Review: Good purchase - I purposely held off on writing this review until I had used it for a while. I live full time in my RV and my only issue was never being able to take a real shower. I purchased this water heater approximately a year ago, I was a little hesitant when installing it because I've not had much experience dealing with propane accessories but all in all it was fairly simple. For a year now, as long as there is propane in the tank I can take as long and as hot of a shower as I want. Why tankless water heaters aren't a standard item in every home is beyond comprehension.
Review: Died in 4 months - I purchased this Septer 22, 2025 and it has worked fine until yesterday, Jan. 19, 2026. It turned on with an Error Code EE then Ec then it all came on with a 888 temp and DIED. Can't be returned and No Survive left.
