Unrivaled Technology. Unmatched Performance.
Rinnai’s unique condensing design incorporates two innovative heat exchangers to achieve optimum heating value from every cubic foot of natural gas or propane. Residual heat from flue gases is recaptured to pre-heat incoming ground water, which then circulates to the primary copper heat exchanger. The top-down burner design increases reliability and ensures a longer service life, while also reducing lifetime operating and maintenance costs. With the burner located above the condensing heat exchanger, the burner and copper heat exchanger are protected from condensate. Delivering an Energy Factor (EF) up to .96, Rinnai’s tankless condensing units are ideal for residential and commercial applications and can be banked together for even greater capacity.
