Rinnai’s Ultra Series condensing water-heating technology combines the benefits of traditional tankless water heaters with even greater energy savings for commercial applications. For built-in reliability and longevity, Rinnai’s condensing design incorporates two innovative heat exchangers to achieve optimum water-heating value for 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 condensing design maximizes heating value and earns an Energy Factor of up to .95, which translates to significant energy savings.
