The Noritz NRC98-DV is a condensing, natural-gas tankless water heater rated at 180,000 BTU, with an Energy Factor of 0.91 and an adjustable 100–140°F range. It is a direct-vent indoor unit, so it pulls combustion air from outside and needs a sealed vent run, which sets it apart from non-condensing heaters that vent through cheaper metal pipe. Owners like the steady hot water and the service reminder and condensate overflow monitoring; installers note that condensing units need a drain for condensate and a proper vent kit. It suits households replacing a tank or upgrading to condensing efficiency, but it is a pro-install item, not a DIY swap.
