For our luxury line, we have the 931 series which can provide endless hot water up to 4+ showers at a time.  And with its Quick-Connect system, two units can be linked together to meet the high demand of today’s luxury homes.  To accomodate the higher flow rate demand, these units have a dual flame burner, redesigned heat exchanger and 25% thicker copper piping.  No other tankless water heater in its class can beat its performance, dependability, and quality.  The N-0931M is for indoor/outdoor use.  The N-0931M-DV is for indoor use only.  The N-0931M-OD is for outdoor use only.
