Comparison
Verdict in brief
The RX130iN and RX160iN are adjacent SENSEI RX condensing tankless water heaters, both 0.97 UEF, 54 lb and sharing the same cabinet. The RX160iN raises input from 130,000 to 160,000 BTU/h and maximum flow from 7.1 to 9.0 GPM; both start at a 15,000 BTU/h minimum.

| Specification | Rinnai RX130iN | Rinnai RX160iN |
|---|---|---|
| Minimum input (hero bullet) | 15 MBH | 15 MBH |
| Maximum input (hero bullet) | 130 MBH | 160 MBH |
| Uniform Energy Factor (UEF) | 0.97 UEF | 0.97 UEF |
| Domestic hot water flow rate (maximum) | 7.1 GPM | 9 GPM |
| Product weight | 54 lb | 54 lb |
Both models are condensing tankless water heaters in Rinnai's flagship SENSEI RX line, and both are DHW-only appliances with no hydronic heating circuit. They share a 15,000 BTU/h minimum fire, 0.97 UEF, a 54 lb, 18.5 x 30.11 x 11.4 in cabinet, 3/4 in water and gas connections and a 1/2" NPT condensate drain.
The step is capacity: the RX160iN fires to 160,000 BTU/h against 130,000 and publishes 9.0 GPM maximum flow against 7.1. That extra flow supports heavier simultaneous hot-water use or colder incoming water; the identical minimum fire means both modulate down to the same floor in light demand.
Both install indoors or outdoors and run on natural gas or liquid propane via Rinnai's Adaptive Gas Valve Technology with no conversion kit, and both are recirculation-capable, Wi-Fi capable, ENERGY STAR rated and SCAQMD Ultra Low NOx approved. Sizing follows the peak hot-water demand calculation.
Rinnai
The Rinnai RX130iN is a SENSEI RX condensing tankless water heater — a DHW-only appliance, not a boiler — firing 15,000 to 130,000 BTU/h at 0.97 UEF with up to 7.1 GPM maximum flow.
Rinnai
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.
No. Both print 0.97 UEF; the difference is capacity — 130,000 against 160,000 BTU/h input and 7.1 against 9.0 GPM maximum flow.
They are condensing tankless water heaters (DHW-only). Rinnai's boiler lines are the I-SERIES+ and the legacy i-, M- and Q-Series.
Sizing depends on peak fixture demand and incoming water temperature, not floor area. The RX130iN publishes 7.1 GPM and the RX160iN 9.0 GPM; a licensed contractor should confirm the calculation.
A consultation includes a heat-loss review so the size is right the first time.
