Fountain Valley, Calif.-based Noritz expanded its ecoTough Series of gas-fired residential condensing tankless water heaters with the new NRC83.

The Energy Star-rated unit is designed for smaller homes and multi-family dwellings. 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, storage tank-type, gas-fired water heater.
