Their focus includes gas-fired units (natural gas and propane) with advanced combustion technology and precise temperature control systems.

Technologies & Innovation

Proprietary Features
Noritz features patented Multi-Point ignition system for faster startup, commercial-grade heat exchangers made from stainless steel or copper, and advanced modulation technology that adjusts gas input based on demand.

Energy Efficiency
Noritz tankless units achieve up to 96% thermal efficiency with their condensing models and up to 84% with non-condensing units. Energy Factor (EF) ratings range from 0.82 to 0.96, and many models are ENERGY STAR certified, providing significant energy savings compared to traditional tank water heaters.
Smart Controls
Noritz offers WiFi-enabled models with smartphone app control through their Noritz Connect system. Features include remote temperature adjustment, usage monitoring, maintenance alerts, and diagnostic capabilities. Advanced digital displays provide real-time status updates and error codes.
Certifications
All Noritz units are certified by major North American standards organizations including CSA, ANSI, and ASME. Many models carry ENERGY STAR certification and meet strict California Air Resources Board (CARB) and South Coast Air Quality Management District (SCAQMD) emissions standards.

Best Use Cases
