Customer Reviews for VEVOR Diesel Air Heater All-in-one 12V 8KW Bluetooth App LCD for Car RV Indoors

Love this heater. It keeps me warm all night, burning less than 0.5 gallons of diesel in 8 hrs. Buy it you won't regret it. Buy a 4 inch insulated hose for heating your tent as 3 inch is too restricted.

Excellent value. A few of the included components such as the fuel screen and hose clamps are not of the highest quality but for what the unit costs you can’t expect top of the line and it works great! I have it installed in my enclosed trailer and it keeps it very comfortable even into the high single digits F. My trailer is not insulated either. Can’t beat it, I’m going to add one of the portable units to my collection of things next to use wherever needed.

This heater really works very well in my 14' x 32' shop even in single digits. Your manual could use a little more better translation to English.

Unit will not run not happy with product count as a loss not first time I got a bad product oh well

Fired off first try watched YouTube before starting. If done wrong it will damage unit. Works great using red off road diesel no filter on unit filter fuel before adding was only complaint.

it worked great in the desert Use an EZ up in three sides with one side open. Air temperature was 40°, this heater maintained a 65° temperature in the EZ up until early morning when temperatures dropped more.

I am amazed at how well this product heats given the size and price. I was looking for a low priced option for potentially heating my one stall garage, an enclosed trailer, or small shed. This checked all the boxes. Portable, efficient, and doesn't throw CO into the heated space. I have it temporarily set up on a stand that I am hoping to adapt to these three spaces in my house. I started in the garage as it is the largest space. If it works in that space, it will definitely work in the other two! The garage is an unheated and not well insulated space. The set up was pretty simple. It was 19f outside temp. The garage started at 30. Within 90 minutes running the heater on high the space was 55F. Not a sauna, but the point was to take the edge off and be able to work in the space. I lowered the heater to its lowest setting and after 3 hours the space was 64. Outside temp was 15 at that point. This is with an open window (for the exhaust pipe to stick out). I am very impressed but this little heater! The only downside is the exhaust. It gets rather hot. Have a plan to safely mount the exhaust to get it out of where you want to run the heater. There are a ton of Youtube videos on ways to do this. If you are looking for cheap heat that actually works, you just found it!

great quality product!

The easiest installation ever. I have installed 2 heaters in 2 service vans. Three best way to keep adhesives, seals & other sensitive materials throughout the winter months in Minnesota. Great product easy to setup.

I purchased the Vevor All-in-One Diesel Air Heater with high hopes, given its advertised 8KW of heating power, diesel fuel efficiency, and included LCD monitor and remote control. Unfortunately, my experience has been frustrating and disappointing due to several design flaws, quality control issues, and poor functionality. Initially, the heater seemed to work well, providing decent warmth. However, over time, the performance gradually degraded. The heater started burning colder and offering less heat until it eventually stopped running altogether. Upon disassembly, I discovered that the bolts on the burn chamber were not even properly tightened, leading to significant carbon buildup inside the chambers. This lack of attention to assembly quality is unacceptable and undoubtedly contributed to the heater’s decline in performance. One of the most glaring oversights is that the unit does not come with a fuel filter. This omission increases the risk of contamination in the fuel system, which can lead to clogging and other operational issues. Additionally, the LCD display included with my unit lacked any form of adjustability for fan speed or fuel pressure/pump speed. After researching, I found that most of Vevor’s other diesel heaters include a hidden menu for advanced adjustments, but the model I received does not have this feature. It appears to be the only version they offer that is so restricted, which feels like a step backward compared to their other models. I also encountered a serious safety issue when the glow plug came loose. This caused fuel to leak into the warm air outtake, filling the room with smoke—a hazardous situation that could have been far worse if left unnoticed. To fix this, I had to disassemble the entire machine just to tighten the glow plug. For a product designed to be a convenient and reliable heating solution, this level of maintenance and troubleshooting should not be necessary. Overall, the Vevor All-in-One Diesel Air Heater suffers from poor build quality, limited functionality, and safety concerns. While it’s capable of heating effectively in the short term, these issues undermine its long-term reliability and usability. If you’re considering purchasing this heater, be aware of the risks involved and the potential for extensive maintenance. I cannot recommend this product given my experience, and I would advise others to explore alternatives from more reputable brands with better quality control and user-friendly features.
