Navien introduces NFP Hydro-furnace
October 4, 2023 | By HPAC Magazine
The unit uses heat exchangers to heat water which is circulated through a hydronic coil to transfer heat into the airstream.
Navien has revealed its NPF Hydro-furnace, the company’s introduction into the HVAC market.
Available in upflow and horizontal configurations, the NPF comes in two sizes: 60,000 Btu/h and 100,000 Btu/h that both feature 97% AFUE and meet the SCAQMD rule 1111 for ultra-low NOx performance.
The NPF uses Navien’s dual 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 provide heat without significantly impacting humidity levels and at one of the quietest sound levels of any furnace on the market, says the company.
The NPF offers variable capacity that can modulate down to 15%.
The unit’s EZNav interface with built-in setup wizard provides intuitive steps for startup, configuration, and diagnostics.
Installers can set supply air temperature and airflow directly from the front panel, and the service wizard will walk contractors through component verification to aid in troubleshooting.
Each NPF unit is compatible with most one- and two-staged thermostats and can be matched with any AC or heat pump system providing their own dedicated airflow selections and ramping profiles.
The company will begin shipping the NPF upflow units in the first week of November 2023, and the NPF horizontal configuration in January 2024.
