Navien enters HVAC with forced-air hydro-furnace

January 10, 2024 By    

Navien started shipping the NPF forced-air hydro-furnace. Available in upflow and horizontal configurations, the NPF comes in two sizes: 60,000 Btu/hr and 100,000 Btu/hr. Both boast 97 percent AFUE, use high-efficiency ECM motor technology and meet the requirements of SCAQMD rule 1111 for ultra-low NOx performance. The NPF uses Navien’s stainless steel heat exchangers to heat water in an isolated compartment out of the airstream, which provides sound reduction and energy efficiency. The heated water is circulated through a hydronic coil, which transfers the heat into the airstream. The sealed combustion design allows the NPF to deliver comfortable heat without significantly impacting humidity levels. Water can be supplied to the NPF either through an auto-fill 0.25-in. water connection or through an easily accessible manual fill water reservoir.
