VEVOR Diesel Air Heater 12V 2KW Bluetooth App LCD Display for Car Bus RV Indoors

If you're reading this, you know there are a ton of options. I agonized for days and selected this one. Chose something I could use Amazon Prime on and have a free return if it didn't work out (thankfully and happily, not needed!). I got this for my snowmobile trailer. We ride on week long trips and we pull 3 icy/snowy sleds into the trailer, slam the door and they sit and steam and then turn to bricks--a solution was needed. Looked at propane, but then found these. Diesel is good for 137,000 BTUs per gallon. Propane is only 91,500. So it makes sense that you can get more heat out of less fuel...Unit arrived nicely packaged with all the parts, nothing missing and she fired up first try (after priming). The one nice surprise was that this kit does include the key-fob remote control! It's not in the picture, but it's in the kit!My trailer has electric brakes and a breakaway brake controller that has a small battery. It takes power from the car when you're driving to get charged. The heater needed something bigger and I went with a Group 27 Deep Cycle battery. I then wanted to augment the charging using 120V AC. So a friend recommended this Converter/Charger (https://www.amazon.com/gp/product/B004LF4SFS/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&psc=1). Installed an external plug (https://www.amazon.com/gp/product/B009ANV81S/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&psc=1) and while I was at it, figured having a couple outlets would be nice too.That charger is a 3 stage charger and trickle charger. I ran the charger directly to my G27 battery. I connected the heater directly to the battery as well. I then ran two wires to my trailer lugs where the harness comes in (it has a seven lug connector which made it simple). If I'm towing, I can have the heater on and it's getting power from the car. If I'm in a parking lot, it can run for many hours off the deep cycle. When I'm home or in West Yellowstone, I plug into a power outlet.I've run the unit three times so far. Starts right up. You want to let it do it's own shutdown. You'll hear it power up to full temp and then it cuts the fuel. It takes a couple minutes to run the shutdown sequence, but this burns out any remaining fuel and keeps it running cleaner...do not just cut the power to it.The exhaust tube is 300-400 degrees. I made a simple metal flange out of thin galvanized pipe I had laying around. It insulates the wood floor from the high heat. It read about 150 degrees while the exhaust pipe was over 300.The control panel stays on all the time. I'm thinking of installing a cut-off switch to it so it doesn't parasitically drain my battery if I unhook all power (car or 120v). The connections are fool proof...every connector is a different shape/size so there's only one way this can go together. The ground wire is very short (18") (was wishing for more--and could have added more if needed, but it just reached my batt), but the hot line has an inline fuse (very nice touch) and is very long (3-4ft).I used my infrared thermometer and reads 160 degrees at the duct. The fan is reasonably strong but it's not going to win any prizes, but it had my 20 ft trailer up to 65 degrees in a couple hours.Fuel use is incredibly miserly...I think it might have burnt a quart in four hour run on max...amazing!The first time you run it, use the prime function (the manual has a section on this). That will get the fuel from the tank, thru the filter and up to the heater. As soon as you see the fuel in the line get to the heater with few bubbles, turn off the priming. This also lets you check that your pump is working and installed in the right direction. My manual has a picture of the pump installed in the wrong direction...The wire plug should be towards the heater, not the tank. Once priming was done, I just hit the power button and it warms up the glow plug, then starts pumping fuel. You'll hear it start up (like a tiny jet engine). It takes a couple minutes for it to warm up and produce heat--remember, it is simply moving air over the fins around the combustion chamber...takes time for the metal to heat up.The manual is pretty bad, but if you read things a few times and you have a little mechanical knowledge, it will get you there...I still have to figure out the control panel. I would normally knock one star off for this, but overall, I like this so much, I can't. I just use it set at 35C (max) and turn it on or off. It's about all I need. Seems to burn really clean (esp since it's on max). I suspect if you try to run it on lower fuel settings is when it might cool off and not burn as cleanly...makes sense. If you do that, run it at max power for a few minutes and then shut it down. Hope this helps you...I know I could have used this info...

