Customer Reviews for VEVOR Diesel Air Heater, 8 kW DC12-24V, Fast Heating Diesel Parking Heater with Remote Control and Black LCD Switch, Low Noise, Pre-Heating Function, for RV, Truck, Camper, Van, Boat and Trailer

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

it didnt work when i got it all it did was blow fuses and the wires got hot and i asked vevor for a replacement or refund and they told me i need to take it apart and look at it well im no electrician and i bet most of the people that buy these are not either but i did everything looked good so now they want to send me replacement parts instead of a heater that works or a refund so i guess if you buy something from vevor they expect you to make their product work i have had this heater for almost a month now and still have not been able do to faulty equipment and takes weeks to receive parts

problems with the heater day one fuel pump makes a lot of noise and does not pump fuel I reached out t and they wanted videos and pictures. I sent my videos and have not heard nothing back from them.

Purchased one of these as my old heater went out, decided to try the vevor rather than the espar, got it installed, it worked for about 2 weeks then quick working, it took over 4 months for them to finally replace it. Mind you I boxed up the old one, shipped it off, and it still took forever tk get a replacement. I had to email in twice asking if I was getting even the broken one back or my money or something and after another month they finally said "sorry for the delay" and they would get the new one to me. A month later it shows up. The entire process successfully brought me to the warm season where I dont even need it so I havent even installed this new one. Maybe it works, maybe it doesn't idk. But a warranty and service that takes months is ridiculous.

Worst customer service ever!!! Product threw codes, wouldn’t heat, wouldn’t power off and leaked fuel. Not sure I’d ever recommend this or any other product to anyone. The 30 day warranty, bogus!

The automatic temperature setting is terrible at holding the temperature. It turns on about 5 deg below the set point and doesn't increase the power until 10 deg below the setup point.

The heater's controls are confusing and hard to navigate also the heater doesn't seem to provide the 8kw (27,000 btu) that it is advertised to produce.

The only conclusion I've come to is that there anti gel in the fuel from the gas station as I live in northern climate and that's what's contaminating my fuel making it not all burn it's smokes a lot I've tried turning it all the way up it just made it unusable
