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.
>> ATTENTION!!! 3″ or 4″ PVC venting can only be used on condensing heaters.

Maury from Cozy Comfort did a fantastic job of examining the functionality of my furnace and cleaning the major components. He tested my furnace to make sure that it would run efficiently in the winter. My humidifier was cleaned, the drip pad replaced and settings properly set up. Thank you Maury for your effective care. thank you Cozy Comfort- you are a company that has proven your worth over the past 25 years that you have looked after my family's heating and cooling needs.

The team installed the new heater quickly and ensured the location was clean afterwards. Overall, I was very satisfied with the installation and service.
