Product Description
The RINNAI CX199I is a condensing tankless water heater rated at 199,000 BTU/h with a 97 percent thermal efficiency rating. It operates on a continuous on-demand flow model, heating water only when there is demand rather than maintaining a stored tank. The high thermal efficiency rating places it in the condensing category, meaning it recovers latent heat from exhaust gases to maximize fuel utilization. This unit is designed for indoor installation and is typically specified and installed by licensed plumbers or mechanical contractors on residential or light commercial projects requiring high-output hot water supply.
The CX199I is suited for applications where simultaneous hot water demand is high, such as multi-bathroom residential homes, small commercial facilities, or installations requiring a high-capacity single unit. Its 199,000 BTU/h input allows it to serve multiple fixtures concurrently when properly sized and installed. Indoor mounting configurations make it appropriate for utility rooms, mechanical closets, and dedicated equipment spaces with proper venting provisions.
Key Features
- 199,000 BTU/h input capacity supports high simultaneous hot water demand
