Navien has started shipping its new lines of fire tube boilers and combi-boilers. The NFB-H condensing fire tube boilers and NFC-H condensing fire tube combi-boilers were first introduced by Navien during the Boiler Virtual Launch Event on February 16.

New high-efficiency features on the NFB-H include turndown ratios up to 15:1, powered connections for 3 zone pumps or 3 zone reduce areas valves, easy to use Setup Wizard for improved installation, 2" venting up to 65' and 3" venting up to 150'.
