These low cost little diesel heaters from china are actually kinda cool, they are lot cheaper than the american made ones, and actually work pretty good surprisingly. It took me about an hour to set it up and get it working. The main issue is, the heat exhaust and combustion air intake come out the bottom, so you have to mount it up in the air about 8 to 10 inches, so you can get the hot exhaust flexible pipe routed outside. I just used some scrap pieces of 2x4 lumber and made a little stand to screw it to....no biggie. I was surprised at the massive amount of heat coming out of this heater, and it doesn't use much fuel. I ran mine the first day for 14 hours continuously on less than 1 gallon. You can save considerable money if you purchase ruby red diesel fuel which doesn't have road tax. You cant buy it just anywhere tho, usually have to go to a farm type store or farmers fueling station. In central Kansas it is about $2.69 a gallon. You can also use kerosene as well, which puts out even more heat, but it is over $4 a gallon. Great Job VEVOR! Cheers
