Overview
The Navien NCB-H Series condensing combi gas boiler puts 130 MBH of heating capacity and up to 10.4 GPM of domestic hot water into one wall-hung cabinet, with a 15:1 turndown ratio on the DHW side. That wide modulation range is what lets it hold a steady shower temperature at low draw instead of swinging hot and cold, and it keeps the burner running at part load through most of the heating season at 95% AFUE. A stainless steel heat exchanger handles the acidic condensate that comes with condensing operation, and direct-vent sealed combustion allows PVC or polypropylene venting through a sidewall, so no chimney is needed. Runs on natural gas or propane, mounts on the wall in a 12-4/5 in. deep cabinet, and operates on standard 120V power. ENERGY STAR qualified. Installation by a licensed gas heating contractor is required.
