Rinnai RU98EN Exterior 9.8 GPM Natural Gas Tankless Water Heater

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.

The Efficiency of Condensing Technology

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 .93, Rinnai’s tankless condensing units are ideal for residential and commercial applications and can be banked for even greater capacity.
