Noritz NC199DVCNG Commercial Tankless Water Heater, Concentric Vent, Natural Gas

The Noritz NC199DVCNG is a commercial natural gas tankless water heater with a concentric vent, rated at 199,900 BTU and up to 9.8 GPM. It suits indoor installations in mid-sized homes and commercial spaces where two or three fixtures run at once.

Turbo Flow Technology holds 9.8 GPM at a 35°F temperature rise, which helps in colder climates. A Noritz dual flame burner limits temperature swings, an automatic air regulator keeps combustion efficient, and direct ignition removes the need for a standing pilot. Two identical units can be joined with Quick Connect to double output.

A safety lockout and a thermal fuse guard against overheating, a resin-coated circuit board shields the electronics, and freeze protection works indoors down to -30°F. The steel casing carries an acrylic coating against rust, and the wall-hung cabinet saves floor space.
