I only used this once to test it out before install. So far it works nice. Puts out a decent amount of dry heat.Will be installing this In my shower house at camp this fall. Once installed and used a few times I will update my review.A few things to note as of now.- the instructions manual isn_ the greatest. Needs reading a few times to try understand the translation- need to cycle the unit a few times to start getting diesel to the heat exchanger. I noticed a huge air bubble in the supply line from the pump to the exchanger. I will correct this issue during installation. That being said even with the air lock it ran great on drops of diesel. I would suggest priming the fuel line before initial start up.- I personally don_ like that the fuel line rubs on the mount bracket for the fuel tank to sit on. The fuel line runs through a hole. Can be easily corrected by installing small spiral wrap or if someone would want to use heat shrink. Minor issue. I_ nit picky for things like that.
