Product Overview

The ENERGY STAR rated NRC98OD is one of many Noritz efficient condensing models. We continue to demonstrate our ongoing commitment to the green movement by expanding our newest tankless water heater product line: the ecoTOUGH Series of high efficiency. This water heater is a high efficiency, fully condensing appliance. Unlike a traditional tankless water heater, a condensing model captures heat from the exhaust gas and uses it to preheat the incoming cold water as it passes through the secondary heat exchanger.
