VEVOR Diesel Air Heater, 12V 5KW All-on-one Diesel Heater with Remote Control and LCD, 5L Fuel Tank Portable Diesel Parking Heater, Rapid Heating for RV Trailer Camper Van Boat

For a small space, smallish camper or a pickup truck bed, this is the BEST way hands down to heat. Safer and dryer than a buddy heater. Simpler than propane. Cheap to run, doesn't use much diesel when ran on low, less than half a tank a night. So good I think I'm going to get another just so I always have one in my camper, and a spare in my truck. The clicking from the fuel pump doesn't bother me much, I leave the whole unit outside of my camper or truck and it provides a bit of white noise when I do hear it. If you have a larger camper, say over 25' I wouldn't use one of these unless you only heat one area, they work best heating a more confined space. For the price, and for what you get, it works as expected, the altimeter is even pretty accurate, I take it up to higher elevations on the East Coast (say 3500'+) and it reads my camp at 1.1km.

The Vevor heater is easy to assemble and operate. Took me about 15 minutes to put everything together. You will need a 2 x 4 or something to raise it up off the floor a bit to help with clearance of the exhaust pipe. Once I had it hooked to the 12 V battery powered it on. The initial start took about five minutes before it started producing heat. The LED screen is easy to read, and the key fob is easy to use with power on off function and temperature up and down controls so far so good.

This would be 5 stars if it worked as designed, and 4 if I could get helpful and productive customer service. But since I cant get any resolution to my problem, it's 1 star, zero if that was an option This is the second Vevor product I have purchased, and I've had problems with both, and the customer service is completely and utterly worthless. The heater works, in that it does heat, actually very well for the fuel consumption. Not sure where others are getting so many error codes. I've only gotten 2, one when it ran out of fuel, and the other when I put a duct extension on, and it didn't like that the outlet temp got too hot - and shut down safely, as engineered. If you want to extend the heat outlet, transition from 3" to 4" after the initial connection to the heater, or use a smooth, 100% metal, 3" duct. My primary issue is the heater won't shut down when it reaches setpoint. It will slow down, but not stop heating. I have read others say they had a similar issue, and after much unproductive back-and-forth with Vevor, have gotten new control boards. Not sure if that fixed the issue or not. I have been texting/messaging back and forth with VEVOR for well over a month, sent in a nearly 2-minute video clearly showing the problem. They finally agreed to send a new display (sort of), I asked if that contained the PID (or whatever system they use to manage calls for heat and stop heat), and I then got a follow-up message saying the previous email was wrong and the operation was normal. It's not. No reason to have a thermostat if it just keeps heating, even if it's low heat output. These heaters are intended for small spaces, and are supposed to be automatically controlled when equipped with a thermostat. This particular heater does not do that. I am very happy with the heat and fuel usage. For others that have complained about the noise, smoke, the endless errors, they're either shilled reviews, or they've tried to modify it, not followed instructions, or used bad/wrong fuel. These are basic systems, and they generally all work pretty well (I believe there's only one or two actual manufacturers of the primary burner. They are put in different color/size cases, and they might have a slightly different controller with additional features, but the remainder of it is identical). You can hear the fan and the pump, but that's expected in a unit that produces this much heat and doesn't need an HVAC professional to install it. It does need a decent power supply (battery or transformer), but mostly for startup. Once it's running, it sips fuel and power. There is wisp of diesel smoke out of the exhaust at startup, maybe 10 seconds (you MUST vent to outside the space your heating), and then it's pretty odor free. For context, this heater is in an off-grid cabin, with a 12v power source running off 110v (solar), at an altitude of 7,200 ft. In general it works great if I need quick heat at the press of a button. The customer service has been the worst, though, as in lots of dodging, and mostly a lot of misunderstanding. I will now readily pay more for a product if I know I'll get help when I need it. The Chinese to English translation is bad enough, but the lack of understanding is overwhelming. No more Vevor products, for me.

I love this little thing however once I first bought it it had some trouble starting, once it eventually did it would stall out and die / turn off. Did some digging and fixed it. While I was under the case to fix the problem I found diesel leaking everywhere from the tank.. so that was a mess to clean up. Found out it’s leaking from the drain tap that’s tapped into the plastic tank itself.. still not sure how to go about this, I’ll probably just have to buy another tank I’m guessing since it won’t seal. What was the fix of it not starting? Well a faulty glow plug on the brand new unit.. threw a E03. Once the plug was pulled a crack in the glow plug was found. Reason being for it not starting. Ordered and replaced the glow plug with some kit I found on amazon and now it runs great. I guess it’s you get what you pay for so I’m not angry or anything just a little annoyed. On the bright side, the heater gets hot! Bought it for my little shed I have for when I work in there during the winter months and works perfectly! Of course that is everything I’ve done to it.

So far so good. I've had it a little over a week now. I installed it into my camper as for we have 4 children and I did not feel safe placing it inside. It has gotten down to 20 degrees here in Wisconsin and kept the camper at 80 easily. It does have an auto shut off you can set the temp you want and it will get it to that temp and shut off just like a regular furnace. On the nights that it has been in the 20s i only used one tank in 12 hours so definitely is efficient. I get just about 200 degrees F coming out the pipe into my camper so it definitely blows good heat. Does have a tick to it from the fuel pump but for the price and the heat it puts out the tick is fine. Does leak from the bottom of the tank a little where the fitting into the take is. If your wondering about relocating the screen it only comes with about 3 inches of cord. Is what I did is used some 3 wire cord and slices the connector on the screen side splice together the 3 wires on one side of the connector so I could connect and disconnect the wires if I want to move it i hardwired the rest of the wire to the screen side and put connectors on and such and ran it about 10 feet and it works just fine the only thing I can tell is the the volts it says the batter is at are way lower then it really is but I chalk that up to the extra wire from the heater to the controller. I have ran it like this so far and it works fine. The app works great to see the status of the battery the diesle heater temp also run status and so forth the app is worth it. Going to buy a second for backup or other uses as it seems to work amazing so far.

Fungerar bra

Działa bardzo dobrze

noisy but economical; uses about 4l / 24h on lowest setting, as such heats up big living room 36mm2 with bad insulation, up to 13C when outside is freezing 0 Celsius WARNING would deserve 4 stars but diesel container is ONLY 3,2 liter and NOT 5 liter as indicated on the side panel !!!!!

Hardcore nice machine
