" (aka 'commercials') all the time.

Check out the german made Eberspacher portable diesel heater. Same thing, only quality.

Take the energy density of diesel and then look at the pump rate, and you will find that 8kw would be denying the laws of physics. Any of these labeled over 5kw is a lie, exaggeration at best.

The 8k is a chinese marketing con. Like those 1000000 mAh rechargeable batteries... I wonder why they do that and mostly why amazon let that scam appended. Because the sad thing is that sometimes the batteries or other product are on par with the best real ones but way cheaper but other times are real scam... That unit is a 5k i believe. At 1/10th of the price of the original it's a good deal for what you pay for. Just don't depend on it . ( like surviving at -40 with no backup ). But i don't understand why they have to lie about the power and exaggerate. Maybe it's a chinese thing because they have little... Self esteem !o! Anyway the exhaust is really hot and wonder if he burn his door screen. Especially that they are mostly made from plastic lately

Don't use this in a camper! You may not wake up in the morning

Looks like an excellent appliance to burn your house down.

THERE cheaper on ebay

How long does the battery power last before you have to shut the heater off and recharge the battery

I have one in my garage- 20x24 garage and living up here in northern Canada where it gets to -40 it's handy. I can keep the garage above freezing with one. I ended up building an exhaust out of 1" copper that goes up and over the wall and out the eaves. I ended up putting a T right at the end of the flex exhaust hose and short piece of pipe to capture any condensation that may happen. I'm pretty happy with my setup for it. Don't have your exhaust running uphill or it will fill with condensation as I found out and then the thing will smoke out your building really bad.

Thanks. Lots of uses. You mentioned a sap shak. I did about 900 taps a long time ago but I made about 130 gallons of syrup and a bunch of candy. Hope you do too.

The unit is designed to draw in outside air and heat it to prevent negative pressure that would draw in cold air into your shop from outside.

The lock code is for advanced settings it doesn't lock anything else. You can adjust the fuel to air ratio the hertz of the fuel pump. The code is 1688 if you want to see the settings.

I bought one a few years back for my 8x10 greenhouse and it works well during the early spring / late fall nights. I also purchased a length of fuel line and it draws directly from a 5 gallon can. The display brain box isn't the best so keep a spare.

You can hook it up to the 12v output from a power supply out of an old desktop pc

Why not 3D print or build some kind of cover for the intake fan on the back that converts to a 3-4 inch tube and run that into the camper? That way, you are still circulating inside air even if the unit is on the outside.

wonder how much battery power is used...a fully charged battery..how long would this heater last...?

I bought one and put it on my covered back deck. I ran the hose through a 3” hole I cut in the back door. Works great on heating the entire downstairs. Curious to see how much I save on my gas bill.

So have you tried used motor oil or vegetable oil?

It is intended for the air intake to take in outside air. That way you prevent having to draw cold outside air into your heated room. So both the black intake hose and the exhaust go outside so the burning of the diesel and the exhaust it entails basically is in its own outside loop. The internal heat exchanger takes the produced heat and circulates it inside your heated area. What I have seen some people do to increase the efficiency even further is route the exhaust through an old central heat radiator and then to the outside. That way a lot of the heat of the exhaust is also used. In all these are primarily used in campers, rv's, boats. But I have also seen them used in houses as an alternative or even main heating source. Your battery setup would work for shorter periods. But I would combine one with a small/medium solar generator, combined with some solar panels. That way it would work even during an extended power outage. Lots of videos on the diesel use and energy use for the pump/display (battery capacity) on youtube to help calculate your needed storage of diesel for the max periods you expect to use one.

Attention!!! These exhausts will burn a hole through wood or anything not fire proof below it! Be careful and add some fireproofing beneath it. Don’t ask me why I know this! 🤦🏼‍♂️

I bought one 3 years ago and it has been great.

It looks like you had the green fuel line with that unit. Mine ran super rich and built up massive carbon quickly and thew a code. I replaced the green hose with the hard white plastic and has been running great since. Everyone knows the green fuel line sucks at this point so shame on Vevor for still using green fule hose.

I’m going to be very curious about the longevity of this type of unit. We truckers have similar units underneath our sleepers, drawing diesel directly from our main fuel tanks. The units in our trucks cost thousands of dollars, and the only thing reliable about them is that they’re totally unreliable. I’m not sure what the problems with them are, but I’ve always suspected it was an issue with the digital thermostats. Please keep us updated on yours, Todd. If it holds up, it would be something I’d consider getting for my truck.

I have a plan for a large SUV where I want to take the front passenger seat out and cut a hole for the exhaust where the seat sat and route the exhaust out the hole. Obviously sealing up the hole after routing. It would be a nice camper suv.

If you use kerosene the heater will last longer, it'll burn more clean

Sounds like trial and error to me but it seems like I have to do everything 3 times to get it right anyway 😅 thanks for the video & great comments as well.

