Noritz's most efficient commercial tankless heaters, the next generation in tankless technology - condensing heaters. NCC1991 is the new LowNOx version of NCC199. 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.
About our Commerical Models
With its stainless steel exterior casing and commercial grade components, the Noritz 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.
