HCALORY 8KW Diesel Air Heater All-in-one 110V AC & 12V DC Support with Altitude Mode 5L Fuel Tank Portable Parking Heater Bluetooth APP Control Heating for Car Truck Boat RV Campers

I watched a bunch of videos about diesel heaters, read all of the comments and took a chance. My experience is that this heater was well assembled and safe to use as it came from the factory. The allegedly junk green fuel line works. There were no loose screws or hose clamps. There were no leaks. I’ve run it flawlessly for 10-12 hours daily for several weeks heating a 14’x22’ room in a garage. Does it heat it up quickly? Not really, but after a couple of hours the temperature has been at least 10 degrees warmer than outside and after that the temperature keeps rising about 10 degrees Fahrenheit an hour. That’s my experience with this heater. The room has a 12’ ceiling, so it’s a pretty good sized space. I have the heater sitting outside the building and 8’ of ducting run through the window into the room. I think it would heat quicker if mounted inside the room and the exhaust run through the wall to the outside but I’m not sure because I haven’t tried it. On the highest setting I think it will run about 12-14 hours per tankful. I use a 50 amp lifepo4 battery to power it. After the shutdown sequence is completed, within 5 minutes the exhaust pipe and heater are cool enough for me to touch and separate for storage. The exhaust pipe is actually cold within 5 minutes . I think this type heater is for people that have some experience with equipment and who enjoy operating different types of equipment. If you expect to plug and play and don’t have any idea of what to do when a clamp needs tightening or how to install a fuel line hose clamp, maybe you should consider another type of heater. Personally , I think these heaters are fun to set up and run and I am not a professional.

Love the idea of the heater and for the 10 minutes it worked, it was great. Then it overheated, error code 05.After altering the setup I had used flawlessly, no errors at all, for my L.F Bros diesel heater, a change of hose, straightening the exhaust pipe, and changing the input through the window, with a little luck, I got it to run for about 10 minutes again.I turned it off for the night's testing, but when I attempted to start it up the next morning, it would go through it's startup and then go to error 03. I never got it running again.I contacted the company and felt their response was subpar. A new machine that doesn't work getting a modicum of sympathy, a request to see the error codes and it seems and that is about all,I like the idea of the box, self contained diesel heater, but any new product should work out of the box...and if not, should be replaced. If hazardous materials are the hold up, then send a new heater, if with videos, it can be shown that the heater is defective. Guess that's too much to expect, it seems. Always go with a company that stands behind it's product. With these heaters, that is difficult .My fault was i didn't read the NO RETURN policy enough or at all. I thought it was something like you couldn't send it back to Amazon... It's literally, noo one accept returns by Amazon or the manufacturer. And you are stuck with a heater you have to fix, even though it is new.When I contacted the company, they thanked me for the purchase, and......"We are sorry for the inconvenience. However, for the E03 and E05, maybe you can check if the main board has something wrong."That was the solution in essence.... Become a diesel heater mechanic... So, I ordered a glow plug, took the heater apart and will work on it till I get it running. Maybe if that doesn't work I can buy a "main board" or whatever it needs.You don't always get what you pay for, as this was not one of the cheaper diesel heaters.Hope it just a bad glowplug and an easy fix. Again, like the unit, works great (for a few minutes) and really puts out the heat.

works well every climate its been used. high elevations mostly. Its for my mobile ski cabin. the remote makes it easy because it can heat up multiple vehicles with a duct splitter. heats up fast and goes all night. it ticks and sounds just like every other diesel heater. as far as heat goes, this seems to be the most effective, both cost and function. will be buying another one for my cargo trailer.