I have 1 and I have a touring canvass tent Although it doesnt get as cold here in Australia we do get frost so cold enough .Ive used mine only problem is its noise when your camping with other campers .But it heats the tent up really well

These heaters are awesome! Heated a 35ft 5th wheel trailer all last winter. It ran 24/7 from october 17th until April 25th this year and i used 122 gallons of Red diesel. On the lowest setting on Alpine mode it would use 1qt for 8 hrs brilliant heaters, would highly recommend them. The Vevor unit is the best make that i have found👍

Somebody in the comments here.... said that the smaller intake hose should draw from the outside air..... keeps the combustion air as a "closed loop". That makes sense to me..... think about it as a forced-air, natural-gas, central heating system that is plumbed into your house..... it draws its combustion air from outside, uses that air for combustion, and exhausts that same air outside. 👍👍👍

Perfect timing on this video! I've been hearing a lot about these heaters and I've been considering one for my camper. Thanks for the up close view of the set up and for testing it for us.

Understand these heaters are 70% efficient at best. 18,000 max.

does it run on veg oil???

It looks it makes a lot of noise.

5:13 "Celcius, whatever that is." Lol. Typical American. About 90% of the world population uses it, but US citizens don't know about it. ;-)

Considering using this for a small greenhouse to keep those overnight temps up.

I just installed one of these that is the same brand as this vid. Its working well, but the heated air has a plastic or strange chemical smell. I have it running outside now in the hopes the smell will be burned off. Has anyone else had this problem. It gagged me out of my house (400sf tiny house) last night. I feel sick if I smell that smell now. Yuk!

When the heater is listed at 8kw, that is 27,300 btus. That is input bus, not output btus. A typical oil burner is around 80% efficient. So 27,300 btus × 80% is almost 22,000 btus. If you have it outside, so your return air is much colder than inside, you are really killing your efficiency.

i mounted mine on the rear bumper of my 28' travel trailer/camper and swapped the stock 1 gallon tank with a 5 gallon slim style military/jeep gas can so I'm not filling it every day/30 hours! by mounting it outside i don't have to smell the fuel.....i did extend the lcd control wire to mount the control unit to the inside through my tail light hole next to my window ac unit i mounted inside my camper.....if i could put pictures on here i would

tractor trailers at least the ones i have used have a diesel heater in the back , in the sleeper cab

Howdy diesel heater community. My unit is running a bit sluggish. I poured lots of different types of things in it to see what it actually can run on but i guess the worst thing a ran in it was synthetic motor oil. Anyway it runs a bit sluggish now and i was just wondering what will happen if i spray some starting fluid in the intake tube while it is firing up ?

I saw that the fuel line is very close to the exhaust and UNSHEILDED ... IMPROVEMENT REQUIRED HERE

👍🙏🇨🇦🇺🇸❤

Did you noticed that the clicking sound from the pump ever turned off? To this point. Mine has been clicking since I got it and just wondering if that ever shuts off at any point?

it seemed like you could hear the diesel fuel pump clicking noise only immediately after starting it. after that it was quiet or at least manageable. thanks for sharing.

DOES IT WORK? ? ? Did it put any heat? You never said if there is any heat coming out.

I'm looking to try this in my 1 1/2 garage, does it heat this space kinda warm? G-d bless.

Does it have a thermostat start which is auto on/off?

I want to try one in ice shanty. So I don't haft to carry wood out,and clean ashes that make a mess. Be easy with gear to bring a gallon of fuel. Than a sled full of wood.

how about using bio diesel? like sunflower oil?

Vevor have near enough no customer support but saying that most Chinese heather's will be the same remember.if you purchase a vevor heather they are 12v not like the others available so can't be reconfigured to run on 24v as most are otherwise they work much the same

Very confusing since you know almost nothing before you operate it ?????

I got one 8kw 2 years ago. Dang thing didnt work right from the start. Wouldn't burn right, wouldnt start. Id have to put either in fuel line and run it before it would start. Have to chole the air inlet to make it fire. I uad to set starting hz at .8 and 1650 rpm to get it to start with out 4 attempts.. But it just wouldn't burn right no matter what settings, lots of popping.. It didn't matter if i ran Diesel or heating oil. Tons of info on settings for the 2&5 kw heaters but almost nothing on the 8 kw heaters. At about 2.8-30 hz i ran for like 8 hrs and had fuel left

i have one of these with the same silver control and i can not get the pump to turn on and prime does anyone know what buttons to get it to prime

i bya one as well are going to use it to heat up my gargae and if ther is loss of power to heat up the living space

heating a garage for sure, I think an amazing use case for this would be the Cheap Geothermal systems that Simple Tek promotes which is a buried irrigation line or PEX and put it down in the Earth with a water air heat exchanger / radiator In summer you can pull cool Earth temps from 10 feet down. and during winter you mount a unit like this behind the box fan and heat exchanger, so now not only are you pulling warmer air up from underground in the winter but then you're also super charging it with additional diesel heat. If your water lines for your Geothermal system are in your floors, you will also be storing that heat energy into the Earth and floors. Lots of ways to do very efficient heating and cooling using a system like this or an AC to supplement simple Geothermal closed loop systems, and those systems are almost always in your favor 10-20 degree advantage in either winter or summer, then just add a tiny bit of AC or diesel heater now you could heat or cool anything. The other way to supercharge a Geothermal system like that is make a hole in the ground, line it with a tarp or get a cistern and drop your closed loop geo lines into a water bath buried underground. Youll be using and storing heating and cooling energy really efficiently in that system.

Should work in clsss8 over the road trucks pretty well

How long will a gallon of diesel last

kerosene heater less trouble you dont need batterie more safe

They work very well just the fuel pumps are loud In them
