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.
