Description

The Rinnai Demand Duo® H-Series Indoor Commercial Hybrid Unit is engineered to redefine commercial water heating efficiency. With a 119-gallon tank capacity and an impressive 315-gallon first-hour delivery, this system delivers hot water on demand — even during peak usage periods.

Designed with advanced hybrid technology, it blends the reliability of storage with the energy efficiency of tankless systems. The 97% thermal efficiency ensures substantial energy savings, while the 199,000 BTU capacity provides rapid recovery for demanding commercial environments.

Installation is fast and flexible thanks to pre-assembled gas and electrical connections. Its integrated pump control optimizes recovery logic for consistent water temperatures, and multiple venting options (PVC, CPVC, Polypropylene, or common vent) reduce labor and installation costs.

Built for restaurants, hotels, schools, and industrial facilities, the Rinnai H-Series offers durability, cost savings, and reliable performance—a true upgrade from traditional water heaters.

Key Features:

  • Hybrid Power Efficiency – Combines tank and tankless technology for optimal hot water delivery.
  • Exceptional Recovery Rate – Delivers up to 315 gallons in the first hour.
  • 97% Thermal Efficiency – Saves significantly on operating and energy costs.
  • Integrated Pump Control – Optimized recovery logic ensures consistent hot water supply.
  • Pre-Assembled Connections – Simplifies installation with ready-to-connect gas and electrical fittings.
  • Dual Thermistors – Provides precise temperature control for consistent output.
  • Flexible Venting Options – Supports PVC/CPVC, Concentric Polypropylene, and common vent configurations.
