Noritz NORNC199OD-NG 199000 Btu/h Outdoor Gas Tankless Heater

Product Description

The NORITZ NORNC199OD-NG is a commercial-grade outdoor natural gas tankless water heater rated at 199,000 BTU/h. Designed for on-demand hot water delivery with no storage tank, it heats water only when there is demand, eliminating standby heat loss. The unit is built for outdoor installation, making it suitable for applications where indoor venting infrastructure is limited or unavailable. Ultra Low NOx combustion technology reduces nitrogen oxide emissions to meet strict air quality regulations in applicable regions. Licensed plumbers and mechanical contractors are the primary installers for this class of equipment.

This tankless water heater is suited for commercial applications requiring high-capacity continuous hot water output. Typical installations include restaurants, small lodging facilities, multi-unit residential buildings, and light commercial properties where demand exceeds residential-grade equipment capacity. The outdoor-rated enclosure eliminates the need for dedicated venting runs through a structure, simplifying installation in retrofit and new-construction scenarios alike.
