Great Heater! Good Value.
This unit works great. Puts out a lot of heat. The ticking of the pump was load during the start up but got much quieter when it was running. The manual isn’t very helpful. I got an E10 error when I first tried to start it. I didn’t bother priming. Just unplug it, plug it back in and try again. The heater will prime itself and you won’t risk flooding it. Fired up on the second attempt.

Great buy for the money
Worked right out of the box. Initial startup had a lot of white smoke. After running about 7 min. the smoke stopped and didn't return with subsequent startups. Temperature was very hot. The noise lever wasn't too bad. The clicking of the full pump might bother some people but you can always upgrade to a quiter one for about $25. I'm OK with it for now. Very fuel efficient with the 1.3 gallon tank. Statup costs about 115 watts for about 3 min. After that it's about 33 Watts on it highest fan setting and 9 watts on its lowest setting. The display extention cable is a great feature. Liked this heater so much I bought a second one for my brother. Will write a second review on the other heater once we get back from Yosemite camping trip.

2nd update: run away.
2nd update: it has been weeks and the replacement glow plug that they were supposed to send me still isn’t here. I ordered my own and got the heater running. Now, one week later, I am going to have to replace the bearings in the blower motor because the thing is so obnoxiously loud that unless I have noise canceling headphones in being in my garage is absolutely unbearable. The only reason I am keeping this unit is because I want that temperature control. This purchase has been nothing short of a nightmare. The temperature controls are fantastic, the quality of the heater it’s attached to is on the low side for heaters that are already typically low and quality in the first place. Update: the heater took forever to arrive, arrived with a bad glow plug and not working, and their response a WEEK later was to tell me they are “working on sourcing parts” and will let me know when they find a glow plug to send me from China that will take at least a week to get here. A heater manufacturer… has to source glow plugs…? Definitely time to process a return and avoid them at all costs. It’s a shame, the unit is nice. Love the unit. The case is nice and it has the best quality stock fuel line I’ve seen on these. But after I got it primed with fuel and ready to use, it wouldn’t start with the glow plug symbol on the controller and E031. The manual says it’s the glow plug. I see nothing wrong with it and it tested fine, so I’ll see what happens when I put another one in it. They are sending me a new glow plug, but that doesn’t change the fact that slow shipping of the unit and now I’ll have to wait for a glow plug I’ll have to install myself… I’m irritated. Highly irritated. But I’d rather swap a glow plug than send it back. And after all that, it may end up being the control board. Will they just want to send me a control board and expect me to do that labor for free too?

Worth the price. Purchase "WITH ADAPTER" to operate on a standard household plug,NO Battery needed
Work's great!! Heats up my camper in no time at all (About 270 sqft) Just pay attention to the "With/without adapter" when purchasing. Without is just a12v cord for a 12 battery and "With adapter" it comes with an adapter to plug into the heater and into any 110v wall plug(Regular house plug) I'd suggest a longer Intake and Exhaust hose, The intake hose sucks the air in to heat and the exhaust hose blows the exhaust fumes out and both of these ports are on the bottom so you want them apart from one another. The you have the vent hose that comes out the front of the machine that blows the HOT air. You'll need to make a stand because of the hoses coming out the bottom, I used a little chair made for a little pot planter and it work's great... I 100% recommend and the Bluetooth app makes it simple and you can pop the LCD screen off and mount it inside so the auto On/OFF feature can read the inside temperature. It looks great,has a very quiet tick noise from the diesel pump but it's very faint and after a few minutes you don't even notice it.. It blows fairly hard for the size of it and no louder than your average 12in desk fan that's 10ft away.. All these cheaper diesel heaters are overall the same inside but their customer service pushes this unit over the top!!

Great little diesel heater.
Great little diesel heater. It came fast after I ordered it and it set up really well, and came with everything including the power supply. I am using it for a mobile home living room/kitchen area (350 sq f). I first tested it on Low, and It worked great and only used a tank (3.5L) in 24 hours to keep me warm (20's and 30's outside). -I was surprised how small the tank was when I first got it, and was expecting 5L. I set it up to keep the room at 65, but it wouldn't adjust for the temperature and ran at the same heat setting regardless. So I treat it like a 'wood stove' and just adjust it manually as I need. It works great at keeps things warm! I just wished I could have used the extra features like adjusting the temperature and shutting off and coming on again 'automatically' to stretch the fuel more. -Maybe I got a bad one, or maybe I'm just not setting it up right... You know what? It's just a hiccup. The extra stuff is just window dressing anyway! It does what I need it to do, it KEEPS ME WARM! -It's SO much better than the $200-$400 a month I use to spend on electric 'oil heaters' in every room, or my neighbor who pays around $300 a month to run his "efficient" mini-split heat pump for their mobile home. Diesel heaters are such a God Send, and I love mine!

Works great.
This little heater is great! I have 2 of these heating a large one car garage with a high ceiling and they actually do a good job. Only thing to be aware of is that the exaust does make some condensation. So during install make a way for the water to drain out.

I just received this heater after waiting a few weeks. Right away the LCD display wasn't working properly. Only a few lights and not readable. You cant tell what temperature or any settings , error codes and what not. Its does blow the heat out but using the thermostat is useless when you can't read it. Apparently it's a non returnable item also. Nice to find this out after you purchase it. No way of knowing until you try to return it.. waiting for the seller to respond and hopefully get a refund or im stuck with this. Very disappointed so far. Seller will not respond. Do not buy from GB LLC. Now waiting after 3 weeks of trying to see if Amazon will refund on behalf of the seller . Also contacted the company in China and they said they would ship me my parts but of course the parts were lost in shipping some how. At least the company has replied. Fingers crossed. Will update on refund and or parts. Beware of seller. UPDATE. With a few texts to Amazon associates and going through their A-Z claim, im happy to say that Amazon pulled through and fully refunded me. Happy camper now. Left a seller (GB LLC) review and of course they replied to review saying they contacted me and i complained about a working heater. HCALLORY finally sent a new motherboard, remote and LCD. You can read it. Unfortunately you can't find instructions on their site or YouTube. If anyone has this lcd please contact me. Thanks Amazon and Hcalory but beware of seller GB LLC not Hcalory.
