Product ReviewsRinnai RU199eP Tankless Water Heater - Gray (REU-N3237W-US)

Great deal on a great water heater.

The water heater had a couple minor scratches which did not affect performance. The water heater came with all the original components that I needed to complete the install. I am using the water heater as a dual purpose heater. It provides domestic hot water and it provides hot water for a centralized, multi-zone hydronic heating system also. One of the valves on the hydronic heating system was stuck open and the heating system ran continuously for a couple weeks. When I found the situation, after two solid weeks of putting out hot water for the system, the water heater was just chugging along, silently. I had to check the exhaust output and view the operation indicator to tell the unit was running. So, this is an awesome water heater and the price can't be beaten. The company ships quickly and the product arrived with no further damage than what it was advertised as having.
