The Rinnai SENSEI® RX160iN High-Efficiency Condensing Tankless Water Heater is designed to provide continuous, on-demand hot water in a compact wall-mounted system. With up to 160,000 BTU/h of heating input and a maximum rated flow of 9.0 GPM, it offers dependable performance for professionally sized residential hot-water applications.
Unlike a conventional storage-tank water heater, the RX160iN heats water only when a fixture is being used. Its modulating operation adjusts heating output according to demand, helping reduce standby energy loss while maintaining consistent water temperatures.
With a 0.97 Uniform Energy Factor and ENERGY STAR® certification, the RX160iN delivers super-high-efficiency condensing performance. Its condensing system captures additional heat from combustion exhaust before it leaves the unit, supporting efficient operation without sacrificing everyday hot-water comfort.
Rinnai’s Smart Sense™ Adaptive Gas Valve Technology allows the same water heater to operate with natural gas or propane without requiring a separate field-conversion kit. Gas configuration and commissioning must be completed by a qualified professional according to Rinnai instructions.
Approximately the size of a small suitcase, the RX160iN measures 18.5 inches wide, 30.11 inches high and 11.4 inches deep. Its wall-mounted design helps preserve valuable floor space and provides flexible placement in utility rooms, basements and suitable mechanical areas.
The unit supports indoor installation or outdoor mounting with the optional Rinnai Versa-Vent™ outdoor vent-cap accessory. This installation flexibility allows one model to accommodate a wider range of replacement and new-construction applications.
The RX160iN is also recirculation capable and Wi-Fi capable when configured with compatible Rinnai components and accessories. Smart Connect™ Bluetooth technology helps qualified installers simplify setup and registration using the Rinnai Central™ app, while Quick Flush™ technology helps streamline periodic maintenance.

Not the cheapest option, but the installation quality and product reliability feel solid.

The Rinnai RX160 performs well, but the initial setup required a bit of adjustmen
Ayesha Khan –
Jimmy HVAC staff were easy to deal with and answered questions without rushing.
Paul Moreau –
Everything works as described. Still monitoring energy usage but so far it seems efficient
Minh Tran –
Unit runs quietly and takes up much less space than our old tank heater.
Nicole Davidson –
Installers were professional but the job took a bit longer than expected. End result looks clean.
Jason Lambert –
Service was fast. Booked on Monday and installation was done by Thursday.
Farah Ali –
Switched from a tank to the Rinnai RX160. It handles multiple showers without running out.
Kevin O’Brien –
Pricing was reasonable compared to other HVAC companies we contacted. No hidden costs.
Harpreet Singh –
Overall happy with the unit, though there’s a short delay before hot water reaches the far bathroom.
Mélanie Roy –
Installation team showed up on time and finished the job the same day. Everything was explained clearly.
Steven Caldwell –
The Rinnai RX160 has been working fine so far. Hot water is consistent.
dhani –
This size is perfect for a family home — it easily handles two to three bathrooms without any drop in performance. If you have a larger household, you might want a higher BTU model, but for us, this has been an excellent choice.
Jimmy Mehra –
Installation needed a professional, especially for the gas line and venting, but once it was set up, everything worked flawlessly. Energy use has noticeably dropped, and I appreciate that it only heats water
Jimmy Mehra –
Installation needed a professional, especially for the gas line and venting, but once it was set up, everything worked flawlessly. Energy use has noticeably dropped, and I appreciate that it only heats water when needed instead of constantly keeping a tank hot.
jose patel –
recently upgraded to a 160,000 BTU tankless water heater, and the difference is night and day compared to my old tank system. Hot water is available instantly, and I never have to worry about running out, even with multiple showers running. The unit is compact, quiet, and much more efficient than my previous heater.
