Customer Reviews for VEVOR Diesel Air Heater, 8 kW DC12-24V, Fast Heating Diesel Parking Heater with Remote Control and Square Color Digital Display, Low Noise, Voice Announcement, for RV, Truck, Camper, Boat and Trailer

Nobody tells you how noisy the fuel pump is, also when in auto mode you would think the heater would stop heating once it hit the set temperature, instead it just cuts back to minimum heat setting so keeps heating and using fuel but at a slower rate. It does seem to be well built and rugged

Used it twice worked great, today got cold again fired up and keeps shutting off. Seems to be igniting issue. Kinda frustrating base used less than two tanks of fuel.

The unit worked great for about two months and now won't even turn on. Would be great if the motherboard wasn't right on top of the burnchamber

PROS: 1) Easy to install and uses only about 1/2 gallon per 12 hours on lowest setting; 2) The timer is easy to use and you do not have to reset it everyday (make sure you keep the thing fueled); 3) Aside from the fuel pump noise ALL of these types have, purrs like a kitten and VERY QUIET fan; 4) LOVE the two different modes of operation (e.g., set temperature or set operating level). CONS: 1) Temperature offset is only programmable from the hardwired controller and ONLY allows minus nine (-9) offset. For my needs need at least minus twenty-five (-25) offset and that is even with the controller remotely mounted; 2) The clock is HORRIBLY INACCURATE and advances 3-5 minutes per day. Would be superb if the Bluetooth app allowed programming features found on the hardwired controller; 3) Altitude displayed on APP is in meters only and temperature in Celcius only; 4) Need to be able to program timer (et al) from Bluetooth app (AirHeaterBLE); 5) The key-fob remote is terribly designed. If you accidentally touch "Off" the unit shuts down and you have to wait about 5 minutes to be able to restart. On the surface this does not sound like a problem until you find yourself fumbling around in the dark (nighttime) to try to increase/decrease the temperature and accidentally shut it down; 6) Need to be able to program clock from Bluetooth all (AirHeaterBLE). NOTES: 1) Overall a great item and could be FANTASTIC with a few updates to the Bluetooth app (AirHeaterBLE); 2) MOST significantly, needs to have the ability to set TEMPERATURE OFFSET up to -25 (minus twenty-five) degrees as the controller shows FAR hotter than actual temperature and that is even after mounting it far away from the heater; 3) The Bluetooth app needs to have an ADVANCED SETTINGS page where all the features can be changed/monitored appropriately. Doing this would be easier than an (impossible) firmware upgrade to the hardwired controller (i.e., those already out in the field). Would purchase again without hesitation, but sure hope they update the Bluetooth app and fix the clock innacuracy (maybe sync to phone time???).

Had to fix line from tank to pump first of all. Never got the blue Tooth to work. My old one actually worked Better.

Melted after a 4 months of use as a tiny house anti freezing measures. Instructions could use work by someone who is fluent in english (Not Slander).

It took 3 diesel heaters before this last one finally worked. What would have cost $250 ish to install via a diesel mechanic ended up costing me over $1200.00 total. Vevor wanted me to make sure my oil and oil filter was clean. It took a lot of going around in circles with customer service to fully reimburse me each time for a product that would not start/light at all, even though fuel was getting to it. The only other product like it is 3-5k which is significantly more and rumor has it they have problems too. Maybe not out of the box though? So I’m happy to announce the third one works and so far so good. It’s only been 2 weeks. It’s great to finally have heat on a cold winters night in the Utah desert. Fingers crossed. Good luck to you all.

Thermostat not dependable but using constant on works fine. Using bluetooth to turn on works but unit will shut down before the night is over. Not good if you are using to prevent water from freezing or heating anything critical. I us this one for heating mu battery room. If i manually turn it on low it stays on. If I set the temperature or turn it on with bluetooth it will work for a while then turn off.

I have only had it installed a couple weeks so i cant speak on the longevity of the unit, but i will say it cranks out heat. I have a 40' destination trailer. I mounted this unit in a tongue box and piped it in the wall. With both my furnace and this running it heats up from 55⁰ to 65⁰ in less than a half hr. The fuel consumption is relatively low unless i keep it running all night in which case it uses about a gallon of diesel. The remote is handy. The bluetooth app is absolute garbage tho. I got it to work once and not again. I also am not sure where the thermostat is located but the auto feature doesnt seem to work either.

Would not start right out of the box. Kept saying voltage was too high when it wasn't. Then I finally got it running and then it would shut off and say something else that wasn't true. Save your money
