Love the idea and concept. Unfortunately the one I ordered had either a bad control board or wire harness to the LCD display. Wayfair customer service was very eager to help. Unfortunately, since the part we suspected was still on back order with the manufacturer, I had to return it. Wayfair made it simple. Since they did not have another Rheem model in stock, I had to source one elsewhere to utilize the proprietary exhaust this manufacturer uses. New one works great, as I suspect this one would have had the part been available.. Ron. Albrightsville, PA. Wed Apr 30 2025

I installed this unit in my 2/1 1960's condo replacing a 30gal water heater. What a great product! The install was easy i had to upgrade my breaker to a 60 from a 30 which meant upgrading the wiring gauge, which wasn't hard at all. I have hot water on demand now that never runs out! my 30 gal tank would only provide about a 5 min shower now its as long as i want. I have to fill my tub with free flow hot water at only half flow but to keep hot water but i figured as much from such a small unit. overall it was very much worth it to ditch the hot water storage tank and have hot water on demand for as along as in need it. If i were to try to heat a larger house with 2 or 3 baths I would suggest a larger unit but the product is GREAT!!. Nonya. FL. Wed Apr 10 2024
