Description
Navien NCB-H Series130 MBH Condensing Combi 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 holds a steady shower temperature at low draw instead of swinging hot and cold, and keeps the burner running at part load through most of the heating season.
