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. Please note that this unit must be mounted indoors and has a twin pipe direct vent configuration.
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 sourthern homes with three baths.
ATTENTION!!! 3" or 4" PVC venting can only be used on condensing heaters (PVC adapter is built-in).
Noritz prides itself on being the best tankless water heater manufacturer to supply all of your commercial hot water needs. To determine which tankless water heater model is right for you, you first need to identify your peak hot water usage. The estimation chart shown can guide you to find the right sized commercial tankless hot water heater for your commercial building. Please note that this unit must be mounted indoors and has a twin pipe direct vent configuration.
Each showerhead illustrated above is about 2 GPM, which is roughly what a standard showerhead, bathroom sink, dishwasher, and washing machine would use. To meet all commercial hot water heater needs, these tankless hot water heaters can be linked together to provide on-demand hot water for every application. The number of showerheads next to each series shows the heater’s capacity of providing hot water simultaneously.
PLEASE NOTE: The chart is for ESTIMATION ONLY. Before installation, have a registered plumber size the application according to Noritz Specification Sheets to ensure the model can accommodate your hot water needs.
