Hydro-Furnaces
High Efficiency Gas Hydro-Furnaces
Navien NPF high efficiency
hydro-furnaces provide consistent comfort while minimizing energy consumption
The NPF heats water by burning gas in a 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 minimizes noise. By exposing the air to much lower temperatures than a conventional gas furnace, there is less of an impact on the conditioned air humidity level.
The Navien NPF hydro-furnace is 97% AFUE and; uses standard gas lines and ductwork, making it a smart, comfortable replacement for traditional forced-air furnaces.

Heating air with warm water is so comfortable
NPF Hydro-furnace
- Durable stainless steel combustion heat exchanger located outside the airstream.
-
Hydronic coil transfers heat from the water into the conditioned airstream at temperatures up to 150ºF
Conventional furnace
-
Gas combustion directly heats the conditioned airstream — exposing it to temperatures up to 1000ºF
Our unique hydronic forced-air heating design keeps combustion in a separate, fully enclosed compartment for safe and quiet comfort.
NPF Upflow & Horizontal hydro-furnaces
The NPF hydro-furnace leverages our advanced knowledge of tankless water heaters, combi boilers and boilers. We’ve modified this technology to reinvent forced air heating.
Navien offers two premium, high-efficiency hydro-furnace series: NPF Upflow and NPF Horizontal. Both gas, condensing forced-air furnace series are 97% AFUE and available in 60,000 BTU/h (9,000-60,000 capacity) and 100,000 BTU/h (14,000-100,000 capacity) sizes.

- Continuously monitors air temperature & automatically adjusts capacity and airflow to maximize comfort & efficiency
- Robust airflow is sustained up to 1.0” external static pressure for use with today’s high-efficiency high-static air filtration systems
- Unique hydronic forced air heat exchanger design keeps combustion in a separate compartment outside of the heating air stream for quieter operation
- Easily integrates with smart HVAC systems & home automation platforms
- Dual-fuel compatible (gas or electric heating with heat pump) when matching with any AHRI-matched heat pump
- When paired with an AC or HP system, the variable capacity blower can be customized for a comfortable, quiet cooling experience
- Independent airflow for air conditioning, heat pump and fan-on settings provides year-round custom comfort
NAVIEN HYDRO-FURNACE BENEFITS
Warm up to the advantages of Navien hydro-furnace forced-air technology
The NPF hydro-furnace relies on Navien's unique heat exchanger and condensing technology to maximize system efficiency and comfort.
Proven heat exchanger design
Stainless steel condensing heat exchanger saves energy and comes with a limited lifetime warranty.
Variable speed blower motor
ECM variable speed blower motor qualifies for most gas furnace efficiency incentives.
Environmentally friendly design
Every unit meets SCAQMD Ultra-low NOx requirements, minimizing potentially harmful emissions.
Low cost installation & multiple venting options
High-efficient condensing technology allows for cost-saving PVC venting. Also, all models are equipped with a Vent Installation Detector (VID) for added safety during installation and maintenance.
Low noise levels
Unlike traditional forced air furnaces, the NPF hydro air heat exchanger design keeps combustion in a separate compartment outside of the heating air stream for quieter operation.
Simple setup & troubleshooting
EZNav control panel provides easy intuitive steps for startup & optional configurations. Self-diagnostics provide a direct readout in clear text, saved in non-volatile memory.
EXPLORE NAVIEN HYDRO AIR HEATING APPLICATIONS
Enjoy high-efficiency heating wherever & whenever you need it
- Variable capacity operation is like having many furnaces in one: low heat for milder days, high heat on colder days & more even temperatures year-round (compared to traditional single or two-stage furnaces)
- More efficient zoning & temperature control
- Models available for vertical (upflow) or horizontal flow, including attics & suspended installations
- Primarily designed for residential home heating applications
- Can also be used in non-industrial commercial applications such as schools, office buildings, churches, retail stores, nursing homes and hotels
Reduce Your Carbon Footprint with Navien’s Eco-Friendly Hydro-furnace
The NPF is designed with environmental sustainability in mind, boasting a 97% AFUE and Ultra Low NOx compliance. It qualifies for regional incentives, reduces energy bills, and enhances the efficiency of air conditioning and heat pump systems.
