VEVOR 3KW Diesel Air Heater 12V Diesel Parking Heater 3000W Diesel Heater with Knob Switch for RV Bus Car Motorhome Boats

Smaller version of the 5kw for smaller places (think half-ton conversion van where space is at a premium) but works just like the bigger one. As with the larger ones I'm not a fan of the fuel tank included (I want a vertical standpipe and top exit so there is no risk of leaks over time) and its larger than it needs to be, especially for the smaller output and thus less fuel use. And I'd like Fahrenheit selectable but I get it -- its EU and Chinese made, so.... yeah, its Celsius. All my other comments on the larger unit apply as well; a menu-selectable deadband and on/off capability for when you're on shore power and don't care about the cycle up/down power drain would be nice. There are aftermarket answers to this problem if you really need it. These newer models with the built-in altitude compensation are IMHO worth it simply for that reason alone; otherwise you have to go into the service menus on the older controllers and derate manually or you'll soot it up if you're at higher altitude. I appreciate not having to do that.

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.
