“I’m on my third heater for my pool house. Every year I drain the system and winterize the unit and every spring the unit is full of leaks when opening the water again. (Unit installed each time by licensed plumber and winterized by the same) This is my last try. BTW, I’ve tried contacting the manufacturer numerous times with the typical run around. A shame.”

I am not sure I understand what you are saying, but the unit's have a 12 year warranty on the heating element and 5 year warranty on other parts. We have sold thousands of Rheem tankless water heaters over the year, and have not heard of this issue before. All of our customers are automatically sent the review request 11 weeks after their purchase, so if people were having issues they would definitely let us know. That said the products have a 4.8 out of 5 overall start rating, because they are great units and people love them. Also, the units are tankless, so there is nothing inside the unit holding water when it is not in use, so I am not sure what you mean by full of leaks? Lastly, there should be no problem getting a hold of Rheem. They are the largest manufacture of heating and cooling systems in the US. Their phone number will be in the owner's manual and on sticker that comes with the unit, it is 1-800-432-8373. If unit does fail it gets replaced. All said, it sounds like the unit you purchased from us in 2020 is not giving you issues. It are past units you have had problems with. Hopefully you have a better experience with this one, and I am sorry for any issues you have had in the past.

“Second best investment outside of "solar" for our home Our first Rheem lasted approximately 9 years and that was with a house of 5. When it finally died, we replaced with a slightly larger unit Very pleased”
