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.
