Our innovative EcoTOUGH NRC661 is one of the highest quality tankless water heaters. The efficient technology in the tankless system reduces the amount of water you use. This, in turn, is not only good for the environment but also for your wallet. Built with precision quality, the NRC661 can last up to 15 years; almost double what a typical tank type heater lasts.
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, storage tank-type, gas-fired water heater.
The ENERGY STAR rated NRC98, Noritz's brand new ultra-high efficient condensing model, demonstrates its ongoing commitment to the green movement by expanding its newest tankless water heater product line: the ecoTOUGH Series of high efficiency, easy-to-install, gas-fired condensing tankless water heaters.
Offering a maximum input of 180,000 BTU per hour, the NRC98 Tankless Water Heater is designed to fully meet the domestic hot water needs of northern residences with two bathrooms and southern homes with three baths.
Noritz is proud to introduce our most efficient tankless heaters, the next generation in tankless technology - condensing heaters. This innovation utilizes a dual heat exchanger, a fusion of stainless steel and copper heat exchangers. The 100% stainless steel component captures the residual heat from the exhaust temperature to preheat the incoming water before it runs through the main copper heat exchanger. This results in a dramatic reduction of carbon dioxide and increases the heater's efficiency level to over 93%! Another benefit of this technology is lower exhaust temperatures, which means less costly PVC can be used for its venting. A PVC adapter is built into the heater for easy installation.
