Mini 8kw Diesel/12v Heater Review by  

I bought one of these last year and have been using it to heat my small 600SF condo as I only have electricity for heat. 5 gallons of Diesel lasts 5 to 10 days depending on how cold it is, and my condo is a balmy 74 degrees inside when it in the twenties outside. Love it! One thing I did notice and corrected last year, these heaters tend to coke up when run long periods at the lower settings. I run mine wide open until the condo warms up then set it to 3.1hz minimum... seems to not coke up as bad. Then I service unit in the summer with a rebuild kit (costs about $30 - new gasket, new glow plug & screen). I use electric fans and a ceiling fan to push the warm air around...

Well to be honest I am pretty impressed with this little Diesel heater and the price is excellent! Right now it shows a sale price of $128.99 with free shipping! I might snag one of these. Thanks Chris! 👍 .. After looking at their web site I see that they actually have an RV Style heater that has a different housing style and has four heat outlets that a hose can be added on to better direct the heat flow to where you want it to go.

Some run the exhaust through a home hot water radiator before dumping it outside with excellent results.

I bought the same heater and took it apart for an RV installation. Pricewise for an 8KW it couldn't be beat. I've been using it as my sole heater for over a month now and loving it! I feel so much safer with it then running a Buddy heater. Cost wise Propane vs diesel cost I think it balances out pretty close. Vs Propane its a dryer heat and with the blower it circulates much better. I think I can regulate the temperature in my RV better with it also. I am in a 35 ft fifthwheel at around 3000 ft altitude in Arizona. It does get below freezing here at night sometimes. So far, it's done a great job keeping my trailer warm overnight on the lowest setting during nights of below freezing temperatures. My RV is older so it's no longer as well insulated as when new. I've also experimented with running used motor oil through it. I would recommend well filtering it and not mixing more than 25% used oil with either diesel or kerosene. It will run a fifty fifty mix but it gets harder to start. With the thinner mix it starts better and I think you will be less likely to gunk it up! Even at that I wouldn't recommend doing it all the time! A little here and a little there. Just a way to burn up waste oil as you get it.

Your garage is crazy. Like mad scientist type of crazy.

Cool little heater! Thanks NNKH!

Great review always so thoughtful and direct.

Hi Chris. I know a guy who heats his house in the UK with one of these. His name is Tony and his RU-vid channel is named ' Vortex '. You may have heard of him ,as he has some wildly outrageos ebike and escooter mods on his channel. Extremely clever guy from the middle of England.

I bought that exact same heater. It would never prime even after 3 weeks of trying, so I bought another brand that worked right out of the box.

Thanks man for the demonstration

Good to see you Chris

I have a different brand but pretty much the same thing. The heater will definitely take the edge off and make it more comfortable to work but most likely you won't be toasty warm. I really like these heaters and even running at full blast they sip fuel. Great units that are budget friendly. I recommend getting a small fan to blow all the warm air that rises back down to the floor.

Great timeing on this i am in the market for my 2 car garage at home so I can continue with bench top hobbies during winter months.

Definitely agree with the copper line on the unit. I will probably place filters on the unit from a larger fuel tank.

Brother, Awesome Review Thank you!

117$ on ebay free shipping if anyone was wondering

I have a different style one of those I just got to try out. Ran it for 9 hours out in the shop. Will work great for camping. No issues so far but it’s early. They are really cheap.

Great review! Found your channel a few weeks back, as well as Jen's. Excellent stuff! I am full time big truck, fuel hauler now, but started out as big truck diesel mechanic, and watching you work I can tell that you are GOOD! Excellent mechanic, every detail thought out. Very impressive! Might run into you one day due to being in the area and will come over and say hi!

This would be great to help out pre warming a garage with a wood stove ive been interested in one of these for a while and your insight like always has been great

HEY! Good morning Chris and Jen!

Do you think that you could run used motor oil in this? Love the channel

we use these in self build campervans here in europe. drill two holes through the floor of the van. they work really good. way better than the chinese option. you can also use kerosene on them.

