Product Description
The RINNAI RX160I is a condensing tankless water heater designed for high-demand residential and light commercial hot water applications. Operating at 160,000 BTU/h input and achieving a Uniform Energy Factor (UEF) of 0.95, this unit delivers strong thermal efficiency with on-demand hot water output. The condensing design recovers heat from exhaust gases to maximize fuel utilization. Licensed plumbers and mechanical contractors are the primary trade installing this equipment in new construction and retrofit projects.
The RX160I is suited for indoor installation in residential or light commercial settings where high hot water demand requires a high-capacity tankless solution. Typical applications include large households, multi-bathroom residences, and small commercial facilities where simultaneous fixture loads require substantial continuous flow capacity. The unit is intended for natural gas service based on the RX160 product line designation.
