Super Efficient – DOE Energy Factor of 0.92 (Natural Gas)/0.94 (Propane) 12 year warranty – Longer coverage than competition, 12 years on heat exchanger, 5 years on parts, 1 year labor Installation flexibility – PVC or CPVC piping. The less costly, zero clearance plastic piping enables longer vent runs up to 62 linear feet. Built-in PVC adapter for either 3″ or 4″ PVC or CPVC. Stable Temperature Control – No need for a buffer tank to stabilize temperature. Therefore, no stand by heat loss Low Pressure Loss – Norirtz provides a better shower experience across a wide range of water pressures.
Temperature Display – Can be changed from F to C Service Reminder – Can be set to remind user to flush heat exchanger or change H2Flow cartridge Vent Length and High Elevation Adjustments – Use dipswitches on circuit board
