Rinnai RSC160iP Smart-Circ Condensing Gas Tankless Water Heater, Super High Efficiency Plus Propane Heater, Up to 9 GPM, Indoor Installation, 160,000 BTU

The Rinnai RSC160iP Smart-Circ Condensing Gas Tankless Water Heater has received mixed reviews from users. While some customers were satisfied with the product and its performance, others faced challenges during installation and found certain operational aspects to be less than ideal. One customer mentioned that the water line connection ports on the new model did not align with the previous models, causing installation difficulties and additional expenses, as a missing connector needed to be purchased separately. Another user had to re-route the plumbing in the closet to accommodate the bottom connections on the tankless unit, even though the resulting fit was cleaner. The unit includes a recirculating pump that works with the cold water line without requiring a dedicated recirculation line, which was appreciated. However, there were complaints about the recirculation system running more frequently than needed, and the fan activating almost every time cold water was turned on, resulting in a noticeable low-frequency hum during operation. Although the quick hot water from the recirculation system was praised, the frequent running of the recirculating system and fan, regardless of water usage, was highlighted as a drawback. In summary, while the Rinnai RSC160iP offers benefits such as endless hot water and a compact form, customers should be prepared for potential noise issues when mounting the unit on an interior wall.
