Dual stainless steel heat exchangers for heating Durable stainless steel heat exchangers resist corrosion, resulting in longer life and improved heat recovery from flue gases for superior efficiency.	Up to 5.4 GPM @ 70°F temperature rise for DHW Separate stainless steel flat plate heat exchanger for DHW creates the lightest flow rates for any combi-boiler in the industry.	Dual Venturi and field gas convertibility Dual Venturi system creates better combustion control and turndown ratio. Orifice conversion kit for easy field gas convertibility from NG to LP is included with every NCB-H Series combi-boiler.
Easy access to DHW module and valves All components of DHW module including water feed valve, flow adjustment valve, mixing valve and 3-way valve are right behind circuit board for easy serviceability.	Low noise levels Installations in or near media rooms, recreation rooms or any living areas of the house are possible with the quiet running NCB-H combi-boilers.	TDR 15:1 for DHW and up to 11:1 for heating The sophisticated gas flow control system provides a high turndown ratio, reducing energy waste and excessive boiler cycling and enhances temperature control for DHW.

Dual Stainless Steel Heat Exchanger Designed for exceptional heating performance and longevity Heating up to 150,000 BTUs per hour
