Rinnai RX160iN
The Rinnai RX160iN is a SENSEI RX condensing tankless water heater — a DHW-only appliance, not a boiler — firing 15,000 to 160,000 BTU/h at 0.97 UEF with up to 9 GPM maximum flow.

Rinnai RX160iN in practice
The RX160iN is a condensing tankless water heater in Rinnai's SENSEI RX line. Its official product page prints a 15,000 BTU minimum and a 160,000 BTU maximum input, a 0.97 Uniform Energy Factor and a maximum domestic hot water flow rate of 9 GPM. It heats water on demand and has no hydronic heating circuit, so it is recorded here as a DHW-only appliance.
The unit measures 18.5 W x 30.11 H x 11.4 D in and weighs 54 lb, with 3/4 in hot and cold water connections, a 3/4 in gas connection and a 1/2" NPT condensate drain (a condensing appliance produces acidic condensate that must be managed per the installation manual). It is recirculation-capable, Wi-Fi capable, ENERGY STAR rated and SCAQMD Ultra Low NOx approved, and it installs indoors or outdoors on natural gas or liquid propane.
Rinnai's pages state the SENSEI RX models use Adaptive Gas Valve Technology that adjusts to natural gas or liquid propane with no conversion kit required. For a home that also needs space heating, Rinnai's boiler lines (I-SERIES+ and the legacy i-, M- and Q-Series) handle that load; the RX160iN covers domestic hot water only and is sized on peak demand, not on a building heat-loss calculation.
Best suited to
- Domestic hot water at up to 160,000 BTU/h input
- 0.97 UEF condensing operation with 9 GPM maximum flow
- Indoor or outdoor installation with NG or LP and no conversion kit
