HCALORY 12V Portable Diesel Air Heater, 5KW All-in-One Diesel Parking Heater, Parking Bunk Heater with Remote Control, and LCD Monitor for Car Trucks Boat Bus RV Motor-Homes and camper

Item arrived busted. The Shell was cracked around the large intake and at the top of the case. I contacted Hcalory Customer Service with pictures of the damage. Less than a week later I have a Brand new COMPLETE All In One Diesel Heater setting on my front porch. Hcalory owed me a New un-damaged Case Shell to hold the Heater BUT they went above and beyond and replaced the entire purchase. I chose Hcalory, over the numerous other choices, because of their many 5 Stars reviews. My initial 2 Star review has been raised to 5 Stars...thanks to excellent Customer Service. I plan on purchasing a few more of these and they will definitely be Hcalory. The heater puts out very warm air. I purchased a Splitter and extra Hose. This little heater does an excellent job. It puts out more heat than I thought it would. After the initial heating of the rooms, I put it on Low and it maintains the rooms at 68. Better than I expected. One room is 14x20 and the other is 14x14. They are connected by a doorway, I leave the door open and both rooms stay warm with an outdoor temp of 28-35. I am impressed and will purchase for other buildings. My only Con is the App. You have to STOP the ON switch exactly at the right time...all the way to the right or it will cut off after it gets warm...says it's Overheating. Be sure and turn it Wide Open when starting up. This remedy's the Overheating cut off. 6 Stars for Hcalory Customer Service !!

I purchased the HCALORY 12V Portable Diesel Air Heater, lured in by its promise of an 8KW output and easy use. However, I must express my profound disappointment and concern regarding this product.Firstly, the advertised 8KW output is grossly misleading - the actual output is closer to 5KW. This discrepancy is not just a minor oversight but a significant misrepresentation of the product's capabilities.The assembly process is another area where the product falls short. Contrary to the Amazon listing, this heater requires extensive assembly, which is not mentioned at all. The installation is far from straightforward; it's not a simple 'screw-together' job like you'd expect from an Ikea product. Instead, it involves dealing with fuel lines, drilling holes, and fishing fittings into a fuel container. While I am comfortable with such technical tasks, I fear many buyers will quickly find themselves out of their depth. This isn't just an inconvenience; it poses a serious safety risk. Incorrect installation could lead to diesel fuel leaks, which are hazardous.Moreover, the package arrived with absolutely no instructions, leaving users to figure out the complex assembly process on their own. To make matters worse, there were missing parts, which further complicates the installation and can lead to improper assembly, heightening the risk of accidents.The quality of the heater is another concern. It's very cheaply manufactured, which raises doubts about its durability and safety standards. Such poor construction in a device that deals with combustible fuel is alarming.In conclusion, I cannot recommend the HCALORY 12V Diesel Air Heater. It's not only falsely advertised but also potentially dangerous due to its complex installation requirements, lack of proper instructions, missing parts, and subpar manufacturing quality. I strongly urge Amazon to reconsider listing this product, as it poses a significant safety risk to consumers.

The biggest thing I'll call out is the electrical because it's not clear on youtube. Don't expect to be able to use DC power unless you are hooking up directly to battery terminals. The solar generators / portable battery units like jackery and ecoflow only have cigarette lighter outlets which are rated for 120W aka 10A @ 12v. And the demands during startup slightly exceed that. Yes some of the time, for certain battery units, you may not trip the breaker, but if you want a reliable works-every-time setup with a solar generator, you're going to need to use an AC adapter and enable your generator's AC inverter. I got this waterproof one https://www.amazon.com/Waterproof-Transformer-Voltage-3-Prong-Computer/dp/B07Y61R8SRSmall nit-pick, I popped the electrical plug out and flipped it upside down. The way it came from factory, the right angle plug faced toward the ground and was difficult to get in/take out. So I rotated the plug in the case.The 5L tank that comes with it is not mounted flush with the ground which means it wants to tip. I've ordered a 10L tank which this unit does have mounting holes for, but I'm not sure yet if the holes will have the tank flush with the ground, hopefully they do otherwise I'm going to have to drill new holes in the case.The controller doesn't come with a wire long enough to use it as a thermostat, but it's a standard 3-pin plug (the kind you see in a computer case that powers fans) that I'm sure you could buy or make an extension for.The case itself is thin and flimsy, but after being closed up it's fairly rigid. It wasn't clear from youtube or the pictures but the case has a ton of ventilation, there are grills and openings on every face except the handle surface on top. For that reason I felt comfortable moving the small air inlet filter inside the case so it was one less thing sticking out.I didn't attach either of the brackets to the outside of the box for holding the exhaust and intake hoses fixed. I want this thing to be able to sit in my trunk with all my other gear. So I just slip fit the exhaust on when I use it, and keep it stored in the tank when not in use. And my intake is mounted and ziptied right inside the case.The small bracket that holds the controller/thermostat onto the outside is really loose for some reason. I also couldn't determine if it's waterproof or not. So I flipped the bracket around and mounted it through the factory holes from the inside of the case and I keep the controller in there. I'm definitely going to make/buy an extension but it seems to work fine inside the case in the meantime.The controller works well, the app is glitchy but works alright-ish but the remote works great, so no big deal.I've ordered an AC C13 port and I'm mounting the AC adapter right inside the case and wiring it directly in, so I'll be able to power it via DC or AC by plugging in the right cord. I also ordered exhaust wrap, I already started melting a wire where it touched the exhaust hose. Finally I wrapped a 4" hose clamp around the body of the muffler and bent the excess clamp material to form 2 legs, so that the muffler's weep hole is elevated off the ground and facing down.I've gone back and forth on the diesel tank mounting location. I don't like the exposed fuel line that comes with exterior mounting, but I've also spilled diesel (using one of those spillproof nozzles, go figure) filling it almost every time I've gone to fill it, and I would rather that happen outside the box than inside. So I've landed on keeping fuel outside of the box and just working to ensure I mount the fuel line in such a way that it's not very exposed (such as how KeeganBuilds does his)I'm also replacing the cap (which has a vent hole) with a solid cap that has no vent, and then drilling a dedicated vent cap that I can screw/unscrew. That way diesel sloshing around my backseat doesn't drip out of the vent.-----------------Final thoughts-----------------Out of the box, aside from the power draw being too much for solar generators, I think this will definitely do the trick for at least one or two nights a year. The components all work nicely and it wasn't too painful to put together especially after watching a few folks do it on youtube. And for the price you really can't complain, it's a complete kit with basically everything you need pre-assembled in a pretty small package. I got it mainly because I was on a time crunch and wanted to have it for an upcoming trip in time, and it definitely did its job well.But if you plan to use this often, expect to need to make lots of modifications. It doesn't pack or store well unless you fully assemble/disassemble it each time. It doesn't seem very rainproof out of the box. The remote doesn't extend into your tent. It may or may not work off your solar generator. The vented cap will leak if the tank is tipped over or sloshed heavily. The fuel line is very exposed with the default mounting position. The exhaust is hot and easy to burn yourself, if you have kids it's definitely a danger.If I were starting over I would probably buy the parts that KeeganBuilds used for his and build one just like this https://www.youtube.com/watch?v=lKwzue3poDABut given that I have this unit, it works well enough currently that I'm not going to throw it out and start over, but instead slowly work my way closer to the KeeganBuilds setup
