The NPF Hydro-furnace is available in upflow and horizontal configurations, and comes in two sizes of 60,000 BTU/h and 100,000 BTU/h that both boast 97.0% AFUE, utilize high-efficiency ECM motor technology, and meet the stringent requirements of SCAQMD rule 1111 for Ultra-Low NOx performance. The NPF uses Navien’s industry-proven 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 for the ultimate in quiet forced-air heating comfort. The sealed combustion design allows the NPF to deliver comfortable heat without significantly impacting humidity levels.
