Customer Reviews for 12V 8KW Diesel Air Heater for RV Motorhome Trailer Trucks Boats 8kW + LCD Switch

After install it works. Consumes more fuel than advertised. We'll see how long it lasts. Hopefully there's no issues.

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.

I really like the heat output and the compact design. I must say the description of managing the controls is less than clear. I still am not sure how to change the settings and could not find anything on line to go over step by step how to change the controls. Also, the fuel pump clunking is surprisingly loud. I am surprised the designers could not silence this better? As well, I think there needs to be more caution on the heat the exhaust pipe generates, it cannot be close to combustible materials, as it gets extremely hot.

It stopped running after 4 weeks. I ran it only at night. I am still waiting on vevor to see if they are going to send me parts or a new one. I think they need to send me a new one but I know that not going to happen,right now I would not recommend it.

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 realize this is my fault for not looking closer but I would think they would in a more prominent way that this only has two wires hanging out the back. I had to grab a computer psu and solder it into the harness to power it. That or pay a couple hundred for a large enough inverter.

I give it the review I did cause it took over a week to get them when unpacked it the top front where handle is all bent up from being dropped. Then we open the instruction manual and the instructions are so jacked up the way they are written i still ain't got it figured out on just setting the time muchles anything else it can do. Kinda a wing and prayer when starting it up... So I am pleased with the heat it puts out but to get it to do just that well that's a total difference story...

I am a mechanical engineer, and the instructions were so poorly translated they make no sense. The instructions are almost useless and need to go on Utube to set it up. Even on UTUBE there are numerous control panel styles, and the setup is different for each one. I did finally get it to work, but I am not sure I could repeat the process. The most important part is to prime the unit, to get fuel into the burner. They would be well served to get someone who is well versed in Chinese and English to do a correct translation. I have other Vevor products, and the instructions were much better. Once you get it going, it works great.

So I thought this was a plug-in play system where you’d hook it up screw it in drill hole plug it in and it’d run but there’s this one other piece which you need which does not come with the kit and that’s the 140 amp to 12 V inverter or so. So I can plug it in without ruining the unit, vevor themselves don’t sell that particular part you’re gonna have to source it out which I did and I’m waiting on it to come I the mail…..

The unit is nice overall. I had to get it fixed because the fuel line was blocked, but once that was resolved, it worked fine. There is a noticeable clicking noise, which is rather distracting, but the unit functions well despite that. I would recommend it, after all.
