Rinnai’s Ultra Series RUR models do not require a dedicated return line or a complex, expensive building of system components by the contractor. The models can be installed using crossover technology, which utilizes a thermal bypass valve supplied in the box. Through this thermal bypass valve, along with the integrated pump and internal bypass line, the models deliver hot water faster. The premium MC-195T digital controller, included as a standard feature, allows the user to save on gas utility bills by scheduling multiple recirculation events throughout the day to align with usage patterns.
