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

Purchased to heat my camper shell while hunting in cold fall night temperatures. It works great. Make sure to prime the heater prior to use use. This little heat is very quiet. The instructions are hard to understand but YouTube helped with that. The unit is fairly small standing about knee high.

Seems to work great

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 optionThis 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.

Easy to install and puts out a lot of heat for such a small heater.

I have owned a variety of Vevor items. They make a wide variety of items for garage mechanic use. This diesel heater works great. East to install and easy to operate. It’s a great value and has been dependable. I run it a lot. If it’s 20 degrees out side, I can fire it up in my non-insulated 20x24 garage and get it up to 50-50. If I run my salamander for a few minutes and heat the floors, it will hold at 65 throughout the day. I am sure I could do some things to increase its efficiency and it would be beyond amazing if I had literally any insulation at all in my garage. That will be my spring time project. I get around 10 hrs on max setting and if it’s topped off and running on 7 out of ten, I can get almost 16hrs. I trust Vevor products. I am a small engine mechanic by trade and fix literally anything for anyone. It’s just a part of who I am. I do a lot of diagnoses on evap systems in cars and Vevor has some great tools out to help with all these things and they always have a great price. They have a OBDII scan tool that utilizes the same software as a much bigger company in a super simple setup. I keep it in the glove box and can check/clear codes as well as watch live data or perform bi-directional options such as seal the evap system to check for leaks. Vevor deserves a good hard look when your looking for tools for the garage or shop. I always figure I will buy there tools and if I wear it out, it proves my proof of concept and justification of moving up the tool grade ladder. I still have tons of Vevor tools, but not because of lack of use, but because it’s good quality stuff.

You Me Super Fun Happy Number One Go Fast Now! -Diesel heater tip of the day: Stick a leafblower over the air input filter and ram air through the diesel heater, into the venturi hole and atomizer screen to help start a snuffed out diesel heater when it refuses to ignite and smokes/snuffs out with error code 8 or 10 etc. with the leafblower pushing through it, you'll see soot and sparks then you'll hear air flowing again as it clears out. If there is no sound of air flow in the intake and it keeps smoking and snuffing out, then it is not breathing and needs to be cleared out with a leafblower. The three inch nozzle on the leafblower fits right over the two inch air filter on the one inch intake pipe. Sometimes takes two or three attempts to clear it out if it is sooted up bad. Works great!

Amazing heater! Used this to heat my bedroom and bathroom during the winter. It perfomed with only 1 issue, if run too low the suction collapsed the tank, affecting capacity and how long it will run for. Vevor customer service sent me out a replacement, and I modded to fuel from a metal 5 gallon can I had. This product was a life saver and I recommend it to everyone I know needing heat
