The NPF in action
"If you're coming from a furnace retrofit background and have installed many furnace replacements, putting this in is no different. In fact, I found it way easier because I'm not messing around with dozens of little dip switches."
Brandon Farr, Farr Mechanical
"With the variable capacity on this particular furnace, the NPF, it's extremely quiet. Sometimes it's hard to even tell it's operating. The homeowner mentioned several times after the fact that he can't believe how quiet it is."
Colin Sadler,
John Sadler Plumbing & Heating
"Setting up the @navieninc NPF has never been easier with the “Setup Wizard” 🧙🏻♂️
Many of you may be familiar with this since the upgrade to the on-demand units. The NPF includes many of the same settings with the addition of water fill and airflow features."

"Having the flexibility to run my gas or condensate on either side of the unit is a great feature, and the set up wizard makes for an easy install!
Not to mention how quiet the unit was when it was operating!."

The NPF difference
The new NPF Hydro-furnace applies our expertise in condensing tankless water heaters and boilers to revolutionize forced air heating.
In conventional gas furnaces the combustion heat exchanger is located in the conditioned airstream. This exposes the air to very high temperatures that can dry out the air. The NPF Difference: The NPF heats water by burning the gas in a Stainless Steel sealed combustion heat exchanger, completely isolated from the airstream. The heated water is then pumped through a hydronic heat exchanger that gently transfers the heat into the air.
This unique method improves operational control, provides safe and even heating, and keeps operating sounds to a minimum. By exposing the air to much lower temperatures, there is less impact on the conditioned air humidity level.

Variable Capacity Technology... smarter softer heating
The NPF’s intelligent Variable Capacity System operates at 15%–100% capacity, optimizing air temperatures and airflow to maximize comfort and energy efficiency.
Easy installation
Navien’s NPF hydro-furnace is advanced, not complicated: we’ve made it easier than ever to replace a conventional forced-air furnace with hydronic forced air.
- Factory-formed full perimeter discharge flange makes duct connections & sealing easy
- On high-airflow installations, the profile readily allows side & bottom return
- Each unit is supplied with an LP conversion kit, as well as a natural gas high-altitude kit for installations up to 10,100 ft elevation
- Every NPF model is approved for one or two pipe vent installations
- New NPF700 furnace will match with standard width coils
- Standard left-side gas, electrical & water connections are field convertible to right side
- Unit can be manually filled with water or attached to an active water source using a ¼” connection
- Clearly marked Molex terminal strip & board located at the front of the blower compartment make control wire connection quick & easy
Simplify Setup
NPF's EZNav™ control panel uses simple text and icons to make it easy for technicians to configure the unit and, reduces downtime.
- Unit-mounted control panel provides direct readout in clear text, including diagnostic alerts & reminders
- Control panel includes Set-Up Wizard that walks installer through simple unit configuration
- Independent settings for discharge air temperature & air flow allow the system to optimize performance
- Adjust & monitor supply and return air temperatures using the built in sensors
- Integrated non-volatile self-diagnostics make identifying & correcting any problem a snap
- Status panel provides easy-to-read graphics & settings information
Two premium, high-efficiency Hydro-furnace models:
NPF Upflow and NPF Horizontal
The innovative Hydro-furnace can be your next level of growth for your business.
