Customer Reviews for VEVOR 3KW Diesel Air Heater 12V Diesel Parking Heater Muffler Diesel Heater with Knob Switch for RV Bus Car Motorhome Boats

Works like a champ great quality. Will be a vevor customer for life 10//10 would recommend to a friend

So my heater just arrived today. THE GOOD: It is currently running and being used to heat a work room I have back in my garage. It takes a few minutes to heat up as expected, but is doing a decent job and is actually very quiet. Actually I find the loudest part of operation to be a click sound from the fuel pump each time it pushes fuel. It isn't loud but because it is a repeated sound, I do notice it if there is no music playing or other sounds. I normally have music or something playing back there so that isn't an issue. THE BAD: Take the cover off your heater when it arrives and inspect yours when it arrives! I am glad I did with mine because I immediately found several issues. It looks like after the (green) fuel line was attached to the tank, the line was pulled down tight so it could be attached to the lower heater part. There is plenty of fuel line but because it was pulled down like that and stayed that way for who knows how long - there was a permanent kink in the fuel line on my heater. I had to go to a local hardware store to get new tubing. The power / control lines that run into the heater component rest against the outer cover. If you look closely you can see that just from the vibration of shipping etc. it had already worn through the outer most sleeve of insulation. Not an immediate issue but I did wrap this in some high quality electrical tape just to make sure the main insulation on the red wire (normally denotes POWER line) didn't get rubbed through. Not shown but there is a square cut-out in the metal between the top (where fuel, fuel pump, display is) and the bottom half where the heater proper is located. The fuel line and that power line, both shown in the other pictures, run through that hole. The edges of that square hold / punch out were SHARP. Let me put it this way, those edges are sharp enough that when I rubbed my finger across them I cut my finger (not badly but still). I ended up taking some aquarium air hose, split it down the center, and put it on the edges so I won't have to worry about the fuel or power lines vibrating against it and ending up shorting or causing a fuel leak. So in the end I am giving a 5 on value and ease of use (in general). Features is only 4 stars but then again, I did get the basic version. Quality is only a 3 and that isn't so much overall quality or how long I believe the unit will last but more about the issues I discovered and had to correct before first use.

Great heater, fired right up heated up boat on the hard in 5 degree weather, works well, efficient, quiet

Works great il buy another like having the ability to start it in the garage and start warming up before I go out

Started up normally the first time, however on subsequent starts it smokes badly and errors out. It will start after being reset and eventually runs fine after warming up. NOTE THE FOLLOWING. I have an extra long exhaust and my installation is abnormal in many ways. I suspect that the smoking is due to my own skulduggery which is NOT the fault of the equipment. My 4 star is only because the instructions are really minimal. At $90.00 I may order a second one just to see how it works and for parts.

I use this heater in Denver Colorado other brand don't work well at our altitude. This heater got used well last year 2023 it's mounted in a 16x8 box truck that's insulated and on LOW it will turn box into a sweaty lodge when heaters running you can not close rear door it's awesome keep equipment warm. Uses about 1/3 gallonish 8hr run. 5kw with Plateau module vertical with bluetooth.....At the end of last year we did nothing left old diesel inside tank and walked away. This year 2024 I started heater and with last years fuel it started up and has been working perfectly..... If your thinking about a diesel heater you can't beat these. We had an Espar and Webasto when box was built both within 1 year failed and we spent 300 - 600 dollars on parts and service and the units costed 1000's to purchase new these were I now know complete waste of $$$$ and time servicing then to get them to turn at beginning of year....... Buy vevor heater you'll love it.our box is 16 long x8 wide x7.5 tall R13 insulation. Floor has no insulation just 1 5/8" inch box truck flooring......

So far so good. Build quality seems OK No issues. I added a inline fuel filter, the space is extremely limited. I went with a small 90° style nothing else would fit. Stock pump is surprisingly quiet, although I'm running on the lower settings for my space. A Kodiak truck tent and the tire step set up is hard to beat. Overall I'm very happy with my purchase and would recommend one. Would have went with the stacked unit if I knew how tight the area around the pump is. Long term use and durability will be the question.

Love this product would buy again. One of the best things I have bought to heater up in my house love this.

I am pleased with this heater, its compact and smart looking, I wish the controller display was on a longer cable so you can place it on a display control panel but apart from that it is really good.

Installed this in my van, vented through the floor, connected to my 12v solar system....once you figure out how to get the settings right, its just the push of a button on a remote to turn it on and off, warms up quick and WAY more efficient than a buddy propane heater. Love it!
