Noritz NCC1991-OD-NG NCC199-OD-NG
- Recaptures the heat from the exhaust and uses it to preheat incoming water before passing it through the main Copper heat exchanger.
- Efficient use of waste heat to preheat incoming water also cools the exhaust gasses, allowing this unit to be used with PVC venting material.
- Designed to provide endless hot water for residential or commercial applications.
- Direct vent (DV) models draw air from the outdoors so they DO not use any air from the indoor installation location, making them ideal for tight spaces or where indoor air is unsuitable for combustion.
- Self-Diagnostic onboard computer system, combined with the included digital remote, provides ease of maintenance and temperature adjustment.