I bought this because it is far less expensive than the name brand heaters and it does the job.I was disappointed to see that the system includes a digital thermometer but it doesn't turn the heat on and off automatically. I later realized that is probably due to the heater needing to go through startup and shutdown cycles which take several minutes to complete. Heating a small space would require the heater to shut off and turn on so frequently it would be annoying. I have no problem with controlling it manually, and this heater comes with a little remote that lets me turn the heater on (and adjust the temperature settings) while I am still in bed in my van. That eliminates having to get out of bed on cold mornings, which is awesome.Installation is kind of complicated and the manual could definitely be better. You have to drill 2 fairly large holes through the floor of your vehicle, one for the exhaust pipe and the muffler, and the other for the air intake from outside. The fuel line is very close to the air intake tube near the hose clamps so things are very tight there. I connected the fuel line, filter and fuel pump to the auxiliary fuel line on the main tank of my old Sprinter van. While the heater is running the pump makes a tick, tick, tick sound and the exhaust sounds like a far away jet plane on a runway. It isn't all that loud, but it will give away the fact that someone is in the van while stealth camping if anyone walks by. I imagine that would be true for any diesel heater.Inside the noise made by the heater depends on the temperature setting. On the low setting it is easy to forget the heater is operating. At higher settings the fan noise is obvious, but it just sounds like a fan and doesn't really bother me. The fuel consumption seems surprisingly low to me. On the low setting it appears to run 16 hours on a gallon (4 liters) of fuel. On chilly days I get by running the heater 30 minutes on then 30 minutes off. On cold days (near freezing) I run the heater at the mid setting and it can take 2 hours to warm the van till it is toasty, then it is 20 minutes on and off. I have a huge extended van and the amount of insulation one has will affect these times.A common problem with diesel heaters is soot buildup inside the combustion chamber and exhaust. This shows up as error code 8 on the display when you go to start up the heater. Sometimes you can just wait 30 minutes for everything to cool off then start it up again. If that doesn't work, I have found the easiest solution is to remove the filter on the air intake tube under the vehicle, turn the heater on, then use an air mattress air pump to shoot short blasts of high pressure air into the air intake tube. This blows the soot out and helps burn away what remains inside. It can be a dirty job, with the white smoke being loaded with soot, so try to stay out of the smoke.After 1-1/2 years the fan on the heater started making unpleasant noises, so I contacted the manufacturer. They took me through various testing routines over a period of about 10 days, and I discovered hair and dirt had built up on the fan behind the air intake inside the van. Cleaning that helped for a few days, but eventually the motor stopped working and the display showed the code (5) for a motor fault. The company sent me a replacement free of charge without requiring me to return the damaged unit, and the new unit arrived within 5 days. I am very impressed with the customer service.If I were going to do another van build, this is the heater I would install.

Big thanks to another reviewer who pointed out you have to hold the up and down arrows to prime the pump. The instructions were mostly incomprehensible. Watch a few youtube videos before installing.Tips: Use a 5 gallon yellow diesel can instead of the included tank that you have to drill and may or may not leak. You can buy sheets of fuel safe gasket material to insert in the gas can screw on ring (take out the nozzle), poke a hole in it, and send the fuel line to the bottom of the can.Wrap the exhaust in fiberglass heat shielding or similar if you're running it close to anything.It's not loud even without the included "muffler". The fuel pump does produce a clicking/tapping sound so keep that in mind when mounting.Don't get the four vent model expecting it to come with enough ducting. You'll have to jury-rig something. Some dryer vent hose is high temperature enough.The unit will burn through a 5 gallon can of diesel within 48 hours if left running. Hard to know how it compares for cost efficiency versus a propane heater.If you're tying this into another 12v circuit on a camper, it can make lights flicker every time the fuel pump fires (maybe every half to 3/4 of a second). While the amp draw isn't crazy, maybe 6 to 8a, the instantaneous on/off is noticeable when there are lights on the same circuit.Overall I'm pleased with this heater. Just make sure to watch some videos and be prepare to improvise.

Die Heizung lief am Anfang zwar recht laut im Vergleich zu meiner alten Heizung aber das hätte ich akzeptiert. Nach 2 Stunden ging sie von selbst aus, startete aber sofort wieder. Nach ca. einer weiteren Stunde stellte die Anlage sich selbst auf die niedrigste Stufe und ließ sich auch nicht mehr höher stellen. Nach einer Stunde Pause habe ich sie wieder gestartet und das selbe passierte wieder. Danach ging sie immer öfter aus. Jetzt läst sie sich nicht mehr starten. Da ich schon zwei ähnliche Heizungen habe die sehr gut funktionieren. Bin ich sehr enttäuscht. Der Support ist auch fragwürdig ich werde ständig gebeten Videos zu senden, ist halt die übliche Hinhaltetaktik. Ich würde sagen nicht Kaufen die Anlage scheint nicht ausgereift zu sein.

Alles Top. Karre wird warm, alles prima
