Rinnai America Corporation

Ultra Series Condensing Water-Heating Technology

Rinnai incorporates two heat exchangers with their Ultra Series Condensing Water-Heating Technology to achieve maximum heating value while earning an Energy Factor rating of up to 0.96. The down-fired ceramic burner allows condensation to drain from the bottom of the heat exchanger, protecting the primary heat exchanger and burner. Each unit comes standard with circ-logic technology and timer controller, which allows for recirculation patterns to be set to coincide with household usage patterns.
