Available in four models, suitable for mid- to large-sized homes, Rinnai’s new Ultra Series Condensing Tankless Water Heaters offer all the same benefits builders and homeowners have come to expect from Rinnai. Never run out of hot water again, and enjoy the space savings, convenience, ease of installation and peace of mind for which Rinnai is famous. Rinnai’s unique condensing design incorporates two innovative heat exchangers to achieve optimum heating value from every cubic foot of natural gas or propane. The stainless steel system recaptures residual heat from flue gases to pre-heat incoming ground water, which then circulates to the primary copper heat exchanger. Delivering an Energy Factor (EF) up to .96, Rinnai’s tankless condensing units are ideal for residential and commercial applications and can be banked for even greater capacity RU Series interior-mount units can be placed in any room, vent directly to the outside and have an integrated condensate collector. All RU units contain a newly designed, commercial-grade dual heat exchanger for optimum durability.