These are really simple. I have an espar and it's so expensive to work on at the shop. One year I decided to take mine apart and it just a ignition chamber, an ignition screen and a glow plug and a fan housing. Usually when they stop working it's from carbon buildup in the ignition chamber, or the ignition screen. It will smoke a lot before that happens. But you can buy the glow plug, screen and gasket kit for like $35 for the espar . And those are like $1200 new and to pay a shop to change those will be at least $600 for 20 minutes of work

Not a bad little heater. Chris i found 80s chevy truck with a truck bed camper on it I said that's right up ur alley the camper looks to be in good shape says no leaks plus has that old school look

It is time for new garage Chris new lift more space, floor heating some good staff

I have a little different one but I attached it to a board and ran the inlet and outlet vents through the board so if my power goes out in the winter I can open my window then close it on the board. The heater sits outside with a 5 gallon can of diesel and a battery and it sucks air from my room, heats it, then blows it back in. It's basically the opposite of a window air conditioner. I also have a small solar panel and controller I can charge the battery with for an extended outage.

Great info 👍 THANKS FOR SHARING

Cool video very informative

Best part for me was when you said " lots of info in instructions manual " I was thinking you meant to say " fark me, this is long lol"

It's a cheaper version of an airtronics heater in a semi tractor. Usually espar or webasto. But for that price, it's great.

Them lines are good. We have them units in all our trucks and they have that same fuel lines. We have never had to change the line's in over 5 years. But anyway we have them units running constantly when we are not driving. They will cook you out if you don't keep them turned down after starting up.

I've been running those heaters for a couple of Seasons now you get about one winter out of it before you need to overall it new glow plug and take it apart and clean all the black shit out of it but they do work very good they seem to be very efficient and do not draw much power the downfall as you got to overhaul it every season

The diesel heaters are good, I have this same heater and they aren't actually 8kw the Housing design is the same for the 5 kw and 3kw and those new controllers suck if you are into tweaking the hz and fan speeds, changed ecu and controller on mine. But for that also depends on your climate, it gets -30c here so dialing it up helps. But all and all they serve their purposem I use one for my ice shack and heating the porch at the house in the winter

Be aware that the output is very often a “ bit “ optimistic.

I have the same unit, I use it in an uninsulated garage about the size of yours. It helps, but I want to insulate the garage. I'm running the exhaust outside, and there is definitely heat loss.

I use this exact heater to heat my 20x22 garage. No issues heating to 69 using the built in thermostat.

Don’t know about pricing in your area , however, in Ireland kerosene is cheaper than diesel and they actually run cleaner on kerosene.

Mine leaked like a sift from the fuil tank fitting.

Even if you insulate a little at a time it will start to help and take less energy. If you heat the garage about 60F degrees it's usually comfortable to work.

I’m curious how it would heat a room with the exhaust vented outside of like it’s supposed to be

Been thinking about one of these what would be a good alternative source for 12v besides an expensive battery.

I just bought one - vevor 5kw for my mini van haven`t set it up yet but hope to use when i leave South Carolina to Arizona after October 20th. Can`t wait to hit the road :-o

That is basically a portable version of a bunk heater used in OTR semi trucks. Those tend to fail because of the fuel pump or ignition failure. Really need to be sure to use clean diesel fuel or a fuel filter, on the trucks they feed straight from the fuel tanks and for some reason don't use fuel filters.

I have exactly the same heater from Vevor with the same display. There is an issue with the manual and the current controller software. You can't access the settings the way it's described in the manual. I guess they have made some sort of upgrade. The problem is stepping from the first setting (clock/timer) to the next. There is no way to get past this first setting so you never get to the rest of them. The manual describes another software version. For example the display is always on now. You don't have to press any buttons to light it.

I been watching for a while just now seeing this weird.. but im going to install one in my 6.5 suburban I’ll upload a video and use the exhaust from it for a block heater sort of speak.

It would be interesting to see the CO levels in your garage when it's running. I'm thinking of this for my garage.

I would prefer to smell something dangerous than not smell it, but the exhaust could be put out a window or something, looks like a handy heater, all the best to you and your loved ones

I’ve been wondering if I could use one of these things to heat my little cabin.

I think I would cut a short slit in the exhaust hose and use two pipe clamps and high temp sealant to secure it and keep it from leaking carbon monoxide into the building. Doesn't hurt to be safe.

