Set this up in my work trailer to keep me warm and my cordless tool battery's happy. The thing works great.
Like any of these heaters... The fuel pump is noisy. And when i set the comtroller to a temp that i expect it to shut down at .. well.. it never shuts down. So i may be miasing something. But the intructions could be a bit more detailed as expected. All in all im happy with it thus far and think i could safely recommend it to others. And im a picky ba***** (but then again there is a lot of bang for the buck here so im probably not being overly critical).
Buy it. Use it.
If your not mechanically inclined, pay someone who is to install it.
