Product Details

Rinnai 398K BTU 68" Natural Gas H-Series Hybrid Water Heating System ASME Ultra Low NOx CHS398100HCXAiN

The Rinnai Demand Duo™ H-Series ASME (CHS-HCX2A Model Series) is a high-performance commercial hybrid water heating system engineered for facilities requiring ASME-certified pressure vessels. This 398,000 BTU Natural Gas system combines a 119-gallon ASME-certified storage tank with dual high-efficiency tankless engines to deliver superior performance, redundancy, and energy savings.

Designed for demanding commercial applications such as hospitals, multifamily buildings, hotels, and large facilities, this system provides built-in redundancy to help eliminate “no hot water” events while achieving an ultra-high 0.98 Uniform Energy Factor (UEF). Its hybrid design reduces thermal stress on the tank, significantly extending service life compared to traditional high-efficiency commercial storage tanks.

Important Note:
Installation, commissioning, and servicing of this heating equipment must be performed by a licensed and qualified professional in strict compliance with manufacturer guidelines, local codes, and industry standards. The manufacturer does not accept warranty claims or technical support inquiries from homeowners or unlicensed individuals. All warranty and technical inquiries must be initiated by the licensed professional responsible for installation.

Product Features:

  • ASME Certified Tank: Engineered to meet stringent commercial building code and pressure vessel requirements.
  • Dual Engine Redundancy: Two integrated tankless engines provide consistent hot water even during peak demand.
  • Ultra-High Efficiency: 0.98 UEF significantly reduces energy consumption and operating costs.
  • Ultra Low NOx: Meets strict emissions requirements for environmentally sensitive regions.
  • Extended Service Life: Hybrid design minimizes thermal stress, increasing durability and reliability.
