931

For our luxury line, we have the 931 series which can provide endless hot water for up to 4+ showers.  And with its Quick-Connect system, two units can be linked together to meet the high demand of today’s luxury homes.  To accommodate the higher flow rate demand, these units have a dual flame burner, a redesigned heat exchanger and 25% thicker copper piping.  No other tankless water heater in its class can beat its performance, dependability, and quality.  Built-in features include safety lock-out, freeze protection, and high elevation adjustment. 

These units offer several innovations: 

·         Safety lock out - Default max. 120 degrees (refer to owner's manual for higher temp)

·         Dual flame burner - Noritz exclusive!  Minimizes temperature fluctuations.

·         Fully modulating - Automatically adjusts burner level accordingly.

·         Turbo Flow - Up to 11.1 GPM @ 35 degree temperature rise (9.3 GPM @ 45 degree rise).

·         Quick Connect - Doubles the output by connecting two identical heaters.

·         Direct ignition - No standby pilot light.

·         Thermal fuse - Automatic overheat protection system.

·         Resin coated PC board - Increases durability and protection from elements.

·         Automatic air regulator - Monitors internal temperature/maximizes burner efficiency.

·         Fully modulating - Automatically adjusts burner level accordingly.
