The ENERGY STAR rated NRC83, Noritz's ecoTOUGH Series of gas fired residential condensing tankless water heaters, is designed for smaller homes and multi-family dwellings. It is available in both indoor (the two-pipe, direct vent NRC83-DV) and outdoor (NRC83-OD) models, the new wall mounted units have an energy factor (EF) of 0.92 for natural gas and 0.94 with liquid propane - approximately 30 points higher than a standard, strage tank-type, gas-fired water heater.
Precision Combustion Control - More precise burner control, especially during low-fire demand. New intelligent freeze protection software - Improved freeze protection from extreme cold weather. No internal neutralizer - Removed from the unit to help prevent failures from a frozen neutralizer.
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
