Rinnai CHS HCX Horizontal Hybrid System, 398,000 BTU, 119 Gal, Natural Gas

A horizontal Rinnai CHS HCX hybrid water system with a standard 119-gallon tank fed by 398,000 BTU of condensing tankless input. It is built for commercial kitchens, hotels and other natural gas sites that see heavy hot water demand at peak hours.

The tank stores water that the tankless engines have already heated, so it avoids the thermal stress of a direct-fired vessel and gives a longer service life. Faulty parts can be replaced individually. The DuoSmart digital controller manages temperature accuracy and recirculation without an aquastat, and Wi-Fi capability is included.

A factory-installed gas dirt leg, electrical access point and preassembled condensate drain shorten installation, while the gas swivel flex line rotates 360 degrees to meet the supply. The CU199 engines are 97% thermally efficient, Ultra Low NOx compliant and ENERGY STAR certified, and the package can be up to 37% lighter than a high-efficiency tank.
