The Rinnai Demand Duo H-Series (CHS199100HCXIN) is a commercial hybrid water heating system that provides continuous, high-volume hot water. By combining a 119-gallon storage tank with a high-efficiency condensing tankless unit, it provides first-hour delivery, stable temperatures under peak load, and improved energy efficiency. With a total input capacity up to 199,000 BTU and advanced hybrid controls, the CHS system is designed to reduce recovery lag, minimize downtime, and maintain consistent output.
Key Features
Dual High-Efficiency Tankless System with Condensing Performance
Integrates two SENSEI CX199i condensing tankless water heaters into a pre-assembled rack system, delivering high-capacity commercial hot water output with up to ~10.8 GPM at a 70°F rise.
Built-In Cascade Control for Load Balancing & Redundancy
Intelligent system controls automatically stage and balance operation between both units, improving efficiency under partial loads while providing built-in redundancy to maintain hot water supply during service or maintenance.
Space-Saving Wall-Mounted Commercial Design
Low-profile aluminum rack construction allows for wall mounting, freeing valuable mechanical room floor space and simplifying installation in tight retrofit or equipment replacement scenarios.
Simplified Commercial Installation & Utility Connections
