High Efficiency Condensing Combi-Boiler, AFUE 95%, Space Heating Up to 150,000 BTU/H, Domestic Hot Water Up to 210,000 BTU/H
Dual stainless steel heat exchanger: 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:Â 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:Â 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.
