Navien is a leading name in high-efficiency hydronic heating technology, trusted by homeowners and HVAC professionals across North America. Best known for their innovation in tankless water heaters and combi-boilers, Navien has applied that same engineering expertise to reinvent forced-air heating with their NPF Series Gas Hydro-Furnaces. These systems represent a fundamental departure from conventional gas furnaces. Instead of burning gas directly in the airstream, Navien’s NPF hydro-furnaces heat water in a sealed stainless steel combustion heat exchanger and then transfer that warmth into your home’s air through a hydronic coil. The result is quieter, safer, and more consistent comfort throughout your living space.
The Navien NPF Series achieves an industry-leading 97% AFUE (Annual Fuel Utilization Efficiency) rating, meaning nearly all the fuel consumed is converted directly into useful heat for your home. This makes Navien hydro-furnaces one of the most efficient forced-air heating options available today, and a smart long-term investment for homeowners looking to reduce energy bills without sacrificing comfort. All NPF models feature variable capacity operation ranging from 15% to 100%, allowing the system to continuously monitor and adjust output based on real-time temperature demands rather than simply cycling on and off.
Navien NPF hydro-furnaces are engineered to work with your existing gas lines and standard ductwork, making them a straightforward replacement for aging conventional furnaces. They’re Ultra-Low NOx compliant, dual-fuel compatible, and designed for easy integration with smart HVAC systems and home automation platforms. Whether you’re upgrading an older system or building a new home in Denver, CO, Navien’s hydro-furnace technology delivers a level of efficiency, comfort, and engineering quality that sets it apart from traditional forced-air alternatives.

97% AFUE hydronic forced-air heating — the smart replacement for conventional gas furnaces.
The Navien NPF Series is the brand’s complete line of high-efficiency gas hydro-furnaces, engineered around a patented hydronic forced-air design that fundamentally reimagines how your home is heated. Rather than exposing conditioned air to direct combustion temperatures of up to 1,000°F as a conventional furnace does, the NPF heats water through a sealed stainless steel heat exchanger and then transfers that warmth through a hydronic coil, exposing air to temperatures of only up to 150°F. The difference is quieter operation, more even heat distribution, and significantly better humidity retention throughout your Denver, CO home.
The upright installation solution — designed for basements, utility rooms, and standard forced-air setups.
The Navien NPF Upflow is designed for homeowners whose existing HVAC setup calls for a vertical upflow configuration – the most common furnace orientation in homes with basement or utility room installations where conditioned air is delivered upward through the ductwork. Built on the same 97% AFUE hydronic platform as the full NPF line, the Upflow model brings Navien’s advanced stainless steel heat exchanger technology and variable capacity operation to the most widely used furnace installation format in Denver, CO and across North America.
Space-saving horizontal configuration — built for crawl spaces, attics, and side-discharge installations.
The Navien NPF Horizontal is engineered for homes where a vertical upflow installation simply isn’t practical, including properties with crawl spaces, attic-mounted air handlers, or tight mechanical rooms that require a side-discharge configuration. Sharing the same core hydronic forced-air technology as the NPF Upflow, the Horizontal model delivers identical 97% AFUE performance and variable capacity operation in a layout designed to maximize flexibility across a wider range of Denver, CO home types and construction styles.
