Customer Reviews for VEVOR Diesel Heater 12V, Muffler, 2KW Diesel Air Heater, 5L Tank, Diesel Parking Heater with Blue LCD Switch & Remote Control for Bus Boat and Trailer

I have set up in garage on cold days with mini splits helps a lot. I setup with an inverter just plug in fill up and turn on.

These are generally very good units: I’m surprised at how much heat this 5k u it pumps out. It keeps the cabin of my boat toasty here in Alaska. Some notes on weak points of these Chinese units: The fuel line is junk and should be upgraded for safer immediately. The priming method in the instructions doesn’t work, so turn it on with the fuel line unplugged, and let the air work out of the fuel line, then quickly connect the line to the unit. An in-line bleeder valve would be very convenient to assist in bleeding/priming the line because it will need to be done every time you run the tank out of fuel. To insulate the exhaust, parts store “header wrap” works like a champ. These heaters have a few mechanical weakpoints that fail in time, but the components are readily available and easy to work on. The fuel tanks are bulky and in my application I found a different one that took up less real estate and worked better, here on Amazon. Shockingly good heaters for $125!

works very well for my garage lot better than kerosene heater or blower and a lot quieter wish i would have purchased one years ago building is a 12x16 stays very comfortable at low to medium depending temp outside

Upon receiving the unit, I was faced with issues to make it work. Although the unit seemed very well built, it was not starting properly. I contacted the support via email and a replacement controller was immediately dispatched. Since then it’s working flawlessly.

Great little heater. Great fit for my utv. Simple to use and works flawlessly. After adapting to my utv. This thing does a great job keeping the cab warn and defrosted. Excellent equipment at a great price.

This heater was very easy to install; the directions were great! The Vevor Diesel Air Heater All-in-one 12V 8KW Bluetooth App LCD throws excellent heat. My only critique is a that the Vevor heater is a bit noisy.

Very compact and easy to use . Very good on fuel also. I would definitely buy another one. I arrived fast than normal, i live off grid and in a rural area.

Solid product. Some of the hoses seem a little cheap but the actual heating unit does what it says and it does it well. I bought 2 for times without power while camping and for home use when gotta heat a little shed.

Assembly was easy and quick. Once it gets up and running it puts out the heat. My garage is an oversized 1 car, and was able to keep it above 40 degrees F all winter. Running it with a salamander it pushes 75 easy while working on stuff.

You have to love patent expiration.... :-) Seriously, these little guys are great. I'd love to have the ability to set the temperature in Fahrenheit, but heh, its Chinese so Celsius it is. The pump could be quieter (there are aftermarket ones that are) and I'd like the option to set a "deadband" in the controller and have it actually cycle off and back on. I understand why they don't -- the cycle-on (and off) requires a LOT of power to run the glowplug, and killing the battery is a concern. The issue can be that if the "lowest" setting is not low enough you will roast as when the setpoint is reached it goes to the lowest output but does remain on. Having the ability to set a large (say, 5F or 2-3C) deadband where if it goes that much over setpoint it actually turns off, and restarts when it drops back below the setpoint as an option (but not the default) would be nice where one doesn't care about power consumption (e.g. an RV on a shore cord.) With that said -- I've put several nights on it now in my converted trailer in freezing and below temperatures and I'm stunned at how little fuel this thing consumes for the warmth it puts out, and the miserly drain on the battery bank (once running) for the fan. There is a serious concern with the muffler included in that it is not sealed AT ALL and thus leaks exhaust all over the place which, if its under the cabin, can lead to serious trouble. That's fixable with either an aftermarket (again) muffler or some high-temp (e.g. exhaust) sealant, but this really should be addressed by the seam being fully-welded instead of tack-welded. Be careful going through anything potentially combustible; the exhaust side pipe can exceed 500F (IR thermometer verified) which is an obvious ignition risk; ceramic wrap or a dual-wall pipe is necessary; fiberglass (such as is used on a motorcycle pipe) wrap is NOT sufficient. *DO* have a CO monitor just in case. I also replaced the fuel tank with one that has a vertical standpipe and top exit -- the included one is serviceable but anything with a fitting on the bottom is begging for a leak eventually. Diesel stinks and leaks are bad; this should be addressed. I like the remote -- it works well -- but I do not use the bluetooth app as its not an official Android "Play Store" app and I don't like sideloading things; there's just too much risk. Vevor should submit to Google's store for the Android devices so it can be loaded directly without bypassing security. One star off on "features" for the fuel tank design, no Fahrenheit option and leaky muffler, all of which I corrected. I have no idea what durability will be like but I have taken a look inside and there's really not a lot to these things. This one has altitude adjustment built in so it shouldn't run "rich" (and soot up) at high alt.
