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.

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.

Used this heater to heat a 16' enclosed camp trailer. Very nice small enclosure, capable of operating outside the trailer, with a duct piping the hot air in. Ran it on highest setting during snowy nights, ran all night and kept the trailer warm. Used about half of the 6L fuel tank to heat for the entire evening.The wireless remote works well also. We were able to operate the heater from inside the trailer.....felt a little fancy!

I never write reviews, but I felt my Hcalory deserved a few words. I did my research on this item through reviews and watching videos on Youtube. I basically, reviewed just about every make and model of diesel heater and landed on this one. All of these Chinese built heaters are basically the same heater design just configured differently as far as size and shape. I chose this unit because it had a more compact design, looked more stable, side exhaust, tool box design and had dual voltage capabilities of 12v dc/120v ac.This unit arrived in an undamaged box with no apparent damage to the unit. It seemed well built and I was impressed with the design. I read the owners manual and began the setup for the initial firing. I fueled and plugged it into 120v ac with the supplied power supply. The control display would not light up on the controller. It did however start and run, but I could not tell what mode of operation it was in or pair the unit with my phone app. It ran well and I was impressed with the amount of heat this small unit put out. The only thing that works on the control panel was the power button and fan speed although they do not light up on the display. I contacted Amazon a week ago and still have not heard from them. I also reached out to the manufacturer Hcalory in China who replied to my email within 24 hours. They were very polite and courteous. They had no record of me buying it from their website since it was ordered from Amazon. I gave them my Amazon order number and they said they would send me a new controller when they got one in stock? In stock, don't they manufacture these units? I have used it a few times and I really liked this little heater despite the control panel not working correctly.Today I tried to start it and it said there was an ignition failure (it talks to you). So apparently the glow plug is out now. I tried to restart the unit dozens of times with the same result. I tried hooking it up to 12v dc and it will not do anything at all, meaning it does not work on 12v dc either.Powering with 120v ac it at least it will try to go through the ignition cycle and tell you there is a failure. If you purchase this item you cannot send these units back since they had fuel in them. So now I have a heater with no control panel, it will not fire, it will not work on 12v dc and it will not heat When and if I receive a new controller, it may solve these issues. I ordered this heater on Dec 31st 2023, received it on Jan. 4, 2024 with the initial firing on Jan. 6th. Today is Jan. 13th. For now I just have a $200 way to store 6 liters of diesel fuel. I am not a happy camper."Updated Review"After my initial review the seller contacted me. They were very courteous and prompt with their questions and answers regarding my problems. They quickly offered a resolution to my problem which I accepted. I am happy with the results. They stand behind their products as I can attest. I must have got a unit that got bounced around a little too much during shipping. I really appreciate the customer service at LuneGus!
