reliability and longevity, Rinnai’ s unique condensing design incorporates two innovative heat exchangers to achieve optimum water-heating value from every cubic foot of natural gas or propane. The down-fired ceramic burner allows condensation to drain from the bottom of the heat exchanger, protecting the primary heat exchanger and burner, as well as maintaining top product performance over time. The unique condensing design maximizes heating value and earns an Energy Factor rating of up to 0.95, which translates to significant energy savings when compared to traditional gas tank water heaters.
