Pleasantly surprised by the efficiency of the Navien boiler. The energy savings are noticeable even on the first bills. Excellent choice for those who appreciate quality and economy.
Dual Venturi system creates better combustion control, turndown ratio and easy field gas conversions.
2″ venting up to 65′ (including schedule 40 PVC).Vent Installation Detector (VID) for added safety.
Patented stainless steel fire tube heat exchanger Navien’s innovative heat exchanger design is ASME‑Certified,“H” Stamped, and reduces high-stress point weld failures common on other combi-boilers.
NHB integrated control provides industry-leading options and features including adjustable heat capacity, temp boost for outdoor reset control, adjustable anti-cycle timer and freeze protection.
The condensing technology of the dual stainless steel heat exchangers saves energy, reduces greenhouse gasses.
1/2″ gas pipe capability up to 24′ (subject to local codes). Cuts installation time, no need to install new gas lines for retrofit applications.
The sophisticated gas flow control system provides a high turndown ratio which reduces energy waste and excessive boiler cycling.