Should carbon monoxide detector be closer to the floor or eye level since it fills from floor up?

Hey mate how do you make the screen brighter please

No way to change the display to Fahrenheit vs Celsius ?

Is there any safety features regarding accidently knocking it over? Will it shut off or just keep running while spilling diesel everywhere? Just a thought as the old kerosene heaters used to have a shut off if it ever got knocked off level.

you are right carbon monoxide is ouderless ,so very dangerous, my household co alarm does not trigger, but my gases tester goes crazy with alarms sceaming.

Some clever chaps on RU-vid have reduced the pump noise dramatically

You can buy this heater in France for 180€, in the US you can get it for under 130$🤬🤨. But,i think,i wanna buy one🤔😃. Thanks for your video👍👍.

I wonder if a diesel oil mix would work in there? Good way to use some used oil

RedneckComputerGeek, is doing a similar experiment, with a similar heater, but he has his heater outside and it's ducted into their master bedroom. I wonder what would happen, if you were to try to run one of these on waste oil.

carbon monoxide alarm needs new battery ?

If in the garage, eletric bill way cheaper but in vehicles okay, mini wood stove free almost

I would have won this item on The Price is Right because I guessed $169 before looking at the listening :-)

Saw a dude from europe had a review of one that is similar. The one thing he found out was the 12v at 40w is a bit of a lie, the glow plug in that case pulled way more, dont remember how much more. The other thing I learned from that one some countries over there it is illegal to have a waste oil heater.

8 kW (27500) BTU is an overrating. Most of these take around 0.35 to 0.4 l per hr, around 1/10 gal per hour. Which is around 4 kW.(13500 BTU) That makes sense, as these are copycat Eberspacher air heater, which came to market, when the patent protection ran out. And these were rated at 4kW. Still, it's a good heater for the price These things can be useful in power outages, a small hole in the wall, a capable battery, like 80 to 100 Amp hours, and it might run up to 30 hours on the battery with like 2 gal of Diesel/ kerosene (JetA1) or light fuel oil. And prevent your home from freezing.

Did that exhaust melt your work bench top?

How much of the heat increase came from the exhaust

Thank you for running the unit for an hour and a half with the unit unvented/indoors... I didn't hear your carbon monoxide detector going off! I was surprised. Thinking of getting one of these units to blow hot air UNDER our RV in dead of winter to keep pipes from freezing. It will not be exhausting under the RV. We are full time RV'ers. Thanks for the video.

Nothing fits in mine have to remove everything and put it on the outside to get to work so just buy the one without the case. That's case is useless!

Carbon monoxide is heaver than air. The sensor needs to be closer to the floor.

I never read the instruction’s 😂

You have way overgrown your place about 3 yrs ago..

Good.jop 😄😄👍👍👍👍

Anybody ever try running one of these on waste oil?

Where is the fuel filter? -does it even exist?

As a South Floridian, I don't know how you work in weather that cold!!! Maybe you get used to it?

Carbon monoxide detectors are suppose to be low, like outlet level.

I'm not sure if it's the same brand. But. Forestry Forest has used one of these to heat his van for few years now. He lives in a van. He said the only problem he had with his, was the pump was noisy, and would keep him awake at night. "Went & Checked" His is differant. His fuel tank is bigger, and he has it mounted remotely.

Out of Stock oh well.

That’s only 5kw ..it might say 8kw, but it’s not ..

The TALKING HEADS had Decades ago a BIG HIT singing about this. ( " BURNING DOWN THE HOUSE " )😜

hi

I don't believe that there's any difference between an 8kw and 5kw diesel heater. It's a marketing scam to make you think you're getting a more powerful heater. Like most things made in china, their 200,000 lumen flashlights, are so far from the truth is laughable.

Get some fuel in it!!

Have the same one and it won't do anything.

I'd def be adding a heatshield between the nylon hose and exhaust here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zUbxcbLrUt8.html

that plastic around where the heat comes out has to give off some toxic shit

It's absolutely useless without a thermostat, that's ridiculous a heater without being able to control the temperature. It's just useless junk!

Disappointed on your review. You kept bragging at the temp rise in the garage flailing to mention most of the heat that was produced should have been vented to the outside air.
