With its stainless steel exterior casing and commercial grade components, the Noritz ASME certified tankless hot water heaters are specifically designed to meet the demands of commercial applications. For heavy-duty industrial use, up to 24 ASME certified tankless models can be linked together with a single system controller, supplying a maximum of 316.8 GPM at 9.1 million BTUs (with NC380-SV-ASME model). The copper piping in the unit’s heat exchanger is 25% thicker, providing extra durability to help prevent condensation and combat product failure.
The NC380-SV-ASME is one of the largest capacity tankless water heater on the market today. Features include Quick-Connect and Multi-System capability and is best suited for heavy commercial use. Obviously since the unit is built larger the tubing diameter is larger also, which results in faster hot water delivery than our competition (don’t get fooled by imitators that put two smaller units into one huge heater case!). The Multi-System configuration, used with a single system controller, allows multiple units (up to 24) to be linked together for large demand applications. ASME certified tankless water heaters have a non-prorated 5yr warranty.*
The ASME certified NC250-SV-ASME, our standard single flue vented model, allows the unit to be installed indoors or outdoors and vented horizontally or vertically. In addition, the NC250-SV is Quick-Connect and Multi-System compatible. The Multi-System configuration, used with a single system controller, allows up to 24 units to be linked together for large commercial hot water applications. ASME certified tankless water heaters have a non-prorated 5yr warranty.*
The ASME certified NC250-DV, our Direct Vent (sealed combustion) double flue vented model, is best suited for commercial businesses that have tight indoor space or contaminants in the air, such as hairspray in salons and grease in restaurant kitchens. In addition, the NC250-DV is Quick-Connect and Multi-System compatible. The Multi-System configuration, used with a single system controller, allows multiple units (up to 24) to be linked together for large demand applications. ASME certified tankless water heaters have a non-prorated 5yr warranty.**
Noritz is proud to introduce our tankless condensing heaters, the next generation in tankless technology. This innovation utilizes a dual heat exchanger - a fusion of stainless steel and copper heat exchangers. The 100% stainless steel component captures the residual heat from the exhaust temperature to preheat the incoming water before it runs through the main copper heat exchanger. This results in dramatic reduction of carbon dioxide and increases the heater’s efficiency level to over 93%! Another benefit of this technology is lower exhaust temperatures, which means less costly PVC can be used for its venting.
The NH series provides quiet and constant room temperature comfort in the home for various house heating choices, such as panel radiators, baseboard flooring and radiant flooring. The most important benefit of hydronic heating is allergens or dust will not be re-circulated in the home, which happens when using forced air furnaces. Noritz tankless hydronic boilers warm objects in a room, providing a higher level of warmth and comfort.
Features include: State-of-the-Art Heating Controls, Dual Temperature Controls, Fully Modulating Controls, and Self-Diagnostic System
QUICK-CONNECT and MULTI-SYSTEM
The NC250 and NC380 series have the capability of connecting two units together with a Quick-Connect cord. When connected together by this cord, the two units can be controlled by a single digital remote thermostat which doubles hot water capacity. The Multi-System configuration, used with a single system controller, allows up to 24 units to be linked together for large demand applications.
The copper heat exchanger is coated to prevent corrosion and deterioration, increasing the life of the product.
The models have internal piping that is 25% thicker than the competition, to help prevent condensation and combat water heater failure.
Our burners use the latest in gas combustion technology, a result from over 50 years of developing and fine tuning tankless technology. This advanced water heater technology maximizes the output while maintaining high efficiency, which also results in lower CO2 emissions.
Noritzâ€™s revolutionary PC board is at the heart of its tankless technology. The Electronic Burner controls use cutting-edge technology to provide endless hot water at a constant temperature. The controls are lacquer coated to help prevent any deterioration of circuit elements and an on-board memory chip stores an error code history for easy maintenance monitoring.
*Noritz offers a non-prorated 5-year Commercial Warranty on the heat exchanger and parts for all of its ASME tankless water heaters only (does not include the NH series and NCC199 series).
NOTE: Noritz America does not offer fuel oil or electric tankless water heaters.
