The Rinnai Demand Duo 2 hybrid water-heating system has two commercial CU199 tankless water heaters connected to a 119-gallon tank. No need to purchase multiple tank water heaters; the Demand Duo 2 features built-in redundancy and storage for high spike draws. Equipped with DuoSmart Tank Technology, the preinstalled recovery pump, controller, isolation valves and electrical junction box work together to maintain consistent temperature, and lower acquisition, operating and life cycle costs.
