    The instructions on how to adjust the settings and what each control is for,is lacking. some additional helpful tips,on adjusting would be helpful. Once, I got it dialed in it works great. I replaced my regular rv water heater wirh this and now I never run out of hot,water. customer service is amazing!

  • Great unit!

    Installed this in my 5th wheel. Plumbed up and vented out the roof. This unit can heat water no joke. More hot water than I need, but its nice to have the option, especially when your incoming water supply is cold. I have the unit settings set fairly low and I mix at the shower fixture or sink fixtures to preference. I like that it has a switch to cut power also. Only thing sucks is the bsp type connections and here in USA were npt. Comes with hose connection adaptors but not what I need in my case. No biggie, I used plastic elbows that were previously from the old rv water heater with some Teflon paste. I have a carbon monoxide alarm as well.
