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

Sorry but item was larger than expected and will not fit where I intended it to so cannot be installed. Haven't decided what to do with it yet

In our previous caravan we had a 5 kW Vevor heater which heated. So a little surprised and disappointed. much quicker and was quieter when operating

I bought two of these, unfortunately after running one of them through about 10 gallons diesel and I started have black smoke come out of the exhaust, I thought it may have been because of a spill, but I have not yet figured out why it’s doing this however it’s frustrating!! I have not tried the second one let.

Not bad

Das Gerät ist in Ordnung. aber wenn man auf volle pulle laufen lässt zeigt er zwar 20 grad an, nach 10h , der tank ist leer und es hat tatsächlich nur 12 grad aber besser wie frieren

This thing makes heat, but don't let anyone fool you into thinking it will heat a 2 car garage. Max air temperature I measured was 180 degrees. This will keep your dog house or chicken coop warm but not much else.

The heater its self works great, but the controller is way over engendered 4 buttons do everything and is extremly hard to operate. The instruction manual need to be scraped and redone

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

When I got this item, the shipping was quick and came with everything I needed. When I did the initial start-up, the oil pump was unplugged, and I had to cut into the case to plug it in since the unit is riveted to the toolbox. The installation in my van went great. Travelled to Utah and Tahoe over the course of 2 weeks and had to use this to stay warm. I'm powering it off a Bluetti AC50 power bank and can get ample run time on this before needing to recharge. I only used this unit maybe 7 or 8 times before it started blowing smoke and not heating well. After troubleshooting i now need to remove the riveted heater unit and clear/replace parts, which is going to be a pain in the ass considering I just installed this 3 weeks ago... good unit but poor quality in performance. After reviewing the QR code videos on google drive ill have to uninstall it, dismantle it, clean/ buy parts, then hope it works as intended afterward. I recommend it for light uses or in an area where you don't need to uninstall it after less than 1 month of use.

While the unit over is pretty nice and does work it is no where near an 8K heater whether you are measuring input or output. An 8K heater should produce (or consume depending how it is rated) approximately 27,000 btu per hour. I was heating with an adjustable propane heater with three level at 15,000 btu, 30,000 btu, and 45,000 btu. Generally I use the 30 or 45 setting to heat the room up and then kick it down to the 15 to maintain temperature. Generally even the 15 setting is too much and I have to cycle it on and off every 30 minutes or so. I though this heater would be perfect as I could run it on high to heat the room then scale it back to maintain temp. However, on high this raised my room temp about 2 degrees per hour. On low (15,000 btu) my propane heater raises it about 4 degrees per hour. So next step was to look at the fuel consumption. They claim .36 liter per hour and diesel has an energy density of 35,000-36,500 btu per liter. This equates to 13,140 btu per hour at best. Considering there is a heat exchanger with external combustion the efficiency of this unit is probably 80-90%. Once again going on the best case this leaves us with it being close to a 11,800 btu heater or a 3.5K heater.
