Customer Reviews for VEVOR 5KW Diesel Air Heater 12V Diesel Parking Heater Double Mufflers 5KW Diesel Heater with LCD Thermostat for RV Bus Trailer Motorhome and Boats

These are great diesel heaters! I put one of these 2kw Bluetooth models in my gmc savana kind of underneath and behind the drivers seat. I did use the optional pedestal that uses a five inch hole and mounted the fuel pump underneath the van. I feel that the 2kw is the perfect size because the 5kw and 8kw that I have used are just too many btu. I purchased two more for other vehicles.

Great unit and puts out an extreme amount of heat. The only minor complaint is the exhaust comes out of the bottom and there isn’t much room to run it

this heater is great uses very little fuel oil ive heard the fuel pump is noisy wrong blue tooth app on my phone works everytime if your looking for a great priced heater that works this is for you

This little heater worked great on my recent camping trip in the mountains where nighttime temps were in the low 30s. Ran for 10 hours and only used 80% of the 1 gallon fuel tank and only 20% of my 100Ah camper battery. I definitely recommend for anyone looking for an inexpensive heating solution.

The machine works and does a decent job warming my garage. However, it struggles to heat my shop (24x24) effectively when the temperature drops to 20-40°F at night. Initially, I had trouble getting it to start because my 10-amp power supply wasn’t sufficient. Luckily, I had a 30-amp power supply on hand, and with that, it started right up. Yesterday, I went into the shop to do some work and discovered it was out of fuel, even though I left it almost full (I pushed the button until it displayed "OFF" the other day). I was confused until tonight when I heard it running on its own without any input! After looking into it, I think the issue is with the timer or some automatic setting that causes the machine to start by itself. Unfortunately, the manual is so poorly written that I have no idea if I managed to turn it off, so I just unplugged the power supply to be safe until I can confirm it’s off for good. Another issue is the display—it’s very hard to read and difficult to tell which indicators are lit. Conclusion: The machine works, but the interface is terrible, and the instructions are even worse. How can I replace the current controller?

Everyone has mixed reviews on these but what it boils down to is lack of knowledge. These units work great! Only thing i recommended is upgrading fuel line to the white more ridged line and better fuel filter.

Works great in my camp trailer. Perfect size, heats up fast and doesn't consume much fuel. Well worth it.

I bought this machine with high hopes as every person review online rants and raves about it. At first, I was on board— this machine was awesome. Until about the 3rd night using it and it turned off unexpectedly and hasn’t worked since. I have done every troubleshooting method possible, even disassembled the machine. To no avail. Unless the machine I got was a dud from the factory and I have bad luck, they are not as good as you’d think. But… when it worked… it WORKED.

This is the second diesel heater I've owned loved the first one which was a different brand with zero issues so I bought this one. Has been nothing but a problem will not buy again and gonna throw this junk at a wall.

Bought this unit and it is not working right out of the box. I tried to get support, but Vevor said that it does not qualify for after sales service. Very unsatisfied with this product.
